Scoping Review: The Effectiveness Of Sanitation Interventions In Addressing Waterborne Diseases In Vulnerable Communities

2026-06-17T23:02:33+00:00

Waterborne diseases remain a serious public health concern in vulnerable communities, particularly in areas with inadequate sanitation. WHO reported approximately 505,000 diarrhea-related deaths annually due to unsafe drinking water. Indonesia's 2023 Health Survey showed diarrhea prevalence of 4.3% across all age groups. This scoping review aims to critically map and evaluate the effectiveness of various sanitation interventions in combating waterborne diseases in vulnerable communities based on current scientific evidence. The scoping review followed the Arksey and O'Malley (2005) framework, strengthened with JBI guidance, and reported using PRISMA-ScR guidelines. Searches were conducted through Google Scholar, PubMed, and Scopus (2020-2025). Sixteen articles were analyzed using descriptive thematic analysis. Multi-component sanitation interventions combining behavioral change with infrastructure provision demonstrated higher effectiveness than single interventions. Point-of-use water treatment reduced diarrhea risk by up to 50%, while handwashing with soap reduced risk by 30%. CLTS/STBM programs significantly improved latrine coverage and reduced diarrhea prevalence. Intervention effectiveness was moderated by seasonal variation, geographic context, and community participation levels. Multi-component approaches integrating behavioral change, infrastructure improvement, and institutional strengthening proved most effective. Significant research gaps exist regarding long-term sustainability, cost-effectiveness analysis, and climate change adaptation.

Anemia among adolescent girls remains a significant public health problem because it can adversely affect growth, learning capacity, productivity, and future reproductive health. In addition to nutritional factors, modern lifestyle changes—including physical activity, sleep quality, and gadget use—are increasingly recognized as potential contributors to anemia risk. This study aimed to synthesize scientific evidence regarding the association of physical activity, sleep quality, and gadget use with anemia among adolescent girls. This study aimed to analyze and synthesize scientific evidence regarding the association of physical activity, sleep quality, and gadget use with anemia among adolescent girls and to identify the underlying mechanisms linking these factors to anemia. This study employed a Systematic Literature Review (SLR) following the PRISMA 2020 guidelines. Literature searches were conducted in the PubMed, Scopus, ScienceDirect, ProQuest, Google Scholar, and Garuda databases for articles published between 2020 and 2025. Studies were selected based on predefined inclusion and exclusion criteria, assessed for methodological quality, and analyzed using narrative synthesis and thematic analysis. A total of 25 articles met the eligibility criteria and were included in the final synthesis. The review findings indicated that unbalanced physical activity, poor sleep quality, and excessive gadget use were associated with an increased risk of anemia among adolescent girls. Both insufficient and excessive physical activity without adequate nutritional support may affect hemoglobin levels. Poor sleep quality was linked to impaired iron metabolism and hemoglobin synthesis, while excessive gadget use indirectly contributed to anemia through increased screen time, sedentary behavior, and reduced sleep quality. These findings suggest that these three lifestyle factors interact and collectively influence the risk of anemia. In conclusion, preventing anemia among adolescent girls requires a comprehensive approach that addresses not only nutritional factors but also healthy physical activity, adequate sleep, and responsible gadget use. The findings provide evidence for developing adolescent health programs and future research on lifestyle determinants of anemia.

2026-06-03T08:51:01+00:00

Stunting remains a significant chronic nutritional challenge in Indonesia. Early Initiation of Breastfeeding (EIB) and Exclusive Breastfeeding (EBF) are critical interventions that support child growth and serve as foundational strategies for stunting prevention. This study aims to investigate the relationship between a history of EIB and EBF and the severity of stunting (classified as stunted and severely stunted) among affected children under five within the catchment area of Public Health Center "X" in Indragiri Hilir Regency.An observational analytic design with a cross-sectional approach was employed, utilizing secondary data from the 2025 Stunting Audit. The study population consisted of 45 stunted children under five, selected through a total sampling technique. Data were analyzed using the Chi-Square test with a 95% confidence level (α=0,05) and the calculation of Odds Ratios (OR).The results indicated that the majority of respondents were categorized as severely stunted (66.7%), had a history of EIB (55.6%), and received EBF (55.6%). No significant correlation was found between a history of EIB and stunting severity (p=0,670; OR=1,313; 95%CI=0,373–4,616). Conversely, a significant association was observed between EBF and stunting severity (p=0,034; OR=0,250; 95%CI=0,067–0,931). These findings suggest that exclusive breastfeeding serves as a protective factor against increased stunting severity, whereas EIB did not demonstrate a significant relationship in this specific population. Consequently, enhancing EBF coverage must be prioritized as a pivotal component of stunting prevention and control programs.

Literature Review: The Relationship Between Dietary Patterns, Physical Activity, And Medication Compliance With The Increase In Blood Sugar Levels In Diabetes Mellitus Patients

2026-06-20T12:24:58+00:00

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia due to impaired insulin secretion or action. Blood glucose control in patients with type 2 diabetes mellitus is influenced by various factors, including dietary patterns, physical activity, medication adherence, as well as psychosocial factors such as stress and family support. This study used a literature review method by searching scientific articles through Google Scholar, PubMed, and ScienceDirect within the publication period of 2022–2026. Selected articles focused on the relationship between diet, physical activity, and medication adherence with blood glucose levels in patients with type 2 diabetes mellitus. The review findings indicate that most studies show a significant relationship between dietary patterns, physical activity, and medication adherence with blood glucose levels. Physical activity and dietary adherence contribute to better glycemic control, while medication adherence shows inconsistent results. Other factors such as family support, stress levels, and smoking habits also influence blood glucose stability. Blood glucose control in diabetes mellitus is multifactorial. Proper diet and regular physical activity improve insulin sensitivity and glucose metabolism. Medication adherence is important, but not always directly associated with glycemic control due to the influence of individual and lifestyle factors. Dietary patterns, physical activity, and medication adherence play important roles in controlling blood glucose levels in patients with type 2 diabetes mellitus, although results are not always consistent. Diabetes management requires a comprehensive approach including lifestyle modification and psychosocial support.

2026-06-12T13:40:27+00:00

Musculoskeletal Disorders (MSDs) are musculoskeletal system disorders affecting muscles, joints, tendons, and supporting tissues that may arise due to non-ergonomic working postures and repetitive occupational activities. Hospital management employees are considered a high-risk group for MSDs because their work predominantly involves prolonged sitting and extensive computer use. This study was conducted to examine the association between work posture and repetitive movements with the occurrence of Musculoskeletal Disorders (MSDs) among management employees at Prof. Dr. H.M. Chatib Quzwain Regional Hospital, Sarolangun. An analytical observational study with a cross-sectional design was employed. The study involved 31 respondents selected through purposive sampling. Data were obtained using the Nordic Body Map (NBM) questionnaire to identify MSD complaints, the Rapid Upper Limb Assessment (RULA) method to evaluate work posture, and direct observation to assess repetitive work activities. Data analysis was carried out using univariate and bivariate techniques with the Chi-Square test at a 95% confidence level. The findings revealed that 58.1% of respondents experienced moderate MSD complaints, 80.6% demonstrated high-risk work postures, and 54.8% engaged in repetitive work activities categorized as risky. The bivariate analysis showed that work posture was not significantly related to MSD occurrence (p = 0.656), whereas repetitive movements had a significant association with MSDs (p = 0.022). These findings indicate that repetitive work activities play a more substantial role in the development of MSDs than work posture among hospital management employees. Therefore, the implementation of ergonomic workplace practices and adequate rest periods is recommended to minimize the risk of MSDs.

The Role Of Periapical Radiography In Identifying Channel Configurations Type II Vertucci Root In The First Premolar Tooth Of The Maxim

2026-06-18T00:52:58+00:00

The first premolar maxillary has a complex diversity of root canal configurations. Identification of the proper root canal configuration greatly determines the success of endodontic treatment. Periapical radiography remains an easily accessible and useful examination to detect the possibility of more than one root canal through radiograph retrieval with the principle of Same Lingual Opposite Buccal, i.e. horizontal angulation changes and canal shadow variation analysis. To report the role of periapical radiography in identifying the configuration of the Vertucci root canal type II in the first premolar of the maxillary and its implications for endodontic management. A 39-year-old male came in with a complaint of cavities in the first premolar tooth of the left maxillary (Tooth 24). Initial periapical radiographs show the suspicion of the presence of more than one root canal. Taking radiographs with angulation variations helps to clarify the relationship of the root canal, which appears to be separate in the coronal and middle part of the root and then merge before reaching the apex, according to the Vertucci type II configuration. The radiography findings were used as a basis for determining treatment strategies and were confirmed on postoperative radiographs. Periapical radiography with angulation variations and SLOB principles remains valuable in detecting type II Vertucci configurations and aiding in the planning and implementation of more accurate root canal treatments.

2026-06-26T12:40:26+00:00

Malocclusion can affect both oral aesthetics and function, one manifestation of which is multiple diastema, defined as spaces between two or more adjacent teeth. This condition is often accompanied by a maxillary midline deviation, which may compromise dental aesthetics and occlusal harmony. The management of multiple diastema requires a multidisciplinary approach aimed at closing interdental spaces, correcting midline deviation, and eliminating etiological factors. Removable orthodontic appliances may serve as a viable treatment option because they are simple, easy to fabricate, and more cost-effective than fixed appliances. This case report aims to describe the management of maxillary multiple diastema associated with midline deviation using a removable orthodontic appliance in the form of an active plate. A 24-year-old female patient presented with spacing between the anterior teeth of the maxillary arch. Clinical examination and supporting analyses revealed a skeletal Class III relationship with a maxillary arch excess space of 1.6 mm. The treatment plan focused on the closure of multiple diastema and correction of the maxillary midline deviation using an active plate. Periodic activation of the appliance was performed to achieve tooth movement for space closure and midline correction. Evaluation after three months of treatment demonstrated successful closure of the multiple diastema and improvement of the maxillary midline while maintaining normal occlusal relationships. This case report concludes that removable orthodontic treatment using an active plate is effective for diastema closure and midline correction in selected mild-to-moderate cases, particularly in cooperative adult patients.

Logistics management activities in hospitals have complex work characteristics and often involve intensive physical workloads. This study aims to identify potential ergonomic hazards, analyze risk levels, and formulate risk control recommendations for manual material handling (MMH) activities at the Medical Devices Warehouse Installation of RSUD Pelabuhan Ratu. The implementation methods utilized during this residency included direct field observations and structured interviews with warehouse staff. The root cause analysis was qualitatively conducted using a fishbone diagram with 4M+1E parameters (man, method, material, machine, environment) , followed by problem prioritization using the USG (Urgency, Seriousness, Growth) method and intervention strategy formulation through SWOT analysis. The assessment findings revealed significant potential ergonomic risks due to piles of large and heavy medical equipment being handled manually without mechanical lifting equipment (such as forklifts or hand stackers). Limitations in narrow storage spaces, the absence of OSH (Occupational Safety and Health) signages, and the lack of a specific recording system for musculoskeletal disorders (MSDs) further aggravated the risk level. Based on the USG matrix, the most urgent primary issues are the high intensity of manual heavy lifting and the low awareness among employees regarding proper ergonomic working postures. The SWOT analysis positioned the organization in Quadrant I (Aggressive Strategy). Consequently, the SO (Strength-Opportunity) strategy is recommended to optimize management support by developing an integrated manual handling system with the hospital's OSH programs, conducting regular training and socialization on proper lifting techniques, installing educational OSH signs, and strengthening progressive supervision and evaluation to minimize musculoskeletal injuries among warehouse workers.

Analysis Of Challenges And Implementation Of Digital Health Policy Transformation: A Literature Review

2026-06-13T14:00:20+00:00

The acceleration of global health digitalization offers significant potential to improve public care quality; however, its practical execution frequently encounters multidimensional barriers and threatens to widen the digital health divide. Objective: This study aims to comprehensively evaluate the policy typologies, service modalities, contemporary challenges, and real-world implications of international digital health implementations. Method: Utilizing a Systematic Literature Review (SLR) design aligned with PRISMA 2020 guidelines, literature searches were performed across PubMed, ScienceDirect, and Google Scholar databases for articles published between 2022 and 2026. Applying rigorous selection via the PICOS framework, 8 core articles were retrieved for extraction using thematic analysis. Results: The synthesis reveals that macro-level policies successfully diversified digital services into administrative (e-prescription), remote clinical care (Remote Patient Monitoring), and preventive governance (Digital Proximity Tracing). Instrumentally, e-health effectively reduces operational costs, enhances clinical quality, and bridges access gaps for marginalized groups, such as coastal and migrant populations. Nevertheless, the transition is severely hindered by fragmented data interoperability, insufficient digital literacy among professionals, ethical issues concerning AI algorithmic biases, and policy blindness toward technological determinism, which drives social exclusion. Conclusion: Integrating social determinants into digital health architecture is vital for establishing an equitable public health ecosystem. Policymakers must devise equity-centered regulations and system standardization, while medical institutions are urged to adopt structured literacy training to minimize internal resistance.

An Overview of Online Loan (Pinjol) Usage Among Medical Students of Universitas YARSI, Cohorts 2023–2024, and Its Review from an Islamic Perspective

2026-05-31T23:04:12+00:00

The increasing accessibility of online loan (pinjol) services has influenced financial behavior among students, potentially leading to consumptive habits and financial risks. Among medical students with demanding academic responsibilities, the use of online loans may impact financial stability and decision-making. From an Islamic perspective, financial transactions must comply with Sharia principles, avoiding elements such as riba (usury), gharar (uncertainty), maysir (gambling), and zhulm (injustice). This study aims to analyze the overview of online loan usage among Medical Students of Universitas YARSI Cohorts 2023–2024 and examine it from an Islamic perspective. This study used a quantitative survey design with a total sampling technique involving active medical students of Universitas YARSI Cohorts 2023–2024 who met the inclusion criteria. Data were collected through an anonymous online questionnaire distributed via Google Forms using Likert-scale (1–5) questions. The variables measured included economic factors, social factors, consumptive behavior, ease of access, and financial impact. The instrument was tested for validity and reliability prior to data collection. The findings indicate that the main factors influencing online loan usage among students are ease of access and consumptive lifestyle, both showing significant relationships with usage behavior. Economic and social factors were not significantly associated. Online loan usage is linked to higher consumptive behavior and has implications for students’ financial conditions, including potential financial burden. Students generally perceive online loans as a practical and quick financial solution. Some respondents exhibit repeated usage patterns, indicating a risk of dependency. Awareness of the risks and intention to reduce usage were observed among a portion of students. Differences were also found in understanding online loans as riba, with non-users demonstrating better awareness. Online loan usage among YARSI medical students is primarily driven by convenience and consumptive behavior, with notable impacts on financial management. From an Islamic perspective, online loans are permissible only if they adhere to Sharia principles. However, most conventional online lending practices involve elements of riba and are therefore not permissible, highlighting the need for greater financial literacy and caution among students.

The Effect Of Supplementary Food Supply (PMT) Supervision Local For Pregnant Women With Chronic Energy Deficiency (CED) On The Nutritional Status Of The Mother

2026-06-12T13:32:20+00:00

Chronic energy deficiency (CED) in pregnant women is a major public health challenge. Globally, the WHO reports that approximately 38 million pregnant women experience malnutrition each year, including CED, which contributes to an increased risk of maternal and neonatal mortality. In Indonesia, based on 2018 Riskesdas data, the prevalence of CED in pregnant women reached 17.3% (Ministry of Health of the Republic of Indonesia, 2023b). CED in pregnant women, identified by an upper arm circumference (LILA) of less than 23.5 cm, has serious impacts on maternal and fetal health, such as increasing the risk of low birth weight (LBW), premature birth, hypothyroidism, and stunting (Supadmi et al., 2020). This problem poses a major challenge in efforts to reduce maternal and infant mortality and improve the quality of public health. This study aims to determine the effect of local supplementary feeding (PMT) assistance for pregnant women with chronic energy deficiency (CED) on maternal nutritional status. This research was conducted in May 2026. This type of research is quantitative research using a Pre-Experimental design with a one group pretest posttest design approach . The sampling technique was carried out using a purposive sampling method . The sample used in this study was 18 respondents. The instruments used were questionnaires and PMT assistance sheets. The average nutritional intake before assistance was 42.3 calories and after assistance was 73.4 calories, while the LiLA measurement before assistance was 22.3cm and after assistance was 23.3cm. There is an effect of local supplementary feeding assistance (PMT) for pregnant women with chronic energy deficiency (KEK) in the work area of the Sindang Danau Health Center UPT on maternal nutritional status, with an increase in nutritional intake between 20.9 calories to 38.6 calories and an increase in LiLA size between 0.5 cm to 1.6 cm.

Case Journal “Bronchopneumonia In Adult Patients”

2026-06-25T09:25:19+00:00

Bronchopneumonia is a lower respiratory tract infection characterized by inflammation of the bronchioles and alveoli caused by microbial infection. It remains a significant cause of morbidity and mortality, particularly among older adults and individuals with underlying risk factors. This case journal aimed to describe the clinical manifestations, diagnostic approach, and management of bronchopneumonia in an adult patient. A case report method was employed using data obtained from medical records, including history taking, physical examination, laboratory investigations, radiological findings, and therapeutic evaluation during hospitalization. A 58-year-old male presented with shortness of breath, productive cough with yellowish sputum, fever, and chest pain during coughing. Physical examination revealed tachypnea, coarse crackles, increased tactile fremitus, and dullness to percussion over the right lower lung field. Laboratory investigations demonstrated leukocytosis and elevated C-reactive protein levels, while chest radiography showed multiple patchy infiltrates in both lower lung fields. The patient was diagnosed with bronchopneumonia and treated with antibiotics, oxygen supplementation, mucolytic therapy, and supportive management. Accurate diagnosis and appropriate management contributed to clinical improvement and reduced the risk of complications associated with bronchopneumonia.

Distribution of Diphtheria Cases by Population Density and Access to Health Centers in East Java Province, 2022–2024

2026-04-29T03:09:47+00:00

Diphtheria remains a re-emerging public health threat in Indonesia, with East Java Province consistently reporting the highest national case burden. This study aimed to describe the spatial distribution of diphtheria cases in relation to population density and healthy home coverage across all 38 districts and cities of East Java Province from 2022 to 2024. An ecological study design with a temporal-spatial approach was employed using secondary data sourced from the East Java Provincial Health Profile for the period 2022–2024. Data were analyzed and visualized using Quantum GIS version 3.34.3 through choropleth and spatial overlay mapping techniques. A total of 909 diphtheria cases were recorded over the study period, with annual increases culminating in 397 cases in 2024. Sidoarjo Regency (74 cases), Surabaya City (68 cases), and Blitar Regency (66 cases) recorded the highest cumulative case counts. Spatial overlay analysis revealed that districts and cities classified with high population density tended to exhibit higher diphtheria case burdens, while areas with low healthy home coverage most notably Bangkalan Regency also showed elevated case counts. Conversely, Madiun City, which had the highest healthy home coverage, recorded only 7 cases throughout the study period. These findings indicate that population density and healthy home access are associated with the geographic distribution of diphtheria incidence, underscoring the need for territory-based, multi-sectoral prevention and control strategies in high-risk districts.

Characteristics And Acceptability Of Crispy Noodles Made With Corn (Zea Mays L.) And Inulin Flour Substitutes

2026-06-08T12:48:43+00:00

Obesity is a growing nutritional problem, including in Indonesia. The habit of consuming high-calorie, low-fiber foods such as noodles contributes to the risk of obesity. Corn silk, often considered waste, is rich in fiber, flavonoids, saponins, tannins, beta-carotene, and other vitamins that are beneficial to health. Corn silk is produced in abundance; specifically, for every 5 tons of corn, 3.5% consists of corn silk. The potential for utilizing this byproduct can be combined with inulin flour, which is high in fiber content and has prebiotic properties. This study aims to determine the effect of substituting corn silk flour and inulin flour on the acceptability of crispy noodle products. The research design used was a pure experimental design with a completely randomized design (CRD), consisting of 3 formulations: one control formulation (F0) and two modified formulations (F1, F2). The panelists were 30 adults aged 18 years and older. The acceptability test results showed that the modified formula most preferred by the panelists was F1. There were significant differences in color, taste, texture, and aftertaste characteristics (p ≤ 0.05). Thus, the substitution of corn silk flour and inulin flour in crispy noodle products is still sensorially acceptable, with F1 as the best modified treatment formula.

Analysis Of Sea Surface Temperature Trends And Their Relationship With The Indian Ocean Dipole (IOD) In The Southern Waters Of Java During The 2000–2025 Period

2026-06-29T22:01:10+00:00

Sea Surface Temperature (SST) is a key oceanographic parameter that regulates heat exchange between the atmosphere and the ocean; however, the current trend of global warming threatens thermal stability in tropical regions. This study aims to analyze long-term SST warming trends and identify their response and temporal relationship with the Indian Ocean Dipole (IOD) phenomenon in the southern waters of Java. A quantitative approach was applied using GLORYS12v1 ocean reanalysis data for the period 2000–2025, which were statistically analyzed using the Mann–Kendall test, Sen’s Slope estimator, and lag correlation analysis. The results indicate a highly significant increasing trend in annual SST (Z = 3.791; p = 0.000) with a warming rate of +0.0295°C/year. The highest mean SST occurred during the MAM season (29.17°C), while the lowest was observed during the JJA season (27.16°C). Regarding the IOD phenomenon, the Dipole Mode Index (DMI) and SST anomalies exhibited an inverse relationship with a correlation coefficient of r = −0.47 at a 0-month lag. Positive IOD phases were associated with SST cooling anomalies of up to −0.356°C, whereas negative IOD phases warmed the waters by up to 0.996°C. The consistent warming trend, combined with strong seasonal variability and a relatively weak response to IOD phases, suggests that SST dynamics are not solely controlled by the IOD. The findings demonstrate that the southern waters of Java have experienced significant ocean warming over the last two decades, while IOD variability plays a role in temporally modulating SST changes.

Factors Influencing Compliance With The Use Of Personal Protective Equipment By PT. Wiradijaya Workers In 2026

2026-06-12T00:46:00+00:00

Occupational safety and health is an important aspect in industries with high work risks, including the oil and gas sector. Compliance with the use of personal protective equipment (PPE) is one of the main efforts to prevent occupational accidents and diseases. This study aims to identify factors associated with PPE use compliance among workers at PT. Wiradijaya in 2026. The study used an analytical observational design with a cross-sectional approach involving 90 workers selected by total sampling. Data were collected using validated and reliable questionnaires. The variables studied included knowledge, attitudes, supervision, motivation, and PPE use compliance. Data analysis was performed using the Chi-Square test. The results showed that most respondents had high compliance in PPE use (55.6%), good knowledge (53.3%), good attitudes (71.1%), good supervision (67.8%), and high work motivation (58.9%). Bivariate analysis indicated significant relationships between knowledge and PPE compliance (p=0.022), attitude and PPE compliance (p=0.016), supervision and PPE compliance (p=0.001), and work motivation and PPE compliance (p=0.037). Supervision was identified as the strongest factor associated with compliance. It can be concluded that individual and organizational factors influence workers' PPE compliance. Strengthening supervision, continuous safety training, and increasing worker motivation are recommended to improve PPE use compliance in the workplace.

Improving Students' Knowledge About The Importance Of Physical Activity Through Health Counseling At Mts Al Madani Sasak Panjang Bogor School

2026-06-25T09:22:56+00:00

Lack of physical activity among adolescents is becoming an increasingly worrying global health problem. WHO data (2022) shows that more than 80% of adolescents worldwide are not physically active enough, while the 2018 Basic Health Research (Riskesdas) recorded that 33.5% of Indonesia's population aged ≥10 years were physically inactive, with West Java reaching 37.5%. This study aims to determine the increase in students' knowledge about the importance of physical activity through health education based on the Health Belief Model (HBM) at MTs Al Madani Sasak Panjang, Bogor Regency. The study used a descriptive qualitative approach with pre-test and post-test questionnaire instruments administered in May 2026 to 9th grade students. The results showed an increase in three HBM components: perceived susceptibility increased from 23 to 26, perceived severity from 27 to 28, and perceived barriers from 18 to 22. Meanwhile, perceived benefits did not change (remained at 44), indicating a ceiling effect because students already had a fairly good understanding of the benefits of physical activity before the intervention. The largest improvement occurred in the perceived barriers component, indicating students were increasingly aware of real barriers such as limited time, laziness, lack of facilities, and the influence of device use. It was concluded that HBM-based health education was effective in increasing students' awareness of the risks and barriers to physical activity. Schools are advised to make this program a routine and ongoing activity, with concrete strategies to address the identified barriers.

2026-06-03T08:52:26+00:00

Globally and nationally, patient satisfaction levels still fall short of SPM standards, especially in government hospitals. The decline in visits and patient satisfaction indicates a gap in healthcare service quality that needs to be addressed. This study aims to analyze the effect of service quality on inpatient satisfaction at Syekh Yusuf Regional Hospital, Gowa Regency. This study used a quantitative method with an observational analytical approach and a cross-sectional design. A total of 135 respondents were selected using purposive sampling. Data were collected through questionnaires and analyzed using chi-square and multiple linear regression. The results showed that all dimensions of service quality (SERVQUAL)—tangibles (p=0.039), reliability (p=0.002), responsiveness (p=0.016), assurance (p=0.000), and empathy (p=0.000)—had a positive and significant effect on patient satisfaction. The most dominant variable influencing patient satisfaction was assurance (β=0.285). Although the quality of inpatient services at Syekh Yusuf Regional Hospital was generally good (43%), improvements are still needed in several service aspects to optimize patient satisfaction and improve the quality of healthcare services.

The Effect Of Ergonomic And Physical Work Environment Factors On Musculoskeletal Disorders (Msds) In Batik Craftsmen In Danau Teluk District

2026-06-13T01:04:17+00:00

Musculoskeletal disorders (MSDs) are disorders of the muscular and skeletal systems commonly experienced by workers due to unergonomic work postures, repetitive movements, long work durations, and unsupportive physical work environments. Batik artisans are among the workers at risk of developing MSDs because batik-making activities are static, repetitive, and performed over long periods. This study aims to determine the influence of ergonomic and physical work environment factors on musculoskeletal disorders (MSDs) among batik artisans in Danau Teluk District. This study used a quantitative method with an observational analytical cross-sectional design. The study was conducted among batik artisans in Danau Teluk District, Jambi City, with a sample of 40 respondents using a total sampling technique. Data were collected through interviews, observations, temperature and lighting measurements, and assessment of work posture using the Rapid Upper Limb Assessment (RULA) method and MSD complaints using the Nordic Body Map (NBM). Data were analyzed using the Chi-Square test and logistic regression at a 95% confidence interval. The study showed that 17 respondents (42.5%) experienced high-grade MSDs. There was a relationship between work posture (p-value = 0.001), work duration (p-value = 0.000), repetitive motion (p-value = 0.000), and lighting (p-value = 0.000) and the incidence of MSDs. Meanwhile, temperature had no relationship with the incidence of MSDs (p-value = 0.131). The results of the multivariate analysis showed that work posture was the most influential factor on the incidence of MSDs with a p-value = 0.006 and Exp(B) = 64.000. Ergonomic and physical work environment factors influence the incidence of Musculoskeletal Disorders (MSDs) among batik artisans in Danau Teluk District. Work posture is the dominant factor influencing the incidence of MSDs in batik artisans.

Analysis Of Generation Z’s Online Medication Purchasing Behavior

2026-06-27T03:59:46+00:00

The digital age has transformed the way Generation Z (Gen Z) accesses healthcare services, including obtaining medications. The phenomenon of “kereta kuning” purchasing medications through e-commerce platforms and social media has become a significant trend due to its convenience, privacy, and competitive prices. However, this convenience poses serious health risks. This article aims to provide a narrative review of online medication purchasing behavior among Gen Z and its impact on patient safety. We conducted a literature review by collecting scientific journals from leading platforms such as Google Scholar, CrossRef, and PubMed in English. Analysis of the literature reveals that low digital health literacy and a tendency to self-diagnose based on viral content are driving Gen Z to consume prescription medications without medical supervision. Key risks include the circulation of substandard or counterfeit drugs, a lack of accurate dosage information, and the absence of pharmacists in clinical screening. Although digital access offers efficiency, without strict regulations and adaptive education tailored to Gen Z’s lifestyle, this trend could become a public health “disaster” in the future.

2026-05-23T00:07:43+00:00

Primary dysmenorrhea is a gynecological complaint frequently experienced by adolescent girls and can disrupt their learning activities and quality of life. One non-pharmacological therapy that is developing in the community is the consumption of turmeric and tamarind drinks (sinom), which contain natural anti-inflammatory and analgesic compounds. This study aims to analyze the effectiveness of turmeric and tamarind drinks (sinom) on reducing the intensity of primary dysmenorrhea pain in adolescent girls at SMAN 1 Krucil. The study used a pre-experimental design with a one-group pretest-posttest approach. The study sample consisted of 41 respondents selected using a purposive sampling technique according to inclusion and exclusion criteria. Pain intensity was measured using the Numeric Rating Scale (NRS), then analyzed using the Wilcoxon Signed-Rank Test. The results showed that before the intervention, the majority of respondents experienced moderate pain (63.4%) and severe pain (19.5%). After administration of sinom, the majority of respondents were in the mild pain category (56.1%), and the proportion of severe pain decreased to 7.3%. The Wilcoxon test showed a Z value of -5.165 with a p-value <0.001, indicating a significant decrease in primary dysmenorrhea pain intensity after administration of the turmeric and tamarind drink (sinom). These findings indicate that sinom is effective as an alternative non-pharmacological therapy in reducing primary dysmenorrhea pain in adolescent girls and has the potential to be developed as a locally-based health intervention that is easily accessible and safe to use.

The Effectiveness Of Oxytocin Massage On Breast Milk Letdown In Postpartum Mothers In The Delivery Room Of Ampelgading Community Health Center

2026-07-02T11:56:30+00:00

Babies get all the nutrients they need to grow and develop optimally from breast milk, making it the ideal food source. Breast milk secretion issues are frequent among new moms, especially in the first few days after giving birth. One non-pharmacological approach to increasing milk production and secretion is oxytocin massage, which works by stimulating the release of the hormone oxytocin. In 2025, the goal of 80% was not met at Ampelgading Public Health Center, Ampelgading District, where the coverage of exclusive breastfeeding remained at 72%. The purpose of this research was to find out whether postpartum women could increase their milk production by massaging their breasts with oxytocin. The researchers in this study used a one-group pretest-posttest design based on previous research. Thirty pregnant women who had just given birth were randomly selected using the complete sampling technique. For three days, we monitored the secretion of breast milk both before and after performing an oxytocin massage. The Wilcoxon-marked assessment test was used to evaluate the data, with a significance level of α = 0.05 being used. According to the data, the majority of participants were between 26 and 30 years old, had experienced a termination of employment, had a minimum of Junior High School Education, were unemployed, and were among the youngest participants (10 respondents; 33.3%). After receiving oxytocin massage, the average amount of breast milk released increased from 6.93 cc to 24.83 cc. Statistically significant changes in breast milk secretion were seen before and after oxytocin massage administration, as indicated by a p value of 0.000 (p < 0.05) on the Wilcoxon Signed Rank test. Postpartum women who get an oxytocin massage report an increase in their milk production. Midwives may advise oxytocin massage as a postpartum intervention to help the mother secrete more breast milk.

The results showed that 32 respondents (57.1%) were classified as positive for drug abuse, 27 respondents (48.2%) had negative attitudes, and 34 respondents (60.7%) were exposed to negative peer influence. The Chi-square test showed a significant association between attitude and drug abuse (p = 0.028) and between peer influence and drug abuse (p = 0.001). This study concludes that attitude and peer influence are significantly associated with drug abuse among residents in West Baturaja District. Community-based prevention should strengthen protective attitudes, peer control, family supervision, and continuous health education.

Management Of Grade II Tooth Mobility Associated With Chronic Periodontitis Using A Fiber-Reinforced Composite Resin Extracoronal Splint: A Case Report

2026-06-12T13:41:22+00:00

Chronic periodontitis is defined as an inflammatory condition of the periodontal tissues caused by specific subgingival microorganisms, resulting in the progressive destruction of the periodontal ligament and supporting tissues of the teeth. The primary clinical characteristic of chronic periodontitis is detectable clinical attachment loss, often accompanied by periodontal pocket formation and changes in the density and height of the alveolar bone. This condition may lead to pathological tooth migration, resulting in diastema formation and increased tooth mobility, which can ultimately cause tooth loss. Increased tooth mobility may negatively affect masticatory function, aesthetics, and patient comfort. One of the treatment modalities used to stabilize mobile teeth is splinting. Splinting combined with occlusal adjustment is intended to reduce and control the progression of tooth mobility. Case Report: A 54-year-old female patient presented to Soelastri Dental Hospital with a chief complaint of mobility of the lower anterior teeth that had been present for approximately six months. The patient reported that the teeth felt loose during mastication, particularly when contacting the maxillary teeth. Intraoral examination revealed Grade 2 tooth mobility in teeth 32, 31, 41, and 42. Bleeding on probing was observed in the mandibular anterior region. Periodontal pocket depths around teeth 32, 31, 41, and 42 ranged from 5 to 6 mm. Radiographic examination demonstrated alveolar bone loss associated with these teeth. Management of this case involved the placement of a fiber-reinforced composite splint extending from teeth 33 to 43. Fiber splinting was selected because of its advantages, including high mechanical strength, excellent adhesive properties, biocompatibility, satisfactory esthetics, and ease of clinical application. Evaluation one week after splint placement showed favorable outcomes, with no signs of gingival inflammation or food impaction in the splinted area, as well as satisfactory occlusal relationships.

The Effect Of Educational Videos About Anemia On The Knowledge Of Pregnant Women In The Working Area Of Telaga Dewa Public Health Center, Bengkulu City

2026-06-19T00:28:04+00:00

Anemia in pregnant women remains a significant health problem that can increase the risk of complications for both mother and fetus. Low levels of knowledge among pregnant women are one of the contributing factors to the occurrence of anemia. Therefore, effective educational media are needed, one of which is video-based education. This study aimed to determine the effect of an educational video about anemia on improving the knowledge of pregnant women at Telaga Dewa Public Health Center, Bengkulu City. This study used a pre-experimental design with a one-group pretest-posttest approach. A total of 107 pregnant women were selected using purposive sampling technique. Data were collected using a questionnaire to measure the level of knowledge before and after the intervention. Data analysis was conducted using normality test and paired t-test. The results showed that before the intervention, most respondents had a moderate level of knowledge with a mean score of 21.03. After receiving education through video, all respondents were categorized as having good knowledge with the mean score increasing to 26.79.

2026-06-14T10:13:59+00:00

Stunting remains a serious nutritional challenge in Seram Bagian Timur (SBT) District, with a prevalence of 27.5% in 2023 — well above the national average. In response, the Gerakan Orang Tua Asuh Cegah Stunting (GENTING) program was socialized in SBT in January 2025, targeting 218 at-risk families across 15 sub-districts. This study aims to analyze the early implementation of the GENTING program in SBT District in 2025-2026 using an Input-Process-Output (IPO) framework. A descriptive quantitative approach was applied using secondary data, comprising the 2024 stunting-risk family recapitulation, field verification and validation (verval) results, and Orang Tua Asuh (OTA) distribution records as of June 9, 2026. Three key findings emerged: first, there were significant inconsistencies between planned targets and verval results across sub-districts, with deviations ranging from -75% to +460% of initial targets; second, OTA assistance coverage reached only 9.0% of 211 verified beneficiaries, with 7 sub-districts receiving no assistance at all; third, 95% of distributed aid consisted of nutritional support despite 24.6% of target families lacking adequate sanitation facilities, alongside inconsistencies in aid values, some falling below the national minimum standard of IDR 15,000 per day. It is concluded that the early implementation of GENTING in SBT faces three structural problems: data accuracy in planning, geographic disparity in aid distribution, and suboptimal matching of aid type to beneficiary risk profiles.

2026-07-01T10:06:01+00:00

Hospitalization can be a stressful experience for children, especially when they undergo invasive procedures, which often cause pain and anxiety, which can impact their physical and psychological well-being. This can lead to trauma during hospitalization. This study aimed to identify the relationship between parental involvement and pain and anxiety levels in preschool children during invasive procedures. This study used a quantitative approach and research’s design was a cross-sectional survey. A total of 52 children aged 3-6 years (preschool) with non-oncology cases were treated at the Private Hospital “X” in Medan with purposive sampling. The instruments in this study were questionnaires and pain scale observation. Bivariate test used the non-parametric Spearman's Rho test. The results showed that there was no significant relationship between parental involvement and preschool children's pain level during invasive procedures and there was a significant relationship between parental involvement and anxiety level of preschool children undergoing invasive procedures. Parents' inability to provide appropriate support has the potential to worsen the child's emotional condition, which in turn increases the risk of failure of the procedure, prolongs the duration of the procedure, and adds to the psychological burden on health workers. It is recommended that further researchers conduct intervention studies to identify parental involvement during hospitalization.

The Relationship Between Ultra-Processed Food Consumption And Obesity In Adolescent: A Narrative Review

2026-05-12T22:21:23+00:00

The rising global prevalence of obesity is a public health issue, with dietary factors increasingly recognized as root to its development. Ultra-processed foods (UPFs), a common modern diet, are characterized by high industrial processing with high energy density but poor in essential nutrients. This literature review aims to synthesize current evidence regarding the relationship between the consumption of UPFs and the incidence of obesity in adolescents. It investigates the consistency of this association, underlying mechanisms, and variations across populations. A systematic search was conducted using relevant keywords and search terms related to ultra-processed foods, food processing, obesity, weight gain, body mass index, and adolescents. Epidemiological studies employing diverse methodologies, including cohort and cross- sectional designs, consistently suggest a positive association between higher UPF intake and increased risk of overweight and obesity in adults and children. Potential mechanisms underlying this association are the energy density and palatability of UPFs, their impact on appetite and satiety, and their substitution for more nutrient-dense with minimal process. Strong evidence suggests UPF consumption is a significant risk factor for obesity development. Public health strategies should prioritize reducing ultra- processed food consumption via labeling, guidelines, and promotion of minimally processed foods, while further research strengthens causal inference and effective interventions.

Analysis Of The Effect Of Excess Air On Boiler Combustion Efficiency At PT PLN Nusantara Power Paiton Unit 9

2026-06-04T03:31:51+00:00

Boiler combustion efficiency is one of the important factors affecting the performance and operational reliability of steam power plants. One of the parameters that significantly influences combustion efficiency is excess air, which refers to the amount of air supplied exceeding the theoretical combustion requirement. This study aims to analyze the effect of excess air on boiler combustion efficiency at PT PLN Nusantara Power Paiton Unit 9. The research method used is a descriptive quantitative approach through field observations and operational data analysis obtained from the Distributed Control System (DCS). The analyzed parameters include oxygen content (O₂), excess air, boiler load, flue gas temperature, air flow, fuel flow, heat loss, and combustion efficiency. The results show that increasing excess air causes higher heat loss due to the increasing amount of heat carried away by flue gas, resulting in decreased boiler combustion efficiency. At low boiler loads, excess air tends to increase because the combustion process becomes less stable and requires additional air to maintain flame stability. Meanwhile, optimal excess air conditions provide more stable combustion, lower heat loss, and higher combustion efficiency. Therefore, controlling excess air properly is essential to maintain optimal boiler performance, improve operational efficiency, and reduce energy losses in the power generation system.

2026-06-17T22:51:27+00:00

The maintenance of cultural heritage buildings is gradually shifting from a curative approach toward preventive conservation supported by digital technologies. Although Heritage Building Information Modeling (HBIM) has been widely adopted, the resulting models are generally static and incapable of integrating real-time structural monitoring data. This study employs a qualitative case study approach combined with a literature review. The literature review was conducted to identify variables, subvariables, and indicators, which were subsequently validated by experts. In addition, benchmarking of previous frameworks was carried out to understand existing structures and methodologies. Based on these findings, a framework was developed according to the research requirements and further validated by experts to ensure its reliability and practical applicability. This study proposes a Digital Twin (DT) framework for cultural heritage buildings by integrating geometric building models, historical information, and dynamic data obtained from accelerometer sensors. The framework consists of four main layers: the information source layer, the BIM model layer, the integration layer, and the application layer for visualization and decision-making support. The framework was implemented in the Jakarta Cathedral to evaluate the integration of sensor data into the HBIM environment. Expert validation results indicate that the proposed framework provides a systematic approach to supporting preventive conservation for cultural heritage buildings with complex geometries.

Application Of Transportation Method In Optimizing The Cost Of Equal Distribution Of Zakat Fitrah In Ngaglik District, Sleman, Yogyakarta

2026-06-15T03:06:09+00:00

Zakat is a form of worship that can bring many benefits to Muslims, especially zakat fitrah. However, several problems remain frequently encountered in the implementation of zakat fitrah, one of which is the distribution of varying amounts of rice in each region. To address this issue, it is necessary to equalize the distribution of zakat fitrah. This can be achieved by distributing zakat fitrah to regions receiving more rice, especially those receiving less. To achieve this, it is necessary to find an effective method to make the distribution process more efficient. One method that can be used is transportation, which will make the allocation of goods more effective in terms of labor, time, and costs. In the case of zakat fitrah, each region acts as both a source and a destination. The source supply is based on the amount of zakat fitrah received, while the destination demand is based on the number of zakat recipients in each region. This study uses data from hamlets in Ngaglik sub-district, Sleman, Yogyakarta. The solution to the equitable distribution of zakat fitrah is solved using a transportation model with the North-West Center method, the Least Cost method, and the Vogel Approach Method (VAM) which is useful for analyzing initial feasibility. The minimum solution of the three methods is obtained by the Least Cost Method; Modified Distribution (MODI) to analyze the optimum solution. From the calculation of the transportation method, the optimum cost is obtained at Rp. 972,350.00; zakat fitrah recipients receive the same amount of 5.6 kg per head of family; and the determination of zakat fitrah delivery from one region to another.

The purpose of the study was to determine the magnitude of the tool life in dry machining of TEW 6582 steel with various cutting conditions. To study the tool life, 9 cutting conditions were first determined, namely cutting speed 200 m/min, 250 m/min, 300 m/min; feed 0.15 mm/r, 0.2 mm/r, 0.25 mm/r and cutting depth 1 mm, 1.5 mm, 2 mm. Edge wear (VB) 0.1 mm, 0.3 mm and 0.5 mm and measured using an optical microscope. Experimental data were processed and analyzed using the Taguchi L9 method (34). Cutting speed has a significant effect on tool life, where increasing cutting speed substantially reduces tool life. Depth of cut and feed rate also contribute to tool wear, although to a lesser extent than cutting speed. The results show that the optimum cutting conditions are obtained by dry machining at a cutting speed of 200 m/min, a depth of cut of 1.0 mm, a feed of 0.15 mm/r and a tool geometry of 6o. This cutting condition gives a tool life of 2.456 second (40.9 minutes). When this cutting condition is carried out with wet machining, it is found that the tool life is 2.591 second (43.1 minutes). So the difference in tool life between dry and wet machining is not significant so that dry machining is feasible for the manufacturing industry.

2026-06-24T01:07:34+00:00

Recurrent aphthosis stomatitis (SAR) is a common inflammatory condition of the oral cavity characterized by a round or oval ulcer with a yellowish-white color with erythema edges and occurs repeatedly. SARs can be classified into 3 types based on their number and size, namely minor SAR, major SAR, and herpetiform SAR. Factors that can cause SAR are in the form of hematology, genetics, immunology and hormonal. To determine the management of cases of Recurrent Aphthosal Stomatitis (SAR) et causa stress and nutritional deficiency through the KIE approach. A 23-year-old man came with a complaint of canker sores on the buccal mucosa of the right upper jaw. The patient complained of canker sores since 3 days ago and the complaints recur about once every 2-3 months. On intraoral examination, there was an oval-shaped ulceration, clearly bordered, white base and surrounded by erythema halo, measuring 3x2 mm on the buccal mucosa of the right upper jaw and symptomatic. Patients are given multivitamin supplements and focus more on the provision of Communication, Information and Education (KIE). Patients are given information about the triggering factors that can cause SAR, namely due to psychological stress. Patients are also given education about oral hygiene, increasing mineral water consumption, consuming vegetables and fruits and managing stress. An approach through Communication, Information and Education (KIE) and psychological support for SAR sufferers due to stress factors is more effective, such as directing patients to manage their stress management with a healthier lifestyle and diet to accelerate the healing process of lesions. If needed, patients can be referred to a psychologist/psychiatrist for psychological support.

2026-06-21T02:12:56+00:00

To date, merchants and consumers in both traditional and modern markets generally still rely on direct visual observation to determine fruit freshness, a method that is highly subjective and often inconsistent. Deep Learning (DL) offers a relevant automation solution to this problem. This study applies a custom Sequential Convolutional Neural Network (CNN) architecture to simultaneously classify the type and freshness level of apples, bananas, and oranges into six classes. Using a Research and Development (R&D) approach, the model was trained on 8,400 images from Kaggle, divided into 80% training, 10% validation, and 10% testing data. The architecture consists of five convolutional layers (32 to 512 filters), reinforced with a 0.5 dropout rate and an EarlyStopping mechanism to prevent overfitting. The model achieved a test accuracy of 98.92% with a loss value of 0.1404. The trained model was integrated into a web application named "Know Your Fruits" using the Flask framework. Black Box Testing on 30 independent images from the internet showed that the application could adaptively predict fruit freshness across various backgrounds, with a misprediction rate of 6.67% caused by early-stage decay and geometric distortion from advanced rotting.
