Breastfeeding should ideally begin immediately after birth and be provided exclusively for the first six months of life. However, in 2022, the coverage of exclusive breastfeeding among infants aged 0–6 months in Jayapura was only 21%, which remains far below the national target of 45%. Various factors contribute to this low coverage, including limited knowledge, lack of experience, insufficient support systems, and concerns among adolescent mothers that breastfeeding may interfere with their education or employment. This study aimed to explore the breastfeeding experiences of adolescent mothers in Wahno Village, Abepura Subdistrict. A qualitative research design was used, with structured interviews conducted using a questionnaire. The results indicated that the initiation of exclusive breastfeeding among adolescent mothers was generally positive. Participants reported mixed emotional experiences, including feelings of happiness, pride, stress, and discomfort. Family support, particularly from husbands, played an important role in sustaining breastfeeding practices. Most respondents also demonstrated adequate knowledge regarding how to manage breastfeeding-related challenges. Overall, adolescent mothers in Wahno Village showed a reasonable level of understanding and commitment toward exclusive breastfeeding. Continued education and support are recommended to further strengthen breastfeeding practices among adolescent mothers and their families.

This study aims to analyze the management of young preacher (dai cilik) training in developing students’ preaching skills at SD IT Al-Washliyah Kelambir Lima Medan using a management function approach (*planning, organizing, actuating, and controlling*). This study employed a descriptive qualitative method, with data collected through in-depth interviews, participant observation, and documentation. The research informants consisted of the principal and teachers responsible for the young preacher training program. The collected data were analyzed systematically to describe the implementation of management functions in the young preacher training activities and their contribution to the development of students’ preaching skills. The results showed that planning was carried out through the development of a practice-based preaching curriculum, organizing was implemented through task allocation and regular scheduling, implementation focused on *public speaking* practice, sermon material preparation, and moral development, while evaluation was conducted periodically through student performance assessments. The implementation of this systematic training management contributed to the improvement of students’ preaching skills in cognitive, affective, and psychomotor aspects. These findings indicate that management functions applied in a structured manner play a strategic role in supporting the development of students’ preaching competencies at the elementary school level. Furthermore, continuous training provides opportunities for students to enhance their self-confidence, communication skills, and readiness to effectively deliver Islamic preaching messages

Various viruses due to unhygienic surfaces of eating and drinking utensils, especially those that are frequently used and repeated, if they do not meet health standards have the potential to cause disease in subsequent users as a problem faced. The purpose of fabrication is to obtain eating and drinking utensils (talam-ompreng) measuring 400x300x0.4 mm made of SS304 which are hygienic, practical, heat resistant, not easily broken, not easily worn, easy to wash and easy to carry. The fabrication method includes: design of a 40 cm long, 30 cm wide eating tray, 7 serial basins (rice container 12 x 12 cm 2 basins, side dish container 8 x 8 cm 3 basins, vegetable container 6 x 6 cm 1 basin, fruit container 6 x 6 cm 1 basin) with a depth of 30 mm, a thickness of 0.4 mm; selection of SS304 plates; design of pressing molds; checking the thickness of SS304 plates; cutting material 55 x 45 cm; pressing until flat (not bulging or thinning/torn); bending the edges around; finishing cleaning metal thorns; stamping according to order; and quality inspection of the ompreng tray according to nutritional standards. The fabrication results in a 40 cm long, 30 cm wide, 0.4 mm thick tray made of SS304 material with a total production cost of IDR 75,000/unit, and a process duration of 2 minutes/unit which implies that the eating and drinking utensils can be used repeatedly after being washed clean from viruses.

Environmental-based diseases remain a major public health issue associated with unsafe drinking water, inadequate sanitation, poor hygiene behavior, improper household waste management, and unsafe domestic wastewater disposal. Community-Based Total Sanitation, known in Indonesia as Sanitasi Total Berbasis Masyarakat or STBM, is a community empowerment approach designed to change hygiene and sanitation behavior through five pillars. This article aims to develop an STBM program planning design and an impact evaluation model for reducing environmental-based diseases, particularly diarrhoeal disease. This study used a narrative review method by analyzing national regulations, official guidelines, global WASH reports, and recent scientific literature. The proposed program design includes situation analysis, multisectoral advocacy, community triggering, household mentoring, strengthening sanitation facilities, monitoring, verification, and impact evaluation. The evaluation model uses process, output, outcome, and impact indicators, with diarrhoea incidence as the main measurable health indicator. The findings indicate that an integrated STBM program supported by community participation, valid baseline data, and periodic evaluation can strengthen the prevention of environmental-based diseases. This article recommends implementing STBM as a sustainable community-based public health intervention rather than a short-term sanitation activity. 

The use of synthetic dyes in the textile industry has caused various environmental problems due to waste that is difficult to degrade and has the potential to contaminate water and soil. Therefore, the development of environmentally friendly natural dyes is an important alternative to be explored. One potential but underutilized source of natural dye is kirinyuh weed (Chromolaena odorata L.), which is known to contain natural pigment compounds such as tannins and flavonoids. This study aims to analyze the dyeing quality of primissima cotton fabric using kirinyuh leaf extract with variations of alum and ferrous mordants through a mordanting process. The research employed an experimental method, including hot extraction of kirinyuh leaves, dyeing of primissima cotton fabric, and mordanting using alum and ferrous salts. The evaluation of dyeing quality focused on washing color fastness and light color fastness tests based on standard textile testing methods. The results indicate that the type of mordant significantly affects the resulting color quality. Alum mordant produced relatively lighter colors with good washing fastness, while ferrous mordant resulted in darker shades with similarly good washing fastness. However, color fastness to light showed relatively lower values, particularly in fabrics treated with alum mordant. Based on these findings, it can be concluded that kirinyuh leaf extract has the potential to be used as a natural dye for primissima cotton fabric, although further optimization is required to improve color resistance to light exposure.

This study aims to clarify the conceptual differences between measurement, assessment, and evaluation; present a comparative analysis of their characteristics; formulate concrete application examples across four Arabic language skills (istima', kalam, qira'ah, and kitabah) in madrasah; and analyze evaluation principles in creating an objective and fair assessment system. The study employs a library research method with a descriptive-analytical approach through content analysis of relevant academic sources. The findings indicate that measurement, assessment, and evaluation form a hierarchical and mutually reinforcing relationship, yet they differ in scope, function, and purpose. Measurement focuses on quantifying learning outcomes, assessment interprets those results, and evaluation provides overall judgment for decision-making. The current imbalance in Arabic language evaluation at madrasah, which often emphasizes cognitive measurement alone, can be improved through comprehensive assessment of all four language skills. This should be grounded in principles of validity, reliability, objectivity, practicality, and positive washback to ensure a fair, meaningful, and educationally sound evaluation system.  

Drowning is one of the leading causes of accidental death worldwide and remains a major challenge in forensic investigations due to the complexity of determining the exact cause and mechanism of death. This study aimed to analyze forensic investigation methods used to determine the cause of death in drowning cases. The research employed a qualitative descriptive literature review approach by analyzing scientific articles, forensic journals, and medical references related to drowning investigations. Data were collected through literature searches from Google Scholar, PubMed, and Portal Garuda using keywords related to forensic drowning investigations. The findings indicate that forensic investigation in drowning cases requires a comprehensive approach involving external examination, autopsy, laboratory examination, histopathology, diatom analysis, toxicology, and crime scene investigation. Typical forensic findings include foam cone, washerwoman’s hands, cutis anserina, emphysema aquosum, and the presence of foreign materials in the respiratory and digestive tracts. Diatom examination and histopathological analysis also play important roles in strengthening the diagnosis of drowning. The study concludes that an integrated forensic investigation based on scientific evidence is essential to accurately determine the cause and manner of death in drowning cases and to support medicolegal processes in Indonesia.

Clean and healthy living habits are an essential foundation in shaping a generation that is mindful of personal and environmental health. These habits need to be instilled from an early age, both at school and at home, so that they can become a sustainable part of students' lifestyles. This community service activity aims to improve the knowledge and skills of students at SD Negeri 1 Mertoyudan in consistently applying Clean and Healthy Living Behaviors (PHBS) in their daily lives. The implementation methods comprised three main approaches: interactive discussion-based education, a demonstration of proper handwashing techniques in accordance with WHO standards, and hands-on practice in maintaining personal hygiene. These approaches were chosen to ensure that students not only understand the concept of PHBS theoretically but are also able to apply it independently in real-life situations. The results of the activity showed a significant improvement in students' understanding of the importance of washing hands with soap at critical moments as a form of personal hygiene responsibility. Through a demonstrative approach that involved active student participation, participants were able to practice proper personal hygiene steps accurately and confidently. This activity is hoped to have a long-term impact in shaping students who are disciplined, responsible, and attentive to both personal and environmental health, while also serving as an effective preventive measure in reducing the risk of infectious diseases among school-age children.

Clean water availability is an essential component of hospital hygiene and sanitation operations, including hand hygiene, environmental cleaning, linen management, food sanitation, and infection prevention. RSUD Sumbersari Bantul Metro Selatan still relies on one bore well and has limited water storage without a permanent backup source. This study aimed to analyze the adequacy of clean water quantity and quality in supporting hygiene and sanitation operations at RSUD Sumbersari Bantul Metro Selatan in 2026. This study used a descriptive analytic design. Data were collected through observation, interviews, water discharge and consumption measurement, document review, and laboratory examination of clean water samples. The analysis compared water availability, water demand, unit-based distribution needs, and water quality with the standards of Ministry of Health Regulation Number 2 of 2023. The results showed that during January-March 2026, the hospital served 154 inpatients and 1,028 outpatients and had 151 staff members. The total clean water requirement was 715.44 m3/90 days, while the available water was only 414.00 m3/90 days, fulfilling 57.87% of the required amount. The average daily need was 7.95 m3/day, compared with the availability of 4.60 m3/day. High-risk service units, particularly inpatient care, emergency services, intensive care, CSSD, isolation, maternity care, laundry, and nutrition services, require priority water distribution. Laboratory testing found Escherichia coli and total coliform at 19 CFU/100 ml each, exceeding the required standard of 0 CFU/100 ml. In conclusion, the quantity and microbiological quality of clean water at RSUD Sumbersari Bantul have not adequately supported optimal hygiene and sanitation operations.

Modern urban churches, specifically Gereja Bethel Indonesia (GBI) PRJ Jakarta, face challenges in bridging the intergenerational gap in leadership regeneration. This research aims to reformulate the paradigm of church leadership towards the next generation by exploring the theological meaning of Jesus' act of washing His disciples' feet based on the text of John 13:12-17. Using a qualitative method through a library research approach as well as textual and contextual biblical analysis, this study deconstructs the concept of worldly elitist power into a servant leadership model. The results of the expository analysis show that Jesus validated His historical and political authority not through social status distance, but through incarnational ministry, relational proximity, and role modeling. As a practical implication for the quality of ministry at GBI PRJ Jakarta, these findings recommend a strategic transition from a one-way communication leadership style to relational mentoring, the empowerment of the younger generation through the delegation of authority, and the tangible modeling of integrity. In conclusion, the improvement of shared ministry quality highly depends on the willingness of church leaders to lay aside structural egos and disciple the younger generation through the example of humility centered on the work of the cross of Christ.

Vegetables are food commodities widely consumed by the public due to their high nutritional content. Chili (Capsicum annuum L.), green beans (Phaseolus vulgaris L.), and Chinese cabbage (Brassica pekinensia L.) are among the vegetables that can be processed into various delicious dishes or consumed fresh as raw vegetables. To obtain healthy and high-quality vegetable crops, pesticides are commonly used to control pests that may damage the plants. One of the widely used pesticides is chlorpyrifos, which can leave residues that may pose both acute and chronic health risks. Therefore, it is necessary to analyze the levels of chlorpyrifos pesticide residues in vegetables. The residue levels were determined using a UV-Vis spectrophotometer at a wavelength of 230 nm with dichloromethane as the solvent, while qualitative analysis was performed using HPLC by comparing the retention times of standard solutions and vegetable samples. In this study, washing treatments were applied to the vegetables using dichloromethane, distilled water, well water, and tap water (PDAM) to evaluate the effect of washing on pesticide residue levels. The concentrations of pesticide residues in unwashed vegetables were chili (2.6680 ± 0.0214 mg/kg), green beans (2.4658 ± 0.0193 mg/kg), and Chinese cabbage (2.7950 ± 0.0379 mg/kg). The washing process was carried out three times for each solvent. After three washings using dichloromethane and distilled water, pesticide residues were no longer detected, whereas washing with tap water (PDAM) and well water still left residues, although at levels much lower than the Maximum Residue Limit (MRL). The health risk assessment showed that the aHQ and cHQ values were < 1, indicating that consumption within the recommended limits of these samples does not pose health risks, either in the short term or long term. This study provides important information that repeated washing is necessary to effectively reduce pesticide residue levels in vegetables before consumption.  

Chili (Capsicum annuum L) ) is one of the most important horticultural commodities widely consumed in Indonesia and has high economic value. To maintain productivity and prevent pest attacks, farmers commonly apply chemical pesticides intensively. However, excessive and improper pesticide application can leave harmful residues on the surface and within the tissues of chili fruits. The accumulation of these residues not only poses health risks to consumers but also contributes to environmental pollution, particularly in wastewater generated from chili washing activities. This study aims to reduce pesticide residues of Cherizeb and Emacel in chili washing water using the photolysis methodassisted by a ZnO/zeolite catalyst. Zinc oxide (ZnO) acts as a photocatalyst activated by ultraviolet (UV) light to produce reactive hydroxyl radicals (•OH) capable of decomposing complex organic compounds into simpler compounds such as CO₂ and H₂O. Meanwhile, zeolite is used as a catalyst support due to its large surface area and high adsorption capacity, allowing adsorption and photocatalytic processes to occur simultaneously. The results showed that the photolysis method using the ZnO/zeolite catalyst significantly reduced pesticide residues, with optimum degradation efficiencies of 85.66% for Cherizeb using 0.8 g ZnO/zeolite under UV irradiation for 60 minutes, and 83.97% for Emacel using 0.8 g ZnO/zeolite under UV irradiation for 75 minutes. The samples were characterized using Fourier Transform Infrared Spectroscopy (FTIR) to identify functional groups, indicating the disappearance of specific organic functional groups. Pesticide residues on chili samples were analyzed using UV-Vis spectrophotometry to determine concentrations before and after treatment. X-Ray Diffraction (XRD) analysis confirmed that the crystalline structure of the catalyst remained stable after the photolysis process. Based on these findings, the ZnO/zeolite catalyst is proven to be effective in reducing pesticide residues through photocatalytic degradation and has the potential to be applied as a safe, efficient, and environmentally friendly post-harvest technology to improve the quality of agricultural products.

This qualitative literature review investigates how tax scrutiny influences investor behavior in the cryptocurrency market, with a focus on tax-loss harvesting and wash trading strategies. As governments enhance transparency and enforcement, crypto investors increasingly adapt their behaviors to optimize after-tax outcomes. The review synthesizes recent academic findings that highlight the growing use of legal tax-loss harvesting and the controversial persistence of wash trading, particularly in unregulated exchanges. Evidence suggests that regulatory uncertainty and inconsistent tax treatment across jurisdictions drive strategic investor responses and, in some cases, unintended compliance gaps. This study underscores the need for updated tax frameworks capable of addressing the unique characteristics of digital assets. The analysis contributes to the broader discourse on how taxation shapes market behavior in emerging financial ecosystems

The implementation of Clean and Healthy Living Behavior (PHBS) begins at an early age, particularly among school children, who learn extensively from their surrounding environment through the School Health Program (UKS). Although the family is the primary unit in shaping PHBS habits, parents’ busy schedules often lead children to interact more with teachers and peers at school. This study aims to determine the effectiveness of the UKS program on students’ PHBS at SD Lambaro Angan, Darussalam District, Aceh Besar Regency in 2024. This research employed a cross-sectional design with a population of 321 students and a sample of 76 respondents. Data collection was conducted on March 4, 2024. The results indicate that the UKS program has a significant effect on students’ PHBS, including habits such as washing hands with running water and soap, purchasing healthy snacks at the school canteen, disposing of waste properly, participating in physical exercise, not smoking at school, eliminating mosquito larvae, and using school sanitation facilities (p < 0.05). However, no significant effect was found on activities such as weighing body weight and measuring height. In conclusion, the UKS program is effective in improving students’ PHBS. These findings are expected to provide input for schools to optimize the implementation of UKS and enhance PHBS promotion so that students can apply clean and healthy living behaviors in their daily lives.

Typhoid fever is an infectious disease caused by Salmonella typhi. Transmission can occur through air or food contaminated with the urine and feces of typhoid sufferers, such as air used for drinking, cooking, and washing food. Symptoms of typhoid fever include a prolonged high fever, defined as an elevated body temperature of >37.5°C. Other symptoms can include fatigue, nausea, abdominal pain, constipation or diarrhea, and headache. This study aimed to treat children with typhoid fever. The method used was a case study of a five-year-old child with typhoid fever who was hospitalized for four days. The results showed that the child had fever, obesity, and decreased appetite. The child's problem was hypothermia, while cooling interventions were used to manage hypothermia, and one of the cooling procedures performed was the application of aloe vera compresses. The evaluation results showed that the hyperthermia resolved after four days of hospitalization. Based on this study, it is hoped that patients and their families can independently apply aloe vera compresses to treat hypothermia in children.

PT UVW uses jigs in the vacuum metalizing process that require washing, which is currently done manually, resulting in inefficiency and risks to operators, thus, jig washer machine was created in order to reduce the risk for operators and increasing efficiency, which based on horizontal mixer. This study analyses the effect of agitator design on fluid flow patterns in a jig washing machine to obtain an optimal design. Two agitator design alternatives were developed and tested using Computational Fluid Dynamics (CFD) simulations at rotational speeds of 70, 75, and 100 rpm, followed by prototype fabrication and performance testing. Simulation results show that the second design produces a higher fluid velocity (20.4 m/s) and a more turbulent and uniform flow pattern compared to the first design (1.7 m/s). Field tests confirmed that the second design achieves higher washing effectiveness (97.14%) with reduced water consumption and shorter washing time. The optimally designed agitator washing machine increases productivity by six times compared to manual washing and reduces operator exposure to hazardous chemicals. This study recommends the second agitator design for improving washing efficiency and effectiveness.

Hand washing is a major pillar in clean and healthy living behaviors (PHBS). However, there are still children who do not understand the correct handwashing technique so that germ cleaning is not optimal. This community service activity aims to improve students' knowledge and motor skills in practicing the six steps of hand washing according to World Health Organization (WHO) standards. The method used in this activity is interactive counseling combined with live demonstrations. The stages of the activity include providing material through audiovisual media (video/poster), direct demonstrations by instructors, and independent practice by all participants. In addition, a question and answer session was held to ensure student understanding and corrective feedback on inappropriate movements. Evaluation instruments in the form of observation sheets were used to assess the accuracy of the sequence, duration, and coverage of the hand area when washing. The result of this activity was the success of all participants in practicing the six-step sequence of handwashing correctly independently. The involvement of teachers and school health workers also strengthens the sustainability of this practice through regular monitoring. Through this education, it is hoped that early awareness will arise which has become a routine habit to reduce the risk of disease transmission in the school and home environment and support the creation of a culture of clean living from an early age.

This study aims to describe dietary patterns, food consumption habits, hygiene awareness, and environmental and social factors related to digestive disorders in junior high school students. This study used a descriptive approach with a closed-ended interview method (Yes/No answers) with Thirty-five  junior high school students using 15 questions. The results showed that some students did not have consistent breakfast habits, had a high tendency to consume fried foods and sugary drinks, and demonstrated low awareness of food safety and hygiene habits such as washing hands before eating. In addition, the school environment, peer influence, and psychological well-being influence students’ eating patterns. These factors contribute to digestive problems in some students. Therefore, schools must actively participate in maintaining a clean environment, providing students with healthy food options, and providing ongoing nutritional instruction on digestive health.

The increasing need for insulation in electric power systems encourages the discovery of high-performance and sustainable dielectric materials. This study presents a Literature Review of biomass-based composite insulator research from 2018-2025 to synthesize the effect of filler type and treatment on the electrical, thermal, and mechanical properties of polymer composites. Literature was analyzed from reputable databases with inclusion criteria, and thematic analysis data extraction. Processing methods generally include washing, acid/alkali treatment, calcination, and advanced production techniques such as sol-gel and ultrasonication, integration of biomass fillers especially at low fractions (3-7%). The results show 1) the dominance of the use of rice husk as a source of biosilica for the main matrix filler of the insulator. 2) the performance of biomass composite insulators is highly dependent on the quality of purification, particle size, and surface modification of the filler. 3) there is a significant increase in the insulator's breakdown strength, resistivity, and thermal stability with the addition of biomass fillers to the main matrix. 4) the long-term stability of biomass materials against humidity and thermal aging has not been evaluated in depth.  

This community service programme was implemented in the coastal community of Padelegan Village, Pademawu Subdistrict, Pamekasan Regency, with a focus on strengthening health literacy and behaviour-based disease prevention at the household level. The background of the activity is based on the vulnerability of coastal communities to health problems related to hygiene, household drinking water management, and environmental cleanliness, as well as the need for an approach that not only increases knowledge but also encourages consistent preventive practices. The programme aims to improve residents' ability to understand and use health information in an applicable manner, while strengthening key disease prevention behaviours through education and mentoring. The activity will be carried out from February to April 2025 with a behaviour-based education design combined with practice demonstrations and community mentoring, involving 48 participants (40 residents/households and 8 posyandu/PKK cadres). The stages included initial assessment, development of KIE media (brief modules and leaflets/posters), two education-demonstration sessions, two home mentoring sessions, and final evaluation. The evaluation was conducted using pre-post knowledge, attitude, and practice (KAP) assessments and practice observation through a checklist. The results showed an increase in health literacy and improved consistency in preventive behaviour; knowledge increased from 5.4 to 7.8, and compliance with hand washing at critical times increased from 41.7% to 72.9%. Programme outputs included an information, education and communication (IEC) package, a household monitoring checklist, and capacity building for cadres as local facilitators. It was concluded that the integration of participatory education, practical demonstrations and cadre mentoring has the potential to be effective in encouraging preventive behavioural change in coastal communities, with recommendations for integrating monitoring into the routine agenda of integrated health service posts (posyandu) and community empowerment groups (PKK) and for follow-up monitoring for 3–6 months to maintain the sustainability of practices.
