This study aims to formulate an engineering strategy for water quality management and pollution control in the Tiku Sub-watershed, North Musi Rawas Regency. The study used a descriptive approach by integrating selected technical data from a dissertation-based assessment with semi-structured interviews involving 20 key informants representing technical agencies, village and subdistrict governments, community leaders, artisanal and small-scale gold mining actors, farmers, and riverbank communities. The analysis focused on water quality status, water availability and demand, pollution sources, perceived impacts, implementation constraints, and priority interventions. The results showed that the Tiku Sub-watershed is under significant environmental pressure. The average pollution index was 6.65, indicating a moderately polluted status, while mercury, cadmium, phosphate, and ammonia were the dominant parameters of concern. Surface water availability remained relatively adequate at 45,842,699.79 m3/year, and the average Criticality Ratio was 0.266; however, the water pollution carrying capacity was poor. Interview results indicated that mercury use and processing waste from artisanal gold mining were the most urgent issue (35%), followed by land-cover change and riparian degradation. The recommended strategy combines mercury-free processing technology, alternative livelihood development, cross-sectoral supervision, riparian rehabilitation, and transparent water-quality monitoring. The findings imply that watershed engineering should integrate technical, institutional, and socio-economic interventions.

Plastic waste, particularly plastic bottles, has become one of the major challenges in urban environmental management due to its increasing volume and potential to pollute ecosystems. In Bogor City, plastic waste constitutes a significant proportion of daily municipal solid waste, highlighting the need for effective and sustainable waste management models. This study aims to analyze the role of the Reduce, Reuse, Recycle Waste Processing Facility (TPS3R) in managing plastic bottle waste in Bogor City, with a case study of the Eco Techno Park at Ibn Khaldun University (UIKA) Bogor. The research employed a descriptive qualitative method using a case study approach. Data were collected through field observations, in-depth interviews with facility managers, and reviews of relevant documents and literature. The findings indicate that the TPS3R Eco Techno Park has successfully implemented the 3R principles through an integrated system supported by environmentally friendly technologies and a circular economy framework. Plastic bottle waste is managed through sorting, shredding, and recycling processes to produce value-added products, including plastic pellets, handicrafts, and construction materials. In addition, organic waste management is integrated through the cultivation of Black Soldier Fly (BSF) larvae. The facility has contributed to reducing the volume of waste sent to landfills by approximately 18%. The study implies that strengthening regulatory support, enhancing community participation, and developing circular economy-based business models are essential to ensure the long-term sustainability of waste management programs and support Bogor City's waste reduction targets.

Primary healthcare centers generate both medical and non-medical waste that may pose environmental and public health risks if not properly managed. This study aims to describe the waste management practices at Kesumadadi Public Health Center, Bekri Subdistrict, Central Lampung Regency, in 2025. This research employed a descriptive design conducted in May 2025 at the Kesumadadi Public Health Center. Data were collected through observation and interviews as primary data and secondary data from the health center. Data processing included editing, coding, tabulating, and cleaning, while data analysis was carried out using checklists and questionnaires. The results showed that the segregation of medical and non-medical solid waste was not fully in accordance with standards, waste transportation to temporary storage areas did not use trolleys and lacked designated routes, there was no wastewater treatment facility for liquid waste, and the use of personal protective equipment by staff was not optimal. Waste management practices at the Kesumadadi Public Health Center have not met the required standards, particularly in waste segregation, transportation, liquid waste treatment, and occupational safety, therefore improvements are needed to reduce environmental and health risks.

Background: The prevalence of Chronic Energy Deficiency (SEZ) of pregnant women nationally is still 16.9%, and anemia reaches 27.7%, so the development of local food-based Supplementary Feeding (PMT) is needed. Brownies with the substitution of red spinach as a source of iron and purple sweet potato flour as an energy source have the potential to be developed as an alternative to PMT. This study aims to determine the acceptability and nutritional content of red spinach brownies with the addition of purple sweet potato flour as an interlude food for pregnant women. Method: Design using the Complete Random Design (RAL) method. The formulation of making brownies consists of three treatments with a comparison between (red spinach pureee and purple sweet potato flour) as follows: F1 (50:50), F2 (60:40), and F3 (40:60). The acceptance test was conducted using a hedonic test of color, aroma, taste, and texture on 30 semi-trained panelists. Analysis of nutritional content includes moisture content (thermogravimetry), ash content (dry ashing), protein (Kjeldahl), fat (Soxhlet), carbohydrates (by difference), and Fe (Atomic Absorption Spectrophotometry). The data were analyzed using the Kruskal-Wallis test. Research Results: The acceptability test showed that there was no significant difference between the formulations. The F3 formulation with a ratio of 40% red spinach pureee and 60% purple sweet potato flour obtained the highest preference value and was determined as the best formulation. The nutritional content of the F3 formulation includes protein 10.447%, fat 8.047%, carbohydrates 1.5579%, Fe 0.0005%, moisture content 20.68%, and ash content 1.4875%. Conclusion: There was no significant effect of each formulation on the acceptability of Brownis Suggestion: It is hoped that the next researcher can improve product formulation and processing processes to maintain and increase iron (Fe) levels in brownies.

The digital era has fundamentally revolutionized human interaction and information processing, particularly for Generation Z as digital natives. This research aims to identify the characteristics of digital information consumed by Generation Z and evaluate their long-term memory (LTM) capacity in the digital age. Using a Systematic Literature Review (SLR) method with a qualitative approach, 15 relevant studies published between 2021 and 2026 were analyzed from databases such as Scopus, Google Scholar, and ScienceDirect. The findings indicate that digital information characteristics—which are often "bite-sized," visual, and rapidly consumed—tend to encourage shallow encoding and digital amnesia. However, the study also found a dual impact: while high cognitive load and constant multitasking can hinder memory consolidation, structured digital use and interactive learning modules can significantly enhance memory retention. These results imply that optimal cognitive function in the digital era highly depends on digital literacy and effective information management strategies to balance technological use with natural cognitive sharpness.

Management of hazardous and toxic waste (B3) in hospitals is an important aspect of maintaining environmental health and preventing pollution risks. RSUD Jenderal Ahmad Yani Metro has implemented hazardous waste management using the reduce, reuse, recycle (3R) concept; however, its implementation has never been comprehensively evaluated. This study aimed to evaluate the management of hazardous waste using the 3R concept at RSUD Jenderal Ahmad Yani Metro based on the Regulation of the Minister of Environment and Forestry No. P.56/Menlhk-Setjen/2015 and to identify the supporting factors. This research used a qualitative design with a case study approach. The research informants consisted of 23 participants selected using purposive sampling, including the hospital director, ward heads, IPCN, sanitation officers, 3R waste management officers, and sanitation operators. Data were collected through observation, in-depth interviews, and document review using interview guidelines and checklists. Data analysis was conducted using the Miles and Huberman model, including data reduction, data display, and conclusion drawing. The results showed that the transportation, storage, and processing stages of hazardous waste management were in accordance with the Regulation of the Minister of Environment and Forestry No. P.56/Menlhk-Setjen/2015. However, the sorting and containerization processes were not fully compliant because recyclable waste was still mixed with other hazardous waste. In addition, several supporting factors were identified, including the lack of training and certification among human resources, inadequate infrastructure, and the absence of technical guidelines and standard operating procedures for the 3R waste bank. Therefore, improving human resource capacity, infrastructure, and internal hospital regulations is necessary to optimize 3R-based hazardous waste management.

The production of breast milk is essential for promoting optimal growth and developmental outcomes in infants throughout the first six months of life. Nevertheless, several studies have indicated that some breastfeeding mothers face challenges in producing adequate milk, often influenced by nutritional status, psychological conditions, and environmental support. The katuk plant (Sauropus androgynus), a well-known local herb, has long been recognized for its potential as a natural galactagogue that can stimulate breast milk production. The innovation of processing katuk leaf extract into biscuits offers a more practical, convenient, and potentially acceptable alternative for daily consumption among the community. The present study aimed to examine the impact of katuk leaf biscuits on breast milk production among breastfeeding mothers within the jurisdiction of Kuta Baro Health Center, Aceh Besar District. A pre-experimental design utilizing a one-group pretest–posttest method was implemented, involving 20 breastfeeding mothers who fulfilled the established inclusion criteria. Data collection was carried out through the administration of questionnaires and by measuring breast milk volume using a calibrated measuring cup.The study findings indicated that before the intervention, most participants had relatively low breast milk production, averaging 69.1 ml. After a seven-day intervention, the mean breast milk volume showed a significant increase to 246.5 ml, with a p-value of 0.000 (p < 0.05), the findings indicate that katuk leaf biscuits exert a significant influence on increasing breast milk production. Overall, this study underscores the potential of locally sourced, herbal-based food innovations as an effective and sustainable approach to enhancing breast milk production and supporting the success of exclusive breastfeeding programs.

This study investigates the strategic strengthening of the rambak cracker industry as an instrument for local economic development in Penanggulan Village, Pegandon District, Kendal Regency. Rural agro-processing enterprises have increasingly been recognized as territorially embedded production units capable of generating value-added outputs and absorbing surplus labor within localized economic systems. Field-based empirical observations reveal that rambak production in the village operates through household-managed processing systems characterized by traditional production techniques, informal managerial practices, and limited digital marketing adoption despite contributing significantly to community income generation. Data obtained from expert respondents were analyzed using the Analytical Hierarchy Process to identify strategic priority determinants influencing industrial competitiveness and sustainability. The results indicate that product innovation and quality improvement constitute the primary strategic priority, followed by digital marketing development and institutional partnership strengthening, while production capacity expansion remains comparatively less influential in enhancing market competitiveness. These findings suggest that adaptive innovation and digitally enabled commercialization pathways function as critical mechanisms for improving value-chain integration and expanding market accessibility among rural food-processing industries. Strengthening innovation ecosystems within the rambak sector may therefore contribute to employment creation, income diversification, and sustainable community-based economic transformation in rural production clusters.

The incidence of degenerative diseases, which are part of Non-Communicable Diseases (NCDs), remains a major cause of death worldwide and in many regions of Indonesia. Meanwhile, efforts to prevent degenerative diseases affecting the adolescent age group are still rare, such as the establishment of a Youth Posyandu, including in Sungai Duren Village. There is no health post that provides youth care services in Sungai Duren Village, while there are many teenagers living there (students under 21 years old) with various lifestyles that are at risk of degenerative diseases. This study aims to analyze the increase in adolescent knowledge about CERDIK between before and after the establishment of the Youth Posyandu in order to prevent degenerative diseases early. This study is a quasi-experimental study involving 30 adolescents by measuring the dependent variable of knowledge. The research instrument used is a questionnaire. Computerized data processing and analysis were conducted through descriptive statistical analysis and T-test analysis. The results showed a significant difference in respondents' knowledge of CERDIK before and after the establishment of the Youth Posyandu in Sungai Duren Village (p=0.000). This study indicates that structured health education can improve adolescents' understanding of CERDIK and can be used as an effective promotive and preventive strategy.

The formulated Gnocchi made from sweet potato flour exhibited color, aroma, taste, and texture characteristics that were well-received by panelists. Nutritional analysis conducted by the Industrial Research and Standardization Center of Manado revealed that sweet potato Gnocchi contains 55 g of moisture, 28 g of carbohydrates, 6 g of sugar, 3 g of dietary fiber, 2.5 g of protein, 1.2 g of total fat, and 200–300 mg of natural anthocyanins per 100 g. These components indicate that the product has the potential to be developed as a functional food. This study concludes that sweet potatoes have great potential to be developed as raw material for modern pasta products such as Gnocchi due to their favorable physical and chemical properties. In addition, the utilization of local ingredients supports national food diversification efforts, the development of creative culinary industries, and business opportunities for ready-to-cook and ready-to-eat food products.

Refill Drinking Water Depots (DAMIU) are businesses that provide ready-to-drink drinking water through raw water processing using simple and modern technology. The existence of DAMIU is very important in meeting the community's need for drinking water, but aspects of sanitation hygiene and water quality must remain a primary concern to avoid health risks. This study aims to describe the sanitation hygiene conditions and assess the microbiological quality of refill drinking water at DAMIU in the Indralaya Community Health Center working area in 2025. The study used a descriptive method with a laboratory approach to 27 refill drinking water depots. Data were collected through observations of location conditions, buildings, equipment, and handler hygiene, and laboratory examinations were conducted on raw water and processed water samples. The results showed that the majority of depots (92%) had met the requirements related to location and buildings, while all depots (100%) met the standards for processing equipment. However, drinking water handlers still did not comply with applicable hygiene standards (100%). Only 70% of depots had suitable raw water sources, with 55% using the Sukomoro source, 41% using drilled wells, and 4% using the Dewa Air Prabumulih source. Laboratory tests found that two depots (8%) had raw water that tested positive for Escherichia coli, but all treated water samples met established microbiological standards. Overall, this study concluded that the location, building, and equipment of the Drinking Water Supply Unit (DAMIU) in the Indralaya Community Health Center (Puskesmas) area were satisfactory, but handler hygiene remained a weakness that needed immediate improvement. Furthermore, the physical and chemical quality of the water still required attention, although the microbiological quality met standards.  

Financial management in hospitals is a crucial aspect to ensure the sustainability of quality health services. However, the complexity of financial data, which involves various budget components, often creates challenges for hospital management in conducting accurate analysis and budget planning. Therefore, a data-driven approach is required to present financial information in a structured and comprehensible manner. This study examines the application of the K-Means Clustering method to classify hospital financial data based on expenditure characteristics and patterns, with a case study at RSUD Rantau Prapat as part of a community service program. The financial data were analyzed through pre-processing stages, determination of the optimal number of clusters using the Elbow Method, and the implementation of the K-Means algorithm to generate more representative budget groups. The results indicate that clustering hospital financial data into three main categories—routine operational costs, medical service costs, and administrative/personnel costs—provides clearer insights into budget distribution. This supports hospital management in identifying budget allocation priorities, detecting potential inefficiencies, and improving the overall efficiency of financial governance. The limitation of this study lies in the data scope, which only involved a single hospital, thus restricting its generalizability. Future research is recommended to expand the scope to multiple hospitals and integrate alternative clustering methods to obtain more comprehensive results.
