Vegetables are an important horticultural commodity in fulfilling community nutritional needs; however, their consumption level in Indonesia remains relatively low, necessitating efforts to increase production. Spinach (Amaranthus sp.) is a promising vegetable due to its short growth cycle, ease of cultivation, and high nutritional value. Limited agricultural land, particularly in urban areas, poses a major constraint to conventional cultivation, thereby encouraging the adoption of alternative technologies such as hydroponics. The hydroponic system, especially the Nutrient Film Technique (NFT), offers efficient use of land and water while enabling better control of plant growth. This review aims to identify hydroponic cultivation techniques for spinach in greenhouse conditions and to analyze factors influencing its success, including nutrient concentration, growing media, pH, temperature, and light intensity. The findings indicate that optimal nutrient concentration ranges from 410–900 ppm, supported by proper environmental and pH management to enhance vegetative growth. The implementation of the NFT system improves production efficiency, resulting in more uniform, cleaner, and higher-quality yields. Nevertheless, challenges remain, including nutrient management, environmental fluctuations, and pest and disease risks. Therefore, proper and sustainable system management is essential to ensure successful hydroponic spinach cultivation.

Family health is a fundamental component of public health development, as the family represents the smallest social unit shaping individual health behaviors. This study aimed to analyze the family health conditions of the community in Pulau Jambu Village, Kampar District, based on demographic, behavioral, socioeconomic, and environmental factors. A descriptive quantitative approach was employed with a total sample of 153 respondents selected using random sampling, ensuring equal probability for each population member to be included.The results indicated that most respondents were in the productive age group of 19–60 years (68.8%), with farming as the dominant occupation (47.1%). The majority relied on borehole wells as their water source (61.4%); however, 47.1% had septic tank distances ≤10 meters, posing potential risks of water contamination. Regular physical activity was reported by 60.8% of respondents, yet the prevalence of smoking was very high (78.4%). Most respondents had a junior high school education (45.1%), influencing health literacy levels, although 58.2% demonstrated good knowledge of clean and healthy living behavior (PHBS). Health service utilization was relatively high (86.3%), though some residents still practiced traditional treatment.In conclusion, family health conditions are influenced by a combination of behavioral, environmental sanitation, and socioeconomic factors. Strengthening family-based health interventions through PHBS education, smoking control, and environmental sanitation improvement is essential to enhance sustainable community health status.

The problem addressed in this research is the suboptimal implementation of the Community-Based Drinking Water Supply and Sanitation Program (PAMSIMAS) in Koili Village. The objective of this research is to analyze the implementation of the PAMSIMAS Program based on Donald P. Warwick’s policy implementation theory, which includes organizational capacity, information, support, and the distribution of potential resources. This research employs a descriptive qualitative method. Data were collected through interviews, observations, and documentation involving informants from the local government, village officials, PAMSIMAS management, and community members, both beneficiaries and non-beneficiaries. The findings indicate that the PAMSIMAS Program has been implemented; however, it has not yet been fully optimized. Organizational capacity and information dissemination have been implemented, but limitations remain in implementers’ capacity and in the equitable distribution of information. Support from the village government and the community is relatively good; nevertheless, coordination and the distribution of potential resources still need improvement. This research recommends that future researchers examine the implementation of PAMSIMAS on a broader regional scale and incorporate a more in-depth analysis of sustainability and community participation.

The microbiological quality of clean water in Dusun Kepuhan has not met regulatory standards, posing potential health risks to the community. Laboratory examination identified Escherichia coli at 21 CFU/100 mL and total coliform bacteria at 180 CFU/100 mL, exceeding the permissible limits established by the Indonesian Ministry of Health Regulation No. 2 of 2023. This community service program was conducted to enhance residents’ knowledge and practical skills in managing clean water through the application of a chlorine diffuser as a simple and practical disinfection method. The implementation process included problem identification, coordination with the local PAMSIMAS management, educational sessions, and hands-on demonstrations of diffuser preparation and use. Program effectiveness was evaluated using pre-test and post-test assessments involving 30 participants. The findings indicated a statistically significant improvement in participants knowledge following the training. The chlorine diffuser approach was considered appropriate for the community setting due to its ease of use, affordability, and gradual chlorine release mechanism. Continuous monitoring and sustained community commitment are necessary to ensure long-term implementation of safe water disinfection practices.

Clean water quality is an important factor in supporting public health. In Kaliwader Village, Bener District, Purworejo Regency, drilled well water is used as the main source of clean water, however, based on initial testing, discrepancies were still found in several water quality parameters, particularly turbidity. The Community Service Lecture (KPM) activity of the Al-Qur'an Science University (UNSIQ) aims to improve the quality of drilled well water through the implementation of a water filtration system combined with a venturi aerator and providing education to the community about clean water management. The method used is a descriptive method with an observational approach, including water sampling, laboratory testing at the Regional Health Laboratory UPT, and the implementation of a Malang sand-based filtration unit with venturi aeration. The test results showed that the water turbidity level before treatment reached 8 NTU, exceeding the established quality standards. After the implementation of the filtration system and venturi aerator, the physical quality of the water improved, marked by a decrease in turbidity and an increase in water clarity. Chemical and microbiological parameters were generally within safe limits according to the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. This activity demonstrated that the application of simple technology by UNSIQ KPM students can play an effective role in improving the quality of drilled well water and supporting the provision of more adequate clean water for the people of Kaliwader Village.

Indonesia, as a country with a high level of disaster vulnerability, faces an increased risk of communicable diseases during the emergency response phase due to disrupted sanitation, limited access to clean water, overcrowded evacuation shelters, and weakened health services. This study aims to analyze the strategic role of health workers in health education and the prevention of communicable diseases during disaster emergency response. The method used is a literature review of relevant national and international scientific articles. The findings indicate that health workers have a multidimensional role, not only as providers of curative services but also as educators, change agents, advocates, and collaborators in promotive and preventive efforts. Effective health education, participatory risk communication, strengthened epidemiological surveillance, and the implementation of Infection Prevention and Control (IPC) are key strategies to reduce the risk of communicable disease outbreaks. However, implementation in the field still faces challenges, including limited resources, cross-sectoral coordination constraints, heavy workloads, and suboptimal disaster-related policy systems and standard operating procedures (SOPs). Therefore, strengthening the capacity of health workers through training, policy support, and community-based approaches is necessary to enhance health system resilience in responding to disaster crises.

Water is an essential need for all living things on Earth to support various vital biological processes. Without water, life cannot exist because of its role as a solvent, nutrient transport medium, and temperature regulator. Water in nature does come from various sources such as rivers, lakes, rain, and groundwater, which are not all clear because they are contaminated with particles or other substances, in contrast to mountain springs which are often purer. In this study, a water filtration system was created aimed at making turbid water purify to be suitable for use by assessing the NTU (Nephelometric Turbidity Unit) of turbid water due to suspended particles such as mud or sediment, thus producing clear water suitable for use for household or irrigation purposes. The use of two Siemens S7-1200 PLCs as controllers in the water filtration system is a reliable redundant approach to automate mechanisms such as pump, valve, and NTU sensor settings. PLC 1 is used for the filtration system and PLC 2 is used for the water distribution system. The water distribution process uses a DC pump that runs when it receives input from the water level sensor in the raw water tank and clean water tank. The water filtration process has three main stages: reading the water turbidity level using a turbidity sensor, regulating the water flow rate using a solenoid valve, and filtering the water using filter media. The system's operation can be monitored and controlled through a SCADA system. Both PLCs are connected using an OPC server for communication between the PLC and SCADA. The OPC server sends data from the PLC to the Wonderware InTouch application as the SCADA system. To monitor and control the SCADA system, users must log in to access the system.

In demographic studies, population growth refers to changes in the number of inhabitants over a given period, measured by calculating numerical differences in population size and expressing them within specific time units to illustrate patterns of increase or decline. Based on data from Tembalang District in Figures 2025, the population growth rate in Kedungmundu Village rose by 0.51% between 2016 and 2025, with most residents relying on clean water services provided by PDAM Tirta Moedal as their primary source of drinking water. This study aims to estimate clean water demand based on projected population growth and to design a pipeline network system capable of meeting future needs. The analysis of water demand applies population projection methods, including arithmetic, geometric, and least square approaches, to compare their levels of accuracy, while the clean water distribution network is modeled using EPANET 2.0. One of the main challenges faced by PDAM is that service coverage has not yet been fully optimized. The ten-year projection results indicate that the arithmetic method provides a correlation value closest to 1, estimating a future population of 14,904 people with a total clean water requirement of 3.48 liters per second. To support this projected demand, the proposed network design utilizes High Density Polyethylene (HDPE) pipes with diameters of 12, 10, and 8 inches to ensure efficient and sustainable water distribution.

Clean and Healthy Living Behavior (PHBS) is a promotive and preventive effort aimed at improving the level of public health. The Baduy indigenous community in Leuwi Damar, Kanekes Village, Lebak Regency, Banten Province has local wisdom and traditional lifestyles that influence daily health practices. However, limited access to information and health services is a challenge in implementing PHBS optimally. This article aims to describe the implementation of PHBS education in the Baduy Leuwi Damar community and its impact on community knowledge and attitudes. The method used is a descriptive approach with educational activities through counseling, discussion and simple demonstrations adapted to local culture. Educational material includes personal hygiene, clean water management, environmental sanitation, and healthy living behavior in daily life. The results of the activity showed an increase in public understanding regarding the importance of personal and environmental hygiene, as well as the emergence of a positive attitude towards implementing PHBS without eliminating the traditional values adhered to. PHBS education carried out using a simple cultural and communication approach is considered effective in increasing the health awareness of the Baduy community. Therefore, health education programs based on local wisdom need to continue to be developed as a strategy to improve the health of indigenous communities. .(Riset Kesehatan Dasar,2019).

Peat characteristics include low fertility, high acidity, and poor drainage because it comes from the weathering of organic matter under anaerobic conditions. However, peat has environmental benefits such as absorbing carbon, water buffers, and providing habitat for various unique flora and fauna. The use of peat as agricultural land is widely used by farmers in Pontianak City because it has a very large peatland area with a traditional agricultural system. However, traditional farming will have local knowledge (local wisdom) as a way to minimize damage to the peat ecosystem as an adaptation effort. This study aims to examine the adaptation of peatland management in traditional farming in Pontianak City. The method used in this study is qualitative descriptive and multiple linear regression analysis. The number of research samples was 68 farmers. The results of the study showed that traditional farmers have paid attention to the sustainability of their farming to minimize environmental damage. The results of the study showed that the adaptations carried out were making wells to maintain water availability, using short-lived vegetables that require shallow drainage of 20-30 cm and are adaptive to peat, providing intensive shade, planting trees on empty land, cleaning intensive irrigation, providing ameliorant ash, lime, chicken manure intensively, and arranging planting patterns with diversification. The determining factors for peatland management adaptation include age, land area, length of farming, participation of fire-conscious communities, and intensity of participation in outreach.

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.

This study aims to apply the Principal Component Analysis (PCA) method to identify the main factors influencing poverty in North Sumatra Province. Poverty rates in this region show significant variations among districts and cities, influenced by differences in social, economic, educational, and basic facility availability. The data used in this study include eleven indicators related to population, education, health, access to basic services, and economic conditions. All variables were initially normalized to ensure they had comparable scales, then PCA feasibility tests were conducted using MSA, KMO, and Bartlett's test, which indicated that the data were eligible for further analysis. The results of the PCA revealed three main components explaining a total of 69.91 percent of the variation. The first component represents regional population and economic factors, with the largest contributions coming from population density, open unemployment rate, and per capita expenditure. The second component reflects household living conditions, such as access to clean water, adequate sanitation, and health complaints. The third component describes the educational dimension through indicators of the population aged at the primary and secondary school levels. These findings indicate that poverty in North Sumatra is influenced not only by economic factors but also by the quality of basic services and education levels among the population. Therefore, this research is useful for policymakers at the central and regional government levels to consider the factors influencing the increase in poverty in North Sumatra.

This study aims to describe the condition of clean water access and its impact on public health in Swadaya Village. The research employed a qualitative approach through in-depth interviews with household heads, community leaders, health workers, and local water managers. The findings reveal that access to clean water in Swadaya Village remains very limited. Most residents rely on dug wells and river water for daily needs, while only a small portion use water from the local water utility (PDAM) due to high installation costs and limited pipeline coverage. The water quality often decreases during the dry season, becoming cloudy, odorous, and causing skin irritation. These conditions contribute to the increasing incidence of waterborne diseases such as skin infections, diarrhea, and typhoid fever. Besides infrastructure limitations, the lack of community awareness regarding hygiene and sanitation practices worsens the situation. Although the village government has proposed clean water development programs, their implementation has been hampered by budget constraints. The study concludes that clean water problems in Swadaya Village are not only related to resource availability but also to environmental management and community behavior. Therefore, improving water infrastructure must be accompanied by community education to promote a healthy, safe, and sustainable living environment.

Stunting remains one of the major chronic nutritional problems in Indonesia, including in Oesapa Village, Kelapa Lima District, Kupang City, East Nusa Tenggara Province. This condition is not only caused by inadequate nutritional intake but is also closely related to chronic infections resulting from poor hygiene and sanitation, particularly intestinal parasitic diseases. To reduce the risk of parasitic infections and improve children’s nutritional status, preventive efforts through education and health promotion are essential.This community service activity aimed to increase public awareness and knowledge, especially among parents and caregivers of stunted children, regarding the importance of maintaining hygiene and sanitation to prevent intestinal parasitic diseases. The methods used included participatory approaches such as interactive lectures, group discussions, and practical demonstrations of clean and healthy living behavior (PHBS), food hygiene, clean water management, and household waste disposal. Evaluation was conducted using pre-test and post-test instruments to measure changes in participants’ knowledge.The activities, carried out from May to September 2025 in Oesapa Village, showed a significant improvement in community understanding of hygiene and sanitation practices. Participants demonstrated greater commitment to maintaining environmental cleanliness and adopting healthier daily behaviors. Continuous educational efforts and multisectoral support are needed to help reduce the prevalence of stunting in the region

This study aims to evaluate the effectiveness of the green water system in the nursery phase of Nile tilapia Oreochromis niloticus by observing growth performance, water quality, and survival rate. The experiment was conducted for 21 days using 450-liter circular tanks with two treatments: green water and clear water systems. The green water system was established by adding plankton starter to stimulate algal growth, while the clear water system used clean water with routine siphoning. Observations included absolute length, absolute weight, water quality parameters pH, temperature, dissolved oxygen, nitrite, and phosphate, and survival rate. The results indicate that the green water system provided superior nursery performance compared to clear water. Tilapia seeds reared in green water exhibited higher growth in length and weight, more stable water quality, and a greater survival rate 90% than those in the clear water system 80%. These improvements are attributed to the presence of microalgae, which serve as natural feed as well as bioremediation agents that reduce ammonia, nitrite, and phosphate toxicity. Therefore, the green water system proves to be more effective, economical, and environmentally friendly for tilapia nursery culture compared to the clear water system.

Rapid This study examines the effectiveness of environmental legal instruments in addressing water access inequalities in multicultural rural communities. Despite the existence of various legal frameworks, disparities in water access remain prevalent, especially in rural areas where socio economic, cultural, and governance challenges persist. Legal instruments such as the Water Framework Directive (WFD) and the Clean Water Act (CWA) have proven effective in improving water quality and access in urban settings, but their impact in rural communities is often limited. The study explores the role of legal pluralism, where both statutory and customary laws coexist, in enhancing water governance. It also evaluates the importance of integrating cultural sensitivity into legal frameworks to foster community participation and sustainable water management. Through a mixed methods approach combining legal analysis and socio economic assessments, this study provides insights into the barriers to effective water governance and proposes policy recommendations for improving water access. Key findings suggest that inclusive governance models, which respect local customs and empower communities, lead to more sustainable and equitable water management outcomes. The study highlights the need for legal reforms that recognize the diverse cultural, governance, and infrastructural contexts of rural communities, ensuring that water access policies are both culturally adaptive and legally effective. By integrating these approaches, future policies can more effectively tackle water access inequalities in multicultural rural settings.  

Malang Regency is known as a strategic location with considerable potential as a tourism destination in Indonesia. According to data released by the Central Bureau of Statistics, Malang Regency has recorded 267 tourist destinations spread across 33 districts. This study uses data from one water tourism destination, referred to as Tourism Site X, which focuses on the management and development of recreational areas, including swimming pools, bathing facilities, water attractions, artificial lakes, as well as the management of recreational parks and family facilities such as playgrounds, seating areas, and recreational and educational facilities. Tourism Site X is located in Pakis District, Malang Regency. The reuse of treated wastewater as a non-potable water source for irrigating green open spaces represents a crucial strategic approach to conserving water resources, particularly in water tourism areas such as Tourism Site X, which require substantial water supplies. In practice, the wastewater generated in Tourism Site X mainly originates from domestic sources, including activities such as cleaning swimming pool areas and animal enclosures, toilet usage, and food court operations. This study aims to assess whether the quality of treated wastewater from the wastewater treatment process at Tourism Site X complies with the required standards for green open space irrigation, in accordance with the Regulation of the Minister of Environment/Environmental Control Agency of the Republic of Indonesia Number 11 of 2025 concerning Wastewater Quality Standards and Wastewater Treatment Technologies for Domestic Wastewater, as well as to identify parameters that need to be reduced or eliminated.

The normal flora of chickens refers to the microbial communities that naturally inhabit the gastrointestinal tract and body surfaces of chickens, playing a crucial role in health, digestion, and immunity. This community consists of beneficial bacteria such as Lactobacillus, Bifidobacterium, and Bacillus, which assist in feed fermentation, vitamin synthesis, and inhibition of pathogenic growth. Additionally, the normal flora may include potential pathogenic bacteria such as Escherichia coli, Salmonella spp., and Campylobacter, which can cause diseases if microbial balance is disrupted. The diversity and balance of the microbiota are influenced by various abiotic factors, including feed quality, access to clean water, ambient temperature, humidity, and environmental hygiene. Biotic factors, such as microbial interactions, rearing systems, and contact with other animals, also play a significant role in determining microbial composition. Several studies have shown that the use of feed additives, such as probiotics and phytogenics, can enhance populations of beneficial bacteria while suppressing pathogenic bacteria. Extensive rearing systems, which provide chickens with more space and exposure to natural environments, tend to increase microbiota diversity compared to semi-intensive systems with more restricted conditions. Understanding these factors is essential for developing effective health management strategies and optimizing safe and sustainable poultry production.

This study aims to analyze the process of processing fruit peel waste from juice traders into eco-enzymes as an effort to reduce environmental pollution. The research uses qualitative descriptive methods through direct observation, documentation, and literature studies. Fruit peel waste is fermented at a ratio of 1:3:10 (molasses : fruit waste : water) for three months under anaerobic conditions. The fermentation results show good eco-enzyme characteristics, characterized by a pH of 3, a fresh sour aroma, and a brownish color as an indicator of fermentation success. These findings show that the process of processing eco-enzymes from fruit peel waste can be done simply, cheaply, and environmentally friendly. In addition, the use of eco-enzymes has the potential to reduce the volume of organic waste disposed of in landfills and reduce water and soil pollution. The resulting eco-enzyme also has potential applications as natural cleaners, liquid fertilizers, and odor controllers. Thus, the treatment of fruit peel waste not only supports sustainable environmental management practices, but also encourages the implementation of the circular economy as well as community empowerment ecologically and economically.
