Environmental pollution is a common problem in cities and can increase the likelihood of flooding. The purpose of this study is to analyze environmental pollution as a cause of flooding in the Pekapuran Street area, Depok City. This study applies a descriptive method with a qualitative approach. Data were obtained through observation, documentation, and literature review. Based on the results of the study, it was found that the accumulation of household waste around the drainage channels causes obstruction of water flow, which triggers flooding during rain. In addition, the shallow, mud-filled, and poorly maintained drainage conditions increase the risk of flooding. Low levels of public awareness of environmental cleanliness are also factors that exacerbate the condition. This study concludes that flooding on Pekapuran Street is influenced not only by high rainfall, but also by environmental pollution and a suboptimal drainage system. Based on this, better waste management and drainage maintenance are needed to minimize the risk of flooding in the area.

The quality of life and well-being of women in Indonesia can be measured through the Female Life Expectancy indicator. Data on Female Life Expectancy from 2022 to 2024 shows a nationally positive trend; however, a significant disparity persists across provinces, particularly between the Western and Eastern regions of Indonesia. The nation still faces challenges in ensuring an equitable quality of life for women, as evidenced by the national Female Life Expectancy (FLE) in 2024 at 74.21 years, which remains lower than ASEAN counterparts such as Singapore at 83.86 years. Furthermore, regional imbalances are reflected in the performance gap between D.I. Yogyakarta (77.4 years) and West Sulawesi (68.28 years). This study aims to analyze the effects of Women's Income Contribution, Access to Clean Water, the Number of Families Receiving Social Assistance, and Women's Mean Years of Schooling on Female Life Expectancy in Indonesia during the 2022–2024 period. The estimation method applied in this research is the Fixed Effect Model (FEM) via a quantitative panel data regression approach, spanning an observation area of 33 provinces (n=99). Based on the analysis, Female Life Expectancy is proven to be positively and significantly influenced by Women's Mean Years of Schooling and Access to Clean Water. These findings indicate that human resource quality and environmental conditions serve as dominant factors in driving up Female Life Expectancy. Therefore, government policy interventions should ideally focus on expanding educational access for women and ensuring the equitable distribution of clean water infrastructure.

The flash floods that struck Aceh Tamiang caused infrastructure damage and contaminated clean water sources, making it difficult for residents to obtain potable water. This situation increases the risk of water-borne diseases and worsens the post-disaster situation. This research aims to develop a large-scale, simple water filtration prototype as an emergency response solution that is effective, economical, and easy to implement by affected communities. The methods used include field observation, water sampling, testing simple physical parameters (turbidity, color, odor, and pH), and designing a gravity-based, multi-stage filtration system without electricity. The prototype uses a combination of filter media such as gravel, silica sand, activated charcoal, and natural fibers in a drum system. Test results show a decrease in turbidity levels from 150–300 NTU to 5–15 NTU after the filtration process, as well as an increase in pH to near neutral. The filtered water is declared suitable for sanitation and consumption after undergoing a further disinfection process. In addition to implementing the technology, this research also includes public education regarding the selection of safe water sources and maintenance of the filtration system. Based on these results, this large-scale simple water filtration prototype is effective as an appropriate technological solution in handling the post-disaster clean water crisis and has the potential to be replicated in other flood-prone areas.

The problem of stunting is still a serious issue in health development in Indonesia because it has an impact on the quality of human resources. This study aims to analyze the efforts of the Pagomogo Village Government in handling stunting. The research uses a descriptive qualitative approach with data collection techniques through observation, interviews, and documentation. Informants were determined using purposive sampling consisting of village governments, health workers, cadres, and the community. The results of the study show that the village government has implemented various programs, such as Supplementary Feeding (PMT), strengthening Human Development Cadres (KPM), improving services through community institutions, and sanitation development. However, the implementation of the program has not been optimal because it is still constrained by economic factors, low public awareness, limited counseling, and access to clean water. This study concludes that the main problem does not lie in the availability of programs, but in the implementation and sustainability aspects. Therefore, it is necessary to strengthen community empowerment, improve education, and evaluate results-based programs.

Waste management has become an increasingly complex environmental issue, particularly in urban areas and densely populated settlements. The lack of public awareness in disposing of waste properly has caused numerous negative impacts, including soil and water pollution, flooding due to clogged drainage systems, reduced environmental aesthetics, and the spread of infectious diseases. These conditions indicate that the waste problem is not merely a technical issue of collection and disposal, but also strongly related to people’s behavior and environmental awareness. Therefore, a simple, practical, and effective approach is required to encourage behavioral change in daily life. One alternative solution is through visual education by using waste signboards that display educational and persuasive messages. These signboards are installed in strategic locations to serve as direct reminders for residents to care more about environmental cleanliness. This study aims to analyze the effectiveness of waste education signboards in improving community understanding and discipline in waste disposal practices. The methods applied included counseling sessions, participatory discussions with residents, designing communicative and attractive signboards, and installing them in high-traffic areas such as main roads, schools, worship places, and public spaces. The results of the activity indicated an increase in public knowledge regarding the impacts of waste, active participation in maintaining cleanliness, and a significant reduction in littering behavior around the areas where the signboards were installed. Furthermore, residents gave positive feedback and expressed their willingness to expand the initiative by adding more signboards in other locations as part of sustainable action. In conclusion, educational signboards proved to be an effective, low-cost, and practical medium to raise community awareness. Beyond delivering environmental messages, the signboards also helped strengthen collective commitment among residents to create a clean, healthy, and sustainable living environment.

Furthermore, this activity opens up new economic opportunities for the community by creating creative products from waste. Evaluation results show that the community-based waste management model is effective in fostering community independence in waste processing, creating a cleaner environment, and encouraging a culture of sustainable living at the village level. The success of this program is expected to serve as an example for replication in other areas with similar challenges. Continued support from the village government and cross-sector collaboration are key to this initiative's continued growth and long-term impact.

This community service activity was carried out in Dahu Village, Pandeglang Regency, with the main objective of introducing and implementing biopore infiltration hole technology as a simple and environmentally friendly solution to address waterlogging and organic waste management. Biopores are small-diameter vertical holes dug into the ground and then filled with organic waste, such as dry leaves, vegetable scraps, or food scraps. This organic waste will naturally decompose through a decomposition process, producing compost that is useful for fertilizing the soil. Furthermore, the presence of biopore holes can improve the groundwater absorption capacity, thereby reducing the risk of waterlogging and minor flooding around residential areas. During the implementation, we as students not only provided theoretical explanations through socialization sessions but also actively participated directly in the field. Together with residents, we practiced making biopore holes, starting from the stages of preparing tools and materials, the process of drilling the soil, and filling the holes with organic waste. This practical activity was designed to help the community understand the steps for making biopores independently and utilizing them sustainably. The results of the activity showed an increase in community understanding and awareness of the importance of easy, affordable, and beneficial waste management. The community is beginning to realize that waste processing does not always require large costs or complicated technology. Biopore holes have been proven effective in accelerating rainwater absorption, reducing household waste volume, and improving soil fertility. Beyond the environmental impact, this activity also strengthens relationships between students and villagers through the collaboration established during the biopore construction process. Thus, this program is expected to be the first step towards a cleaner, healthier, and more sustainable village.

Limited sanitation facilities among street vendors, particularly those selling meatballs, chicken noodles, and porridge, often pose a problem that impacts food safety. One common practice is repeatedly washing bowls and spoons with just a bucket of water, followed by drying the utensils with a cloth. This contaminated water can transmit pathogenic microorganisms that cause foodborne illnesses, increasing the risk of health problems for consumers. This problem requires a practical solution that street vendors can implement, taking into account limited space, mobility, and operational costs. This community service activity used a pre-experimental design method with a simple technological engineering approach to improve the sanitation of tableware. The innovation developed was a portable bowl washer made from used mineral water gallons, modified to be mobile, efficient, and water-efficient. The manufacturing process included design, assembly, testing, and evaluation with street vendors. Success was measured by observing the level of cleanliness of the tableware before and after use, as well as assessing the level of satisfaction and ease of use by the vendors. The results showed that the implementation of this portable sanitation device increased the effectiveness of tableware washing, reduced the repeated use of dirty water, and minimized the risk of cross-contamination. Partnering vendors stated that the device is practical, lightweight, and doesn't disrupt their sales activities. They hope this innovation will be replicated by other vendors and that local governments will consider implementing it as a standard for mobile food sanitation. This effort will not only improve the hygiene of eating utensils but also contribute to preventing foodborne illnesses in the community.
