Extreme poverty remains a major challenge in rural areas of Indonesia, including Nagori Bandar Manik, Pamatang Sidamanik District, Simalungun Regency. The 2025 UINSU Community Service Program (KKN) was carried out to empower local communities through various activities covering economic, educational, religious, social-environmental, and health aspects. This program employed a qualitative approach by involving active community participation in needs assessment, socialization, training, and evaluation. In the economic aspect, workshops on dishwashing liquid and herbal pesticide production were implemented as alternative household businesses. The educational sector included religious moderation through a short movie screening Mabbere, anti-bullying campaigns, ecoprint totebag training, and teaching at kindergarten, elementary, and junior high school levels. In the religious field, activities included Qur’an learning after Maghrib with children and Yasin recitals for both men and women. The social-environmental aspect was realized through community clean-up, educational boards on waste decomposition, distribution of garbage bins, and environmental awareness campaigns. Meanwhile, the health aspect focused on education about clean and healthy living behaviors, stunting prevention campaigns, and community exercise. The findings revealed improvements in entrepreneurial skills, children’s literacy, spiritual values, environmental awareness, and healthy lifestyles. The implication highlights that multidimensional community empowerment can serve as an effective strategy to reduce extreme poverty and promote sustainable village development.  

The problem of waste in rural areas is still a serious issue that has an impact on environmental health and the quality of life of the community. Batu Licin Village, Gunung Lengkuas Village, East Bintan District, Bintan Regency is one of the areas that faces similar problems, where household waste is still scattered and has not been handled optimally. This community service activity offers innovative solutions through the manufacture of rocket stoves as a means of efficiently burning certain organic and inorganic waste, as well as the construction of garbage booths as a place to store and sort waste before further processing. The implementation method involves counseling to residents, making prototypes, and direct practice of using rocket stoves and garbage booths by local communities. In addition, this activity also emphasizes the importance of changing community behavior in managing waste with the 3R (reduce, reuse, recycle) principle. The results of the activity show an increase in public awareness in managing waste independently, reducing the accumulation of waste in the village environment, and the emergence of alternative waste processing that is environmentally friendly, energy-efficient, and easy to apply. This innovation not only helps overcome the problem of household waste, but also provides educational value and empowers the community in maintaining the cleanliness and sustainability of the village environment. With the implementation of rocket stoves and garbage booths, it is hoped that a cleaner, healthier, and more viable village environment will be created in the long term.

Clean water is a basic human need to achieve a healthy standard of living. Human survival is greatly influenced by the quality of water and the availability of water in sufficient quantities. In Keramasan Village, there are still many people who have bad habits in providing clean water. People use the river as a place to bathe, wash clothes, wash dishes and throw away garbage.The level of knowledge, attitudes and actions of the community regarding the provision of clean water in Keramasan Village, Kertapati District, Palembang City.This type of research is descriptive research with a cross-sectional design. The population in this study were 159 families living in RT 11 and RT 12 in Keramasan Village. The total sample of respondents in this study was 67 families. Sampling was carried out using a random sampling technique, which aims to ensure that the sample can represent all families.From the results of the study on the provision of clean water, the level of knowledge of 46.3% of respondents had a low level of knowledge, in contrast to the attitude of 67.1% of respondents showing a good attitude. and 59.7% of respondents have poor actions regarding the provision of clean water.From the results obtained, it can be concluded that the community in Keramasan sub-district regarding the provision of clean water, at the level of knowledge, most respondents still have a low level of knowledge, most respondents already have attitudes in the good category, and most people have actions in the bad category.

Coastal environmental pollution is an increasingly complex problem in Indonesia, especially due to uncontrolled waste disposal. This study aims to analyze the impact of waste disposal on the environment in the coastal area of Putra Deli Beach, Deli Serdang Regency. The research approach used is mixed-method with data collection through direct observation, semi-structured interviews, and literature study. The results showed that plastic waste dominates the types of waste found at the research site and is the main cause of marine ecosystem pollution. The impacts include damage to marine biota habitat, decreased tourist attraction, public health problems, and economic losses for local businesses. The lack of waste management facilities and low environmental awareness also exacerbate this condition. Therefore, an integrated waste management strategy based on community and stakeholder collaboration is needed to maintain the sustainability of the coastal environment.

Garbage become problem complex in life urban areas , especially in Medan as Mother city North Sumatra Province . Research This analyze impact management Trash in Place Disposal End (TPA) Terjun , Medan Marelan District , regarding environment surrounding area .

Findings This reinforced by BPS data (2018) which shows density Medan 's population reached 8,342 people /km², correlated with high volume of waste . Research This recommend implementation system management rubbish integrated based on principle health environment and economy circular For reduce impact negative .

The increasing waste problem requires innovative solutions that are efficient and sustainable. This study aims to design and build an Internet of Things (IoT) based garbage cleaning robot that can be monitored and controlled remotely. This system is designed by utilizing a microcontroller as the main brain, sensors to detect the presence of garbage, and an IoT-based communication module that allows monitoring and control of the robot via mobile devices or the web. Based on the results of the analysis and testing carried out, this study shows that the use of ESP8266 in the RC Trans Robot motor control with the Blynk application has succeeded in significantly increasing system efficiency. The system successfully responds to user input via a mobile application and can control the movement of the robot in real-time. The performance of the robot system controlled via a WiFi network shows good stability in various test scenarios. The robot can operate effectively within a distance that matches the range of the WiFi network, with fast control response and reliable communication.

Abstract: This study aims to analyze the PAI integration learning model with identity elements (clean and healthy living) in group B students. The research used a qualitative approach with a case study research type. The research location was in ABA 7 Karangjati Kindergarten, Blora Regency, with 33 student informants and two teachers. Data collection techniques through observation, interviews, and documentation. The data validity test used a credibility test where this study used triangulation. Data analysis techniques used data condensation, data presentation, and drawing conclusions. The results of the study showed that the application of PAI integration learning with identity elements (clean and healthy living) increased students' awareness of environmental cleanliness, both at school and at home. In addition, changing 90% of student behavior in terms of cleanliness, students have thrown garbage in its place, picked up scattered garbage, rearranged what has been used when playing, studying, and so on. They have a sense of responsibility for themselves and the surrounding space. In this activity, 20% of teachers or parents continue to remind their children to maintain cleanliness in order to live a clean and healthy life.
