This study analyzes the potential use of cockle shell waste and coal fly ash as alternative raw materials in the production of composite brake pads. The high volume of industrial and fisheries waste, which has not been optimally utilized, encourages the exploration of environmentally friendly materials with adequate mechanical performance. The main focus of this research is the compressive strength of the produced brake pads, as this parameter is crucial for ensuring effective and safe braking performance. The method used includes the mixing and molding of composite materials with varying compositions of cockle shell and fly ash, followed by compressive strength testing according to standards. This study also takes into account the environmental impact of using waste as filler material, which is expected to reduce reliance on conventional materials and decrease waste that contaminates the environment. The results of the study are expected to provide empirical data on the potential of these two wastes as fillers in brake pad matrices and to identify the optimal formulation that provides the highest compressive strength. This study contributes to the development of sustainable braking materials and efforts to mitigate the environmental impact of waste, while also opening opportunities for the reuse of waste that has previously been poorly managed.

Natural resource management in Paccellekang Village, which includes rice paddies, plantations, and teak trees, remains suboptimal despite its significant potential, particularly the abundant wood waste. This wood waste largely originates from agricultural activities, plantations, and small-scale wood processing. Currently, this waste is often simply burned or dumped, potentially polluting the environment and causing air pollution. However, if managed properly, wood waste can be transformed into high-value products that can provide financial benefits to the community. This community service activity aims to empower farmer groups through training in processing wood waste into marketable products such as charcoal, liquid smoke, and wood flour. These products not only have economic value but are also useful in various sectors, for example, liquid smoke as a natural preservative, charcoal as an environmentally friendly fuel, and wood flour as an industrial raw material. The program implementation method uses a structured approach that includes initial observations to identify potential partners and needs, outreach to provide a comprehensive understanding of the program's objectives, and training in wood waste processing technology. Furthermore, intensive mentoring and evaluation of implementation results are provided to ensure program sustainability. The results demonstrated that the farmer group members understood the concept of productive wood waste management and demonstrated high enthusiasm for developing innovative products. This program successfully improved the community's skills in utilizing local resources while reducing the negative impact of waste on the environment. Thus, this activity contributed to increasing community income and supporting sustainable economic development in Paccellekang Village.

This study aims to examine the impact of waste on natural ecosystems in the Karawang area, West Java. As one of the largest industrial estates in Indonesia, Karawang faces serious challenges related to industrial and domestic waste management. Poorly managed liquid and solid waste has polluted rivers, farmland, and forest areas, and disrupted the balance of local ecosystems. This study uses a qualitative approach through field observations, interviews with residents and related agencies, and secondary data analysis. The results of the study show that waste pollution has a direct impact on the decline in water quality, habitat damage, and the decline in biodiversity at several points in Karawang. In addition, the surrounding community also feels the impact through health problems and reduced agricultural yields. This study recommends the need to strengthen waste management regulations, increase supervision of industry, and involve the community in environmental conservation efforts. These findings are expected to be considered in the formulation of sustainable environmental policies in Karawang.

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.

Clean living behavior can be done by maintaining the sustainability of life can be done by reducing waste, saving energy, planting trees, and not littering. Waste sorting can be done by separating organic and inorganic waste into different trash bins. In addition, inorganic waste can also be separated again based on its type, such as plastic, paper, glass, and metal. Facilitates the process of collecting and processing waste for recycling. The Principles of Clean and Healthy Living Behavior (PHBS) recommend the use of waste sorting methods. The daily habits that we do to maintain personal and environmental cleanliness consist of this behavior. . Along with the emergence of various diseases that often attack children aged 6-12 years, PHBS in schools is a collection of behaviors carried out by students, teachers, and school residents based on learning so that they are able to independently prevent disease, improve their health. Implementation of better waste sorting practices can reduce the negative impact of waste on the environment, increase the efficiency of waste management, and provide long-term benefits for school residents. Schools are one of the places that have great potential to educate students about good waste management. SD Negeri 2 Kelusa has problems related to the lack of student knowledge about waste sorting and utilization, especially organic waste. Most students at SD Negeri 2 Kelusa still have limited understanding of the types of waste and how to process it. Most students do not realize and understand that organic waste can be reused, so they tend to throw it away with other waste.

Industrial waste management is a crucial aspect of maintaining environmental sustainability and the health of communities around industrial areas. This study aims to empower the community through education on industrial waste management at Jordan Bakery Factory in Kendari, Southeast Sulawesi. The methods used were participatory observation and interviews with the waste management staff at the factory. The results of the community service show that the factory has implemented a good system for managing liquid and solid waste, including a liquid waste filtration process and economic utilization of solid waste. In addition, the service team also prepared educational materials in the form of pamphlets containing information about types of waste, proper management methods, and the environmental impact of waste. This education is expected to increase awareness and participation among the community and factory workers in responsible waste management. This study contributes positively to environmentally friendly and sustainable industrial waste management in the Kendari area

Agricultural waste treatment is an organism that offers innovative solutions to reduce the negative environmental impact of waste while increasing agricultural productivity. By using microorganisms such as bacteria, fungi, and actinomycetes, wastes such as straw, manure, and coffee grounds can be effectively treated. This biological process accelerates the decomposition of organic matter into more benign substances and nutrients, such as nitrogen, phosphorus and potassium, which are essential for plant growth. In addition to improving soil fertility, the use of organic fertilizers also reduces dependence on chemical fertilizers, greenhouse gas emissions, and sustainable agriculture. The aim of this study was to investigate the role of microbiology in agricultural waste transformation by examining its mechanisms, potentials, and challenges. The results of this study show that microorganism-based technologies contribute to more environmentally friendly practices and reinforce fundamental economic principles. Processing agricultural waste into organic fertilizer is a strategic step in realizing sector sustainability.
