Problems related to waste have become a hot issue in the community and have received serious attention from policymakers. One practical way to overcome this problem is to manufacture eco-enzyme products whose raw materials use organic waste. Eco enzyme is a fermented process from organic kitchen waste such as fruit and vegetable pulp, sugar, and water until it becomes the final product in liquid fertilizer. This service aims to describe community social activities to overcome waste problems using the eco enzyme concept. The activities carried out were providing counseling related to how to manage household organic waste into eco-enzyme products, introducing and training the use of composter technology to process household organic waste into eco-enzyme products, and motivating and encouraging people to manage household waste into products of economic value. This study uses several methods such as presentation, discussion, question and answer, training, and evaluation handled by lecturers of the Faculty of Agriculture, Timor University. The study results show that people can apply eco enzyme technology, know how to use it, and produce economic value from organic waste.

The waste problem is a problem that has never been resolved until now, especially in the Jakarta area. Every year this problem is unstoppable, giving rise to new problems from health problems, environmental problems, social problems and other problems. Of course, this problem needs the right solution so that waste management and processing according to the mandate of Law 18 of 2008 can run well. One solution offered by the Jakarta regional government is to relocate the waste processing site in Bantargebang to a new place which will later be built into a waste island. This type of research uses normative legal research, which is research carried out by examining the laws and regulations that apply or are applied to a particular legal problem. Normative research is often referred to as doctrinal research, namely research whose object of study is legal and regulatory documents and library materials. In normative research, law is seen as synonymous with written norms, which are created and promulgated by authorized institutions or officials and reviews law as a normative system that is autonomous, independent, closed and detached from real community life. From the solutions offered by the Jakarta regional government that can create "two blades", the first thing that can be seen is that the formation of a waste island is a solution step for handling waste that is currently occurring and also raises the question of how to move existing waste to the waste island. Therefore, appropriate regulations are needed if this plan is later realized. This research method is normative legal research, which is research carried out by examining the laws and regulations that apply or are applied to a particular legal problem.

Waste sludge is sludge that contains a lot of solids resulting from solid-liquid separation from industrial waste. The waste sludge produced from the waste processing process will create new problems in handling because it can pollute the environment. This research will discuss the use of IPAL sludge originating from the Sludge Drying Bed (SDB) to be used as organic fertilizer. In the process of making organic fertilizer in the cake and snack industry by monitoring parameters such as color, texture, smell and properties of organic fertilizer during the process of making organic fertilizer. The characteristic results obtained in this research are blackish brown color, rough texture, earthy odor and the resulting moisture is dry. Thus, the use of WWTP sludge as organic fertilizer offers an innovative and industrial solution that contributes positively to the environment.  

Crude oil contamination is one of the major environmental problems, it generated processing water pollution by hydrocarbon. Microorganisms have been used to remove or reduce the effects of environmental pollutants as bioremediation agents and the fact it is environmentally friendly. This study isolated two Klebsiella strains, Klebsiella pneumonia and Klebsiella oxytoca from wastewater of the North refineries company in Baiji according to the morphological and biochemical characteristics.This work aimed to evaluated the capacity of two Klebsiella strains to degrade the petroleum hydrocarbons efficacy, which excreted from wastewater of the North refineries company. The results showed that the Klebsiella oxytoca exhibited a higher hydrocarbon degradation capacity of 67.75% compared to Klebsiella pneumonia, which recorded 45.81%. While mixed culture (Klebsiella oxytoca and Klebsiella pneumonia) was recorded a biodegradation rate of 63.35%. The results showed that efficacy of Klebsiella oxytoca as biodegradation for oil wastewater was 30% higher than other strain.

Economic growth and increasing population density in adulthood require awareness regarding environmental concern. Caring for the environment is an important thing that must be done to prevent natural damage and maintain ecosystem balance. Nganjuk Regency, with a population density of around 1,103,902 people in 2020, of course produces quite a lot of household waste. There is a need to increase awareness and change attitudes regarding waste sorting and processing to create a clean and healthy environment, which is the aim of holding waste bin procurement activities. Seeing that Setren Village SDGs number 12, namely Environmentally Conscious Village Consumption and Production, still has not met the target score that must be achieved, knowledge regarding waste sorting needs to be emphasized more. The method used was direct observation in the Setren Village environment, then a Focus Group Discussion was held regarding handling waste problems to create a healthy environment. The results of the community service carried out are the provision of waste sorting bins and socialization of waste sorting. Apart from that, there has been an increase in knowledge regarding types of waste for the people of Setren Village.

The implementation of environmental law influenced the success of the Eco Town program in maintaining the sustainability of river ecosystems by providing a strong foundation for preserving the environment. The implementation of strict regulations related to environmental protection and river management is key in ensuring that development within Eco Town does not damage the river ecosystem. In several case studies such as the Ciliwung River and the Brantas River, the implementation of environmental law has recorded significant improvements in the sustainability of river ecosystems. The main challenges faced in implementing environmental laws to support Eco Town programs are resource limitations, especially in terms of funds, technology, and natural resources. These limitations may hinder the effectiveness of the program and affect the ability to address environmental problems such as industrial or domestic waste management, and maintain ecological balance. To overcome these challenges, concrete measures such as improved accessibility and technology transfer, sustainable management of natural resources, and investment in environmental infrastructure are needed. By ensuring a solid environmental law implementation and paying attention to these limitations, the Eco Town program can run more effectively and efficiently in maintaining the sustainability of the river ecosystem and realizing a vision of sustainable development.

Waste is one of the biggest environmental problems in Indonesia. Based on data from the 2014 Central Statistics Agency (in Angga & Djunaidi, 2017) it shows that Indonesia produces around 187.2 million tons of waste / year and is in second place as the largest waste producer in the world. Waste not only comes from households but also from the school environment. If this waste is left unchecked, it can cause disease. This large amount of waste is also caused by people's lack of concern for the environment. Therefore, it requires an appropriate management strategy, one of which is through recycling. The waste recycling training aims to increase knowledge of dealing with plastic waste and develop the creativity of Purwakarta State Primary School teachers so that they are able to process waste into learning media as well as capital for students to understand learning more easily through waste recycling training. Implementation methods include environmental observation, problem identification, determining service activities, coordinating service activities with prospective participants, implementing training. The waste recycling training activity has been successful and running smoothly, able to develop creativity and increase teachers' knowledge regarding waste managent.

Qualitative research methods with primary data types through interviews and observations are used to directly identify the processing process of selling products. The results found show that there are various types of solid and liquid waste that have not been managed properly. Therefore, having good waste management alternatives, such as improving waste management infrastructure, can prevent sustainable environmental damage and improve the quality of life of local communities.

Environmental problems are showing a significant increase day by day. The current environmental problem is one of the most urgent problems that needs to be resolved immediately, both from the government and from the surrounding community. Environmental pollution is formed from human activities which produce waste that enters the environment. Pollution carried out by PT. BOOS. Based on the data we submitted for research using a descriptive qualitative research method, this aims to describe a research phenomenon carried out in Bandar Maruhur, Simalungun Regency in May 2024. The establishment of factories in residential areas creates environmental instability due to toxic waste that has not been fully processed, creating biota. the river around the factory environment is disturbed. Apart from that, it also worsens the strong and unpleasant odor that often spreads around. Waste disposal activities by PT. BOSS, this unpleasant odor is often smelled around the environment. Pollution itself often disrupts community activities.

The problem of household waste/waste is no stranger to Indonesian society. This happens because of the lack of socialization in the community about how important it is to keep the environment clean. The Kogoro Settlement, Tanjungpinang City, is one of the areas experiencing household garbage/waste problems, which until now have not found a clear solution to this problem. Residential areas, which are almost entirely above sea level, exacerbate the situation in the area due to the large amount of garbage and waste carried by sea water. This problem must be resolved as soon as possible to maintain sustainability and the ecosystem runs smoothly. Therefore the government of Tanjungpinang City issued Regional Regulation No. 03 of 2015 concerning waste management, which aims to solve various problems and provide the concept of handling management as well as sanctions for those who violate these rules. In this study, we will examine the policies implemented by the Tanjungpinang City government in dealing with environmental problems. Using the Normative-Empirical method, this research will delve deeper into these environmental problems which include the existence of sanctions, ideas, rules in Tanjungpinang including the Kosgoro settlement. However, in implementing these rules, the Government of Kosgoro did not implement them as they should. This is supported by the people who are only given advice to throw garbage into trash cans which are quite far above the settlement due to the narrow access road in the Kosgoro area. Lack of government attention makes people less aware of managing household waste and waste.  

The Ministry of Trade's decision making regarding the types of goods that are allowed to enter the country is based on consideration of several threats that have the potential to harm the nation. Three types of goods that are not allowed to enter the country based on Minister of Trade Regulation (Permendag) No. 40 of 2022 include used sacks, used bags and used clothes. The types of goods mentioned in the Minister of Trade Regulation (Permendag) are considered to cause many problems in various sectors of life including economic, social and environmental problems. This research uses the literature review method as an approach to explore and analyze phenomena related to the policy of banning used clothing imports. The research was carried out by searching scientific journals, articles, research reports and other related documents that discuss the consumption of used clothes, its impact and the policies taken by the government in responding to this phenomenon. This decision making is a rational action carried out by the government based on logical thinking and considerations. This prohibition was carried out because of the increase in textile waste in the country, obstruction of the market for Indonesian products and loss of state income which, if left unchecked without regulations, could result in disparities in various sectors of life.

In the midst of rapid industrial progress and global economic growth, the use of plastic has increased dramatically, causing serious environmental problems due to the accumulation of plastic waste. One of the most worrying aspects of this problem is the presence of microplastics, namely plastic particles less than five millimeters in size. The more accumulation of plastic waste found in the waters will cause damage to the surrounding water and sea environment, plastic waste that is not collected will be exposed to sunlight and exposure to air, the longer it will decompose into small particles called microplastics. In this research, the author researched using the library research method, namely by collecting and studying existing literature from various sources such as: journals, articles, books and others related to this research. Microplastics have spread widely in the environment, from oceans to land, and have had a serious impact on organisms and ecosystems throughout the world. The process by which microplastics are formed, their distribution in the environment, their impact on aquatic and terrestrial organisms, and their potential impact on human health are the main focus research and public attention. To overcome the microplastic problem, a holistic approach is needed that involves collaboration across sectors and scientific disciplines. Handling and mitigation efforts must cover various aspects, starting from regulating the use of single-use plastics, more effective management of plastic waste, developing technology for detecting and eliminating microplastics, to educating the public about the dangers of microplastics and the importance of environmentally friendly behavior. Concrete steps such as banning the use of single-use plastics, promoting recycling, innovation in product design, and cross-border cooperation in managing plastic waste are key in efforts to reduce the negative impact of microplastics. Only by taking these steps together can we create a cleaner, healthier and more sustainable environment for future generations.

The aim of this research is to understand the extent to which the Sentiong community cares about managing household waste. The method used is descriptive qualitative using data collection techniques carried out through investigations and interviews. The results of the research imply that the awareness of the Sentiong community in dominating household waste is still in the small category. This is due to the large amount of waste being thrown away haphazardly, the lack of waste sorting, and the lack of public knowledge. Throwing away rubbish is a daily activity that everyone does, this can lead to deviant behavior if it is carried out by people who behave badly towards the environment. Waste can cause problems, but it can also strengthen the economic life of the community. Various types of waste produced from industry and households, if not managed well and correctly, will have the potential to weaken the community's economy, this is because it will absorb quite a large amount of funds for handling waste that is not managed well and correctly, which is considered from a hygiene, health and environmental perspective.

Waste management is something that must receive extra attention from the community itself and from actors whose activities produce remnants of production that will be disposed of, with all consideration of the impacts resulting from the waste, both good and bad impacts, a waste management is needed so that waste-producing parties can wisely treat the rest of their productivity activities. Which is where the ultimate goal can create a social life in a healthy, peaceful, safe, and comfortable society so as to minimize and even eliminate social conflicts that occur due to waste problems in society.  

Agriculture is one of the main business sectors used as the livelihood of the people of Sumberpitu village with dairy farming as an accompanying business unit. However, from the existing potential, there are several problems such as steps and expensive inorganic fertilizers. From the results of deepening the problem through interviews, it shows that farmers in Sumberpitu Village do not have any knowledge and skills to use cow urine as liquid organic fertilizer in their farming business. The purpose of this study is to conduct extension program on the use of cow urine waste as biourine with the addition of pineapple skin bioactivators and analyze behavior changes in aspects of knowledge, attitudes and skills of farmers in Sumberpitu village. The research method used in this study is the Level III action research method. The evaluation results show that extension services can increase farmers' knowledge from a percentage of pre-test scores of 50% to 82% in post-test scores, which can be categorized as very high. In the aspect of attitude, the percentage of pre-test scores of 48% increased to 76% in post-test scores and was included in the high category so as to show a positive attitude towards the extension program material delivered. While in the aspect of presentation skills, the post test score is 83%, which can be categorized as “very high”. These results show that the extension program provided has proven effective in changing farmer behavior in increasing knowledge and attitudes as well as developing farmers' skills in utilizing cow urine waste as biourine with the addition of pineapple peel as a bioactivator.

Bookkeeping administration is an important aspect in waste bank activities because it has the benefit of recording and carrying out complete and detailed reporting within a certain time period, so that there are no differences in calculations between customers and the Waste Bank management. The importance of bookkeeping administration in managing the Waste Bank (recording the entry and exit of each type of waste managed by the Waste Bank), can help optimize waste management and increase the effectiveness of waste management. Simple bookkeeping (in the form of Socialization) was introduced in the transaction cycle at the Bank Sampah "Sami Berkah", Kelurahan Meteseh, Kecamatan Tembalang, Semarang (making a Chart of Account, Journal from proof of transactions, posting to the ledger and subsidiary books, up to making Financial Reports). The administrative management of the Bank Sampah Sami Berkah has met the minimum requirements of the Dinas Lingkungan Hidup, starting from books, officers, waste reception schedules, until the waste deposited has been sorted by customers/members. Likewise, the duties and responsibilities of waste bank management officers are in accordance with the job and description of the organizational structure. The proposed use of the information system at the "Sami Berkah" Waste Bank is the use of an Android-based application or web system (mobile web access) in order to accommodate the need for faster and easier information access for customers/Members and Waste Bank managers, as well as being able to overcome the Bank's operational problems. Waste starts from customer registration, savings transaction processes to reporting, efficiently and with integrity. and easy to manage by admins and monitored by users directly.
