Oil palm empty fruit bunches (EFB) are oil palm biomass that can be processed into organic amendments and energy sources. Currently, the methods to utilize these solid waste have become a concern because it is related to the implementation of the zero-waste concept. Therefore, this study aimed to evaluate the current management of EFB waste from palm oil mills based on the concept of zero waste and renewable energy. This study used secondary data analysis of palm oil mills, field interviews, and literature study to evaluate EFB waste management. The results showed that the ratio of EFB and CPO produced by palm oil mills was around 27:23. The average EFB produced by manufacturers is 3,558.8 tons/month. Most palm oil mills manage their EFB wastes using mulching treatment. This showed that palm oil mills in Indonesia have yet to implement the existing technologies that many researchers have developed. Composting and anaerobic digestion are the alternative treatments that can be implemented by palm oil mills since both can reduce the EFB waste and produce products that can be sold and reused. The government of Indonesia can encourage palm oil mills to shift their waste management from using mulching treatment to anaerobic digestion and composting treatment.

Solid waste management is a complex issue, and this was especially true during the COVID-19 pandemic in Indonesia. Several challenges related to this issue emerged because of the pandemic, during which countries with limited resources heavily relied on community participation. This study investigates the factors that contribute to the collective action of urban communities in waste management as a solution to raising awareness. This study adopted a quantitative method that incorporated four independent variables and one dependent variable with a 4-point Likert scale questionnaire. The data were collected through a survey using a purposive sampling method. The data collected are proportional because there is no sampling frame in this study. An analysis of the 200 samples collected in Jakarta reveals that community participation, social norms, social influence, and socioeconomic status impact collective action. However, the result from an ordinal regression analysis only shows community participation and social influence as significant variables with corresponding odds ratios of .263/.379 and .053/.168 for every one-unit increase. This study concludes that higher community participation and social influence will likely affect people’s collective action in waste management. Policies and programs incorporating community participation and social influence can be implemented based on the findings to tackle waste management awareness issues.

Peers advisory is important to help improving individual behavior, including waste-management and handling activities. The data analyzed in this study were derived from primary data collection on some populous provinces in Indonesia, along with waste-management problem. A survey has been conducted on more than 2,000 observations at individual level, gathered from 563 household to examine how social and education affect the probability of a person to follow correct waste-handling actions: put trash righteously. This study found that urban citizens in Indonesia are probably 1.7 times more likely to follow correct waste-handling actions, if they’re have been taught in environmental caring. This study also found that peers’ advice in terms of environmental caring will affect people 3.77 times more likely to put trash righteously. Overall, this study found that peer’s socialization environment is important in reshaping human’s behavior on handling wastes. In addition, good habits formed during childhood, and self-initiative behavior has not also been important enough to solve waste-handling problems.

Introduction: Population growth in urban areas, fuelled by migration from rural areas, has changed lifestyles and socio-cultural dynamics. The dynamic lifestyle of urban communities changes consumption behaviour so that people prefer practical and economical products. There are fundamental issues that arise in the waste management system in Indonesia, including limited waste management capacity in the regions, inadequate infrastructure, implementation of regulations, and lack of public awareness including the consumer goods manufacturing industry on post-consumption waste management issues. This study aims to understand the perception and level of community participation as well as the role of the informal sector in post-consumption plastic waste management, with a focus on the implementation of the extended producer responsibility (EPR) scheme. Methods: Data was collected through a questionnaire survey and literature study in five areas of DKI Jakarta. Through the concept of Extended Producer Responsibility (EPR), the manufacturing industry is encouraged to contribute to the management of plastic packaging waste produced. This research uses quantitative and qualitative methods with data analysis using descriptive statistics. Finding: The results show that the community supports EPR-related regulations and is ready to participate in plastic waste management schemes. This positive perception reflects changes in socio-cultural values that prioritise environmental concerns. The informal sector also makes an important contribution to plastic waste reduction, especially through collection, distribution, and processing activities in stalls and waste banks. Community support and the role of the informal sector in plastic waste management reflect changes in social attitudes and behaviours that are increasingly concerned about the environment. Conclusion: Therefore, active involvement in plastic waste reduction initiatives also reflects a cultural change that is increasingly integrated in urban communities.

Background: SNI People's Market is a national standard in the construction and management of trade facilities. The Healthy Market implementation policy serves to regulate the health of the market environment. The policy of implementing SNI for People's Market and the policy of organizing Healthy Market are expected to be the guidelines in managing people's market. However, in reality, not all public markets in DKI Jakarta implement the two policies. The purpose of the research is to analyze the condition of public markets in Perumda Pasar Jaya in terms of SNI criteria for Public Markets and Healthy Markets, and analyze the implementation of SNI for Public Markets and Healthy Markets and based on the assessment of the central government and local government. Methods: The research method used is a combination of quantitative and qualitative methods using a qualitative approach that combines descriptive statistics and a comparison matrix. Results: The research results based on field observations show that the condition of public markets in Perumda Pasar Jaya has limitations in the provision of facilities that are a requirement in the implementation of SNI for Public Markets and Healthy Markets. In addition, the implementation of SNI People's Market and Healthy Market has obstacles in its implementation from the point of view of the central government and local government.

Marine transportation has the potential to pose a pollution threat through ship accidents. Dangerous dry bulk cargoes carried may provide direct exposure to the marine environment. Dry bulk cargoes such as coal and iron ore are examples of dangerous dry bulk cargoes. However, current information regarding the dangers of pollution from spilled dry bulk cargo is still very limited. Therefore, this study aims to analyze the pollution hazard from spills of dry bulk cargo due to the X ship accident. The method used is a mixed methods descriptive analysis of hazards and socio-economic impacts. The results obtained are that the dry bulk cargo spill has an impact on marine environmental conditions, with an estimated spill distribution of 874,187km2 and there is no socio-economic impact on the community around the location.
