Urban waste management has become a complex challenge due to population growth, urbanization, and economic activities contributing to higher waste generation. Effective waste management systems are required to reduce waste disposed at final disposal sites. This study aims to evaluate the effectiveness of waste management at the TPS 3R Pedalangan Bersinar facility in Semarang City by examining waste separation from the source. The research applied a quantitative approach using mass balance analysis to assess the balance between incoming waste, processed waste, and residual waste in the system. Primary data were collected through field observations, interviews, and operational monitoring for six consecutive days, while secondary data were obtained from the Semarang Environmental Agency. Results show community-based waste banks in Pedalangan demonstrate a high level of effectiveness with a recovery factor reaching 100%, indicating optimal recycling performance and strong community participation. Meanwhile, the TPS 3R facility processes an average waste volume of 16.61 m³/day with reduction of 10.32 m³/day and residual waste of 6.29 m³/day, resulting in a recovery factor of approximately 0.62 categorized as moderate effectiveness. Therefore, strengthening household waste separation, improving operational management, and increasing community participation are recommended to enhance waste reduction and support sustainable urban waste management systems.

This study aims to analyze The Responsibility of the Regional General Hospital (RSUD) TC. Hilers Maumere regarding the practice of burning medical waste and to examine its conformity with the provisions of Law Number 17 of 2023 concerning Health and other regulations related to hazardous waste management. Medical waste management is an important issue because improper handling may cause environmental pollution and pose serious risks to public health. This research employs an empirical legal research method with a descriptive approach, examining how the law operates in society through field data collection and analysis of relevant legal regulations.The results show that RSUD TC. Hilers Maumere implements a waste management system that includes the separation of household waste, liquid waste, and hazardous and toxic waste (B3). Medical waste is categorized and packaged according to its type, weighed, temporarily stored in medical waste storage facilities, and then destroyed using an incinerator or transported by authorized third parties. However, the practice of burning medical waste must be strictly supervised to prevent environmental impacts and potential legal violations. Therefore, stronger supervision, compliance with medical waste management standards, and the implementation of firm legal responsibility are necessary to protect public health and environmental sustainability.

Thousands of metric tonnes of garbage remain unmanaged, and despite available solutions, many people are still reluctant to participate in proper waste disposal. This study aimed to identify the reasons behind the unwillingness of different age groups in Kuta Selatan, Badung, Bali to separate their garbage into biodegradable and non-biodegradable categories. This qualitative research used surveys and interviews for data collection. The survey involved three age groups: adolescents (10–19) with 15 respondents, young adults (20–39) with 15 respondents, and middle adults (40–60) with 11 respondents. Interviews were conducted with two environmental experts, and the data were analyzed using thematic analysis. The results showed that reluctance across age groups stemmed mainly from limited awareness of the environmental benefits of waste separation and the negative impacts of improper disposal. Adolescents additionally cited the lack of strict policies and penalties. Young and middle adults shared similar reasons, mostly linked to insufficient knowledge and low motivation. Environmental experts emphasized the importance of improving public awareness of waste management practices and enhancing waste management infrastructure through additional facilities and better-quality services. Overall, this study highlights the need for stronger policies, improved infrastructure, and increased public education to boost community participation in waste separation in Kuta Selatan.

This study formulates a design concept for the Beach Tourism Resort Area in Botubarani Village by applying tropical architecture that responds to coastal climatic conditions while enhancing the quality of visitor experiences. The research integrates principles of thermal comfort, environmental sustainability, and the ecological potential of coastal environments as the basis for creating climate-adaptive and environmentally responsive tourism areas. The methodology includes site analysis, field observation, climatological assessment, and a literature review related to tropical architecture and coastal tourism design. The collected data were used to determine building orientation, mass layout patterns, visitor capacity, materials, vegetation, and utility systems appropriate for humid tropical climates. The findings show that the site’s position between the sea and the mountains, combined with full-day sun exposure, requires design strategies that maximize cross-ventilation, utilize sloped roofs, provide natural shading, and apply local materials such as wood, bamboo, and red brick. The large spatial needs based on visitor capacity projections are accommodated through a flexible cluster layout that supports visual and functional connectivity between buildings while incorporating green open spaces to enhance microclimate comfort. The utility system is designed using sustainability principles through greywater–blackwater separation, infiltration wells, and recycling-based waste management. This study confirms that the application of tropical architecture in coastal tourism areas can improve thermal comfort, energy efficiency, and environmental sustainability. These findings guide developing tropical tourism area designs that are more adaptive to climate change and more responsive to visitor needs.

Semarang City has experienced significant growth over the past five years (2020 – 2025). Rapid urban development has been positively correlated with increasing environmental burdens, particularly in solid waste generation. In Indonesia, the largest portion of municipal waste consists of food waste, followed by plastic waste. Among these, plastic waste is the most difficult to manage. It is estimated that around 70% of Indonesian households still burn their waste as a means of disposal. The burning of waste, especially plastics, releases toxic emissions such as dioxins, furans, and fine particulates, which pose serious health risks, particularly to the respiratory system. This practice not only worsens air quality but also threatens public health. This community service program focused on providing education about the thermal properties of waste and the negative impacts of plastic burning on both the environment and human health. The program aimed to improve public knowledge of the thermal characteristics of various types of waste and the hazards of plastic burning through accessible scientific outreach. The initiative is expected to raise awareness and understanding of environmentally friendly waste management alternatives such as waste separation, composting, and recycling. The activity was conducted in RW 01, Tugurejo Village, Tugu District, Semarang City.

Bandung Regency, which is experiencing overcapacity in landfills, has implemented a waste management solution involving the separation of organic and inorganic waste. Inorganic waste, which is notoriously difficult to decompose, has prompted the Bandung Regency government to adopt a community-focused approach to waste management, establishing waste banks in school-age communities. However, the project has encountered challenges, as evidenced by the fact that some schools have implemented waste banks but have not been actively engaged in their operations. This has led to the project's suboptimal implementation in Bandung Regency schools.The objective of this study is to identify the challenges associated with the inactivity of waste banks in Bandung Regency schools, as perceived by students and administrators.The study utilises the triple drivers of ecopreneurship, focusing on the economic, social, and environmental benefits of school waste banks. This research employs a mixed methods approach, utilising both quantitative and qualitative data collection methods. The quantitative approach involves the administration of surveys to students, followed by data processing using descriptive statistics. The qualitative method involves conducting interviews with administrators, and the data is processed using the Miles and Huberman model. The findings of the research indicate that the implementation of a waste bank for the management of inorganic waste in a school environment is positively received by the school, despite the presence of obstacles related to waste collection sites, socialisation among students, and differences between administrators and students regarding the most significant focus or choice for implementing waste banks in schools.It is anticipated that the research results will contribute to the understanding of inorganic waste management in waste banks that are less active in the school environment. The study thus recommends further research in schools that are routine or active in waste bank implementation activities, with a view to describing overall information about the implementation of school waste banks, especially in schools in Bandung Regency with school waste bank projects.

This study aims to analyze and evaluate the waste management system in Dusun 3, Pasirwangi Village, Pasirwangi Subdistrict, Garut Regency, which currently lacks both a landfill (TPA) and a temporary disposal site (TPS). As a result, residents are accustomed to improperly disposing of waste, including in the river, leading to environmental pollution. Through socialization efforts, a program for separating organic and non-organic waste was introduced. Organic waste is processed into liquid fertilizer using a mixture of organic waste, rice water, and sugar, which also produces magots that can be cultivated. Non-organic waste is repurposed into handicrafts. Additionally, trash bins were provided to improve disposal facilities. The results of the study show behavioral changes among residents in waste management, although not yet fully optimal. The evaluation highlights the need for more trash bins, increased environmental awareness, as well as the development of handicrafts from non-organic waste and magot cultivation as an economic resource. In conclusion, waste management in Dusun 3 has shown progress but still requires continuous improvement, especially regarding facilities and environmental education.

Background: Household waste management is an important effort in preserving the environment. Household waste, which includes various types of materials such as organic and inorganic waste, has the potential to pollute the environment if not managed properly. The purpose of this writing is to provide a better understanding of the importance of managing household waste in environmental conservation efforts.Method: The research method used is a literature review which involves collecting and analyzing various sources of information relevant to the topic of household waste management. Results: Household waste management is very important to maintain environmental cleanliness and public health. Household waste, which includes organic, inorganic and hazardous waste such as batteries, can pollute the environment if not managed properly. Management methods such as waste separation, recycling and composting can help reduce the negative impact. Despite facing challenges such as minimal public awareness and limited resources, collaboration between the government, community and the private sector can improve household waste management. With good management, apart from protecting the environment and health, it can also provide economic benefits, such as additional income from recycling. Therefore, awareness of the importance of good and sustainable waste management needs to be increased.

Unclean environmental conditions and unhealthy behavior are the causes of the problem of the emergence of infectious diseases. One example of poor clean, healthy living behavior is the lack of awareness in disposing of waste in its place and improper ways of managing household waste. Almost all areas are experiencing difficulties obtaining land as a final disposal site. The government cannot solve the problem of household waste alone. Sentong Village does not correctly manage waste; for example, all waste is burned, and there is no separation between organic and inorganic waste. The purpose of this community service is to increase public awareness by increasing general knowledge about proper waste management and empowering the community to manage waste with the Reduce, Reuse, and Recycle method as one of the appropriate methods in processing household waste. The results of community service activities show that the community is quite enthusiastic when given information about proper waste management; the methods used in these activities are the lecture and discussion methods, then pre-test and post-test are carried out; the community who attended the training were 15 people, and residents agreed to apply the right way of processing waste, starting with the correct way of disposing of waste, namely distinguishing between organic and inorganic waste, so as not to litter in front of the house.
