The problem of plastic waste has developed into an urgent global environmental crisis, due to the nature of plastic that is difficult to decompose and can persist in the environment for hundreds of years. This study explores pyrolysis as a promising oxygen-free thermal conversion technology to overcome plastic waste by converting it into valuable products such as oil, gas, and char. The main focus of the study is the use of zeolite catalysts in the pyrolysis of polyethylene plastic waste from household waste, with a total mass of 1.5 kg of plastic waste and 200 grams of zeolite catalyst. The catalyst used, natural zeolite from Klaten, Central Java, was heated at a temperature of ±200°C before being used in a pyrolysis reactor at an operating temperature of 450°C for ±4 hours. The results showed that the use of zeolite catalysts reduced the percentage of liquid and solid products, but increased the percentage of gas products. In addition, the use of catalysts tended to reduce the content of medium fractions (C11-C22) and paraffin fractions, while increasing the light fractions (C4-C11) and olefin fractions. These findings indicate the potential of pyrolysis as a sustainable solution to the plastic waste problem with positive impacts on the environment and economy.

Green architecture is one way to create a house or building that is environmentally friendly.

This paper explores the role of Green Sukuk in advancing sustainable development in Indonesia, with a focus on its alignment with Islamic law and the principles of maqashid al-shariah. The research aims to examine the impact of Green Sukuk as a financial instrument in supporting environmentally friendly projects such as renewable energy, waste management, and green transportation. Using a qualitative approach, the study analyzes the legal, economic, and ethical dimensions of Green Sukuk, as well as its contributions to social justice and environmental sustainability. The findings reveal that Green Sukuk not only fulfills Islamic financial principles by being free from haram elements like riba, gharar, and maisir, but also serves as an instrument for equitable development by directing funds to sustainable projects that benefit society and the environment. However, the study identifies challenges such as limited private sector involvement, lack of in-depth project evaluation, and insufficient public awareness. The research suggests that future studies should focus on evaluating the effectiveness of Green Sukuk projects on the ground, conduct international comparisons to identify best practices, and enhance the role of the private sector and public engagement in expanding the scope of Green Sukuk. Ultimately, this paper contributes to the growing discourse on Islamic finance and sustainability, demonstrating that Green Sukuk is not only a financial tool but also a medium for social and environmental responsibility in line with Islamic teachings.

This study aims to describe and analyze the strategies implemented by the Environmental Agency (DLH) of Karimun Regency in managing waste and to evaluate the effectiveness of these implementations in the field. Employing a qualitative descriptive approach, data were collected through in-depth interviews, observations, and document reviews. Findings reveal that DLH Karimun has developed and executed key strategies, including the formulation of the Regional Waste Management Master Plan (RIPSD), optimization of Temporary Waste Disposal Sites (TPS) with 3R principles, active collaboration with waste banks and community groups, and community-based education and socialization efforts. However, operational challenges persist, particularly in waste transportation fleet distribution, handling of the Sememal Final Disposal Site (TPA), and monitoring and evaluation mechanisms that remain suboptimal. Additional challenges include limited human resources and funding, low public awareness, and regulatory conflicts impacting strategic decision-making. Nevertheless, the strategies implemented have contributed to improvements in environmental cleanliness across several sub-districts and increased volumes of processed waste through recycling initiatives. Community involvement through schools, youth organizations, family welfare groups, mutual cooperation activities, and waste banks proved critical to success. The study recommends the adoption of digital-based waste management systems (smart waste management), capacity building for DLH personnel, community empowerment, and revision of local regulations to support sustainable waste management. This will enhance the effectiveness and sustainability of DLH Karimun’s waste management strategies moving forward.

This study aims to find out the collaboration of actors in waste management in landfills (TPA). This study uses descriptive research using qualitative research methods and using Ratner's (2012) theory which includes Identification of Barriers and Opportunities, Debate Strategies to Influence, and Collaborative Action Planning. There were 5 informants in this study. The results of the study show that the collaboration that occurs in waste management has gone well, but there are still obstacles in overcoming existing problems. To identify obstacles and opportunities, there are situations and needs as well as resources that must be met, the collaboration that occurs between the Environment and Hygiene Agency and the head of waste management and b3 waste has been running but is not optimal enough due to the lack of resources in facilitating infrastructure facilities at landfills. Debate strategies to influence and increase public awareness and understanding require socialization related to understanding how to manage waste properly. The Head of the Environment and Hygiene Agency together with the Head of the B3 Waste Management Division have collaborated with the Mutiara Timor Waste Bank in providing effective socialization to reduce the volume of existing waste, but many people do not understand the socialization. Planning this cooperation action, there is a collaborative implementation strategy where the actors collaborate in planning the right implementation strategy to reduce the volume of waste in the landfill, but the collaboration between the Head of the Environment and Hygiene Agency and the Mutiara Timor Waste Bank has targeted 20% in handling the volume of waste, but the cooperation is only 5% that can reduce the volume of waste in the landfill because the socialization provided is still not understood by the Public. For the purpose and purpose of this cooperation is the target in reducing and handling waste from 2018-2025, if this cooperation runs effectively and successfully, slowly the volume of waste in landfills will decrease by itself.

This activity was carried out in Kampung Enam with the aim of sharing knowledge and skills with the community and students about how to turn seashell waste into handmade crafts that can be sold. We used a face-to-face approach through socialization and training, one of which was making wall decorations in the shape of flowers. Besides involving the local people, students also took part in this activity so they could develop economic independence. The results showed that seashell waste has promising potential, both economically and socially, especially if developed into small environmentally friendly businesses. Hopefully, activities like this can continue and become an example of how to develop local crafts and increase the income of the people around Kampung Enam, Tarakan.

Environmental crises such as climate change, ecosystem degradation, and pollution have prompted countries to formulate environmental policies aimed at preserving environmental sustainability. However, the effectiveness of these policies is often questioned, particularly in their implementation. This article aims to evaluate the impacts of environmental policies implemented over the past decade on biodiversity, air quality, and waste management, as well as to identify implementation barriers and provide recommendations for policy improvement. The study employs a literature review method by analyzing various scientific sources, policy reports, and related documents. The evaluation results indicate that economic incentive-based policies, such as carbon taxes and renewable energy subsidies, tend to be more effective in reducing emissions and promoting clean energy adoption. Nevertheless, policy implementation frequently faces obstacles including lack of political support, limited resources, public resistance, and weak inter-sectoral coordination. Improvement strategies are needed, including enhanced cross-sector collaboration, strengthened data and information systems, and public education to support the success of sustainable environmental policies.
