Abstract

The phenomenon of environmental damage is a very serious global issue and an increasingly complex problem. This damage is due to the exploitation of excess economic value without considering future sustainability (over exploitation). This happened after humans practiced the capitalist economy while ignoring Islamic values. Various efforts to overcome this environmental damage have been carried out, including various policies and regulations that regulate human activities in interacting with their environment as measured by the achievements of SDG's (Sustainable Development Goal's). Experts have also tried various applications of concepts and theories as well as models of approaches and technologies that are possible to overcome the problem. These efforts so far have not significantly paid off, in fact, tending to increase the level of environmental damage. The idea of returning to the application of religious values and spirituality is one of the alternatives that needs to be applied through a holistic approach. The purpose of writing this article is to develop a model of the role of Islamic society in environmental management and sustainable development. Exploratory methods are used to map the role of Islamic communities in environmental restoration and rehabilitation movements, eco-islamic boarding school, and non-governmental organizations that are active in the community and also through Islamic dawah content. The results showed that there is a significant role that can be used as a role model, so that it can be replicated by other Islamic societies around the world.

Abstract

The Ciliwung River, one of the large rivers in Indonesia, has experienced damage in the upstream area from waste pollution, landfills, and environmental damage. The Ciliwung watershed has experienced shallowing and is often affected by foam. There are many stakeholders who are concerned and have carried out many caring actions, including the Ciliwung Care Community (KPC) in Kedung Halang District, Bogor City. Therefore, this situation must be resolved properly, immediately, and sustainably. Stakeholders who have potential for the development and sustainability of the Ciliwung River are formulated through focus group discussions and divided based on stakeholder quadrants. Activities that can be carried out as a follow-up to stakeholder mapping and engagement are workshops inviting all stakeholders to present the existing conditions of each segment of the Ciliwung River so that sustainability activities can be formulated that can be implemented through support between stakeholders.

Abstract

The socioeconomic feasibility of Waste-to-Energy (WtE) facilities is analyzed through a case study in South Jakarta, emphasizing its potential as a sustainable urban waste management solution. This study evaluates the comparative costs and benefits of implementing an Intermediate Waste Treatment Facility (ITF) in three prospective locations: Sukapura (North Jakarta), Pesanggrahan, and Petukangan Selatan (South Jakarta). Results highlight Sukapura’s strategic advantage due to its industrial zoning, resulting in lower residential density, reduced social resistance, and minimized environmental costs. By contrast, higher costs are associated with South Jakarta sites due to greater population densities, leading to amplified pollution impacts. Key findings reveal that WtE facilities generate significant environmental and economic benefits, including reduced greenhouse gas emissions, improved air and water quality, job creation, and regional budget efficiencies. The integration of circular economy principles, such as waste reduction and resource efficiency, further underscores the importance of sustainable waste management strategies. However, successful WtE implementation requires careful alignment with land-use planning and community engagement to address socio-environmental challenges effectively. This study offers valuable insights for policymakers and urban planners, proposing that strategic site selection and adaptive approaches are critical for achieving long-term sustainability in waste management.

Abstract

Sustainable development is a key focus of Indonesia’s policy framework, as mandated by Law No. 32 of 2009 and Government Regulation No. 46 of 2016, which emphasize integrating Environmental Carrying Capacity and Load Capacity (CCLC) into development planning. This study identifies challenges in current CCLC assessments, including limited data accuracy and inconsistent methodologies. To address these issues, an innovative Environmental CCLC Determination System is proposed, integrating ecosystem services and advanced spatial modeling. The research methodology combines a comprehensive literature review and expert interviews to analyze existing practices and design the system. The proposed system incorporates decision support tools and spatial data analysis to provide a scientifically grounded, unbiased, and accessible framework for policymakers. Initial implementation will involve collaboration with academic experts, universities, and local governments, particularly in Bogor Regency and Bogor City. The system is expected to significantly enhance regional planning and environmental stewardship by the end of the 2025–2030 development period, aligning policies with sustainable development goals.

Abstract

This study examines the barriers to green job development in Indonesia, focusing on economic, educational, and societal dimensions. Using a literature review methodology, the research synthesizes findings from academic studies, policy reports, and government publications to identify key challenges. Economic barriers include insufficient investment, inadequate fiscal incentives, and limited financial access for small and medium enterprises (SMEs). Educational barriers highlight a lack of targeted training programs, insufficient integration of sustainability in curricula, and disparities in access to education in rural areas. Societal barriers are reflected in low public awareness, negative perceptions of green jobs, and limited inclusion of marginalized communities. These challenges constrain the growth of green industries and limit workforce readiness for emerging sectors. The study concludes that addressing these barriers requires coordinated efforts, such as enhancing investments, reforming education systems, and fostering societal engagement.

Abstract

This study evaluates the transportation infrastructure in Bogor Regency by employing a comprehensive Connectivity Index to assess the extent of integration across various transportation modes. The research aims to address pressing challenges, including limited accessibility, inadequate integration, and traffic congestion. Using data on road and rail networks and transportation nodes, three key indicators were analyzed: road-based public transport connectivity, rail-based transport coverage, and the integration of major transportation nodes. Results reveal that road-based connectivity stands at 33.55%, while rail-based connectivity ratio and integrated node percentage are at 0.052 km/km² and 17.02%, respectively. These findings highlight the suboptimal state of intermodal integration in Bogor Regency. The study concludes that targeted investments in rail network expansion and the development of multimodal transportation nodes are imperative. Enhanced integration and connectivity will support sustainable transportation systems, improve mobility, and foster economic development in the region.
