Abstract

This paper explores Pulau Lengkang, an island near Batam City, known for its natural beauty and cultural heritage. It examines the impact of overcrowding on its aspiration to become a prominent tourism heritage destination. The main goal is to analyze the strengths, weaknesses, opportunities, and threats Pulau Lengkang faces in its development into a renowned tourist hub, with a focus on the challenges of overcrowding and the potential for sustainable tourism. The study employs a qualitative approach, relying on thorough literature review to understand the island's unique cultural and historical aspects and the implications of increasing visitor numbers on its heritage and environment. The findings reveal that while Pulau Lengkang boasts significant cultural and historical appeal, overcrowding threatens to strain its infrastructure and dilute its heritage. However, opportunities for sustainable tourism and cultural preservation present viable pathways to enhance its tourism appeal and support local community well-being. The study suggests that adopting eco-tourism and cultural engagement strategies can help safeguard Pulau Lengkang's heritage and promote sustainable development.

Abstract

This study explores the potential for managing biodegradable marine debris waste in Jakarta City through composting, aiming to reduce and treat this waste effectively. In Jakarta, river debris predominantly consists of materials that degrade easily and are biodegradable. Composting represents the most straightforward method for processing this type of organic waste. The study's objective was to evaluate the feasibility of composting organic biodegradable river debris as a waste management strategy. Data collection was conducted at Emplacement Pluit, utilizing random sampling with the four quadrants method. Out of the total river debris generated daily, which amounts to 309 m³, approximately 9.07 m³/day was found suitable for composting. The composting process resulted in a significant reduction of river debris volume by 50.15% within a 30-day detention period. This process was facilitated by mesophilic microbial activity at temperatures between 30-38°C. During the first two weeks, the composting environment remained acidic until the pH stabilized to a normal range between 6.8 and 7.49. A notable observation was the high initial water content of the river debris, recorded at 53.846%, which only reduced to 42.857% by the end of the 30-day decomposition period. Therefore, a pretreatment step is recommended to optimize the water content before composting. Despite these challenges, the compost produced met the required standards set by SNI 19-7030-2004. This study underscores the importance of managing biodegradable organic waste at its source to alleviate the burden on landfills, which are currently operating beyond their capacity.

Abstract

Energy affordability and financial inclusion remain critical challenges for small island communities, where reliance on imported fossil fuels and high energy costs disproportionately impact low-income households. At the same time, high-income households and the growing tourism sector on these islands hold significant financial capacity to drive equitable energy transitions. This perspective explores the role of high-income stakeholders and tourism operators in promoting energy affordability through retribution mechanisms, adaptive service assets, and flexible organizational models. By leveraging financial resources and investing in clean energy solutions, high-income households and tourism businesses can contribute to a sustainable energy future that benefits all members of the community, bridging the gap between economic growth, energy equity, and environmental sustainability.
