Abstract

Mojokerto City, located in East Java, grapples with a steadily rising waste generation trend accentuated by the COVID-19 pandemic. Drawing data from the National Waste Management Information System (SIPSN) and supplemented with an exhaustive literature review, this study scrutinizes the potential of biodigester technology as a solution to this mounting challenge. Mojokerto's waste, consistent in its composition from 2019 to 2022, is dominated by food waste, making it an ideal candidate for biodigester intervention. The study revealed that existing biodigester facilities in Mojokerto vary in their waste reduction efficiencies yet collectively demonstrate the viability of converting food waste to energy. For instance, the TPS 3R Magersari Berseri facility showcased an impressive waste reduction rate of 85.0%, processing 62.05 tons out of 73 tons of waste received annually. Comparative analyses of other facilities like TPS 3R Pulorejo "Cahaya Berseri" and TPS 3R Muria Berseri were also conducted, revealing varying degrees of efficiency. These facilities underscore the potential of biodigester technology in managing the rising tide of waste and contributing to sustainable energy generation. The findings of this study also call for increased awareness about food conservation, improved waste segregation at the source, and the promotion of composting and other organic waste processing methods, thereby optimizing the overall efficiency of waste management in the city. .

Abstract

Sampah perairan di Tempat Penampungan Sementara (TPS) Jakarta memberikan beban polusi yang signifikan akibat aktivitas manusia. Pemulihan energi menyajikan peluang untuk mendapatkan nilai dari puing-puing ini dan mencapai solusi limbah nol. Di antara komponen limbah di TPS Perintis, puing kayu dari puing-puing sungai di Jakarta mendominasi. Penelitian ini bertujuan untuk memproses puing kayu melalui proses termal di TPS Perintis. Penelitian ini menggunakan analisis hitungan beban di TPS Perintis dan melakukan pengujian laboratorium, termasuk analisis kadar air, analisis kadar abu, penentuan nilai kalor, dan thermal gravimetric analysis (TGA). Generasi harian sampah perairan di TPS Perintis rata-rata mencapai 716,4 m3/hari atau 5,2 ton/hari, dengan puing kayu menyumbang 62,8% dari total. Puing kayu menunjukkan potensi pemulihan energi tertinggi di antara komponen limbah, dengan nilai kalor sebesar 16,43 kWh/kg atau 54.123,38 kWh/hari. Hasil uji TGA menunjukkan bahwa puing kayu dapat digunakan sebagai arang, dengan dekomposisi terjadi pada rentang suhu 200–500°C dan hasil sisa sebesar 14%. Temuan ini menyoroti kelayakan pemulihan energi dari puing kayu di TPS Perintis dan potensi untuk mengubahnya menjadi arang. Kesimpulan penelitian ini menekankan pentingnya penggunaan proses termal dalam mengelola puing-puing sungai, menyediakan solusi berkelanjutan untuk pengelolaan limbah dan pelestarian lingkungan. Abstract River debris at the Waste Temporary Shelter (TPS) Perintis Jakarta poses a significant pollution load resulting from human activities. Energy recovery presents an opportunity to derive value from this debris and achieve a zero-waste solution. Among the waste components at TPS Perintis, wood debris from river debris in Jakarta is predominant. This study aimed to process the wood debris through a thermal process at TPS Perintis. The research employed load count analysis at TPS Perintis and conducted laboratory testing, including moisture content analysis, ash content analysis, calorific value determination, and thermal gravimetric analysis (TGA). The daily generation of river debris at TPS Perintis averaged 7.164 m3/day or 5.2 tons/day, with wood debris accounting for 62.8% of the total. Wood debris exhibited the highest potential for energy recovery among the waste components, with a calorific value of 16.43 kWh/kg or 54,123.38 kWh/day. The TGA test results indicated that wood debris could be utilized as charcoal, with decomposition occurring within the temperature range of 200–500°C and a residue yield of 14%. These findings highlight the feasibility of energy recovery from wood debris at TPS Perintis and the potential for its conversion into charcoal. The study's conclusions emphasize the significance of utilizing thermal processes for managing river debris, providing a sustainable solution for waste management and environmental conservation.

Abstract

Magetan has resources mineral potential of non-metallic minerals and rocks. The mineral variety is a mineral which relates to the people livelihood because it necessary for infrastructure development. There is no mining area zoning until now and it can be used to optimize the management and utilization of potential resources. In Magetan, mining area zoning was carried out by giving weights and assessments to the determining parameters which was conducted by patch method and it utilized Geographic Information System. So, the result of mining area zoning could be grouped into three zones. They were a zone could be granted a mining permit, a zone could be granted a conditional mining permit and a zone could not be granted a mining permit. Determining parameters for mining area zoning were land height, disaster vulnerability, groundwater, river borders, lakes and irrigation buildings, springs, forests and protected areas, agricultural land and cultivation areas, settlements, cultural heritage, tourism and district strategic areas, and land slope. The result of potential resources identification was carried out by analyzing Magetan geological map which was obtained potential resources, like andesite, pumice breccia, sandstone, siltstone and basalt. The zoning of Magetan mining area is a zone could bne granted a mining permit and the area was 9,914.507 Ha or about 14% in a percentage of the area, a zone could be granted a conditional mining permit covering an area of 20,748.29 Ha or about 30% and a zone unable to be granted a mining permit covering an area of 39,296.08 Ha or about 56% of the total area of Magetan.

Abstract

This study evaluates the Hauled Container System (HCS) used in PT. Kamibox Maju Sejahtera's waste management operations. The HCS is a transportation method to transport containers filled with waste and recyclables from collection points to processing or disposal facilities, at PT. Kamibox Maju Sejahtera vehicles travel from a centralized hub in Cisauk to specific pickup locations to load containers. Each vehicle typically handles one location per operational cycle and then transports the loaded container to its destination. Our analysis shows that the HCS system currently enables approximately 2.45 trips per day, which translates to two practical daily trips. This system's simplicity and directness provide ease of management and reduce contamination risk, reassuring the audience about its current effectiveness. The study further explores fuel efficiency and costs, revealing that while the Gran Max is the most fuel-efficient, the Colt Diesel is the most cost-effective. Recommendations include optimizing vehicle use and considering more fuel-efficient alternatives to improve sustainability and reduce operational costs. The findings serve as a guide for PT. Kamibox Maju Sejahtera and similar enterprises were aiming for sustainable waste management.

Abstract

This research examined the intricacies of circular waste management behaviors in Bali, Indonesia, using a Structural Equation Modeling (SEM) framework focused on adaptive capacity. Adaptive capacity was defined through five key dimensions: assets, flexibility, organization, learning, and agency. These elements were critical in shaping the intentions and behaviors associated with sustainable waste management practices. The study systematically explored how these interconnected dimensions of adaptive capacity either facilitated or impeded the adoption of practices aligned with the principles of the circular economy. The SEM approach was employed to map and validate the relationships between the dimensions of adaptive capacity and their impact on waste management behaviors. This analytical method provided a robust framework for understanding the complex dynamics at play, highlighting how different facets of adaptive capacity interacted to influence sustainable practices. Key findings underscored the critical role of individual empowerment, the effectiveness of organizational structures, and the impact of educational initiatives in driving sustainable waste management behaviors. These insights suggested that enhancing individual agency, optimizing organizational protocols, and expanding learning opportunities were pivotal in fostering more sustainable waste management practices.
