Abstract

Final Disposal Sites (landfills) serve as the endpoint in the municipal solid waste management system, functioning as the final destination for our daily waste. Currently, Indonesia is experiencing a waste crisis due to the continuously increasing volume of waste generation, which leads to the rapid overfilling of landfill sites. One of the potential solutions for utilizing landfill waste is the production of Refuse-Derived Fuel (RDF), an alternative fuel derived from solid waste. However, waste that has been buried in landfills generally contains high moisture content, rendering it unsuitable for immediate RDF application. The calorific value of RDF depends greatly on its moisture content, with higher moisture levels resulting in lower energy output. Therefore, a pre-treatment process in the form of drying is necessary to reduce moisture content and optimize the fuel quality of RDF. This study applies the Solar Greenhouse Biodrying (SGB) method as a waste drying technology that combines heat from solar radiation with biological heat generated during aerobic degradation. This method was selected due to its suitability to Indonesia’s tropical climate and its potential for large-scale application without requiring high external energy input. The waste material used in this study was obtained from landfill waste excavated at a depth of 3 meters, with an estimated age of approximately 9 years. In this study, a mixture of fresh waste and excavated landfill waste was dried using various composition ratios: 1:0 (control), 1:1, 1:2, 1:3, and 1:4. The results show that the SGB method effectively reduced moisture content by 27–62.2% and increased the calorific value to a range of 7.5–14 MJ/kg. The waste composition ratio significantly influenced moisture reduction, with the most optimal result found at a 1:2 ratio, which provided the best balance between drying efficiency and energy enhancement. These findings indicate that the SGB method is an effective alternative for waste drying prior to further utilization as RDF.

Abstract

Volume sampah elektronik (e-waste) yang terus meningkat di Indonesia telah memperkuat urgensi penerapan kerangka Extended Producer Responsibility (EPR). Namun, keberhasilan kebijakan tersebut bergantung pada kemampuan untuk mengidentifikasi serta memprioritaskan faktor-faktor kunci yang mempengaruhi pelaksanaannya. Penelitian ini bertujuan untuk menganalisis elemen-elemen yang mempengaruhi penerapan EPR terhadap sampah elektronik di Indonesia dengan menggunakan metode Analytic Network Process (ANP), yaitu suatu metode pengambilan keputusan multikriteria yang mampu menganalisis saling keterkaitan di antara faktor-faktor kompleks. Data diperoleh melalui wawancara dan kuesioner terstruktur yang melibatkan para pemangku kepentingan dari unsur pemerintah, produsen, akademisi, serta masyarakat sipil. Hasil penelitian menunjukkan bahwa instrumen administratif merupakan faktor yang paling berpengaruh dalam mendukung penerapan EPR yang efektif (bobot: 0,368), diikuti oleh instrumen ekonomi (bobot: 0,362) dan instrumen informasi (bobot: 0,271). Di dalam masing-masing kategori tersebut, sistem pengumpulan sampah elektronik (bobot: 0,387), subsidi pengembangan produk (0,278), dan kegiatan sosialisasi kepada produsen (bobot: 0,332) muncul sebagai subkriteria utama. Lebih lanjut, penelitian ini menyoroti peran penting Producer Responsibility Organizations /PRO (bobot: 0,343) dalam mengkoordinasikan para pemangku kepentingan serta memastikan kepatuhan terhadap kebijakan. Berdasarkan hasil prioritas tersebut, artikel ini mengusulkan arah kebijakan bagi Indonesia yang mengintegrasikan reformasi regulasi, mekanisme pembiayaan berkelanjutan, dan keterlibatan strategis para pemangku kepentingan. Temuan ini memberikan panduan yang dapat ditindaklanjuti bagi para pembuat kebijakan dalam mengembangkan sistem EPR yang tangguh dan inklusif untuk menghadapi dampak yang ditimbulkan oleh sampah elektronik
