Abstract

Tempat Pengolahan Sampah Terpadu (TPST) Refuse Derived Fuel (RDF) Jeruklegi terletak di Kecamatan Jeruklegi, Kabupaten Cilacap. TPST ini merupakan sebuah fasilitas pengolahan sampah menjadi produk RDF yang memiliki kapasitas pengolahan sampah sebesar 120 ton/hari. Sampah tersebut diolah melalui proses pencacahan dan pengeringan. Penelitian ini bertujuan untuk menentukan kuantitas dan komposisi sampah efektif untuk diolah di TPST RDF, mengkaji pengaruh penambahan bioaktivator EM4, dan mengkaji aspek keuangan yang ada di TPST RDF. Pada penelitian ini, dilakukan kegiatan sampling, observasi lapangan, dan studi literatur. Sampling dilakukan untuk menentukan kuantitas sampah dengan metode weight-volume analysis. Selanjutnya, komposisi sampah didapatkan dengan metode random sampling dan teknik perempatan. Observasi dilakukan untuk mendapatkan data tahapan pengolahan sampah, kuantitas, dan kualitas hasil olahan sampah yang dilihat dari kadar air, ukuran sampah, lama waktu pengeringan, dan intensitas aerasi, serta spesifikasi dan jumlah fasilitas pengolahan sampah. Selain itu, dibutuhkan data penunjang untuk penelitian ini, yaitu jumlah Sumber Daya Manusia (SDM) yang terlibat dalam kegiatan pengolahan sampah serta biaya produksi pengolahan sampah. Data penunjang didapatkan dari arsip kantor TPST RDF Jeruklegi. Data tersebut digunakan untuk mengkaji aspek teknis dan aspek keuangan di TPST RDF Jeruklegi. Studi literatur dilakukan untuk mendapatkan acuan mengenai komposisi efektif sampah yang dapat dijadikan RDF dan pengaruh penambahan bioaktivator EM4 terhadap proses pengeringan. Berdasarkan hasil sampling berat, volume, dan komposisi sampah yang masuk ke TPST RDF, maka didapatkan berat rata-rata sampah per harinya adalah sebesar 138,85 ton/hari dengan volume sebesar 466,55 m³/hari. Komposisi sampah yang didapatkan, yaitu jenis biodegradable (59,93%), plastik (16,39%), kertas (4,32%), dan lainnya (19,35%). Adapun hasil penentuan komposisi efektif sampah untuk dijadikan bahan baku pada produksi RDF terdiri dari biodegradable (51%), plastik (14%), kertas (15%), dan lainnya (20%) dengan estimasi nilai kalor produk RDF yang dihasilkan sebesar 4281,86 kkal/kg. Bioaktivator EM4 direncanakan untuk ditambahkan pada proses biodrying di TPST RDF dengan estimasi dapat mempercepat proses biodrying dari 21 hari menjadi 15 hari. Penambahan bioaktivator tersebut mampu menurunkan kadar air dari 65,88% menjadi 22,72% dalam waktu 15 hari. Sehingga, hal tersebut dapat meningkatkan produktivitas TPST RDF dalam menghasilkan produk RDF sebesar 40%. Pengadaan bioaktivator EM4 juga menimbulkan anggaran dana baru yang dapat menyebabkan penurunan pendapatan TPST RDF sebanyak 3,8%/tahun.

The Jeruklegi Refuse Derived Fuel (RDF) Integrated Waste Treatment Plant (TPST) is located in Jeruklegi District, Cilacap Regency. TPST is a waste processing facility into RDF products that has a waste processing capacity of 120 tons/day. The waste is processed through the process of enumeration and drying. This study aims to determine the quantity and composition of effective waste to be processed at TPST RDF, examine the effect of adding EM4 bioactivators, and examine the financial aspects of TPST RDF. In this study, sampling activities, field observations, and literature studies were carried out. Sampling is carried out to determine the quantity of waste using the weight-volume analysis method. Furthermore, the composition of the waste is obtained by the random sampling method and the intersection technique. Observations were made to obtain data on the stages of waste processing, quantity, and quality of processed waste in terms of water content, waste size, length of drying time, and aeration intensity, as well as specifications and number of waste processing facilities. In addition, supporting data was needed for this study, namely the number of Human Resources (HR) involved in waste processing activities and the production costs of waste processing. Supporting data was obtained from the archives of the TPST RDF Jeruklegi office. The data is used to examine the technical and financial aspects of TPST RDF Jeruklegi. A literature study was conducted to obtain a reference on the effective composition of waste that can be used as RDF and the effect of adding EM4 bioactivators on the drying process. Based on the results of sampling the weight, volume, and composition of waste entering the RDF TPST, it was found that the average weight of waste per day was 138.85 tons/day with a volume of 466.55 m³/day. The composition of the waste obtained was biodegradable (59.93%), plastic (16.39%), paper (4.32%), and others (19.35%). The results of determining the effective composition of waste to be used as raw materials in RDF production consist of biodegradable (51%), plastic (14%), paper (15%), and others (20%) with an estimated calorific value of RDF products produced of 4281.86 kcal/kg. EM4 bioactivators are planned to be added to the biodrying process at TPST RDF with an estimate that it can accelerate the biodrying process from 21 days to 15 days. The addition of bioactivators was able to reduce the water content from 65.88% to 22.72% within 15 days. Thus, it can increase the productivity of RDF TPST in producing RDF products by 40%. The procurement of EM4 bioactivators also creates a new budget which can lead to a decrease in RDF TPST revenue by 3.8%/year.
