Abstract
Timbulan sampah di Kabupaten Tulungagung dari tahun ke tahun terus meningkat selaras dengan bertambahnya jumlah penduduk. Sampah yang dihasilkan diangkut ke TPS dan kemudian ditimbun di TPA. Pada saat ini di Kabupaten Tulungagung hanya memiliki satu TPA, terletak di Desa Segawe, Kecamatan Pagerwojo. TPA Segawe mempunyai luas ±6 ha dan telah beroperasi selama 30 tahun. Kondisi terkini TPA Segawe sudah melebihi kapasitas yang tersedia. Oleh karena itu, tujuan dari penelitian ini adalah untuk menganalisis potensi galian timbunan sampah di TPA Segawe sebagai bahan baku Refuse Derived Fuel (RDF) dan Material Urug. Pengambilan sampel dilakukan dengan menggali timbunan sampah di zona pasif di TPA Segawe secara manual dengan ukuran 0,6 × 0,6 × 1 m (p × l × t) pada 6 titik. Kemudian sampel dianalisis komposisi, kadar air, volatile matter, kadar abu dan nilai kalor. Metode analisis komposisi mengacu pada SNI 19-3964-1994 tentang Metode Pengambilan dan Pengukuran Contoh Timbulan dan Komposisi Sampah Perkotaan. Pengujian kadar air dilakukan dengan metode ASTM D2216 – 10 dan volatile matter dengan metode ASTM D3175 – 07. Sedangkan, metode penentuan nilai kalor dilakukan dengan alat bomb calorimeter parr C3000 di Laboratorium Limbah Padat dan B3 Departemen Teknik Lingkungan ITS. Hasil dari penelitian ini menunjukkan bahwa komposisi material gali didominasi oleh sampah plastik dengan persentase 56,3%. Komposisi terbesar kedua adalah material gali berukuran 10-30 mm dengan persentase 10,8% dan komposisi terbesar ketiga adalah material gali berukuran <10 mm dengan persentase 9,8%. Kemudian, hasil analisis karakteristik galian timbunan sampah di TPA Segawe menunjukkan bahwa sampel tanah penutup, material gali berukuran< 10 dan 10-30 mm mempunyai rata-rata kadar air 30,79-53,79%. Hal tersebut tidak sesuai dengan kriteria standar material urug yang digunakan yaitu 10-28%. Sedangkan dari ukuran partikel material gali <10 dan 10-30 mm memenuhi kriteria standar. Material gali tersebut dapat dimanfaatkan menjadi material urug setelah dilakukan proses pengeringan. Sedangkan untuk analisis potensi material gali sebagai RDF, khususnya sampel >30 mm mempunyai rata-rata nilai kalor 10,35-15,62 MJ/kg, kadar volatile matter 70,67-70,92%, kadar abu 29,08-29,33%, dan kadar air 32,62-46,62%. Nilai kalor dan volatile matter memenuhi kriteria standar RDF, sedangkan kadar air dan kadar abu melebihi kriteria standar yang digunakan. Untuk itu perlu dilakukan pre-treatment untuk menyesuaikan kadar air dan kadar abu dengan standar material urug dan RDF yang berlaku.

Municipal solid waste (MSW) generation in Tulungagung Regency from year-to-year increase in line with the increase in population. The generated MSW will be transported to the temporary shelter and then to the landfill. Current condition of Segawe MSW landfill in Tulungagung Regency, has exceeded its capacity. Purpose of this study is to seek the possibility of reusing the landfill for MSW disposal site due to limited land availability. Therefore, this study aimed to determine the potential use of dumped MSW at Segawe landfill as raw material for Refuse Derived Fuel (RDF) and Backfill Material. Samples were collected by manual excavation at passive zone of the landfill in six predetermined locations with a size 0,6 × 0,6 × 1 m (l × w × d). The samples were sieved using 10 mm and 30 mm mesh sieves. Composition analysis was applied to 100 kg weight of each sample, referred to Indonesian National Standards (SNI) 19-3964-1994 concerning Collection and Determination Methods for MSW Generation and Composition Analyses. Moisture content and volatile matter analyses were performed using ASTM D2216-10 and D3175-07 methods, respectively. Calorific value was measured using bomb calorimeter parr C3000. Results of the study showed that the composition of the excavated MSW is dominated by plastic waste with a percentage of 56.3%. The second largest composition is excavated waste measuring 10-30 mm with a percentage of 10.8% and the third largest composition is excavated waste measuring <10 mm with a percentage of 9.8%. Then, the results of the analysis of the characteristics of mined material Segawe landfill showed that overburden samples, excavated waste measuring < 10 and 10-30 mm had an average moisture content in the range of 30.79- 53.79%. This is not by the standard criteria for backfill material used, namely 10-28%. Meanwhile, the particle size of the excavated waste <10 and 10-30 mm met the standard criteria. The excavated waste can be used as backfill material after the drying process is carried out. As for the analysis of the potential of excavated material as RDF, especially samples >30 mm have an average heating value in the range of 10.35-15.62 MJ/kg, volatile matter content 70.67- 70.92%, the ash content 29.08-29.33%, and the moisture content 32.62-46.62%. The calorific value and volatile matter meet the RDF criteria, while the ash content and moisture content exceed the standard criteria used. For this reason, pretreatment effort is required to make the mined MSW materials meet the quality standard for backfill materials and RDF
