Abstract
Kabupaten Sidoarjo – Jawa Timur memiliki jumlah penduduk 2.144.588 jiwa pada tahun 2024 dan terus bertambah setiap tahunnya. Jumlah penduduk Kabupaten Sidoarjo yang tergolong cukup besar menghasilkan timbulan sampah ± 1086 ton/hari dan terus meningkat seiring peningkatan jumlah penduduk termasuk proses urbanisasi. Pengelolaan sampah di Kabupaten Sidoarjo dilakukan dengan cara pemilahan di sumber dilanjutkan ke tempat penampungan sampah sementara (TPS) dan berakhir di Tempat Pemrosesan Akhir (TPA) Griyo Mulyo yang menggunakan teknologi Refused Derived Fuel (RDF) untuk mengolah sampah menjadi energi. Penelitian ini bertujuan untuk menentukan efektifitas pengelolaan sampah dengan teknologi RDF di TPA Griyo Mulyo.
Metode yang digunakan dalam penelitian ini adalah menghitung timbulan sampah yang masuk ke TPA, komposisi bahan baku, serta melakukan analisis terhadap nilai Kalor, Kadar Abu dan Kadar air komposisi sampah sebagai bahan baku RDF dan RDF sebagai produk, baik pada musim hujan maupun musim kemarau. Serta membandingkan hasil pengujian pada sampel dengan metode Statistical Product and Service Solutions (SPSS).
Pengamatan terhadap kondisi eksisting menunjukan bahwa timbulan sampah yang masuk ke TPA Griyo Mulyo sebesar 554 ton/hari atau 336,35 kg/m3 dengan komposisi : sisa makanan dan kebun 62,25%, LDPE 9,50%, PET 7,85%, logam 1,52% dan residu 6,82%. Hasil analisis terhadap sampah sebagai bahan baku dengan komposisi Bio Degradable dan Degradable pada musim kemarau menunjukan nilai sampel 1 (25% Bio Degradable dan 75% Degradable) sebesar : nilai kalor 3544,98 Kkal/kg, kadar Abu 17,34% dan kadar air 27,94% , sampel 2 (50% Bio Degradable dan 50% an Bio Degradable) sebesar : nilai kalor 3863,52 Kkal/kg, kadar abu 15,21% dan kadar air 24,41% dan sampel 3 (75% Bio Degradable dan 25% Degradable) sebesar : nilai kalor 4124,22 Kkal/kg, kadar abu 20,46% dan kadar air 28,44%, sedangkan pada musim penghujan menunjukan nilai sampel 1 (25% Bio Degradable dan 75% Degradable) sebesar : nilai kalor 2488,12 Kkal/kg, kadar abu 16,05% dan kadar air 33,24%, sampel 2 (50% Bio Degradable dan 50% an Bio Degradable) sebesar : nilai kalor 2821,06 Kkal/kg, kadar abu 18,41% dan kadar air 34,63% sedangkan sampel 3 (75% Bio Degradable dan 25% Degradable) sebesar : nilai kalor 3041,53 Kkal/kg, kadar abu 13,62% dan kadar air 37,33%. Untuk hasil pengujian produk RDF tipe briket pada musim kemarau memiliki nilai kalor 4684,89 Kkal/Kg, kadar abu 14,23% dan kadar abu 8,21 %, sudah sesuai dengan standar SNI 8966:2021. Sedangkan untuk produk RDF tipe briket pada musim penghujan tidak memenuhi standar SNI 8966:2021 yaitu dengan nilai kalor 4216,39 Kkal/kg, kadar abu 18,69% dan kadar air 22,02%. Hasil dari analisis SPSS menunjukan bahwa variabel jenis sampah, komposisi dan musim memiliki pengaruh yang signifikan terhadap parameter Nilai Kalor, Kadar Abur dan Kadar Air.

Sidoarjo Regency, East Java, will have a population of 2,144,588 people in 2024, which will continue to increase every year. The population of Sidoarjo Regency, which is quite large, produces waste generation of ± 1086 tons/day and continues to increase along with the increase in population, including the urbanization process. Waste management in Sidoarjo Regency is carried out by sorting it at the source, continuing to the temporary waste storage site (TPS), and ending at the Griyo Mulyo Final Processing Site (TPA), which uses refused derived fuel (RDF) technology to process waste into energy. This research aims to determine the effectiveness of waste management using RDF technology at the Griyo Mulyo TPA.
The method used in this research is calculating the generation of waste entering the landfill and the composition of raw materials, as well as analyzing the calorific value, ash content, and water content of waste composition as raw material for RDF and RDF as a product, both in the rainy season and the dry season. As well as comparing test results on samples using the Statistical Product and Service Solutions (SPSS) method.
Observations of existing conditions show that the generation of waste entering the Griyo Mulyo TPA is 554 tons/day, or 336.35 kg/m3, with the following compositions: food and garden waste (62.25%), LDPE (9.50%), PET (7.85%), metal (1.5%), and residue (6.82%). The results of the analysis of waste as raw material with the composition Bio Degradable and Degradable in the dry season show the value of sample 1 (25% Bio Degradable and 75% Degradable) of: calorific value 3544.98 Kcal/kg, Ash content 17.34% and water content 27.94%, sample 2 (50% Bio Degradable and 50% Bio Degradable) is: calorific value 3863.52 Kcal/kg, ash content 15.21% and water content 24.41% and sample 3 (75% Bio Degradable and 25% Degradable) amounting to: calorific value of 4124.22 Kcal/kg, ash content of 20.46% and water content of 28.44%, while in the rainy season it shows a sample value of 1 (25% Bio Degradable and 75% Degradable) of : calorific value 2488.12 Kcal/kg, ash content 16.05% and water content 33.24%, sample 2 (50% Bio Degradable and 50% Bio Degradable) is : calorific value 2821.06 Kcal/kg, content ash 18.41% and water content 34.63% while sample 3 (75% Bio Degradable and 25% Degradable) was: calorific value 3041.53 Kcal/kg, ash content 13.62% and water content 37.33%. The test results for the briquette-type RDF product in the dry season had a calorific value of 4684.89 Kcal/kg, an ash content of 14.23%, and an ash content of 8.21%, in accordance with SNI 8966:2021 standards. Meanwhile, briquette-type RDF products during the rainy season do not meet SNI 8966:2021 standards, namely with a heating value of 4216.39 Kcal/kg, an ash content of 18.69%, and a water content of 22.02%. The results of the SPSS analysis show that the variables of waste type, composition, and season have a significant influence on the parameters of calorific value, ash content, and water content.
