Abstract

Jumlah timbulan sampah di FSM, FIB dan D3 Teknik mencapai 0,08 kg/orang/hari dengan sumber sampah gedung, taman/jalan, dan kantin. Jumlah sampah yang dapat digunakan sebagai bahan untuk pengomposan dan briket bioarang adalah FSM 944,61 L, FIB 127,06 L, dan D3 Teknik 101,07 L. Hasil uji karakteristik sampah didapatkan nilai kadar air FSM 36,6% FIB 28,79 % dan D3 Teknik 50,58 % . Nilai kadar abu FSM 10,5% , FIB 4,35%, dan D3 Teknik 4,09%. Rasio C/N untuk FSM  27,45 : 1, FIB 30,7 : 1 dan D3 Teknik 30,4 :1. Kadar kalori dari sampah FSM 4.089 kkal/kg, FIB 4.274 kkal/kg, dan D3 Teknik 3.743 kkal/kg. Rumus empiris sampah organik (sisa makanan dan daun) di FSM C222H477O221N7S, FIB C242H513O237N7S, dan D3 Teknik C210H446O206N6S. Pada penelitian ini berdasarkan hasil timbulan, komposisi, dan karakteristik sampah yang dihitung di FSM, FIB dan D3 Teknik , kemudian dihubungkan dengan standar karakteristik sampah dari berbagai referensi didapatkan hubungan timbulan, komposisi dan karakteristik sampah terhadap metode pengolahan secara anaerobic digestion, pengomposan, briket bioarang, insenerasi dan recycle.   Kata kunci: analisis karakteristik, pengolahan, kompos, sampah, timbulan.

Abstract

The drainage system in the Kedungmundu Road area has several channels that can no longer accommodate the rainwater discharge, resulting in runoff of rainwater in the drainage channel, which causes flooding and puddles of rainwater in the Kedungmundu Road Area. Drainage in the Kedungmundu Road area has problems such as silting channels due to garbage, soil sedimentation, and insufficient channel dimensions. In the hydrological analysis, the rainfall intensity is 129,586 mm/hour. As the hydraulic analysis, the drainage channel is normalised by dredging sediment in the channel. If there is still rainwater runoff, additional channel dimensions are carried out, taking into account the existing conditions that only Karanggawang Lama road, H. Abdurochman road, and Kedungmundu Lama road changed. Channel dimensions, while for other channels, it is not possible to change the channel dimensions for that, it is necessary to apply SUDS. The Sustainable Urban Drainage System, or in SWMM 5.1 called Low Impact Development, is carried out using rainwater harvesting (Rain Barrel) and Permeable Pavement. The recapitulation of the application of the LID concept in the planning area is known to cover an area of 8.3 hectares of the total planning area of 54.48 hectares. This LID concept can reduce the total runoff value in each sub-catchment, thereby reducing the amount of rainwater discharge that enters the drainage channel with a percentage decrease in the average total runoff value of 19%. The Budget Plan needed to rehabilitate canals and dredging sediments and implement the Sustainable Urban Drainage System (SUDS) is around IDR 5,405,300,000.
