Abstract

Permasalahan yang hingga sekarang masih belum terselesaikan di Indonesia adalah sampah organik yang tiap tahunnya selalu mengalami peningkatan. Langkah yang dapat diambil untuk mengatasi permasalahan sampah adalah dengan pemanfaatan sampah organik sebagai bahan baku utama untuk Biogas dan pada proses start up digunakan kotoran sapi sebanyak 5 kg. Diperoleh data perbandingan antara air, sampah 1:1. Maka, diperlukan perancangan flow air yang akan masuk pada digester. Hasil dari kalibrasi didapatkan Ua1 (ketidakpastian pengukuran) = 0.016540178, Ua2 (ketidakpastian regresi) = 0.838979, Ub1 (ketidakpastian resolusi) = 0.00288675, Uc (ketidakpasian cakupan) = 0.1004271 dan UExp (ketidakpastian diperluas) = 0.20537341. Dihasilkan 44 detik ketika 3 kg sampah yang masuk dan 3 liter air yang masuk, 72 detik 5 kg sampah 5 liter air, 100 liter ketika 7 kg sampah 7 liter air. Rise time sebesar 38 detik, max overshoot sebesar 3,33%, peak time sebesar 38,2 detik, settling time sebesar 39,5 detik, error steady state sebesar 2.67%.

The problem that is still unresolved in Indonesia is organic waste which is always increasing every year. The steps that can be taken to overcome the waste problem is by using organic waste as the main raw material for Biogas and using the cow dung as much as 5 kg. Data comparison between water, garbage 1: 1 is obtained. So, it is necessary to design flow water that will enter the digester. The results of the calibration are obtained Ua1 (measurement uncertainty) = 0.016540178, Ua2 (regression uncertainty) = 0.838979, Ub1 (resolution uncertainty) = 0.00288675, Uc (coverage uncertainty) = 0.1004271 and UExp (expanded uncertainty) = 0.20537341. Generated 44 seconds when 3 kg of garbage enters and 3 liter of water enters, 72 seconds 5 kg of garbage 5 liter of water, 100 seconds when 7 kg of garbage is 7 liter of water. Rise time is 38 seconds, max overshoot is 3.33%, peak time is 38.2 seconds, settling time is 39.5 seconds, error steady state is 2.67%.
