Abstract

Composter Engineering. The research method uses the treatment of the number of semi-anaerobic composter oxygen channels with 3 different oxygen holes. The results showed that the lowest temperature was obtained on repetition 1 for composter 6 holes with a temperature of 31.64°C and the highest for repetition 2 on composter 8 holes were 32.85°C. The lowest pH was obtained on repetition 1 for composter 10 holes with a pH of 5.66 and the highest for repetition 3 on composter 6 holes was 6.55. The results of the characteristics of compost fertilizer were obtained from the analysis of time, water content, phosphorus (P2O5), potassium, carbon, nitrogen, and C/N ratio. The conclusion was obtained, a semi-anaerobic composter was produced with 3 types of holes, namely 6 holes, 8 holes, and 10 holes with a composter tube capacity of 60 liters, having dimensions of 40 cm in diameter with a height of 60 cm and for the time the composter obtained the ideal compost was a composter with several holes the most is 10 holes with the results obtained which are 15-16 days compared to 6 holes 28 days and 8 holes 23 days. It is recommended to use materials that are not too wet which will inhibit the rate of decomposition and the presence of a pungent odor.

Abstract

Permasalahan utama di Desa Bukit Pamewa adalah kurangnya data tentang timbulan dan komposisi sampah. Masyarakat setempat biasanya membuang sampah di sungai, lahan kosong, atau membakarnya di pekarangan rumah. Selain itu, akses jalan juga belum memadai. Untuk mengatasi masalah ini, peneliti menggunakan metode deskriptif kuantitatif. Penelitian ini berfokus pada pengelolaan sampah di Desa Bukit Pamewa, Tuapejat, Kabupaten Kepulauan Mentawai, Sumatera Barat dengan tujuan utama adalah mengukur timbulan dan komposisi sampah. Metode sampling berdasarkan SNI 19-3964-1994. Penelitian ini menunjukkan timbulan sampah harian di Desa Bukit Pamewa adalah 8,49 kg/org/hari. Berdasarkan pengolahan data, timbulan sampah domestik adalah 7,50 kg/org/hari. Poskesdes menghasilkan 0,61 kg/org/hari, Posyandu 0,19 kg/m3/hari, Instansi Pendidikan 0,04 kg/org/hari, dan Instansi Pemerintahan 0,15 kg/org/hari. Komposisi sampah di Desa Bukit Pamewa didominasi oleh sampah organik sebesar 71%. Ini terdiri dari sisa makanan 40%, kertas 11%, sampah halaman 16%, dan kayu 5%. Sedangkan sampah anorganik sebesar 29% terdiri dari plastik 24% dan kaleng 5%.
