Production of Biogas from Organic Fruit Waste in Anaerobic Digester using Ruminant as The Inoculum

Abstract

Abstract. Organic waste, fruit waste and vegetable waste are the best substrate to produce biogas. Waste management system for producing biogas can be used as a solution with the waste problem by converting the wastes into biogas. This study is expected to review of the effect of substrate type and substrate composition for the volume of biogas produced. In this study, materials consist of fruit wastes (oranges, apples, papayas, and tomatoes), cow ruminant, urea, cow dung, Na 2 CO 3 buffer, NH 4 HCO 3 buffer, and distilled water with variations of the substrate materials, F/ W, and the buffer types. The addition of cow manure and Na 2 CO 3 buffer with 1:2 of F/W, production of biogas is greater than variable which is used NH 4 HCO 3 buffer and without the addition of cow dung. Variables with addition of cow dung with 1:1 of F/W and using Na 2 CO 3 buffer, the result is greater than the variable using the same buffer but without the addition of cow dung and variables with 1:1 of F/W with the addition of cow dung and Na 2 CO 3 buffer and variables with the same feed and without the addition of cow dung produce more biogases than variable which is the using NH 4 HCO 3 buffer, 1:1 of F/W and without the addition of cow dung.

Biogas Production from Coffee Pulp and Chicken Feathers Using Liquid- and Solid-State Anaerobic Digestions

“…According to research conducted by Saragih et al, the solubility decreased as the percentage of TS increased, which affected the solid substrate's mass transfer, such that the higher the solubility, the better the microbes' ability to degrade the COD [30]. Reduced COD levels in anaerobic digestion indicate that materials other than acids can be degraded because organic acids in the liquid phase increase COD [31]. The substrate residence time According to research conducted by Saragih et al, the solubility decreased as the percentage of TS increased, which affected the solid substrate's mass transfer, such that the higher the solubility, the better the microbes' ability to degrade the COD [30].…”

Pengaruh Total Solid dan Perbandingan Bahan Baku dengan Inokulum terhadap Produksi Biogas dari Jerami Jagung

“…BBM merupakan bahan bakar fosil yang tidak bisa diperbarui, jika digunakan terus menerus akan habis. Oleh karena itu dibutuhkan energi alternatif yang dapat diperbaharui sebagai pengganti BBM [1]. Salah satu energi yang dapat diperbaharui adalah biogas.…”

“…Keunggulan dari biogas ini adalah ramah lingkungan karena bahan baku berupa limbah organik, misalnya limbah hasil pertanian, limbah buah-buahan dan limbah sisa makanan. Beberapa penelitian terkait biogas sudah pernah dilakukan diantaranya, Budiyono et al [1] meneliti tentang pengaruh jenis inokulum terhadap produksi biogas dari sampah buah-buahan. Inokulum yang digunakan adalah rumen sapi.…”

A comparative analysis of biogas production from tomato bio-waste in mesophilic batch and continuous anaerobic digestion systems

“…Nowadays, most studies focus on utilizing tomato crops, seeds, and peels for biogas production or carotenoid extraction. Many studies investigated the utilization of various kinds of tomato waste, such as those from groceries, processing plants, tomato sauce, and tomato puree [22][23][24][25][26]. There are only few reports on the bioenergetic utilization of stems and leaves from tomato wastes [7,[26][27][28][29].…”
