Abstract

The goal of this work is the feasibility of biogas as a green energy source produced from organic matter from ruminants, equine and farming activities in the central part of South Sulawesi. The study was conducted with survey and laboratory analysis to calculate the number of ruminants, corn, and rice stalk using supporting data from the South Sulawesi Statistics office. Amounts of 84,567, 112,915, and 3,579 ruminants have been raised in Maros, Gowa, and Makassar, respectively. While 6,757, 9,529, and 50 monogastric are raised in Maros, Gowa, and Makassar. Corn and rice stalks were produced 465,878.06 tons year-1 in Gowa and Maros. Every cattle and equine can produce feces up to 25 kg day-1 and 30 kg day-1, daily feces production equals 2,316,885; 3,108,745; and 90,975 kg day-1 in Maros, Gowa, and Makassar, respectively. These waste products can be converted to biogas as source of green energy with a total yield of 667,752,675,489.20 x 103 cc. Its production ratio is 1 kg dry matter: 1,051.3-liter biogas for beef feces and 1 kg dry matter: 3,980-liter biogas for equine feces and corn and rice stalks can be applied as organic fertilizer as a significant factor in anaerobic fermentation of biogas production.

Highlights

As European Commission has launched a “The green new deal”, this set of policy has inspired many countries globally to deal with climate change and set a climate neutral target by 2050 [1,2], many Asian countries such as Indonesia as well as has set similar target
The objective of this work was aimed to approximate the potential of biogas production from both of animal manure such as ruminant as well as monogastric and other organic matter such as corn and rice stalk in three parts of South Sulawesi Indonesia
Deploying organic matter from farming practices such as corn and rice stalk could enhance biogas production in anaerobic fermentation considering that those stalks have high C/N ratio that play a key role on generating methane (CH4) inside of anaerobic digester [22]

Summary

Introduction

As European Commission has launched a “The green new deal”, this set of policy has inspired many countries globally to deal with climate change and set a climate neutral target by 2050 [1,2], many Asian countries such as Indonesia as well as has set similar target This in line with The Intergovernmental Panel on Climate Change (IPCC) which suggest that by 2050 up to 77% of energy utilization has to be supplied from green energy [3]. Animal manure as well as corn and rice stalk has huge potential as raw material of biogas production as a green energy source due its abundance of cellulose ingredient [9]. The objective of this work was aimed to approximate the potential of biogas production from both of animal manure such as ruminant (cattle) as well as monogastric (equine) and other organic matter such as corn and rice stalk in three parts of South Sulawesi Indonesia
