Financial analysis of biogas utilization : input cattle, pig feces and coffee waste in Karo, Indonesia

Abstract

Abstract. The community's need for renewable energy was very urgent. In addition, efforts to preserve the environment from waste caused biogas technology feasible to apply. This study aims to provide biogas technology with minimal cost and utilize agricultural waste that were coffee and livestock waste. The study was conducted from July to October 2016. The theoretical and empirical methods used in this study were included data from officials resources, field survey on 16 biogas locations, focus group discussion and interview with stake holders. Data were tabulated by Excel Program which then were analysed by SAS. Parameters were included Production Cost, Production Result, Profit Loss Analysis, Revenue Cost Ratio (R/C Ratio), Return On Investment (ROI), Net B/C, and IRR.The result of this research showed that the application of bioplastic gas with cow dung and coffee waste as bioplasticgas input cause the best results.

How Do Agricultural Biogas Investments Affect Czech Farms?

“…Agricultural biogas plants are often criticised in terms of their suboptimal use of public funds and their adverse environmental impacts on soil quality. By evaluating the effects of biogas investments on the economic sustainability of farms, including the probability that farms will go bankrupt, this article fills a gap in the economics literature, which has hitherto concentrated on the partial economic effects of agricultural biogas plants based on case studies which do not yield generalisable results (Ginting et al, 2018;Sgroi et al, 2018;Vochozka et al, 2018). By contrast, this article utilises data from a representative sample of biogas plants in the Czech Republic.…”

Evaluación de los co-beneficios ambientales y económicos del aprovechamiento energético de las excretas porcinas

“…La mayoría de los artículos relacionados con el tema de biogás y energía reportan datos económicos principalmente en procesos a pequeña escala en zonas rurales (Surendra et al, 2014;Rupf et al, 2015;Abbas et al, 2017;Garfi et al, 2017;Yasar et al, 2017;Mittal et al, 2018). En general, se menciona sobre los beneficios económicos que tienen los procesos por el ahorro de la energía y la sustitución de fertilizantes minerales para recuperar los costos de capital, pero no concluyen sobre la viabilidad económica, sólo algunos de ellos han reportado rentabilidad de los procesos (Abbas et al, 2017;Garfi et al, 2017;Ginting et al, 2018). Sin embargo, la mayoría coinciden que sin incentivos económicos gubernamentales los proyectos de biogás no son económicamente viables (Mwirigi et al, 2014;Mittal et al, 2018).…”
