Utilizing Cattle Livestock Waste for Biogas Energy Production in Barito Kuala Regency, South Kalimantan

Abstract

Farmers have traditionally used livestock waste, such as feces or urine, in a limited capacity as organic fertilizer. Biogas can be generated from this waste and used as a long-term source of renewable energy. The research purpose is to determine the use of beef cattle waste as a source of energy via biogas in tidal land, with a case study in Barambai and Rantau Badauh Districts, Barito Kuala District, South Kalimantan. A survey was conducted in September 2018 in the villages of Kolam Kiri Dalam, Barambai District, and Danda Jaya, Rantau Badauh District, Barito Kuala Regency, which have a tidal agro-ecosystem and serve as a center for the development of the Bali cattle in intensive rearing system. The intensive maintenance system makes it simple to collect and use livestock waste. Since the manure has accumulated in the cage, making it easier to remove, this condition differs from others that are still semi-intensive and widespread. The result demonstrate that farmers gain benefit from biogas because livestock waste is utilized to prevent environmental pollution and they save Rp. 1,920,000 per family per year in Kolam Kiri Village and Rp. 1,530,000 per family per year in Danda Jaya Village. Farmers' assessments of economic and environmental factors strongly agree, and their assessments of social factors are quite agreeable and useful. Since biogas is expensive to built, it hasn't been widely adopted, but if the government offers financial assistance to farmers, they will adopt it.
