Kajian Produksi Bio Listrik dengan Variasi Pupuk Organik pada Tanaman Pakcoy (Brassica rapa L.)

Abstract

The world's energy needs are increasing along with the rapid development of technology. This crisis has driven the need for alternative energy sources to produce renewable and environmentally friendly electrical energy. One alternative that could be developed was plant microbial fuel cells. This study was conducted to find out the best type of organic fertilizer in producing bioelectric. This study used a non-factorial Complete Random Design (CRD) on the variation of organic fertilizers in pakcoy plants. Treatment without fertilizer (P0) as control, organic waste fertilizer (P1), cow manure (P2), goat manure (P3), and chicken manure (P4). The results of the study showed that the variety of organic fertilizers had a very noticeable effect on the growth of microorganisms, current, voltage, power, and harvest index. The highest electrical power value in the organic fertilizer variety was found in P4 (chicken manure), which was 155.65 mW. The highest yield index of fertilizer variation was found in P1 treatment (organic waste fertilizer) which was 95.29%.
