The Effectiveness of the Addition of EM4 and Molasses in Increasing Levels of N, P and K in Environmentally Friendly Liquid Fertilizers Made From Banana Pseudostem

摘要

According to the statistics agency in 2017, banana production had the largest portion in Indonesia. Furthermore, banana production increased from 6.28 million tons to 7.04 million tons. Consequently, this tremendous production lead to an increasing of pseudostem waste. Through a re search-based community service program, empowerment of farmers, especially banana farmers, is carried out. One of area who farmers have been cultivating in East Java is in Pasuruan, namely Gondang Wetan village. This research examines the manufacture of environmentally friendly organic fertilizer using banana midrib as the main ingredient. Fertilizers are produced by using decomposers (EM4) as microbial decomposers. Moreover, fertilizers are distinguished in several variations in relation to the amount of preparation material. The fertilizer produced was further tested at the CV Nurti Techno Laboratory. As a results, the 12th sample (100 ml rice water: 100 gr banana pseudostem: EM4 3.0 ml: 3.0 ml mollase) has the highest composition of N (Nitrogen), P (Posphate), and K (Kalium), i.e. 0.076%, 0.32% and 0.47%, respectively.
