Abstract
Indonesia is an agrarian country where farming is the main occupation of its people. Therefore fertiliser becomes an indispensable item. At present, the majority of fertilisers are met by chemical fertilisers. The low content of micronutrients in chemical fertilisers causes quality degradation to the chemical, physical, and biological properties of the soil. Organic fertiliser is one of the strategic solutions to overcome these problems. Agricultural and livestock waste, including coconut husk, goat manure, and chicken excreta can be used as raw material for liquid organic fertiliser. Experiments were comparing various compositions of coconut husk used, namely 0, 0.65, 1.25, 2.5, and 5%. The analysis design used is One-Way Anova. Fermentation was carried out for one week in anaerobic conditions. Ammonium, nitrate, and nitrite levels of bioculture with the addition of 5% young coconut husk were significantly higher than other treatments, obtained values, 0.193; 0.705; and 0.523%, respectively. The bioculture made has met the quality of liquid fertiliser as in Standar Nasional Indonesia (SNI).
