NITROGEN LEVELS OF GOAT MANURE AND CHICKEN EXCRETA BIOCULTURE WITH ADDITION OF GRADUAL YOUNG COCONUT HUSK WASTE

Indonesia is an agricultural country where farming is the main occupation of its people. Therefore fertilizer becomes an indispensable item. At present, the majority of fertilizer used is met by chemical fertilizer. Long term application of chemical fertilizer and low content of micronutrients in common fertilizer causes quality degradation of the chemical, physical, and biological properties of the soil. Organic fertilizer 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 potential raw material for liquid organic fertilizer. The experiment was aimed to identify the best composition of coconut husk addition in liquid organic fertilizer. Various compositions of coconut husk used were 0; 0.65; 1.25; 2.5; and 5%. The analysis method was used One-Way Annova. 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, which obtained values 0.139; 0.705; and 0.523% respectively. The bioculture made has not met the quality of liquid fertilizer as in Standar Nasional Indonesi
