KADAR UNSUR HARA NITROGEN (N) DAN FOSFOR (P) PADA PUPUK KOTORAN AYAM PETELUR YANG DIKOMBINASI DENGAN BERBAGAI LIMBAH BAHAN ORGANIK DENGAN SISTEM DRUM PUTAR

This study aims to determine the effect of the addition of organic waste on the N and P levels of laying hen manure fertilizer with a rotary drum system. The material of this research is laying hen manure from open house cages that have accumulated for one month. The research method uses the experiment/experimental method, while the research design uses the Complete Random Design (RAL). Treatment: P0 = 100% laying hen droppings, P1 = 50% laying hen droppings + 50% coffee husks, P2 = 50% laying hen droppings + 50% banana peels, P3 = 50% laying hen droppings + 50% husk ash with 3 repeats using descriptive analysis. The results of this study showed that the addition of organic matter waste had a very real effect (P< 0.01) on N levels, the research data was analyzed with ANOVA, and continued with the Duncan test, the highest N content value in compost plus banana peels was 1.47% and coffee husks was 1.44%, while the analysis of Anova P levels of laying hen manure had no real effect (P>0.05). This value has met the RSNI3 7763:2024 standard. The variables measured are N levels and P levels. The conclusion is that the average results of the addition of banana peel and coffee peel can increase the N level in chicken manure fertilizer, but the addition of coffee peel waste, banana peel and husk ash does not have a real effect on increasing the P level in chicken manure.
