Quality of Organic Fertilizer Due to Material Combination with Bio-activator

Abstract

Litters or pine cage mats are very good at absorbing water and odours from broiler chicken manure. Pine-based litter takes a long time to decompose. Therefore, this study was conducted to find out how the waste was processed into compost using a combination of materials and levels of EM-4 bioactivator. This study used litters of chicken, pine wood waste and water hyacinth with the addition of a different EM-4 bioactivator. The research design used was a completely randomized factorial design (CRFD) consisting of 2 treatment factors with 3 replications. Treatment A was a combination of ingredients used: A0= 100% litter of chicken; A1= 70% litters of chicken, 15% pine sawdust, 15% water hyacinth; A2 = 55% litter of chicken, 30% pine sawdust, 15% water hyacinth; A3=40% litter chicken, 45% pine sawdust 15% water hyacinth. Treatment B level of bioactivator: B1=1% and B2=2%. The parameters observed were pH (degree of acidity), humidity, temperature, and C/N ratio in organic fertilizers. The data obtained were analyzed using Analysis of Variance (ANOVA) and if the results of the analysis showed an effect, it was continued with the Duncan Multiple Range Test. The results showed that Factor A in the treatment had a significant effect on the degree of acidity (pH), humidity and temperature, but had no effect on the parameters of the C/N ratio at 6 weeks of composting. Factor B did not show any effect on all parameters at the same composting time. The conclusion is that the combination treatment of materials and bioactivator levels has not been able to reduce the C/N ratio with a composting time of 6 weeks, so it is recommended to use a longer time.
