Pengaruh Nisbah C/N dalam Vermicomposting Campuran Ekskreta Ayam Petelur dan Serasah Dedaunan terhadap Perubahan Suhu, Jumlah Total Bakteri, dan Koliform

Abstract

The purpose of the study is to know the effect of C/N ratio in vermicomposting of chicken excrement mixture and foliage on the themperature changes, total number of bacteria and coliform and on the C/N balance that produces the lowest total coliform. Research was conducted using eksperimental methods, the complete randomized design consists of 3 treatment with different ratio C/N, P1(C/N 25), P2(C/N30), P3(C/N 35) which is repeated 6 times, Data were analyzed with the variance and continued with Duncan Test. The results showed that the C/N ratio balance in vermicomposting of the mixture of chicken excreta and leaf litter had a significant effect on the total number of bacteria, but had no significant effect on total coliform. The balance of C/N ratio of 30 resulted in the highest total bacterial count and the lowest coliform in the decomposition process of 80.67 x 10 11 cfu/g and 13,66 MPN/mL.
