Pengaruh Aktivator Effective Microorganism 4 Terhadap Proses Pembuatan Pupuk Organik dari Kotoran Sapi

Abstract

Cow's excrements originated from slaughterhouse is an organic waste that can damage the environment
therefore need to be process to make something such as fertilizer using activators that help the
decomposition process run faster. Activator used in this experiment is Effective Microorganism 4.
Decomposition of cow’s excrements becoming organic fertilizer by mixing cow’s excrements with Effective
Microorganism 4 activator. Ratio of cow’s excrements weight (Metric Ton) by volume (Liter) of Effective
Microorganism 4 activator is 1:0; 1:1; 1:2; 1:3; 1:4. Thereafter, add the anorganic fertilizer (Urea, KCl,
SP-36) and limestone to the mixture each about 2,5 kilograms after that cover the mixture with plastic wrap
and make some holes with bamboo. The experiment result for this study using Effective Microorganism 4
activator by adding 4 liter in the decomposition process for 18-21 days to produce organic fertilizer consist
about 15,01% organic carbon, 0,87% total nitrogen, 17,25 C/N ratio. These result meet the quality
standards set by the Minister of Agriculture No.70/Permentan/SR.140/10/2011.
