Effective combination of palm oil plant waste and animal waste with bio-activator EM4 produces organic fertilizer

Abstract

In this paper, we produce a study with organic fertilizers from a combination of palm oil mill waste (POMW) and Cattle Waste (CW) in 3 schemes. More instance, first: K1 50% Palm Oil Mill Solid Waste (POMSW) + 50% Cow Cattle Solid Waste (CCSW), K2 50% Palm Oil Mill Solid Waste (POMSW) + 50% Cattle Liquid Waste (CLW) and K3 50% Palm Oil Mill Liquid Waste (POMLSW) + 50% Cow Cattle Solid Waste (CCSW) fermented with EM4 bio-activator and tested against sweet corn plants. Manwhile, the fertilizer doses tested for use are without fertilizer (Do), 10 tonnes/ha (D1), 20tonnes/ha (D2) and 30 tonnes/ha (D3) and the altitude of planting sites is lowland (T1), medium land (T2),  and highlands (T3). This research was conducted in Sei Mencirim Village, Suggal District, Sambahe Village, Sibolangit District, Deli Serdang Regency and Simpang Empat District, Karo Regency, respectively inNorth Sumatra Province. We run the statistical analysis by using a factorial randomized block design with three factors at once. In a nutshell. The simulation by K2 following 50% POMSW + 50% CLW is the recommended combination. At the same time, the dose of combination fertilizer is 20 tonnes / ha is the recommended dose and the plateau (T3) is a suitable place for planting corn.
