Composting method used passively aerated static pile system. The results showed that the compost characteristic of oil palm empty fruit bunch compost had a dark yellowish brown color, pH at 9.3, C/N ratio at 14, and nutrients (C-Organic, N, P, K, and Mn Total). The compost characteristics of grass had a very dark brown, pH at 7.3, C/N ratio at 7, and nutrients (C-Organic, N, P, K, and Mn Total). The compost from oil palm empty fruit bunch and grass were in accordance with the national standard of compost.Keywords: empty fruit bunch, grass, compos]]>
