摘要:Oil palm industrial waste has caused serious pollution to the environment, especially to the air environment, due to the release of Nitrogen oxide (N2O), methane (CH4) and carbon dioxide (CO2) gas. In addition to polluting the air, these three gases have caused global warming, which increased the average temperature of the earth's surface due to excessive concentrations of greenhouse gases. This study aims to analyze the effect of using Empty Fruit Bunches(EFB) compost on the cost of fertilizer use at PT Eastern Sumatra Indonesia, the effect of using EFB compost on productivity at PT Eastern Sumatra Indonesia and the effect of using EFB compost on GHG values at PT Eastern Sumatra Indonesia. This study uses secondary data. The data needed is the cost of using organic and inorganic fertilizers, oil palm productivity, GHG values from 2014-2019 per semester. The results showed that the use of EFB compost as organic fertilizer had a significant effect on the cost of using fertilizer at PT Eastern Sumatra Indonesia. However, it has no significant effect on productivity. Yet, the use of EFB compost as organic fertilizer has a significant effect on GHG values in PT Eastern Sumatra Indonesia..
