Processing waste with an open pond is indeed able to reduce the levels of organic matter in liquid waste through the fermentation process of these organic materials by the bacteria forming methane. However, the by product of the fermentation process produces methane and carbon dioxide which can increase the concentration of Greenhouse Gases (GHG), which causes global warming. This study aims to determine the success of palm oil wastewater treatment process based on Methane (CH4) and Carbon dioxide (CO2) emissions at PT. Perkebunan Nusantara XIV, East Luwu Regency.
Data analysis techniques using laboratory tests which then calculate emissions using a formula adopted from the International Atomic Energy Agency (IAEA) to determine the value of gas emissions emitted from ponds of WWTP PT. Perkebunan Nusantara also analyzes sources of organic matter on wastewater with using laboratories.
The results showed that the concentration of methane gas and carbon dioxide produced from each WWTP pool varied, this was due to the decrease in the number of different COD values in each WWTP pond which was also influenced by the pool characteristic and the amount of mud in the pond. The highest value of methane gas emissions occurred during the daytime at pool 2 (anaerob) of 4314.74 x 103 mg m-2min-1 and pond 6 (sedimentation) of 1235.93 x 103 mg m-2min-1 and the emission value needed occurred in pond 4 (Aerob) in the afternoon at 24.23 x 103 mg m-2min-1 and the highest value of carbon dioxide emissions in pond 1 (Anaerob) during the day is 7111.83 x 103 mg m-2min-1 and the smallest emission value in pool 4 during the day is 280.09 x 103 mg m-2min-1. Total penurunan nilai COD pada kolam anaerob sekitar 79.19 % dan kolam sedimentasi adalah 58 %. Dimana, setiap penurunan 1 mg COD akan menghasilkan 0,45 kg/m-2 gas metana.
