Abstract

Environment is now an important global current issue and as a factor thatmust be considered in the implementation of Indonesian nationaldevelopment. Entering globalization era, the condition of environment willbe one of the parameters required for a country to be accepted in theworld free trade community. Instead, a country with bad environment cantherefore be charged for a penalty, such as a limited export quota. Forthat reason, starting now, Indonesia should improve their environmentalcondition by implementing a good environmental management in order toattain the standard of a good environment. If Indonesia cannot achievethis goal, Indonesia will be used by other countries as their big market,without the ability of Indonesia to export their products. If the standard hasbeen fulfilled, Indonesia can be part of the world free trade community inwhich this is a benefit for Indonesia itself. Without lowering the pace ofdevelopment growth, national development through holistic environmentalmanagement would be a proper program to implement. This program isconsidering the impact of development to the environment and thisprogram was commencing by the Indonesian government since 1970.However, it seems that the holistic environmental development has notbeen running smoothly, especially at the soft sides of development, suchas people awareness, environmental law, law enforcement, arbitrarycommittee, community development, environmental information includingpeople rights to get those information, the role of non-governmentorganization, etc.By considering the importance of environmentaldevelopment in a holistic way to fulfill the globalization requirements, thispaper would be focused on the factors that may inhibit the nationaldevelopment. Those are factors that affect sustainability of environmentalfunctions. Solution to the problems may also generally be described.

Abstract

ABSTRACT Palm Oil Mill Effluent (POME) resulted from the palm oil industry is a potential resource for biogas production. In this study, POME was processed by utilizing microbes in an anaerobic condition using a fixed bed reactor. This study aimed at providing alternative processing of POME into biogas at the most optimum biogas yield without any pretreatment, taking advantage of POME conditions generated from the production process at the average temperature of 55 – 60 °C. In the anaerobic process, temperature conditions have a significant effect on bacteria's performance to degrade organic matter. In thermophilic conditions, bacteria deteriorate organic substrates more actively than in mesophilic states. This research proved that using fixed bed reactor technology to treat POME without pretreatment has generated biogas at the yield of 25.43 liters/liter of POME production. Applying this technology also demonstrated that investment and operating costs are cheaper due to having no mixing tank and fewer chemicals applications for the neutralization process. Keywords: biogas, fixed bed reactor, POME, pretreatment, thermophilic   ABSTRAK Proses pengolahan POME dapat dilakukan dengan menggunakan proses fermentasi anaerobik yaitu memanfaatkan kerja bakteri anaerobik untuk memproduksi biogas. Penelitian ini bertujuan memberikan alternatif pengelolaan limbah cair pabrik kelapa sawit yang dapat menghasilkan biogas yang paling optimal tanpa melakukan pretreatment. Proses yang dipilih disesuaikan dengan kondisi panas POME yang keluar proses yaitu sekitar 55 - 60 oC. Kondisi temperatur sangat berpengaruh nyata terhadap kinerja bakteri pendegradasi bahan organik di dalam limbah cair dalam proses anaerobik. Pada kondisi termofilik bakteri lebih aktif dibandingkan pada kondisi mesofilik. Melalui penelitian ini, dapat diketahui bahwa dengan menggunakan teknologi reaktor fixed bed untuk mengolah POME tanpa adanya pretreatment, biogas tetap dapat diperoleh dengan perolehan rata rata 25,43 liter per liter POME. Dengan menggunakan teknologi ini biaya investasi dan operasi akan lebih murah dikarenakan tidak memerlukan bak pencampur dan penggunaan bahan kimia untuk proses netralisasi. Kata kunci: Biogas, reaktor fixed bed, POME, pretreatment, termofilik
