CHANGES IN LIGNOCELULLOSIC CONTENTS OF OIL PALM EMPTY FRUIT BUNCHES PRETREATED WITH WHITE-ROT FUNGI

Oil Palm Mill Waste

Indonesia today is a biggest producer of CPO (crude palm oil) in the world and has the largest palm oil plantation in the world. Palm area in Indonesia in 2007, according Dirjenbun, Department of Agriculture, estimated to reach 6.6 million ha and the production of CPO in the year reached 17.3 million tons. The area and production is expected to continue to rise given the current intensively conducted slowly opening new oil, especially in the island of Kalimantan and Papua.

Mushrooms on OPEFB (Oil Palm Empty Fruit Bunches) Pile

dsc_2910_bSome time ago I visited one of the oil palm plantation in Palembang. Area of palm oil palm plantations is not too large, approximately 8000 ha (core plantation) and 40,000 ha (plasma). Fresh fruit bunches (FFB) harvested from the plantation is then processed in the palm oil mill near at one end of the garden. Factory processing capacity currently approximately 50 tons of FFB / hour. From the processing of FFB produced CPO (crude palm oil), waste OPEFB (oil palm empty bunches), and liquid waste. OPEFB waste volume large enough, in one day can reach 150 tons.

Potensi Bioethanol dari Biomassa Lignoselulosa

Limbah lignoselulosa memiliki potensi besar sebagai bahan baku bioethanol. Sebagai contoh dari 1 ha sawah dapat diproduksi sebesar 766 hingga 1.148 liter bioethanol. Jika harga ethanol sekarang adalah Rp. 5.500,- maka nilainya adalah Rp. 4,210 juta hingga Rp. 6,316 juta. Jumlah yang tidak sedikit.

Ethanol dari Jerami Padi

Jerami padi mengandung kurang lebih 39% sellulosa dan 27,5% hemiselullosa. Kedua bahan polysakarida ini dapat dihidrolisis menjadi gula sederhana yang selanjutnya dapat difermentasi menjadi ethanol. Potensi produksi jerami padi per ha kurang lebih 10 – 15 ton, jerami basah dengan kadar air kurang lebih 60%. Jika seluruh jerami per ha ini diolah menjadi ethanol (fuel grade ethanol), maka potensi produksinya kurang lebih 766 hingga 1,148 liter/ha FGE (perhitungan ada di lampiran). Dengan asumsi harga ethanol fuel grade sekarang adalah Rp. 5500,- (harga dari pertamina), maka nilai ekonominya kurang lebih Rp. 4,210,765 hingga 6,316,148 /ha. Lumayan besar juga.
