Kepok and Raja banana are type of banana plant that is most consumed and widely planted in Indonesia, especially Riau. Banana stem is a part of the banana plant that is generally used as animal feed or just thrown away. It can be an environmental problem through the emission of foul odours when it is left to decompose. Banana stem contain 27.8% lignin; 43.3% cellulose and 20.6% hemicellulose. P…
Fly ash is one of the by-products of a palm oil mill. Fly ash contains silica which can be used as a raw material for zeolite synthesis. ZSM-5 has been synthesized through the alkali-hydrothermal fusion method. Synthesis is done by first calcining palm oil fly ash at a temperature of 700oC for 6 hours, then dissolving it in 1N hydrochloric acid and filtering it. Fly ash is then washed with dist…
