Abstract

Methyl esters derived from coconut oil are very interesting to study because they contain free fatty acids , so most methyl esters (70%) can be bio-kerosene and the rest can be biodiesel. Trans-esterification triglyceride generally using a homogeneous KOH catalyst but this process requires a long catalyst separation process through washing and drying process. The use of heterogeneous catalysts in the production of methyl esters can remove the washing and drying processes, but trans-esterification reactions with heterogeneous catalysts require severe conditions, whereas at low temperatures and atmospheric conditions, the methyl ester yield is relatively low. Using microwave-irradiated trans-esterification reactions with heterogeneous catalysts, it is expected to be much faster and can obtained higher yields. Therefore, in this study we prepare a heterogeneous catalyst K/γ-Al2O3 using solution KOH that impregnated in catalyst support γ-Al2O3, and catalyst obtained are characterized by XRD, BET dan SEM. Our objective was to compare the yield of methyl esters obtained through the trans-esterification process of coconut oil assisted by microwave using a heterogeneous K/γ-Al2O3 catalyst with yield obtained using a homogeneous KOH catalyst. The batch process was carried out at atmospheric pressure with variation of K/γ-Al2O3 catalyst concentration (0.5, 1.0, 1.5, 2.0, 2.5%) and microwave power (100, 264 and 400 W). The experimental results show that the methyl ester yield increases with increasing of microwave power, catalyst concentration and reaction time. However, the yield of methyl esters obtained by the K/γ-Al2O3 heterogeneous catalyst process are relatively easy to separate rather than using a homogeneous KOH catalyst.

Abstract

Bioetanol merupakan salah satu alternatif untuk mengurangi penggunaan bahan bakar minyak, atas dasar tersebut maka dilakukan penelitian untuk membuat bioetanol dari bahan baku yang mengandung lignoselulosa seperti kulit singkong dengan melihat pengaruh konsentrasi enzim silanase dan jumlah ragi. Metode yang digunakan dalam penelitian ini yaitu sakarifikasi dan fermentasi serentak dengan menggunakan dua variabel. Variabel pertama, konsentrasi enzim silanase yaitu 30, 50 dan 75 unit. Variabel kedua, jumlah ragi Saccharomyces Cerevisiae yaitu 5% dan 10% b/v. Proses pertama dilakukan persiapan sample dengan mengeringkan dan menghaluskan sample, setelah itu dilakukan proses delignifikasi untuk mengurangi kadar lignin dan dilanjutkan dengan metode sakarifikasi dan fermentasi serentak, proses sakarifikasi dilakukan selama 18 jam dan fermentasi selama 96 jam. Hasil akhir dianalisa menggunakan kromatografi gas. Hasil yang diperoleh pada pemakaian enzim 75 unit dengan jumlah ragi 10% merupakan hasil dengan kadar etanol tertinggi yaitu 3.018% sedangkan kadar etanol terkecil diperoleh dari hasil pemakaian enzim 30 unit dengan jumlah ragi 5%. Dari data yang diperoleh dapat terlihat bahwa pemakaian enzim tertinggi menghasilkan kadar etanol yang tinggi pula, begitu juga dengan jumlah ragi Saccharomyces Cerevisiae 10% menghasilkan kadar etanol yang lebih tinggi daripada jumlah ragi 5%.
