Tinjauan Penghilangan Fosfatida Pada Crude Palm Oil Menggunakan Metode Air Dan Asam Degumming Sebagai Bahan Baku Pembuatan Biodisel: Review Of Phosphatide Removal In Crude Palm Oil Using Water And Acid Degumming Method As Raw Material For Biodiesel Production
No full textSalah satu proses pemurnian minyak sawit mentah disebut proses degumming, proses ini menghilangkan gum yang terdiri dari beberapa pengotor yang tidak diharapkan untuk proses lebih lanjut. Salah satu pengotor itu ialah fosfatida, fosfatida terdiri dari fosfatida hydratable dan non hydratable. Penghilangan fosfatida ini lebih banyak dilakukan dengan metode water deguming, hanya saja water degumming tidak bisa menghilangkan fosfatida non hydratable, sehingga untuk proses penghilangan fosfatida non hydratable dilakukan dengan penambahan asam. Artikel ini menyajikan informasi terkait produksi biodisel, penghilangan fosfatida melalui metode water degumming dan acid degumming, serta pengaruh dari efektivitas penyisihan fosfatida terhadap produksi biodisel
Pemanfaatan Precipitated Calsium Carbonate (PCC) dari Limbah Cangkang Kerang Darah (Anadara Granosa) sebagai Adsorben Pengolahan Air Gambut
No full textPeat water is surface water which has a dark brown to black, has a very high organic content, and acidic. There are negative effects if used directly and continuously without processing. This is because in the peat water was found humic acidcompound that makes the peat water has these characteristics. One effort to decrease the concentration of humic acid is through adsorption method. The adsorbent that usded was precipitated Calisum Carbonate (PCC) which originate from waste shellsblood.Variable that was given in this research consisted by mass variation PCC 1, 3, 5, and 7, the stirring speed of 50, 100, and 150 rpm and a contact time of 15, 30, 45 and 60 minutes. The maximum state was reached on the mass of PCC 5 grams, stirring speed of 150 rpm, and a contact time of 30 minutes with the adsorption efficiency of 99.86% . Decreasing concentration of adsorption of organic substances (humic acid) of 1450 mg / L to 2,07 mg / L. From this research PCC is able to adsorborganic substances (humic acid) so that the results that was obtained accordingly with some parameters PERMENKES 416 / Menkes / PER / IX / 1990
Response surface methodology for glucose conversion by applying deep eutectic solvent (DES) as green solvent
No full textGlucose is a monosaccharide-type carbohydrate that serves as a fundamental building block of biomass. In this research, glucose was hydrolyzed using a Deep Eutectic Solvent (DES) as the solvent and AlCl3 as the catalyst. The effects of temperature and catalyst concentration were investigated as key variables in the reaction. The glucose conversion results were tested using the UV-Vis spectrophotometer. The yields of glucose conversion were analyzed using the Response Surface Methodology (RSM) with Design Expert Version 13 software. The results of RSM analysis show that glucose conversion increases linearly with rising reaction temperature. The effect of catalyst concentration indicates that glucose conversion decreases at higher catalyst levels. The reaction temperature and AlCl3 catalyst concentration that can be recommended for optimum conditions from the Design Expert data processing results are 112.869 C and 1.913% with a predicted conversion value of 93.844%
