Ketergantungan terhadap bahan bakar fosil ini menjadi masalah besar yang sangat mendesak untuk segera diselesaikan. Salah satu langkah solusi yang bisa dilakukan adalah memanfatkan bioetanol lignoselulosa dari limbah kulit singkong sebagai alternatif pengganti. Permasalahan utama yang menghambat penggunaan kulit singkong sebagai bahan baku utama pembuatan bioetanol adalah belum adanya proses pretreatment dan hidrolisa yang terbukti efektif secara teknis maupun ekonomis untuk mengkonversi lignoselulosa yang terkandung dalam kulit singkong menjadi bentuk gula sederhana. Penelitian ini dilaksanakan untuk mengetahui efektifitas proses pretreatment dan hidrolisa untuk mengkonversi lignoselulosa yang terkandung dalam kulit singkong menjadi bentuk gula sederhana. Metode pretreatment asam (H2SO4) dan organosolv (Etanol + CH3COONa) terbukti dapat meningkatkan yield gula tereduksi hingga 50% dibandingkan dengan proses hidrolisa tanpa pretreatment. Yield hingga 78% dapat diperoleh pada proses pretreatment asam suhu 30oC, waktu 30 menit yang dilanjutkan dengan hidrolisa enzimatik dengan Aspergillus niger selama 48 jam. Peningkatan yield pada proses pretreatment organosolv (optimum 74% pada suhu 30oC, waktu 90 menit) masih dapat dilakukan dengan meningkatkan waktu operasi dan meningkatkan suhu operasi. Namun peningkatan suhu maupun penambahan waktu operasi berpengaruh terhadap analisa teknis dan ekonomis dari proses. Secara teknis, pretreatment organosolv lebih mudah dilakukan terutama pada proses dengan kondisi operasi atmosferik dibandingkan dengan pretreatment asam karena sifat bahan kimia yang digunakan dan penanganannya. Secara ekonomis, pretreatment asam lebih baik untuk diaplikasikan dibandingkan pretreatment organosolv, hal ini dikarenakan yield yang dihasilkan lebih tinggi pada kondisi proses atmosferik.Â Lignocellulose material derived from cassava peel can be utilized as raw material for bioethanol production. The utilization of this material can be part of solution in order to maintain Indonesiaâ€™s energy security which still majority covered by the fossil fuel. The main problem of lignocellulose conversion into bioethanol is their crystalline structures those make them really difficult to be converted into monomeric sugar prior fermentation to produce ethanol. The objective of this research is to find out the effectiveness of pre-treatment process prior enzymatic hydrolysis of lignocellulose contained on cassava peel. The result shows pre-treatment methods both acid (H2SO4) and organosolv (Etanol + CH3COONa) proved to be effective in order to increase the yield of total reducing sugar (TRS) until 50% after enzymatic hydrolysis compared to the sample without pre-treatment. Highest yield 78% can be achieved by applying acid pre-treatment under temperature 30oC and 30 minutes of process prior enzymatic hydrolysis by Aspergillus niger under temperature 35oC for 48 hours. Further optimization in organosolv pre-treatment can be conducted by increasing the temperature and prolong the process into certain extent. It should be noted that the above action could influence the feasibility of the organosolv pre-treatment technically and economically. From technical point of view, organosolv pre-treatment can be more feasible compared to acid pre-treatment (under atmospheric condition) as the reagents are easy to handle in terms of safety consideration. However, from economic side acid pre-treatment is more preferable as higher yield of the process and lower volume of chemical can be used in order to achieve the same amount of product.Â

Absract Existence of paper in human life is important, because paper has function to record science, commerce promotion, medium to extend opinion and idea, and etc. However substance of paper in this time is become thin. For that, we try making pulp from waste of cornâ€™s stem with use soda process and the tool is digester. The colour of product pulp is brown, but after the washing the colour pulp is shine brown because of impurity in the pulp is solute after been washed. The pulp is analyzing more further, between bleaching process, analyses of number permanganate, analyses grade of a cellulose, and grade of ash. The colour of product pulp after bleaching is white brown, grade of Î± cellulose 48.32%, grade of ash 8.8%, number permanganate 8.184. Â Key word : cornâ€™s stem, soda process, bleaching

Meningkatnya harga bahan bakar dan menurunnya cadangan bahan bakar fosil memaksa untuk mencari sumber-sumber energi yang murah sebagai biofuel, seperti bioetanol dapat mengurangi efek negatif dari penggunaan bahan bakar fosil yang tidak terbarukan. Bioetanol dapat terbuat dari biomassa yang mengandung gula, pati dan selulosa. Dedak padi merupakan hasil samping dari penggilingan padi dan menyumbang Â±11% dari berat padi. Dalam hal ini dedak padi karbohidrat yang cukup tinggi untuk diolah menjadi bioetanol. Sementara untuk meningkatkan kadar etanol, proses terpenting dalam produksi bioetanol adalah proses fermentasi. Tujuan dari penelitian ini yaitu pengoptimalan proses fermentasi meliputi pH dan waktu pada pembuatan bioetanol dari ekstrak dedak padi dengan penambahan urea dan NPK sebagai sumber nutrisi untuk pertumbuhan saccharomycess cerevisiae. Penelitian ini menggunakan dedak padi yang dihidrolisis, kemudian difermentasi menggunakan saccharomycess cerevisiae dengan penambahan nutrisi urea dan NPK, dan di distilasi untuk dimurnikan. Pengoptimalan pH dan waktu pada proses fermentasi serta penambahan nutrisi urea dan NPK diharapkan mampu meningkatkan kadar bioetanol yang dihasilkan. Hasil data dihitung dengan menggunakan metode perhitungan faktorial desain untuk mengetahui variabel paling berpengaruh.Â Â Rising fuel prices and declining fossil fuel reserves force to find cheap energy sources as biofuels, such as bioethanol can reduce the negative impact of using non-renewable fossil fuels. Bioethanol can be produced from biomass containing sugar, starch and cellulose. Rice bran is a by product of rice milling and accounts for Â±11% of the weight of rice. In this case the carbohydrate rice bran is high enough so that it can be processed into bioethanol. Meanwhile, to increase ethanol content the most important process in manufacture of bioethanol is fermentation process. The purpose of this study is to optimize the fermentation process including pH and time in manufacture of bioethanol from rice bran extract with addition of urea and NPK as a source of nutrients for growth saccharomycess cerevisiae. This study used rice bran which was hydrolyzed, then fermented using saccharomycess cerevisiae with addition of urea and NPK nutrients, and then distilled to be purified. Optimizing pH and time in the fermentation process as well as adding urea and NPK nutrients are expected to increase levels of bioethanol produced. The results of the data are calculated using the design factorial calculation method to determine the most influential variable.
