Abstract

Mikroalga, seperti C. pyrenoidosa dapat digunakan sebagai bahan baku untuk produksi bioetanol generasi ketiga. Pemanfaatan karbohidrat mikroalga, seperti C. pyrenoidosa untuk produksi bioetanol memiliki tiga tahap utama, yaitu pretreatment bahan baku, hidrolisis, dan fermentasi. Penelitian ini bertujuan untuk mengetahui pengaruh hidrolisis asam dan waktu fermentasi pada proses pembuatan bioetanol berbahan baku C. pyrenoidosa. C. pyrenoidosa dihidrolisis menggunakan asam sulfat dengan konsentrasi yang bervariasi (1, 2, 3, 4 dan 5) % pada suhu 80oC selama 75 menit. Produksi bioetanol dilakukan dengan fermentasi glukosa menggunakan Saccharomyces cerevisiae dengan variasi waktu 1, 2, 3, 4 dan 5 hari. Hasil penelitian menunjukkan bahwa konsentrasi glukosa yang didapatkan mengalami peningkatan seiring naiknya konsentrasi asam sulfat dengan konsentrasi glukosa tertinggi, yaitu 5,97 gr/L didapatkan setelah hidrolisis menggunakan larutan asam sulfat 5%. Kadar bioetanol tertinggi, yaitu 19,28% diperoleh dari 5 hari fermentasi sampel hidrolisis 5% asam sulfat.

Abstract

Oil palm empty fruit bunches have a high lignocellulose content. Lignocellulose consists of hemicellulose, cellulose, and lignin. Lignin is the binder of cells in biomass. The structure of lignin is very complex and difficult to break down. The presence of lignin will hinder the processing of OPEFB and need to do delignification. One effective way to reduce lignin content is by ozonolysis. In this study, the effect of reaction time and oxygen flow rate on the OPEFB was studied. The reaction times in this process were 5, 10, and 15 min, and oxygen flowrates were 1, 2, 3 L/min. Lignin content was analyzed using the Kappa method. The least lignin content was obtained in the sample with 2 L/min flow rate for 5 min, which was 11.01% with a cellulose content was 64.72% and hemicellulose was 15.16%.

Abstract

Mango seeds (Mangifera indica L.) have a fairly high carbohydrate content and can be processed as an alternative food. This community service activity aims to educate the public about the process of processing mango seeds into flour and processed food ingredients. Prior to counseling, the team conducted initial experiments on the products produced using initial treatment in the form of soaking with water, slaked lime and sodium bisulfite. Organoleptic tests on processed food products from mango seeds were carried out by random respondents with assessment indicators in the form of color, texture, aroma and taste. The test results showed that processed cakes from mango seed flour as much as 30% with the initial treatment of sodium bisulfite immersion in the initial process had the best organoleptic value, namely, 3.7 out of 4. This activity was carried out at SMKN 1 Pemulutan and received very good appreciation because it was considered very useful, informative and can be developed continuously.
