Pemanfaatan Limbah Kulit Singkong Menjadi Bioetanol Dengan Variasi Waktu Fermentasi

Di Indonesia konsumsi akan Bahan Bakar Minyak (BBM) mengalami peningkatan dari tahun ke tahun, hal ini berbanding terbalik dengan ketersediaannya. Bioetanol dapat dimanfaatkan sebagai pengganti bahan bakar minyak (BBM) tergantung tingkat kemurniannya. Tujuan dari penelitian ini: (i) untuk mengetahui pengaruh waktu fermentasi terhadap karakteristik bioetanol berbasis kulit singkong dan (ii) untuk mengetahui waktu fermentasi agar dihasilkan kadar bioetanol dengan karakteristik yang optimum. Pada penelitian ini Kulit singkong yang digunakan sebanyak 100 g, dengan proses pengeringan dijemur di bawah panas matahari selama 1 hari. Tahap selanjutnya hidrolisis menggunakan Aquades sebanyak 800 ml dan fermentasi menggunakan ragi (Saccharomyces cerevisiae) sebanyak 6 gram yang diperoleh secara komersil. Variasi waktu fermentasi bioetanol dari kulit singkong  yaitu 3 hari (sampel A), 5 hari (sampel B), dan 7 hari (sampel C). Proses destilasi menggunakan suhu 80  selama 2 jam. Teknik karakterisasi bioetanol terdiri atas kadar air, kadar bioetanol, nilai kalor, dan pH. Persyaratan mutu bioetanol mengacu pada SNI 7390:2012 tentang kadar bioetanol terdenaturasi untuk gasohol. Terdapat pengaruh waktu fermentasi terhadap karakteristik bioetanol berbasis kulit singkong. Seiring dengan bertambahnya waktu fermentasi maka akan terjadi peningkatan pada nilai kadar air yaitu 0,05% - 0,83%, kadar etanol yaitu 80,74% - 84,74%, nilai kalor yaitu 695,412 kkal/kg – 978,728 kkal/kg, dan pH adalah 3,5 - 4,0. Waktu fermentasi agar dihasilkan kadar bioetanol dengan karakteristik yang optimum didapat pada waktu 7 hari (sampel C) dengan hasil pengukuran kadar etanol yaitu 84,75%, karena kadar etanol lebih tinggi dari sampel lainnya dan hasil kadar etanol mendekati syarat mutu standar SNI 7390-2012

The purpose of this study is to examine and characterize students’ use of deductive reasoning when addressing mathematical problems using linear programming that is based on the Adversity Quotient. This kind of study is qualitative and descriptive. Purposive sampling was the method of sampling employed in this study. There were three different sorts of pupils in class XI IPA I SMA Negeri 5 Batanghari: Quitter, Camper, and Climber types. There were 19 total participants in the study. Each category was represented by one subject, resulting in three students who were chosen as research subjects. Questionnaires, interviews, and tests of problem-solving were the research instruments employed in this study. The processes of (1) Reducing the data, (2) Presenting the data, and (3) Concluding were used to evaluate the collected data. The research’s findings demonstrate that Quitter-type kids are capable of performing calculations based on rules or formulas to comprehend difficulties. Still, they are unable to meet the problem-solving markers when it comes to formulating logical conclusions and gathering direct evidence. Students who are camper type can compute using rules or formulas to comprehend problems, plan, and carry out plans, but they are unable to double-check. Students cannot meet the issue-solving markers when they are gathering direct facts and generating logical conclusions. Students who are climber types can satisfy deductive reasoning requirements by comprehending problems, making plans, carrying them out, and double-checking
