Abstract

Sampah rumah tangga masih dianggap sebagai limbah tidak bermanfaat,. Jika tidak ditangani dengan baik, maka akan menjadi penyumbang terbesar sampah yang dibuang ke TPA yang berdampat buruk pada lingkungan. Pembuatan eco – enzyme dari sampah rumah tangga merupakan salah satu alternative pengelolaan sampah yang bisa dilakukan karena mudah dan murah. Manfaat eco – enzyme sebagai cairan multiguna yang bernilai ekonomis sehingga dapat dipasarkan. Pelatihan pembuatan eco enzyme ini bertujuan agar masyarakat dapat mengolah sampah organik yang dihasilkan dari rumah tangga secara mandiri dengan mudah dan murah menjadi sesuatu yang bernilai ekonomis dan dapat dimanfaatkan kembali, sehingga pengelolaan sampah secara mandiri dapat dilakukan secara berkelanjutan dan merubah perilaku masyarakat terhadap penggunaan bahan – bahan kimia sintetis sebagai bahan pembersih di rumah tangga untuk beralih ke bahan alami yang lebih ramah lingkungan.

Abstract

In view of information on rambutan creation which is expanding, the misuse of rambutan strips and seeds is likewise expanding. Remembering that rambutan strips and seeds contain a few mixtures that can be utilized as elective unrefined components in the production of bioethanol. This study aims to determine the effect of variations in the addition of yeast on the yield and content of bioethanol, and also to determine the maximum mass of the addition of yeast to acquire the biggest yield and ethanol content. This research went through 5 stages, first stage is the readiness of the skin and seeds of rambutan, second stage is α-cellulose detachment, third step is hydrolysis with 1% HCl to create glucose which will be analyzed using Benedict's reagent and the Luff-Schoorl method. Qualitative analysis showed positive results and glucose levels obtained were 22.39% with a glucose yield of 1.50%. The fourth stage is glucose fermentation by using five days with variations in yeast weight of 5, 6 and 7 grams. The fifth step is to separate the resulting bioethanol by distillation and determine alcohol content using an alcohol refractometer. Yield bioethanol obtained by varying the weight of yeast 5, 6, and 7 grams respectively was 1.05%, 1.18%, and 1.67% with the levels of bioethanol obtained 1.95%, 2.15%, and 3.00%. The highest yield and content of bioethanol were obtained by adding 7 grams of yeast. The yield obtained on this bioethanol is 1.67% and the bioethanol content is 3.00%. Keywords: bioethanol, cellulose, fermentation, hydrolysis, rambutan peels.
