Abstract

This study studied the best levels of bioethanol from a combination of cassava peel and pineapple peel mixtures with 6 gram yeast mass and 72 hours, 96 hours and 120 hours fermentation time, to determine the optimal fermentation time and find ethanol levels according to SNI. This research was carried out by hydrolysis or cassava peel and pineapple peel using aquades for 30 minute to break the molecule into two parts, then carried out the fermentation process using Saccharomyces Cerevisae (yeast) and the distillation process using a destilator to obtain ethanol for fermentation then tested with a Refractometer to determine whether there is an ethanol level formed from the distillation process. The best sample selected was then tested for ethanol content using the Gas Chromatography tool. The results of this study are known by using the Gas Chromatography tool to determine the ethanol content contained in the distilled sample, the highest ethanol content of each combination. So that the best ethanol yield from a combination of 100% cassava peel - 0% Pineapple Peel with a duration of 120 hours fermentation producing ethanol of 89.81% is still not included in the SNI category.

Abstract

Penelitian ini bertujuan untuk mengetahui perkembangan dan tantangan ekonomi syariah di Indonesia dilingkungan perkembangan ekonomi konvensional. Praktik ekonomi syariah mengalami pertumbuhan yang baik, namun ada juga tantangan-tantangan yang bisa menghambat pencapaian visinya. Metode penelitian yang digunakan adalah metode penlitian kepustakaan (library research) yang dimana penelitian dengan cara mempelajari menelaah, dan memeriksa bahan-bahan kepustakaan yang memiliki relevansi atau hubungan hukum terhadap pokok permasalahan. Temuan pada artikel ini menunjukkan bahwa banyak nya penduduk muslim berpengaruh positif terhadap perkembangan ekonomi syariah di Indonesia, namun juga terdapat tantangan dalam perkembangan ekonomi syariah di Indonesia. Rendahnya dukungan keungan syariah terhadap industri halal hal ini menjadi penyebab tantangan yang ada.
