Abstract

Porang tubers (Amorphophallus muellei Blume) belong to the Amorphallus genus. Porang tubers contain relatively high levels of glucomannan. Glucomannan is widely used in many industrial fields such as the food, beverage, cosmetics and medicine industries. This research was conducted to determine the sodium metabisulfite ratio levels and maceration time in the process of making porang tuber flour so that optimal porang flour is produced. Varying concentrations of sodium metabisulfite used were 0.2%, 2% and 5% with a soaking time of 1-3 hours and extraction with 60% ethanol. The highest level of glucomannan produced was when using 5% sodium metabisulfite with a 3 hour soaking process with a value of 64.575%.

Abstract

Plastic waste is already polluting the environment both land and oceans, as plastic consumption continues to increase. Biodegradable plastics are an effort to reduce environmental pollution, biodegradation plastics are plastics made from natural materials usually biodegradable plastics made from natural starch. Cassava starch is the most widely used type of starch and is developed for the manufacture of biodegradable plastics, and sweet potatoes are tubers whose starch content is quite numerous even though it has not been widely developed into plastic material. This research aims to produce natural plastics that can replace conventional plastics and reduce environmental pollution due to plastic waste. The study was conducted with variations in the composition of starch mixtures (50:0 gr, 35:15 gr, 25:25 gr, 15:35 gr, 0:50 gr) and variations in drying temperatures (40°C, 50°C, 60°C).In this study carried out organoleptic test, thickness value test, water absorption value test and degradation test. The results of this study showed biodegradable plastics that have the best characteristics are in the variation of the composition of the mixture 50:0 gr at a drying temperature of 60°C, with a thickness value of 0.11 mm and a water absorption value of 36.5%, but the rate of degradation in this variation is very slow
