Abstract

Porang (Amorphophallus Muelleri Blume) is a type of tuber that contains various nutrients, especially glucomannan. Besides as being a source of food, the high content of glucomannan can also be used as an alternative for making edible films, because it contains mannan polymers which have the ability to form fine and crystallized fibers. The purpose of this research is to determine the potential of glucomannan in porang tuber flour as a basis for making edible films. Glucomannan used with various variations (3, 6 and 9 grams). The first stages used were testing porang tuber flour and then made edible film base by carrying out various chemical analyzes based on the Japanesse Industrial Standard method. The results showed that the acquisition of water, ash and protein sequentially was 11.782%, 1.821%, 6.275% which conform to the SNI 7939;2013 standards. The 3 gram variation and 0.087 mm thickness of Glucomann showed the best water resistance value of 20.34%. The biodegradability test showed that the 6 grams variation of glucomannan had the best degradation ability, that is 100% for 12 days.

Abstract

Food packaging is the process of protecting a food product to maintain durability and quality consistency. Edible film made from porang tubers is a sustainable and innovative solution to reduce plastic waste and improve food preservation. Porang tuber (Amorphopallus muelleri blume) is a valuable plant as its high glucomannan content can be processed into porang flour. The drying process is one of the important steps in the preparation of porang tuber flour. One of the polysaccharides used in edible films is starch from glucomannan derived from Porang tubers. Glucomannan is an alternative material developed because of the high polysaccharide content in porang tubers, namely mannan, which has the ability to form a good film layer, good biocompatibility, biodegradable and has the ability to form a gel. This study was conducted with the aim to determine the effect of drying temperature on the results of edible films obtained, in terms of swelling and tensile strength values using porang tuber starch. The main stages of this research are the preparation of glycerol-plastized porang tuber flour solution and then the stage of making porang tuber flour edible film. In the manufacture of edible film, the drying process is carried out with temperature variations of 40, 50 and 600C. The highest swelling and tensile strength values were obtained in porang flour edible film at 50 0C, where the swelling and tensile strength values were 61.1% and 0.75 MPa.

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

Abstract

Environmental pollution due to textile industry waste, especially synthetic dye waste, has become increasingly widespread and has become a serious concern in recent decades. Dyes such as Metanil Yellow are often found polluting waters, causing adverse impacts on ecosystems and human health due to their toxic and difficult-to-decompose nature. This study aims to identify the characteristics of hydrogels made from kepok banana peels in absorbing and degrading Metanil Yellow dye. The research methods used include organoleptic tests to determine the physical characteristics of the hydrogel, water absorption tests to measure the capacity of the hydrogel to absorb liquids, and dye degradation tests using a UV-Vis Spectrophotometer to determine the effectiveness of the hydrogel in absorbing Metanil Yellow dye. The results showed that the hydrogel had a smooth texture, had the highest water absorption capacity of 81.30% hydrogel with the addition of 0.6 grams of Sodium Tripolyphosphate, and the highest degradation of Metanil Yellow dye, which was 46.95% at a concentration of 10 ppm. %. Hydrogels made from kepok banana peels have the potential to be used as absorbers of Metanil Yellow dye.
