Abstract

The Banana is the most widely produced fruit in Indonesia with waste of banana peel about 1/3 of the fruit. If the banana peel is not utilized in large quantities it will cause environmental problems and is a waste of resources because the waste can still be utilized. The Banana peel contains a variety of compounds such as pectin 10-21%. Based on its content, banana peels have potential as a source of pectin. Pectin can be utilized in various industries of making jelly, jam, gelling, thickener, stabilizer andemulsifier. The purpose of this study was to find the influence of ultrasonic and mass on pectin yield. This research was conducted by using ultrasonic method extraction using 0.05 N HCl solvent of 400 mL and extraction temperature of 60 oC. variation of mass in this research are 5, 10, 20, 30 and 40 grams. The highest yield obtained in ultrasonic method is 20.0008 gram with yield of 25,59%. The conventional method only can reach 18,3%.

Abstract

Clove oil is usually produced from the leaves and flowers, while the twigs cloves actually have potential to be exploited. One of the latest methods that can be used is the microwave assisted extraction. The advantages of microwaves is its ability to deliver energy directly to all material, so it can save time compared to conventional extraction methods. This research aims to study the effect of solvents on the extraction using microwaves. The solvent is water because the polar so very good at absorbing microwave. The variables studied were the weight (75-150 grams) and volume of solvent (400-500 ml) , while the microwave power of 264 W. The choice of wood clove oil yield was obtained of 3.89 % on the amount of solvent to 500 ml with weight is 150 grams.

Abstract

Rice fields in East Kalimantan is one of productive land. It looks from many piles of rice husk waste in rice milling. The rice husk waste has not been used much, so this research used the rice husk waste as raw material of furfural manufacturing. This research has three stages, there are raw material preparation, hydrolysis, and product analysis. At the preparation stage, rice husk is diminished to 100 mesh, then dried in oven. Hydrolysis process used sulfuric acid 1% as catalyst with the variation times were 10, 40, 70, 100, 130 (minutes) and temperature are 30, 50, 70, 90, 105 (°C). Then hydrolysis result was filtered and the filtrate was quantitatively analyzed by volumetric method. Highest result of time variation obtained was at 130 minutes with furfural concentration as much 8,182 mol/L, while highest result of temperature variation obtained was at 105 °C with furfural concentration as much 10,741 mol/L.

Abstract

Today, microwave can be used in various chemical processes. The advantage of microwaves is able to deliver energy directly to the material. One of microwave application is the extraction process of natural materials. Microwaves can be used to reduce extraction process time of the anthocyanin from the dragon fruit skin. This research aims to determine the solvent extracted effect to the anthocyanin extraction of dragon fruit skin using microwaves. The solvent used was 95% ethanol, 85% ethanol, 75% ethanol, 95% ethanol –citric acid, 85% ethanol -acids and 75% - citric acid ethanol to the anthocyanin extraction results of dragon fruit skin extracted using microwaves. The consumption of microwave power is 400 watt with 50 gram of dragon fruits skin. Then, anthocyanin extracts are mixe with supporting materials to be made as lipstick and proposed for topical and favorite test. The best yield can be obtained by using ethanol-citric acid solvent at 25,031%.
