Abstract

Cooking oil is vegetable oil that has been purified and can be used as foodstuff. Consumtion of cooking oil is used as a medium for frying foodstuff, to add flavor and to form texture in bread making. Cooking oil that has been used repeatedly or commonly known as used cooking oil has a very bad impact on our body and will pollute the environment if it is not managed properly. Candles are made of paraffin, melt easily when heated, and can be used as a light source. For making candle, a chemical is added, namely stearin. The function of this stearin is to give shape fot candles because stearin will solidify once it cools. The presence of palmitic acid and stearic acid contained in stearin causes stearin to be in a solid state at room temperature. The study was conducted using 400 ml of used cooking oil which was then clarified with variations in the mass of activated carbon as much as 40, 80, and 120 grams. The clarified oil will then be analyzed for its absorbance value using a spectrophotometer uv-vis, then it will become a wax with the addition of variations in the mass of stearin as much as 50, 75, and 100 grams. The resulting candle will be tested which includes hardness, organoleptic test, flame test, and flame resistance of the candle.

Abstract

The side of the production of the Gunung Kidul Cocoa Fermentation Center, DIY, in the form of cocoa pod husk, can cause a buildup of rubbish and become a nest for fungi that cause disease. Maximizing the use of cocoa shell waste is an effort so that people can increase the use value of waste into products that have higher economic value, one of which is extracting the cellulose. Cellulose fiber has several advantages such as good mechanical properties, low density, environmentally friendly, abundant, cheap, non-toxic, easily degraded, and included in renewable natural resources. Cellulose is obtained through an extraction process with two stages, namely alkaline delignification and bleaching. Therefore, this research aims to utilize the potential of cocoa pod husk in cellulose extraction for optimum conditions for the bleaching process with NaOCl 5%, 8%, 10% and 12% through analysis of yield, water content, ash content and FTIR characterization. Based on research that has been carried out, optimum results for cellulose are obtained through bleaching NaOCl 8% which has the best level of lightness and a yield of 52%. Chesson datta characterization also shows that cellulose NaOCl 8% NaOCl has the lowest water content and ash content, namely 1.4% and 0.8% respectively. FTIR analysis shows that the optimum results have the -OH stretching functional group as a representation of cellulose at wave numbers 3206 cm-1, 3442 cm-1 and 3600 cm-1. The presence of a peak in the wave number indicates that the bleaching process has succeeded in isolating the cellulose in the cocoa pod husk.
