Abstract

The aim of this study to determine the addition effect of red dragon fruit peel powder on the physical and chemical quality characteristics of young coconut jam and get out the right concentration of making young coconut jam on sensory analysis.This study used a completely randomized design with 5 treatments and 3 replications. The research data were analyzed statistically using ANOVA and continued with the Duncan' New Multiple Range Test (DNMRT) at the 5% level. The treatment in this study was the addition of red dragon fruit peel powder with a concentration of 4% (treatment A), 12% (treatment B), 20% (treatment C), 28% (treatment D) and 36% (treatment E). The results showed that the addition of red dragon fruit peel powder had a significant effect on water content, ash content, pH, total dissolved solids, total sugar, Vitamin C, antioxidant activity and betacyanin.

Abstract

This study has aimed to determine the potential use of catechins derived from gambier as an anti-microbial raw material in the manufacture of hand washing liquid soap. The study started from the purification process of catechins from gambier and continued with the addition of gambier to the soap formula looking for hand washing. In this study, there were some difficulties in obtaining catechin extracts that could dissolve in water due to the character of catechins that did not dissolve completely in water. Therefore, the optimization of the catechin extraction process is optimized first. The catechin extraction process was carried out in two ways, namely by using a homogenizer at a speed of 15000 rpm for 30 minutes and a reflux process with hot water (temperature 70 degrees Celsius) for one hour. It was found that the concentration of catechin dissolved in water both in the homogenizer and reflux results was relatively the same, therefore for the manufacture of hand washing liquid soap, the process with the reflux technique would be recommended because of the cheaper operational costs.

Abstract

This study aimed to find the optimum conditions for extracting the carotenoid content in orange sweet potato in an applied application. The extracted carotenoids will be used as raw materials to produce rose-scented aromatic compounds (b-ionone). The extraction process was carried out on dry matter using maceration technique and using hexane as solvent. Other solvents such as methanol, ethanol, isopropanol and choloroform were also used to extract carotenoids from orange sweet potato. The use of wet samples and dry samples was also carried out in this study. The ratio of the solvent used with the material was 1:3. Based on the yield and spectrophotometric characterization, it was known that the extraction process with hexane solvent can extract carotenoid compounds from dry orange sweet potato powder if the extraction process is carried out 7 times
