This research was conducted to determine the effect of the type of solvent and particle size on the extraction of cocoa pods using the Microwave Assisted Extraction (MAE) method on the characteristics of the extract as a source of antioxidants and to determine the type of solvent and particle size in the extraction of cocoa pods using Microwave Assisted Extraction (MAE) precise in obtaining the highest antioxidant capacity extract. The experimental design used in this study was a factorial randomized block design which was grouped into 2 groups based on the implementation time and consisted of two factors. The first factor is the type of solvent which consists of 3 levels, namely methanol, ethanol and acetone. The second factor is particle size which consists of 3 levels, namely 40 mesh, 60 mesh and 80 mesh. The data were analyzed by analysis of variance and continued with Tukey test. The results showed that the type of solvent and particle size had a very significant effect on the yield, total phenolic, total flavonoid and antioxidant capacity. The interaction between treatments had a very significant effect on total flavonoids and antioxidant capacity, and had a significant effect on total phenolics, but had no significant effect on the yield of cocoa pod peel powder extract. The best treatment to produce cocoa pod peel extract on extraction using MAE was ethanol solvent and particle size 80 mesh with yield characteristics of 12.23±0.61% total phenolic 148.84±0.10 mg GAE/g extract, total flavonoids of 94.16±0.23 mgQE/g extract, and antioxidant capacity of 133.30±0.49 mg GAEAC/g extract.

This study aims (1) to determine the effect of ratio between material and water solvent, and distillation time on the characteristics of acetic acid produced from the pulp liquid waste by product of fermented cocoa beans, and (2) to determine the ratio between material and water solvent, and distillation time which produces the most potential distillate that can be used as a basic ingredient to produce the best acetic acid. The experiments in this study were using a randomized block factorial design (RBFD) with 2 factors. The first factor was the ratio of material and water solvent (A) which consists of three levels, i.e. 1:1, 1:2, 1:3, and the second factor was the distillation time (B) which consists of three levels, i.e. 10, 20, 30 minutes. Research was carried out 2 times, therefore it was found 9 treatment combinations that were grouped into 18 experimental units. The treatment of ratio between material and water solvent affects the percentage yield of distillate, pH, total acid and acetic acid. The treatment of distillation time affects the percentage yield of distillate, pH, total acid and acetic acid. The interaction treatment A and B significantly affects the percentage yield of distillate, but it does not affect pH, total acid and acetic acid. The ratio between material and water solvent (1:1) with distillation time of 30 minutes is able to produce the most potential distillate that can be used as a basic ingredient to produce the highest percentage of distillate yield of 69.50%, pH 2.95, total acid 0.04 meq NaOH/g, and 0.22% acetic acid.

The purpose of this study was to determine the effect of heating temperature and carbopol concentration on the characteristics of hand washing liquid soap, as well as to determine the heating temperature and the best concentration of carbopol to produce hand washing liquid soap. This study used a factorial randomized block design with a 2-factor trial. The first factor is the heating temperature which consists of 3 levels are : 70?C, 80?C, 90?C. The second factor is the concentration of carbopol which consists of 3 levels are: 1%, 2%, 3%. The results showed that the heating temperature, carbopol concentration and interaction between the two treatments had a very significant effect on viscosity. Comparison of heating temperature has a very significant effect, but the concentration of carbopol and interaction between treatments has no significant effect on specific gravity and stability of foam. The ratio of carbopol concentration has a very significant effect, heating temperature has a significant effect but the interaction between the two treatments has no significant effect on the foam height. The treatment of heating temperature, carbopol concentration and interaction between treatments had no significant effect on water holding capacity, pH, free alkali and overall reception. The best treatment was obtained from the treatment of 80?C heating temperature with 1% carbopol concentration. Keywords: Heating temperature, carbopol concentration, saponification, liquid soap.
