Abstract

Used refined cooking oil can be used to make soap. An important factor in the manufacture of soap is the saponification reaction between bases (KOH) and fatty acids. The addition of citrus essential oil to the soap preparation can increase consumer acceptance. This study aims to determine the effect of KOH concentration on the characteristics of liquid soap and to determine the proper concentration of KOH to produce good quality of liquid soap. This research uses a factorial completely randomized design with one factor that is KOH concentration, consisting of three levels ie 25%, 30% and 35%. Characteristics of liquid soap observed were viscosity, foam height, pH, and free alkali content. The results showed that the concentration of KOH effect on the characteristics of  liquid  soap  produced. If  KOH concentration increases,  viscosity,  pH and alkali-free  alkali content of the liquid soap increased. The best KOH concentration is 25%.

Abstract

Vinegar could be produced from any fruit juice. Coconut water as raw material was used by increasing sugar concentration. Vinegar is one of the alternatives in the use of coconut water waste. This is supported by the needs of the growing vinegar. Vinegar  manufacture involves two stages of fermentation (anaerobic and aerobic). Aerobic fermentation by adding yeast and sugar yield of 12% alcohol (the alcohol optimal), where as aerobic fermentation produces vinegar 4% -12.5% (SNI). The purpose of this study were to determine the optimal percentage of the addition of yeast and sugar to produce alcohol 12%, and to compare the quality of coco vinegar with SNI 01-3711-1995 vinegar. This study used factorial completely randomized design , the adding sugar and  yeast as treatment, 3 level of adding sugar and  yeast with 3 observations. Results of variance analysis  showed that the treatment was very real effect on levels of alcohol and alcohol pH. The Duncans Multiple Range Test (DMRT) showed that the highest quality levels of alcohol present in addition of 16% sugar and   6% of yeast. while the pH of alcohol contained in the addition of yeast 4.5% and sugar 10%
