Abstract

The purpose of this study is to examine the effect of reaction time and temperature toward the formed of soap product. This study begins by drying the skin of cotton and burning to gain the ash of cotton fruit skin. The combustion is done by using muffle furnace at 500 oC for 3 hours. Then, extraction is done on ash by using aquadest with a ration 1:3 to obtain alkali. This alkali will be used with cooking oil from palm in saponification process with fixed volume variable oil of 30 ml, velocity of stirring is 250 rpm, and oil volume : alkali volume 1:2 (ml). Whereas for the free variable are reaction temperature at 60­ oC, 70 oC, 80 oC, stirring time at 60 minutes, 90 minutes, 120 minutes. The observed responses are density, acidity (pH), saponification number and free alkali. The best results were obtained at 80 °C and stirring time of 120 minutes with a density of 1.34 gr / ml, pH 9.1, saponification number of 200.349 and a 0.07% free alkali content.

Abstract

The purpose of this study was to determine the best of combustion time and temperature of ash production from kapok fruit peel ( Ceiba Petandra ) to get the most potassium. The experiment was begun to dry kapok fruit peel for 24 hours at oven with temperature 110 oC and combustion to obtaine the ash from kapok fruit peel. The combustion was done by muffle furnace which time variables were from 3 hours, 4 hours, 5 hours, and 6 hours and burning temperature variables were from, 500 oC, 550 oC,600 oC, 650oC. The potassium that contained in ash have been extracted by distilled water with volume 30 ml for 24 hours. Observed responses were normality, pH, ash content, and potassium oxide content (% K2O). The best result of ash was in 3 hours with temperature 500 oC. The ash was analyzed by using AAS Atomic Absorption Spectroscopy, and 35.91 % of potassium oxide (K2O) content was obtained as maximum result.
