Abstract

The increasing of pollution, dirt, sweat and bacteria on skin surface, make the need for soap increase. One form of soap is soft soap, which made from potassium salt with fatty acids. The oil phase that can be used is cooking oil with a frequency of three times frying. The purpose of this study is to determine the effect of addition of potassium hydroxide on the quality characteristics of soft soap produced. This type of research is an experimental study with a complete randomized design study of one factor on the addition of potassium hydroxide (13 g, 15 g and 17 g). Quality characteristics tests include organoleptic, pH, foam power, moisture content, free alkali and free fatty acids. Data were analyzed theoretically and statistically using Shapiro-Wilk for data normality, and Levene Statistic for data homogeneity. Normal and homogeneous data were followed by Anova test, and normal but not homogeneous data followed by Kruskal-Wallis test. Based on the results of the characteristic test showed that formula II met the quality characteristics test of soft soap, with a pH value of 10, foam power 2,26-2,30 cm, moisture content 44%, free alkali 0,08%, and free fatty acids 1,42%. Formula I does not meet the foam power test (2,20 cm) which is 2,03-2,06 cm, while the formula III does not meet the pH test requirements (7-10) that is 11. Based on the results of the data analysis the three formulas show the value (p<0,05) means that the addition of potassium hydroxide affects the quality characteristics of soft soap.

Abstract

Pegal linu traditional medicine is one of tradisional medicine that are in great demand by the community, such as in the district of Mranggen, Demak, as much as 66,50% of the people consume pegal linu traditional medicine. One of the security aspects that need to be considered in traditional medicine is the presence of heavy metal contamination. The research aims to determine the levels of Cd heavy metals in pegal linu traditional medicine with capsule dosage forms that are based on the district of Mranggen, Demak are in accordance with the regulation of BPOM RI in 2014 regrading heavy metal contamination in traditional medicines, ≤ 0,3 mg/kg. This research use explorative experimental, including : sampling, sample preparation used wet closed destruction method with HNO3 and H2SO4 (3:1)  of the destruction solution in the Kjeldhal flask, qualitative analysis of Cd with color test and Cd quantitative analysis using Atomic Absorption Spectroscopy (AAS). The results of the quantitative analysis in this study did not show the metal content of Cd, this was due the small Cd content in the sample. Quantitative analysis shows that the Cd level in 12 sampels of pegal linu traditional medicine circulating in the distric of Mranggen, Demak exceeded the threshold of heavy metal contamination determined by BPOM RI in 2014 with the highest average levels of 18,86 mg/kg and the lower average levels of 7,38 mg/kg.
