PROCESSING TECHNOLOGY OF BUAS-BUAS LEAVES (PREMNA PUBESCENS BLUME) INTO LIQUID SOAP AND HAND SANITIZER TESTED ORGANOLEPTIC AND ANTI-BACTERIAL

Abstract

This study aims to produce liquid soap and hand sanitizer seen from organoleptic and antibacterial tests of buas-buas leaves (Premna pubescens Blume). This research was conducted on April 20, 2022 to May 21, 2022 at the Biology Laboratory of Medan State University. This type of research is an experimental study with a completely randomized factorial design. The number of treatments in the antibacterial test was 6 combinations of liquid soap and hand sanitizer formulas with 3 replications each. While in the organoleptic test, the number of liquid soap and hand sanitizer formulations was 4 formulas. Data analysis in the antibacterial test is descriptive quantitative, while the organoleptic test uses Analysis of Variance (ANOVA) followed by the Duncan test. The parameters observed in this study were the inhibition zone of liquid soap and buas-buas hand sanitizer extract against Eschericia and Staphyloccus aureus bacteria. And the level of panelist preference for liquid soap formulas and extracts of buas-buas hand sanitizer. From the results of the study, it was found that the hand sanitizer was able to inhibit the growth of S. aureus bacteria by an average of 15 mm and against E. bacteria by 16 mm. In liquid soap with an average total inhibition zone against S. aureus bacteria is 17 mm and against E. bacteria is 19 mm. From the results of the Anova test analysis, there are differences in the level of preference for hand sanitizer formulations on color organoleptic properties with a significant value in the sample of 0.000 <0.05 and the level of absorption of a significant value in the sample of 0.001 <0.05. Meanwhile, in the liquid soap preparation, there was no difference in the level of preference for the five organoleptic properties of the formulation
