Abstract

Liquid dish soap is one of the staples needed to clean kitchen equipment. The education for making liquid dish soap uses various surfactants, including: Sodium Lauryl Sulfate, Alkyl Benzene Sulfonate, Cocamido Propyl Betaine. Soap making only mixes the ingredients in a predetermined sequence. The purpose of this education for making liquid dishwashing soap is to provide knowledge and training and reduce public spending on purchasing soap, as well as opportunities to create new business opportunities. Participants are given the opportunity to make their own preparations accompanied by facilitators from trained lecturers and students. There were 30 active participants and were asked to fill in the Pre Test and at the end of the Post Test event, with the results of the analysis showing an increase in good knowledge regarding the uses of various kinds of water and the functions of the several compositions of ingredients used for making liquid soap. Participants were also asked to fill out a questionnaire for activity evaluation. This questionnaire has been tested for validity by comparing the value of r table with the value of rcalculated at significance (0.05), and declared valid because all questions are greater than r table, namely > 0.2673. The reliability test also shows a reliable questionnaire which shows that the value of Cronbach's Alpha is greater than the constant value of 0.823, which is greater than the constant value of 0.600. Evaluation of the activity was based on the total percentage of answers stating "Very good (60.9%)" and "Good (35.0%)", so that it can be seen that participant satisfaction was very high, namely 95.9%. The input that was proposed for the next activity was Making Eco Enzyme, but some participants also wanted to make laundry soap.
