Abstract

In this study, a modified polyethylene glycol modified cellulose acetate membrane was made. Cellulose acetate was synthesized from cocoa husk waste (Theobroma cacao L) with several steps, namely isolation of alpha cellulose from cocoa husk waste, synthesis of cellulose acetate from alpha cellulose, preparation of 10% cellulose acetate membrane with the addition of polyethylene glycol 0, 5, 10, 15, 20 & 25% . From the results of the research, it was found that the FT-IR analysis of -cellulose from cocoa shells showed an absorption peak at wave numbers between 3400 – 3500 cm-1 which indicated the presence of O-H stretch groups. At wave numbers 2800-2900 cm-1 indicates C-H stretching, then it can be seen at wave numbers 1160 cm-1 indicates C-O-C stretching, and at 1035-1060 cm-1 indicates C-O stretching. In the fingerprint area, we found absorption peaks at wave numbers around 1300 cm-1 which indicated the presence of C-H bending and around 1400 cm-1 indicating the presence of CH2 bending. The cellulose acetate obtained is white and smooth compared to alpha cellulose. At the membrane preparation stage, the results of the insoluble cellulose acetate & PEG using acetone as a solvent. So it is necessary to do a solubility test and find a suitable solvent to form polyethylene glycol modified cellulose acetate membrane for Pb metal ion filtration.

Abstract

Curcuma can be used to maintain and improve body health as well as treat disease. Instant powdered curcuma drink is one of the curcuma plant's processed products.People in the Lubuk Minturun Koto Tangah District, Padang City have natural and human resources that can be utilized through training programs for creating instant powdered curcuma. This exercise drew a total of 25 women, including housewives and teenagers. There are three steps to this community service activity: lectures, demonstrations, and practice. Because the production method is simple and the tools and materials required are readily available, more than 90% of the participants in this activity were able to comprehend the process of making instant powdered curcuma. It is intended that by participating in this activity, the community would be able to increase entrepreneurial prospects and so boost the economy.
