Abstract

Hand sanitizer is an antiseptic in gel form. The gel texture in hand sanitizers is caused by the carbomer which acts as a gelling agent. Therefore, this research was done to observe the effect of carbomer on the value of pH, viscosity, and microbial activity in hand sanitizers. As for testing pH using pH meters, testing viscosity was carried out using the viscometer method, while microbial activity was carried out using the Total Plate Number, Yeast Mold Number and microbial pathogen tests. Based on the data obtained, the carbomer greatly influences the increase in the viscosity of the hand sanitizer gel, the pH value was obtained at 6.0 - 7.06, while in the microbial activity test none of the microbes grew in each medium. Therefore, it can be concluded that the hand sanitizer with code P3 is the best sample

Abstract

Talang is a village in Gunung Talang District, Solok Regency, West Sumatera. Nagari Talang, which is located ± 15 km from the city of Solok and ± 50 km from the city of Padang, is the administrative center of Gunung Talang District. The livelihood of the population, in general, is farming, and a small part as traders (entrepreneurs) and government employees. With limited employment opportunities, it is very necessary to provide counseling and training to create jobs and advance industry in the trade sector in the Talang area by utilizing housewives to be able to have their income by producing superior products, namely liquid detergent, fabric softener, and deodorizer. These three products are the main products used in washing and ironing clothes. It is hoped that by producing these products, the community can be helped in terms of the economy, and in particular it can be used as a source of income for housewive organizations in opening laundry. In addition to making these products, the community service team also provides ideas and product marketing systems that can be developed in the Talang community.

Abstract

Ramuak cracker is one of the main product of Toboh Mandailing, Balai Baru, VII Koto Sungai Sariak, Padang Pariaman, West Sumatera. One of the obstacles faced by the cracker industry players is the amount of used cooking oil produced. Used cooking oil is leftover frying oil that has been repeatedly used. If it continues to be consumed, it will be harmful to health. If discharged into the environment, it will cause environmental pollution. Therefore, the Community Partnership Program Team of the Politeknik ATI Padang provided counseling about the dangers of used cooking oil and efforts to process used cooking oil into something useful, namely producing bar soap with used cooking oil as its raw material. The step of making bar soap from used cooking oil is to slowly dissolve the NaOH solution into 500 grams of used cooking oil, then stir using a stainless steel stirrer until evenly distributed and there are no more lumps. The next step is to add dyes and fragrances and stir again to form a soap mixture. Do the printing of the soap dough in the mold by coating it with parchment paper. Let stand for 24-48 hours until the saponification process is complete. PKM activities carried out well and smoothly and in accordance with the expected results. Each participant was able to make bar soap from used cooking oil very well. This activity is expected to provide insight, knowledge and input to partners regarding the process of making bar soap from used cooking oil so that it can be used for daily needs and can even be sold as an additional source of income for the community.

Abstract

Paper is made from long fibers and short fibers whose composition greatly affects the strength of the paper, as well as filler to improve the texture of the paper surface. Reducing fiber loss and filler during paper production can save resources and reduce losses for paper mills. The most significant fiber loss and filler occur in the cleaner. For this reason an analysis of the effluent cleaner is done to find out how much fiber and filler are lost from the stock during washing. Filler determination was carried out by gravimetric method and determination of fiber was carried out by graff c staining test method. From the research that has been done to get fiber and filler which is wasted during washing around 0.1 %. Long fibers are wasted around 1.16-2.44 % and 97.56-100 % in the form of short fibers. This shows that the cleaner is still efficient in separating contaminants and fibers that are good for paper.
