Abstract

Nagari Paninjauan, located on the slopes of Mount Marapi in West Sumatra, faces significant agricultural challenges, particularly due to rising chemical fertilizer costs, which affect productivity and farmers' welfare. High dependency on chemical fertilizers has also harmed soil health and the environment. To address this, a community service team from UNP held a training on producing organic liquid fertilizer (POC) tailored for various plant growth stages, such as soil enhancement, vegetative, and generative phases, as well as making organic growth regulators, fungicides, and insecticides. The training included material presentation, hands-on practice, and application in farming fields. Results showed participants’ understanding of POC production rose from 43.8% to 86.7%, and awareness of agricultural waste’s economic value also improved. Although the training effectively increased farmers' skills in independently producing POC, further strategies are needed to enhance understanding of technical materials for greater environmental and economic impact.

Abstract

Cosmetics in cream form are more suitable. Stearic acid and triethanolamine are used as emulsifiers in making creams. The purpose of this study was to see the variation of stearic acid with triethanolamine that produces a stable cream against the physical properties of the cream preparation. The cream made was a cream with an oil-in-water (w/o) type with variations of stearic acid 5, 10, 15, 20%, and triethanolamine 2, 2.5, 3, 3.5, 4%. The heating temperature used was 400C. The cream preparation formed was evaluated through physical property testing including pH testing and Homogeneity testing and organoleptic testing. The results showed that the higher the concentration of stearic acid used, the pH of the cream decreased, but was still within the requirements of a good cream for the skin, as well as homogeneity, the higher the concentration of stearic acid, the more homogeneous the cream produced. Panelist organoleptic testing liked the color, odor and homogeneity of the 20% stearic acid variation, which was preferred by panelists. Based on the results obtained, it can be concluded that the concentration of the cream preparation with variations of stearic acid: triethanolamine 20%: 3.5% is the best preparation based on testing of physical and organoleptic properties.
