Abstract

The choice of impeller type is an important factor in maximizing the performance of a stirred tank reactor in saponification process. This study aims to determine the type of impeller that can produce the highest reaction rate by taking into account changes in alkali concentration in saponification reactions so as to obtain a shorter residence time. The saponification process was carried out by reacting 30% oil with alkali (KOH) at operating conditions 70C, stirring speed of 400 rpm for 45 minutes using 4 types of impellers namely paddle-2 blades, pitch blade turbine 45°-2 blades, paddle-4 blades, pitch blade turbine 45°-4 blades. Testing of alkali concentration was carried out every 5 minutes until the reaction was complete. Alkali concentration was obtained at the end of the reaction using a paddle-2 blades impeller of 0.182 M with a conversion of 97.35%, a pitch blade turbine 45°-2 blades of 0.142 M with a conversion of 97.93%, paddle-2 blades of 0.106 M with conversion of 98.46%, pitch blade turbine 45°-4 blades of 0.100 M with conversion of 98.54%.

Abstract

Community Service Activities for the Purun Weaving Group aim to enhance the quality of products and marketing for the "Nasti Purun" Purun Weaving Group in the Cinta Air Village, Perbaungan District, Serdang Bedagai Regency, as well as support the government's enterprise development program. Several production technologies within the "Nasti Purun" Purun Weaving Group in Serdang Bedagai are currently conducted manually, particularly the process of making Purun rope bags. The spinning of Purun rope still involves the use of hands and feet, causing discomfort, fatigue, and even injury to the workers' hands and feet. The "Nasti Purun" Purun Weaving Group in Serdang Bedagai is in dire need of a Purun rope spinning machine. The specific objective of this activity is the acquisition of a Purun rope spinning machine and providing appropriate marketing methods along with basic accounting. The implementation method is carried out comprehensively, beginning with the application of Purun rope spinning technology and proper business management development, expanding the market area using online marketing (digital marketing) as an effort towards achieving one of the SDGs objectives, Decent Work and Economic Growth. This aims to enhance inclusive and sustainable economic growth, as well as decent work for all. These activities can have a positive impact not only on the target community but also on the university.
