Abstract

Oil palm empty bunches (TKKS) are solid waste from palm oil processing which is quite large and until now its utilization is still not optimal. Therefore, it is necessary to innovate the processing technology of oil palm empty bunches in order to produce products that have more usefulness and high economic value as well. One of the processed products from the solid waste of oil palm empty bunches is composite. By utilizing solid waste of oil palm empty bunches (EFB) to be used as a base material for making (filler) and BTQN 157 EX resin as a matrix, catalysts as hardeners and glass fibers (fiberglass) as reinforcement are expected to produce composite boards that have proven quality by testing. impact standard ASTM E23. This research was conducted at the STIPAP TPHP Laboratory and the Laboratory of Basic Phenomena of Mechanical Engineering, the Medan Institute of Technology (ITM). The research period was 2 months, namely July - August 2019. This research used handmade methods and charphy impact testing with a composition of 29% OPEFB fiber, 157 ex 70% BTQN resin, 1% catalyst and glass fiber. The results showed that the average absorption energy of the 8 samples was 0.833 Joules and the average impact price was 0.0108 joules / mm2.

Abstract

Palm Fatty Acid Distillate (PFAD) is a by-product of the palm oil refining process which contains 80% of free fatty acids (ALB). Overall the palm oil manufacturing process will produce 73% olein, 21% stearin, 5-6% PFAD and 0.5% trench CPO. CPO can be used to produce solid palm oil (RBD stearin) and liquid palm oil. PFAD is a by-product of the Fractionation process at the Downstream Industry plant, which can add value to the industry if it is developed, for example, as a raw material for pomade. This study aimed to determine the quality of pomade hair oil based on PFAD and Glycerine using the organoleptic method. The stages of this research are; (1). Sampling (2). Deodorization (3). Pomade Making (4). Organoleptic analysis (5). Test data using LSR (BNT). The color BNT test analysis results with the notation of 0.01 and 0.04 seem to give a significant difference in the aroma analysis test P1M1 P2M2 with P3M3 P4M4 P5M5 it looks very significant and the results of the texture analysis test also show a very significant difference.

Abstract

This Community Service Program aims to implement an aquaponics system with DFT hydroponics in water spinach cultivation in Dolok Sagala Village, Dolok Masihul Subdistrict, Serdang Bedagai Regency. The aquaponics system combines fish farming with plant cultivation, where fish wastewater is used as a plant nutrient source. In contrast, the DFT hydroponics system allows efficient nutrient circulation. The application of this technology aims to increase agricultural productivity in limited land areas, provide sustainable farming solutions, and enhance local food security. The results of this activity show that the aquaponics and DFT hydroponic systems can significantly improve the growth of water spinach with minimal use of land and resources. Community participation in this activity also increased, reinforcing awareness of the importance of modern agricultural technology.

Abstract

Soap is one of the cleaning materials whose use is evenly distributed in every mosque, house and other public facilities. The relatively simple process of making soap should be an opportunity for the community to individually make soap, so as to increase community income and produce environmentally friendly soap. This community service aims to train the Al-Ikhwan Islamic Youth Association (IKRIA) Martubung Village, Medan Labuhan Subdistrict, Medan City. Homemade soap production has promising business activity prospects for IKRIA Mosque Teenagers. Home-made soap products can be an alternative to commercial solid soap for bathing or washing. Furthermore, soap making can be developed into natural soaps that are healthy and environmentally friendly. The problem of the Mosque Youth is that there is no basic knowledge related to making solid soap based on palm oil derivatives, so it is necessary to conduct practical training in making solid soap on a home scale. The training methods carried out were lectures, discussions and continued with solid soap production practices. This training activity is expected to increase the enthusiasm and knowledge of the IKRIA Mosque Youth to try to produce solid soap at home, so that it can increase the income of the Mosque Youth individually and collectively.

Abstract

Used cooking oil is a household waste that can pollute the environment if disposed of improperly. In Mabar Village, Bangun Purba District, public awareness of waste oil management remains low. This community service program aims to provide environmental education for elementary school students by introducing the utilization of used cooking oil to produce candles. The program involved 21 students from grades 4–5. The methods included socialization on the dangers of used oil, hands-on candle-making practice, and evaluation using pre- and post-tests. The results show a significant improvement in students’ understanding, rising from 20% on the pre-test to 85% on the post-test. Furthermore, all participants successfully produced candles independently. This program effectively enhances children’s knowledge and environmental awareness.

Abstract

This study aims to determine the feasibility of using 500-ton and 1000-ton Crude Palm Oil (CPO) storage tanks in a palm oil mill. The evaluation is based on the roundshell thickness, operating temperature, and hydrostatic pressure acting on the tanks. A descriptive quantitative method was applied using primary and secondary data from PMKS Simpang Gambir. The results showed that for the 500-ton tank, the calculated roundshell thickness is 8.6 mm, the actual is 8.87 mm, and the design is 9 mm, with a hydrostatic pressure of 5.73 Pa. For the 1000-ton tank, the calculated thickness is 13.1 mm, the actual thickness is 13.8 mm, and the design thickness is 14 mm, with a hydrostatic pressure of 11.46 Pa. The corrosion rates are 0.00072 mm/month and 0.0011 mm/month, respectively. Based on the analysis, the 500-ton tank is feasible for continued use for approximately 31 years, and the 1000-ton tank for 53 years, assuming constant corrosion rates.
