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.
