Abstract

Oil palm trunks are waste products from plant rejuvenation that can be another source of starch. This study aims to examine how the temperature of acetic acid hydrolysis affects the properties of starch from oil palm trunks. The method used was a nonfactorial Completely Randomized Design (CRD) with three variations of hydrolysis temperatures, namely 40°C, 45°C, and 50°C, each repeated three times. The parameters observed included moisture content, ash content, amylose content, amylopectin content, and functional groups with the help of FTIR. Data were analyzed using ANOVA at the 5% level. The results of this study indicate that the hydrolysis temperature affects the properties of starch. A temperature of 40°C produces the lowest moisture content of 10.16%, while a temperature of 45°C produces the highest amylose content of 13.43% and the lowest amylopectin content of 86.56%. Treatment at 50°C shows a decrease in starch quality due to structural damage during the hydrolysis process. The FTIR analysis results showed the presence of typical starch functional groups such as O–H, C–H, and C–O–C in all treatments. The results of the study showed that a hydrolysis temperature of 45°C was the best treatment for obtaining oil palm stem starch with the best properties.

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.

Abstract

This study aims to analyze the operational effectiveness of the Ripple Mill machine using a TPM maintenance strategy approach by measuring OEE. The method used is descriptive quantitative, with primary data from observations and interviews, and secondary data from factory operational documentation. The evaluation was based on three leading OEE indicators: availability, performance, and quality. It was complemented by an analysis of the six significant losses to identify sources of lost production time. The results show that the average OEE value from January to March 2025 reached 96.53%, exceeding the international standard of ≥85%. The most significant losses came from equipment breakdowns (69.75%), followed by minor breakdowns and idling (18.48%). Preventive maintenance programs, operator training, and spare parts availability are recommended. These results demonstrate the effectiveness of the TPM approach in continuously improving machine performance.
