Abstract

The palm oil industry plays a vital role in the national economy through palm oil mills (POMs) that process fresh fruit bunches into crude palm oil and packaged products. The Consumer Packaging (CPC) department ensures product quality, yet its tasks requiring high accuracy, speed, and consistency may cause mental workload. This study assesses and analyzes the mental workload of Consumer Packaging (CPC) operators in a palm oil mill using the NASA-TLX method, involving eight respondents from the forklift, Samarpan machine, packing, and stuffing units. The results indicate an average NASA-TLX score of 82% (very high category), with effort identified as the dominant dimension (26%). Simulation of additional workers reduced workload to 59.6%. These findings highlight the importance of task redistribution, workplace improvements, and temporary contract workers to maintain productivity and operational sustainability.

Abstract

This study aims to determine the effect of interactive multimedia based on Canva on the understanding of IPAS concepts among fifth-grade students at State Elementary School Fourteen in Bengkulu City. This study uses a quantitative approach with an experimental method using a matching only pre-test–post-test design. The research sample consists of fifth-grade students at State Elementary School Forty-Five in Bengkulu City as the experimental group and fifth-grade students at State Elementary School Forty-Two (SDN Forty-Two) in Bengkulu City as the control group, selected through cluster random sampling. The instrument used was a 5-question essay test administered through pretest and posttest. The data analysis techniques used were descriptive statistical tests, prerequisite tests, and inferential tests. The average posttest score for the control group was 56.67, while the average posttest score for the experimental group was 77.50. The results of the independent sample t-test on the posttest showed that the calculated t-value of 3.539 was greater than the table t-value of 2.023 (df = 41, α = 0.05) and the Sig. (2-tailed) value of 0.001 < 0.05. This indicates a significant difference in the understanding of IPAS concepts between the two groups. The difference in scores is attributed to the different treatments applied to the two groups. Based on this, it can be concluded that interactive multimedia based on Canva has a positive effect on the understanding of IPAS concepts among fifth-grade students at State Elementary School Cluster Fourteen in Bengkulu City
