Abstract

Quality control needs to be done to face industrial competition. PT. Sukuntex is a textile industry that produces fabrics, one of which is polyester with 58% production from the total fabric production. PT. Sukuntex has a make to order fabric production system, the company carries out quality control by inspecting every fabric produced in the quality control division. In this study, an analysis of polyester fabric quality control using the six sigma method with the DMAI (Define-Measure-Analyze-Improve) steps to determine the DPMO value, the company's sigma level, the causes of defects, and improvements. The results of this study found 3 dominant defects based on the Pareto diagram, namely thin thickness, sparse, and dirty oil. In calculating the DPMO value, the result is 49,825.15 meters with the sigma value obtained is 3.15. The sigma value can increase with quality improvement. Therefore, the causes of defects were analyzed using a fishbone diagram which resulted in human, machine, method, and environmental factors. FMEA-AHP method for improvement priorities, where FMEA analyzes the ranking of the causes of defects, then prioritizes improvement based on weights with AHP. Improvement plan using the 5W+1H method at the improve stage.

Abstract

Low student interest in science learning remains a common problem in elementary schools, characterized by a lack of student engagement and enthusiasm during the learning process. This study aims to analyze the implementation and the effect of using the ASLINE-3 interactive media on increasing students’ interest in learning. This study employed a quantitative approach with a one-group pretest-posttest pre-experimental design. The research subjects were 26 fifth-grade students from Class V-A at SDN Kalirungkut I/264 in Surabaya. Data collection techniques included a questionnaire to measure students’ interest in learning and observation to assess the implementation of the learning process. The data were analyzed using descriptive analysis and N-Gain. The results of the study indicate that the implementation of learning using the ASLINE-3 media was in the “very good” category, with a percentage of 100%. Students’ learning interest increased, as indicated by a rise in the average score from 78.08 to 92.69. The N-Gain analysis result of 0.73 indicates a moderate category (fairly effective). Thus, the use of the ASLINE-3 interactive media has proven effective in increasing students’ learning interest in IPAS instruction and can serve as an alternative for technology-based instructional innovation in elementary schools.
