Abstract:
Rising plastic demand and high raw material costs highlight waste reduction as vital for cost efficiency and competitiveness. This research aims to study the application of lean principles to enhance production efficiency in the plastics industry. The population consists of 100 samples, including production managers, supervisors, and staff, with questionnaires serving as the research tool. Data analysis employed statistical measures such as percentage, mean, standard deviation, mean difference analysis, and one-way ANOVA. The research reveal that overall importance level of lean principles to enhance production efficiency in the plastics industry is high (x̄=4.11) when categorized by specific aspect, it was found that the importance of eliminating process irregularities (MURA) is high (x̄=4.14) The most critical item within this aspect is effective team building emphasizing strong collaboration and communication to identify and address irregularities (x̄=4.36) In terms of eliminating system overburden (MURI), the importance level is similarly high (x̄=4.11) with workload balancing ensuring equitable task distribution between employees and machinery to reduce overburden being the highest rated item (x̄=4.31). For waste elimination in processes (MUDA) the importance level remains high (x̄=4.08) with planned maintenance to ensure machinery is consistently ready for production, being the highest-rated item (x̄=4.29). The comparison of mean differences across variables such as registration type, business operational duration, and business size indicates statistically significant differences at the 0.05 level
