Abstract

This study aims to evaluate and implement a Six Sigma strategy to reduce ceramic product defects at PT Sun Power Ceramics and to improve production efficiency significantly. The research employs a quantitative approach based on the Six Sigma DMAI cycle (Define, Measure, Analyze, Improve). Data were collected from 14 production observations covering four primary defect types: chips (gumpil), cracks (retak), holes (lubang), and body contaminants (kotoran body). The analysis includes calculations of defect proportions (p), a p-control chart, DPMO (Defects Per Million Opportunities), sigma level, and process capability, followed by root-cause analysis using cause-and-effect (fishbone) diagrams and Failure Mode and Effect Analysis (FMEA). The results show a total of 6,402 defects, with chips being the most dominant type (28.2%). The overall process operated at an average sigma level of 3.01, an average DPMO of 66,272, and a process capability (Cp) of 1.003, indicating that the process is only moderately capable. FMEA identified cracks caused by excessive material moisture content as the highest priority, with an RPN of 504. Based on these findings, Six Sigma-based improvements such as standardizing moisture content, controlling the kiln, calibrating machines, training operators, and conducting routine inspections are recommended to reduce defects and move the process toward the zero-defect target, thereby improving product quality and operational efficiency at PT Sun Power Ceramics.

Abstract

The increasing volume of plastic waste in coastal areas poses a significant environmental challenge that requires collaborative solutions. This Community Service Program aims to empower the coastal community of Mlaten Village, Pasuruan Regency, by transforming plastic bottles into functional and economically valuable chairs. The approach employed ils Partilcilpatory Rural Apprailsal (PRA), whilch emphasilzes actilve communilty ilnvolvement iln all stages—from problem ildentilfilcatilon to solutilon ilmplementatilon. Through trailnilng and mentorilng actilviltiles, the communilty not only gailned creatilve recyclilng skillls but also enhanced theilr awareness of ilndependent waste management. The results ilndilcate ilmproved communilty capacilty iln utillilzilng plastilc waste and the emergence of local creatilve busilness ilniltilatilves. The expected ilmpact ilncludes a cleaner envilronment, strengthened local economy, and the sustailnabillilty of communilty-based programs.
