Abstract

Competition in the electronic industry in Indonesia is very tight, which encourages industries to compete with each other. PT Sharp Electronics Indonesia as one of the companies that produce television, especially Light Emitting Diode (LED) TV, often has problems related to quality, which are still many defects that occur in the production process. Based on the calculation of the DPMO (defects per million opportunities) average value and the sigma average value in January 2019, it was 672.67 and 4.71 respectively. The process capability index (Cpk) of production is 1.07724. The purpose of this study is to reduce the number of defects in PT Sharp Electronics Indonesia television factories using Six Sigma through the Define, Measure, Analyze, Improve, and Control (DMAIC) stages. This quality improvement is simulated with a Monte Carlo simulation which is divided into 3 scenario success solutions (reduced number of no raster, no picture and no power defects). The Cpk value in the simulation results increases to 1.1; 1.11; and 1.12.

Abstract

Our dependency towards wood has reduced the number of forests especially in Indonesia. Hence, many people tried to use another material as a replacement of wood. One of them is composite. Department of Industrial Engineering Universitas Sebelas Maret has developed paper-based composite using newspaper waste in Praktikum Perancangan Teknik Industri (PPTI) II. Unfortunately, the quality of composite is not so good. This paper tried to understand the effect of factors to responses and discover the best combination of factors to obtain the best responses. The responses of this experiment are tensile strength, bending strength and impact value. The factors of this experiment are paper pulp, PVAc glue and water. Taguchi method is used to find the appropriate orthogonal array and Particle Swarm Optimization method to find the optimum combination of the factors. Orthogonal array used in this experiment is L9 (34).  Through analysis, all of the factors are significant to tensile and bending strength, but they are not significant to impact value. The best combination of factors is 175 grams paper pulp, 130 grams PVAc glue and 175 ml water. Optimum results obtained for tensile strength is 0.7595 N/mm2, bending strength is 4.873 N/mm2 and impact value is 0.0138 J/mm2.
