Abstract

The manufacturing industries in Indonesia have been improving rapidly thus make the industries to be in ore competitive environment. This research is conducted to design a refinement or quality improvement for paving products in PT. Malang Indah. The quality improvement is done with Taguchi method experimental design in order to get optimal mixture combination. As for the orthogonal array notation used is L9 (34) with cement (A), fly ash (B), and sand (C) as the controlling factors. The data processing will be done with ANOVA calculation towards the average value and SNR with larger the better as classification. The ANOVA calculation is done in order to find out the significantly influential factors in product durability. The test done to find out the product durability is a pressure test which is done with compression machine. According to the result of data processing, the ratio of optimal mixture composition cement: fly ash: sand is 1:3:6 (A1, B2, and C3). A confirmation experiment will be done to the optimal composition during the control stage to find out the validity. According to the calculation in confirmation experiment, the result for pressure durability is 450,117 kg/cm2 which indicate the quality of paving category a based on SNI 03-0691-1996. Keywords: Quality Improvement, Taguchi Method
