<![CDATA[According to preliminary research conducted at Balai Besar Keramik, it is found out that “Batako Padalarang” products available in the market are still below the Indonesian National Standard requirement (SNI 03.2113.91). This research is conducted to obtain optimum process parameters to meet the requirements of Indonesian National Standard. The method used is Taguchi Parameter Design to fulfill the criteria for compression strength of Indonesian National Standard. From the analysis of Taguchi method, we get to know that the factors and level that affect the batako’s strength of compressive significantly are factor A (forming pressure) with level 2 (4 ton), factor B (material composition) with level 1 (1 : 3), factor C (texture of tras) with level 1 (0,3 mm), factor D (mixing time) with level 2 (10 minutes), factor E (water percentage) with level 2 (15%), and factor F (curing time) with level 3 (28 days). And from the confirmation experiment we get percentage of increase after using Taguchi method amounting to 72.75% and the decrease of loss 92.82%. Keywords : Taguchi, batako, loss fuction]]>
