Abstract

Body Shop consists of the assembly production process area of sub items or components combined with car cabin manufactured mostly using the base material of metal plate by using electric welding resistance method or Spot Welding. Spot Welding can be done by using an electrode with another name CAP TIP (Electrode Tips), made of copper alloy run by a large electric current, in a relatively short time. The grafting material process generates spatter. The spatter spots are discovered on the cabin plane. This study aims to analyze the effect of CAP TIP (electrode tips) on the remaining spatter spot found on car cabin using ANOVA method. The survey data were obtained from 3 types of CAP TIP (PG 1712, PG 1431, PG 1777-50) of 10 types of CAP TIP used in the body shop area along with the amount of residual spatter produced. The results revealed variant similarity of the three types compared from the Levene statistic value of 1,563, with the average number of residual spatter most produced by CAP TIP PG 1712 as 47.17, while the F value of 0.914 with the significance of 0.443 indicating no significant CAP TIP type difference against the rest of the spatter, thus H0 is rejected. This proves that there is no effect of CAP TIP (electrode tips) on the remaining spatter spots.Keywords: Electrode tips, Welding spot, Spatter spot, ANOVA

Abstract

CV. Faresti Prima which is a company engaged in machining, automatic part, dies, and jigs. Union Pipe Unit is part of the research because it has problems in the assignment that is still manual. Data collection is done on unit union pipe with average work per day. The problem is found in the union pipe unit with the manual assignment. Observations made on 4 people for cutting pipes, chamfering, stamping, and packing. Results of observations then performed data processing using Hungarian method, so that the optimum unit is generated per hour as much as 8.125. Furthermore, data processing was performed using PERT method with the result stated that the optimum working order was A-B-C-D-E with total processing time for 5,000 units for 16.5 hours. The last data processing using CPM method can be seen that the acceleration time as much as 8 hours from the initial time is 16.5 hours with the total crash cost of 4,000,000 IDR from the allocated fund of 4,225,000 IDR. From some data processing, it can be seen that there is an optimization in the assignment and network work. Therefore, in accordance with the existing theories and objectives of this research, namely to optimize the existing human resources for the work done equally and minimize the losses due to unemployed use of these methods can be used as a reference in the making of the schedule, so as to facilitate the course of the project to know the delay in every process.
