Pengendalian Kualitas Batu Pancing Dengan Metode Failure Mode and Effect Analysis (FMEA) dan Metode Fault Tree Analysis (FTA) di PT. Cahaya Castindo Hasanah Cemerlang

Abstract

PT. Cahaya Castindo Hasanah Cemerlang is a company engaged in the scrap iron and metal processing. The product quality produced is the main thing in the iron processing. The research at PT. Cahaya Castindo Hasanah Cemerlang was conducted by Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA) Methods, where both methods used to investigate the initial location of the defect source. This research will compare which the better method used in analyzing the product defect of the rock of fishing rod at PT. Cahaya Castindo Hasanah Cemerlang. The product defects found are nonstandard weights (0.9 kg – 1.1 kg), perforated and dented products or unfit shape. Then, the defect percentages of each kind of the defect are 37% for dented defect/ unfit shape, 34% for perforated defect, and 29% for nonstandard weights (0.9 kg – 1.1 kg). The result showed that it is better to use Fault Tree Analysis (FTA) method because it discusses as a whole up to the source causes of the product defects problem, namely the minimum of cut set and giving the improvement suggestions corresponding to the problems source found. Whereas, the Failure Mode and Effect Analysis (FMEA) only discuss Risk Priority Number (RPN) of each defect, those are 20. 244 and 256 also only prioritize the highest risk priority number value.
