PENGENDALIAN KUALITAS KABEL LISTRIK PIILN UDARA DENGAN MENGGUNAKAN ANALISIS METODE PDCA

Edit
ABSTRACT: This researh explained about how to reduce the defects or failure in the end product power cable NFA2X 2x10 mm ² 0.6 / 1 kV which include : " Defect Appearance" ie, defect or damage is visible on the surface or physical appearance of the cable, such as insulation thickness , color insulation and defect marking , with this type of defect by 4 % and " defect function " ie, defects or damage cause a malfunction of the cable as well, breaking the cable conductor of 0.5 %, conductor resitance > standard of 1% and a breakdown voltage of 34 %. Defect or failure is the most dominant breakdown voltage test " caused by insulation failure at one point on the cable to withstand the test voltage of 3.5 kV given / AC for 5 minutes in accordance with the standards SPLN 42-10 1993 .
Improved results of the analysis conducted on the electrical wiring NFA2X 2x10 mm ² 0.6 / 1 kV using PDCA 8 ( Eight ) steps and aids statistics, the results obtained from the two different methods were carried out, ie the percentage decrease in the level of failed test breakdown voltage of 19.7 % in getting from before improvement by 34 % with the total cost of repairs Rp 3,405,888, - and after repair using the first method was 14.3 % with a total repair cost of Rp 1,376,352, - so the reduction in repair costs incurred by the company amounted to Rp 2,029,536, - with the percentage decrease costs by 60 %. Improvements to the second method in getting a decrease of 11.8 % from the prior percentage improvement of 34% with a total repair cost of Rp 3,405,888, - and after improvement of 22.2 % with a total repair cost of Rp 1,516,320 , - and a reduction in repair costs incurred by the company amounted to Rp 1,889,568, - the percentage rate of cost reduction by 65 % . From these results it is known that the factors causing the failure of the test comes from the 5 factors, namely : humans, machines, methods, materials and the environment, with the most dominant cause of the factors derived from the method used, ie high temperature in zone 5,6 and 7 801 extrusion machines .
Keywords: PDCA 8 steps, breakdown voltage, saving cost.
