PENGENDALIAN KUALITAS PADA HOME INDUSTRY MOBIL MAINAN TRUCK TANGKI di PT. SELAMAT SENTOSA

Abstract

Quality control is conducted so the product or service which are being produced could have a result that matched the standard that are desired and planned, also to fix product quality which are not matched yet with the standard that already have been set and wherever possible maintain quality which are fit. Companies need some way to realize the good quality on products that are they produce and maintain the consistency so it fulfill the market demands with implementing quality control system for process activity which is being passed. Control map is usually being used to map flawed items or the number of flawed items from a sample which is taken beforehand. In contrast with the p control map which could map the process with the number of sample in each equal or inequal observation, np control map could only being used when the taken sample from each observations have the same amount. This research draws whether flaw on production process   still in the control threshold or not, and how many size variety ins the controlled threshold or not. After the data processing on PT. Selamat Sentosa, the result shows that attribute control map   is not yet on the threshold control that iterarion have to be done and variable control map still on the control threshold. The result shows that CP number is 1.8, which is more than 1.33, so it shows a very good result, dimension which is tolerated is 99.999986%, dimension that reworks is 0.000014% and dimension that are denied is 0.000007%. Tight control is required because CPK <1.00.
