Abstract

PT. Shima Prima Utama, is an industry that produces medical devices. During practical work and making observations there were problems in the chrome plating division. Constraints that occur at PT. Shima Prima Utama is the occurrence of defects in components that go through the chrome division. The method used is the PDCA (Plan, Do, Check and Action) method, to find the cause of the problem in the chrome division. From the results of observation and analysis found several factors that cause defects, namely material content, current strength, air, and temperature. So as to prevent defects from occurring again, it is better to include standard amounts of material grades, one of which is in the semi-bright section, the normal nickel content is in the range of 68 – 80 gr/l, the optimum is around 73 – 75 gr/l, and in the chrome section hexavalent with a standard value of 200 – 350 gr/l, so that the current strength remains stable you can use a stabilizer. Air and dirt in the tub can be cleaned with a filter or washing the tub, the temperature that is not right can be raised to a standard temperature.
