PT Pacinesia Chemical Industry is a company engaged in the production of water treatment chemicals, namely PAC (Poly Aluminum Chloride). PAC is used to produce material that consists of one HCL acidic and highly corrosive. The nature of this acid causes all material that is metal / metal in the production area becomes corrosive, good production machinery, buildings, until the other supporting equipment. This led to a period to all the equipment and machinery to be faster. Especially in this study will be discussed issues of demand for goods sudden / urgent are often carried out by a team of maintenance-related damage on a production machine. The purpose of this study is the Knowing the causes of the frequent requests for urgent assistance from a team of maintenance items and choose the best strategy to reduce the demand for goods urgent spare parts from maintenance team using Soft Systems Methodology approach. Soft Systems Methodology With this approach it can be arranged and tndakan langkag measures taken to reduce the demand for goods urgent, namely by providing knowledge to the maintenance of the documentation team and special treatment machine engine against corrosive environments.
