Abstract

PT Jati Kawi Group is a heavy equipment provider, contractor, and sand mining company located in Sukabumi, West Java which one of its sources of income comes from sand mining. So far, the company has not analyzed the productivity of transporting sand from the warehouse to the factory. Based on data from 2021 that the delivery of silica sand from the warehouse to 3 companies, namely those abbreviated to SK, IC, and IP, shows that the percentage of silica sand delivery shortages from demand and planned to the SK factory is 0.249%, to the IC factory by 0.005%, and the IP factory by 0.221%. That means the fulfillment of silica sand needs against demand to 3 factories has not reached the planned amount and has not met demand. Based on the above data, it is necessary to analyze productivity using the match factor method between the production level of the sand mine with the conveyance and loading equipment to the factory and then analyze the causes of the problem and how to overcome it. From the results of research using the match factor method on the transportation of sand mines from the warehouse of PT Jati Kawi Group to the destination factories of PT SK, IC, and IP shows a match factor (MF) value of 0.87. Thus the value MF < 1, meaning that the loading equipment works less than 100%, while the transportation equipment works 100%, so it is said that the productivity of the loading equipment is not good because there is waiting time. The result of the lack of productivity in sand transportation is that there are several influencing factors, namely humans, methods, processes, machines, and the environment.
