The Objective of this research was to improve the productivity and efficiency in a line process of a case study. The observation showed that current efficiency was about 87% and operator productivity was about 13.3 pcs/hour/man power. Productivity improvement can be reached by three step. First, identification and reduction of non-added value activity. There are 13 non value added activities which are prioritized to be eliminated based on Pareto principles. Second, the reduction number of operators while doing the third step: reallocate the work of each operator after reduction. Operator reduction is done from 3 to 2 operators only. Then the job that is already efficient from the stepped operator is moved to two other operators. After repairing and balancing tasks for each operator, the efficiency value becomes 96% and productivity increases to 20.5 pcs/hour/man power and man power savings to two men power.
