Abstract

Production system take an important role in industries, especially in manufacturing industries. This role determine the keys of successful company. Production process is an activity which produce finished product from raw material that involve machine, energy, and technique knowledge. Production process is real activity and can be seen by human being. The problems those always be faced in indutries management’s are the arrangement of production schedule, such lack of inventory or overstock once the settlement of production process isn’t on time. Production planning and control is activity to determine what product that will be produced, how many product that will be produced and how many labors needed in production processes. By using production planning and control’s method, those problems can be minimalized. Aggregate planning is one of production planning a.nd control’s method. By using this method, production planning could be done by using unit of replacement product so that the output of this planning isn’t declared in individual product. So, the output of aggregate planning isn’t planning in form of individual product but aggregate’s product. There are some strategies on aggregate planning such as pure strategy on aggregate planning and mixed strategy on aggregate planning. In this research, method of aggregate planning that used is optimization approach by linier rule. This method used to make long term planning and middle term planning. Long term planning consists of product forecasting and aggregate planning. The middle term planning consist of master production schedule and rough cut capacity planning. The result of this research is capacity needed and capacity available to determine which work center is drum and which isn’t. Conclusion of this research that capacity of each work center in perioad january to december 2018 is non drum. This indicate the good scheduling in capacity planning.

Abstract

Indonesia Port Corporation I (PT Pelabuhan Indonesia I (Persero)) or PT. Pelindo I is one of the Indonesian state-owned enterprises which manages port services in western Indonesia. Shipyard unit (Unit Galangan Kapal (UGK)) is a branch of PT. Pelindo I. At present, a problem arises if more than 2 ships are being repaired at once in the unit, UGK scheduling overlaps the repairing activities. In order to solve the problem, study of human factor is important. Human factor is the study of the limitations, capabilities, and human behavior, as well as its interaction with the product, environment, equipment and the establishment of tasks and activities. One part of the human factor is the human factor in system design. In order to improve the effectiveness of the system, the human factor must be involved in each phase of the design process in the system design. This includes a number of activities to obtain input specification work, therefore the working methods and the optimal amount of labor can be determined. Human factors engineering is the application of science that utilizes research on the human factor and use the basic knowledge to design, to repair and to install the system. This research method is causal, searching for the causes which led to delays in the completion of ship repairing. Through human factor engineering approach to the allocation of labor increased by 12.23 per cent of the actual conditions, so that the delay of ship repair were not found during normal conditions.
