Abstract

PT.X is a company engaged in offset printing industry. The company is located in Sidoarjo, East Java. Production process based on customer order, if there is a new order will be produced based on the ordered quantity. PT. X requires the allocation of the optimal number of operators so that the input and output of the production line can run in balance. PT.X has 37 operators allocated to each process. The allocation of operators is still a constraint and causes the production path becomes less balanced. The proposed improvement is to provide a proposed lane balancing design on the production line. Allocation of operator to production line by maximizing operator without adding new operator. Allocation of operators can improve the resulting good finish. The production output of the allocation produces 31632 sheets of paper within one hour of the production process. Total operators allocated as many as 37 operators. These outputs result in more than 20187 sheets of paper if compared with not allocating operators.

Abstract

Competition in the industrial world forcing every company to have a strategy in their production process. Layout arrangement is one of the strategy that can be done so that the production process can run more efficiently. Two strategies that can be used in the layout arrangement are product layout and process layout. The initial layout, product layout, and process layout will be simulated by using Promodel software. Research in this final project will determine the best layout through the comparison of the four factors which are output of products, transportation time, operator utility, and moment. These results indicate that the process layout is better when compared with the initial layout and product layout of the four factors above. Comparison with the initial layout show that the product output from process layout can be increased by 37.49% for can product and 55.22% for lid product. Average transport time on the process layout can be decreased by 88.97%. The average operator utility on the process layout can be increased by 41.81%. Moment of the process layout can be decreased by 53.80%.

Abstract

PT. X is a manufacturing company that manufactures dermatological products. Inventory of raw materials becomes an important factor in production activities. This research focuses on the inventory and arrangement of  tube materials in the warehouse. The company is currently purchasing goods by estimating demand from past data and ROP. Determination of ROP and EOQ is done by using a simulation method. The results of simulation of raw material inventory show the total cost of proposed inventory and the percentage of shortage is better. The initial total cost of inventory is Rp3,616,786,638 and the proposed condition is Rp1,736,032,454. The inventory simulation results will be used to make for raw material arrangement layout proposal. The arragement proposal for tube materials is done by sorting fast moving products and slow moving products. Fast moving products are arranged with a dedicated storage policy, while for slow moving products are arranged with class based storage policy. The order of placement of each type of tube is based on the highest number of stocks. The arrangement proposal is better than the initial conditions based on warehouse utility and moments. The average warehouse utility increased by 1.82% and there was a reduction in the initial layout moment by 64.55%.
