Abstract

PT. Trias Sentosa is a flexible packaging film manufacturing company. Customers who buy from PT. Trias Sentosa gives the demand in form of film type, length, width, thickness, and number of rolls for each type and dimension of the film. In loading the demand into containers, there are several steps to be taken.The first step is to calculate the dimensions of each roll from the length, width, and thickness of the film the customer requested. The rolls are then arranged into pallets according to the policy of the company, as well as searching pairs of pallet to be stacked but not exceeding the height of the container using Greedy Algorithm principle. The second step is to distribute each pallet group evenly into the container. The third step is to arrange the loading order of each container by using Simulated Annealing method and calculate the weight distribution of each container.

Abstract

PT. SPS has an ineffective finished materials warehouse layout. This is because the layout of the company is only based on the customer. Therefore the research aims to make the layout more effective by reducing the moment of material handling equipment. Making this layout is based on customer priority where customer priority is obtained from the total tonnage of storage in the warehouse. Apart from the layout, PT. SPS also does not apply the FIFO concept. This is due to the absence of directives and an easy way to read data to differentiate jumbos with old and new production dates. In order to improve the application of FIFO, an evaluation is held every week to monitor jumbo shipments. Besides that, a warehouse stock appearance is modified by adding production dates and providing colour indicators to make it easier to distinguish old and new production dates. The new layout can reduce the moment by 8.7% or 59,906 meters/month. This is because customers who have high priority have a closer distance to I/O so that it will reduce the moment of material handling equipment.
