Perancangan Tata Letak Stasiun Kerja dengan Menggunakan Metode Systematic Layout Planning

PT. Adhimix Precast Indonesia is engaged in the construction sector by producing concrete and construction. Layout design is needed so that the existing land can be utilized optimally and material transfer is more effective and efficient. This can affect the distance and time of the transfer so that the cost of moving can be minimized. In practice, the company's trajectory condition only has one path (trajectory) for alternating current and crossing production lines, so it is considered inefficient to move both goods and workers, coupled with the existence of land that is not used properly, therefore improvements are needed to the production floor layout. in order to minimize the cost of moving goods and have a definite path (trajectory). Systematic Layout Planning (SLP) is a method for redesigning a layout (re-layout) based on the results of distance optimization and Material Handling Costs (OMH). The amount of OMH in the initial layout (now) is Rp. 2,614,200 with a total track distance of 39.82m and OMH in the proposed layout with a total track distance of 19.17m, the result is Rp. 1,534,200, this proves that the proposed layout can be applied because there is a decrease in total OMH by 35.44% or Rp. 926,580. PT. Adhimix Precast Indonesia bergerak di bidang pembangunan dengan memproduksi beton dan konstruksi. Perancangan tata letak diperlukan agar lahan yang ada dapat dimanfaatkan dengan maksimal dan pepindahan material lebih efektif dan efisien. Hal ini dapat mempengaruhi besar jarak dan waktu perpindahan sehingga besar biaya perpindahan dapat diminimalkan. Pada pelaksanaannya kondisi lintasan perusahaan hanya memiliki satu jalur (lintasan) untuk arus bolak balik dan persilangan alur produksi maka dianggap tidak efisien untuk dilakukan perpindahan baik barang maupun pekerja, ditambah dengan adanya lahan yang tidak dimanfaatkan dengan baik oleh karena itu dibutuhkan perbaikan pada layout lantai produksi agar dapat meminimalkan biaya perpindahan barang dan memiliki jalur (lintasan) yang pasti. Systematic Layout Planning (SLP) merupakan metode untuk membuat perancangan ulang suatu layout (re-layout) berdasarkan hasil dari optimalisasi jarak dan Ongkos Material Handling (OMH). Besar OMH pada layout awal (sekarang) adalah Rp 2.614.200 dengan total jarak lintasan 39,82m dan OMH pada layout usulan dengan total jarak lintasan 19,17m didapat hasil sebesar Rp. 1.534.200, hal ini membuktikan bahwa layout usulan dapat diterapkan karena terjadi penurunan total OMH sebesar 35,44% atau Rp.

FACILITY LAYOUT REDESIGN USING SYSTEMATIC LAYOUT PLANNING METHOD IN PT. PILAR KEKAR PLASINDO

Good equipment and product design are meaningless if there is no good layout planning. Problems owned by PT. Pilar Kekar Plasindo occurs in the production of small polyethylene. This is because small polyethylene production has large material total transfer distance. Small polyethylene problems include the distance between stations, cross-movement, backtracking, and the broken machine that is still placed in the production section. These conditions make the material handling costs and distance large. Therefore, this research aims to produce a layout design of production facilities that can minimize the distance and cost of material movement. The method used in this study is Systematic Layout Planning (SLP). Three alternative designs were compared, and the second proposed facility layout was chosen because it can reduce the total cost of material transfer by 68.3% and reduce the distance of material transfer by 59.6% from the initial facility layout.

Sosialisasi Usulan Perancangan Tata Letak Pabrik Pada PT Sari Kayu, Jakarta Timur

The problem faced by PT Sari Kayu is that fluctuating production demand and high product variance make production inefficient. If the problem does not have a good factory layout, it affects material handling costs, material handling distances, and material handling time. For example, at PT Sari Kayu, there was a delay during a wrong project because the two projects were running simultaneously. The delay is due to the lack of resistance of the production floor to sudden high fluctuations in production demand. In addition, product variance is also a factor in the longer production process due to the different sequence of production processes and less supportive machine layouts. It is hoped that with the proposed layout, PT Sari Kayu will be able to face the fluctuating demand for production.

Analisa Perbaikan Tata Letak Penempatan Bahan Bakudi Area Gudang Penyimpanan

Activities carried out in the warehouse include material handling. Generally, the costs involved in material handling activities are quite large. One method that can be used in managing the layout of raw material placement in raw material warehouses is the class based storage method. Class based storage is a policy that divides storage into three classes A, B and C based on Pareto law. Pareto law is the principle of putting items that have the greatest accessibility near the Input-Output point. The distance of material handling to the initial layout raw material warehouse is 3,513,337 meters / month and the material handling costs are Rp. 134,534,765 / month, because the initial layout of the raw material warehouse still uses random storage and the raw materials that are widely used are not placed close to the intake floor of the production, so that the distance to get raw materials for production needs is far. After the re-layout design was made based on the placement of raw materials in the class based storage method, the material handling transfer distance was reduced to 2,644,459 meters / month and the material handling cost for the repair raw material warehouse layout fell to Rp. 99,949,520 / month. In other words, there was a decrease in material handling distance by 25% and material handling costs by 26%.

Minimizing Material Handling Costs with the SLP Method and Material Transport Equipment in Steel Pipe Companies

Factors that influence the amount of material handling costs are the distance of material movement, methods, and tools (equipment) used. The distance of material movement is strongly influenced by the layout of the production facility. The new layout design using the SLP method is expected to reduce the distance of material or product movement in PT. A B C. From the analysis results obtained the total distance of material transfer at the initial layout of the production process at PT. ABC of 1761 meters / month with material handling costs of Rp. 315,390,000.00 / month. Then an analysis of the use of material transport equipment results in the replacement of a crane with a sloping plane to connect the production machine. So the cost of material handling using the inclined plane becomes Rp. 0. The use of sloping fields can only be used on certain production machines. By using the Systematic Layout Planning (SLP) method, there are 3 alternative layouts produced. The most optimal alternative layout is alternative layout 3 with monthly material handling cost savings of Rp. 68,100,000.00 or 21% of the initial material handling layout cost.

Prayer paper production facility layout redesign using systematic layout planning method and CRAFT

The facility layout is a strategic design that is used for a long time. All manufacturing industries must pay attention to the right layout to increase the productivity of the industry. A prayer paper manufacturing industry located in the Tanjung Morawa area, Medan has an error in the placement of raw materials and the placement of production machines, so that the distance from the temporary warehouse to the printing and cutting work stations is far apart, causing high material handling costs. Seeing these problems, research was carried out to improve the layout of the facilities and redesign. The method used for this research is Systematic Layout Planning (SLP), which is one of the methods used to regulate a workplace in a factory by using two areas with high frequency and logical relationships with each other. And the Computerized Relative Allocation of Facilities Technique (CRAFT) Algorithm is a repair program, which is a program that looks for optimal design by making gradual improvements to the layout. CRAFT evaluates the layout by interchanging departmental locations. Inputs required for the CRAFT algorithm include initial layout, data flow or frequency of movement, cost data per unit distance, and the number of departments that do not change or remain. The CRAFT method is usually applied using Quantitative Systems (QS) software. By comparing the layout between SLP and CRAFT, the optimal result is obtained using the SLP method by reducing the distance between departments by 1.407 meters or a distance efficiency of 39.91%.
