Abstract

GMF Aeroasia Tbk. merupakan sebuah perusahaan jasa yang berjalan dibidang repairing dan maintenance pesawat. Salah satunya adalah pocket spring. pocket spring berada dibagian belakang kursi penumpang yang berguna untuk rangka tempat penyimpanansafety book aircraft. Selama ini barang tersebut biasa diimport dari luar negeri dengan harga yang cukup mahal juga dengan waktu pengiriman yang tidak singkat. Secara perlahan PMA (Parts Manufacturer Approval) mencoba untuk memproduksi sendiri pocket spring. Akan tetapi untuk menentukan harga produksi PMA masih menggunakan metode konvensional. Time Driven Activity based Costing menawarkan solusi untuk menghitung harga pokok produksi menjadi lebih akurat. Harga pokok produksi dapat dihitung dengan mengetahui terlebih dahulu biaya kapasitas produksi dan kapasitas sumber daya yang digunakan. Untuk biaya langsung dapat langsung diketahui namun ,untuk biaya tidak langsungnya dilakukan pengamatan secara langsung terhadap model estimasi unit per waktu Harga pokok produksi pocket spring yang ditetapkan oleh perusahaan mengalami undercosting atau terlalu rendah kurang dari seharusnya. Metode konvesional perusahaan menetapkan hasil Rp. 202.0458,00/pcs, sedangkan metode time driven activity based costing mendapatkan hasil sebesar Rp. 209.877,00/pcs. Laba produk ditentukan dari markup percentage yang didapat dari target profit perusahaan dibagi dengan hasil kali volume prosukdi dengan harga pokok produksi. Hal ini yang mengakibatkan harga pokok produksi sangat mempengaruhi besarnya laba.

Abstract

PT. Apie Indo Karunia is one of the companies engaged in the foundry located in Sidoarjo. The company itself is a company that works by order / orderan from the consumer (Make to Order). Some of the products produced are gears, industrial machinery parts, and other steel construction. Products that have serrations are used as research material because of the high level of product order quantity. In this case the problem is the existence of flow back and forth process, so that the emergence of overtrasnsportation that can increase the cost of material handling and also affect the waste of time just for the process of removal. The cause of this alternating flow is because the layout of the machines is irregular (not in accordance with the process of making the gear and does not consider the type of production process of the company in the type of jobshop), where the engine layout should be grouped according to function. In addition, from the irregular arrangement of machines causes a pile of material / product (no special space for products that are queued up or processed). To handle the problem, used Methodatic System Layout Planning (SLP) developed by Richard Muther. The first step is to input data, then make Flow Process Chart, distance, time and speed of material transportation, make Activity Relationship Chart, and Activity Relationship Diagram. Result of research of layout design result 3 layout alternative then chosen one layout proposal selected with nlai cost and distance of best move with total distance material handling 5117,17 m / month and material handling cost every month equal to Rp 1.479.724,- So it can increase the efficiency of material handling cost (OMH) by 54%.

Abstract

Project is a production process that is unique, and is carried out within a certain period of time with limited resources to achieve the targets set. Steel Structure - Primary Crushing is one of mining company’s projects in East Java and is carried out by PT. Lintech Duta Pratama. But this project is past the specified deadline These lateness have consequences like fines or decreased client’s trust toward company’s performance and affect completion for other projects. Optimization is needed to avoid delays. The scheduling method used is a Precedence Diagram Method (PDM) that simpler for overlapping activities. To get a shorter duration of project completion, acceleration (crashing) analysis must be done. The results of the study obtained the duration of acceleration from 143 days to 125 days. The acceleration has two alternative, with overwork that increased the costs by 8,97% from the normal costs. While the other alternative is to add more worker that increased the costs by 0,65%. The cost of increasing the worker is lower so that alternative has the optimal cost and time.

Abstract

Assembly lines that have poor efficiency result in various problems in the production process, one of which is the bottleneck problem. PT. Pindad (Persero) as a manufacturing company, has problems in the assembly line for special vehicles, where the efficiency of the assembly line has an unclear and uneven distribution of workloads, this results in poor production efficiency. This study aims to valuate the efficiency of PT. Pindad (Persero) and produce alternative improvements. An evaluation of the Komodo tactical vehicle product assembly line was conducted using line efficiency, balance delay, and smoothest index. It is known that the existing assembly line has a line efficiency of 13.25%, a balance delay of 86.75%, and a smoothest index of 875.31. Then the line balance is improved using heuristic line balancing methods. The methods used include the largest candidate rule, ranked positional weight, and regional approach. The results of this study are recommendations for special vehicle assembly lines using the line balancing ranked positional weight method with a line efficiency value of 94.1%, balance delay of 5.9%, and smoothest index of 8.86.

Abstract

Abstract - Train door is one of the projects undertaken by PT INKA Multi Solusi. This project was expected to be completed on time, but actually it was delayed. The methods used in this research are the Critical Path Method (CPM) and Project Evaluation Review Technique (PERT). The CPM and PERT methods are suitable for scheduling in order to obtain the fastest completion time by considering the estimated completion time of the project due to the uncertainty that occurs in the field, so that the percentage of possible completion of the project is obtained. The results found that the probability of delays in the planned schedule is 61.41%. To overcome this delay, it is necessary to accelerate the duration using an alternative 4 hours of overtime. Based on the analysis of the Time Cost Trade Off method, the optimal time and cost of the train door's production on the MYC 2020 measuring train's project was obtained, namely the acceleration of duration to 199.6 days with total cost of Rp 462,280,692,-. Based on the Swent under the curve of the plan duration because the completion process was delayed so the time required was longer than the plan.
