Abstract

PT. X is a company engaged in the production of electrical and electronic equipment, one of its products is camera. This research aims to compare the inventory policies that have been implemented by the company with other dynamic deterministic models. In the production process, the company uses a stock policy with the Lot for Lot (LFL) method, but the total costs incurred by the company and the frequency of ordering are still quite high. This research aims to compare the inventory policies that have been implemented by the company with other dynamic deterministic models, such as Period Order Quantity (POQ) and Economic Part Period (EPP) methods so that the optimal inventory method can be determined. The results of this study indicate that the Economic Part Period (EPP) is the optimal method with a total cost of Rp. 69,284,600 and the order frequency is 7 times.

Abstract

Inventory control needs to be done to meet customer demand but also consider the costs that can be incurred. Inventory needs to be managed properly to minimize the inventory costs incurred. PT XYZ is a company engaged in the supply and distribution of gas. This study aims to compare the inventory control of oxygen gas products for filling 1 m3 cylinders with the Least Unit Cost, Least Total Cost, and Silver Meal methods. Comparison of inventory policies is carried out by considering the total cost of inventory to obtain the method that gives the smallest total inventory cost. Based on the results of data processing and analysis that has been carried out, it is obtained that the inventory policy using the Silver Meal method provides the smallest total inventory cost compared to the other two methods, namely Least Unit Cost (LUC) and Least Total Cost (LTC). The total cost generated by using the Silver Meal method is Rp. 145,560. As for the frequency of orders generated by the Silver Meal method, namely twice for twelve months. Pengendalian persediaan perlu dilakukan untuk mencukupi permintaan pelanggan namun juga tetap mempertimbangkan biaya yang dapat ditimbulkan. Persediaan perlu dikelola dengan baik sehingga dapat meminimalkan biaya persediaan yang ditimbulkan. PT XYZ merupakan perusahaan yang bergerak pada bidang penyediaan dan pendistribusian gas. Penelitian ini bertujuan untuk membandingkan pengendalian persediaan produk gas oksigen untuk pengisian tabung ukuran 1 m3 dengan metode Least Unit Cost, Least Total Cost, dan Silver Meal. Perbandingan kebijakan persediaan dilakukan dengan mempertimbangkan biaya total persediaan sehingga diperoleh metode yang memberikan biaya total persediaan terkecil. Berdasarkan hasil pengolahan data dan analisis yang telah dilakukan, maka diperoleh hasil bahwa kebijakan persediaan dengan menggunakan metode Silver Meal memberikan biaya total persediaan terkecil dibandingkan dengan dua metode lainnya yaitu Least Unit Cost (LUC) dan Least Total Cost (LTC). Total biaya yang dihasilkan dengan menggunakan metode Silver Meal adalah sebesar Rp 145,560. Sedangkan untuk frekuensi pemesanan yang dihasilkan dengan metode Silver Meal yaitu sebanyak dua kali selama dua belas bulan.

Abstract

Manajemen inventori merupakan hal yang perlu dilakukan oleh perusahaan guna memenuhi permintaan konsumen. Namun demikian, penentuan kebijakan inventori optimal perlu dilakukan sehingga dapat mengurangi ongkos total yang dihasilkan. PT X merupakan perusahaan distributor logam, dengan salah satu produknya yaitu baja. Permintaan produk baja bersifat probabilistik sehingga untuk penyelesaiannya dapat menggunakan model probabilistik. Kondisi pemenuhan permintaan bersifat backorder. Penelitian ini bertujuan untuk membandingkan kebijakan inventori optimal dengan menggunakan model Q-backorder, model P-backorder, dan kebijakan perusahaan. Perbandingan kebijakan inventori optimal dilakukan dengan mempertimbangkan ongkos total yang terendah. Berdasarkan hasil pengolahan dan analisis data yang dilakukan, diperoleh hasil bahwa kebijakan inventori yang paling optimal yaitu dengan menggunakan model P-backorder. Estimasi ongkos total per tahun yang dihasilkan dengan kebijakan inventori model P-backorder yaitu sebesar Rp183.536.949.251,00 dengan tingkat pelayanan sebesar 95,1%. Jika dibandingkan dengan kebijakan inventori yang dimiliki perusahaan, estimasi ongkos total dengan model P-backorder lebih rendah sekitar Rp1,1 milyar per tahun. Oleh karena itu, kebijakan inventori dengan model P-backorder dapat mengurangi estimasi ongkos total per tahun yang akan dikeluarkan oleh perusahaan.

Abstract

The bakery industry in Indonesia shows increasing development. One of the activities carried out by this industry is processing customer orders. Currently, there are still bakery industries where customers order products manually, either by coming directly or by using a telephone or WhatsApp. Manual product ordering causes several problems that can hinder business activities and will have an impact on customer service. This study aims to design an Android-based product ordering application in the bakery industry. The application design uses the Multimedia Development Life Cycle (MDLC) method. The application design stage consists of six stages, namely concept, design, material collecting, manufacturing, testing, and distribution. The results of this study are in the form of an Android-based product ordering application that uses multimedia to provide detailed information related to products and has interactive features to respond to customers quickly. In addition, this application can also generate a summary report of customer orders via the Dashboard. The application that has been designed is expected to support bakery industry players to manage and monitor product ordering performance and improve customer service.
