PT. XYZ is one of the company's units in a manufacturing industry engaged in facility maintenance and installation. So far, PT. XYZ applies the Just In Time (JIT) method in the inventory control process, but it is not yet known whether this method is the most efficient and appropriate method to be applied to all types of material inventory in PT. XYZ. The purpose of this study is to determine the classification of each item in the inventory based on its priority level. This research method uses the ABC (Activity Based Costing) method, which determines the critical level of investment, material use, the order of the value of money from largest to smallest to material, performs a percentage of money value and material value. There are findings in this study, namely the JIT method that has been applied by the company is appropriately applied to several types of materials, namely materials that fall into category C. However, this JIT method is not appropriately applied to materials that fall into categories A and B because this type of material must always be available in the warehouse. Thus, PT. XYZ can determine the consideration of other inventory methods on materials in categories A and B. It is proven that the ABC method can be applied in controlling continuous control activities to streamline material inventory.PT. XYZ merupakan salah satu unit perusahaan dalam sebuah indsutri manufaktur yang bergerak dalam bidang pemeliharaan fasilitas dan instalasi. Selama ini PT. XYZ menerapkan metode JIT (Just In Time) dalam proses pengendalian persediaannya, namun belum diketahui apakah metode tersebut merupakan metode yang paling efisien dan tepat untuk diterapkan terhadap semua jenis persediaan material yang ada di PT. XYZ. Tujuan penelitian ini yaitu untuk mengetahui klasifikasi setiap barang pada persediaan berdasarkan tingkat prioritasnya. Metode penelitian ini menggunakan metode ABC (Activity Based Costing) yaitu menentukan tingkat kritis investasi, penggunaan material, urutan nilai uang dari terbesar ke terkecil terhadap material, melakukan presentase nilai uang dan nilai material. Terdapat temuan dalam penelitian ini yaitu metode JIT yang telah di terapkan oleh perushaaan sudah tepat diterapkan kepada beberapa jenis material, yaitu material yang masuk dalam kategori C. Namun, metode JIT ini kurang tepat di terapkan terhadap material yang masuk dalam kategori A dan B karena jenis material ini harus selalu tersedia di dalam gudang. Dengan demikian, PT. XYZ dapat menentukan pertimbangan metode persediaan lain pada material dalam kategori A dan B. Terbukti bahwa metode ABC dapat diterapkan dalam mengontrol aktivitas pengendalian yang berkelanjutan untuk mengefisiensikan persediaan material.

The increasing demand for filling oxygen cylinders makes CV. Tasman Gases has always been consistent in planning transportation cost optimization strategies. The filling of oxygen cylinders in one distribution can transport up to 45 tubes sent to the concerned partner. The purpose of this study is to determine the shortest route and optimal cost in distributing. The method used is Complete Enumeration. The samples used include distribution locations and mileage. The procedure used begins with determining the number of routes, estimated mileage and fuel costs. There is the most optimal route selected from the 12 modeled routes. The selected route has the least transportation costs. This research makes CV. Tasman Gases has the best route, A-D-C-E-F with a distance of 10.9 km worth Rp. 10,423.13. This value is more effective than the existing A-E-C-D-F condition with a distance of 12.8 km obtaining fuel costs of Rp. 12,240.00. Thus, the distribution route and costs that have been optimal make CV. Tasman Gases can implement and identify future transportation constraints.

Distributors are parties who play an important role in trade because distributors are intermediaries between producers and consumers. PT Surya Mandiri Distribusi is a company engaged in the distribution of cooking oil. In distribution activities, this company often experiences product stock discrepancies which results in a high bullwhip effect phenomenon. This study aims to minimize the bullwhip effect that occurs in cooking oil distributor companies. This study used the Distribution Requirement Planning (DRP) method to solve the problems in this study. Where this method aims to set the distribution schedule as well as plan the number of products and their delivery time. The results of this study found that the application of the DRP method can reduce the value of the bullwhip effect in PT Surya Mandiri Distribusi by 17%. The application of the DRP method to distribution activities at PT Surya Mandiri Distribusi not only facilitates the planning of goods for future needs but is also one way that can minimize the value of the Bullwhip Effect that occurs in the company.Distributor merupakan pihak yang memegang peranan penting dalam perdagangan karena distributor merupakan perantara antara produsen dan konsumen.
