Abstract

This research describes an electronic Kanban system development in order to replace conventional Kanban system. Many previous research conducted to optimize number of Kanban, however weaknesses still find when there is a change condition of production planning, therefore it must be re-optimization number of Kanban and it will takes time and costs. In current condition, the Company has implemented a manual Kanban system to support their  Just In Time production system, but unfortunately it still find problems during implementation due to the system implemented using paper and manual recording. In this research, the electronic Kanban system (e-Kanban) is develop based on computer vision which combined with production systems condition in currently. E-Kanban system is a method to replace manual Kanban irregularity. Based on result through a scenario Master Production Schedule (MPS), Electronic Kanban system can deliver information effciently and effectively with improve 54% compared with conventional systems and 32% compared with manual Kanban.

Penelitian ini bertujuan untuk mengendalikan persediaan bahan baku menggunakan metode EOQ di PT Bina Busana Internusa. Penelitian ini menggunakan metode EOQ untuk mengetahui total biaya persediaan. Data yang dibutuhkan pada penelitian ini yaitu jumlah pembeliaan bahan baku, jumlah penggunaan bahan baku, biaya simpan, biaya pemesanan, lead time dan frekuensi pemesanan . Hasil yang diperoleh dari metode EOQ yaitu terjadi perbaikan pada pembelian bahan baku, total biaya persediaan bahan baku, frekuensi pemesanan, safety stock dan reorder point. Nilai pembeliaan bahan baku sebesar 1.313,167 kg menjadi 1.837 kg. Nilai total biaya persediaan bahan baku sebesar Rp 2.447.395 menjadi Rp. 2.315.356. Nilai Frekuensi pemesanan sebesar 24 kali menjadi 17 kali. Safety stock yang di hasilkan dari metode EOQ sebesar 749,91 kg. Reorder point yang dihasilkan dari metode EOQ sebesar 969 kg. Oleh karena itu, perusahaan disarankan untuk menimasi total biaya persediaan bahan baku.

Abstract

This study aims to determine the comparison of order determination on camera lens components and the costs incurred between company policies and dynamic deterministic methods. This study uses dynamic deterministic methods, namely Wagner-Whitin Algorithm, Silver Meal, Least Unit Cost, Economic Part Period, Lot For Lot and Least Total Cost to determine the amount of costs incurred by the company each time the order on the camera lens component. Of all these dynamic deterministic methods, the most efficient is the Wagner-Whitin Algorithm method with an order frequency of 10 times the order and the cost incurred is Rp. 34,529,190. The Silver Meal method with the order frequency of 10 times the order and the cost incurred is Rp. 35,390,310. Least Unit Cost method with the order frequency of 10 times the order and the cost incurred is Rp. 35,234,830. The method of the Economic Part Period with an order frequency of 10 times the order and costs incurred in the amount of Rp. 35,390,310. Method Lot For Lot with the order frequency of 12 times the order and the cost incurred is Rp. 36,720,396. And the Least Total Cost with the order frequency of 10 times the order and the cost incurred is Rp. 35,390,310. In company policy, 12 orders are made at a cost of Rp. 36,720,396. So that the proposed improvement can be given is that the company is expected to use the Wagner-Whitin Algorithm method which has a minimum order frequency and cost.

Abstract

The aim of this research is to determine the causes of delays in the delivery of products to consumers. Big picture mapping will describe the product delivery process flow starting from receiving product delivery orders to the product delivery process carried out by a third party company. Process activity mapping is used to categorize activities into three categories, namely value added, necessary, value added, and non value added. Waste activity identification that occurs in the product delivery process is carried out with the seven waste method, which then causes the waste factors to be analyzed using a fishbone diagram. Lean distribution method is useful for analyzing waste factors as much as possible, so that continuous improvement can be implemented immediately.

Abstract

Penelitian ini bertujuan untuk mengurangi waktu pengiriman sistem distribusi ekspor semen PT. Semen Padang, dengan cara merubah aktivitas yang merupakan pemborosan (waste) menjadi aktivitas yang mendukung nilai tambah bagi perusahaan (VA). Pada penelitian ini menggunakan metode Value stream analysis (VALSAT), yang merupakan alat untuk meminimasi waste (pemborosan) dalam proses aktivitas kerja, khususnya aktivitas pengiriman semen ekspor. Big mapping process dapat memperlihatkan waktu pekerjaan per masing-masing aktivitas pengiriman ekspor, yang diikuti dengan menggunakan metode pertanyaan “why-why” yang berguna untuk mengidentifikasi waste. Dalam penelitian ini VALSAT digunakan untuk menganalisa dan memberi rekomendasi pengurangan waste dengan tipe waiting dari 14% jumlah aktivitas dengan jumlah menit 13 %, menjadi 10% jumlah aktivitas dengan jumlah menit 10%, dan waste dengan tipe transportasi dari 24% jumlah aktivitas dengan jumlah menit 17 %, menjadi 14% jumlah aktivitas dengan jumlah menit 14%. Usulan perbaikan sistem pengiriman distribusi ekspor yang baru menggunakan analisis metode 5W-1H.
