Abstract

The improvement of productivity is a wise way to fulfill market demand at this competitive era. However, still found facts on field a problem in formulating it, especially to the process with variations. Un-standardized process can lead to ineffective productivity measuring. Wrong measurement could affects to wrong the decision making. This paper was aimed to present real correction to productivity formulation, also the combination of MUDA elimination in an improvement. 5S concept, also emphasized in this effort as other tools in Japanese improvement perspective, KAIZEN. The method used in this research was field study and their related references, including seminar. The result of this research is to describe what exact formulation and elimination of MUDA can be used as the tools to improve productivity at a production line. Through field and literature study, with correct formulation, the productivity of a production line can be effectively and clearly displayed. A Significant improvement can be shown clearly as well.

Abstract

AbstractDetermination of the External Warehouse location has a vital role in the Supply Chain Management system to facilitate the delivery process to consumers who can run smoothly, quickly, and the most optimum distance. The company needs to build a new external warehouse because the current warehouse will be used for new machine installations. Therefore, it was decided to create an alternative external warehouse outside the factory. The purpose of this study is to determine the optimum location of the external warehouse to be made. This study uses the Center of Gravity method to calculate the optimal area that will be considered by the location between the distribution of consumer locations and the number of shipments and also consider the size of the factory that will supply the product. Based on the results of this study, calculations using the Center of Gravity method found that the location of the external warehouse chosen was at (-7.328293, 112.7420916), the settlement area of Jemur Wonosari, Wonocolo, Surabaya City, East Java. By determining the exact location of the external warehouse, the company will benefit from the efficiency of transportation costs.AbstrakPenentuan lokasi gudang eksternal memiliki peran penting dalam sistem Manajemen Rantai Pasokan untuk memfasilitasi proses pengiriman kepada konsumen sehingga proses produk dapat terkirim dengan lancar, cepat dan jarak yang paling optimal. Perusahaan saat ini membutuhkan gudang eksternal karena area gudang yang ada akan digunakan untuk instalasi mesin baru. Oleh karena itu, diputuskan untuk membuat alternatif gudang eksternal di luar pabrik. Tujuan dari penelitian ini adalah untuk menentukan lokasi gudang eksternal yang paling optimal untuk dibuat. Penelitian ini menggunakan metode Center of Gravity untuk menghitung lokasi optimal yang sesuai dengan lokasi antara lokasi konsumen dan jumlah pengiriman dan juga mempertimbangkan lokasi pabrik yang akan memasok produk. Dari hasil penelitian ini, perhitungan menggunakan metode Center of Gravity menemukan bahwa lokasi gudang eksternal yang dipilih berada di (-7.328293, 112.7420916), yaitu daerah Jemur Wonosari, Wonocolo, Kota Surabaya, Jawa Timur. Dengan menentukan lokasi yang tepat dari gudang eksternal, perusahaan akan mendapat manfaat dari efisiensi biaya transportasi.
