Abstract

The Gorontalo Regency Public Works Department is responsible for a road construction program, in this case, the Public Works Department will conduct project auctions from several existing road projects and there will be one contractor company that will get an auction, where the contractor will produce asphalt in one of the Asphalt companies. Mixing Plant (AMP). The asphalt distribution process of course has routes and distribution costs where this needs to be optimized to get efficient planning in the distribution process, in the project data of the Public Works Department in 2022 there are five road projects and in the Gorontalo Regency area there are five (5) Asphalt Mixing Plants ( AMPs). Distribution is one part of the activities of Supply Chain Management which distributes goods and services from producers to consumers. The idealism of distribution is to distribute or deliver the right amount and type of product at the right time and place at the lowest possible cost to generate maximum profit. The Vehicle Routing Problem (VRP) is related to determining the route for the problem of distributing goods or products involving more than one vehicle with a certain capacity to serve some customers with their respective requests. The results of this study found that the determination of the distribution route of hot mix asphalt with the saving matrix method found that, the Otopade-Liyoto Project (F1) with 1,639 Ton Asphalt Demand, the selected asphalt distributor was (F0-E) PT.PETRA with a distance of 14.4 Kilometers with a total cost of Rp42,508,800. Project (F2) road project Construction of the Buhu - Iloponu Perintis road with an asphalt demand of 609 tons, the selected asphalt distributor is (F0A) PT. Cahaya Nusa Sulutarindo with a distance of 9.6 Kilometers with a Total Cost of Rp 11,712,000. Project (F3) Pilomonu – Pasir Putih road with 763 Ton Asphalt Demand, the selected asphalt distributor is (F0-E) PT.PETRA with a distance of 38.1 Kilometers with a total cost of Rp52,806,600. Project (F4) of Molohu – Langge road with 656 Tons of Asphalt Demand, the selected asphalt distributor is (F0-E) PT.PETRA with a distance of 42.4 kilometers with a total cost of Rp 50,371,200. For the project (F5) of the Helume Bihe - Sukamaju road with an asphalt demand of 1,564 Tons, the selected asphalt distributor is (F0-E) PT.PETRA with a distance of 32.6 Kilometers with a total cost of Rp 92,127,600. Keywords: Distribution, Supply Chain Management, Vihicle Routing Problem, Asphalt Mixing Plant, Hot Mix Asphalt, Direct Shipment, Routes, Cost

Abstract

Coppo Benteng is a company that produces premium quality rice. However, there are problems in the factory activities, namely the rice production process which has several work stations. So it is necessary to analyze in identifying the causes of waste that are described with the help of value stream mapping tools to help the cause of waste in order to create a quality and guaranteed infrastructure. The research method used is the process of analyzing waste in the premium rice production process at CV. Coppo Benteng is carried out by identifying and analyzing activities that do not provide added value and providing suggestions for improvements to eliminate waste. From the results of the analysis carried out on each activity in the premium rice production process at CV. Coppo Benteng Kab. Soppeng resulted in 5 types of waste found, including waste waiting time 20%, waste unnecessary motion 10%, waste defect 5%, waste transportation 5%, and waste processing 10%. The proposed strategy that can be given is to eliminate activities that cause a lot of waste, namely in the waiting time section which must apply the latest technology and improve the infrastructure system.
