Abstract

Distribution is the delivery of goods from source to destination. Transportinggoods from source to destination requires transportation and distribution costs.Distributing goods requires cost optimization. This research optimizes costsusing a transportation model. Optimization is an activity to get the best resultunder a given situation. The ultimate goal of these activities is to minimize effortor maximize results. The transportation model is a model used to regulate thedistribution of sources that provide the same product to destinations that needit optimally. The transportation model can be completed in two stages, namelythe initial solution using the Vogel's Aproximation Method (VAM) and theoptimum solution using the Stepping Stone method. This study aims tooptimize the cost of distribution of goods from source to destination at UDYosarita. The results of the study using the Vogel's Aproximation Method(VAM) as the initial solution and the Stepping Stone method as the optimumsolution in April 2019 were Rp.4,615,000, in May 2019 Rp.4,810,000, in June2019 Rp. 4,910,000.

Abstract

Rice is a food crop that is needed by the people of Indonesia, because the riceplant as a producer of rice that can be processed as a staple food for thepopulation in Indonesia. Factors considered to have an effect on lowland riceproduction in Langkat Regency are: yearend crop residues, land area, rainyday rainfall, seeds, and fertilizers. In determining the factors that greatlyinfluence the production of lowland rice, it is necessary to use multiple linearregression equations such as using the method backwards. That is, where all Xvariables are regressed with Y variables.

Abstract

Estimates are important tools in effective and efficient planning for predictingfuture events. Identical estimates of the future values of a variable for planningor decision making of a situation to estimate future values. Monte Carlosimulation is a simulation model that involves a series of random and samplingwith a probability distribution that can be known and determined, then thissimulation can be used. In this study, data is taken from the amount of waterusage in PDAM Tirtanadi H.M branch. Yamin, North Sumatra from January2018 to June 2019. Then, the data is processed and analyzed using MonteCarlo Simulation to determine the forecast results in the years that follow. Theresult is an estimated amount of water usage in 2019 and 2020 at PDAMTirtanadi H.M branch. Yamin, North Sumatra is 8,604,556 and 8,592,873. The estimated amount of water use is down from the amount of water use in2018 which reached 8,685,356. The amo

Abstract

UD. Ai Kampung Bilah Tofu Factory, Labuhan Batu Regency is an industry that is engaged in the processing of Tofu. The purpose of this study is to determine the amount of tofu production from forecasting the number of requests for the previous period. Problem with UD. The aim of the Kampung Bilah Tofu Factory is that it has not implemented rules in controlling the supply of raw materials. In the production process, there are often obstacles, namely the use of raw materials and orders that are not appropriate. Optimum planning and inventory of material requirements is carried out using the Material Requirement Planning method. MRP is a method of planning and scheduling better inventory on a product that is produced. In this study the Material Requirement Planning method, the lot sizing technique used is Lot For Lot, Economic Order Quantity, Priode Order Quantity. Based on the calculation results, Material Requirement Planning using the lot sizing technique, namely Lot For Lot, produces a total cost of Rp. 2,640,000 minimum orders for raw materials.
