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

There are several factors that cause maternal death, such as bleeding,hypertension, infection, prolonged labor, abortion and others. Maternal deathsrelated to pregnancy, childbirth and the puerperium (42 days after delivery),and the number of deaths per 100,000 live births related to pregnancy ormedical problems (except accidents or incidents). In this study the case ofmaternal mortality using the Bivariate Poisson Regression model which aims todetermine what factors are the main factors in maternal mortality using theBivariate Poisson regression method.

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

Business in the shopping sector is currently experiencing very rapid progressThe phenomenon of the establishment of various supermarkets in big cities is achallenge for the people who keep up the wholesale. The purpose of this studywas to determine and analyze the differences in customer satisfaction levels inshopping in the minimarket. The methods used were questionnaire methodobservation method and documentation method. The highest value is in theclaim that the place is clean and comfortable, the quality of the layout is cleanand orderly, and the employees have a good view of what Alfamart has. Thehighest value is in the claim that the wholesaler has an affordable product pricefor all sections of the society, so that more consumers go to the Wholesaler tobuy goods in larger quantities.
