Abstract

Malaria cases in North Sumatra Province continue to be a public health concern, with regional incidence rates varying. This investigation was designed to assess the variables that contribute to the prevalence of malaria in the province by employing the Zero Inflated Negative Binomial (ZINB) regression model.. The response variable is the number of malaria cases, while the predictor variables are the number of impoverished individuals, population density, percentage of households with proper sanitation, number of healthy homes, and rainfall. For the year 2022, secondary data was acquired from the North Sumatra Provincial Health Office. Excess zero, overdispersion, and multicollinearity tests were conducted prior to the implementation of the ZINB model. The study results indicated that the ZINB model was more suitable than the Poisson and Negative Binomial models. The data indicates that the following variables have a substantial impact on malaria prevalence: an increase in the number of individuals living in poverty (X₁) by 7.8%, an increase in population density (X₂) by 1.8%, an increase in the percentage of households with adequate sanitation facilities (X₃) by 5.9%, and an increase in the percentage of rainfall (X₅) by 3.3%.

Abstract

Rice as a staple food consumed by almost all Indonesia people every day, an adequate supply of rice is needed to meet the needs of the community. Perum Bulog as a government company engaged in food distribution, one of which is rice, plays an important role in the management of rice food stocks. During the rice distribution process, Perum Bulog Sub Divre Medan incurred transportation costs with a large amount. To solve these problems, companies need to use the right methods. One of the methods that can be used for distribution problems is the transportation method. There are two steps to solving transportation problems: the initial solution and the optimal solution. The initial solution uses the Total Opportunity Cost Matrix-Modified Extremum Difference Method (TOCM-MEDM) and the optimal solution with the MODI method. The purpose of this study is to minimize transportation costs at Perum Bulog Sub Divre Medan.  The results of the study show that the use of TOCM-MEDM costs Rp. 151. 103,050 and after the optimization test with MODI it was reduced to Rp. 141,635,000 so that the company could save transportation costs up to 9%, from the initial cost of Rp. 154,847,000 to Rp. 141,635,000. In short, by using the Total Opportunity Cost Matrix-Modified Extremum Difference Method (TOCM-MEDM), the first solution and optimal solution of the MODI Method is the right method to minimize the operational costs of rice distribution in Perum Bulog Sub Divre Medan.
