The method fuzzy is one part of the fuzzy inference system that is useful for drawing conclusions or the best decision in uncertain problems. Currently, about 200 countries in the world are experiencing the Covid-19 pandemic. Various policies were carried out to overcome this. In addition to the health protocols that are always implemented, the community must also know the conditions of the area where they live so that they can anticipate any activities carried out. The method is used fuzzy to determine the risk zone for the spread of Covid-19 in North Sumatra Province based on 3 variables, namely positive cases, suspected cases, and dead cases. The data used in this study is weekly Covid-19 data from March 2021 to July 2021 for 4 selected areas, namely Medan City, Pematang Siantar City, Simalungun Regency, and Central Tapanuli Regency. All variables are represented using triangular curves and their membership functions are determined. Then the implication function of the min is used to determine the rules used. From the results of the implication function, the composition between all the rules obtained is carried out by taking the maximum rule then that value is used to modify the fuzzy area so that a new membership function is obtained. The method is used centroid to obtain a crisp or the final result is the value of the risk zone. This research also utilizes the Matlab to calculate the results. The results from the use of the Mamdani method will be compared with the real risk zone data so as to produce a 75% average percentage similarity for the data for 4 regions in North Sumatra so it can be concluded that the model made is good enough to determine the risk zone for the spread of Covid-19 in North Sumatra Province.

Distribution routes are generally a problem for every company, including in the public company BULOG Medan Amplas. Distribution to the Medan Amplas BULOG public company, namely having to serve every stall that is far from the warehouse with scattered locations, and limited vehicle capacity. So far, driver considerations in distributing products have only been based on random intuitions of driver and does not consider the efficiency of the route taken. Therefore, this research uses Clarke and Wright Savings algorithm to obtain optimal mileage by taking into account every consumer demand and vehicle capacity. Calculation results using the Clarke and Wright Savings Algorithm obtained the vehicle mileage of 695.08 km with a savings of 11 km or 1.56%.

Analysis of panel data regression is a regression method to determine the relationship between the independent variable and the dependent variable using combined data, namely between cross-section data and time-series data.Analysis of panel data regression can apply to the processing of rice production estimates for an area including the province of North Sumatera. North Sumatera is one of the provinces in Indonesia, at the very of the population focuses on the agricultural sector as the main livelihood in rice being the primary production. Based on data on the development of rice production at the Agriculture Office of North Sumatra Province, the level of rice production in 2019 for North Sumatra Province reached 4,693,563 Ton/Year.Throught Panel Data Regression Analysis with the three approach methods is Common Effect Model (CEM), Fixed Effect Model (FEM) and Random Effect Model (REM) , the best approach method is obtained, namely the Fixed Effect Model (FEM) with the best estimation model is . The coefficient of determination  of 0.950890, which means that the independent variable affects the dependent variable by 95.08% on rice production.Based on the estimation model, the development of rice production in the next 3 years, namely 2020, 2021 and 2022, has changes of around 39.88% (decrease), 10.68% (increase), 9.89% (increase).

The Erlang distribution is a special case of the Gamma distribution with the k shape parameter and the λ rate parameter. In this study, the parameter estimation of the Erlang distribution was carried out using the Maximum Likelihood method. In maximizing the function, an implicit and non-linear form is obtained, then it is solved using the Newton Raphson algorithm. Apart from Newton Raphon, the estimation of parameters was also carried out using the Fisher Scoring algorithm. The Fisher Scoring algorithm is similar to the Newton Raphson algorithm, the difference is that Fisher Scoring uses an matrix information. The result of parameter estimation in Erlang distribution using Newton Raphson algorithm which is applied to outgoing telephone call data that generated by Matlab R2010a software cannot be done simultaneously. Therefore, the parameter assessment is carried out on the k parameter first, then followed by the λ parameter estimation and the parameter and  = 0.6886812 are obtained. Meanwhile, the parameter estimation using the Fisher Scoring algorithm produces an equation that is not different from the Newton Raphson algorithm

Kemiskinan merupakan permasalahan multidimensi yang kompleks dan mencakup berbagai aspek. Akibat kompleksitas yang dimilikinya, penanggulangan kemiskinan memerlukan program yang terintegrasi dan tidak tumpang tindih. Tujuan dari penelitian ini terfokus pada analisis faktor-faktor penyebab kemiskinan di Provinsi Sumatera Utara dengan mempertimbangkan aspek spasial menggunakan metode Geographically Weighted Regression (GWR).  Penelitian ini menggunakan data kemiskinan Provinsi Sumatera Utara pada tahun 2018. Berdasarkan pengujian heterogenitas spasial dan dependensi spasial dapat disimpulkan bahwa kemiskinan dipengaruhi oleh aspek spasial sehingga penelitian ini dapat dianalisis menggunakan metode GWR. Pemodelan dengan menggunakan metode GWR menghasilkan nilai  yang lebih besar  dari regresi global yang mengahasilkan . Kemudian metode GWR menghasilkan  nilai AIC = 171.123 yang lebih kecil dibandingkan dengan model regresi global dengan nilai AIC = 185.909.Hasil analisis menunjukkan karakteristik persentase kemiskinan  mengelompok. Daerah-daerah yang tergolong memiliki persentase tertinggi berada di daerah kepulauan Nias.

Perum Bulog as a State-Owned Enterprise has the main task, which is to conduct a quality and adequate basic food logistics business for the survival of the people. The problem that occurred in Perum Bulog Sub Divre Medan is that the rice supply in Bulog does not consider the demand in the market. Forecasting is an important tool in effective and efficient planning. Therefore, prediction is indispensable for predicting future events. This method essentially uses past data initiated by performing an exponentially decreasing weighting of older observational values or newer values. Brown's double exponential smoothing is a linear model proposed by Brown. This double exponential smoothing method is used when the data indicate a trend. In this study, the terbaik best parameter for forecasting the Number of Rice Sales in Perum Bulog Sub Divre Medan was α = 0.2 with MAPE of 0.27%. And the results of the forecast for Rice Sales at Perum Bulog Sub Divre Medan in 2022 are decreasing every month.
