Publisher : Talenta Publisher

This study aims to show the performance of the ASM method on transportation problem. The transportation problem relates to the distribution of a product from several sources, with limited supply, to several destinations, with a certain demand, in order to obtain the minimum transportation costs. However, the amount of supply and demand cannot always be known with certainty and may change from time to time. In this paper, the coefficient of supply and demand uses fuzzy numbers and uses the ASM method to determine the optimal solution both to minimize costs and maximize profits. The result is that with the ASM method, the balanced transportation problem is always optimal, while the unbalanced transportation problem is not always optimal.

Journal of Mathematics Technology and Education Vol. 1 No. 2 (2022): Journal of Mathematics Technology and Education
Publisher : Talenta Publisher

Dijkstra algorithm is one of the algorithms to determine the shortest path from one vertex to another. In this study, the authors examine the shortest path that fire engines can choose from at the Regional I Fire Unit Post and Region II Fire Unit Post to the most densely populated villages that predict fires, namely Tegal Sari I Village, Sari Rejo Village and Kampung Baru Village. The results obtained are that if a fire occurs in the Tegal Sari I and Sari Rejo Villages, the Regional I Fire Unit which has the closest distance with the shortest route length is 5.16 km and 7.28 km, while if a fire occurs in Kampung Baru Village, the Regional Fire Unit is II which has the closest distance with the shortest route length of 5.32 km.

Publisher : Talenta Publisher

The need for an inventory control system basically arises because of problems faced by the company in the form of excess or shortage of company inventory. The EOQ (Economic Order Quantity) method is one of the inventory control methods used to determine the number of economic orders, namely the number of orders that meet the minimum total inventory cost. The purpose of this study was to determine the optimal amount of cassava raw material inventory at UD Rezeky Baru with the EOQ method and the comparison of the total cost of raw material inventory between costs according to the company and costs according to the EOQ method. Based on the results of calculations using the EOQ method, the optimal number of orders for cassava raw materials in 2019 is 18.722,62 kg. The total cost of raw material inventory using the EOQ method is Rp. 1.497.809,00, while according to the company, it is Rp. 9.467.640,00. The company can save on inventory costs by Rp. 7.969.830,00.

Economic growth in our country comes from various sectors, one of which is the agricultural and plantation sectors. This sector plays an important role in generating a source of foreign exchange for our country after the oil and gas mining sector through its commodity exports. The data used by the author in this final project is secondary data from the Central Bureau of Statistics of North Sumatra regarding oil palm production in Simalungun Regency. Quantitative analysis is used to determine the amount of oil palm production in Simalungun Regency which is predicted in 2020, 2021, and 2022, involving production patterns from 2000 to 2019 Then based on the amount of production data, the data is processed using quantitative time forecasting methods. series, namely Double Exponential Smoothing one parameter from Brown, by looking at the resulting error value, namely the Mean Absoute Percentage Error (MAPE) value. Based on forecasting results, the amount of oil palm production in Simalungun Regency in 2020 is 467,295.15 tons, the amount of oil palm production in Simalungun Regency in 2021 is 501,766.48 tons, in 2022 it is 536,237.81 tons. So the production of palm oil in Simalungun Regency increases from year to year, but there are times when it decreases not so drastically, so it can be concluded that the production of palm oil harvests in Simalungun Regency is increasing.

Publisher : Talenta Publisher

Path analysis is a research method that is mainly used to examine the strength of direct and indirect relationships among various variables. This is in line with one of the objectives of research in social science, namely to determine the existence of a causal relationship. Path analysis can be applied to a social issue, currently the world is worried about the spread of COVID-19. The existence of policies in controlling the spread of COVID-19 disrupts various aspects of life. This study was conducted to determine the factors that cause crime in North Sumatra and to determine the effect of the COVID-19 on the rise of crime rates using the path analysis method. In this study, it was concluded that although there are several exogenous variables that have decreased influence on endogenous variables in 2020, but in this year, which is the pandemic period, the coefficient of determination has the best level.
