Abstract

Queues often occur in public services, one of which is gas station 14.211.203 Jl. D.I Panjaitan No.49 Pematangsiantar, where long queues occur at service facilities, especially in the type of pertalite fuel for motorcycle vehicles. The purpose of this study was to determine the analysis of the queuing system in optimizing services at SPBU 14.211.203 JL. D.I Panjaitan No.49 Pematangsiantar by using a multi-channel single phase queuing model. This type of research is descriptive quantitative. The queuing model applied to this gas station is a single channel single phase model. Based on the results of the study, it is known that with the queuing model applied, it can be said that the level of service at SPBU 13.211.203 is not optimal enough because the busy system utility (p) has a high percentage of the average number of customers waiting in the queue is 3 to 4 customers, The average time spent waiting in the queue is between 1 to 3 minutes, For the average time spent by customers while being served is between 2 to 3 minutes. For this reason, optimization suggestions are given that can be done, namely by using a single phase multi-channel queuing model which uses one service line with two service facilities, then the level of busy service facilities has a smaller percentage of busyness, which is below 50 %, the average level of busyness is below 50 %.

Abstract

This research aims to apply a decision support system using the Analytical Hierarchy Process (AHP) method in selecting the best lecturers at HKBP Nommensen Pematangsiantar University. Selection of the best lecturers is an important process that can affect the quality of education and the reputation of the institution. The AHP method was chosen because of its ability to handle complex decisions involving many criteria. The results of this research show that the AHP method can provide an objective and systematic solution in determining the best lecturers based on educational, research, teaching and ethical criteria. From the results of this research using the AHP method, Dr. Juli Antasari Sinaga., M.Pd as the best lecturer with the sample taken is a permanent lecturer at FMIPA, HKBP Nommensen University, Pematangsiantar. By implementing this decision support system, it is hoped that HKBP Nommensen Pematangsiantar University can increase transparency and accountability in the process of selecting the best lecturers, as well as encourage improvements in the quality of teaching and research in the campus environment.

Abstract

This research aims to determine the inventory control of soybean raw materials applied to the Tahu Tukiran Artomoro Home Industry, to determine the number of orders for economical soybean raw material supplies at the Artomoro Tahu Tukiran Home Industry. The type of research used in this research is descriptive comparative research method. The data processed is in the form of an inventory report on the purchase and use of soybean raw materials at the Tahu Tukiran Artomoro Home Industry in 2023. The data analysis technique used in this research is a tabular approach, and using the Economic Order Quantity (EOQ) method, Reorder Point calculation techniques. (ROP), Safety Stock, Total Inventory Cost. Based on the results of research on the formula approach model using the EOQ method, the economic order quantity for soybean raw materials was obtained, namely 2,335 kg, with an ordering frequency of 14 times, safety stock of 2,715 kg, ROP can be carried out when the soybean raw materials in the warehouse are 123 kg , and total inventory costs of IDR 341,030. The conclusion of this research shows that the application of the Economic Order Quantity (EOQ) method shows a more economical order quantity compared to the method used by the Tahu Tukiran Artomoro Home Industry.

Abstract

Queues are a phenomenon that often occurs in people's lives, especially in the service industry, such as what happens at SPBU 14.211.207 Pematangsiantar where queues start in the morning. This research aims to determine the optimal level of service system for refueling at SPBU 14.211.07 Pematangsiantar. The type of research used in this research is applied research, namely research carried out to obtain information used to solve problems using quantitative methods to determine the optimal level of service systems at gas stations. Data collection was carried out by observing and recording queues that occurred in the morning. The queuing model used is Multiple Channel Single Phase with First In First Out (FIFO) queuing discipline. From the results of calculating the performance of the queuing system at SPBU 14.211.207 Pematangsiantar, adding or more servers will reduce the service busyness level (p), where when using one server the busyness level is 80%, whereas when using two servers the busyness level is 40%.
