Abstract

The aim of this research is to find out whether the product produced can provide maximum profits from the sale of cilok and to find out what variables hinder optimum value in the cilok business so mathematical modeling can be created using a simplex method linear program. Cilok is a business that operates in the culinary sector, namely food made from various ingredients, with the main ingredients being tapioca flour and wheat flour. Cilok is round in shape like meatballs, only the basic ingredients are different. Cilok has various filling variants, one of which contains chicken meat and some that don't use any filling. As for the complementary ingredients, namely peanut sauce, soy sauce and sauce, it is a problem that if one of these ingredients is not fulfilled then production in the cilok business will be hampered. From the research results, it is known that the optimal input combination provides a profit of IDR 320,000.00/day.

Abstract

The aim of the research is to analyze the Queuing System at the UMKM  BEANSNOMO COFFE Shop in an effort to increase service efficiency. This research method conducted direct interviews with the owner and used non-probability sample determination. The research results obtained were that the Beansnomo Coffee Shop uses an unlimited population arrival system, with queuing discipline referring to the First-In, First-Out discipline rules. (FIFO) is the most common queue where customers who arrive first (arrive) are served first (leave). With professional treatment, service efficiency can be increased. Based on the results of the respondent table, it can be seen that men are more interested in coffee lovers than women, both young and old. This research can still be developed, so it is recommended for future researchers to use other methods for comparison.

Abstract

The purpose of analyzing the queuing system in the process of customer service in warung lesehan is to evaluate the performance of the service queuing system in Warung Lesehan so as to obtain a decrease in the number of consumer queues. The method of research approach used is descriptive qualitative with data collection techniques through: observation, interviews and documentation with data analysis using Multi ChannelSingle Phase (M/M/1). It can be seen that warung lesehan uses queue model (M/M / 1). The queue structure used is a Single ChannelSingle Phase with only one server and one stage of Service.Usability level of warung lesehan service section = 0.83, the average number in the queue = 4.17/minute, the average number in the system = 5 minutes, the average waiting time in the queue = 0.08/minute, the average waiting time in the system = 0.1 / minute.. It is expected that warung lesehan can further optimize the service performance of each customer, so that customer waiting times are not too long,which makes sales decrease and affect customer arrivals, so queues can still be controlled and there is no buildup of long queues.

Abstract

This study aims to analyze the queuing system and optimize services at Indomaret Padang Bulan Rantauprapat. Using the Multi-Channel Single-Phase queue model, the research identifies service levels and the optimal number of cashiers needed to minimize customer waiting time, especially during peak hours. Data was collected through direct observation over three days, between 12:00 PM and 8:00 PM, with the highest arrival rate observed from 4:00 PM to 5:00 PM. Calculations were conducted using QM for Windows software. The analysis results show an average server utilization rate of 17%, with nearly zero waiting time, indicating sufficient service capacity. These findings demonstrate that with two efficiently operated cashiers, Indomaret can provide optimal services without long queues, making it one of the retail stores with the best service system.

Abstract

The queuing system at BRILink Elvi Juliani on Jalan Sirandorung, Rantauprapat, uses the M/M/1 queuing model to optimize banking services. Data were obtained from observations during one operational day, involving analysis of customer arrivals and service times. The results showed that the average number of customers in the system (LS) was 0.065 customers, while the average number of customers in the queue (Lq) was 0.0004 customers, indicating a very minimal queue. The average customer waiting time in the system (Ws) was recorded at 3 minutes, with an average waiting time in the queue (Wq) of 1.8 minutes. The service busyness level (ρ) was 6.13%, indicating that the service capacity was still sufficient. With high service efficiency, this study provides insight into improving the quality of BRILink services, especially in handling higher customer volumes in the future.
