Abstract

This research focuses on analyzing queues at the Teras Coffe cafe using the single channel method. Queues often occur at this cafe due to the high volume of visitors, which causes long waiting times for customers. The aim of this research is to optimize customer waiting time by understanding the existing queuing system. The method used in this research includes collecting primary data through interviews and direct observation in the field. The data obtained includes the time of customer arrival and the duration of service provided by the cashier. By using the single channel method, where there is only one service channel, this research aims to provide a clear picture of the expected waiting time and the number of customers waiting in the queue. The analysis results show that with better arrangements in the service system, waiting times can be minimized. It is hoped that this research can provide useful recommendations for cafe managers in improving service efficiency and customer satisfaction. Thus, this research not only provides insight into queue management, but also contributes to a better customer experience at the Teras Coffe cafe.

Abstract

Currently, many small and medium enterprises are facing big challenges in terms of managing the production and distribution of goods. Breakfast stallBunda Tata is a culinary business that provides various choices of breakfast menu, such as nasi lemak, regular rice and vegetable rice cake. These menus have different preferences every day, depending on customer needs and preferences. Optimizing production in the culinary business world, especially breakfast stalls, is a very important aspect to increase operational efficiency and profitability. One method that is often used to solve production optimization problems is Linear Programming (LP). In this section we will discuss several concepts related to production optimization and the application of Linear Programming in the context of the culinary business. Linear Programming is a mathematical method for solving the problem of allocating limited resources to achieve optimal goals such as maximizing profits or minimizing costs. In solving linear programming problems, a mathematical model is needed. The application of Linear Programming in culinary businesses such as breakfast stalls aims to solve problems related to raw material management, production capacity and profits. Several previous studies have shown that LP can be used effectively in optimizing production in the culinary industry. Bunda Tata's Breakfast Shop wants to maximize profits with QM for Windows, a software used for data analysis and mathematical modeling.
