Abstract

This research aims to determine the right marketing strategy for meatball products and generate optimum profits using Game Theory. The novelty of the research is lies in the object study. The data used in this study is primary data collected by using a questionnaire given to visitors at three Bakso Warungs in Bombana Regency, namely Warung Bakso Solo, Baper, and BRI. The number of samples to be observed is 50 respondents. Then the data that has been collected will be tested for validity and reliability, and then will be processed using the Game Theory method. Based on the results of the analysis obtained the optimal strategy for each meatball stall. The optimal game value obtained shows that the advantage of Warung Bakso Solo in marketing is that product prices are cheaper, but Warung Bakso Solo must use a strategy to improve the cleanliness of the stalls so that sales are optimal. The advantage of Warung Bakso Baper in marketing is the politeness of employees, but Warung Bakso Baper must improve in the strategy of timely delivery of orders. The superiority of Warung Bakso BRI in marketing is product quality, but Warung Bakso BRI must improve its employee politeness strategy

Abstract

The purpose of this study is to find out the queuing model using the structure of the single phase multi-channel queue system in customer service at PT Bank BRI Raha Branch and find out how to complete the queue model on customer service at PT Bank BRI Raha Branch. This research was conducted with direct observation on customer service at Bank BRI Raha Branch. From the data obtained, a steady state test and a Chi-Square kindness test were carried out on arrival patterns and service patterns. Then complete the queuing model using the single phase multi channel queue system structure. The results of the analysis showed that the arrival of customers at Bank BRI Raha Branch was 630 customers with an arrival rate of 2 people per hour and a customer service rate of 5 customers per hour. The queuing system in customer service at Bank BRI Raha Branch follows the queue model which means that the Poisson distributed arrival rate and service time are exponential, the number of channels in the dual system (2 customer service with 1 queue line), the queue discipline used by First Come First Serve (those served are customers who arrive first), the number of incoming customers is not limited or infinite in the queuing system and the population size at the input source is infinite. Busy period opportunities as large as , the average number of customers waiting in the queue is person, the average number of customer in the system is person, the average time spent by a customer waiting is hours, the average time spent in the system including services is hours.

Abstract

Tuberculosis (TBC) is a contagious disease caused by infection with the bacterium Mycobacterium tuberculosis (Mtb), which attacks the lungs. taking into account the laten period of individuals infected with tuberculosis, this study uses the SEIRS model. The total population is grouped into two age groups, group child and group adult . The purpose of this research is to determine SEIRS model of the spread tuberculosis disease with age structure and its completion behavior. The steps in analyzing of the model can be done by determining the equilibrium point, the results are obtained two equilibrium points, namely disease-free equilibrium points and endemic equilibrium points. Determine basic reproduction number and stability analysis at the equilibrium point. Analysis of the stability of the disease-free equilibrium point is carried out to find the stability of the model using linearization around the equilibrium point. The simulation result are disease-free equilibrium point is the asymptotic stable if the basic reproduction number is less than one, and it means that the disease will disappear over time, and the endemic equilibrium point is stable if the basic reproduction number is more than one, meaning there is disease spread in the population.
