Abstract

This study discusses the performance of the queuing system in optimizing service at motorcycle service. This research was conducted at PT. Hasjrat Abadi-Yamaha Gorontalo, the research was conducted by taking primary data for 27 days at 08.00 - 12.00. The variables used are customer arrival time data and customer service time. The results showed that the queuing system at the motorcycle service station is the arrival time distribution, namely the Poisson distribution, while the service time distribution is the general distribution. So the queuing system at the motorcycle service center follows the model (M/G/6)(GD∞/∞)From the calculation of the performance tables of several different servers, it has been found that the performance of the queuing system contained in the motorbike service is optimal using 5 servers. Testing the distribution of arrival time and customer service is carried out using SPSS.25 software.

Abstract

Petri net is one model representing transitions and places connected by arrows. Max Plus Algebra is an algebraic structure in which all sets of real numbers  are equipped with max (maximum) and (addition). This research created a Petri net model of the customer service system for Bank BRI and a Max Plus Algebra model related to time to minimize service time at Bank BRI. The result is periodic time or characteristic values and vector characteristics where the values and are . The value of this vector's characteristics becomes a periodic time, which only takes 2 days 3 hours during working hours to disburse money after the client's arrival.

Abstract

This study aims to apply Petri Net for queuing services for gas stations in the city of Gorontalo. The subject that became the focus of the research was the Jalan Jendral Sudirman gas station. The results obtained in this application are 11 places and 11 transitions, a matrix representation of the model, and the convertibility tree model.

Abstract

This research aims to determine the effect of the think pair share type cooperative learning model assisted by educational videos on student learning outcomes in relation and function material. The research was carried out in SMP Negeri 1 Suwawa in the alternate semester of the 2022/2023 academic year. The population in this study was all class VIII, totaling 83 people. The sample used was 20 students in the experimental class and 20 students in the control class. The research results show a significant difference in the average learning outcomes of students who study using the think pair share cooperative learning model, which is higher than the direct learning model.

Abstract

This study aims to determine the factors that most influence the rate of recovery of pulmonary tuberculosis patients using the Cox Proportional Hazard model. In the case of the cure rate of pulmonary tuberculosis patients, not all independent variables meet the proportional hazard assumption, so the stratified cox regression model is used. The stratified cox regression model used is the stratified cox model with interaction and without interaction involving pulmonary tuberculosis patients in one of the Gorontalo Hospitals. The results showed that the variables of shortness of breath, previous pulmonary tuberculosis patients, and smoking habits were the most significant factors affecting the recovery rate of pulmonary tuberculosis patients.
