Abstract

The purpose of this study was to use an ordinal logistic regression model to analyze socioeconomic factors in children's educational institutions in Tuntungan village. This study collected primary data on family economic status (high, medium and low categories) and social environment (very supportive, supportive, less supportive and non-supportive categories) from 100 respondents. The results of the analysis show that families' economic status significantly affects the quality of education facilities for their children, with families with higher economic status having better access compared to families with medium and low economic status. In addition, although not as large as economic position, socio-ecological status is also important. The resulting logit model shows that economic variables have a greater influence on the quality of children's educational institutions compared to social variables. This study emphasizes the importance of improving the local economy to expand access to high-quality education

Abstract

The queuing system in the Customer Service (CS) department of Bank Sumut KCP USU was studied using the Multi Channel Single Phase (M/M/s) model. The purpose of this analysis was to evaluate service effectiveness and identify the best queueing arrangement to reduce customer waiting time. Direct observation of customer arrivals and service times over two working weeks produced primary data. The system was in a stable state. The results of the Chi-Square distribution test showed that service time followed an exponential distribution and customer arrivals followed a Poisson distribution. With one customer service officer, the service level increased to 6–8 customers per hour, compared to the usual customer arrival rate of 3–5 people per hour. The system is still stable, according to the agent workload level of 0.44, but efficiency decreases with an average waiting time of 12.5 minutes during peak hours (09:00–11:00). According to the simulation, waiting time can be reduced to less than one minute and the overall service duration to around nine minutes by adding one CS, making a total of two agents. Therefore, it is recommended that Bank Sumut KCP USU employ two active customer service agents during peak hours to improve customer satisfaction and service efficiency
