Abstract

The Community Service Program (KKN) in Pematang Kasih Village, Pantai Cermin District, focused on the construction of owl houses (RUBUHA) as an environmentally friendly effort to control rice field rats. The background to this activity was the high level of rat infestation that was detrimental to local farmers' rice harvests and the excessive use of chemical pesticides, which had the potential to negatively impact human health and ecosystem balance. The research method used was descriptive qualitative, with data collection techniques through direct observation in agricultural fields, interviews with farmer groups, and documentation of the owl house construction process. The results showed that the village community responded positively to this program because the use of owls as natural predators was proven to be more effective in controlling the rat pest population while reducing dependence on chemical pesticides. In addition, this program also increased public awareness of the importance of ecologically based pest control and preserving biodiversity. With the owl houses built around rice fields, it is hoped that a sustainable agricultural pattern can be created that supports the welfare of farmers while preserving the environment.

Abstract

This study presents the implementation and performance evaluation of a multi-server queueing system model for call center operations using discrete-event simulation combined with Monte Carlo analysis. The objective is to analyze system performance under varying numbers of service agents to identify the optimal configuration that balances service efficiency and customer satisfaction. The model assumes that customer arrivals follow a Poisson distribution, while service times are exponentially distributed to represent realistic call handling behavior. Simulation experiments were conducted over eight-hour operational periods with server counts ranging from one to eight, each replicated 500 times for statistical robustness. Performance indicators such as average waiting time, server utilization, and Service Level Agreement (SLA) compliance were analyzed to measure system efficiency. Results show that increasing the number of servers significantly reduces average waiting time and enhances service level compliance. Configurations with five or more servers achieved average waiting times close to zero and over 99% compliance with the SLA, while maintaining moderate server utilization levels between 70% and 80%. These findings demonstrate that integrating discrete-event simulation with Monte Carlo methods provides an effective and reliable framework for evaluating service system performance, optimizing resource allocation, and supporting decision-making in call center management.
