Abstract

Cilegon Mandiri Regional Water Company is a regional government-owned enterprise responsible for providing water supply services to the community, managing water resources, producing clean water, and distributing it to the public. In ensuring the availability of clean water services, PDAM Cilegon Mandiri faces challenges in sustainable water resource management. The objective of this research is to develop a dynamic system model related to the availability of clean water in the Cilegon Mandiri Regional Water Company. The method used in this research is a qualitative-based dynamic system, which is a method used to form the structure, predict behavior, and provide feedback in a system. In modeling a system, dynamic systems require tools to illustrate the interdependencies among system elements, manifested in the form of a Causal Loop Diagram (CLD). The research results identify 14 variables that significantly influence the availability of clean water in PDAM Cilegon Mandiri. There is one reinforcing feedback loop as positive feedback that creates a growth pattern, and two balancing loops as positive feedback related to the improvement of water availability in PDAM Cilegon Mandiri. Although the Causal Loop Diagram approach has helped identify aspects in the clean water availability system, it is recommended to continue with a real simulation model to address real issues in the dynamic system of water availability in PDAM Cilegon Mandiri.

Abstract

The purpose of this study is to assess the level of crowding in service in restaurants in Cilegon City and to propose improvements to the queue system based on the appropriate queue model for the restaurant. The method used is the Discrete Event Simulation (DES) method. The simulation approach allows for an in-depth and direct analysis of the system over a period of time, providing a realistic picture of the situation on the ground.  The data used in this study is primary data, including customer arrival time data and service time (server) data measured using a stopwatch. The results of the study showed that there was a queue with an average of 10 people and a server busyness rate  of 99.32%. This high level of busyness can result in a decrease in customer satisfaction due to long waiting times. Based on the results of the two scenarios tested, namely scenario one with the addition of 1 server and scenario two with the addition of 2 servers, the first scenario involving the addition of one server/cashier was chosen because it succeeded in reducing the number of customers with a busy level of 70.68%.
