Abstract

Examining the production costs employed by PT. Lasting Prosperous Industry is the aim of this study. The research approach used in this study was qualitative research methodology. The population and sample of the study were selected to represent the societal issues that the PT firm deals with. Langgeng Makmur Industri uses field research, including observation, interviews, and documentation, as well as library research. The results of the investigation show that PT. Langgeng Makmur Industri's production cost approach does not fully utilize current theory; yet, because the company levies a 3% reserve fee, the estimation procedure is nevertheless regarded as normal.

Abstract

This study evaluates the performance of the BPJS outpatient registration queue at Royal Hospital Surabaya. Observations show a patient arrival rate (λ) of 270 patients per hour, while the service rate per counter (μ) is only 10.676 patients per hour with two active servers. This imbalance results in a server utilization rate (ρ) of 12.64, leading to an average waiting time of approximately 75 minutes and an average queue length of about 25 patients, both exceeding the hospital’s service standards. Simulation results indicate that increasing the service rate to 20 patients per hour is the most effective intervention for reducing waiting time and improving system stability. The combination of a higher μ with a reduced arrival rate through online registration further shortens queues and creates a more balanced flow of patients. The study concludes that the primary cause of congestion is the structural mismatch between patient arrival intensity and service capacity. These findings provide a data-driven basis for operational strategies aimed at enhancing the efficiency and service quality of BPJS outpatient registration.
