Abstract

Simulation plays a crucial role in increasing customer satisfaction and strengthening long-term relationships. Focusing on speed and convenience of service, as well as efficient management is essential in business strategy. Understanding customer characteristics and applying technology supports service efficiency. The method in this research is observation, where the results of the observation become the basis for analysis and decision making. This research aims to compare simulation methods between existing models using Arena and alternatives using Flexim. Based on the results of the t-test, with the hypothesis of testing the significance of the differences between the two models. Based on t-alpha analysis and t-test statistical tests on data processing using the data analysis feature in Ms. Excel, it was found that the critical limit for a 2-sided acceptance chart is +-0.9861. The t-test result of 0.9814 is in the acceptance area, supporting the statistical sustainability of the model with the observation results. Thus, it can be concluded that the data can accept Ho and the system is considered valid. The recapitulation shows that service 3 in Alternative 1 has the highest sales, but with a longer stay time. Alternative 1 on service 1 has the fastest stay time. The existing model has an even distribution without distinguishing the number of goods purchased. The result of using the existing model with the arena is replication in the range 60-769 seconds with the number of queues in the range 77-409 seconds. Meanwhile, using flexsim on the existing model gets a queue time on 10 replication models of around 66-70 seconds. Based on the results of observation data, it shows that the queue time range is 112-115 seconds. Therefore, flexsim data is also considered invalid because the time span is quite different. So, it can be concluded that the existing service and queue models are good.

Abstract

The importance of occupational safety and health (K3) in industry, especially in Indonesia which is experiencing rapid growth in various sectors, including industrial chemistry. The use of chemicals and modern equipment in the industrial chemical production process increases the potential for danger to occupational health and safety and the environment. Indoclean Dynamic Company is a chemical industry company in Indonesia, using risk analysis, various potential hazards were identified, such as dust, inadequate ventilation, use of equipment without personal protection (PPE), and cramped work space conditions. Risk assessment is carried out to determine the level of risk which includes the possibility of occurrence and the level of severity that can be caused. The assessment results show that several processes have high risks, especially related to the use of PPE and room lighting. Suggested prevention suggestions include providing appropriate PPE, improving room lighting, and warning signs of dangerous chemicals. In conclusion, risk prevention and control efforts need to be improved to ensure a safe and comfortable work environment for PT.Dynamic Indoclean employees.
