Abstract
Background: Standard operating procedure (SOP) is a series of business activities to achieve organisational goals, with each activity carried to be recorded and stored in the information system together with its location (e.g., SCM, ERP, LMS, CRM). The activity is known as event data and is stored in a database known as an event log.Objective: Based on the event log, we can calculate the fitness to determine whether the business process SOP is following the actual business process.Methods: This study obtains the event log from a terminal operating system (TOS), which records the dwelling time at the container port. The conformance checking using token-based replay method calculates fitness by comparing the event log with the process model.Results: The findings using the Alpha algorithm resulted in the most traversed traces (a, b, n, o, p). The fitness calculation returns 1.0 were produced, missing, and remaining tokens are replied to each of the other traces.Conclusion: Thus, if the process mining produces a fitness of more than 0.80, this shows that the process model is following the actual business process.

Highlights
In the era of big data, almost all data is stored in the information system
Based on the L* life-cycle methodology used in this study, the process mining using Alpha miner is carried out to produce a process model
The process model is a control flow of activities running on the container port
Summary
In the era of big data, almost all data is stored in the information system. Process mining research is currently growing to control flow and monitoring [1]-[3]. Monitoring is done based on event logs stored in the information system [4]. A container port’s information system records all transaction processes. Dwelling time logs are stored in the information system. Exploring these data using process mining can help measure a port's performance [5]. Objective: Based on the event log, we can calculate the fitness to determine whether the business process SOP is following the actual business process. Methods: This study obtains the event log from a terminal operating system (TOS), which records the dwelling time at the container port. The conformance checking using token-based replay method calculates fitness by comparing the event log with the process model. Conclusion: if the process mining produces a fitness of more than 0.80, this shows that the process model is following the actual business process
