Belajar Teknik Industri - Pengukuran Waktu Standar Kerja (Stopwatch Time Study)

Introduction

This tutorial will guide you through the process of conducting a stopwatch time study to measure standard work times effectively. Understanding this technique is crucial in industrial engineering as it helps optimize processes, improve efficiency, and set realistic performance standards.

Step 1: Prepare for the Time Study

• Identify the Work Process: Select the specific task or process you want to study.
• Set Objectives: Define what you aim to achieve with the time study (e.g., identify bottlenecks, establish standard times).
• Gather Required Tools: Ensure you have a stopwatch, data collection sheets, and possibly a video recording device for analysis.

Step 2: Select Participants

• Choose Operators: Select workers who are familiar with the task for accurate results.
• Consider Variability: If applicable, include multiple operators to account for variations in performance.

Step 3: Conduct the Time Study

• Explain the Process: Brief the participants on the purpose of the study and how it will be conducted.
• Timing: Start the stopwatch as the operator begins the task and stop it as they complete it.
• Record Data: Note the time taken for each cycle of the task. Collect multiple observations (at least 5-10 cycles) for reliability.

Step 4: Analyze the Data

• Calculate Average Time: Sum the recorded times and divide by the number of observations to find the average time per cycle.
• Identify Variations: Look for patterns or outliers in the data that could indicate issues or opportunities for improvement.

Step 5: Establish Standard Time

• Consider Allowances: Factor in allowances for rest, delays, and other interruptions to determine the standard time.
• Document Findings: Create a report summarizing the average times, allowances, and any recommendations for process improvements.

Step 6: Implement Changes

• Share Results: Present your findings to stakeholders and discuss potential process changes based on the analysis.
• Monitor Performance: After implementing changes, continue to monitor the process to ensure improvements are realized.

Conclusion

Conducting a stopwatch time study is an essential skill in industrial engineering that helps in optimizing work processes. By following these steps, you can effectively measure standard work times, identify areas for improvement, and enhance overall efficiency in your operations. Consider repeating the study periodically to ensure ongoing improvements and adapt to any changes in the work process.
