The food industry has been a part of the service sector in Malaysia. The “otak-otak” industry typically catagorised as SMEs which having common limitations of extensively depended on human labour instead of advanced machinery. As the “otak�otak” industries are dealing with a less complicated process, the manual production method is typically selected. Though the production process is not complicated, human limitations might cause production performance and product quality degradation. However, the impact of semi-automation to the production of “otak-otak” remained unclear, thus require the investigation. Through the use of statistical process control, the performance of the manual and semi-automated production process was determined. The integration approached of using ARENA and experimental data was successfully simulates the real production situation. The impact of the implementation of the semi-automated production system was determined and found positively improved the total production performance. This new process has satisfied the minimum requirement of the recommended process capability ratio. Numbers of production issues associated with manual production were determined including the inconsistent utilisation of operator, long value-added time, long product waiting as well as the quality issue of weight inconsistency. The utilization of the operator increased between 10.60 percent to 23.65 percent with the use of a semi-automation system compared to manual operation. The value-added time of semi-automation operation is also shorter than the value-added time of manual operation with the smallest difference of 0.88 seconds and the biggest difference of 1.49 seconds besides, 37.25 percent to 75.80 percent improvement for waiting time. For the aspect of manufactured parts per 1 million, the semi-automated operation has greatly reduced the percentage of product failure in the production of more than 50%. The weight of the “otak-otak” also can be maintain within the range of company specification (25±1 grams).
