Capacity utilisation is one of the most important aspect in business. Low capacity utilisation means that the company does not use its resources efficiently to generate profit. In service industry, there are many researches that suggest the capacity utilisation has a direct contribution towards the company profit. To make an accurate capacity planning, it must be based on several factors, and forecasting is amongst the most important aspect. PT. Perigi Raja Terpadu is a Tier Two of Import Temporary Warehouse company that operates at the Soekarno Hatta International Airport in Jakarta, Indonesia. Currently, they have low peak capacity utilisation, which rated at 28.91%. Company does not have a projection on how or when should they achieve such an adequate capacity utilisation. As of now, they only having rough-monthly forecast which is not suitable to predict capacity utilisation. With these two indicators, they need a new capacity planning to achieve efficiency, which will be based on the most accurate forecasting method. To develop the compliant forecasting method for PT Perigi Raja Terpadu, this research uses Time Series Analysis. Every method is related to the real demand and thus the method most appropriate for PT Perigi Raja Terpadu will be chosen based on the lowest error. Upon deciding the most effective method of forecasting, this work also allows the designing of new capacity planning for the company which has higher Earning Before Tax (EBT) compared to current capacity planning. The results of the analysis conclude the most effective predictive approach with PT. Perigi Raja Terpadu is the Winter Method since it has the smallest error among others. By using this model, the measure accuracy is as follows: MAPE = 29%, MAD = 1897, MSD = 8217194. Proposed capacity planning will be focused on achieving 80% of peak capacity utilisation, where it has the highest performance of EBT, among higher or lower capacity utilisation. By applying proposed capacity planning, PT. Perigi Raja Terpadu can further improve their EBT by Rp 1.003.507.894, or 15.9% compared to the current capacity planning for the next two years.
