The development of digital technology has increased the use of web-based reservation systems in various sectors, including sports. However, several problems still exist, such as unclear scheduling information, lack of price transparency, and inefficient booking processes that are difficult for users to understand. This study aims to design and evaluate a UI/UX prototype of a padel court reservation system with rule-based dynamic pricing to improve user experience. The method used is Research and Development (R&D), consisting of needs analysis, design using Figma, and usability testing using the System Usability Scale (SUS). The testing involved 39 respondents who had interacted with the system prototype. The results show that the average SUS score is 78.59, which falls into the good and acceptable category. This indicates that the designed system has good usability and provides ease of use in the reservation process. Therefore, the developed prototype can be an alternative solution to improve the quality of digital sports reservation systems.

Because the palm oil harvest cycle affects the seasonal pattern of crude palm oil (CPO) sales, operational planning strategically requires the ability to estimate sales volume. This study uses historical data from January 2020 to December 2025 to forecast monthly CPO sales volume using the multiplicative variation of the Holt-Winters Exponential Smoothing method. 80% of the data is used for training, and the remaining 20% is used for testing. Optimal parameters α=0.3742, β=0.0320, and γ=0.0000 are obtained through modeling. With an MAE value of 2,530.35 tons, an RMSE of 3,036.75 tons, and a MAPE of 12.24%, the model evaluation is classified as good. With a total forecast of 253,127.32 tons, the 12-month forecast results show the maximum peak in September 2026 at 26,743.34 tons and the lowest value in January 2026 at 15,091.27 tons.
