Abstract
The plantation subsector plays an important role in Indonesia’s economy by providing non-oil export commodities and absorbing a large workforce. However, its production is strongly influenced by climatic factors such as rainfall and air temperature. This study aims to predict the production of large-scale plantations in Indonesia using the Category Boosting algorithm, an advanced version of the Gradient Boosting Decision Tree (GBDT) that effectively handles categorical data without manual encoding. The data were obtained from BPS and BMKG covering the period 2009–2024, including five main commodities: dry rubber, palm oil, coffee, tea, and sugarcane. The research stages include data preprocessing, handling missing values through linear interpolation, feature engineering (seasonal transformation and lag features), and model training under three scenarios: baseline, hyperparameter optimization using Random Search, and forecasting with Walk-Forward validation. The results show that the Category Boosting model demonstrates strong generalization capability, achieving an R2 value above 0.9 in the best scenario even when tested using a strict Walk-Forward validation method. Furthermore, the model underwent a sensitivity analysis and proved capable of projecting production trends up to 2027 under ±10% climate fluctuation scenarios. These findings indicate that Category Boosting is effective in modeling the complex relationship between climate variables and plantation production, providing a reliable foundation for agricultural policy planning and national food security strategies.
