Abstract

Penelitian ini mengkaji prediksi suhu permukaan laut (SPL) di Taman Laut Bunaken yang diproyeksikan meningkat secara signifikan, dengan dampak yang berpotensi besar bagi sektor pariwisata dan ekonomi. Metode yang digunakan adalah kuantitatif deskriptif dengan model Neuralprophet, yang merupakan pengembangan dari Facebook Prophet dan menunjukkan peningkatan kinerja prediksi. Tujuan penelitian ini adalah memprediksi SPL hingga tahun 2032, serta mengidentifikasi konfigurasi hyperparameter Neuralprophet yang memberikan performa optimal. Model Neuralprophet dilatih menggunakan 80% data, menghasilkan nilai MAE training sebesar 0.204115, RMSE training sebesar 0.258052, dan Loss training sebesar 0.004066. Pada tahap pengujian dengan 20% sisa data, model menghasilkan MAE validasi sebesar 0.216127, RMSE validasi sebesar 0.27317, dan Loss validasi sebesar 0.003463. Hasil prediksi menunjukkan adanya peningkatan rata-rata SPL sebesar 0.003815°C per bulan selama 120 bulan, dengan estimasi total peningkatan SPL sebesar 0.4578°C pada tahun 2032.

Abstract

PM10 are airborne particulates that have a diameter of ≤10 μm. The potential hazards of PM10 particulates are an issue that is being intensified by many researchers. This research utilizes PyCaret, a library to accelerate the process of modeling and experimentation in the field of machine learning (ML) and data science. This research compares the performance of three decision tree-based models Extra Trees, Random Forest, and XGBoost in predicting PM10 particulate levels, presenting data and visualizations for each models predictions. The data used is ISPU data at five air quality monitoring stations in Jakarta, with the main dataset of PM10 in 2021. The forecast results show an increasing graph pattern, with higher fluctuations in XGBoost. The Extra Trees model produces the best performance, with MASE 0.8808, RMSSE 0.8113, MAE 12.6173, RMSE 14.7436, MAPE 0.2433, SMAPE 0.207, and R² -1.2013.
