Abstract

Estimating rainfall accurately is crucial for both the community and various institutions involved in managing water resources and preventing disasters. The XGBoost model has demonstrated its effectiveness in predicting rainfall, but it still requires fine-tuning of hyperparameters to enhance its performance. This study seeks to determine the optimal learning rate for rainfall prediction while keeping the max_depth and n_estimator parameters fixed. The hyperparameter optimization process was carried out using a two-step approach: an initial coarse search using RandomizedSearchCV followed by a more detailed fine-tuning using GridSearchCV. The model's foundation relied on historical rainfall data gathered over three months from the Automated Weather Observed System (AWOS) at the Pontianak Meteorological Station, recorded on an hourly basis. To assess the model's performance, several metrics were employed, including accuracy, precision, recall, F1 score, and ROC-AUC. The model demonstrated promising results, with accuracy, precision, recall, and F1 score all reaching 95%, indicating its ability to effectively predict rainfall. However, the ROC-AUC score was somewhat lower at 62%. After conducting the hyperparameter search, the optimal learning rate determined for the model, utilizing the 2040 dataset, was found to be 0.204.

Abstract

The SrCl2 with natural iron sand is the basic material for making Strontontium M-Hexaferrite (SrM) as a generator of electricity in the form of permanent magnets samples which are doped to make the utilization of SrM more effective by adding metal ions that have almost the same size as cobalt (Co) and cupper (Cu) using the coprecipitation method. The synthesis process was carried out in the chemical laboratory of the FKIP, the Highway Engineering Laboratory, the Faculty of Engineering and the advanced Biology Laboratory of the FMIPA UNRAM. In this study, concentration variations and temperature variations were used during the calcination process, namely (x = 0.0; 0.4; 0.8 and 1.0) (T = 800; 1000 and 1100 0C). These variations greatly affect the sample, where the greater the concentration and calcination temperature, the darker the resulting color in the sample and this is in accordance with the purpose of the calcination process, namely the greater the temperature at the time of calcination, the higher the water content in the sample reduced because the solvent in the sample evaporates. In addition to these materials, the solvent used also plays an important role in the process of making samples, namely using 25% HCl to dissolve, 37% NaOH so that the precipitation process is faster and distilled water as a neutralizer.
