Abstract

Climate change and increasing global temperatures have increased the frequency and intensity of forest fires, making fire risk evaluation increasingly important. This study aims to improve the accuracy of predicting forest fuel drought conditions (Drought Code) by using the XGBoost algorithm optimized with RandomizedSearchCV. The research methods include collecting data related to forest fires, preprocessing data to ensure quality and consistency, and using RandomizedSearchCV for XGBoost hyperparameter optimization. The results showed that the optimized XGBoost model resulted in a decrease in Mean Squared Error (MSE) and an increase in R-squared value compared to the default model. The optimized model achieved an MSE of 0.0210 and R2 of 0.9820 on the test data, indicating significantly improved prediction accuracy for forest fuel drought conditions. These findings emphasize the importance of hyperparameter optimization in improving the accuracy of predictive models for forest fire risk assessment.

Abstract

The increase in forest fires poses a significant risk due to its impact on underground dryness, which can cause long-term environmental damage and challenge fire suppression efforts. This research aims to develop a prediction model for underground drought levels in the context of forest fires using machine learning techniques. The methodology used in this research follows the CRISP-DM (Cross-Industry Standard Process for Data Mining) framework, which includes the stages of business understanding, data understanding, data preparation, modeling, evaluation, and deployment. This study analyzes a forest fire dataset, applies encoder labels to transform categorical variables, and uses linear regression and random forest models to predict underground drought levels. The goal is to create a predictive model that can help inform wildfire risk management strategies by anticipating underground drought levels. The results showed that the random forest model achieved higher prediction accuracy than the linear regression, with an R-squared value of 0.97. This suggests that the random forest model is a more robust tool for predicting underground drought levels, providing valuable insights for forest fire management. This research contributes to the understanding of underground drought levels, aiding the development of effective wildfire risk management strategies.

Abstract

Literasi keuangan sangat berkaitan dengan kesejahteraan individu. Pengetahuan keuangan dan ketrampilan dalam mengelola keuangan pribadi sangat penting dalam kehidupan sehari-hari. Kesulitan keuangan bukan hanya dipengaruhi dari rendahnya pendapatan. Kesulitan keuangan juga dapat muncul jika terjadi kesalahan dalam pengelolaan keuangan seperti kesalahan penggunaan hutang dan tidak adanya perencanaan keuangan. Keterbatasan finansial dapat menyebabkan stress, dan rendahnya kepercayaan diri. Literasi keuangan sejak dini bertujuan untuk memberikan edukasi literasi keuangan sejak dini karena pengetahuan dan pengalaman keuangan yang ditanamkan akan melekat dalam diri anak sehingga membentuk karakter dan kebiasaan mengelola keuangan mereka di masa depan sebagai suatu budaya baik, seperti mengenal makna uang, kebiasaan menabung, hingga mendahulukan kebutuhan dari pada keinginan. Metode yang digunakan dalam pengabdian kepada masyarakat ini adalah Participatory Action Research (PAR) Metode ini digunakan dalam mengatasi permasalahan mitra melalui tahapan atau langkah-langkah untuk melaksanakan solusi yang ditawarkan. Melihat hasil kegiatan literasi keuangan yang telah dilaksanakan mulai dari tingkat TK, SD, SMP, SMA dan Masyarakat umum, dapat disimpulkan bahwa kegiatan ini sangat bermanfaat dan memberikan edukasi serta pemahaman mengenai pengelolaan keuangan dengan baik dan bijak, mengingat masih kurangnya literasi keuangan yang dimiliki oleh masyarakat desa.

Abstract

Sentiment analysis plays a vital role in understanding user perspectives, especially in domains such as game reviews where user feedback influences product perception and engagement. This study presents a comparative approach using Gated Recurrent Unit (GRU), hyperparameter-tuned GRU, and Bidirectional GRU models to classify sentiments in a dataset of game reviews. The experiment begins with standard preprocessing and tokenization steps, followed by vectorization and supervised training. Hyperparameter optimization is conducted using Keras Tuner to identify the most effective configuration of embedding dimensions, GRU units, dropout rates, and learning rates. The best model, a Bidirectional GRU with tuned parameters, achieves a validation accuracy of 85.37% and shows superior performance across key metrics such as precision, recall, and F1-score. Despite the relatively small and imbalanced dataset, the Bidirectional GRU model demonstrates robust generalization. This study also highlights future directions, including class balancing techniques and the integration of pretrained word embeddings to further improve model performance.
