Abstract

Perkembangan teknologi informasi berkembang pesat yang dapat dirasakan sampai saat ini. Namun masih banyak daerah yang belum merasakan kemudahan yang diterima dari dampak teknologi informasi dibidang kesehatan seperti Kecamatan Bantan, Kabupaten Bengkalis, Provinsi Riau. Sebanyak 83% masyarakat Bantan telah mengenal terknologi internet dan dapat mengoprasikanya. Dinas Kesehatan Kabupaten Bengkalis mencatat terdapat 10-15 masyarakat Bantan setiap harinya berobat di Puskesmas dengan gejala penyakit ringan dan bertolak belakang degan kondisi desa yang banyak memiliki tanaman obat herbal. Dalam kaitanya dengan teknologi internet, Informasi kesehatan dan banyaknya tanaman obat herbal, serta SDM dapat dibangun sebuah sistem informasi untuk membantu masyarakat dalam mencari informasi terkait penyakit, tanaman obat serta memanfaatkan tanaman herbal dalam mengobati penyakit ringan. Hasil evaluasi yang dilakukan terdapat 10 responden dari masing-masing desa yang telah mengikuti sosialisasi sebanyak 90% bisa dengan baik menggunakan dan megoprasikan sistem yang dibangun. Dari hasil yang didapatkan dapat ditarik kesimpulan kegiatan yang dilakukan berhasil dan sistem informasi dapat dimanfaatkan dengan baik.

Abstract

Inflation is a crucial macroeconomic indicator that reflects economic stability and influences sectors such as consumption, investment, and policy-making. This study aims to implement and compare three time series forecasting models: Seasonal Autoregressive Integrated Moving Average (SARIMA), Support Vector Regression (SVR), and Long Short-Term Memory (LSTM) to predict inflation in Indonesia. The study utilizes monthly inflation data from Bank Indonesia (2003–2024) and Consumer Price Index (CPI) data from Statistics Indonesia (2003–2019). Model performance is evaluated using Mean Absolute Error (MAE), Mean Squared Error (MSE), and Root Mean Squared Error (RMSE). The results indicate that SVR achieves the best performance in predicting inflation, with MAE of 1.53, MSE of 2.72, and RMSE of 1.64, demonstrating its effectiveness in capturing nonlinear patterns. Meanwhile, SARIMA provides the most accurate predictions for CPI, with MAE of 11.55, MSE of 191.76, and RMSE of 13.84. LSTM shows competitive performance but is less consistent compared to the other models. These findings highlight the importance of selecting appropriate models based on data characteristics to improve forecasting accuracy and support economic decision-making.

Abstract

Education plays an important role in shaping the intellectual and character of the nation's next generation. However, poor student academic performance is a major challenge, especially regarding student retention and dropout risk. This study aims to evaluate the performance of machine learning algorithms, namely K-Nearest Neighbor (K-NN), Light Gradient Boosting Machine (LightGBM), and Extreme Gradient Boosting (XGB), and analyze the effect of dimensionality reduction using Principal Component Analysis (PCA) and feature selection with Recursive Feature Elimination (RFE) on student performance prediction accuracy. The research dataset consists of 395 student samples with demographic, social, and academic attributes. The results show that XGB has the best performance with 98.32% accuracy and can predict all classes with perfect 100% accuracy. LightGBM and K-NN achieved 94.87% and 93.88% accuracy, respectively. The best attributes affecting student performance were found in the “Highly Prioritized” category, including study time, family support, family, and health. Although PCA slightly degraded the model performance, feature selection with RFE significantly improved accuracy. This study concludes that proper algorithm selection and focus on relevant attributes can improve prediction accuracy and efficiency, making an important contribution to the development of more effective education prediction systems.
