Abstract

This study investigated the corrosion inhibition potential of ionic liquid compounds using a QSPR-based machine learning predictive model combined with DFT calculations. The Gradient Boosting (GB) model was identified as the most effective predictor, demonstrating excellent accuracy with a high R² value of 0.98. Additionally, the model exhibited low RMSE (0.95), MAE (0.84), and MAD (0.94) values. The predicted corrosion inhibition efficiencies (CIE) for three new ionic liquid compounds (IL1, IL2, and IL3) were 88.95, 90.82, and 93.16, respectively, which aligned well with experimental data. By integrating DFT simulations into the data updating process, facilitated by machine learning, the approach proved invaluable for identifying new corrosion inhibitors. This work highlighted the continuous refinement of data related to the corrosion inhibition effects of ionic liquid compounds.

Abstract

Proses penyampaian ilmu pengetahuan salah satunya ada di proes pendidikan dasar yang diterapkan pada proses persekolahan. Salah satu yang mendukung untuk mengembangkan pengetahuan adalah menggunakan konsep Computational Thinking (CT) melalui soal-soal Bebras. Pengetahuan mengenai soal bebras dapat membantu guru dan siswa dalam mengembangkan kemampuan dan kreatifitas dalam berpikir kritis dan melakukukan analisis dalam menyelesaikan masalah. Metode pembelajaran berbasis simulasi yang digunakan dalam proses pelatihan yang diharapkan dapat membantu guru dan siswa dalam memvisualisasikan konsep secara lebih baik dan jelas serta diharapkan pula siswa mendapatkan keterampilan yang baru dengan tidak takut jika melakukan kesalahan.
