Abstract

Indonesia sebagai negara kepulauan  terbesar di duniia terdiri dari wilayah daratan dan lautan dengan ribuan pulau kecil yang tersebar di seluruh kawasan perairannya. Akan tetapi pengelolaan ekosistem alam yang buruk selama beberapa tahun terakir berdampak pada kerusakan ekosistem alam yang dari tahun 2017-2021 terjadi deforetasi di pulau kecil mencapai 79% tiap tahunnya. Kerusakan akibat deforestasi tersebut tidak hanya merusak ekosistem alam juga merusak sumber energy yang tidak terbarukan yang disebabkan oleh penambangan dan pembukaan lahan hutan yang melanggar etika lingkungan. Oleh karenanya diterapkan metode critical thinking pada siswa. Berpikir kritis sangat dibutuhkan oleh anak sejak usia dini, utamanya tingkatan sekolah dasar. Dengan berpikir kritis, siswa menjadi lebih tajam dalam memahami permasalahan dan tetpat sasaran dalam menentukan solusi permasalahan yang ditemukan. Adanya smart farming merupakan salah satu pendekatan teknologi yang dapat dilakukan agar kerusakan ekosistem alam dapat dikendalikan. Pengenalan smart farming disampaikan dengan metode computational thinking yang  diikuti oleh 20 peserta yang terdiri dari 17 siswa dan 3 guru pengajar di SD Islam Bintang Juara.

Abstract

This study aims to optimize a machine learning model to predict the corrosion inhibitor effectiveness of N-Heterocyclic compounds.  The main challenge in this modelling is the limited dataset due to the high cost and time required to collect experimental data. To overcome this problem, this research utilizes Kernel Density Estimation (KDE) as a data augmentation technique, generating virtual samples that improve dataset diversity and model predictive performance. The developed dataset includes 11 relevant chemical features such as HOMO, LUMO, and Gap Energy. Linear (MLR, Ridge, Lasso, and ElasticNet) and non-linear (KNR, Random Forest, Gradient Boosting, Adaboost, XGBoost) machine learning models were evaluated based on Root Mean Squared Error (RMSE) and coefficient of determination (R²). The results show that data augmentation using KDE improves prediction accuracy and stability, especially in non-linear models like Random Forest and XGBoost. The application of KDE proved effective in improving the performance of predictive models. It can be recommended as an augmentation method in similar studies that require additional data to improve prediction accuracy.Keywords: Machine Learning, Kernel Density Estimator (KDE), Corrosion Inhibitor, Dataset

Abstract

This research aims to develop a Machine Learning (ML) model that can predict the corrosion inhibitor potential of plant extracts with high accuracy. Corrosion is a serious problem in industry because it can reduce the service life of materials and cause economic losses. This research focuses on the use of green inhibitors, especially plant extracts, which are considered environmentally friendly and have high anticorrosion efficiency. The dataset used includes molecular and physicochemical features of plant extracts. The ML model development process involves data normalization, selection of linear and non-linear ML algorithms, model training with k-fold crossvalidation, and model performance evaluation using regression metrics such as MSE, RMSE, MAE, and R2. Experiments compare various ML algorithms and show that the AdaBoost Regressor (ABR) model exhibits the best prediction performance with the highest R2 value of 0.993 and a low MSE of 0.002. These results provide new insights into the potential of ML models to predict effective corrosion inhibitors from plant extracts. The ABR model had a low prediction error, indicating high accuracy in predicting corrosion inhibition efficiency. In addition, the analysis of important features shows that two features, Conc and LUMO, have a significant influence on the ABR model. This research makes an important contribution to the development of effective prediction methods in the corrosion control industry. The ABR model can serve as a basis for designing more effective and environmentally friendly corrosion inhibitor materials, as well as a reference for other researchers in developing ML models that accurately predict the corrosion inhibition efficiency of plant extracts.
