Abstract: Data Mining in Educational System has increased tremendously in the past and still increasing in present era. This study focusses on the academic stand point and the performance of the student is evaluated by various parameters such as Scholastic Features, Demographic Features and Emotional Features are carried out. Various Machine learning methodologies are adopted to extract the masked knowledge from the educational data set provided, which helps in identifying the features giving more impact to the student academic performance and there by knowing the impacting features, helps us to predict deeper insights about student performance in academics. Various Machine learning workflow starting from problem definition to Model Prediction has been carried out in this study. The supervised learning methodology has been adopted and various Feature engineering methods has been adopted to make the ML model appropriate for training and evaluation. It is a prediction problem and various Classification algorithms such as Logistic Regression, Random Forest, SVM, KNN, XGBOOST, Decision Tree modelling has been done to fit the student data appropriately. Keywords: Scholastic, Demographic, Emotional, Logistic Regression, Random Forest, SVM, KNN, XGBOOST, Decision Tree.

Large volume of educational data has led to more challenging in predicting student’s performance. In Malaysia currently, study about the performance of students in Malaysia institutions is very little being addressed. The previous studies are still insufficient to identify what factors contribute to student’s achievements and lack of investigations on exploring pattern of student’s behaviour that affecting their academic performance within Malaysia context. Therefore, predicting student’s academic performance by using decision trees is proposed to improve student’s achievements more effectively. The main objective of this paper is to provide an overview on predicting student’s academic performance using by using data mining techniques. This paper also focuses on identifying the pattern of student’s behaviour and the most important attributes that impact to the student’s achievement. By using educational data mining techniques, the students, lecturers and academic institution are able to have a better understanding on the student’s achievement.

Kinerja siswa sering digunakan sebagai tolok ukur dan keaktifan siswa sering digunakan sebagai kriteria seberapa baik kinerja siswa secara akademik di sekolah. Dimana dalam penelitian ini akan berusaha mencari tahu apakah keaktifan seorang siswa dapat memprediksi kinerja akademiknya. Data yang digunakan adalah dataset pendidikan yang dikumpulkan menggunakan learning management system (LMS), yang merupakan alat pelacak aktivitas pelajar yang terhubung oleh internet. Data ini memiliki variabel numerik dan kategorikal, sehingga diperlukan algoritma yang tepat untuk mengklasifikasikan data secara akurat dan memastikan validitas data. Dalam penelitian ini, algoritma C.50 digunakan untuk menguji data, di mana data dibagi menjadi data pelatihan sebesar 75% dan pengujian data sebesar 25%. Dan hasil dari data yang diuji, akurasi 71,667% diperoleh.
