Abstract

Heart disease is a leading cause of global mortality, with its prevalence increasing annually. This study aims to develop a heart disease prediction model using a Multilayer Perceptron (MLP) combined with the SMOTE-ENN resampling technique to address data imbalance issues. The dataset used was obtained from the UCI Machine Learning Repository and includes patients' clinical and demographic features. The initial dataset consisted of [number of data] records, with an imbalanced class distribution between patients with and without heart disease. After applying SMOTE-ENN, the class distribution became more balanced, allowing the model to learn patterns more effectively. The MLP model was designed with two hidden layers comprising 64 and 32 neurons, respectively, using the ReLU activation function in the hidden layers and a sigmoid function in the output layer. Evaluation results showed that the model achieved an accuracy of 89.47%, precision of 77.78%, recall of 100%, and an F1-score of 87.5%. To validate the effectiveness of SMOTE-ENN, comparisons were made with other methods such as SMOTE and undersampling, as well as baseline models like Logistic Regression and Decision Tree. The results demonstrate that SMOTE-ENN outperforms other techniques in handling class imbalance, leading to better overall model performance.

Abstract

This study aims to determine the role of academic supervision in improving the pedagogical competence of teachers at SMA Plus Al Raihan Sukabumi. Academic supervision is a strategic effort undertaken by the school to ensure the quality of learning runs according to established standards, and to help teachers develop their professional skills, particularly in the pedagogical aspect. Pedagogical competence itself includes teachers' abilities to plan, implement, and evaluate the learning process according to the needs of students. The research method used is a qualitative approach with data collection techniques through interviews, observation, and documentation. Interviews were conducted with the principal, teachers, and supervisors to obtain a comprehensive overview of the implementation of supervision. Observations focused on teacher activities during learning, as well as teacher interactions with supervisors during supervision. Documentation was used to supplement data related to the academic supervision program, lesson implementation plans (RPP), and supervision evaluation notes. The results of the study indicate that academic supervision has a significant contribution in improving the quality of planning, implementation, and evaluation of learning carried out by teachers. Through supervision, teachers are encouraged to be more creative and innovative in developing learning methods and media that are appropriate to student needs. In addition, supervision also provides constructive feedback so that teachers can reflect on their teaching practices and make continuous improvements. Academic supervision also encourages the creation of a collaborative atmosphere between teachers and supervisors, thus creating a working relationship that supports improving the quality of education. Thus, it can be concluded that the implementation of effective academic supervision plays a crucial role in improving the pedagogical competence of teachers at SMA Plus Al Raihan Sukabumi.
