Penyakit paru-paru, seperti pneumonia dan kanker paru-paru, menjadi masalah kesehatan global dengan tingkat kematian tinggi, terutama dipengaruhi oleh polusi udara, infeksi, dan kebiasaan merokok. Pencegahan dan deteksi dini sangat penting dalam mengurangi dampaknya. Algoritma yang digunakan dalam penelitian ini meliputi Random Forest, XGBoost, dan Logistic Regression. Tujuannya yaitu untuk membandingkan performa tiga algoritma machine learning dalam mengklasifikasikan penyakit paru-paru menggunakan metrik evaluasi seperti, akurasi, presisi, recall, dan F1-score.  Setelah hyperparameter tuning, XGBoost menunjukkan hasil terbaik dengan akurasi 94,44%, presisi 94,98%, recall 94,44%, dan F1-score 94,41%, menunjukkan keseimbangan optimal antara presisi dan recall. Random Forest juga memberikan hasil yang sebanding dengan XGBoost dengan akurasi dan presisi yang tinggi. Sementara itu, Logistic Regression menunjukkan keterbatasan dalam menangani data yang kompleks, dengan performa yang lebih rendah pada seluruh metrik evaluasi. Penelitian ini menunjukkan bahwa algoritma berbasis pohon keputusan seperti XGBoost dan Random Forest lebih unggul untuk klasifikasi penyakit paru-paru, menjadikannya metode yang lebih andal untuk mendukung deteksi dini penyakit ini.

The aim of this research is to describe the reading interest of fifth-grade students at SD 101776 Sampali, identify the contributing factors, and seek solutions to improve it. The subjects of this study are the fifth-grade students of SD Negeri 101776 Sampali. The research employs a descriptive qualitative method. Data collection techniques include interviews and questionnaires to ensure objective data gathering. Based on observations and interviews with the fifth-grade teacher at SD Negeri 101776 Sampali, supported by distributing questionnaires to the students, it was found that students show little enthusiasm for reading and seldom seek out answers on their own. Instead, they often ask for answers that are already available in the reading materials. Students tend to read only when instructed by the teacher. Even reading textbooks is often done only when there are exams or tests. The low interest in reading among students is also influenced by the type of reading materials available. Typically, students are required to read materials related to their school subjects and are pressured by upcoming exams. This leads to a situation where students view reading as a means to achieve grades rather than for enjoyment.
