Abstract

Lung cancer is a network of cells that grow abnormally in the lungs. Lung cancer has four severity levels, namely stages 1 to 4. If lung cancer is not treated quickly, it is at risk of causing death. This research aimed to combine Synthetic Minority Over-sampling (Smote) and Random Forest methods for lung cancer classification. The method used was a combination of Smote and Random Forest. Smote was used to balance the data, while Random Forest was used to classify lung cancer data. The results showed that the combination of Smote and Random Forest methods obtained an accuracy of 94.1%, sensitivity of 94.5, and specificity of 93.7%. Meanwhile, without Smote, the accuracy is 89.1%, sensitivity is 55%, and specificity is 94.5%. The use of Smote can improve the performance of the Random Forest classification method based on accuracy and sensitivity. There was an increase of 5% in accuracy and a 39% increase in sensitivity.

Abstract

Pemanfaatan teknologi multimedia memegang peranan penting dalam pendidikan. Saat ini, proses pembelajaran musik di TK Mutiara Hati Mataram masih dilakukan secara konvensional menggunakan buku lirik, sehingga memicu kebosanan dan penurunan minat belajar siswa. Penelitian ini bertujuan merancang "Game Edukasi Bernyanyi Lagu Anak-Anak" untuk mengatasi masalah tersebut. Metode pengembangan sistem menggunakan Multimedia Development Life Cycle (MDLC) yang terdiri dari tahapan concept, design, material collecting, assembly, testing, dan distribution. Hasil pengujian menunjukkan bahwa responden sangat setuju aplikasi ini diterapkan sebagai media edukasi. Kesimpulannya, penggunaan aplikasi ini efektif meningkatkan minat belajar anak-anak di TK Mutiara Hati Mataram.
