Abstract

This study aims to compare the performance of four machine learning algorithms Random Forest (RF), Support Vector Machine (SVM), Logistic Regression (LR), and K-Nearest Neighbors (KNN) in predicting lung cancer severity based on patient medical data. The dataset includes clinical information with the target variable categorized into three severity levels: low, medium, and high. Experiments were conducted using an 80:20 train-test split without feature scaling. The results show that RF achieved 100% accuracy, LR 99%, KNN 82%, and SVM 43%. The superior performance of Random Forest can be attributed to its ensemble of decision trees, which mitigates overfitting in medium-dimensional numerical features, whereas SVM (kernel = RBF, C = 1.0, gamma = "scale") failed to adapt due to the absence of scaling and hyperparameter tuning. Recall, precision, and F1-score further confirm the dominance of RF and LR. This study provides insights into the effectiveness of machine learning algorithms in lung cancer diagnosis and highlights the contribution of a multi-algorithm approach. The findings recommend using RF as the primary model and LR as a complementary control within clinical decision support systems, enabling physicians to make earlier, more personalized treatment decisions and ultimately improve lung cancer patient prognosis.

Abstract

This study aims to predict road damage conditions based on the International Roughness Index (IRI) value using the Roadroid application on class III roads with low traffic volume in Lumajang Regency. This study is important because the road section has not undergone maintenance since 2018, thus potentially experiencing accelerated degradation of pavement performance. IRI data for 2023 was obtained through a field survey using the Android-based Roadroid application and compared with IRI data for 2018 measured using the National Association of Australian State Road Authorities (NAASRA) tool to determine the rate of increase in damage and predict conditions for the next five years. The results showed that the average IRI value in 2023 was in the severely damaged category with a value between 12.5–20.5 m/km. The relationship model between IRI and Average Daily Traffic (ADR) of heavy vehicles produced the equation y = 0.2889x + 1.2993 (R² = 0.935), which indicates a significant effect of heavy vehicle volume on increasing road surface roughness. Predictive simulations indicate that several road segments are expected to reach a state of minor damage within the next 2–4 years, even with overlays. The novelty of this research lies in the integration of historical and survey data with the Roadroid application for predictive modeling of road damage on low-traffic sections as a basis for preventive maintenance planning.

Abstract

Perkembangan pesat teknologi digital menuntut adanya inovasi dalam proses pembelajaran, khususnya pada mata pelajaran Teknologi Informasi dan Komunikasi (TIK) di tingkat Sekolah Menengah Kejuruan (SMK). Salah satu pendekatan pembelajaran yang relevan dengan kebutuhan era digital adalah implementasi Artificial Intelligence (AI) dan pembelajaran berbasis Deep Learning. Penelitian ini bertujuan untuk menganalisis efektivitas implementasi adaptasi pendekatan Artificial Intelligence dan pembelajaran Deep Learning terhadap peningkatan hasil belajar peserta didik pada mata pelajaran TIK di SMK Negeri 1 Pati.Penelitian ini menggunakan metode kuantitatif dengan desain pre-test dan post-test one group design. Sampel penelitian berjumlah 50 peserta didik yang dipilih menggunakan teknik total sampling. Instrumen penelitian berupa tes tertulis yang diberikan sebelum (pre-test) dan sesudah (post-test) penerapan pembelajaran berbasis Artificial Intelligence dan Deep Learning. Data yang diperoleh dianalisis menggunakan statistik deskriptif dan inferensial, meliputi uji normalitas dan uji paired sample t-test untuk mengetahui perbedaan hasil belajar sebelum dan sesudah perlakuan.Hasil penelitian menunjukkan adanya peningkatan signifikan pada nilai rata-rata hasil belajar peserta didik setelah diterapkannya pendekatan Artificial Intelligence dan pembelajaran Deep Learning. Nilai rata-rata post-test lebih tinggi dibandingkan nilai pre-test, serta hasil uji paired sample t-test menunjukkan nilai signifikansi < 0,05, yang berarti terdapat perbedaan yang signifikan antara hasil belajar sebelum dan sesudah perlakuan. Hal ini menunjukkan bahwa integrasi Artificial Intelligence dan Deep Learning dalam pembelajaran TIK mampu meningkatkan pemahaman konsep, keterampilan berpikir kritis, serta minat belajar peserta didik.Kesimpulan dari penelitian ini adalah bahwa implementasi adaptasi pendekatan Artificial Intelligence dan pembelajaran Deep Learning efektif dalam meningkatkan hasil belajar mata pelajaran TIK di SMK Negeri 1 Pati. Penelitian ini diharapkan dapat menjadi referensi bagi pendidik dan institusi pendidikan dalam mengembangkan model pembelajaran inovatif berbasis teknologi cerdas di lingkungan SMK.
