Abstract

Penelitian ini bertujuan untuk menganalisis proses penyebaran hoaks terkait hilangnya story pada akun media sosial Ferry Irwandi, suatu peristiwa yang menimbulkan spekulasi publik dan memicu terbentuknya misinformasi dalam ruang digital. Melalui pendekatan kualitatif deskriptif, penelitian ini mengevaluasi pola interaksi pengguna, alur pembentukan narasi, serta mekanisme komunikasi digital yang berkontribusi terhadap munculnya persepsi keliru. Pengumpulan data dilakukan melalui observasi digital dan analisis konten terhadap percakapan publik, yang kemudian diperkuat dengan kajian literatur mutakhir mengenai literasi digital dan etika profesi teknologi informasi. Hasil penelitian menunjukkan bahwa lemahnya kemampuan verifikasi informasi, kecenderungan bias kognitif, dan pengaruh echo chamber berperan signifikan dalam mempercepat sirkulasi hoaks. Selain itu, minimnya penerapan prinsip etika profesi TI, terutama terkait integritas, akurasi, dan tanggung jawab, turut memperburuk eskalasi misinformasi. Temuan ini menegaskan urgensi penguatan literasi digital dan internalisasi etika profesi TI sebagai strategi mitigatif dalam mencegah disinformasi di media sosial.

Abstract

This study aims to develop a machine learning-based diabetes risk prediction model using the ML.NET framework. The dataset utilized is a balanced-split version of the 2015 BRFSS, consisting of 70,692 respondents and 21 health indicator variables. Two training approaches were applied to analyze model performance: a baseline with default parameters and hyperparameter tuning. The preprocessing stage involved combining variables into feature vectors, Min-Max normalization, and an 80:20 train-test data split. The models were trained using four algorithms: SDCA Logistic Regression, LBFGS Logistic Regression, LightGBM, and FastTree. Evaluation results showed that LightGBM with the hyperparameter tuning approach, delivered the most consistent performance, achieving 75.37% accuracy, 82.86% AUC, 76.22% F1-score, 72.92% precision, and 79.83% recall. Feature analysis confirmed that GenHlth, HighBP, BMI, HighChol, and Age contributed dominantly to diabetes risk, aligning with medical literature regarding metabolic factors. The best-performing LightGBM model was then integrated into a .NET-based prototype application with a Razor Pages web interface. The practical contribution of this research is proof of concept for machine learning integration into e-health systems to support early detection and digital prevention of diabetes complications in the future.
