Abstract
ABSTRAK 
Depresi merupakan salah satu gangguan kesehatan mental yang sering tidak terdeteksi 
akibat keterbatasan akses terhadap layanan psikolog profesional. Penelitian ini bertujuan 
untuk mengembangkan sistem pakar berbasis web guna membantu deteksi awal gejala 
depresi pada mahasiswa berusia 18–24 tahun. Sistem ini menggabungkan metode Forward 
Chaining untuk penarikan kesimpulan berbasis aturan dengan metode Certainty Factor 
(CF) dalam menghitung tingkat keyakinan terhadap hasil diagnosa. Pernyataan dalam 
sistem didasarkan pada kuesioner MINI ICD-10 sebagai acuan diagnostik. Dengan 
menggabungkan kedua metode ini, sistem mampu mengidentifikasi potensi enam jenis 
gangguan mental: episode depresif, distimia, episode manik, agorafobia, gangguan panik, 
dan fobia sosial. Pengujian sistem menggunakan metode white-box dan black-box 
menunjukkan bahwa sistem berfungsi dengan baik. Meskipun sistem ini dapat memberikan 
gambaran awal kondisi psikologis, hasilnya tidak dimaksudkan sebagai pengganti 
diagnosis profesional. Sistem ini dirancang untuk meningkatkan kesadaran dan menjadi 
panduan awal menuju penanganan kesehatan mental yang lebih tepat.

ABSTRACT 
Depression is a common mental health condition that often goes undiagnosed due to 
limited access to professional psychological services. This research aims to develop a 
web-based expert system to assist in the early detection of depression symptoms in 
university students aged 18–24. The system integrates the Forward Chaining method for 
rule-based inference with the Certainty Factor (CF) technique to calculate the confidence 
level of each diagnosis. The MINI ICD-10 questionnaire serves as the foundation for 
diagnostic criteria. By combining these methods, the system can determine the potential 
presence of six types of mental disorders: depressive episodes, dysthymia, manic episodes, 
agoraphobia, panic disorders, and social phobia. System testing using both white-box and 
black-box methods confirms its functional accuracy. Although this tool provides an initial 
assessment of mental health conditions, it is not a replacement for professional diagnosis. 
Instead, it aims to increase awareness and serve as a preliminary guide toward seeking 
appropriate mental health support.
