Abstract

This research presents the development of a web-based expert system for diagnosing engine faults in Peugeot 406 vehicles, addressing the challenge of limited access to model-specific diagnostic tools particularly in remote or underserved regions where authorized service centers are scarce and the resulting difficulty in early identification of mechanical issues. The system employs a forward-chaining inference method coupled with a depth-first search (DFS) algorithm for rule traversal within a structured knowledge base of 25 engine symptoms and 13 fault types, all formulated through expert interviews and literature review. Through IF THEN production rules, users input observable symptoms via an intuitive, non-technical interface to receive preliminary diagnoses. System testing encompassed simulated case studies covering the full spectrum of defined fault types as well as real-world trials with Peugeot 406 owners in workshop settings, demonstrating over 85% consistency with professional mechanic evaluations. These findings underscore the system’s potential to improve diagnostic efficiency, reduce repair costs, and extend vehicle longevity by enabling timely, data-driven interventions. The implementation of this rule-based expert system thus offers an effective solution for empowering vehicle owners in areas with restricted service access, and future enhancements such as integration of real-time OBD and IoT sensor data, multilingual support, and adaptive machine-learning rule updates are expected to further boost accuracy, flexibility, and user reach.

Abstract

The objective of the research is to design a decision support system for selecting shipping services to the eastern region of Indonesia. The method used is the simple additive weighting (SAW) method, which considers four criteria: Admin Service, Shipping Price, Shipping Speed, and Goods Security. The alternatives for the courier companies used are Jastip Barakati, Jastip Alf, Jastip Duo Amir, and Jastip 42. The research results, based on SAW method calculations for the four existing alternatives, show scores of Jastip Barakati (0.295), Jastip Alf (0.948), Jastip Duo Amir (0.923), and Jastip 42 (0.836), with Jastip Alf being the first choice due to its highest score. As for the criteria, the highest priority is on the item security criterion.Tujuan penelitian adalah untuk merancang sistem pendukung keputusan pemilihan jasa pengiriman barang ke wilayah timur Indonesia. Metode yang digunakan adalah metode  simple additive weighting (SAW) dengan empat kriteria yaitu Layanan Admin, Harga pengiriman, Kecepatan pengiriman dan Keamanan barang. Alternatif perusahaan pengiriman barang yang digunakan yaitu Jastip Barakati, Jastip Alf, Jastip Duo Amir dan Jastip 42. Hasil penelitian berupa hasil perhitungan metode SAW terhadap empat alternatif yang ada menunjukan skor Jastip Barakati (0.295), Jastip Alf (0.948), Jastip Duo Amir (0.923) dan Jastip 42 (0.836), sehingga pilihan pertama dengan skor tertinggi yaitu Jastip Alf. Sedangkan untuk kriterianya, prioritas tertinggi pada kriteria keamanan barang.
