Rule-Based Expert System Model with Backward Chaining Algorithm for Symptom-Based Skin Disease Diagnosis
Get PDFA rule-based expert system was a computational model designed to emulate expert decision-making using a knowledge base and inference algorithms. This research developed a rule-based expert system model with a backward chaining algorithm to diagnose skin diseases based on clinical symptoms. Backward chaining, a goal-driven inference method, started with a disease hypothesis (e.g., psoriasis) and verified related symptoms (e.g., kemerahan, sisik keperakan), enabling efficient differentiation of skin diseases with overlapping symptoms, such as dermatitis, psoriasis, and scabies. The model provided advantages in handling uncertainty, produced accurate diagnoses, and supporting interactive symptom verification. Developed using a knowledge base from credible sources like WHO and AAD, the model was intended to assist in clinical decision-making. The results showed that the backward chaining algorithm effectively improved the accuracy and efficiency of diagnosing skin diseases based on patient-reported symptom

Optimising User Interface (UI) and User Experience (UX) on E-Commerce Platforms to Improve Customer Retention
Get PDFFierce competition in the world of e-commerce requires platforms not only to attract new customers but also to retain existing ones in a highly dynamic digital market. Customer retention, defined as a business’s ability to maintain customer loyalty over a specific period of time, has become a vital metric for long-term business sustainability. As consumers are increasingly exposed to multiple shopping alternatives, e-commerce platforms must ensure that their digital environment remains engaging, efficient, and user-friendly. This study highlights the crucial role of User Interface (UI) and User Experience (UX) as key determinants that influence customer behaviour and significantly contribute to improving retention rates. Using a combination of literature review and case study methodology, this journal identifies several essential UI/UX elements that directly impact user satisfaction. These elements include clean and visually appealing interface design, intuitive and predictable navigation paths, fast loading speed, and a seamless, simplified checkout process. Each of these components plays a strategic role in reducing user frustration, increasing convenience, and fostering trust in the platform.
