Abstract

This research aimed to develop an optimal expert system by adopting a simplified approach. The methodology integrates an expert judgment approach, limitation inference, and establishing a threshold value. Expert judgment is pivotal in assigning a percentage weight to each rule, facilitating a nuanced evaluation of diagnostic criteria to augment the system's precision. Moreover, incorporating limitation inference strategically constrains the number of user inquiries, streamlining the diagnostic process and enhancing overall efficiency. Additionally, the imposition of a threshold value ensures a more precise early diagnosis by delineating specific criteria for condition identification. This comprehensive approach underscores the paramount importance of user experience and aims to alleviate the burden on individuals seeking a diagnosis. Ultimately, the anticipated outcome of this study is the development of an expert system poised to deliver early diagnoses with heightened efficiency and accuracy. By integrating expert judgment, limitation inference, and threshold values, this research embodies a refined and user-centric paradigm for eye disease diagnosis, promising significant advancements in global eye health.

Abstract

Evaluating student affairs programs remains a persistent challenge in many developing-country education systems, where strong policy intentions often collide with limited resources. This study examines the effectiveness of a student management program at SMP Negeri 1 Kuta Utara using the Context–Input–Process–Product (CIPP) evaluation model, with particular attention to how resource constraints shape overall program performance. Employing an evaluative quantitative design, data were collected from 104 purposively selected stakeholders through questionnaires, structured observations, and document analysis, and analyzed using the Glickman Quadrant. The evaluation reveals a (+ - + +) pattern, indicating that while the program is overall effective and feasible to continue, its effectiveness is structurally constrained by a negative input component. Specifically, inadequate operational funding, insufficient supporting facilities, and an imbalance between the number of student supervisors and students limit program scalability and long-term sustainability. Despite these constraints, positive context alignment, disciplined and well-coordinated implementation processes, and favorable product outcomes such as improved student discipline, enhanced non-academic achievement, and strengthened character development demonstrate the program’s resilience. The study contributes empirical evidence that process quality can partially compensate for weak inputs, but not without risk to sustainability. Practically, the findings recommend targeted investment in student affairs resources, supervisor capacity building, and facility enhancement to prevent erosion of program gains. Theoretically, this study underscores the diagnostic value of the CIPP Glickman integration for identifying hidden structural weaknesses in otherwise “effective” educational programs.
