Abstract

Subject timetabling is an essential component of educational management because it involves allocating subjects, teachers, and instructional time while satisfying multiple scheduling constraints. Manual timetabling practices commonly used in schools often result in scheduling conflicts and require considerable effort when timetable revisions are necessary. Therefore, this study aims to develop and implement an Integer Linear Programming (ILP)-based subject timetabling model using Microsoft Excel Solver for MTs Nurul Ummah. The proposed model was formulated using binary decision variables, an objective function that minimizes scheduling penalties, and a set of constraints representing curriculum requirements, teacher availability, subject allocation, and instructional time. The model was implemented using Microsoft Excel Solver to generate a feasible timetable that satisfies the predefined scheduling constraints. The findings demonstrate that Microsoft Excel Solver provides a practical platform for implementing ILP-based subject timetabling in secondary schools without requiring specialized optimization software.

Abstract

Measuring student discipline is crucial because it helps create an orderly and conducive learning environment and teaches responsibility and self-control. This study aims to develop an effective non-test instrument for measuring student discipline using Exploratory Factor Analysis (EFA) and the Partial Credit Model (PCM) from Item Response Theory (IRT). The instrument was analyzed using EFA, which successfully identified five main factors corresponding to aspects of discipline: self-control, compliance (adherence to rules), concentration ability, strong determination, and responsibility. IRT analysis with the PCM model revealed that the items in the instrument had varying levels of difficulty and discrimination, with nine out of 15 items showing good discriminatory power. This instrument can provide accurate and reliable measurements of student discipline, assisting educators in identifying areas needing improvement and designing appropriate interventions to support character development. This study demonstrates that combining EFA and IRT PCM can produce a valid, reliable instrument with good discriminatory power.
