The Implementation of Genetic Algorithms for Lecture Scheduling: A Case Study of the Mathematics Study Program at the University of North Sumatra

Introduction

Effective and efficient lecture scheduling is a significant challenge faced by many educational institutions, including the Mathematics Bachelor Study Program at the University of North Sumatra. The complexity of compiling time, space, and lecturers in accordance with various courses and the number of students often leads to scheduling conflicts. This study aims to optimize the lecture schedule to ensure no conflict between lecturers, students, and classrooms, as well as ensuring the appropriate space capacity.

Background

The Mathematics Bachelor Study Program at the University of North Sumatra is one of the largest programs in the university, with a large number of students and a wide range of courses. The program faces significant challenges in scheduling lectures, including:

Space constraints: The university has limited classroom capacity, making it difficult to accommodate all courses and students.
Time constraints: The program has a limited number of time slots available for lectures, making it challenging to schedule all courses without conflicts.
Lecturer availability: The program has a large number of lecturers, but their availability is limited, making it difficult to schedule lectures without conflicts.

Methodology

To address these challenges, this study employed genetic algorithms as a method for optimizing lecture scheduling. Genetic algorithms are a type of search technique inspired by the principles of natural selection. They work by creating a population of possible solutions and then selecting the best individuals to reproduce, creating a new generation of solutions. This process is repeated until a satisfactory solution is found.

Analysis and Explanation

The genetic algorithm used in this study consisted of several steps:

Selection: The algorithm selected the best individuals from the population to reproduce, creating a new generation of solutions.
Crossover: The algorithm combined the genetic information of two parents to create a new offspring.
Mutation: The algorithm introduced random changes to the genetic information of an individual to create a new solution.
Geneepair: The algorithm ensured that each solution still met the predetermined requirements, preventing invalid solutions from emerging.

Results

The results of this study showed that genetic algorithms can produce a more optimal lecture schedule. The scheduling produced:

Adequate rest time: The schedule gave students adequate rest time to move from one class to another, especially for courses with a weight of 3 credits.
Limited classroom capacity: The schedule considered limited classroom capacity, ensuring that the space used was in accordance with the number of students registered.
Improved student satisfaction: The schedule reduced schedule conflicts, increased student satisfaction, and improved the overall teaching and learning process.

Conclusion

This study demonstrates the effectiveness of genetic algorithms in optimizing lecture scheduling. The results show that genetic algorithms can produce a more optimal lecture schedule, reducing schedule conflicts, increasing student satisfaction, and improving the overall teaching and learning process. The study provides a technical solution to the challenges faced by the Mathematics Bachelor Study Program at the University of North Sumatra, improving the quality of student learning experiences.
