Abstract

The hybridization between evolutionary genetic algorithm and tabu search has been proposed in this paper to address flow shop scheduling. It accommodates jobs that need to be rearranged and executed on identical machines serially. High agility is required in the manufacturing process, especially for the garment industry to be able to stand facing competitors. The manufacturing related to scheduling to deliver a product as early as possible, the tardiness, and waiting time are also concerned. A Genetic Algorithm was widely used to deal with this; which finds an optimal solution to the problems because it can obtain a more optimal solution. Unfortunately, it is easy to get stuck in optimum local (early convergence is faster). The tabu search algorithm works as a local explorer to better find and exploit the optimum local area, which can be combined with a Genetic Algorithm. This study aims to minimize the three objectives mentioned above to increase production agility. These strategies are evaluated on Taillard benchmark problems to show the significance of the proposed algorithm. The outcomes prove that the hybrid mechanism can boost the solution quality by 2.75% compared to our previous work and can resolve all of Taillard instances better. It has been proven by a 0.28% percentage relative deviation, which shows the error rate is lower and means better.

Abstract

This study aims to develop a fun interactive learning method as an effort to reduce stress due to online learning, especially in Mathematics. The research was conducted on online fifth grade elementary school students. This Powtoon and Adobe Flash-based learning media application can be accessed from cellphones or laptops. The data collection method used in this research is the experimental method. Statistical calculations obtained the results: (1) there was a difference in the mathematical value between before and after being given treatment as indicated by the value of sig = 0.000 (p < 1%), where there was an increase in the mathematical value from an average of 78.53 to 89.41; (2) there is a difference in the level of stress in students between before and after being given treatment as indicated by the value of sig = 0.000 (p < 1%), with the mean value of 47.44 dropping to 39.85 after being given treatment; (3) there is a significant correlation between stress levels and students' Mathematics test scores before treatment, which is indicated by the value of sig = 0.011 (p < 5%). The direction of the correlation is negative with the value of rxy = -0.429; (4) there is a significant correlation between stress levels and students' test scores in post-treatment Mathematics, indicated by the value of sig = 0.038 (p < 5%). The direction of the correlation is negative with the value of rxy = -0.357. Negative correlation means that the higher the stress felt by students, the lower the learning achievement obtained, and vice versa. Evaluation of the learning application was carried out descriptively and satisfactory results were obtained.
