Abstract

Panasab glass is one type of glass that can absorb some of the heart's heat so that the temperature in the room is more comfortable. One of the national glass companies that produce hot glass monitors the silvering coating process. The silvering method is considered less effective because it is expensive. Therefore, in this paper, the process of controlling the quality of hot glass is carried out on the quality characteristics of the left and right CD edge distortion, which is the length of the roll marks on the right and left sides of the net glass that affect the presence or absence of distortion in the visual check results. The two quality characteristics correlate with each other. Therefore, quality control is carried out using a Multivariate Exponentially Weighted Moving Average (MEWMA) control chart to monitor process variability and averages. MEWMA control chart statistics are affected by the weighting value . The quality characteristic data of panasab glass is divided into phase 1 and phase 2. Phase 1 is used to obtain an in-control parameter estimate (IC) which is then used for monitoring phase 2. Quality monitoring in phase 1, the process has been statistically controlled after iterations have been carried out. By using =0.4. Meanwhile, phase 2, based on the MEWMA control chart, shows that the producton procrss of panasab glass production has not been controlled statistically. Based on process capability analysis, the results obtained that the level of precision and accuracy of the quality of panasab glass products is still low. So it can be concluded that the production process of panasav glass is not yet capable.

Abstract

The Role of Student Team Heroic Leadership Strategy: Mathematical Communication of Middle-School Students. Objectives: In this article, we focus on how to improve students’ mathematical communication in building effective group discussions using the student team's heroic leadership strategy. Methods: This type of research is Classroom Action Research, which was held in 2 cycles. The research subjects were 16 seventh-grade students (six boys and ten girls). Findings: The findings indicated that by implementing the Student Team Heroic Leadership learning strategy, students’ mathematical communication improved significantly. This finding is confirmed by the increase in the average score on students’ communication tests from 76% in cycle I to 96% in cycle II. The completeness criteria of the students’ mathematical communication exam results also progressed from the first to the second cycle. Other data indicate that students concealed information they did not comprehend during the learning process, making it harder for the teacher to assess their comprehension of the mathematical concepts provided. Conclusion: The study’s findings indicate that after using the Student Team Heroic Leadership learning strategy, students’ mathematics communication skills improved dramatically. As suggested, additional research should be able to examine ways to boost students’ self-confidence, particularly while displaying confusion when doing mathematical tasks provided by the teacher.

Abstract

The interaction between two populations that are prey and predator can be described in a prey-predator model. In fact, in the interaction of prey and predators it can occur that when the density of prey is low, the effect of predation is also low, but if the size of the prey population increases, predation will be more intense which is stated in the Holling III Type response function model. In addition, it can also be found in an environment where there are populations of sick predator that result in death from the disease. This study aims to analyze the stability of the prey-predator model with the Holling III Type response function which consists of three subpopulations namely prey, healthy predator and sick predator. The analysis was carried out using the linearization method and then the type of stability was determined based on the characteristic eigenvalues obtained using the Routh-Hurwitz criteria. From this research it was found that population extinction is not possible while prey exists, extinction of diseased predator and populations exist is still possible if the required conditions are satisfy. Numerical simulations show that an increased harvesting rate in healthy predator populations results in a decrease in healthy predator populations, an increase in prey populations and a decrease in diseased predator populations. Meanwhile, a reduced harvesting rate for sick predator populations does not have a significant effect on the number of diseased predator populations, but results in an increase in the number of healthy predator populations and a decrease in prey populations
