<![CDATA[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.]]>

<![CDATA[The problem of this research is the low social arithmetic score of class VII students of MTs Negeri 1 North Lampung of 82.10% under the maximum completeness criterion of 70. So a solution to this problem is sought by analyzing student needs. The purpose of the study aims to analyze the needs of students on Android-based M-Learning media. The method used is descriptive exploratory. The research was conducted on March 21, 2022, with 33 class VII students at MTs Negeri 1 Kotabumi as subjects. The research subjects were randomly selected. The data in this study is in the form of an Android-based M-Learning media needs questionnaire. The findings of this study are that students think that social arithmetic is an important but difficult subject to understand. Difficulties in understanding social arithmetic are indicated due to the lack of available learning resources. Furthermore, regarding the learning strategies or techniques used by the teacher in the learning process, students want material. Discussion regarding the analysis of student needs requires learning resources for social arithmetic material in the form of media that can be visualized with moving animation. In addition, it can be packaged and accessed easily on each student's gadget. Android-based M-learning can accommodate all of that, where social arithmetic material is made in an attractive animated form with complete components in it. Components in the form of learning objectives, basic competencies, questions, and exercises. Android-based M-learning is in the form of an application that can then be installed and accessed free of charge by students. The conclusion is that it is necessary to develop Android-based M-Learning media at MTs Negeri 1 Kotabumi]]>

<![CDATA[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]]>

<![CDATA[Let G= (V, E) be a graph order n and an edge labeling ψ: E→{1,2,…,k}. Edge k labeling ψ is to be modular irregular -k labeling if exist a bijective map σ: V→Zn with σ(x)= ∑yϵv ψ(xy)(mod n). The modular irregularity strength of G (ms(G))is a minimum positive integer k such that G have a modular irregular labeling. If the modular irregularity strength is none, then it is defined ms(G) = ∞. Investigating the firecrackers graph (Fn,2), we find irregularity strength of firecrackers graph s(Fn,2), which is also the lower bound for modular irregularity strength, and then we construct a modular irregular labeling and find modular irregularity strength of firecrackers graph ms(Fn,2). The result shows its irregularity strength and modular irregularity strength are equal.]]>

<![CDATA[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.]]>
