Abstract

In the era of Industry 4.0, the need for more attractive and interactive learning instruments has become increasingly evident, especially considering the declining interest in traditional lecture methods among students. The learning media developed in this study aims to leverage multimedia elements such as text, images, animations, and videos to enhance students' understanding and capture their attention towards abstract mathematical concepts. By utilizing the Blogger platform, this media provides flexible access for both teachers and students, offering a more active, enjoyable, and participatory learning experience. This research focuses on developing interactive learning media for Grade 10 students using a Blogger platform for the topic of Systems of Linear Equations in Two Variables. The learning media is designed to meet the criteria of validity, practicality, and effectiveness in enhancing students' learning interest, while also evaluating the levels of these criteria in the media. The Research and Development (R&D) approach was employed in this study, using the ADDIE model which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research instruments included expert validation sheets, student and teacher response questionnaires, model feedback instruments, Pancasila profile instruments, and student learning interest instruments. The trial was conducted in Class X BDP, involving 41 students selected through purposive sampling. Validation results indicate that this learning media has a high level of validity, with an average score of 92.2% from material experts and 83.5% from media experts. The practicality of the media, based on student and teacher responses, model feedback, and the Pancasila profile, showed an average score of 3.4 (good) from students, 3.8 (very good) from teachers, 3.4 (good) from model feedback, and 3.3 (good) from the Pancasila profile. The learning media's effectiveness is evidenced by a 68% improvement in students' learning interest, categorizing it as moderately effective. The study concludes that the interactive learning media based on the Blogger platform for Grade 10 Systems of Linear Equations in Two Variables satisfies the criteria of being valid, practical, and effective for classroom use. Moreover, this media provides significant flexibility for teachers in designing and presenting learning materials, while also offering students the chance to learn independently and interactively.

Abstract

Covid-19 is a dangerous disease that is easily transmitted, both through living media in the form of interactions with infected human, as well as through inanimate objects in the form of surfaces contaminated with the Coronavirus. Various preventive and repressive efforts have been made to prevent the spread of this disease, such as isolating and recovering the infected human. In this study, the authors construct and analyze a new mathematical model in the form of a three-dimensional differential equations system that represent the interactions between subpopulations of coronavirus living on inanimate objects, susceptible human, and infected human within a population. The purpose of this study is to investigate the criteria that must be met in order to create a population free from Covid-19 by considering inanimate objects as a medium for its spread besides living objects. The model solution that represents the number of each subpopulation is non-negative and bounded, so it is in accordance with the biological condition that the number of subpopulations cannot be negative and there is always a limit for its value. The eradication rate of Coronavirus living on inanimate objects, the recovery rate of infected human, and the interaction rate between susceptible human and infected human such that the population is free from Covid-19 for any initial conditions of each subpopulation were investigated in this study through global stability analysis of the disease-free equilibrium point of the model.

Abstract

Pembelajaran yang melibatkan partisipasi aktif dan kemandirian siswa merupakan salah satu faktor penentu efektivitas pembelajaran. Oleh karena itu, guru-guru perlu memiliki kemampuan untuk mengembangkan pembelajaran yang bisa memunculkan sikap aktif dan kemandirian siswa yang salah satunya diwujudkan dalam media pembeljaran yang interaktif. Meskipun demikian, tidak setiap guru di SMP Islam (SMPI) Al Abidin Surakarta memiliki kemampuan yang sama dalam hal pemanfaatan teknologi. Untuk mengatasi permasalah tersebut maka dilakukan kegiatan pengabdian kepada masyarakat di SMPI Al Abidin Surakarta. Para guru dilatih agar mampu mengembangkan media pembelajaran interaktif yang sesuai dengan kebutuhan masing-masing dengan bantuan Lumi Education. Pelatihan dibagi menjadi dua tahap, yaitu pengembangan buku interaktif (Interactive Book) dan permainan dengan peta (Game Map). Hasilnya pelatihan mampu meningkatkan kompetensi guru-guru SMPI Al Abidin dalam membuat media pembelajaran dengan Lumi Education. Para guru mampu merancang, mengembangkan, dan menghasilkan media pembelajaran interaktif yang sesuai dengan kebutuhan pembelajaran.

Abstract

We consider a mathematical model of cervical cancer based on the Natural History of Cervical Cancer. The model is a five dimensional system of the first order of ordinary differential equations that represents the interaction between the free Human Papilloma Virus (HPV) population and four cells sub-populations, i.e., the normal cells, infected cells by HPV, precancerous cells, and cancer cells. We focus our analysis to determine the existence conditions of the nontrivial equilibrium point, the bifurcations, and the sensitivity of the parameters that play important roles in metastasis. Based on the basic reproduction ratio of the system, we found that the infection rate, the new viruses production rate, the free viruses death rate, the infected cells growth rate, and the precancerous cells progression rate play important roles for the cancer spreads in the cellular level. By applying sensitivity and numerical bifurcation analysis, we found that there are some important bifurcations that trigger some irregular behaviours of the system, i.e., fold, Hopf, cusp and Bogdanov-Takens.
