Abstract

Here we examine the dynamic model of the spread of Dengue Hemorrhagic Fever (DHF) assuming a constant number of host and vector populations. In this paper, the model is reduced from a three-dimensional system to a two-dimensional system so that the dynamic behavior can be analyzed in the R2 plane. In the two-dimensional model, if the threshold parameter R > 1, the endemic state becomes globally asymptotically stable. During the analysis of its dynamic behavior, a trapping region is found which contains a heteroclinic orbit connecting the slowing point, namely the origin and the endemic point. By using heteroclinic orbits, it can be estimated the time period required from a state to reach a certain state.

Abstract

A healthy Internet is one of the basic needs of the use of digital technology in various fields, especially in the world of education. Since SMAN I is one of the service partners and is also very close to the center of agriculture and tourism, Community is carried out by the Information System Study Program, Universitas Methodist Indonesia as a form of implementing the Tri Dharma of Higher Education. Its purpose and benefits are to share and contribute ideas and transfer knowledge and technology. This service activity was carried out for a day, with the material including explanations about Internet Sehat (Healthy Internet) and Internet Cakap. This topic is very much needed in the education community to be able to use the internet intelligently, creatively, and productively.

Abstract

At SMPN 2 Pancur Batu, there is currently no adequate facility to manage and facilitate the delivery of learning information to support students' learning activities, including the provision of learning materials and assignments and the submission of assignments online. The school still primarily applies face-to-face learning methods. When teachers are unable to attend classes, lessons may be canceled or limited to assigning tasks without direct supervision. Similarly, students who are absent cannot participate in classroom learning as usual. Therefore, SMPN 2 Pancur Batu requires a web-based mobile E-Learning system that can be accessed anytime and anywhere to support the teaching and learning process without requiring face-to-face interaction. The system testing results indicate that the E-Learning application facilitates students and teachers in conducting online teaching and learning activities. Teachers can deliver learning materials, assignments, and quizzes efficiently, while students can access them online. The system also provides grade feedback through parents' email, allowing parents to receive notifications regarding students' learning outcomes. Validation results from five teachers based on seven assessment items obtained a score of 72.5%, categorized as "Good." Meanwhile, questionnaire results from 25 students based on 18 items obtained a score of 76.5%, categorized as "Good." The media expert evaluation achieved a score of 89.3%, categorized as "Very Good." These results indicate that the developed E-Learning system is suitable for supporting learning activities at SMPN 2 Pancur Batu.
