Abstract

The goal of this article is to ascertain how to maximize sales of internet data packages while keeping the company's marketing budget within reasonable bounds. The technique utilized is linear programming using the Simplex method; this approach's benefit is the ability to compute two or more choice variables, which produces results that are superior to those of the graphical method. Variable Three are utilized in this study: senior marketing (X1), junior marketing (X2), and apprentice marketing (X3). The maximum amount of data package cards that may be sold by the three marketing is 3000. The marketing senior target can sell 1200 packages, whereas the marketing junior target can sell 1200 packages, according to optimization simulation findings using the simplex approach.

Abstract

Good learning media is learning media that is able to provide stimulation to students so as to generate interest in learning. Various types of media, of course students have no difficulty in choosing what media to use, both audio-based, visual-based, and audio-visual-based media. Learning media can be used to generate student learning motivation so that it can improve students' problem-solving abilities. This study aims to conduct a literature review related to effectiveness in learning mathematics at all levels. The research method chosen in this study is SLR (Systematic Literature Review). Data collection was carried out by documenting all articles that had similar research within the last 10 years in this research report. The articles used were 15 national journal articles accredited by Sinta obtained from Google Schoolar. Based on this research, it was found that the use of mathematics learning media can improve students' problem solving abilities, change the mindset and creativity of learning to be more fun. Based on the literature review conducted, learning media can be developed at all levels.

Abstract

This research was motivated by challenges that are often faced by students, namely difficulty understanding the subject matter. This is due to several factors, such as the dominance of learning approaches that involve oral explanations from teachers in class, activities to record or summarize lessons, the material presented in teaching material books is only concise, and the lack of use of learning media-based teaching materials by teachers and schools. The purpose of this study is to create interactive multimedia based on appropriate development procedures, adhering to standards of validity and practicality criteria. Thus, the end goal is to produce interactive multimedia that can be considered appropriate for use in the learning process.  The type and method of research used in this study is research and development (Research and Development-R D) by applying a 4-D model. The development process in this study consists of four stages, namely Define, Design, Development, and Disseminate). The evaluation of product validity is carried out through the participation of three experts, consisting of two validator experts in the media field and one validator expert in the material field. In addition, the product practicality test was carried out involving 16 students from grade VII of SMP Pertiwi 2 Padang. The results of this study showed that the evaluation of media validator experts was declared as "Very Valid", with the average value of the first validator of 4.93 or 98.6% and the second validator with the same average value. Meanwhile, the assessment from expert material validators also received the "Very Valid" category, with an average score of 4.79 or 95.6%. Practicality tests on interactive multimedia show that the product is in the "Very Practical" category, with an average score of 4.73 or 94.6%. In conclusion, the interactive multimedia developed for class VII Informatics subjects has proven to be very valid and practical. Thus, this interactive multimedia is feasible to be used in the learning process.

Abstract

Numerous research endeavors have been undertaken to formulate a flipped classroom learning model to enhance the caliber of education. However, integrating weblogs with the flipped classroom learning model has yet to garner significant scholarly scrutiny. The primary issue pertains to the need for more students' vocabulary acquisition. Consequently, individuals need help with attempting to engage in English language communication. Acquiring proficiency in a foreign language via the Duolingo platform offers a different and unique learning experience. Every educational system must incorporate a comprehensive set of methodological aspects that ensure the efficacy of the learning process. The elements above encompass monitoring progress, motivation, feedback, and vocabulary. The present study employs a quantitative descriptive research design. The research design used in this study is pre-experimental. This study employs a design that incorporates external variables which have the potential to impact the development of the dependent variable. The research utilized the Duolingo application as a tool for student engagement, accompanied by an observation sheet consisting of questions aimed at enhancing teachers' writing proficiency in the learning process. Additionally, post-test sheets were administered to assess the outcomes of the intervention. There is a total of 14 students classified as active, 14 students classified as moderately active, and 12 students classified as less involved. Based on the examination of student activity data, it can be inferred that 70% of student engagement with the flipped classroom approach, employing the Duolingo application for English language acquisition, falls within the active and moderately active classifications.

Abstract

In this research, a triangular patch microstrip antenna with a back-to-back structure technique has been designed to obtain Bidirectional radiation patterns operating at a frequency of ADSB 1090 MHz. The back-to-back structure technique using 2 substrate layers stacked together to form a single microstrip antenna component. As a result, the antenna has 2 patches on both sides of the microstrip, and the feedline is located between the 2 substrate layers. This antenna was designed using simulation software with an FR-4 substrate material. The parameter values obtained from the simulation at a frequency of 1090 MHz are: Return loss -15.4 dB, VSWR 1.4, Bandwidth 17.2 MHz, and Impedance 46.02 Ω.

Abstract

Technology is the result of knowledge development in the field of education. Education is an essential part of improving life and nation-building. Effective education involves actively engaging students and developing their skills while learning in the classroom. Our research aims to analyze learning through the implementation of digital technology in the fourth-grade class at SD Muhammadiyah Karangkajen IV. We used a qualitative descriptive research method, utulizing classroom action research techniques,and conducted interviews with the fourth-grade homeroom teacher. Based on the research conducted, students applied learning theories using visual and audiovisual media during the teaching and learning process. As a result, 75% of the total number of fourth-grade students understood the subject matter and utilized the Power Point media optimally. The implementation of digital technology in SD Muhammadiyah Karangkajen IV can enhance students’ quality and learning development, leading to increased focus, concentration, and motivation due to the engaging learning content presented through Power Point.
