Abstract

This study develops a digital system for monitoring and providing price information in traditional markets in Toba Regency. The project addresses the lack of price transparency and difficulties faced by both merchants and consumers in accessing accurate market price data. The system is built using the Waterfall methodology and implements a website and mobile application using Flutter and Golang. Key features include price data input by market managers, administrative supervision by the Department of Cooperatives and Trade (Koperindag), and real-time public access to market prices. The application supports authentication, price management, and category control, and allows the export of reports. Testing was conducted using blackbox and performance methods. Results show that the system improves efficiency, transparency, and accessibility of market price data, supporting digital transformation in local trade.

Abstract

The purpose of this study was to determine whether there is an influence in the application of the STEM-based Read, Answer, Discuss, Explain, and Create (RADEC) learning model assisted by the Autograph application oriented to the mathematical literacy skills of ninth-grade students. The type of research used was Pre-Experimental with one pretest-posttest design. The population in this study was all grade IX. The approach used in this research is Science Technology Engineering and Mathematics (STEM). The research design used was pre-experimental with a one-pretest-posttest design. The sample in the study only used 1 class, namely class IXa, sampling using purposive sampling. Before being given treatment on the learning model and the ability, students were given an initial ability test (pretest), which obtained an average value of 68.23. Then, students will be given treatment in the form of learning by applying the STEM-based Read, Answer, Discuss, Explain, and Create (RADEC) learning model assisted by the Autograph application oriented to students' mathematical literacy skills. After the learning was completed, the final ability test (posttest) was given so that the posttest value was obtained with an average of 85.55. Furthermore, the -test results show that is 11.330 and at significance is 1.68, so that (11.330> 1.68), which means that is rejected and is accepted. Thus, it is obtained that there is an effect of the STEM-based Read, Answer, Discuss, Explain, and Create (RADEC) learning model assisted by the Autograph application oriented to students' mathematical literacy skills in class IXa.

Abstract

The development research aims to produce a mobile learning application for geometry to enhance students' interest in learning mathematics. The product encompasses solid geometry materials for 7th-grade junior high school students. The development process follows the ADDIE model: Analyze, Design, Development, Implementation, and Evaluation. The product underwent testing with 7th-grade students at a junior high school in Yogyakarta. Data collection instruments included a questionnaire on students' interest in learning mathematics, a product validation sheet, teacher and student assessment sheets, and an observation sheet on the feasibility of the learning process. These instruments were utilized to measure the validity, effectiveness, and practicality of the developed product. The research findings indicate that: (1) The developed mobile learning application for geometry is presented using Creative Problem Solving syntax, complemented with features such as liveworksheets, Geogebra, instructional videos, Quizizz, and Google Forms, facilitating the enhancement of mathematical creativity. (2) The developed product is declared valid based on the validation results obtained from two media experts and two content experts, with an average Aiken index reaching 0.94 out of the maximum score of 1, categorizing it as "High." The product is assessed as practical based on teacher assessment at 96.55%, student assessment at 71.28%, and an average learning process implementation percentage of 85.83%. The product is also deemed effective due to a significant increase in the variable of students' interest in learning mathematics. Thus, the developed geometry mobile learning application meets the criteria of validity, practicality, and effectiveness.
