Abstract

This study explores the development of Kodular-based learning media to enhance the quality of informatics education. The study addresses the need of more engaging learning media and better technology integration in teaching using a Research and Development (R&D) design and a modified 3D model out of the 4D development model, including defining, designing, and developing. The research involved 20 students from SMK Negeri 1 Bangkinang, employing all stages of the development model: need analysis, media development, validation, and trial to students. The defining stage revealed inappropriate teaching method uses, leading students to have less motivation in learning. Consequently, this research developed learning media, focusing on number systems material (decimal, binary, octal, hexadecimal), organized in a visually appealing and concise format. In the designing phase, the Kodular media was developed to be user-friendly, featuring quizzes, exercises, and interactive modules. Validation results showed high feasibility scores, with media experts rate on 88.57% and material experts rate on 95%. During the developing stage, a trial to students yielded a score of 4.81 out of 5, classifying the media as "Very Good". Students praised its clarity, ease of use, and ability to make learning enjoyable. This study highlights the potential of Kodular-based media to increase engagement and support student-centred learning in vocational education.

Abstract

To improve the performance of wireless communications in indoor environment, it is important to optimize the signal quality by reducing the error rate between the received signal strength based on experimental data and estimating data. Due to the complexity of modern building layouts and construction materials, estimating received signal strength values based on these structural elements is challenging. The aim of this paper is to analyze received signal strength of the specific area by using the path loss exponent model of ray tracing techniques. In indoor environments, modeling radio wave propagation involves estimating the received signal strength at various points based on the layout and geometry of the space. This study involved three placement of 1.8 GHz AAU5940 Wall Mounted transmitters at height with 11.12 m and at different distances with 44.81 m, 95.4 m, and 108.2 m of specific receiver building. The Received Signal Strength Indicator (RSSI) readings are typically recorded to analyze and understand the ray tracing technique characteristics in a wireless communication environment. This paper presents analytical result of some practical experiments that helps to build an optimized signal quality for indoor environment using mathematical modelling with the help of MATLAB software.

Abstract

This study aims to develop a web-based registration system for prospective parking attendants at the UPTD Parking Service in the Transportation Department of Batam City. Currently, the process of managing prospective parking attendant data is done manually, leading to time-consuming registration procedures. The absence of a proper information system makes it difficult for prospective parking attendants to find information about the registration process at the Batam City Transportation Department. This system was developed by using PHP programming and MySQL database. The development follows the SDLC Waterfall model, which consists of five phases: requirements analysis, system design, coding, program testing, and system implementation. The system was modelled by using Unified Modeling Language (UML), including use case diagrams, activity diagrams, class diagrams, and sequence diagrams. System testing was conducted by using black-box testing and tested by users. The results of this study include the requirements analysis, system design with UML modeling, and eight supporting tables for the development of the web-based application. The system has been tested on local host and through black-box testing, and it is deemed successful in assisting the management of prospective parking attendant registration. However, the application is limited to the admin and user pages. There is a need for data classification on the system dashboard to present a more executive-level display in line with the registration form for prospective parking attendants. Additionally, there is a need for improvements in human resources to ensure proper operation and maintenance of the system.

Abstract

Education is one of the main pillars in developing quality human resources. To ensure equal access to education, the government has launched various scholarship programs. However, the management and distribution of scholarships often face challenges in terms of accurate data collection and spatial distribution analysis. This study aims to map the distribution of scholarship recipients in Jambi Province using a Geographic Information System (GIS) approach with QGIS software. The research uses spatial data in the form of administrative boundaries of Jambi Province and non-spatial data on the number of scholarship recipients per district/city obtained from the JDAC Jambi official website. The data were processed using attribute joining, classification with the Natural Breaks (Jenks) method, and visualization through a choropleth map. The results show that scholarship recipients are unevenly distributed, with higher concentrations in urban and densely populated areas such as Jambi City and Muaro Jambi Regency, while regions like Tebo and Sarolangun have relatively low numbers. This indicates the influence of population density, availability of higher education institutions, and information accessibility on scholarship distribution. The use of QGIS proved effective in presenting spatial data visually and supporting data-driven policymaking. The study recommends that local governments utilize spatial analysis in scholarship distribution planning to enhance equity and program effectiveness.

Abstract

Low student learning outcomes in Chemistry at SMAN 1 V Koto Kampung Dalam, Padang Pariaman Regency, are caused by teachers' limitations in utilizing interactive digital learning media. Learning is still dominated by conventional methods, while students need attractive visual and digital media to understand abstract Chemistry concepts. This study aims to develop and test the validity, practicality, and effectiveness of a Google Sites-based Learning Management System in Chemistry learning. The method used is Research and Development (R&D) with the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects consisted of 30 grade XI students selected through random sampling from a total population of 92 students. The research instruments included an expert validation sheet, a teacher and student practicality questionnaire, and a learning outcome test (pre-test–post-test). The results showed that the Google Sites-based learning management system was rated "Highly Valid" by subject matter and media experts and "Highly Practical" according to teacher and student responses. The effectiveness test using the Wilcoxon Signed-Rank Test produced a significant value of 0.000 (<0.05) and an N-Gain score of 0.83 in the "Effective" category. Future work is recommended to integrate this learning management system with learning analytics and mobile learning features to expand its effectiveness in sustainable digital learning.
