Abstract

The soft skills competencies needed in the industrial revolution 4.0 era on the 21st century are critical thinking, creativity, communication and collaboration or known as 4Cs Skills. This study aims at revealing a teaching activity that can develop and improve the 4Cs skills of vocational education students. This research was a quantitative study using a survey method. The research instrument used a questionnaire of the lecturers' statements about teaching activities carried out by educators to improve or develop the 4Cs skills of vocational education students. The respondents in this study were 403 educators that consisting of 200 educators from Universitas Negeri Padang (Indonesia) and 203 educators from Universiti Tun Hussein on Malaysia (Malaysia). Based on the research findings, it was found that the teaching activity that was most often carried out or appeared with a high percentage in improving students' 4Cs skills was problem solving to improve critical thinking skills, debate to improve communication skills, peer partner learning to improve collaboration skills and finally mind mapping to improve creative skills. Based on the results of this study, lecturers in the implementation of learning need to condition learning activities that can develop students' 4Cs skills, so that the competencies possessed are in accordance with the needs of the developing industry in this 21st century.

Abstract

The rise of smart home technology has significantly impacted people’s behavior and lifestyle, especially when controlling household electronics remotely. Smart homes have become increasingly commoditized in the last decades, resulting in several vendors offering various commercial products and their variants. Universitas Pendidikan Indonesia (UPI) has created the smart home platform “SH-UPI,” which includes the Smart LED Bulb RGB. The platform’s mobile app can be downloaded from the Play Store or the official website (www.sh-upi.com). The SH-UPI is one of Indonesia's leading smart homes that adopted Internet-of-Things (IoT). However, customers have reported issues with the app’s user interface (UI) and user experience (UX), prompting a redesign to address these concerns and stay competitive. This study employs the design thinking method of empathizing, defining, imagining, prototyping, and testing. The define stage to prototype stage resulted in a newly designed prototype for the SH-UPI app. Testing involved evaluating the prototype using metrics like the User Experience Questionnaire (UEQ) and System Usability Scale (SUS). The test results showed an increase in the UEQ parameter value, exceeding the initial average scores of -0.8 to 0.8. Additionally, there was an improvement compared to benchmark scores, which initially ranged from below average to poor but now range from above average to excellent. The SUS score also improved, rising from 59.75 (grade D) to 83.625 (grade A). The findings of this study can be a valuable resource for developing SH-UPI apps with significantly enhanced UI/UX.

Abstract

A simulator is a tool designed to replicate the operations of real-world equipment to aid users in understanding and utilizing them. However, the results of simulator computation often differ slightly from those generated by theoretical calculations. To tackle this issue, various techniques, including theoretical calculations, circuit simulation, and experimentation, are utilized to identify and analyze discrepancies in calculation results between simulators and real-world experiments. This study focuses on TINA-TI, a widely used software for simulating electrical circuits. Specifically, the research examines the analysis of a 3-loop mesh circuit comprising resistors and voltage sources. Four distinct 3-loop mesh circuits are investigated using a multi-step research methodology involving theoretical circuit analysis, simulation on TINA-TI, and practical experiments on a project board. The findings indicate that TINA-TI can accurately simulate straightforward, branched electrical circuits like mesh circuits. However, inconsistencies exist between theoretical forecasts and experimental observations, such as variations in polarity and numerical discrepancies, with certain measurements displaying significant deviations. The aim of this research is to provide insights into the assessment of simulators for simulating basic electrical circuits and to encourage further exploration of the TINA-TI simulator.
