Improving Student Achievement with the Application of Smart Trainers Integrated QR Code

Wawan Purwanto — 2025-09-23

The present research aims to demonstrate the enhancement of students' learning outcomes through the utilization of a smart trainer in conjunction with a QR code. This intelligent trainer is designed to display the voltage output values of each sensor on the motorcycle. Additionally, each sensor is designated a QR code, enabling students to comprehend the function of each sensor's performance and verify the theoretical principles linked with the corresponding QR code during practice. The educational method is implemented offline, comprising four sessions in phase F of the Merdeka curriculum. The cohort comprised 20 participants, consisting of 5 educators and 15 learners. The assessment results indicate that student learning outcomes enhanced following the provision of materials.

Analisis Pengaruh Variasi Magnet Permanen dan Lilitan Kawat Terhadap Performa Motor BLDC Menggunakan Simulasi ANSYS Maxwell

One of the driving components of electric vehicles that are often used is Brushless (BLDC) motors which have advantages such as high efficiency, large torque density, and precise speed control. This study aims to evaluate the effect of variations in permanent magnet type and stator winding configuration on the performance of Brushless DC (BLDC) motors. Two types of permanent magnets, NdFe35 and SmCo24, are compared based on their electromagnetic characteristics, such as torque, rotational speed, efficiency, and current consumption. In additional, the stator winding parameters were varied, including wire diameters between 1.3 mm and 1.6 mm and the number of conductors per slot between 14 and 23. The simulation results conducted using ANSYS Maxwell show that the configuration combining NdFe35, an optimal number of 14 conductors per slot, and a large wire diameter of 1.6 mm delivers the best performance, with a maximum torque of 325 Nm, maximum power of 2.91 kW, efficiency of 79%, and a speed of 1241.5 rpm. Although the current consumption is high, the resulting power and torque performance are proportional.

NOx Content Analysis In Ambient Air: Public Policy Perspectives And Implications For Sustainable Development In Padang City

Donny Fernandez — 2025-09-23

This paper presents data from the ambient air quality monitoring of Padang City and its implications for sustainable development public policy. Urban growth and transportation and industrial activities have the potential to increase nitrogen gas emissions. Air monitoring was conducted at strategic locations in Padang City that represent anthropogenic activities. The nitrogen gas concentration data obtained were analyzed descriptively and spatially to identify the level of pollutants in the air. Monitoring results were linked to sustainable development indicators, particularly those related to public health (SDG 3) and cities and settlements (SDG 11). This paper aims to provide input for policy makers to strategize the sustainable development of Padang city.
