Abstract

This research aims to design and build an automatic dispenser with a microcontroller-based water volume metering system. The system created uses an Arduino Uno as the system control center, a YF-S401 water flow sensor to measure water volume, a solenoid valve and a water pump as a water flow regulator, and three momentary push buttons as input for selecting water volume for 150 ml, 200 ml, and 300 ml. In addition, an LED serves as an error status warning indicator when the water flow sensor fails to calculate the water volume. The research method used is the Research and Development (R&D) method which includes needs analysis, system design, hardware and software implementation, and tool performance testing. Test results show that the device is capable of measuring water with an accuracy of 93.3% at a volume of 150 ml, 96.6% at 200 ml, and 93.3% at 300 ml. Furthermore, the filling time is relatively consistent, with an average filling time of 9.54 seconds for 150 ml, 12.55 seconds for 200 ml, and 18.98 seconds for 300 ml, with a relatively small difference in filling time for each volume. In general, the device is able to work stably and according to the needs of automatic water volume measurement.

Abstract

This study investigates the effect of the Project-Based Learning (PjBL) model on students' critical thinking skills, with collaborative ability acting as an intervening variable, in the context of the Merdeka Curriculum for the Database subject in vocational education. This research was conducted at SMKN 6 Kupang involving 60 eleventh-grade students of the Software and Game Development (PPLG) program. A quantitative approach was employed using path analysis to examine both direct and indirect relationships among variables. The findings of Model 1 indicate that the PjBL model has a significant positive effect on students' collaborative ability (β = 0.390, p < 0.05), explaining 15.2% of the variance. Furthermore, Model 2 reveals that the PjBL model significantly influences students' critical thinking skills both directly and indirectly through collaborative ability. Collaborative ability was found to have a significant effect on critical thinking skills and partially mediates the relationship between PjBL and critical thinking. These results suggest that PjBL not only directly enhances students' critical thinking skills but also strengthens them indirectly by fostering effective collaboration during project implementation. Therefore, the integration of PjBL in vocational learning, particularly in Database subjects, is effective in supporting the development of critical thinking and collaborative competencies required in 21st-century learning and the Merdeka Curriculum framework.
