Description
Summary:The development of digital Archimedes Experiment System Based on Microcontroller for Physics Education has been done. The use of digital systems makes the tools used more effective and time efficient. The digital system used in this device consists of an microcontroller, digital display, power supply and proximity sensor HC-SR04. A microcontroller receives digital data from the HC-SR04 proximity sensor and processes the digital data into the fluid lifting force and mass density that displayed on the digital display. Based on data measurement, accuracy and system accuracy on average 95.06% and 94.88%. In addition, the development is also done on student work sheets. The work sheets developed contain a scientific approach consisting of observing, questioning, experiments, analyzing, and communicating. Based on the results of the validation of experts obtained data that practicum tool has a validity rate of 83% are in the category is very valid. On the other hand, the student worksheet has a validity level of 89.6% are in very valid category.
