Abstract

This research aims to create an Internet of Things (IoT)-based Newton's Law II physics practicum trainer. The developed props aim to make the students understand measure time, speed, and acceleration in Particle Dynamics Using IoT-based teaching aids. The design of teaching aids uses electronic components such as ESP32 WIFI-Bluetooth microcontrollers, obstacle Infrared Sensors, and LCDs as the main hardware components. The software for developing this teaching aid utilizes the Arduino IDE compiler based on C++. The development research method used is the ADDIE design development method. The ADDIE design development stages include Analyze, Development, Implementation, and Evaluation. The product feasibility test involved 35 SMAN 1 Montong Gading students. Expert validators in the media and material carry out the feasibility test. The feasibility test results in the media and material sector are 95%, with a very feasible category. The scores of the student's responses to the development are 77% with a practical. The results showed that the physics teaching aids developed were very valid and feasible to use.

Abstract

Indonesia is an archipelagic country located between the Indian Ocean to the south and the Pacific Ocean to the north. As a consequence of this, during the rainy and transitional seasons, extreme weather occurs, especially in the southern coastal areas. According to data from the National Disaster Management Agency, in the last six years, more than 200 tidal waves and abrasion have hit the coastal areas of Indonesia. These conditions can lead to various disasters, particularly tidal flooding. Therefore, the development and design a wave height monitoring device as an early warning system for tidal flooding is necessary. This device is expected to play a vital role in disaster mitigation, because it can provide the information about the potential for tidal flooding based on the changes in wave height. The design of this device uses the LPD3806 encoder as a sensor and the nRF24L01 to send information to the monitoring station. Furthermore, running tests has been conducted and based on the results of the maximum distance test, information delivery can reach 800 meters in an open area with a maximum delay of 2 seconds. For sensor accuracy, a value of  99.7% was obtained, indicating the sensor has a small measurement error rate. On top of that, during field tests, the device demonstrated durability under bad weather, with no loss of data sent. This shows that this device can operate reliably under extreme weather environments.
