Abstract

This study aims to overcome the lack of weather monitoring tools in Indonesia. The main factors of extreme weather changes in Indonesia are the rainy season and strong atmospheric dynamics. Weather monitoring tools developed based on IoT, allowing monitoring remotely. The research method used the ADDIE model, with data collected through validation tools and analyzed qualitatively using the Likert scale. Validation by three experts showed an average result of 89.29%, which falls into the very decent category. This tool aims to provide solutions for coastal communities in the city of Bengkulu, allowing them to get early warnings about weather changes, especially strong winds. This tool has been proven to fit its design and works well. Recommendations for future research are the addition of regional classification, replacement of more durable sensors such as other types of DHT sensors, and the addition of data loggers to store previous measurement history.

Abstract

Geographically, Indonesia is located in three rings of active plates and surrounded by various active mountains that make Indonesia prone to earthquakes. When the earthquake occurred, there were still many people who were late in getting information to carry out the early evacuation process. This research aims to provide solutions to people who are late in receiving earthquake information by developing a microcontroller-based earthquake early warning system alarm with MPU6050 accelerometer sensors and NodeMCU ESP8266 to minimize possible losses. This research uses the Research and Development method with the ADDIE development model, to develop an Arduino uno-based earthquake alarm from previous research. This research uses a literature study system for analysis of earthquake problems when an earthquake occurs. The results of this study are in the form of a tool equipped with an Arduino Uno microcontroller system, where the earthquake warning system is run according to the system design. The tools developed were validated by three expert lecturers using validation questionnaires. Data analysis was carried out quantitatively to determine the feasibility of Arduino-based earthquake early warning tools using the Likert scale. Based on the average results of validation tests by experts, 91% of earthquake early warning tools developed are in the very decent category. Based on the trials carried out, the tool can provide warnings to the public directly

Abstract

Students' understanding of learning materials will increase with the presence of teaching aids. This study aims to produce a product in the form of a Doppler effect demonstrator based on Arduino Uno with FC-04 and HC-SR04 sensors in high schools, as well as to assess the feasibility of the developed teaching aids and determine students' responses to the developed teaching aids. This research is a type of development research (RD) using the ADDIE development model. The research subjects consist of 2 physics education lecturers as media expert validators, 1 teacher at one of the high schools in Kota Bengkulu as a material expert validator, and 65 students from12th grade Science at one of the high schools in Bengkulu City. The research instruments used were needs analysis sheets, material expert and media expert validation sheets, and student response sheets. Data collection was carried out through questionnaires distributed to the validators and students. The results of media and material validation tests obtained average scores of 85% each, categorized as very feasible. Based on these results, it can be concluded that the Doppler effect practical demonstrator using FC-04 sensor and Arduino Uno is feasible. As for the student response results, the average score obtained was 85%, categorized as very good.

Abstract

The purpose of this study is to develop an Arduino Uno-based prop to visualize and measure the magnetic field around straight wires and solenoids according to the Biot-Savart law. This tool is designed using HMC5883L sensors that are able to detect magnetic fields in three axes with high accuracy. This research applies the Research and Development (RD) method with the ADDIE model. There are five stages of this research process, namely analysis, design, development, implementation and evaluation. The results of the validation conducted by media experts show that this teaching tool is very suitable for use, with an average score of 88.18%. The application of teaching aids to grade XII students of MIPA 1 SMAN 04 South Bengkulu improved students' science process skills with an average of 90.23% in the "Very Good" category. The students' response to this tool is also very good, with an average of 87.62%, indicating that motivation and understanding of concepts are in the category of "Very Good". These teaching aids have proven to be effective, innovative, and relevant for experiment-based physics learning.

Abstract

Finding out whether it is possible to use props to measure air temperature, humidity, pressure, and wind speed, determining how students respond to these variables, and determining whether high school students have mastered the science process skills (KPS) associated with these variables are the goals of this study. Three experts evaluated an expert validation questionnaire to determine the viability of instructional aids. 36 high school students in the X grade were given student response questionnaires to complete in order to gather their opinions on the instructional aids. Three observers evaluated an observation sheet to determine the students' level of KPS proficiency. Research and development (RD) using the ADDIE model is the methodology used in this study. Electronic parts such an LCD, BME280 sensor, anemometer sensor, and ESP32 microcontroller were used to create the props. The main focus of tool development is the microcontroller. Temperature, humidity, and air pressure are all measured by the BME280 sensor. The anemometer sensor is used to measure wind speed. An LCD displays the sensor measurement data.The findings show that: (1) the produced props' feasibility falls into the practicable category, with an average percentage value of 93.1%. (2) With an average percentage value of 87%, students' replies to the developed results fall into the very good category. (3) With an average percentage score of 93%, KPS mastery falls into the excellent category. These results lend credence to the idea that high school students can learn KPS using the air temperature, humidity, pressure, and velocity monitoring props.
