Pengembangan Perangkat Eksperimen Gerak Lurus Menggunakan Electric Motor Ticker Timer Berbasis Mikrokontroler Arduino
This study aims to design and develop an experimental straight motion
device using Arduino Uno to calculate the velocity, distance, time and acceleration
that has been taken by an object moving in an orderly way or moving straight in an
orderly way. This research is a development research using the ADDIE model with
five stages, namely analysis, design, development, implementation and evaluation.
The steps taken are only up to the product development stage. The experimental tool
was designed to do empirical tests, the validity test was carried out by 4 people
consisting of material experts and media experts, and practicality tests by 3 teachers
and 20 high school students. The product of the experimental device produced is a
straight motion experiment tool along with a guidebook. In order to make it easier for
users to operate a straight motion experiment tool based on the Arduino
microcontroller.
The results showed that the overall acquisition of a precision score on the
straight motion experimental device for speeds ranged from 0.94 to 0.99 with a very
high level of precision. The error rate in the experimental tool ranges from 0.2% -
6.7% with a small error rate category. The results of the validity of the experimental
tools obtained a score of 0.98 and the experimental tool manual obtained a score of
0.97 and were declared valid. Practicality test with scores ranging from 81.25% -
100% in the very practical category for all aspects of the assessment. Thus it is
expected that the experimental tool can help students in learning straight motion
through observations of physical symptoms in real and contextual terms.
