Pengembangan Alat Peraga Pengukur Debit Air Menggunakan Sensor Flow Berbasis Arduino Sebagai Media Pembelajaran Fluida

Abstract

Research has been carried out on the development of teaching aid for measuring water debit using an Arduino based flow sensor as a medium of fluid learning in order to determine the feasibility of a water discharge measuring instrument developed as a fluid learning media. This research is development research consisting of the stages of data collection, product design, design validity, design revision, limited trials. The research subjects for the limited trial were the 4th-semester students of the Physics Education Study Program, Muhammadiyah University Purworejo with 19 students. The product developed is a water discharge measuring device that uses an Arduino-based flow sensor as a fluid learning media through the validation stage by experts. Furthermore, the product is revised and limited to trial. From the results of the trial of the tool carried out the Water Discharge Gauge using an Arduino-based Flow Sensor obtained a debit of (3.80 ± 0.13) liters/minute. While the data from the test results taken manually were debit at (3.55 ± 0.31) liters/min. With a relative error that is very small, with a comparison of sensor and manual measurement data on water discharge of 3.40%. This shows the value of the measurement accuracy is very good. From the results of the validation carried out by the validator namely expert lecturers and peers, it was found that the quality of the teaching aids was included in the excellent category with an average percentage of 76% and the quality of the guidebook was included in the excellent category with an average percentage gain of 78%. A limited trial was conducted by conducting a practicum using a water discharge measuring instrument using an Arduino-based flow sensor, then the results of the student questionnaire responses resulted in a percentage value of 87.22% with very good criteria. Thus the Water Discharge Measuring Tool using Arduino Based Flow Sensors is feasible to be used in Fluid material experiments.

Development of Water Distribution and Water Volume Practicum Tools Using the Yf-S401 Flow Sensor on Dynamic Fluid Materials in Senior High School

“…The analysis of teaching aids was carried out by analyzing the deficiencies in previous research that were relevant to the research conducted by the researcher. Based on research conducted by Wahyuningsih et al (2019) still has drawbacks, namely not using the LCD on the teaching aid, so that when it is used as a practicum aid it will be difficult to see the data displayed. In addition, it is not known what volume of water flows from the tank to the reservoir in the data displayed and the presence of water flow from the pump which is sometimes unstable causes the discharge value shown to fluctuate.…”

“…Teaching aids for dynamic fluid material in school laboratories are relatively few and are not owned equally in all senior high schools (Wahyuningsih et al, 2019). This is in line with the results of observations Abdurrahman (2016), the teaching aids available for measuring water discharge are only limited to taps and still have many obstacles such as the operation of teaching aids which are still carried out manually by students so that students do not know the parameters of discharge, volume and time which are measured accurately.…”

Rancang Bangun Alat Peraga Katup Tesla Pada Materi Fluida

“…Melalui alat peraga siswa lebih termotivasi dalam belajar, lebih mudah dalam memahami konsep maupun kemampuan analisisnya [12]. Alat peraga dapat digunakan pada pembelajaran karena dapat memberikan pedoman dalam merumuskan tujuan pembelajaran, lalu memberikan sistematika mengajar, selain itu memudahkan kendali pengajaran, juga dapat membangkitkan rasa percaya diri dalam mengajar, dapat juga membantu kecermatan dan ketelitian dalam penyajian, serta meningkatkan kualitas pengajaran [13]. Dalam penyusunan alat peraga pendidikan bersumber pada proses perolehan informasi melalui panca indera, sehingga jika seluruh panca indera terlibat dalam proses pembelajaran maka pemahaman siswa terhadap materi yang dipelajari semakin baik.…”
