Perancangan Antropometri Digital Berbasis Arduino untuk Pengukuran Tinggi Badan di Posyandu Bougenville Kelurahan Cipare Kecamatan Serang

Abstract

Integrated Health Service Posts (Posyandu) play a crucial role in monitoring child growth through anthropometric measurements, particularly height. However, the measurement process at Posyandu is still largely conducted manually using simple tools, which can lead to Errors in measurement and data recording. This study aims to design and implement an Arduino-based automatic height measurement device to improve the accuracy and efficiency of health services at the Bougenville Posyandu in Cipare Village, Serang District. The research method involved the following stages: problem identification, literature review, hardware and software system design, device testing, and community implementation. The system uses an Arduino Uno as the main controller, an HC-SR04 ultrasonic sensor to detect height, and an LCD screen to display measurement results. Testing was conducted on five subjects by comparing automatic and manual measurement results. The results showed that the device had an average Error rate of 0.47%, making it sufficiently accurate and suitable for use in Posyandu activities. The implementation of the device also received positive feedback from Posyandu cadres because it accelerated the measurement process and made it easier to read the results. Thus, this Arduino-based automatic height measurement device has the potential to support more effective, modern, and efficient public health services.
