RANCANG BANGUN SISTEM MONITORING DAN OTOMASI KETINGGIAN AIR PADA GROUND  WATER TANK RUMAH SAKIT BERBASIS INTERNET OF THINGS (STUDI KASUS :RSUD SIDOARJO BARAT) 

DESIGN AND BUILD WATER LEVEL MONITORING AND OTOMATION SYSTEM IN INTERNET OF THINGS BASED HOSPITAL GROUND WATER TANK (CASE STUDY OF RSUD SIDOARJO BARAT)

Ground water tank adalah ruangan bawah tanah yang berfungsi untuk penampungan air sementara dan penyeimbang antara debit produksi dan debit penggunaan air sebelum disalurkan ke roof tank dan konsumen. Selama ini, menentukan ketinggian air ground water tank menggunakan cara manual yaitu menghitung jumlah anak tangga yang tersisa di atas permukaan air. Strategi tersebut memiliki kelemahan dalam hal kecepatan dan akurasi pengukuran. Penelitian ini mengimplementasikan sebuah sistem monitoring dan otomasi ketinggian air ground water tank secara real time berbasis Internet of Things (IoT) pada RSUD Sidoarjo Barat. Sistem ini memanfaatkan sensor ultrasonik untuk mendeteksi ketinggian air, sensor waterflow untuk mendeteksi debit air, dan sensor INA219 untuk mendeteksi daya pemakaian, kemudian data dikirim dan disimpan ke server. Sistem dapat diakses melalui website thingspeak untuk monitoring ground water tank. Sistem mampu menampilkan data ketinggian air (%), debit air (liter/menit), dan daya pemakaian (mW) dalam bentuk numerik dan grafik. Sistem yang telah diterapkan menunjukkan kinerja  cukup baik dengan akurasi sebesar 92,1% ~ 92%. Sistem akan dapat bekerja secara maksimal pada saat pengisian ground water tank yaitu pada debit air sebesar 466,67 liter/menit dengan waktu pengisian selama 3,75 jam.

A ground water tank is an underground chamber used for temporary water storage and serves as a balancing system between the production flow rate and consumption flow rate before the water is distributed to the roof tank and consumers. Traditionally, the water level in the ground water tank has been measured manually by counting the number of steps remaining above the water surface. This method has drawbacks in terms of speed and measurement accuracy. This study implements a real-time water level monitoring and automation system for ground water tanks based on the Internet of Things (IoT) at Sidoarjo Barat Regional General Hospital. The system utilizes ultrasonic sensors to detect water levels, water flow sensors to measure flow rates, and INA219 sensors to monitor power consumption. The data is then transmitted and stored on a server. The system can be accessed via the ThingSpeak website for ground water tank monitoring. It displays data on water levels (%), water flow rates (liters/minute), and power consumption (mW) in both numeric and graphical formats. The implemented system has shown good performance with an accuracy rate of 92.1% ~ 92%. The system operates optimally during the filling process of the ground water tank, with a water flow rate of 466.67 liters/minute and a filling time of 3.75  hours.
