Sistem Pendistribusian Air Bersih Metode Prabayar Terkendali Mikrokontroler Berbasis IoT

A number of problems sometimes often arise regarding the flow of clean water from Regional Drinking Water Companies (PDAMs) to customers, such as the flow of water stops suddenly or there is no water at all, so it is necessary to manufacture a prototype system for monitoring the distribution of clean water with a microcontroller-controlled prepaid method. IoT based. The distribution of PDAM water that is channeled to consumers can be monitored online through the Internet network. The objectives of this research are (a) to make a prototype (prototype) of a prepaid clean water distribution system controlled by a microcontroller based on IoT, (b) to program an Arduino IDE-assisted system, and (c) to measure system performance. The research method starts from making a prototype physical form of clean water distribution assisted by a microcontroller, programming the microcontroller and Wi-Fi module, and measuring system performance. The results of measuring system performance are indicated by an error in the ultrasonic sensor reading HC-SR04 that occurs when the water level is low and too high with a maximum measured water level of 95%. The error when measuring the waterflow sensor at the water level is lower than 49% which is influenced by the water speed from the low pressure pump when the water level is below that value. The accuracy level of the waterflow sensor is 96.96% which is based on the sensor measurement results which are compared to the measurement results with a measuring cup. The system can monitor data readings from the waterflow sensor by using the NodeMCU ESP8266 on a web server from Thinkspeak via the smartphone screen. Overall the tool can function wellSejumlah masalah terkadang sering timbul berkenaan dengan pengaliran air bersih dari Perusahaan Daerah Air Minum (PDAM) ke pelanggan, seperti aliran air terhenti secara tiba-tiba atau ketiadaan air sama sekali, sehingga perlu dilakukan pembuatan purwarupa sistem untuk pemantauan pendistribusian air bersih metode prabayar terkendali mikrokontroler berbasis IoT. Pendistribusian air PDAM yang teralirkan ke konsumen dapat dipantau secara online melalui jaringan Internet. Sasaran penelitian ini, yaitu (a) membuat sebuah purwarupa (prototipe) sistem pendistribusian air bersih metode prabayar terkendali mikrokontroler berbasis IoT, (b) memrograman sistem berbantuan Arduino IDE, dan (c) mengukur kinerja sistem. Metode penelitian dimulai dari pembuatan wujud fisik purwarupa distribusi air bersih berbantuan mikrokontroler, pemrograman terhadap mikrokontroler dan modul Wi-Fi, dan pengukuran kinerja sistem. Hasil pengukuran kinerja sistem ditunjukkan dengan kesalahan pembacaan sensor ultrasonik HC-SR04 terjadi saat level air kondisi rendah dan terlalu tinggi dengan ketinggian air terukur maksimal sebesar 95%. Kesalahan saat pengukuran sensor waterflow pada ketinggian air lebih rendah dari 49% yang dipengaruhi oleh kecepatan air dari pompa dengan tekanan rendah saat ketinggian air di bawah nilai tersebut. Tingkat akurasi sensor waterflow sebesar 96,96% yang didasarkan kepada hasil pengukuran sensor yang dibandingkan terhadap hasil ukur dengan gelas ukur. Sistem dapat untuk pemantauan pembacaan data dari sensor waterflow dengan penggunaan NodeMCU ESP8266 pada web server dari Thinkspeak melalui layar smartphone. Secara keseluruhan alat dapat berfungsi dengan baik
