Abstract

Air mempunyai makna ganda yakni pertama sebagai faktor lingkungan dan ekologi pembangkit sistem; dan kedua sebagai bahan baku untuk kegunaan yang berbeda-beda seperti air minum, industri, pertanian, perikanan, rekreasi, dan lain-lain. Untuk itu diperlukannya sarana pengolahan air minum yang memenuhi kriteria kuantitas, kualitas, dan kontinuitas. Dalam sebuah sarana pengolahan air terdapat sistem control maupun monitoring, sistem tersebut berjalan berdasarkan nilai output dari sebuah sensor yang nantinya akan diproses dalam bentuk lain, sehingga perlu dilakukannya proses akuisisi data serta validasi pada sebuah sensor. Pada penelitian ini dirancang sistem akuisisi data berbasis wireless communication pada sensor Turbidity RK500-07 menggunakan metode IEEE-754 Floating Point Convert serta komunikasi LoRa, dimana output sensor berupa RS485 dengan sistem komunikasi modbus yang terdiri dari master dan slave. Banyaknya bit data biner yang berhasil diterima oleh mikrokontroler akan diekstrak, diolah, disederhanakan dan diconvert untuk mengetahui nilai hexa, sehingga didapatkan nilai decimal sebagai variable kekeruhan air dengan satuan NTU. Nilai yang telah berhasil dikonvert pada master akan dikirimkan ke slave, untuk kemudian dilakukan proses validasi sensor dengan validator turbidity meter TU-2016, dan didapatkan nilai karakteristik static error 5,14% dan akurasi 98,79%. Sensor Tubidity RK500-07 dapat diintegrasikan pada berbagai jenis sistem pengolahan air maupun kondisi lingkungan yang berjauhan antara master dan salve, karena sistem komunikasi yang menggunakan frekuensi gelombang sehingga tidak bergantung pada internet.

Water has dual meanings: first as an environmental and ecological factor in the system's generation, and second as a raw material for various purposes, such as drinking water, industry, agriculture, fisheries, recreation, and others. Therefore, the need for water treatment facilities that meet the criteria of quantity, quality, and continuity is essential. In a water treatment facility, there exist control and monitoring systems, where the operation relies on the output values from a sensor, which will be further processed into different forms. Thus, data acquisition and validation processes are necessary for the sensor. In this research, a wireless communication-based data acquisition system is designed for the Turbidity RK500-07 sensor, using the IEEE-754 Floating Point Convert method and LoRa communication. The sensor's output is in the form of RS485 with Modbus communication system, consisting of master and slave components. The received binary data bits are extracted, processed, simplified, and converted to obtain the hexa value, resulting in the decimal value as the water turbidity variable, measured in NTU units. The converted values on the master will be transmitted to the slave, and then the sensor validation process is conducted using the turbidity meter TU-2016 validator, obtaining a static error characteristic of 5.14% and an accuracy of 98.79%. The Turbidity RK500-07 sensor can be integrated into various types of water treatment systems and distant environmental conditions between the master and the slave due to the communication system's use of wave frequencies, making it independent of the internet.
