Abstract


Budidaya ikan dalam kolam semakin bertambah seiring dengan populernya sistem pertanian Aquaponik diperkotaan. Dalam budidaya ikan menggunakan kolam, monitoring kualitas air sangatlah penting untuk menekan tingkat kematian ikan. Salah satu senyawa yang berbahaya bagi ikan adalah Amonia (NH3). Pengukuran Amonia dapat dilakukan dengan menggunakan tiga sensor yaitu sensor pH, suhu dan Amonium (NH4). Untuk memperoleh hasil pengukuran pH yang akurat, proses kalibrasi diperlukan. Kalibrasi sensor pH dilakukan dengan menggunakan larutan HCl, NaOH dan Aquades. Hasil kalibrasi yang diperoleh cenderung linier, sehingga linear trendline approach digunakan. Dengan pendekata tersebut rata-rata error turun 2,833%.
