Abstract

Kekeruhan air disebabkan oleh penumpukan bahan organik yang menyebabkan timbulnya gas-gas beracun sekaligus tempat bersarangnya vibrio yang merugikan ikan. Keputusan Menteri Perikanan dan Kelautan No. KEP.28/MEN/2004 menetapkan standar kekeruhan air untuk budi daya udang di tambak ≤ 50 NTU. Akan tetapi, para petani tambak hingga saat ini masih menggunakan insting dalam menjernihkan air tambak tanpa menggunakan alat ukur yang valid dan sesuai standar kekeruhan. Tren pengukuran dan monitoring yang awalnya hanya berkutat pada wilayah lokal seperti turbidimetri dan nefelometri konvensional, sebenarnya dapat diperbarui keunggulannya melalui kemudahan akses user di mana saja dan kapan saja. Oleh karena itu, digagaslah sebuah prototipe sensor kekeruhan air berbasis IoT menggunakan Blynk platform sebagai interface bagi user. Penelitian ini juga sekaligus membandingkan performa variasi pairing komponen transmitter berupa LED UV dan LED putih−receiver berupa phototransistor, photoresistor, dan photodiode sehingga dihasilkan enam buah pairing komponen sebagai sensor kekeruhan air. Hasil penelitian menunjukkan pengukuran kekeruhan air tambak udang vannamei dengan pairing transmitter-receiver LED UV-photodiode paling mendekati alat ukur standar Lutron TU-2016 dengan eror 2,32 NTU, keterulangan 0,98, akurasi 93,63% dan presisi sebesar ±0,65. =============================================================================================== Turbidity of water is caused by a buildup of organic material which causes toxic gases as well as a nesting place for vibrio which harms fish. Decree of the Minister of Fisheries and Marine Affairs No. KEP.28 / MEN / 2004 stipulates the standard of water turbidity for shrimp farming in ponds ≤ 50 NTU. However, pond farmers are still using their instincts to purify pond water without using a valid measuring instrument according to the turbidity standard. Measurement and monitoring trends that initially focused only on local areas such as conventional turbidimetry and nephelometry, can actually be updated through easy user access anywhere and anytime. Therefore, an IoT-based water turbidity sensor prototype was initiated using the Blynk as cloud storage and user interface. This study also compares the performance of various pairs between transmitter components in the form of UV LED and white LED−phototransistors, photoresistors, and photodiodes as receivers, so that six pairs of components are produced as water turbidity sensors. The results showed that measuring the turbidity of vannamei shrimp pond water by pairing the transmitter-receiver with UV LED-photodiode was the closest to the Lutron TU-2016 validator with an error of 2.32 NTU, repeatability 0.98, accuracy 93,63% and precision ±0,65.
