AquaStat: An Arduino-based Water Quality Monitoring Device for Fish Kill Prevention in Tilapia Aquaculture using Fuzzy Logic

Abstract

In the Philippines, Tilapia fish farming sector is vital to the economy in providing substantial employment, income and meeting local demand for protein sources of the Filipinos. However, the possible benefits that can be derived from this industry are at stake because of the sudden occurrences of fish kill events. This can be attributed to a wide variety of natural and unnatural causes such as old age, starvation, body injury, stress, suffocation, water pollution, diseases, parasites, predation, toxic algae, severe weather, and other reasons. With the identified severe effects of fish kill events to the fish farmers, consumers and the fisheries industry, advanced measures and methods must be established to alleviate the adverse effects of this phenomenon. To solve the underlying problem on water quality monitoring system to improve freshwater aquaculture, various studies were already conducted. However, these studies merely focused on the reading and gathering of water parameters. In this paper, fuzzy logic was used to come up with a model that can analyze and generate result regarding the overall quality of the water being used in Tilapia aquaculture. The water parameters considered in this paper were temperature, dissolved oxygen, and pH level. The results of the water parameter readings using the conventional method were compared to the data that were gathered by AquaStat to test its accuracy and showed no significant difference. Also, the overall water quality obtained using the conventional method was compared to the overall water quality generated by AquaStat and obtained an accurate result.

Sistem Pemantauan dan Kontrol Kualitas Air pada Budidaya Bandeng Mengguakan Metode Fuzzy Logic

“…Penelitian lainnya yaitu, mengukur kualitas air. Pengukuran kualitas air pada penelitian ini fokus hanya pada sistem pemantauan dengan menggunakan logika fuzzy untuk menentukan nilai tingkat kualitas airnya, namun untuk kualitas air yang diukur bervariasi, yaitu pH, suhu, kekeruhan, salinitas [11][12][13][14]. Berdasarkan beberapa penelitian yang telah dilakukan, penelitian yang akan dilakukan yaitu mengukur tingkat kualitas air khususnya mengukur suhu, salinitas, dan kekeruhan.…”
