The Monitoring Prototype of Water Physical Condition for Tilapia

Abstract

Tilapia is aquatic organism that is sensitive to water quality parameters such as ammonia, pH, and temperature which means that the monitoring of those parameters become necessary to ensure the healthy development of the fish. To overcome this problem, this research developed a prototype which can monitor the condition of ammonia, pH, and water temperature in Tilapia Fishponds, and the send text message as an alert when the ammonia and water temperature exceed threshold value. The threshold value of ammonia monitoring is 1 mg/L and the threshold value of water temperature monitoring is 32 Degree Celsius. The readings from the proposed prototype are compared against conventional tools (HI 715 ammonia checker for ammonia and MEDIATECH 3 IN 1 quality water tester for pH and water temperature). The results show that the proposed prototype recorded readings within the acceptable range of error. The device is tested in two Tilapia Fishponds. Based on the experiments in 2 Tilapia Fishponds (Tilapia Fishpond A and Tilapia Fishpond B), the prototype can monitor the ammonia, pH, and water temperature with the average errors within acceptable error which are 0.03 mg/L, 0.16 pH, and 0.62 Degree Celsius in Tilapia Fishpond A. The average of measurement error in Tilapia Fishpond B are 0.04 mg/L, 0.37 pH, and 0.36 Degree Celsius. The tests also showed that the proposed prototype can send a text message as an alert to user’s mobile phone.
