System of Water Quality Monitoring and Feeding on Freshwater Fish Cultivation

Abstract

Monitoring system has been utilized in many ways. The monitoring system is very useful and helps to alleviate human activities. Starting from industry, livestock, fishery and plantation. For example is fishery monitoring system. This system has been widely used to monitor the quality of water used. Currently fish cultivation is in great demand because of the promising income, especially on freshwater fish. However, many cultivators have problems because of the many fish are dead and the crops that are not maximal. One of the factors that affect these is weather changes that result in an unstable water state. In order to get the expected results, factors that must be considered are water content, temperature and water salt levels that affect the quality of fish metabolism. The standard of water content in freshwater fish cultivation reaches 4 - 9 pH and the temperature must be maintained at 25,5 C- 32,7 C and the salt content is 105μS - 120μS. For the many factors that need to be considered then a system that can monitor the state of water at any time is required. This monitoring system uses Arduino uno as micro controller, equipped with ph sensor, temperature sensor, salinity sensor, LCD, and buzzer. The readable data will appear on the LCD and the buzzer will sound when one of the moisture levels is not at a standard number. Equipped with automated fish feeding system remotely to support this monitoring system.
