REAL TIME FISHPOND MONITORING TO OPTIMIZE A NURSERY FRESHWATER WITH DISTRIBUTION DATABASE

The aim of my research is to optimize a nursery freshwater by fishpond monitoring that can be displayed on desktop base so the behavior of fish with fishpond condition can be observed how suitable fish against fishpond where a nursery is affected by the place , the media and the condition. The data were drawn on monitoring is temperature and humidity by more than one sensor taken using one microprocessor. Using temperature sensor to get data condition in fishpond, data from fishpond is processed by microcontroller as an input and sent to desktop to display then distributed on database for data record in real time asynchronous serial communication between PC and microcontroller. Getting ideal condition is the goal of this device, because real time data communication if something wrong or not suitable on media, the fishpond condition can be handled directly by fitting the volume of fish or the condition of water. 28-30C is ideal temperature condition for seedling that influence the appetite of the fish. By using realtime database distribution methodology, The influence of fish quantity and nursery media can be observed and fish behavioral can be recorded every season.


INTRODUCTION
Fishpond monitoring using sensor as indicators biological requires an understanding of the state of pollution of waters, choice of bio-indicators, physiological and behavioral endpoints of fish and principles of the methodology and their potential applications.Here, we discuss monitoring, vision-based monitoring on micro and desktop information application.Water quality monitoring is also essential to meet international regulations that want to assure fish quality and farming conditions.Fish farms facilities can demonstrate that companies have implemented new systems that will put them in much better commercial positions than others that are still working in a traditional way.
Many type of freshwater fish that have a typical behavior in the growth of their life.For example catfish having various types and having different way in their growth.But generally freshwater fish have an ideal condition in growing like a temperature of the water, a density of fish, water contain.With this system, the farmers will know directly the Changes that occurred during the process of enlargement and data monitored can be stored on database so behavioral record each season can be known.
Realtime monitoring can help farmer determining the provision of the amount of fish in the media or fishpond, configuring water temperature by adding sodium ion (Na), magnesium (Mg) and calcium (Ca) to protect from high temperature.The desktop information had a notification on the display monitor that build by Delphi software and distributed access databases through serial interface between micro and computer.

LITERATURE REVIEW
Growing fish influenced by internal and external factor.Internal factor like the condition of temperature that affected by sun intensity, climate, disease, plankton density and the external condition can be caused by flood, rainfall, pollution.Freshwater fish cultivation, harvest generally occurs three times a year.Various research done by monitoring system on farm To see the behavior of animals on enlargement system.With knowing the characteristic each of fish so the farmer will know when the right time to plant, choose what the right type of freshwater fish, amount of fish that be planted.Monitoring system is design a system that can give feedback when the program was do their function [1].
Good or bad condition of growing fish is affected by temperature where the increasing the temperature will cause the solubility of oxygen in declining of water [2].The changes of temperature affect at fish respiration and the respiration of the fish contacting directly with the response of feeding.Have two condition in table 1, the first condition when the temperature under 28 0 C and the second condition when the temperature above 30 0 C.Both of condition had difference influence at fish.Under 28 0 C the water more cold that can cause fish less aggressive on movement and a fungus disease can appear, fishpond bacteria easily growth rapidly because encouragement of residual feed.at 30 0 C above, plankton more easily growth so less oxygen be get by the fish and the fish have low response on feeding because smell sensory in pressure condition.
Quickly addition long larvae in the early phases of is up to speed absorption egg yolks .This water temperature that is too low can resulted in the process of metabolism to be slow this can be impact on growth rate fish larvae will be growing slow [3].The rate of absorption egg yolks increase in line with the improvement temperature .Temperature affect survival rate of the larvae significantly [4].
Automation control system research had done on the cultivation of Patin fish with using automation temperature condition [5], PH and clarity water environment by monitoring system with parameter reference.The result have error average 1,477% PH, 0,688% Temperature and 5,62% water clarity.No distribution database in this system but have reference control.
Real time monitoring research base on web done in cloud with real time getting data and then stored the data via cloud computing [6].But the application not low cost system because there need IP public server, internet network communication, farmer that known internet technology, dedicated network and village area in developing countries difficult to do.It like in the system that was proposed, the different in offline distribution data record.

METHODOLOGY
Methodology that been chosen to develop this system is Waterfall Figure 1.waterfall method [7] This method was used in software side.Requirement is the part to prepare what software that been need to integrate the hardware so the plant can work as designated.Using basic compiler that can be integrated on AVR and implementing on the function of processing ADC, serial communication sending data to computer, displaying data on LCD module, determine parameter on wanted condition.Design is what structure program used in determine the function of plant like looping at one sensor that attached at the edge of fishpond or determine of conditional structure program.Implementation is the state where after the program compiling, the hex format embed on microcontroller by Proteus software simulator if running on the right task, the software were ready to be implemented on the hardware.Integration and testing is the state to integrate software with hardware minimum system by software downloader and running the function with giving the power to test the response function of the system.Maintenance is the state that how the software handled the error or bug on feedback parameter that determined or using system reset by software or hardware.

The part of the system has a functional task that will be an embedded system monitoring.Temperature and humidity sensor there are 2 kind of sensor.LM35 is a temperature sensor that used to get temperature data.It analogous so needed ADC component to conversion the signal.Pin Vout is Analogue signal has produced from LM35 and must be connected to ADC as an input pin ADC.LM35 has operating temperature range on -40 to 110 0 C, 10mV/ 0 C. using DHT 11 to get humidity and temperature parameter, This DHT11 Temperature and Humidity Sensor features a calibrated digital signal output with the temperature and humidity sensor complex.Its technology ensures the high reliability and excellent long-term stability.A high-performance 8-bit microcontroller is connected.This sensor includes a resistive element and a sense of wet NTC temperature measuring devices.The output of DHT11 not need ADC module but use digital pin micro directly.

USB to serial
Is a module that sent data temperature and humidity to computer, through asynchronous serial mode, Tx for transmit and Rx for receive that connected cross model.Microcontroller sending data then accepted by the computer through serial or usb port then adjustment parity, baudrate on hyperterminal for windows or minicom on linux shell.Data from hyperterminal send to access database that controlled by Delphi GUI.
