| Summary: | Water usage in Indonesia mostly used by farming sector, there is 2 type of
farming methode. Firstly is indoor farm, and second is outdoor farm, for outdoor is
done in open land that farming is depend on the weather outside in farming land.
Meanwhile for indoor farm it is usually done in building like green house or screen
house where not all the weather is affect the plant inside the building.
One of the most important things in water usage in farming sector, is to
determine the total water that plant need in irrigation. To determine the total water
that plant need we can use many different methode, one of them is by determine
evapotranspiration reference, to determine this reference weather data and time data
required. Where the intended weather data is air temperature, air humidity, wind
speed, and solar irradiation. And where the intended time data is day of the year, and
exact hour of the day where the weather data picked. Other than those 2 data, this
methode require location data too, the geographic location and the elevation of the
land.
Location data is a static data, where it can only be change because the location
of the instrument is moved, but the time and weather data is dynamic data where time
data will change over time, and weather data will change because of local climate
change every time. So for this methode weather station is required.
This research will cover about development of measuring instrument for
weather (temperature, humidity, wind speed, solar irradiation) called node sensor that
will be placed in screen house. The discussion will talk one-by-one from the
background of the research, literature study, design and implementation, and lastly
about the test evaluation. At the end of research, the measuring instrument for air
temperature, air humidity, wind speed, and solar intensity. The measuring instrument
will have several properties that is: is wireless, uses communication that can connect
to gateway that gateway has internet access, and self charging using solar panel so it
can survive in remote location that has no power supply. |
