| Summary: | The hydroponic method helps increase vegetable production by using water which
is very effective but this method still has drawbacks to changes in the environment
or physical parameters so that production is not optimal. To increase production, a
system for controlling nutrient levels was created. The system is made a growth
model based on machine learning and data obtained from the Internet of Things
(IoT) system. There are 4 environmental sensors that retrieve environmental data
in the form of ambient temperature, ambient humidity, light intensity, water
temperature and Total Dissolved Solids (TDS) content. After the system is
created, nutrient injection experiments will be carried out with variations in the
ratio of nutrients A and B if the Hydroponic PPM value is less than 1000 with a
nutrient content of 9 ml : 9 ml : 1 liter and 4.5 ml : 4.5 ml : 1 liter. Then all the
data is sent to the gateway in the form of the Long Range (LoRa) protocol and
converted into the Message Queuing Transport Telemetry (MQTT) protocol. The
data is processed to produce a graph of physical parameters against time and a
graph of growth over time, both of which will be used as datasets. The dataset will
be input into the Random Forest and Gradient Boosting Training to obtain a
growth model for a hydroponic nutrient control system. The growth model of the
Random Forest hydroponic nutrition control system has an absolute error value of
17.5% and R2 0.91688. As well as good growth for Bok Choy plants is the
injection of nutrients A and B and water of 4.5ml:4.5ml:1 L |
