ABSTRACT DESIGN AND IMPLEMENTATION OF PRODUCT, SENSOR SUBSYSTEM, AND ACTUATOR SUBSYSTEM IN SMART GROWTH CHAMBER: SMART AND CONTROLLED PLANT GROWTH CHAMBER SYSTEM By Agung Dwi Laksana NIM: 13218034 (Undergraduate Program in Electrical Engineering) The tropical climate in Indonesia affects the quality of the garlic harvest which is less than optimal. The Indonesian Vegetable Research Institute (BALITSA) has been trying to improve the quality of garlic harvests by conducting experiments through crossbreeding local tropical garlic with imported garlic from subtropical regions. In this effort, a system is needed that is able to emulate subtropical microclimate in the form of a Smart Growth Chamber, which is a smart and controlled plant growth chamber system. In the Smart Growth Chamber there are a sensor subsystem that functions to acquire plant growth parameter data and an actuator subsystem that functions to control plant growth parameters according to the desired conditions. Parameters controlled include temperature, humidity, lighting, soil moisture, and CO2 levels. In implementing the sensor and actuator subsystem, the Arduino Mega microcontroller is used which functions to receive sensor reading data, process sensor readings, send sensor reading data and receive control instruction data from the gateway subsystem, and control each actuator based on the received control instruction data. The product made has specifications of internal dimensions with a volume of 1,000 L. The specifications of plant growth parameters that can be achieved by the product based on testing are temperature - 15°C - 50°C, humidity 45% - 80% (RH), lighting 0 – 2700 lux, soil moisture 50% – 75%RH, and CO2 levels 400 – 5000 ppm.
