This research aimed to develop a dynamic model to simulate the
stomata behavior of red chili plants (Capsicum annuum) in response to
environmental factors such as light intensity, temperature, and humidity in a plant
factory setting. The methodology involved utilizing Vensim PLE 7.35 software to
create a dynamic system model with a causal loop diagram (CLD) to describe the
relationships among the influencing variables. Data was collected from chili plants
cultivated in a controlled growth chamber, and various climate-related factors
were analyzed, including light intensity, temperature, and humidity. Stomata
behavior was simulated using a flow diagram, followed by applying equations to
each variable to generate a dynamic model representing stomata opening and
closing under different light conditions. The model was validated against real
world data using the Mean Absolute Percentage Error (MAPE) method, revealing
error rates of 6.86% for stomata pore area and higher rates for other variables like
light intensity. Despite achieving high accuracy in modeling stomata behavior, the
model's elevated MAPE values indicate the need for further refinement to enhance
its predictive capabilities in practical applications. This methodology optimized
environmental control for sustainable crop production in plant factories.
