Light Intensity Control and Greenhouse Monitoring System for Melon Cultivation

Melon plants require a photosynthesis process ranging from 10 to 12 hours per day. Cultivating melon plants at the greenhouse of Institut Teknologi Telkom Surabaya is challenged by the fluctuating climate of Surabaya City, which can impact the received light intensity and result in a deficiency for required photosynthesis. In addition to the light intensity level, the selection of light color for specific growth phases also influences plant development. Therefore, the purpose of this paper is to create a monitoring and light intensity control system in the greenhouse based on the color spectrum of the growth phases of melon plant, to support the growth and development of melon plants. The Fuzzy Mamdani method was chosen to establish rules for the percentage of light color based on light intensity and the growth phase of melon plants. The results show that the system's outcomes using the fuzzy method achieved an accuracy of 99.92% with a margin of error of 0.08% for the blue LED, 99.74% accuracy with a margin of error of 0.26% for the red LED, and 99.95% accuracy with a margin of error of 0.05% for the white LED, in contrast the web-based monitoring system is capable of displaying light intensity data, plant growth phases, and lamp statuses.
