Implementasi Fuzzy Logic Mamdani Untuk Sistem Kendali Kualitas Air Pada Budidaya Hidroponik Tanaman Pakcoy Berbasis Internet Of Thing

Abstract

Hydroponics is a method of cultivating plants that relies on water as the main medium for growth, rather than traditional soil-based systems. Due to the absence of soil, hydroponics places great emphasis on water quality, including factors such as nutrient, and pH. The application of a water quality control system aims to stabilize water quality, nutrients and pH needed for the pakcoy get optimal water quality. This sistem uses the fuzzy mamdani method, and hardware uses Arduino mega, nodemcu, also several sensors such as TDS, pH, temperature and LDR sensors. The results of this research provide significant differences, in the first week, plant height and number of leaves using the control system were 5 cm and 4, without the system it was 5.1 cm and 4. The second week, using the control system were 8.2 cm and 8, without the system are 7.7 cm and 7.5. The third week, using the control system was 18 cm and 14, without system it was 15 cm and 11. The fourth week using the control system was 24 cm and 24, without system it was 21.2 cm and 18. Plant weight using system was 270 g, without system it is 177 g.
