“…Water blok diletakkan diatas elemen peltier. Heatsink diletakkan di atas kipas kemudian sambungkan kabel elemen peltier dan kipas ke power supply secara paralel sehingga terdapat celah di bawah kipas bertujuan agar udara yang mengalir dari bawah menuju heatsink yang kemudian disambungkan ke sumber listrik AC dengan memakai power supplay DC (Sumarni et al, 2013). Rangkaian Elemen peltier dapat dilihat pada Gambar 2.…”

Telah dilakukan perancangan sistem monitoring suhu pada proses pendingin larutan nutrisi hidroponik menggunakan elemen peltier dan TDS meter. Proses pendingin larutan nutrisi hidroponik menggunakan elemen peltier yang terhubung dengan sensor DS18B20 sedangkan TDS meter menggunakan nutrisi ABmix untuk menghasilkan konsentrasi terlarut sebesar 200 ppm -1100 ppm. Elemen peltier aktif ketika suhu diatas 26°C sedangkan suhu dibawah 26°C elemen peltier mati. Konsentrasi terlarut yang dirancang dapat mengaktifkan buzzer ketika dibawah 200 ppm sedangkan diatas 200 ppm buzzer mati. Data berupa suhu dan konsentrasi terlarut yang didapat kemudian diproses oleh mikrokonteler Arduino Uno kemudian suhu dan konsentrasi terlarut ditampilkan ke LCD. Persentase error yang didapat pada pengujian sensor DS18B20 dengan alat pembanding sebesar 2,08% dan sensor TDS meter dengan alat pembanding sebesar 0,25%.

“…The experiment on zone cooling for plant root has been performed on the aeroponic system for potato (Sumarni et al 2013) and using floating raft hydroponic for onion (Niam et al 2017), which produces good plant growth. Cultivation of plants using floating raft hydroponic technology can be advantageous, although it requires energy for cooling.…”

Lettuce becomes the main ingredient of salad as one of the healthy foods. The lettuce cultivation in tropical areas is often performed in highland. To reduce soil erosion and pesticide contamination, the cultivation of lettuce plants in high open land needs to be reduced. The lettuce cultivation in hydroponic system at tropical lowland requires cooling. The root zone cooling requires enormous electrical energy. However, it can be solved by controlling the temperature based on the automatically. Therefore, it has been developed control and monitoring system for the root zone on floating raft hydroponic system. This study aimed to evaluate the photosynthetic rate of lettuce cultivated in floating raft hydroponic system whose nutrient solution was controlled by the developed control and monitoring system. Statistical analysis was performed to draw the conclusions about photosynthetic variance of lettuce on two hydroponic systems, namely controlled and uncontrolled system. Furthermore, this paper presents an artificial neural network (ANN) model to estimate the photosynthetic rate of lettuce cultivated in the hydroponic systems. The ANN model was comprised of eight input (nutrient temperature, EC, pH, DO, and ORP, air temperature, air humidity, and photon flux density of photosynthetic) and one output (photosynthetic rate). It was noted that the ANN model predicted accurately the photosynthetic rate of lettuce leaves whose R2 was 0.87 for plants cultivated in floating raft hydroponic system whose nutrient solution was controlled by control and monitoring system. The ANN was useful for identifying the photosynthetic rate of lettuce cultivated in floating raft hydroponic systems on tropical lowland.

Developing a control system for hydroponics is gaining high attention because of the possibility to increase resource efficiency in producing high quality vegetables. Applying such a control system for nutrient solution in hydroponics requires less labour and operational cost. Therefore, it is important to develop a control system for nutrient solution in hydroponics. This research was aimed to develop a control system for lettuce cultivation in floating raft hydroponics. The control system has been developed to control temperature, EC, pH, DO, and ORP of nutrient solution in the controlled floating raft hydroponics by using Arduino Mega 2560 microcontroller as a control unit and micro SD card as storage media. The control system was found to be able to maintain the temperature of nutrient solution in the range of 20 to 25°C, EC in the range of 1500 to 1700 μS/cm, pH in the range of 5.5 to 6.2, DO in the range of 4 to 8 ppm, and ORP in the range of 300 to 500 mV. The control system performed well in maintaining these parameters as showed by a better lettuce growth in the controlled floating raft hydroponics, as compared to that of without the control system.
