Abstract
In this paper, soilless cucumber cultivation was investigated, fermented fertilizer to increase the cucumber yield was considered, and the greenhouse temperature control system for cucumber cultivation is developed. To do this, perlite was proposed to replace soil as growth medium. Fermented cows and pigs manure was proposed as plant fertilizer. Combination of fan, water sprinkler, and pipe heating system was proposed to control the greenhouse temperature. However, because this research was conducted during the summer, the greenhouse system observed in this study only focused on variations in the flow rate of the water sprinkles used. The experimental result shows that soilless culture in the greenhouse could be an alternative to traditional field production for high-value vegetable crops. Furthermore, application of fermented fertilizer of 10% could enhance the growth and increase the yield and quality of crops. The proposed sprinkler flow rate is best suited for cucumber crop with the best thrives was 0.846 kg/s.
