Rancang Bangun Prototype Smart Greenhouse sebagai Tempat Budidaya Tanaman Hidroponik Berbasis Internet Of Things

Abstract

As a greenhouse, is a building with a translucent roof that has the function of avoiding or manipulating unwanted environmental conditions and desired environmental conditions. The purpose of this research is to design and build a smart greenhouse prototype that can be monitored and can be controlled automatically remotely. The analytical method used is the experimental method, namely through the implementation of experiments and calculations directly in the field. The data used in this study is composed of primary data through the use of an IoT (Internet of Things) network that connects the smart greenhouse prototype with the blynk application used to monitor conditions in the greenhouse. The research results explained that in the smart greenhouse prototype the highest air temperature occurred at an average temperature of 42oC, while the lowest air temperature occurred at an average temperature of 29oC. The highest humidity occurs at an average humidity of 90%, while the lowest humidity occurs at an average humidity of 45%. The highest light intensity occurs at an average light intensity of 31360 Ix, while the lowest light intensity occurs at an average light intensity of 8902 Ix. The highest nutrient temperature occurs at an average temperature of 34oC, while the lowest nutrient temperature occurs at an average temperature of 25oC. The nutrient density tends to be stable, namely 1128-1196 ppm. The results showed that the fixed costs incurred amounted to Rp 110,500/year and variable costs is Rp 23,928/hour. The Break even point in this device is 36 pakcoy plants. The NPV value obtained at a 5% interest rate of Rp 26,469.45/year. The IRR value obtained is 26.565%.
