The purpose of the Environment Control System for radish with Internet of Things project is to control the environment of radish cultivation in a planting house. The working process of this project is separated into two parts. The first part hardware control is to control temperature moisture and illustrated the working status on LCD. The second part software control is collected data from all sensors and then published results on the website via MQTT protocol. The Environment Control System for radish with Internet of Things project is evaluated by measuring the value of temperature and soil moisture from the system compare with the value from reliable instruments. The test results show that the system can measure the temperature and soil moisture correctly. Moreover the software function of the system has fulfilled the requirements.

This special project aimed to determine the appropriate procedure for extending carved dye radish (CDR) and study the type for coating CDR. From the results radish was carved become to rose shape and immersed in peroxyacetic acid 0.08% and calcium choride 1.5% after that was immersed in food dye solution such as blue 0.01% 0.05% and pink 0.01% 0.05%. Then CDR was coated in three types of coating namely xanthangum gelatin and agar. From the result xanthangum has weight loss yield% firmness and color value more than galatin and agar. CDR with blue 0.01% has weight loss yield% 3.24 firmness 3.12 N color value L* 55.09±0.04 a* -20.52±0.07 b* -15.93±0.57 blue 0.05% has weight loss yield% 3.24 firmness 26.01 N color value L* 45.54±0.03 a* -25.70±0.20 b* -26.85±-0.29 pink 0.01% has weight loss yield% 3.09 firmness 23.99 N color value L* 55.03±0.11 a* 29.42±0.05 b* -0.39±0.24 and pink 0.05% has weight loss yield% 3.27 firmness 24.41 N color value L* 45.08±0.07 a* 39.75±0.27 b* 0.30±0.16. The carved radish with blue and pink storage in plastic box stored in aluminum foil at 3-4 ๐C were during 5 days. Microorganism indicated that there were no more than 1×106 colonies per 1 g of sample.
