Abstract

Tissue culture is one of the technological developments in the field of agriculturalproduction. This technique is one way of vegetative nurseries to produce ready-to-plantseedlings. The benefits of plant propagation by tissue culture include reproducing pantogen-freeplants in large numbers and in a relatively short time. However, in plant propagation by tissueculture it is necessary to pay attention to the factors that affect its success, for exampleenvironmental conditions. Environmental condition factors consist of irradiation intensity,temperature and humidity. The intensity of lighting affects the photomophogenesis process ofthe explants, while the temperature affects the formation of plant organs and the unstablehumidity can make the explants and plantlets grow abnormally. In the Tissue Culture which iscarried out at the Laboratory of the Department of Agricultural Production, the State Polytechnicof Jember, also often finds culture failure or it is called kontam (mushroom culture / rotten culture/ dead culture) due to the influence of an uncontrolled environment. Manual monitoring activitiesrequire more effort and time, and the results obtained are not entirely effective. Based on theseproblems, this study designed a web system that can monitor temperature, humidity, and lightintensity as well as remote control of tissue culture rack lighting based on Microcontrollers andComputer Networks. Thissystem utilizes trending technology, namely the Internet of Things(IoT) and cloud computing. The internet of things allows the results of sensor readings to thetemperature, humidity and light intensity levels of the tissue culture room to be accessed bythewebsite. In addition, it also allows the website to adjust the brightness of the lighting accordingto the needs of the plants. In internet of things communication in this study, the compilers usedthe MQTT (Message Queuing Telemetry Transport) protocol which has the advantage of beingable to run on small bandwidthIntroduction
