Portable Device for Monitoring System in Network Culture Laboratory based on IoT

Abstract

Tissue culture is one of the technological developments in the field of agricultural production. This technique is one way of vegetative nurseries to produce ready-to-plant seedlings. The benefits of plant propagation by tissue culture include reproducing pantogen-free plants in large numbers and in a relatively short time. However, in plant propagation by tissue culture it is necessary to pay attention to the factors that affect its success, for example environmental conditions. Environmental condition factors consist of irradiation intensity, temperature and humidity. The intensity of lighting affects the photomophogenesis process of the explants, while the temperature affects the formation of plant organs and the unstable humidity can make the explants and plantlets grow abnormally. In the Tissue Culture which is carried out at the Laboratory of the Department of Agricultural Production, the State Polytechnic of 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 activities require more effort and time, and the results obtained are not entirely effective. Based on these problems, this study designed a web system that can monitor temperature, humidity, and light intensity as well as remote control of tissue culture rack lighting based on Microcontrollers and Computer Networks. This system utilizes trending technology, namely the Internet of Things (IoT) and cloud computing. The internet of things allows the results of sensor readings to the temperature, humidity and light intensity levels of the tissue culture room to be accessed by the website. In addition, it also allows the website to adjust the brightness of the lighting according to the needs of the plants. In internet of things communication in this study, the compilers used the MQTT (Message Queuing Telemetry Transport) protocol which has the advantage of being able to run on small bandwidthIntroduction.
