Tapa'an Village is a coastal area in Bugul Kidul District, Pasuruan City, which has potential in the fisheries sector, one of the potential fishery products is milkfish. Management of pond water quality is crucial in milkfish cultivation. One management technique is to check pond water quality regularly. Pond water quality can be disturbed or degraded due to various factors. Cultivators usually carry out monitoring using traditional methods and not regularly. Therefore, to get good and optimal milkfish products, it is necessary to use instrumentation technology known as the internet of things (IoT). The aim of this activity is to provide understanding to fish farmers in Tapa'an regarding the application of IoT in optimizing milkfish cultivation. The activity started from the preparation stage, technical guidance, training and mentoring which was attended by the milkfish cultivator group, PKK Activation Team, Village Apparatus, Yudharta Pasuruan University KKN student group, and resource persons from the East Java Provincial Fisheries Service. The survey results obtained after the Bimtek conducted showed an increase in understanding of the material provided in the range of 80% - 100%. The highest percentage level of understanding after Bimtek was in the material on seed selection and feed selection reaching 100%, while the lowest was on knowledge of the benefits of IoT and its application in fish farming at 80%.
