Analysis Of Gsm (Global System For Mobile) Work System On Gsm Pos Protocol (Product Of Automatic Feed Catfish Pond Monitoring Tool Based On Global System For Mobile)

Abstract

Water quality is one of the important factors for a person's success in conducting fishery cultivation. Water content that is too acidic or alkaline, turbidity level, and water temperature that is too high can cause fish death. In addition, fish must be fed regularly and on time. Therefore, a tool was created that functions to automatically feed and control or maintain pond water quality to prevent death in fish, namely the GSM POS PROTOCOL (Global System for Mobile-Based Automatic Feeding Catfish Pond Monitoring Tool Product). The GSM POS PROTOCOL requires components in the form of an RTC (Real Time Clock) sensor, a water ph sensor, a turbidity or turbidity sensor, and a temperature sensor to obtain water quality report data. Apart from sensors, this tool requires a GSM to send messages and an LCD (Liquid Crystal Display) as a screen to display water quality information. Based on the test results, this tool reads the pH of pool water with a value of 7.09-8.07, a temperature of 25.06°C-26.73°C, a turbidity level of 6NTUs-40NTUs, and has a message-sending delay rate with an average of 18.17 seconds. It can be concluded that this tool has a fairly high level of accuracy, and the fish feed works according to the commands entered in the program.
