DESIGN OF AN IOT-BASED MARINE TRANSPORTATION ACCIDENT RESCUE AND DETECTION SYSTEM BY USING SOLAR PANELS AS AN ENERGY SOURCE

Abstract

The use of sea transport is a means of mobility between islands that is often used by the Indonesian people. Data on shipping accident investigations by the KNKT in 2018-2021 show that the number of victims who died / disappeared was 342 people. The purpose of this design is to reduce the number of victims of sea transportation accidents. This design uses a quantitative experimental method. The stages carried out include secondary data collection, product design, manufacturing, testing, and product evaluation. This design is a bracelet equipped with an airbag and GPS module and uses the LoRaWAN network as data communication. The results of data communication testing, it can be concluded that the range of LoRa data communication reaches a distance of 2 km. Based on the test results, it is also concluded that the average error on the NEO-6MV GPS module ranges as far as 1.82 meters from the actual position. The airbag capacity test shows that the airbag used as a buoy can be used by victims with a body weight of up to 86 kg. The results of the power calculation in this design show that the battery discharge and charging time are about 27 hours and 7 hours, respectively.
