Implementation Of Global Positioning System (GPS) Module In Motor-boat Crossing Tracking System Using Lora Communication Protocol

South Kalimantan is an archipelagic region characterized by a large number of river systems that flow from the interior to the sea. Rivers function as a source of livelihood and a transportation route for people and goods. Current technological advances and developments is the Internet of Things (IoT). This technology is utilized by creating a system that can monitor the location of motorboats so that community needs can be met. So a system was created that can determine the location, distance, speed and estimated time of arrival of motor boats. This research aims to determine the accuracy of the latitude and longitude coordinate data for motorboats currently operating on the Motorboat Crossing Tracking System and to calculate the distance, speed and estimated time of arrival of motorboats based on GPS coordinate data on the Motorboat Crossing Tracking System and GPS on Android cellphones. This research was carried out using the NodeMCU microcontroller, NEO-6M and Lora modules. The research was carried out for 2 days and it was found that the accuracy of the motor ship's latitude and longitude coordinate data for the first test was 96.96% and the accuracy value for the second test was 93.59%. In calculating the distance, speed, and estimated time of arrival of motor ships, the average error for the distance parameters was 4.8%, speed was 32.9%, and the estimate was 8.1%. So the accuracy value for the distance parameter is 95.2%, speed is 67.1%, and estimation is 91.9%.
