Shipwreck is influenced by several factors: the ship and the port system on a less than optimal, assuming good weather conditions. Invention in the harbor is to improve the performance of ports in knowing the weight and balance of cargo ships so as to prevent the ship from the possibility of accidents due to problems on the ship and the port. Repair system on the port that is a boatload of heavy gauge loadcell sensor nodes using wire RS485 communication and balance loads on ship detection using a gyroscope with xbeepro wireless communication nodes. Each node in the harbor and the ships built on the master port uses a star topology sensor network to transmit and record data. Master port transmit data by wireless communication xbeepro headed to the central office server port as the port administration database to allow the ship roadworthy.\ud In lab-scale testing of sending and receiving data between the weight of cargo vessels using the harbor master slave-wire RS485 communication at a distance of 80 meters with a 100% success. Data transmission on the angle of the slave ships to the port at a distance of 80 meters with an average error 1.77%. Data using a boatload of heavy gauge loadcell with a capacity of 10 kg has an average error of 3% and the detection data on the balance point of the ship using the gyroscope has an average error of 10.5%.\ud \ud Key words: (star topology sensor networks, wire multidrop RS485 communications, wireless communications xbeepro, loadcell, gyroscope)\u
