This thesis created to develop a tracking system or locate people in areas that the Internet can access. By using LoRa communication and localization principles in the determination of position by trilatation method, which is a technique for positioning with 3 transmitters or receivers at various points around the area and must have 1 receiver or transmitter at the person who wants to specify the position when making a connection, the signal strength is determined, which distance indicates between the 3 the transmitter scan the transmitter or the transmitter person who wants to specify the position when making a connection, the signal strength is determined, which distance can indicate between the 3 the transmitters the transmitter or the transmitter person who wants to specify the position when making a connection, the signal strength is determined, which distance can indicate between the 3 the transmitters the transmitter or the transmitter person who wants to specify the position when making a connection, the signal strength is determined, which distance can indicate between the 3 the transmitters the transmitter or the transmitter person who wants to specify the position when making a connection, the signal strength is determined, which can indicate between the 3 the transmitters or receivers at various points around the area and must have 1 receiver or transmitter at the person who wants to specify the position when making a connection, the signal strength is determined, which distance can indicate between the other points around the area and must have 1 receiver or transmitter at the person who wants to specify the position when making a connection, the signal strength is
