Abstract
Indonesia merupakan negara yang terletak di antara dua lempeng benua sangatlah rentan terhadap bahaya gempa bumi. Sebagian besar gempa yang terjadi di Indonesia berasal dari gempa di dasar laut dengan kekuatan gempa berskala cukup besar sehingga dapat berpotensi menghasilkan tsunami. Tsunami Early Warning System yang telah diaplikasikan pada beberapa daerah di Indonesia tergolong kompleks pada sistem komunikasi datanya. Sehingga, melalui penelitian ini dirancang sebuah sistem komunikasi data menggunakan gelombang radio Ultra High Frequency, serta menerapkan protokol AX-25 sebagai protokol yang digunakan.
Hasil yang didapatkan pada penelitian ini adalah system buoy dengan gelombang Ultra High Frequency dan daya 2,4 Watt dapat mengirimkan data ketinggian gelombang dengan jarak 4,28 km dengan pada kondisi Line of Sight (LOS) dengan resolusi hingga 1,5 cm. Jarak yang lebih jauh dapat dilakukan dengan penambahan daya pemancar. Protokol AX-25 dapat mengenkapsulasi data pembacaan sensor sebelum ditransmisikan dan mengdekapsulasikan kembali data tersebut setelah sampai di penerima. Pada pengujian BER untuk jarak 3 km diperoleh nilai error sebesar 0,0069.
=================================================================
Indonesia is a country that lies between the two continental plates. This makes Indonesia extremely vulnerable to earthquake hazard. Most of the earthquakes that occurred in Indonesia comes from the earthquakes that occurring below ocean with a large enough magnitude scale so it can potentially generate tsunami. Tsunami Early Warning System which has been applied to several areas in Indonesia is considered complex on communication data system. Therefore, through this research will be designed a communication data system using radio wave by applying AX-25 protocol as the protocol.
The results that obtained in this research is the buoy system with Ultra High Frequency waves and 2,4 Watt power can transmit simulated sea wave heights data with a distance of 4,28 km on the condition of Line of Sight (LOS) with 1,5 cm resolution. The longer distance can be accomplished by the addition of transmitter power. The AX-25 protocol can encapsulates the sensor data before being transmitted and decapsulated it's back after arriving at the receiver. On BER test for a distance of 3 km, we obtained 0,0069 error value.
