Abstract

The high interest of mountain climbers in Indonesia also increases the risk of accidents that can occur in climbing. To reduce this risk, we need a tool system that can assist local officers in monitoring the location and condition of climbers. However, due to the many signal limitations and internet connections in mountainous terrain or rural areas, there is a need for other alternative media that can be used to monitor climbers' location and conditions. The LoRa (Long Range) communication module can solve the mountain's limited signal and internet connection. Navigation uses the LoRa SX1276 module based on Radio Frequency (RF) as the transmission medium in the 915 MHz frequency range. The data transmission uses the repeater principle as a bridging medium between devices which can then be displayed via the Android application via Cloud Firestore or Bluetooth media. From the results of the tests that have been carried out, it can be concluded that the system works well in transmitting data via Radio Frequency (RF) with an average RSS reduction of -5.1 dBm every 45 m at a radius of 450 m, Cloud Firestore with an average delay of 0.3855 seconds and Bluetooth with reduced RSSI of -5.5 dBm every 5 m with a maximum radius of 50m. Keyword—Radio Frequency(RF), Wireless, Aplication Android, Cloud Firestore, LoRa.

Abstract

Tingginya minat pendaki gunung yang ada di Indonesia, juga meningkatkan resiko kecelakaan yang dapat terjadi dalam pendakian. Untuk mengurangi resiko tersebut maka perlunya suatu sistem alat yang dapat membantu petugas setempat dalam pemantauan lokasi dan kondisi pendaki. Namun karena banyaknya keterbatasan sinyal dan koneksi internet yang ada pada medan pegunungan, maka perlunya media alternatif lain yang dapat digunakan sebagai media pemantauan lokasi dan kondisi pendaki. Soul Tracking Mobile Junction (STMJ) dapat menjadi solusi pada keterbatasan sinyal dan koneksi internet yang ada di gunung. STMJ menggunakan modul LoRa SX1276 berbasis Radio Frequency (RF) sebagai media transmisi. Pentransmisian data tersebut menggunkan prinsip repeater sebagai media penjembatan antar perangkat yang kemudian dapat ditampilkan melalui Aplikasi Android melalui Cloud Firestore atau melalui media Bluetooth. Dari hasil pengujian yang telah dilakukan, dapat disimpulkan sistem bekerja dengan baik dalam mentransmisikan data melaui Radio Frequency (RF) dengan pengurangan RSSI rata – rata sebesar -5,1 dBm setiap 45 m pada radius 450 m, Cloud Firestore dengan jeda rata – rata selama 0,3855 detik dan Bluetooth dengan pengurangan RSSI sebsesar -5,5 dBm setiap 5 m dengan radius maksimal 50m.
