Abstract

Abstract—A water management system is being developed in Politeknik Negeri Samarinda (Polnes). The system consists of a number of sensor node (SN) that is always connected to a gateway/sink. Communication network between SNs and gateway is considered to utilize radio technology. As the campus area reaches 10 hectare, long range (LoRa) radio technology might be the candidate. Eventhough LoRa, in its specification, could cover the distance of around 15 km in line of sight condition, Polnes campus that has hilly terrain with several storey buildings may reduce the coverage of LoRa. Hence, in this research, the received signal strength (RSSI) was measured to find the possibility of LoRa being the communication network infrastructure. At the location where the gateway would be installed, a 433 Mhz LoRa transmitter was operated to continuously send data packets. A LoRa receiver was brought to every future SN locations to measure the RSSI. The measurement by the receiver that was equipped with a rubber duck antenna (3 dBi gain) showed that the RSSI is between -107 dB to -85 dB for the distance of up to 165 meter. Meanwhile, by the use of a Yagi antenna with the gain of 7.37 dBi, the RSSI value is between -100 dB to -80 dB. All of those results verify that LoRa is capable for the communication infrastructure of Polnes water management system.

Abstract

Jaringan monitoring penggunaan energi listrik yang dikembangkan Politeknik Negeri Samarinda (Polnes) telah dipasang di lima gedung dalam kampus Polnes sejak tahun 2020 dan menjalani running test selama hampir dua tahun. Walaupun hampir tidak pernah menjalani perawatan, sistem ini secara umum bekerja dengan baik dan hanya mengalami penggantian satu unit mikrokontroler. Walaupun demikian, kemampuan sistem ini perlu terus ditingkatkan antara lain dengan mengubah pola komunikasi yang awalnya searah menjadi dua arah. Pengubahan pola ini akan meningkatkan kemampuan jaringan karena operator tidak hanya bisa mendapatkan data yang dikirim secara regular oleh unit-unit sensor node (SN) tetapi juga mampu mengatur data apa yang diinginkan, bahkan mampu mengatur aktuator yang diletakkan pada SN. Metode yang dilakukan pada penelitian ini meliputi modifikasi mekanisme protokol komunikasi, modifikasi paket data, pemrograman gateway dan SN, dilanjutkan dengan pengujian, dan analisa hasilnya. Hasil pengujian menunjukkan bahwa sembilan jenis perintah dengan tiga inisiator yang berbeda telah menghasilkan mekanisme yang sesuai dengan perencanaan.
