Abstract

Frequent floods in Indonesia cause many problems, therefore it is necessary to create devices with the implementation of Raspberry Pi-based IoT Gateways in the LoRa communication system. The gateway has a function as a performance informer and makes it easy to access the exchange of information data and the space to store a lot of data received from the node. To maximize the implementation, a Gateway was designed consisting of Raspberry Pi 3 B+, ESP-32, and LoRa 433 MHz. This research uses the Research and Development method. The data obtained includes how the Gateway works which will be displayed on the Raspberry Pi screen properly, monitoring the state of the water using Thinger io. Data were obtained from the Gateway and data transmission system from Gateway to Client as much as 42 times with an RSSI value of -53.3 dBm in very good condition at a distance of 1.54 km with a wajanbolic antenna and a very poor RSSI of -91.4 dBm at a distance of 8.32 km without a wajanbolic antenna. A poor RSSI value can cause an error. The results obtained from the experiments in the study showed that the implementation of Raspberry Pi-based IoT Gateways in the LoRa communication system on flood detection worked well.

Abstract

Hutan yang di dalamnya terandung sumber daya alam yang melimpah telah memberikan kontribusi positif bagi keberagaman hayati dan hewani serta keberlangsungan hidup masnusia. Dewasa ini baik bencana alam maupun buatan telah banyak mengurangi luas daerah hutan dunia khususnya Indonesia. Penyebab utama dari berkurangnya luas wilayah hutan di Indonesia adalah kebakaran hutan dan penggundulan hutan baik secara legal maupun ilegal. Sebagai upaya dalam pelestarian kawasan hutan di Indonesia, pada penelitian ini penulis membuat robot mobil penjaga hutan dan pemadam kebakaran dini yang diberi nama REBECCA. Robot ini bekerja dengan menampilkan data lokasi dan citra depan robot yang diolah melalui mikrokontroler ESP32-CAM. Gerakjalan robot menggunakan roda dengan motor DC 12V yang dikontrol melalui motor driver L289N. Pengindraan api dilakukan dengan mendeteksi api di area depan robot menggunakan sensor api dan pemadaman oleh modul kipas yang dikontrol oleh mikrokontroler NodeMCU ESP8266. Sebagai antarmuka pengguna, REBECCA menggunakan aplikasi Blynk yang dipasang pada gawai pengguna.
