Abstract
Sistem Pemantauan Kadar Gas pada Tambang Batubara Berbasis IoT Menggunakan Teknologi Komunikasi LoRa adalah sebuah sistem portable yang berfungsi untuk memantau kadar gas yang berbahaya di tambang menggunakan dua sensor serta modul GPS untuk mengetahui posisi dari alat ini, serta menggunakan LoRa sebagai modul komunikasi. Pembuatan alat ini didasarkan oleh adanya gas yang berbahaya untuk manusia di area pertambangan, dari segi kecelakaan kerja seperti kebakaran atau ledakan yang dikarenakan gas CH4 dan juga sistem pernapasan yang akan terganggu jika terlalu banyak terpapar gas CO2. Oleh karena itu sistem ini dapat memantau perubahan konsentrasi gas. Sensor yang digunakan adalah sensor gas jenis MQ-02 dan MQ-135. Tugas akhir ini mengimplementasikan sistem IoT untuk pemantauan kadar gas di area tambang batubara. Dalam pembuatan alatnya, microcontroller yang digunakan adalah Arduino, dengan dua sensor gas untuk mendeteksi konsentrasi dari gas yang di observasi, GPS untuk menentukan posisi dari alat ini, dan LoRa sebagai alat komunikasi. Alat ini nantinya dapat dibawa oleh pengguna asalkan masih dalam jarak yang stabil untuk komunikasi antar LoRa. Ketika LoRa di transmitter mengirimkan data, LoRa di receiver akan menerima data tersebut dan mengolahnya, lalu dikirim melalui komunikasi serial ke NodeMCU, dan diteruskan ke aplikasi yang ada di smartphone. Pengujian sensor gas di area pertambangan mendapatkan hasil yang berbeda dengan area perkotaan. Jarak komunikasi maksimal yang bisa dilakukan di area perkotaan kurang lebih 600 meter, sementara di area pertambangan dapat mencapai 1,6 Km. Konsentrasi gas yang terukur saat pengujian relatif tidak stabil dikarenakan faktor alam seperti adanya angin.
=========================================================
Gas Monitoring System in Coal Mine Based on IoT Using LoRa Communication Technology is a portable system to monitor gas concentration that can harm us, using two sensors and a GPS module to detect the position of this system, this system use LoRa as a communication module. This system is invented due to the existence of harmful gas for human in coal mine, from the sector of work accident like wildfire or explosion due to CH4 gases and respiratory system disorders due to CO2 gases. Therefore, this system has a capability to monitor the gas concentration change time-by-time, using MQ-02 and MQ-135 gas sensor. In this final project, IoT system is implemented to monitor the gas concentration. This system using Arduino microcontroller, with two gas sensors to observe the gas concentration, GPS to determine the position of transmitter, and LoRa as a communication module. Later, this system could be carried by the user as-long-as they stay in the range between LoRa communication. When LoRa transmitter is sending a data, the other LoRa is receiving the data and process it, then send it to NodeMCU by serial communication, and forward the data to smartphone application. Gas sensor has been calibrated by testing it with various object, such as smoke that was made by burning a paper and cigarette smoke. When the transmitter was tested in coal mine area, results obtained was different when tested in urban area. Results obtained during the test was vary. The maximum range that LoRa could communicate each other in urban area is 600 meters more or less, while in coal mine area LoRa could deliver data up to 1,6 Km. Gas concentration that has been metered during the test relatively goes up and down due to natural factor such as wind blow.
