Abstract
Peristiwa alam seperti gunung berapi selalu meresahkan warga didaerah sekitar gunung akibat dampak yang ditimbulkan terutama gas beracun. Ada beberapa gas yang beracun yang sering muncul saat gunung meletus yaitu Karbon Monoksida (CO), Karbon Dioksida (CO2), Hidrogen Sianida (HCN), Hidrogen Sulfida (H2S), Sulfur Dioksida (SO2) yang apabila terhirup dengat tingkat kadar yang tinggi akan sangat membahayakan.
Karbon Monoksida (CO) merupakan salah satu gas berbahaya jika kadarnya melebihi batas normal yaitu 35 PPM. Alat ini bersifat portable dan akan ditempatkan pada jarak sekitar ±100 meter lebih tinggi dari pemukiman warga, sehingga masih ada waktu bagi warga pemukiman untuk pindah (evakuasi) ke tempat yang lebih aman. Sistem kerja dari alat ini yaitu mengukur gas pada ruangan tertutup menggunakan sensor gas CO (MQ7) dan mengukur temperatur daerah sekitar dengan sensor Thermocouple max6675 tipe K. Data yang terbaca oleh sensor akan diteruskan ke Arduino Uno dan akan di telemetering dengan media gelombang radio (transmitter) dan ditangkap oleh komputer berbasis LabVIEW yang telah terpasang rangkaian penerima (receiver).
Hasil uji coba dapat memonitor kadar gas (CO) dan temperatur dengan akurat karena sudah dikalibrasi dan dibandingan, sehingga didapat persentase error sensor gas CO (MQ7) sebesar 0,011 - 0,4% dan persentase error sensor thermocouple sebesar 0 - 0,03%. Pengaplikasian alat ini untuk memberikan informasi yang tepat tentang kadar gas CO kepada warga sekitar dengan jarak telemetering 0 - 110 meter mengenai indikasi adanya gas beracun secara real time.
==================================================================================
Natural events such as volcanoes are always disturbing residents around the mountain area most caused, especially toxic gases. There are some toxic gases that often arise when the volcano erupts: Carbon Monoxide (CO), Carbon Dioxide (CO2), Hydrogen Cyanide (HCN), Hydrogen Sulfide (H2S), Sulfur Dioxide (SO2) when inhaled with high levels will be very dangerous.
Carbon Monoxide (CO) is one of the most dangerous gases I will discuss. This tool is portable and will be placed at a distance of about ± 100 meters higher than residential areas, so there is still time for residents to move to settlement (evacuation) to a safer place. The working system of this tool is to measure the gas in a closed room using a CO (MQ7) gas sensor and measure the ambient temperature with a Thermocouple max6675 type K sensor. The data read by the sensor will be forwarded to Arduino Uno and will be telemetering with a radio wave (transmitter) medium and captured by a LabVIEW based computer that has a receiver set up.
The test results can monitor the levels of gas (CO) and tempera-ture accurately because it has been calibrated and compared, so that the percentage error of CO (MQ7) gas sensor is 0.011 – 0.4% and the percentage of error of thermocouple sensor is 0 – 0.03 %. The application of this tool to provide precise information about CO gas content to the surrounding residents with telemetering distance from 0 - 110 meters using toxic gas in real time.
