RANCANG BANGUN SISTEM MONITORING GAS BERACUN KAWAH IJEN BANYUWANGI BERBASIS JAVA DESKTOP

Abstract

The increase in the number of visitors to the Ijen crater in Banyuwangi Regency must be balanced with an increase in services to tourists. One of the most important service factors is safeguarding tourists from the dangers of toxic gases released by volcanic craters, namely the Ijen Crater. The potential for the emergence of deadly toxic gas is quite large. Rainwater makes the surface of the hot crater cool. So that the explosion appeared in the crater carrying volcanic gas material. The gas was in the form of hydrogen sulfide (SO2), carbon monoxide (CO) and sulfuric acid (H2S). Since 2013, based on data from the National Disaster Management Agency (BNPB) in the districts of Banyuwnagi and Bondowoso, the toxic gas of Mount Ijen has killed 70 people. This is due to the lack of tools that provide signs of the emergence of toxic gases installed in sulfur and crater areas. Research on the design of toxic gas detectors that have been made can only provide signals in the form of buzzer sounds of toxic gases without providing information on the intensity of the amount of gas in the affected area. Therefore, it is necessary to design a monitoring system that helps read the appearance of the toxic gas detection sensors that can be monitored directly. In this research activity created a java desktop display as a medium for monitoring toxic gas with a sensor connection using serial cable. As a result, the MQ-9 sensor for CO gas and MQ-136 sensor for H2S can detect the presence of both gases and display it in a monitoring system for toxic gas detection based on java desktop.
