A research team from Universitas Gadjah Mada (UGM) has revealed that\nthe discovery of polyvinyl chloride (PVC) resin content at the residence\nof Mutfiana, also known as Fia, in Seyegan, Sleman, Special Region of\nYogyakarta, indicates the fire phenomenon in the house did not occur\nspontaneously. The Centre for Entropy Deceleration Studies (PKPE) at\nUGM\u2019s Faculty of Engineering had previously concluded that the\nmysterious fire phenomenon at Fia\u2019s house was not associated with\nnatural gases, such as hydrogen gas (H2) or phosphine gas (PH3), but\nrather with PVC resin content. This PVC resin is highly flammable when\nit encounters an ignition source. The content was found in fire residue\nthat was uncommonly present on the surface of ceramic walls, wood, or\nplywood in Fia\u2019s house, identified through the FTIR method.<\/p>\n
Sarju Winardi, a lecturer and assistant professor in UGM\u2019s Geological\nEngineering Department who is part of the PKPE team, stated that the\nteam suspects the PVC resin originated from a solvent mixture. He\nexplained that the polyvinyl residue is likely from a substance that was\ninitially a mixture, with the residue being the remaining solid\nmaterial. The source of the fire was the solvent mixture, as the solvent\nwas what escaped and produced the fire. According to Sarju, such PVC\nresin residue is typically found in the combustion remnants of objects\ncontaining solvents like glue or paint. However, he stressed that this\nsolvent cannot ignite and start a fire on its own, nor can it undergo\nself-ignition merely at room temperature. The solvent requires an\nigniter to burn, but Sarju noted the team did not investigate or\nconclude what the igniter was or how the fire was ultimately sparked at\nFia\u2019s house.<\/p>\n
Following this conclusion, PKPE coordinator Alva Edy Tontowi stated\nthat the team\u2019s research into the fire phenomenon is now complete. The\nteam has handed over its research findings to the Sleman Regional\nDisaster Management Agency (BPBD). Previously, the PKPE team had\nconfirmed that the trigger for the mysterious fire phenomenon was not\nnatural gas, finding insufficient strong evidence that the fire appeared\nnaturally and could ignite via an electromagnetic igniter or through\nself-ignition principles. Alva explained that based on the team\u2019s\nresearch and the fire triangle theory principle, the measured\nelectromagnetic field was at a safe level, meaning it was not an igniter\nfor the flames. The fire source was not from natural gas seepage from\nbeneath the surface, there was no thermal anomaly, and no gas was found\nthat could ignite spontaneously at room temperature. The team discovered\nfurther data indicating that the fire burning materials in Fia\u2019s house\nwas likely associated with the presence of PVC resin, which is highly\nflammable when it meets an ignition source.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/ugm-team-says-fire-source-at-fias-house-requires-ignition-to-combust-1781347904", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
