Efficient Transportation of Disaster Waste in Jetis Region, Bantul Regency, Yogyakarta Efficient Transportation of Disaster Waste in Jetis Region, Bantul Regency, Yogyakarta Christian, Widjaya Christian Widjaya 60219889 村上, 啓介 ムラカミ, ケイスケ Murakami, Keisuke 村上 ムラカミ Murakami 啓介 ケイスケ Keisuke 宮崎大学 University of Miyazaki Disaster waste Optimum Transportation Djikstra Algorithm Hauled Container System Bantul Regency had Yogyakarta Earthquake in 27th May, 2006. Jetis region in Bantul Regency had severe damages due to this earthquake. After this experience, Bantul government needed to have the assessment of earlier disaster waste disposal for a next supposed earthquake. Therefore, this study sets two purposes as, 1) to find a disposal location of disaster waste in Jetis region, 2) to find an efficient transportation that considers both time and cost. This study revealed that the total volume of waste generated under a supposed earthquake in Jetis region is 92.883,2 tons. This volume required a disposal area with 80.111,76 m2, and Karang Semut, which has 9 ha, was proposed in this study. This study set 3 scenarios to evaluate the fastest road network to disaster waste disposal using Djikastra algorithm. This study also set another 4 scenarios, to investigate efficient tranportation of disaster waste with considering both time and cost by using Hauled Container System. As a result, the time for disaster waste disposal in Jetis takes 20 to 22 days with using 60 trucks, and for 8 to 9 days with 150 trucks. The trucks are allocated simultaneously in each village, it takes more days for waste disposal. The total cost is estimated from Rp.715,020,678.23 to Rp.787,828,088.07 depending on the senario. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2020-09-30 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/00010217 https://miyazaki-u.repo.nii.ac.jp/records/6353 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 49 307 311 https://miyazaki-u.repo.nii.ac.jp/record/6353/files/Engineering_49_p307.pdf application/pdf 2.0 MB 2021-06-08
