Daerah Istimewa Yogyakarta (DIY) merupakan salah satu wilayah di indonesia yang memiliki tingkat risiko bencana gempabumi yang tinggi, hal ini disebabkan karena wilayah nya yang berbatasan langsung dengan zona subduksi lempeng dunia yang sangat aktif yaitu lempeng indo australia yang menyusup kebagian bawah lempeng auresia, selain itu terdapat sesar Opak yang sangat aktif di darat. aktivitas sesar Opak inilah yang di duga menjadi penyebab gempabumi besar yang terjadi pada 27 Mei 2006. Gempa 2006 ini menghancurkan Yogjakarta dan sekitarnya yang menyebabkan 5.782 korban jiwa, puluhan luka-luka, dan ratusan ribu rumah rusak. Penelitian ini bertujuan untuk mengidentifikasi potensi bahaya gempa bumi menggunakan metode mikrozonasi untuk mengevaluasi dan memetakan daerah di DIY yang memiliki risiko gempa tinggi berdasarkan perhitungan nilai percepatan tanah maksimum (PGA) pada batuan dasar dan data Vs30 sebagai karakterisasi lokasi akibat pengaruh kondisi tanah setempat. Dalam penelitian ini metode yang digunakan adalah dengan menggunakan perhitungan Probabilistic Seismic Hazard Analysis (PSHA), metode inversi HVSR dan Multichannel Analysis of Surface Waves (MASW). hasilnya adalah peta percepatan tanah maksimum (PGA) di batuan dasar dan peta percepatan tanah maksimum di permukaan tanah di daerah istimewa yogyakarta yang dapat digunakan sebagai informasi awal sebagai pertimbangan pertimbangan dalam menentukan aturan mengenai desain/standar gempa- bangunan tahan gempa sebagai upaya mitigasi gempa struktural.

Tectonic conditions that are vulnerable to earthquakes have become a trigger for researchers to conduct studies on subsurface conditions in East Java. A seismic tomographic study based on the P-wave and S-wave velocity models was applied to identify crustal structures in East Java. The research data totaled 3,893 earthquake events and 28 stations from the Meteorology, Climatology and Geophysics Agency (BMKG) in the 2009-2017 period covering coordinates 5oSL- 11oSL and 110o - 115o EL. The modeling results in this study are expressed in velocity perturbations against the ak135 one-dimensional reference velocity between -5% to 5%. The results of this study indicate that in the central of East Java, there is a negative velocity anomaly which is identified as a sedimentary layer that fills the basin in the Kendeng Zone and volcaniclastic deposits in the Southern Mountains Zone to a depth of 5 km. The dominant negative velocity anomaly in southern East Java is associated with the presence of intrusive and bedrock in the Southern Mountain Zone. The transition zone between the crust and upper mantle in East Java is observed at a depth of 35 km below the surface.

Kabupaten Bantul merupakan salah satu wilayah di Yogyakarta yang memiliki potensi bencana gempabumi dan tsunami cukup tinggi, karena wilayahnya dilintasi patahan aktif (Sesar Opak) dan juga berdekatan dengan zona subduksi yang merupakan zona tumbukan lempeng Indo Australia dan lempeng Eurasia yang dapat membangkitkan tsunami. Sebagai salah satu tujuan pariwisata favorit di Yogyakarta, peningkatan kepadatan penduduk dan lahan terbangun baru juga semakin tinggi. Kondisi tersebut sebagian besar didominasi oleh permukiman, perdagangan, jasa dan pariwisata. Meningkatnya aktivitas di Kabupaten Bantul tentunya membuat kawasan tersebut memiliki tingkat kerentanan yang tinggi akibat pemanfaatan lingkungan yang tidak terkendali dan tidak diatur. Percepatan pertumbuhan tanpa manajemen risiko dan aset yang semakin menua merupakan pendorong utama meningkatnya jumlah korban, kerusakan bangunan, dan kemiskinan akibat bencana. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengidentifikasi tingkat kerentanan dan variabel dominan yang menyebabkan rentan ditinjau dari aspek sosial, ekonomi dan kepadatan bangunan dengan menggunakan 13 variabel kerentanan dan dianalisis dengan metode “Self-Organizing Maps (SOM)” untuk mengelompokkan (cluster) wilayah penelitian. Hasil dari penelitian ini menunjukkan bahwa daerah yang memiliki kerentanan tertinggi terdapat di cluster 2 dan 3 yaitu Kecamatan Bantul, Kasihan, Imogiri, Banguntapan dan Sewon, dengan variabel dominan yang berpengaruh yaitu disabilitas 12,73 % dan fasilitas rumah ibadah 9.24%. Hasil dari penelitian ini dapat digunakan sebagai dukungan praktis kepada praktisi, para pemangku kepentingan dan pengambil keputusan dalam upaya mitigasi dan perencanaan kontinjensi dimasa yang akan datang.

Indonesia is one of the countries that has a fairly high level of natural disaster vulnerability. Mount Sinabung is a strato-type volcano. Administratively, Mount Sinabung is in the Karo Regency, North Sumatra. The eruption of Mount Sinabung has had a very significant physical, psychological and social impact on society. In facing a disaster, survivors need to survive and continue living. The ability to adapt to conditions after experiencing a traumatic event is called resilience. People who lost their homes due to the eruption of Mount Sinabung must be willing to be relocated to new, safer places such as permanent Shelter. Researchers want to see how disaster survivors in the Siosar Permanent Residence respond to being able to recover or recover from their previous situation. The method used in this research is descriptive qualitative with a case study approach. Data collection techniques were carried out using interviews/FGD, observation and documentation studies. The research results show that there are still teenagers who are not yet fully resilient. Researchers found teenagers who have not been able to recover from the problems they faced after the eruption of Mount Sinabung. Therefore, support from various parties or the pentahelix (government, academics, business world, society and mass media) is needed to build sustainable resilience in Siosar Permanent Shelter.

The hospital is the end of service for victims affected by disasters, the frequency and intensity of disasters that continue to increase give great responsibility to the hospital in reducing the rate of injury and even death so that the resilience of the hospital must be bouncy by maximizing all related elements. However, there is growing evidence that many hospitals are vulnerable to disasters, and more effective strategies are needed to minimize disaster risk. This paper uses the method of narrating a literature review with a simple process hierarchy analysis approach to see the priorities of implementing resilience in hospitals. The result of this paper is that hospital resilience will be able to increase by involving the community, both internal and external, by adopting good practices for community-based disaster risk management.

Information technology has emerged to make various activities easier. One of the important roles of information technology is in providing disaster information. River Care Communities (KPS) which are currently spread across several regions in Indonesia, one of which is River Care Communities Opak Gajah Wong. River Care Communities have an important role in helping reduce disaster risks along river flows. There are various kinds of events that have the potential to cause disasters along river flows, including accumulation of rubbish, landslides on river walls, narrowing and shallowing of rivers, rising water discharge above normal limits and the growth of wild plants that can obstruct river flow. Currently the River Care Community only reports its activities conventionally and has not maximized the existence of information technology. With this conventional method, the delivery of incident reports along the river which is their area of activity is often late, the coordinates are inaccurate and confusing because they are not accompanied by visual images. The conventional pattern of submitting reports means that these reports are too late to be followed up by the relevant agencies and are often simply overlooked. To answer the problems mentioned above, the author conducted research by developing an E-Report application based on Android mobile application using the prototyping method. Currently, there are already several similar complaint applications, but they are not specific to problems that exist along the river flow. The form of complaints and reports in river basins has unique characteristics, where the reporter must enter certain values to determine the level of urgency of the report. With this application, it is hoped that every report from River Care Communities Opak Gajah Wong can be conveyed in real time and immediately receive follow-up from the relevant agencies.
