The tsunami prone area for marine tourism activities (case study: Tulungagung District)

Performance-Based Plastic Design (PBPD) is a structural analysis that can be used to review structural performance. This method is increasingly popular to be used in the earthquake-prone area. This method is based on energy method that can be applied to steel or concrete structures. Meanwhile, Indonesia has already SNI 1726:2102 to be used as a guide in designing the thrust load to review the level of structural performance. Both of these things need to be used as a reference in areas that were initially considered safe from the earthquake but based on the development of earthquake micro zonation maps, it is very possible to become potential areas that also become earthquake regions. For this reason, the case of the structure that was built in the Pekanbaru area was taken. From the analyses of structural behavior, the structure that applied PBPD has greater displacement than the structures that apply the thrust load of SNI 1726: 2012. The percentage of displacement that occurred was 8-37 %. Based on performance analysis, the structures according to PBPD shows a better level of performance to the application of SNI 1726: 2012 thrust load.

ABSTRACTSerang Regency in Banten Province is a multi-prone area of natural disaster, with the greatest potential disasters particularly like floods, landslides, earthquakes, tidal waves, tsunamis, and abrasion. At the time of the Banten tsunami at December 2018, Bulakan Village, Cinangka Subdistrict, Serang Regency was a tsunami affected area that was classified as quite severe. Natural disasters are real threats with non-military threats.The role of relevant ministries/government institutions as the main element in non-military defense also needs attention. The aim of this study is to find the root of the problems and also the solutions related to non-military defense in confronting the real threat in the form of a tsunami disaster that struck the Serang Regency. This research is using a qualitative method supported by the case-study method. All the information obtained from the defined informants was analyzed by qualitative analysis technique. This research also aims to analyze the implementation of coastal area empowerment strategies and institutional synergy mechanism implemented at Bulakan Vilage, Cinangka Subdistrict, Serang Regency, Banten Province.The results showed that the empowerment of coastal areas in the form of institutional synergy in Serang District was carried out with a tsunami disaster management plan based on empowerment of coastal areas such as the development of coastal community disaster awareness, and compiling sustainable plans for a tsunami disaster. Some factors that influence the implementation of the coastal areas empowering strategy in Serang Regency in facing the tsunami disaster are community supports and good communication among the stakeholders.ABSTRAK Kabupaten Serang di Provinsi Banten merupakan wilayah multirawan bencana, dengan potensi bencana terbesar yang meliputi banjir, tanah longsor, gempa, gelombang pasang, tsunami, dan abrasi. Pada saat tsunami yang menerjang Selat Sunda pada Desember 2018 lalu, Desa Bulakan, Kecamatan Cinangka, Kabupaten Serang merupakan daerah terdampak tsunami yang tergolong cukup parah. Bencana alam merupakan ancaman nyata berdimensi ancaman nir-militer. Peran kementerian/ lembaga pemerintah terkait sebagai unsur utama dalam pertahanan nir-militer juga perlu mendapat perhatian, sehingga ditemukan akar permasalahan dan solusi terkait pertahanan nir-militer dalam menghadapi anacaman nyata berupa bencana tsunami yang melanda wilayah Kabupaten Serang. Penelitian ini menerapkan metode kualitatif yang didukung oleh metode penelitian studi kasus. Informasi yang didapatkan dari para narasumber yang dituju selanjutnya dibahas dengan menerapkan teknik analisis kualitatif. Penelitian ini bertujuan menganalisis implementasi strategi pemberdayaan wilayah pesisir dan mekanisme sinergitas kelembagaan yang dilaksanakan di wilayah Desa Bulakan, Kecamatan Cinangka, Kabupaten Serang, Provinsi Banten. Hasil dari kajian ini memperlihatkan bahwa pemberdayaan wilayah pesisir di Desa Bulakan dalam bentuk sinergitas kelembagaan di Kabupaten Serang dilakukan dengan rencana aksi penanggulangan bencana tsunami berbasis pemberdayaan wilayah pesisir yang meliputi pembinaan kesadaran bencana masyarakat pesisir, dan menyusun rencana simulasi bencana tsunami berkelanjutan. Faktor-faktor yang mempengaruhi terselenggaranya strategi pemberdayaan wilayah pesisir di wilayah Serang dalam menghadapi bencana tsunami adalah dukungan masyarakat dan komunikasi yang baik antara para pemangku kepentingan

Volcanic eruption is one of the natural factors that affect land cover changes. This study aimed to monitor land cover changes using a remote sensing approach in Cangkringan Sub-district, Yogyakarta, Indonesia, one of the areas most vulnerable to Mount Merapi eruption. Three satellite images, dating from 2001, 2006 and 2011, were used as main data for land cover classification based on a supervised classification approach. The land cover detection analysis was undertaken by overlaying the classification results from those images. The results show that the dominant land cover class is annual crops, covering 40% of the study area, while the remaining 60% consists of forest cover types, dryland farming, paddy fields, settlements, and bare land. The forests were distributed in the north, and the annual crops in the middle of the study area, while the villages and the rice fields were generally located in the south. In the 2001–2011 period, forests were the most increased land cover type, while annual crops decreased the most, as a result of the eruption of Mount Merapi in 2010. Such data and information are important for the local government or related institutions to formulate Detailed Spatial Plans (RDTR) in the Disaster-Prone Areas (KRB).
