“…Simulasi numerik dengan CADMAS-SURF/3D dilakukan untuk mengestimasi rambatan gelombang tsunami (Usman, 2019dan Wicaksono & Usman, 2020, memastikan perilaku gelombang tsunami ketika mencapai pantai (Usman & Rahim, 2017dan Usman et al, 2019, serta menganalisis beberapa tipe topografi dan konfigurasi pantai Murakami & Usman, 2013;Usman et al, 2014;dan Usman et al, 2016). Persamaan dasar dalam simulasi numerik adalah persamaan kontinuitas dan persamaan momentum yang dikenal sebagai persamaan Navier-Stokes.…”

The research aims to mapping the tsunami-prone areas in Watulimo District using numerical simulation methods and spatial analysis as well as compiling tsunami response planning by determining shelters and evacuation routes in a participatory manner according to the characteristics of residents local wisdom of Watulimo District using weighting analysis and network analysis with ArcGIS. The most prone area to tsunami is Prigi Village because it has the lowest topography compared to the other two villages. Determination of shelter is carried out by considering the building function, number of floors, building area, building capacity, distance from the coastline, location from the road, and building construction. Public facilities with the number of floors >1 such as flat, trade facilities; religious facilities; educational facilities; government facilities; as well as health facilities in Watulimo District can be used as shelters during tsunami. Based on the analysis, the shelters obtained can accommodate the population in tsunami-prone areas. The evacuation route can be determined by considering the distance, road width, road conditions, road class, and travel time to obtain the fastest route from settlement to the nearest shelter. The evacuation routes that can be used in Watulimo District are the existing roads. However, there is a need for road repairs in damaged/ potholed road conditions, road widening, adding new roads to facilitate the evacuation process of disaster victims to the shelter, and carrying out routine road maintenance on roads that will be used as evacuation routes, so that these roads are always in good condition.

“…Moreover, the combined effects of sea embankments and coastal forests has also been tested [7] against moats with and without vegetation [8] and a double embankment system has been studied experimentally by varying the spacing between the embankments to understand the energy dissipation through it [9]. Many other studies of composite defense structures [10,11] including the analysis of embankment and vegetation with moat [12], embankment upstream barriers [13] have been conducted, in the recent past. It has been reported in the literature that the flow within such composite defense systems becomes more complex due to the formation of hydraulic jump [14,15].…”

The combination of hard (artificial) and soft (natural) solutions i.e., composite defense systems against flooding and tsunami opens a new window for engineering innovation for researchers nowadays. In this study, the experimental investigation of flood energy dissipation phenomena through composite defense systems comprising of embankment and rigid vegetation models in an open channel flume, is conducted. The flow regime through the composite defense system is classified in two main types, which are further subdivided in two sub-categories. Various combinations of embankment and vegetation and spacing between embankment and vegetation are analyzed. Against the selected range of initial Froude numbers, three different sizes of embankment models, three spacings between the embankment and vegetation (Ldv) and vegetated corridors of two different porosities (PR), are tested to examine the effect of these three parameters on the characteristics of the generated hydraulic jumps and flood energy dissipation within the defense system. It is found that embankment size and vegetation porosity have a greater impact on flood energy dissipation while the selected range of Ldv is less effective. Amongst the assessed composite flood defense systems, the maximum energy dissipation (55%) is observed for the combination of maximum embankment height and vegetation porosity (93%). For fixed combinations of embankment size and Ldv, the maximum increase of energy dissipation (18%) is found for decreasing vegetation porosity from 97% to 93%.

“…It is also happened in education sector, one of the newest technology which is used in the teaching learning process is digital storytelling. By using digital storytelling as a media for teaching writing, the students will have more chance to practice their writing through face to face instruction and distance learning (Santyasa et al, 2019;Sugiyono, 2011;Thohir, 2015). Moreover, students will have new way to learn English, especially to develop their writing skill then hopely will able to help them to acquire English language faster.…”

This research was a Research and Development (R&D) which aimed at developing Local Wisdom based Balinese Digital storytelling through Blended Learning method as an innovative media for teaching writing at Information System Educational Program of ITB STIKOM Bali. The data were collected by using documentation technique, interview, observation, and questionnaire. The collected data were analyzed quantitatively to find out the mean score, in which the mean score was categorized based on the criterion referenced evaluation table. This research found that, (1) In developing Local Wisdom Based Balinese Digital Storytelling Through Blended Learning Method required a chronologically steps, namely: observation, need analysis, designing prototype of the media, expert judgment, revising the product, field testing, analyzing the data and finalizing the final product, (2) furthermore, the result of the questionnaire filled by the students was 3.78, it represented that the implementation of local wisdom based digital storytelling through Blended Learning method could be categorized as good. The results of this study were highly expected can help both the teachers and the students in the process of teaching and learning writing narrative text.
