The 2011 Great East Japan Earthquake that occurred on March 11, 2011, had magnitude of 9.0 the Richter Scale with epicenter approximately 70 km east Oshika Peninsula in Miyagi Prefecture. This earthquake triggered terrible tsunami waves which hit coast and propagated around Pacific Ocean. caused extensive severe infrastructural damage, such as damages coastal protection structures buildings, significantly changed river morphology. paper presents tsunami-induced estuarine morphology changes...

The main source of reservoir sedimentation is land erosion in rivers. According to the Nusa Tenggara 1 River Basin Center, Batujai Dam 38 years old and has had very significant shallowing. a dam that problems with sedimentation, compounded by presence water weeds such as hyacinths erosion. As result process, was built does not function properly, its storage capacity decreases, leading reduction dam's agricultural productivity. This study aims determine magnitude rate occurs reference for...

SDN 1 Jembatan Kembar Timur is located in West Lombok Regency, which a zone with medium-high risk of earthquakes and tsunamis, so its residents must be prepared to face it, including schools that are gathering places for many young students who at panic during an earthquake. This community service activity aims transfer information through counseling earthquake simulations train the preparedness teachers students. was carried out using simulation method, attended by grade 6 The results...

The shoreline analysis around the Nanakita River mouth has been performed by utilizing aerial photographs to reveal different behavior between left and right side of river mouth. on moving more dynamically than side. empirical orthogonal function (EOF) method is also applied data change. first mode variability reflects cross-shore movement which shown uniform advance retreat along beach. change dominated 80% contribution mode. second depicts longshore sediment only contributes 10% reveals...

A strong earthquake had been occurred on Friday, August 19th 1977 in Indonesia. The is known as Sumba Earthquake because originated at under the seabed south side of Island with magnitude Mw 8.3. triggered tsunami wave, which propagated toward Sumba, Sumbawa, Lombok and Bali Island. Some post disaster field survey conducted immediately to assess casualty material losses disaster. information this very limited due situation that time. access some locations are difficult lack transportation...

Gili Trawangan is a small island in North Lombok Indonesia which famous with its beauty of white beach and coral reefs. In the last decade, north suffers erosion. The erosion almost along ±650 m retreat as far ±50 landward. coastal protection plan needed due to importance economic value tourism business. Survey field investigation was performed analyze mechanism utilization submerged breakwater proposed for because aesthetic environmental consideration place. Reefball Concrete Beam were...

The past earthquake records in North Lombok show the high level of hazard this area. maximum magnitude was 6.4 Mw on May 30th, 1979. But, there were no tsunami events due to those earthquakes. Nevertheless, area is very close Mataram City (province capital city) and tourism Therefore, assessment important. simulation conducted by using COMCOT Model, which based Earthquake as initial condition. result shows prediction travel time about 18 ~ 20 minutes from source location City. height wave...

Multilevel drip irrigation with PVC pipes is an efficient method that has the potential to be applied in urban settlements. Even though land used not very large, farming can done effectively because it uses polybag land. This study aims determine effect of variations pipe networks amiter on distribution, uniformity, and soil moisture levels duration. The test was carried out four tower water level a multi-level system, duration t1=5 minutes, t2=10 t3=15 minutes t4=20 minutes. data analyzed...

Abstract West Nusa Tenggara was ever hit by an earthquake and tsunami on August 19 th , 1977. This made impact the area of Kuta Village Central Lombok, which is under Mandalika Tourism Area (MTA) development now. research conducted assessment MTA based hazard analysis point view. applies bathymetric data, before topography, after topography to make simulation waves run-up. The run-up used four-wave height scenarios, i.e. 3.5 meters meters, 5 7 development. result showed differences....

Many studies on the Mentawai tsunami have been carried out. Still, not many reviewed validation of run-up height compared to results field in same year as October 25, 2010. The survey reconstruction using COMCOT v1.7 aims validate model output was with study by GITST Team Validation out Aida parameter, calculating ratio comparison between and results. location is divided into 3 layers, namely layer01 covering Sipora Island, North Pagai South layer02 Island layer03 focus observation Sibigau...

Soil erosion in the Nangka watershed has always been a matter of concern. Over last decade, soil led to continuous environmental problems. A thorough examination extent problem was required identify an appropriate conservation strategy within watershed. This study conducted observe rates and map out hazard level. Erosion predictions were analysed by using Revised Universal Loss Equation (RUSLE) model with help ArcGIS software. RUSLE selected because its quantitative ability estimate average...

Tsunami merupakan bencana alam yang mengancam semua kehidupan di pesisir. Kekuatan merusak dari tsunami ini tergantung tinggi gelombang tersebut. Salah satu desa Pulau Lombok terancam oleh adalah Desa Labuhan Haji Kecamatan Haji, Kabupaten Timur. Hal disebabkan letak geografis dan topografis berada pesisir Timur menghadap ke Selat Sumbawa. Oleh karenanya, Penulis beserta tim pengabdian kepada masyarakat Universitas Mataram mengupayakan suatu program Tahan Bencana (DESTANA) disampaikan dengan...

The 2011 Great Tohoku Earthquake and Tsunami in March had caused a lot of damages to people infrastructure Japan. With giant tsunami height plus the subsidence due earthquakes have destroyed most o f nearshore constructions coastal zone areas. According measured data from survey group (Mori et al. 2011); maximum wave at Nanakita area is about 14m. This made topography this region changed drastically. Many breaching places occurred along coast river mouth. study will focus on investigating...

Masyarakat Poktan Beriuk Maju Desa Jagaraga sebagian besar merupakan petani yang memiliki lahan dengan luasan dimiliki bervariasi, dan kepemilikan pekarangan minimal 2 are banyak kosong, sehingga perlu dimanfaatkan untuk pertanian rumahan dalam membantu penyediaan bahan pangan secara mandiri. Adanya sumber-sumber air dari mata disekitar permukiman sumur dangkal, juga dapat diguakan mendukung kegiatan di lingkungan masing-masing rumah potensial. Selain itu memanfaatkan sumber terbatas seperti...

The Great East Japan Earthquake Tsunami occurred on March 11, 2011 induced big change in coastal and estuarine morphology. Tanaka et al. (2011) has already made a report these morphology changes. In this paper, subsequent recovery process after the tsunami is investigated for several rivers Miyagi Prefecture. It found that at Naruse Natori rivers, of river mouth extremely slow due to limited amount sediment supply from adjacent area with structures interrupting longshore movement, whereas...

The shoreline position in alongshore direction around the Nanakita River mouth was measured from aerial photograph which have been taken every 2 months 20 years. Empirical Orthogonal Function analysis used to decompose data into dominant mode of variability for left and right side river mouth. results were also examined relation with wave parameter discharge. first shows same movement between reveals cross-shore process. second its correlation discharge reflects influence long-shore This...
