Abstract

The design of 3D land seismic parameters is a preliminary step before the acquisition of 3D land seismic data to obtain seismic data quality and efficient survey budget. The objective of this research is to obtain high quality of 3D land seismic data based on fold coverage spread on each target layer. The method used is based on the principle of wave propagation or ray tracing method on each target layer, wherein each wave reflection point (bin) will have a different value of fold so that the required configuration of the stretch that will result in the optimal spread of the fold. The applied stretch configurations are orthogonal, brick, zig-zag and slanted where each stretch configuration uses two types of templates that is narrow and wide azimuth. From the simulation analysis results of several stretch configurations in the survey area, then the optimal stretch configuration will be obtained in the survey area. The stretch configuration will be applied is the configuration of orthogonal stretch with narrow azimuth type template. Consideration of the selection of this stretch configuration because it has a more evenly folding effect on the target layer than with other stretch configurations. Furthermore, to obtain the configuration of the appropriate stretch of field conditions, the source point is moved outside the obstacle zone so that the quality of seismic data is maintained.

Abstract

The condition of the Covid-19 pandemic that has occurred since the beginning of 2020 has paralyzed tourism activities in Metro City, Lampung Province. One of the affected tourist objects is the Warak Cave and the Macan Putih Cave, which are located in Tejosari Village, East Metro District. The development of tourist attractions which began to squirm since 2018 was paralyzed due to the outbreak. Entering the new normal era, it can be used as a momentum to introduce the concept of geotourism in Tejosari Village so that the development of tourist objects becomes more attractive in attracting tourists. The method used in this service activity is by direct observation in the field regarding geological conditions which are then disseminated to the community around the cave and to the managers of tourist attractions. The effort made by the service team is to provide counseling about the concept of geotourism and the efforts that can be made to optimize the tourism potential around the cave. The results obtained from this activity are an increase in public knowledge about geological conditions and the concept of geotourism.

Abstract

Desa Batu Balak merupakan salah satu pemukiman yang terdampak oleh tsunami yang melanda Selat Sunda pada tahun 2018. Letaknya yang dilintasi sungai dan berdekatan dengan pesisir pantai meningkatkan kerentanannya terhadap tsunami. Selain itu, tingkat keterpaparan tsunami juga dipengaruhi oleh ketinggian dan kelandaian lereng yang ada. Tujuan dari penelitian ini adalah memetakan tingkat bahaya tsunami sebagai sarana pengurangan risiko bencana di tingkat desa, sesuai dengan Peraturan Kepala BNPB No.1 Tahun 2012 tentang Desa Tangguh Bencana. Penelitian ini memanfaatkan Sistem Informasi Geografis (SIG) untuk menganalisis data dari berbagai sumber, termasuk data SHP, DEM SRTM 30 M Lampung Selatan, dan data tutupan lahan Indonesia dari Badan Informasi Geospasial. Hasil penelitian menunjukkan bahwa kawasan pemukiman di pesisir pantai Desa Batu Balak memiliki kerentanan tinggi terhadap tsunami. Studi ini telah menghasilkan peta zonasi tsunami untuk Desa Batu Balak, yang dapat digunakan dalam pembangunan jalur evakuasi tsunami dan peningkatan infrastruktur desa.
