Figure 1. Map of AF analyses. Colour red, yellow, and green area indicate class 1, class 2, and class 3. 3.1.2. Hypsometric curve and integral (Hc and Hi) The hypsometric integral (Hi) describes the relative distributions of elevations in a given area of a landscape particularly a drainage basin. The index is defined as the relative area below the hypsometric curve and thus expresses the volume of a basin that has not been eroded. A simple equation to approximately calculate the index is (2): Hi= (average.elev. -min.elev.) / (max.elev -min.elev) (2) Hi can be used as an indicator of a landscape stage in the cycle of erosion and divided into 3 stages: young, mature, and old. In the study area Hi varies from 0.16 (subbasin 16) to 0.8 (subbasin 35). Hi values were grouped into three classes with respect to the convexity or concavity of the hypsometric curve (Hc): Class 1 with convex hypsometric curves (Hi≥0.5), indicates young stage; Class 2 with concave-convex hypsometric curves (0.4≤Hi<0.5), indicate mature stage; and Class 3 with concave hypsometric curves (Hi<0.4), indicate old stage [1] (Figure 2; Figure 3; Table 2). Calculation of Hi indicated area of study influenced by erosion, tectonic and rock resistance.

KONFIRMASI PATAHAN PERMUKAAN AWAL BERDASARKAN DATA GEOLOGI DAN DATA GEMPA DAERAH KAWASAN PUSPIPTEK SERPONG. Perka BAPETEN No. 8/2013 menyebutkan persyaratan bahwa tapak industri nuklir tidak boleh terdapat patahan kapabel pada radius 5 km. Telah diketahui bahwa tapak RDE tersusun oleh batu pasir, betu lempung, konglomerat dan batu apung rework yang berumur Pliosen, terdapat kelurusan lembah sungai yang dihipotesakan sebagai patahan. Metode penelitian menggunakan identifikasi potensi patahan melalui pengamatan morfologi, remote sensing menggunakan DEM, singkapan batuan, dan interpretasi hasil seismik. Tujuan penelitian adalah untuk konfirmasi patahan kapabel di sekitar tapak radius 5 km. Jejak penpatahanan permukaan difokuskan pada pengamatan kenampakan bentuk lahan (landform), berupa kelurusan morfologi ataupun lembah, gawir patahan (fault scarp), pergeseran atau offset (sungai maupun bukit), depresi yang terbentuk sepanjang zona patahan, saddle, pressure ridge, dan bentuk sungai serta analisis gempa. Hasil yang diperoleh menunjukkan bahwa tidak ada patahan kapabel dan tidak ada bukti patahan permukaan di sekitar tapak RDE dalam radius 5 km. Kata kunci: Perka BAPETEN, Patahan Kapabel, dan Serpong

... The Baturagung Hills area is influenced by fault activity from the Opak and Dengkeng Faults (Mulyasari et al., 2020). This condition is described bythe results of the seismic hazard assessment which shows that the northern part has a moderate (28.86%) and high (20.83%) ...

... Data processing is carried out by plotting geological data consisting of rock conditions and the position of layers of structural elements at several observation points into observation maps and overlaying with other data that has been adjusted to coordinates. Furthermore, an analysis is carried out based on technical criteria [8]. The research is located on Rempang-Galang Island, Batam City, Riau Islands Province, between 0o29' South Latitude and 04o40' South Latitude and between 103022' East Longitude -109o4' East Longitude, Figure 1. ...
