Abstract

Telah dilakukan kajian probabilitas jatuhnya pesawat terbang di area tapak RDE di kawasan Puspiptek Serpong untuk keperluan perizinan tapak RDE. Tujuan penelitian untuk mengetahui probabilitas kejadian jatuhnya pesawat terbang di area tapak RDE. Metodologi penelitian yang digunakan meliputi pengumpulan data sekunder dan primer, identifikasi sumber potensi bahaya (bandara) di sekitar tapak RDE dan pemetaan sebarannya, penapisan awal menggunakan nilai Screening Distance Value (SDV) dan Kawasan Keselamatan Operasi Penerbangan (KKOP), serta perhitungan nilai probabilitas jatuhnya pesawat di area tapak. Penelitian dilakukan bulan Desember 2015 - Juni 2016. Hasil penelitian menunjukkan di sekitar tapak RDE terdapat 7 lapangan terbang, yaitu Soekarno Hatta (Soetta), Halim Perdanakusuma, Atang Sendjaja, Budiarto, Pondok Cabe, Rumpin dan Pulau Panjang dengan jarak berkisar 11,72 – 79,641 km dari tapak RDE. Berdasarkan nilai SDV (bandara kecil 10 km &  besar 16 km) tapak RDE berada di luar radius SDV bandara. Namun demikian, berdasarkan KKOP (14,5 km), tapak RDE berada dalam radius KKOP dari 2 bandara yaitu Budiarto dan Pondok Cabe. Perhitungan probabilitas menunjukkan bahwa potensi jatuhnya pesawat terbang di area tapak RDE yang berasal dari Bandara Budiarto 0,0066 x 10-7 kejadian/tahun dan dari Pondok Cabe 0,0278 x 10-7 kejadian/tahun. Nilai probabilitas tersebut masih lebih rendah dibandingkan kriteria dalam laporan IAEA (10-7 kejadian/tahun) sehingga tapak RDE dikategorikan aman dari potensi jatuhnya pesawat terbang.

Abstract

ABSTRAK KONDISI GEOMORFOLOGI DAN KARAKTERISTIK SEDIMEN DASAR LAUT DI WILAYAH PESISIR PERAIRAN SEBAGIN UNTUK EVALUASI TAPAK PLTN DI BANGKA SELATAN. Telah dilakukan penelitian mengenai kondisi geomorfologi dan karakteristik sedimen dasar laut di wilayah perairan sebagian, Bangka Selatan. Informasi geomorfologi dasar laut sangat berguna dalam hal interpretasi struktur-struktur geologi yang berada di dasar laut. Sedangkan informasi karakteristik sedimen dasar laut bermanfaat untuk memberikan gambaran perlapisan batuan dasar laut dalam kaitannya dengan kestabilan tapak PLTN terkait aspek kegempaan dan penentuan posisi water intake. Penelitian ini bertujuan untuk mengevaluasi kondisi geomorfologi dan karakterisasi sedimen dasar laut di perairan Sebagin, Bangka Selatan. Metodologi yang dipakai untuk mengevaluasi kondisi geomorfologi dasar laut adalah Multi Beam Echo Sounder (MBES) dan Single Beam Echo Sounder (SBES). Sedangkan untuk karakterisasi sedimen dasar laut dilakukan dengan pengukuran seismik refleksi resolusi tinggi menggunakan sub bottom profiling (SBP) dan uji sampel sedimen di daerah penelitian. Hasil penelitian menunjukkan bahwa daerah penelitian merupakan perairan dangkal dengan kedalaman 1- 59 m. Profil geomorfologi dasar laut daerah penelitian cenderung tidak beraturan dan berdasarkan interpretasi seismik tidak ditemukan adanya patahan. Hasil analisis sedimen dasar laut menunjukkan bahwa, distribusi lumpur mendominasi daerah perairan calon tapak PLTN. Kata Kunci : geomorfologi, tapak PLTN, sedimen, sub bottom profile.   ABSTRACT GEOMORPHOLOGICAL CONDITION AND SEA BOTTOM SEDIMENT CHARACTERISTICS OF SEBAGIN COAST FOR NPP SITE EVALUATION IN SOUTH BANGKA. Study on geomorphological condition and sea bottom sediment in the coastal area of Sebagin, South Bangka Regency, Bangka Belitung Province has been performed. Geomorphological of the seabed was valuable to identify geological structures that exist on the seabed layers. Whereas, sediments seabed characteristics was useful to provide portrait of seabed layer due to the stability of NPP site concerning the seismic aspect and the determination of water intake position. The objective of the study was to evaluate geomorphological condition and sea bed sediment characteristics in the South Bangka sea. Methodology used for evaluating geomorphological of the sea bed were Multi Beam Echo Sounder (MBES) and Single Beam Echo Sounder (SBES). While for sea bottom sediment characteristics, SBP together with sediment sample analysis were used. The result of the study showed that the study area was a shallow water sea with a depth range of 1-59 m. Geomorphological profile of the sea bed tend to be irregular and based on the seismic interpretation, there were no fault exists. Result analysis on the sea bottom sediment showed that clay distribution dominated the study area. Keywords: geomorphology, NPP site, sediment, sub bottom profile.

Abstract

Nuclear Power Plant (NPP) site selection is the key phase of the nuclear power plant process and significantly influence the construction cost and safety. In order to prepare for nuclear power programs in East Kalimantan province, Geographical Information System (GIS) analysis along the coast of East Kalimantan province, especially the Berau district, East Kutai, Kutai Kartanegara, Samarinda, Balikpapan, Penajam Paser Utara and the Paser. The research purpose is to find suitable site for nuclear power plants location using spatial analysis and modeling. The potential Nuclear Power Plant (NPP) site is based on several criteria, such as: geology, slope, soil type, land use, hydrology, and existing road network. Based on the weighting and ranking results using GIS application: there are three locations serve as the potential NPP sites are obtained Kutai Kartanegara and Kutai Timur regency. Next, land suitability analysis is done by using GIS application which shows potential sites suitable general and specific criteria of the site evaluation process development.

Abstract

BOUGUER DENSITY ANALYSIS USING NETTLETON METHOD AT BANTEN NPP SITE. Sub-surface information become crucial in determining a feasible NPP site that safe from external hazards. Gravity survey which result as density information, is essential to understand the sub-surface structure. Nevertheless, overcorrected or under  corrected will lead to a false interpretation. Therefore, density correction in term of near-surface average density or Bouguer density is necessary to be calculated. The objective of this paper is to estimate and analyze Bouguer density using Nettleton method at Banten NPP Site. Methodology used in this paper is Nettleton method that applied in three different slices (A-B, A-C and A-D) with density assumption range between 1700  and 3300 kg/m3. Nettleton method is based on minimum correlation between gravity anomaly and topography to determine density correction. The result shows that slice A-B which covers rough topography difference, Nettleton method failed. While using the other two slices, Nettleton method yield with a different density value, 2700 kg/m3 for A-C and 2300 kg/m3 for A-D. A-C provides the lowest correlation value which represents the Upper Banten tuff and Gede Mt. volcanic rocks in accordance with Quartenary rocks exist in the studied area.
