Abstract

Indonesia is located among three tectonic plates, namely Eurasia, Hindia-Australia and Pasific plate. It is affected some tectonic activities such as earthquake and volcano eruption at nearest tectonic zone. On September 31st 2009 around Padang, Pariaman, epicenter 99 52’1.2”E; 0 43’12”S, occurred an earthquake with magnitude 7.6 Mw and as one of disaster mitigation action in the earthquake zone societies, geodynamic analysis nowdays is needed in modelling the earthquake probability. Geodynamic study is easier to be completed by using continued GPS method. It can be analyzed the displacement  at the earthquake phase. This research will examine modelling mechanism earthquake (coseismic) Padang 2009 by GPS continued method using GPS network Sumatran GPS Array (SuGAr) and dislocation model elastic half-space. The results showed that the biggest displacement happened in MSAI station with -6.26 mm on horizontal axis (easting, northing) and TLLU station with 20.83 mm on vertical axis (up). The most fit model for visualizing the mechanism earthquake Padang 2009 is model number 3 with the parameters of width 69 km, slipage -5 m and dipping angle 12.762 . Model number three represented mechanism earthquake Padang 2009 because the highest score of correlation which is -0.71965mm in horizontal displacement and 0.75906 in vertical displacements. It shows that earthquake mechanism that happened in Padang is Thrust Fault

Abstract

3D modeling has become an activity that required by other field, such as for research, visualization, inventory, maintenance, and mapping. Buildings are target object of 3D modeling, one of them is Laboratorium Rekayasa Forensik ITS building as public facility. Photogrammetry as an art, a science and technology focusedon image processingis one of basic of3D modeling, especially Close Range Photogrammetry. Modeling of existing objects can be formed from photos with several methods. 3D Modeling methods that have been developed are Geometry-approach and SFM techniques. Modeling result using Geometry-approach and SFM techniques will be qualified as good if the 3D model has accuracy level 3 (LoD 3). The object research tested are accuracy and suitability of model result to real object. Accuracy is tested by comparing ICP value of observation against ICP value of georeferenced model.The visual aspect is tested by view teh similarity of structure and texture result. While modeling suitability tested using some aspect, that is visually, detail geometry, processing duration, specification, cost, format, data, observation, performance, and file size. From this research generate 3D model of Laboratorium Rekayasa Forensik ITS building that qualified LoD 3, with RMSE value (Easting, Northing, Height) < 50 cm and suitable architecture to real object for both methods, Geometry-approach and SFM technique. Modeling 3D using both methods has each characteristic in detail aspet, duration aspect, specification aspect, cost aspect, data aspect, observation aspect, performance aspect, and file size aspect.

Abstract

Undang-Undang Republik Indonesia Nomor 23 Tahun 2014 Tentang Pemerintahan Daerah merupakan pembaharuan dari undang-undang sebelumnya yaitu Undang-Undang Nomor 32 Tahun 2004 dikarenakan beberapa hal yang sudah tidak sesuai lagi dengan perkembangan keadaan pada saat ini. Beberapa perubahan dalam hal penentuan batas wilayah pengelolaan laut daerah yang terkandung dalam Undang-Undang Nomor 23 Tahun 2014 dari undang-undang sebelumnya yaitu mengenai penentuan garis pantai, batas wilayah bagi hasil kabupaten/kota, serta kewenangan setiap daerah baik provinsi maupun kabupaten/kota.Penelitian ini merupakan bentuk pengaplikasian Undang-Undang Nomor 23 Tahun 2014 dalam memperbaharui penentuan batas wilayah pengelolaan laut daerah. Metode yang digunakan untuk menentukan batas wilayah pengelolaan laut daerah dalam penelitian ini adalah metode kartometrik dengan menggunakan data Citra Satelit SPOT 7 dan Peta Lingkungan Pantai Indonesia (LPI). Objek penelitian ini adalah wilayah perbatasan antara Provinsi Jawa Timur dan Provinsi Bali yang diwakili oleh Kabupaten Banyuwangi (Jawa Timur) dan Kabupaten Buleleng sampai Kabupaten Jembrana (Bali). Dari penelitian ini dihasilkan median line sepanjang 40,3 km yang dibentuk oleh 41 titik, serta diperoleh luas wilayah pengelolaan laut Provinsi Jawa Timur sebesar 23.336,81 Ha dan Provinsi Bali sebesar 23.376,94 Ha serta batas wilayah bagi hasil kelautan untuk kabupaten/kota. Dihasilkan juga peta batas pengelolaan wilayah laut daerah sesuai lokasi penelitian ini.

Abstract

Gempa merupakan fenomena alam akibat aktifitas tektonik yang sering terjadi di Indonesia. Sepanjang pulau Sumatra merupakan pertumbukan antara lempeng Indo-Australia dan lempeng Eurasia menjadikan Sumatra sebagai daerah paling aktif dengan aktifitas tektoniknya. Pada tahun 2010 tercatat tiga gempa besar yang terjadi, yaitu gempa berkekuatan 6,8 SR pada 5 Maret, disusul 6,5 SR pada 5 Mei dan terakhir 7,8 SR pada 25 Oktober 2010. Sebelumnya pada tahun 2009 juga terjadi gempa di padang dengan kekuatan 7,6 SR. Setiap gempa mempunyai kedalaman dan magnitude yang berbeda-beda.Post-earthquake anomali merupakan fluktuasi TEC yang terjadi sesaat setelah terjadinya gempa, fenomena ini terjadi 3 menit hingga 1 jam setelah gempa terjadi. Post-earthquake anomali dapat digunakan sebagai early warning sebelum tsunami datang. Pengamatan TEC (Total Electron Content) dilakukan dengan menggunakan GPS. Satelit GPS akan secara kontinyu memancarkan sinyal gelombang double frequency pada L band. Pada saat terjadi gempa, sinyal yang dipancarkan oleh satelit GPS akan mengalami delay ketika melewati lapisan ionosfer kira-kira 300 km dari permukaan bumi. Variasi ionosfer diamati pada saat terjadi time-delay ini, sehingga didapat nilai TEC dimana I TECU sama dengan 1016 elektron/m2. Nilai tersebut yang akan menggambarkan besaran gangguan akibat adanya gempa. Pada penelitian ini mengamati perubahan ionosfer pada saat gempa dengan kedalaman dan magnitude yang berbeda. Studi kasus pertama magnitude berbeda dengan kedalaman yang sama dan studi kasus kedua kedalaman yang sama dengan magnitude yang berbeda. Berdasarkan penelitina yang telah dilakukan, disimpulkan bahwa perubahan ionosfer dipengaruhi oleh kedalaman dan magnitude gempa.

Abstract

Cromileptes Altivelis is one kind of exported fish commodities which are common in some areas of Indonesia. It cultured using Keramba Jaring Apung (KJA). Lampung Bay is one of the waters area that have potential as a location for the cultivation of those fishs. Determination of location for Cromileptes Altivelis aquaculture activities has strongly influenced by the quality of water because it affects the metabolism of fish growth. Described in the Standar Nasional Indonesia (SNI) 6487.4:2011 on Enlargement Production Cromileptes Altivelis in Keramba Jaring Apung (KJA) where the salinity, sea surface temperature, and pH are the important parameters that can affect the quality of sea water. In this research, the method that used to determine the location of CromileptesAltivelis aquaculture was remote sensing using Landsat-8 satellite imagery. This was because the Landsat-8 could work at visible wave (visible spectrum) where there are channels that can be used to extract quality parameters of ocean water. In determining the concentration of sea water quality parameters, this research used Son, et al algorithm and Syariz, et al algorithm to determine the value of salinity and sea surface temperature.Condition of water quality parameters in the Bay of Lampung was quite in accordance with the limit values listed in SNI 6487.4:2011 to be location of CromileptesAltivelis. Dominance value of sea surface temperature distribution was 26.05-30.05 C, dominance value of salinity distribution was 31.40-39.25 psu, and dominance value of pH distribution was 7.00–13.99. Based on the analysis of sea water quality parameters in Lampung Bay, territorial waters obtained 85.171,76 ha area corresponding to the location of Cromileptes Altivelis aquaculture.
