Abstract

Abstract. Two important things in the scope of Geodesy and Geomatics engineering and geodetic science is positioning and coordinates. The position is defined simply as the existence of an object to other objects , while the coordinate is defined as a position statement quantitatively , or others mentioned in the definition of the coordinates is a quantity (numerical) to declare the location or position of a point (object) in a chamber (field) . To ensure consistency and standardization of a coordinate , which applies to the local system to the global (world) , it is necessary to declare the existence of a coordinate system . This system is called the coordinates reference system or Geodetic Reference System , with elements of a constituent or parameter consist of Reference Frame and coordinates Reference System on the earth's static system , and the reference system , coordinates and Datum Reference Frame coordinates on the earth's dynamic systems . Datum Coordinates further divided into several types of Datum Static, Semi Dynamic , Dynamic , Semi Kinematic and Kinematic .What Geodetic Reference System which is generally used in the global scope ( the world ) will be discussed in this paper . Hope this theme can be one basis when we as a community of Geodesy and Geomatics , or even national community select or determine what the true Geodetic Reference System . This paper will also discuss specifically Geodetic Reference System in several countries . Keywords : Positioning, Coordinate, Geodetic Reference System, Coordinate Datum

Abstract

Abstract. In each GPS time series data, there are signals which exist and affect the result that has been received, which is called noise. Those noise components will form certain pattern in time series. Basically, time series has periodic component which commonly not being able to be detected directly. To detect which periodic component that dominantly affect the time series, there is a way which is called spectral analysis. With acknowledge periodic component in a time series, we can know the characteristic of the time series and then we can determine how many parameters will be needed to do curve fitting. There are two approximations in fitting, it is either linear fitting only or linear fitting with including periodic component. As a comparison between these two methods, we need to be estimate displacements velocity rate in a year. From the analysis that has been done, the result is that the biggest difference of displacements velocity rate between these two methods is 3.7 milimeters per year.Keywords: displacements velocity rate, fitting, periodic component, spectral analysis, time series.

Abstract

Abstract. Sumatra is located near the place where the collision between Indo-Australian Plate and Eurasian Plate heppened. When Indo-Australian Plate moves below Eurasian Plate, the friction that occur between both plates causes the strain is being accumulated. The strain that exceeds the elastic limit will be released as an earthquake. GPS observation in Sumatra was conducted to analyse the velocity of vector displacement and the heterogenous of tectonic strain on the surface as one of the tectonic indication to earthquake mitigation in the future. The result from data processing shows vector displacement in Sumatra has northeast direction that indicate inter-seismic and southwest direction that indicate post-seismic. The strain distribution is extension that indicate post-seismic equally scatteres dominantly in zone where happened Aceh earthquake on 2004, Nias earthquake on 2005, Bengkulu on Sptember 12th 2007, and earthquake on Mentawai Island on September 13th 2007. While strain as compression shows Sumatera still has inter-seismic effect.Keywords: compression, earthquake, extension, GPS.

Abstract

We reexamined GPS stations in Eastern part of java to understand the recent deformation from the convergence zone between the Australian Plate and Sunda Block in East Java. From the seismic record in the subduction zone shown the occurrence of tsunami earthquake in M7.7 in 1994 and several number of earthquakes that potentially become tsunami. To comprehensively obtain the signal in subduction zone, we have to remove the effect of the other major sources deformation in the area of study, as in this study is the block motion from Sunda Block. To remove the block motion of Sunda Block we used the parameters of the model Altamimi (2007) in the GPS field. The used data for this research is several campaign GPS and Continuously GPS data from 2010 "“ 2016. These data processed using GAMIT/GLOBK 10.6 software to obtain geocentric coordinates, geodetic coordinates, and standard deviation which reference to ITRF2000. Geocentric coordinates are transformed into topocentric coordinates to know the rate of shift vector speed. From the obtained displacement rate, carried reduction to clean up from other deformation source. The value of surface deformation is made as input for the inversion calculation from dislocation theory in half space by Okada (1992). The result show the strong slip distribution in the two sides of fault model that located near the costal of Pacitan and the in the south of Banyuwangi, this slip distribution represent the coupling from the convergence zone. It indicates there are accumulating energy due to convergence of the megathrust. The comparison of surface deforomation from forward calculation and the GPS observation are nearly similar which indicated by the value of rms residual is ± 2.06 mm. However from the model accuracy and resolution found that model contain misfit in dependent location. From this research, we highlight the value of slip distribution correlating to the risk assessment in Java Island.

Abstract

Continuous  Global  Positioning  System  (GPS)  observations  showed significant  crustal  displacements  as  a  result  of  the  Bengkulu  earthquake occurring on September 12, 2007. A maximum horizontal displacement of 2.11 m was observed at PRKB station, while the vertical component at BSAT station was lifted up with a maximum of 0.73 m, and the vertical component at LAIS station had subsided  "“0.97 m. Adding more constraints on the inversion for the Bengkulu earthquake slip distribution inferred from GPS observations can help solve  the  underdetermined  least-squares  inversion.  Checkerboard  tests  were performed  to  help  conduct  the  weighting  for  constraining  the  inversion.  The inversion calculation yielded an optimal value for the slip distribution by giving the smoothing constraint a weight of 0.001 and the slip constraint a weight of = 0 at the edge of the earthquake rupture area. The maximum co-seismic slip of the optimal inversion calculation was 5.12 m at the lower area of PRKB station and BSAT station. The seismic moment calculated from the optimal slip distribution was 7.14 x 1021 Nm, which is equivalent to a magnitude of 8.5.

Abstract

Papandayan is an A-type active volcano located in the southern part of Garut Regency, about 70 km southeast of Bandung, Indonesia. Its earliest recorded eruption, and most violent and devastating outburst occurred in 1772 and the latest eruptions occurred in the period of 11 November to 8 December 2002, and consisted of freatic, freatomagmatic and magmatic types of eruption.During the latest eruption period, GPS surveys were conducted at several points inside and around the crater in a radial mode using the reference point located at Papandayan observatory around 10 km from the crater. At the points closest to the erupting craters, GPS displacements up to a few dm were detected, whereas at the points outside the crater, the displacements were in the cm level. The magnitude of displacements observed at each point also show a temporal variation according to the eruption characteristics. The results show that deformation during eruption tends to be local, e.g. just around the crater. Pressure source is difficult to be properly modeled from GPS results, due to limited GPS data available and differences in topography, geological structure and/or rheology related to each GPS station.

Abstract

Topography of a volcano crater can change due to endogenic processes such as deformation or eruption, or surface processes. Erosion and deposition are surface processes that may occur and gradually change the slope of the inner volcano crater. Here, we investigated erosion and deposition processes that occurred in the Kelud crater after the 2014 plinian eruption. We used high-resolution Digital Elevation Models (DEMs) and orthomosaic images derived by drone photogrammetry that acquired between September 2018 and July 2019. We obtained hundreds of aerial images which were reconstructed to obtain 3D models of Kelud’s crater by using Structure from Motion (SfM) technique. Results show erosions at alluvial fans that dominantly located at the east valleys of Kelud crater. The erosion removed the volcanic materials up to -5 m which transported and deposited close to the vicinity of the Kelud crater. The deposition process causes the increase of the Kelud crater lake up to 3 m. Moreover, we also mapped the thermal distribution of the Kelud crater lake by using low cost thermal camera. Our thermal investigation is able to identify some hotspots at the vicinity of the Kelud crater lake with range temperature of 43.7°C – 55.3°C, while the average apparent temperature of the Kelud crater lake is ~ 29°C. This high temperature area may indicate underwater active fractures that continuously release volcanic gasses which leads to convection heat transfer through Kelud’s water lake.

Abstract

Kabupaten Bandung merupakan sebuah kabupaten di Provinsi Jawa Barat, Indonesia yang rutin mengalami bencana banjir setiap tahunnya, sehingga warga yang terdampak banjir harus mengungsi. Salah satu upaya yang dilakukan pemerintah untuk memperkecil dampak banjir di Daerah Aliran Sungai (DAS) Citarum khususnya di Kabupaten Bandung adalah dengan rencana memindahkan penduduk ke tempat lain, namun sebagian masyarakat menolak adanya rencana relokasi sebagai upaya menanggulangi bencana banjir. Penelitian ini bertujuan untuk memperoleh lokasi pengungsian sesuai dengan kriteria yang telah ditentukan dan dibobot menggunakan metode AHP. Metode AHP merupakan suatu metode pendukung dalam pengambilan sebuah keputusan yang dapat mengurangi masalah multi kriteria yang rumit menjadi suatu hirarki. Dalam metode AHP permasalahan yang rumit dapat diuraikan ke dalam beberapa kelompok dan diatur menjadi suatu bentuk hirarki sederhana sehingga permasalahan yang ada menjadi lebih sistematis dan terstruktur. Penelitian ini menggunakan 9 kriteria yang diambil dari beberapa pertimbangan sesuai dengan karakteristik wilayah Kabupaten Bandung yaitu jarak dari sumber air, jarak dari lokasi bencana, jarak dari fasilitas kesehatan, kemiringan lereng, jarak dari ancaman longsor, jenis tutupan lahan, aksesibilitas, luas lokasi, dan hak atas tanah. Hasil penelitian ini menunjukkan bahwa kriteria jarak dari sumber air memiliki bobot tertinggi yaitu 20% berdasarkan hasil penilaian oleh responden. Lokasi dengan kesesuaian lahan tinggi untuk lokasi pengungsian terletak di Kecamatan Cileunyi, Ibun, Majalaya, Margaasih, Margahayu, Pacet, Rancaekek, Soreang, Kertasari, Pengalengan dan Rancabali.

Abstract

ABSTRAKTumbukan miring Lempeng Eurasia dengan Lempeng Indo-Australia membentuk zona subduksi di bagian barat Pulau Sumatra dan sejumlah segmen sesar di darat Pulau Sumatra. Zona subduksi dan segmen sesar yang terbentuk aktif bergerak sehingga sering menimbulkan gempa bumi di wilayah tersebut. Semenjak diberlakukannya Sistem Referensi Geospasial Indonesia 2013 (SRGI 2013) sebagai referensi tunggal dalam aktivitas pemetaan di Indonesia, maka perubahan posisi kerangka referensi koordinat sebagai fungsi waktu akibat dinamika bumi perlu diperhitungkan. Dengan terjadinya dua gempabumi yang berurutan pada tanggal 6 Maret 2007 di wilayah Danau Singkarak Sumatra Barat, akan menimbulkan deformasi koseismik yang dapat mempengaruhi SRGI2013. Dalam penelitian ini dilakukan analisis untuk menentukan model koseismik gempabumi Sianok yang paling sesuai dan sejauh mana dampaknya pada SRGI 2013. Berdasarkan hasil analisis terhadap nilai residual hasil validasi dengan koseismik pada 11 titik pengamatan GPS dapat disimpulkan bahwa model koseismik dari gempabumi Sianok adalah model koseismik menggunakan data parameter gempa dari Global CMT dengan residual misfit 47.5 mm. Secara umum, pola kosesimik gempabumi Sianok mendeskripsikan mekanisme gempabumi sesar geser. Nilai kosesimik terbesar terjadi pada titik KACA dan K108, yaitu 135,43 mm dan 84,74 mm. Besarnya koseismik gempabumi Sianok tidak berpengaruh terhadap peta dengan skala 1: 1000, akan tetapi akan mempengaruhi nilai koordinat Jaring Kontrol Geodesi (JKG) yang berada di sekitar daerah gempa, sehingga perlu adanya pemutakhiran koordinat dari JKG.Kata kunci: Gempabumi Sianok, GPS, Deformasi Koseismik, SRGI2013. ABSTRACTThe oblique movement of Eurasian Plate towards Indo-Australian Plate create subduction zone in the western part of Sumatra Island and some faults on the mainland of Sumatra. These subduction zone and faults actively produce some earthquakes. Since we used the Geospatial Reference System of Indonesia 2013 (SRGI 2013) as one reference on mapping activities in Indonesia, coordinate changes as a function of time caused by earthquake cycle need to be calculated. There are two earthquakes that had been occurred on March 6, 2007 in Singkarak Lake area which affected the SRGI 2013. We analyzed the data to estimate the coseismic model of Sianok earthquake and the impact to the SRGI 2013. The residual from the coseismic model by including 11 GPS displacements shows that the coseismic model of Sianok earthquake is a model that used earthquake parameters from Global CMT with the misfit of 47.5 mm. Overall, this coseismic pattern shows the shear mechanism. The largest displacements are on KACA and K108 sites, that are 135.43 mm and 84.74 mm respectively. The coseimic of Sianok earthquake does not affect a map with scale of 1:1000, but affect the Geodetic Control Network in this area. From this analysis, we conclude that we need to update our Geodetic Control Network.Keywords: Sianok Earthquake, GPS, Coseismic Deformation, SRGI2013.

Abstract

Indonesia bagian barat terdiri dari Sunda Shelf (landas kontinen Asia Tenggara), yang meliputi pulau-pulau Sumatera, Jawa, Bali, Kalimantan, dan barat daya bagian dari Sulawesi. Sunda Shelf adalah bagian dari lempeng Eurasia yang luas, tetapi tabrakan dari India dengan Asia Tengah memungkinkan terjadinya gerakan yang signifikan dari Asia Tenggara dan Sunda Shelf relatif terhadap Eurasia. Selat Bali teletak diantara pulau Jawa dan Bali yang termasuk ke dalam blok Sunda. Blok Sunda meliputi Sumatra, Jawa, Bali, Kalimantan dan Sulawesi bagian barat [Hamillton, 1979]. Saat Lempeng Indo-Australia bergerak kebawah Lempeng Eurasia, terjadi kontak bidang antar lempeng sehingga terakumulasi regangan. Regangan yang telah melewati batas elastisitas akan dilepaskan sebagai gempa bumi. Namun demikian berdasarkan Journal of Geophysical Research tahun 2003 hasil penelitian Bock mengenai Crustal motion in Indonesia from Global Positioning System Measurements disebutkan bahwa regangan yang terjadi di Blok Sunda adalah kecil yaitu 5 x 10-8 per tahun. Berdasarkan hasil pengolahan data hasil pengamatan GNSS di Selat Bali menggunakan software Bernese versi 5 dapat diketahui bahwa Selat Bali mengalami pergeseran ke arah tenggara yang mengindikasikan adanya proses inter-seismic. Besar regangan (strain) yang terjadi di Selat Bali dihitung  menggunakan metode perhitungan regangan (strain) garis sehingga dapat di tentukan besar regangan antara ke dua titik pengamatan GNSS CORS yang digunakan pada penelitian ini.   Kata Kunci : Sunda Shelf, Selat Bali, Regangan (Strain), Pergeseran, Bernese
