Citra SRTM digunakan untuk analisa morfologi bentang alam sedangkan pengukuran geolistrik bertujuan untuk mendapatkan gambaran litologi bawah permukaan tanah untuk mendapatkan potensi air tanah. Survei sebaran mata air dilakukan untuk menguatkan analisis data. Data SRTM menunjukkan morfologi bentang alam berupa dataran batugamping berundak mulai dari pantai di sisi Timur kearah Barat. Mata air ditemukan berada di kaki dataran berundak yang merupakan perpotongan topografi. Pengolahan data geolistrik menunjukkan bahwa susunan batuan bawah permukaan tanah daerah kajian terdiri dari batugamping terumbu yang merupakan anggota Formasi Kaliangga sebagai lapisan berpori pembawa air dan batupasir tufan anggota Formasi Kananggar sebagai lapisan kedap penahan air. Morfologi berupa perundakan batugamping di sebagian besar area kajian menjadikan keterdapatan mata air berada di kaki undak atau perpotongan topografi. Hal ini menguatkan dugaan bahwa air permukaan meresap kebawah menembus pori batugamping terumbu kemudian tertahan oleh batupasir tufan dan keluar sebagai mata air di perpotongan topografi. Hal ini konsisten dengan hasil pengukuran geolistrik yang menunjukkan dominasi batugamping terumbu di area kajian dan minimnya curah hujan menjadikan daerah kajian menjadi daerah kering.","PeriodicalId":190139,"journal":{"name":"Elipsoida : Jurnal Geodesi dan Geomatika","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122449766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jamal, Sonny Mawardi","doi":"10.14710/elipsoida.2020.9213","DOIUrl":"https://doi.org/10.14710/elipsoida.2020.9213","url":null,"abstract":"Terrestrial measurements can provide accurate gravity data, but it is costly and time-consuming for large and remote area. Airborne gravity measurements have actually been carried out in Indonesia since 2008 by Technical University of Denmark (DTU) in collaboration with the Geospatial Information Agency (BIG). Purpose of the project was to develop a geoid model used for converting elevations from GPS/GNSS measurements that refers to ellipsoid to orthometric elevations that refer to sea level. The data can actually be explored so that it can be used for geophysical and other geoscience purposes, but the data must be carefully treated and extracted into observational gravity data. This study aims to improve the accuracy of gravity airborne data to produce an accurate complete Bouguer anomaly map. The data used in this study were airborne gravity data over Province of Southeast Sulawesi collected on September 29, 2008 to October 1, 2008.  Variation in flight height at the time of consecutive data introduced new horizontal acceleration vector. It must be treated as a noise in the measurement of gravity data. The first stage of processing was to eliminate noise due to aircraft acceleration. Gravity data measured in aircraft conditions accelerating more than 5 m.s-2 were eliminated. In this stage, the gravity data were reduced from 64481 observation points to 4900 observation points. The second stage of processing was low pass filtering to eliminate the remaining surges in gravity data. Airborne gravity data that have been snooped and filtered were then applied to calculate the complete Bouguer anomaly. Visually, a complete Bouguer anomaly map through the enhancement process produced a finer map compared to maps from airborne gravity data without enhancement. Comparison of airborne Bouguer anomaly map and terrestrial Bouguer anomaly maps of Kendari sheet showed a correlation of more than 83%. The conclusion of this study was that the enhancement of the airborne data significantly increases the accuracy and reliability of the airborne gravity data for generating a complete bouguer anomaly map. The results of this study also indicated that the airborne archive data has the potential to be used for geophysical and geosciences purposes in Southeast Sulawesi and Indonesia.","PeriodicalId":190139,"journal":{"name":"Elipsoida : Jurnal Geodesi dan Geomatika","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123395176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Precursor detection of major earthquakes using TEC in the ionosphere has recently become a promising method. This paper focuses on investigating TEC inconsistencies before major earthquakes in the North Maluku region during 2019. Earthquake data refers to the U.S. Geological Survey, while the TEC data comes from GIM which comes from international GNSS. TEC anomaly was observed by applying the TEC correlation method near the epicenter of the earthquake to obtain the TEC inconsistency index. The TEC anomaly classification is decided when the inconsistency index is outside a defined threshold. The Dst index in the same time frame is used to analyze TEC inconsistencies due to geomagnetic storms. The results of research on the January 7, 2019 Mw 6.6 earthquake, the July, 7 2019 Mw 6.9 earthquake, the July 14, 2019 Mw 7.2 earthquake, and the November 14, 2019 Mw7.1 earthquake showed TEC inconsistency 29 to 1 day before the mainshock.

Sistem proyeksi ini bersifat konform yang mempertahankan bentuk (sudut) tetapi tidak mempertahankan luas dan jarak. Penelitian ini menghitung perbedaan luas pada beberapa sistem proyeksi dan sistem koordinat di batas pengelolaan wilayah laut Provinsi Jawa Tengah. Sistem proyeksi dan sistem koordinat yang digunakan adalah: Proyeksi Lambert Silinder Equal Area, Proyeksi UTM Zona 49 Selatan, Proyeksi Transverse Mercator dan Proyeksi Mercator dengan dua sistem koordinat yang berbeda. Selisih luas dihitung terhadap luas hasil proyeksi Lambert Silinder Equal Area yang mempertahankan luas pada sistem proyeksinya. Luas daerah pengelolaan wilayah laut Provinsi Jawa Tengah pada proyeksi UTM dan Transverse Mercator mempunyai persentasi selisih luas yang kecil jika dibandingkan dengan luas proyeksi Lambert Silinder Equal Area. Besarnya persentase selisih luas tidak signifikan sehingga penarikan batas pengelolaan wilayah laut Provinsi Jawa Tengah dapat dilakukan pada sistem proyeksi konform UTM. Perbedaan persentasi luas yang besar pada proyeksi Mercator dibandingkan dengan proyeksi UTM dan Transverse Mercator disebabkan letak daerah yang berjarak paling jauh pada garis yang mempunyai distorsi nol.Permendagri No. 141 of 2017 states that the regional boundary map including the maritime area management boundary map uses the Transverse Mercator projection system and the UTM coordinate system. This projection system is conform projection which maintains shape (angle) but does not maintain area and distance. This study calculates the area differences in several projection systems and coordinate in the management boundaries of the sea territory of The Central Java Province. The projection system and coordinate system used are: Equal Area Cylindrical Lambert Projection, UTM Projection zone 49 south, Transverse Mercator Projection and Mercator Projection with two different coordinate systems. The difference in area is calculated against the projected area of the Lambert Cylindrical Equal Area which maintains the area of the projection system. The area of the sea management area of Central Java Province in the UTM and Transverse Mercator projections has a small percentage difference in area when compared to the projected area of the Lambert Cylindrical Equal Area. The magnitude of the percentage difference in area is not significant so that the drawing of boundaries for the management of the sea area of Central Java Province can be carried out on the UTM conforming projection system. The bigger percentage of area difference of the Mercator projection compared to the UTM and Transverse Mercator projections is due to the location of the area that is the farthest away from the line which has zero distortion.","PeriodicalId":190139,"journal":{"name":"Elipsoida : Jurnal Geodesi dan Geomatika","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131944537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A decrease in coastal environment quality can be indicated by looking at the mangrove of quality plants. The Government of Pati Regency carries out regular mangrove planting to improve the quality of life in the coastal environment, but there is no supervision. This study uses remote sensing technology and GIS to determine the relationship between changes in mangrove plant density and changes in coastlines in Pati Regency from 2017 to 2020. This study uses remote sensing methods using the NDWI water index transformation method to determine the shoreline from Sentinel-2-year image. 2017-2020, MSL reduction using DEMNAS and MSL, then processed with a Geographical Information System using DSAS to obtain the results of shoreline changes (NSM) as well as guided classifications for land cover and vegetation indexes NDVI and GNDVI which are used to map mangrove vegetation density on the coast of the Pati Regency. The results showed that the average change in the coastline in Pati Regency has increased by 22,260 m. Changes in the area of mangroves on the coast of Pati Regency have increased by 86.634 hectares. The results also showed that the relationship between changes in mangrove density and shoreline changes on the coast of Pati Regency used simple linear regression with the coefficient of determination (R2) of 0,089 and the correlation coefficient (R) of 0,299. These results indicate a correlation enough. The calculation of the F test to determine changes in mangrove density with changes in shoreline has a significant effect, so that if the value of mangrove density is higher, changes in shoreline will tend to increase (accretion).","PeriodicalId":190139,"journal":{"name":"Elipsoida : Jurnal Geodesi dan Geomatika","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116996564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
