Abstract

Keberadaan Waduk Sermo di Kabupaten Kulonprogo, sangat penting karena manfaatnya sebagai tampungan air bersih, sarana pariwisata dan saluran irigasi untuk lahan pertanian di sekitarnya. Namun demikian banyak juga yang tidak menyadari bahwa di bawah Waduk Sermo terdapat segmen sesar aktif yang memanjang dari Parangtritis ke Kulonprogo. Penelitian ini bermaksud untuk mengembangkan jaring pengamatan yang telah ada sebelumnya menjadi lebih luas cakupannya untuk mengetahui dampak dari adanya sesar aktif tersebut. Penelitian dilaksanakan dengan beberapa tahapan, yaitu: 1) pengembangan kerangka kontrol, dengan menambah tujuh titik (5 makro dan 2 mikro) jaring kontrol baru; 2) pengukuran kerangka kontrol, dengan menggunakan pengamatan GPS/GNSS metode relatif statik di semua titik kontrol sejumlah 15 titik; 3) pengolahan data, dengan menggunakan perangkat lunak GAMIT/GLOBK dan diolah dalam dua skenario terkait penggunaan titik referensi dalam pengolahan. Hasil dari penelitian ini adalah terbangunnya pilar/patok jaring pemantauan baru sebagai pengembangan jaring kontrol pemantauan Waduk Sermo, serta koordinat jaring kontrol hasil olahan dalam dua skenario, yaitu: pada skenario pertama, titik makro memiliki simpangan baku terkecil yaitu 0,004 m pada sumbu Z di titik MAK2. Sedangkan pada titik mikro, simpangan baku terkecil sebesar 0,004 m pada sumbu Z di titik BBR1 dan BMS2. Pada skenario kedua, simpangan baku titik makro terkecil yaitu 0,001 m pada sumbu X di titik MAK1. Sedangkan pada titik mikro, simpangan baku terkecil sebesar 0,005 m pada sumbu Z di titik BMS2. Titik-titik yang sudah dibangun dapat bermanfaat untuk memantau pergerakan bendungan dan secara berkala bisa digunakan untuk memantau aktivitas sesar yang berada di bawah Waduk Sermo.Kata kunci: pengembangan JKG, pemantau Waduk Sermo, teknik GPS/GNSS

Abstract

The availability of spatial information in 3D in a city that will apply the smart city concept is minimal or even non-existent. This makes the information conveyed less clear and less accurate. 3D map presentation is an indispensable component in the visualization of smart cities. The acquisition of spatial information in 3D can use several methods, one of which is the LiDAR (Light Detection and Ranging) drone. The Drone LiDAR is one of the new technologies in mapping surveys. Initially, LiDAR technology used a manned aircraft and had very large dimensions. Technological developments have made LiDAR portable using drones. Data acquisition was carried out using a multirotor-type Drone LiDAR from microdrones with a flying height of 60 meters above the ground. An area of ​​6 hectares in the Bulaksumur UGM area is the object of research for the 3D city model building. The objects mapped would range from one-story to five-story buildings. The results of data acquisition in the form of a point cloud are then modeled into a 3D building with the micro station software plugin Terra Solid and Terra Model. Modeling is done using automatic and manual methods. The results obtained are in the form of a 3D city model with a LOD 2 level of detail. The amount of vegetation in the mapped area makes the point cloud detail on the front side of the building less dense. However, the accuracy obtained is quite high, ranging from 0,4 to 5,1 cm, making it suitable for making 3D city models with LOD 2 detailed specifications.

Abstract

Monitoring of deformation on Sermo Dam has been widely practiced. One of them is by installing the monitoring point, locate dinside the Sermo Dam area called the micro network, and outside the dam called macro network. The installation of the micro network monitoring point aims to monitor the deformation of the dam due to the volume of water. The macro network monitoring point aims to monitor the effect of the existence of an active fault under the dam. In the last few years, monitoring in Sermo Dam has been done using GNSS technology. This paper intends to present the results of the accuracy represented by the deviation standard value of the measurement point at the macro net on the GNSS observation in 2016 and 2017. The objective is to compare the accuracy resulting from various GNSS processing strategies in observation 2016 and 2017, evaluation of GNSS measurements that can be used as guidance in subsequent GNSS measurements. The result shows that GNSS measurement in 2017 using two IGS reference points (BAKO and COCO) has a better standard deviation value compared to the 2016 measurement by the difference 1-5 mm on the X axis, 1-9 mm on the Y axis, and 1-2 mm on the Z axis. In the GNSS data processing using seven IGS reference points (BAKO, COCO, KARR, DARW, GUUG, PIMO, SHAO) in 2016 mostly has a better standard deviation compared to 2017 measurement except in MAK5 with the difference 0-4 mm on the X axis, 1-10 mm on Y axis, and 0-2 mm on Z axis. As for the value of coordinate data processing in 2016 and 2017on the two processing strategies there are differences in coordinate values that indicate the movement of monitoring points of macro network. However, the vector of the point movement that occurs in the two strategies has a different direction. This requires verification in-depth research and focused on the deformation of the Sermo Dam monitoring point.

Abstract

ABSTRAK Kelurahan Wates merupakan sebuah kelurahan yang berada di Kecamatan Wates, Kabupaten Kulon Progo. Pada awal bedirinya Kelurahan Wates ini berbentuk desa, dimana seluruh asset menjadi milik desa dan digunakan seluasnya untuk kemakmuran dan kesejahteraan warga Desa Wates. Pada tanggal 1 Desember 2010 status Desa Wates berubah menjadi Kelurahan Wates. Kelurahan Wates merupakan pusat pemerintahan Kabupaten Kulon Progo, sehingga secara tidak langsung aktivitas kelurahan berpengaruh terhadap kelangsungan Pemerintahan Kabupaten Kulon Progo karena terbatasnya anggaran, beberapa aspek dasar dalam hal data geospasial juga tidak muncul di dalam Renja 2017. Sebagai contoh belum adanya rencana kegiatan dalam hal pemetaan desa/kelurahan. Sehingga hal ini bisa menjadi peluang bagi perguruan tinggi untuk melaksanakan kegiatan penelitian dan pengabdian kepada masyarakat, khususnya dalam penyediaan data geospasial. Dari pemaparan permasalahan di atas, dimana yang menjadi pokok permasalahan adalah ketiadaan data geospasial, maka dapat diberikan solusi dengan pengadaan salah satu bentuk data geospasial, yaitu Peta Foto Udara Kelurahan Wates skala besar, yaitu antara 1:1000 – 1:5000. luaran dari pengabdian ini, yaitu berupa Peta Foto Udara Kelurahan Wates skala besar. Dari peta foto yang akan dihasilkan ini, nantinya dapat dikembangkan untuk membuat peta-peta turunan lainnya, seperti peta sarana-prasarana, peta jaringan jalan, dan sistem informasi desa yang direncanakan akan dibuat dalam pengabdian masyarakat pada tahun-tahun berikutnya. Kata Kunci: peta foto, foto udara, Wates, geospasial ABSTRACT Kelurahan Wates located in Wates District, Kulon Progo Regency. In the beginning, the Kelurahan Wates Wates was in the form of a village, where all assets belonged to the village and the company to the Wates community and village. On December 1st, 2010, the status of Wates Village changed to Kelurahan Wates. Wates Subdistrict is the center of Kulon Progo Regency government, indirectly for the kelurahan that is related to Kulon Progo Regency Government due to limited budgets, some things in the geospatial data will not appear in Renja 2017. For example, there are no planned activities regarding village / kelurahan mapping. Thus, this can be an opportunity for universities to carry out research and community service activities, especially in the availability of geospatial data. From the presentation of the problem, the main thing is the absence of geospatial data, and it can be provided with one form of geospatial data, namely the large-scale Wates Urban Air Photo Map, which is between 1: 1000-1: 5000. The output from this service, in the form of Large-scale Wates Urban Air Photo Map. From the maps that will be produced, it can be developed to make other derivative maps, such as facilities and infrastructure maps, road network maps, and village information systems that will be created in community service in the following years.. Keywords: aerial map, aerial photograph, Wates, Geospatial

Abstract

Since 1991, Prambanan Temple has been recognized by UNESCO as a cultural heritage of a historic building. In its construction, the Prambanan temple was established in a labile soil structure in the sandy soil and not far from the Opak River. In the geological map of Yogyakarta, there is a fault under the Opak River landscape. This fault under the Opak River has caused an earthquake in 2006. Because of its position in disaster-prone areas, regular monitoring of the geometric aspects of Prambanan Temple is very necessary.This research aims to build a deformation monitoring control point in Prambanan Temple. Eight control points, consist of three existing points and five new points are built around Prambanan Temple. These eight control points then were measured by observing GNSS for 1x24 hours in order to define their coordinates. GNSS data processing is done using GAMIT 10.70 software with two strategies, namely (1) processing with regional binding points, in this case using IGS BAKO and JOG2 stations, and (2) processing with global binding points using IGS COCO station reference points, DARW, KARR, POHN, PIMO, DGAR, and IISC. This research yields the establishment of Prambanan temple deformation control points and their coordinates and standard deviation in two processing strategies. The smallest standard deviation in the first strategy is 0.0787 m on the Z-axis for points of PRO1 and PR03. The biggest standard deviation is 0.1218 m on the Y-axis at point of PR02. In the second strategy the smallest standard deviation is 0.0036 m on the Z-axis for points of PR01 and PR03. The biggest standard is 0.0141 m on the Y-axis at point of PR02.
