Abstract

Berdasarkan data yang dirilis Kementerian Dalam Negeri, Kalurahan Kaliagung masuk ke dalam kategori Desa Ektrem Miskin di Kulon Progo. Salah satu penyebabnya adalah kekayaan asli desa yang belum dikelola dengan baik. Dalam rangka mendukung pengelolaan kekayaan dan aset desa secara lebih integratif, maka diperlukan data dasar yang berkualitas. Salah satu data dasar yang dibutuhkan berupa peta dasar yang menggambarkan Kalurahan Kaliagung secara detail dan utuh. Peta dasar adalah salah satu dari Informasi Geospasial Dasar, yaitu penyajian lokasi geografis, dimensi atau ukuran, dan/atau karakteristik objek alam dan/atau buatan manusia di permukaan bumi pada skala dan sistem proyeksi tertentu yang berguna untuk alat bantu dalam pengambilan keputusan terkait ruang kebumian (Pasal 1 UU No. 4 tahun 2011). Pada pembuatan peta dasar Kalurahan Kaliagung, teknologi yang digunakan adalah pemotretan udara menggunakan wahana terbang nir-awak. Jenis wahana terbang yang digunakan adalah Vertical Take Off and Landing (VTOL). Pengukuran GCP dan ICP dilakukan dengan survei GNSS metode jaring. Hasil dari kegiatan ini berupa peta dasar dengan skala 1:6000. Data yang disajikan berupa foto udara, jaringan jalan, fasilitas umum, serta batas wilayah Kalurahan Kaliagung. Hasil pengujian menunjukkan peta dasar Kalurahan Kaliagung berada pada kelas 1 untuk ketelitian horizontal dan vertikal. Dengan demikian, peta dasar yang dihasilkan telah memenuhi regulasi yang berlaku (Peraturan BIG No. 18 Tahun 2021) sehingga dapat digunakan untuk analisis lanjutan.

Abstract

Prambanan Temple was built on an unstable soil structure—a layer of sandy soil with medium density. While on the west side, there are faults in the Opak River which could affect the stability of Prambanan Temple. Due to those situations, periodic monitoring of geometric aspects is necessary. This research has succeeded in defining X, Y, Z and φ, λ, h coordinates of Monitoring Points based on GPS observations which was post-processed using GAMIT/GLOBK software. The orthometric height (H) of all Monitoring Points had been obtained from the height difference survey tied to the TTG-852 reference point and calculated using the least square adjustment method. The position of Prambanan Temple was obtained by measuring the reflector mounted on the body of the temple using resection method. The results could be used as reference points in monitoring deformation in the following years.

Abstract

Batas daerah antara Kota Yogyakarta dan Kabupaten Sleman telah ditetapkan dan ditegaskan dalam Peranturan Menteri Dalam Negeri No 72 Tahun 2007, selanjutnya disebut sebagai Permendagri No 72/2007. Permendagri ini mengatur tentang batas daerah Kota Yogyakarta dan kabupaten Sleman dalam rangkaian koordinat titik pilar. Dalam batas daerah antara Kota Yogyakarta dan Kabupaten Sleman, terdapat 66 pilar batas yang terdiri dari tiga jenis pilar batas. Ketiga jenis pilar tersebut yaitu Pilar Acuan Batas Utama (PABU), Pilar Batas Utama (PBU), dan Pilar Batas (PBA). Telah dilakukan pengamatan secara visual terhadap 66 pilar batas yang berada di sepanjang garis batas Kota Yogyakarta dan Kabupaten Sleman. Artikel ini bermaksud untuk menyajikan hasil pengamatan secara visual pada pilar batas sebagai penanda (acuan) batas antara Kota Yogyakarta dan Kabupaten Sleman dengan tujuan untuk membantu pihak yang berkepentingan, dalam hal ini Pemerintah Kota Yogyakarta, dan Pemerintah Kabupaten Sleman dalam pemeliharaan batas antara kedua daerah. Dari hasil pengamatan secara visual ini didapati beberapa hal yang kedepannya perlu menjadi perhatian semua pihak yang berkepentingan terhadap batas ini, antara lain adanya pilar batas yang hilang, pilar batas yang sudah rusak, pilar batas yang terhalang tajuk, dan bermacam kondisi lainnya. Namun demikian masih terdapat juga pilar batas yang kondisinya cukup terawat dengan baik.The regional boundary between Yogyakarta City and Sleman Regency has been defined and confirmed in the Regulation of the Minister of Home Affairs No 72/2007, hereinafter referred to as Permendagri No 72/2007. This Permendagri regulates the regional boundaries of Yogyakarta City and Sleman Regency in terms of coordinating pillar points. Within the regional boundary between Yogyakarta City and Sleman Regency, 66 boundary pillars are consisting of three types of boundary pillars. The three types of pillars are the Main Boundary Reference Pillar (PABU), the Main Boundary Pillar (PBU), and the Boundary Pillar (PBA). Visual observations have been made to the 66 boundary pillars along the boundary lines of Yogyakarta City and Sleman Regency. This article intends to present a visual observation of the boundary pillar as a marker (reference) for the boundary between Yogyakarta City and Sleman Regency to assist interested parties, in this case, the Yogyakarta City Government and the Sleman Regency Government in maintaining the boundary between the two regions. From the results of this visual observation, several things need to be the attention of all parties with an interest in this limit, including missing boundary pillars, damaged boundary pillars, boundary pillars that are blocked by the canopy, and various other conditions. However, there are also boundary pillars that are in a quite good condition.

Abstract

Global Navigation Satellite Systems (GNSS) technology continues to develop, including in terms of supporting infrastructure development. One of the latest infrastructure developments is the establishment of the GMU2 Continuous Operating Reference Systems (CORS) station on October 14, 2023, the result of cooperation between DTK Vocational School UGM and PT Kantara Group. This applicative activity aims to test the accuracy of GNSS measurements using static and RTK-NTRIP methods with the CORS GMU2 reference and compare it with CORS JOGS in Yogyakarta. GNSS data was obtained from nine measurement points using static and RTK-NTRIP methods with CORS GMU2 and JOGS as reference stations. The static method refers to the SNI standard Horizontal Control Net with a recording interval of 15 seconds for 20 minutes, while RTK-NTRIP uses real-time correction via the internet. Analysis was conducted through the calculation of standard deviation, RMSE, and significance test of coordinate differences. The results show that the static method with the GMU2 reference produces standard deviations of the Easting component of 0.03 cm to 0.09 cm, Northing of 0.02 cm to 0.09 cm, and height of 0.05 cm to 0.17 cm. The RTK-NTRIP method produces standard deviations of the Easting component of 0.12 cm to 4.46 cm, Northing of 0.11 cm to 5.00 cm, and height of 0.21 cm to 6.77 cm. Although the precision of GMU2 CORS is quite good, its accuracy is lower than that of JOGS CORS, with significant differences at some points. The total RMSE for the static method reached 37.565 cm, while the RTK-NTRIP method ranged from 41.010 cm to 42.572 cm. Significance tests showed significant differences at most points, with null hypothesis rejection of 100% for the static method and 78 to 81% for RTK-NTRIP. In conclusion, further evaluation is needed to ensure the reliability of GMU2 CORS as a reference station.

Abstract

Every coastal state holds sovereign rights over the continental shelf that can go beyond 200 nautical miles (M) measured from baselines. This is commonly known as an extended continental shelf (ECS). However, these rights of ECS must be scientifically proven by meeting specific criteria governed by Article 76 of the United Nations Convention on the Law of the Sea (UNCLOS) 1982. Scientific survey activities play a crucial role in meeting such criteria. The results of these surveys are then submitted to the United Nations Commission of the Limits of the Continental Shelf (UN-CLCS) for review. To date, 95 applications for ECS have been submitted. This article comprehensively analyzes 34 applications, providing insights into the criteria for submitting applications for ECS and highlighting the significance and impact of the coastal state's scientific survey activities.
