Abstract

The subject of the  investigation reported in this paper is  the visualization of three-dimensional (3D) surface models in a 3D mapping survey using terrestrial laser scanning (TLS). The Cangkuang Temple nearby Garut City was chosen as the object. The laser technology instruments used were a Topcon GLS-1000 (Geodetic Laser Scanner) and a Topcon IS (Image Station). Twelve points at  the same position in each 3D surface model  were selected.  The coordinate system of the IS was then transformed into the coordinate system of the GLS-1000 using a 3D similarity transformation model. The 3D distances were calculated for each model.  Differences  in distance were considered as errors  in the x, y,  and z  direction.  The standard deviation of the  distance differences was ±0.301 m. Some of the distance differences did not fall within the range of tolerances (about 15%). The 3D surface model visualization of the Cangkuang Temple that was created from the GLS-1000 data was more precise than the one created from the IS data. In the future, such 3D surface model visualizations could be used for documentation, preservation and reconstruction of heritage buildings.

Abstract

Abstract. Indonesia as an archipelagic country has marine area larger than land area, 13.446 islands (Geospatial Information Agency, 2012) with coastline 95,181 km (Indonesian Maritime Council, 2008), making Indonesia has natural resources of the sea more than the natural resources on land. This potential conditions of marine resources is seen as an opportunity for Indonesia as a developing country to build excellence in coastal and marine field. But during 68 years of the nations independence, maritime sector has notproved as a sector that can be seeded by the nation and relied by Indonesian people. Based on the literature, one of the main problems in Indonesian ocean is marine boundariesdetermination are unclear and unresolved causes uncontrolled human intervention in managing marine resources and chaotic patterns of use of marine resources, uncontrolled utilization even destructive.  This paper discusses about marine boundaries problems that is happened in Indonesia whether they arise from the country and from abroad. Until now much of Indonesia marine boundaries with neighboring countries are still unfinished. Implementation of UUD1945 Article 18 and 25 junctoLaw No.32/2004 juncto Regulation of the ministry of home affairs No. 1/2006 about determination and demarcation of boundaries (including marine boundary) hasn’trealized. There is no certaintboundaries of exploitation and utilization activities in ocean spacebyinstitutional (sector), nor implementation of marine management in eastern Indonesia that more often faced with the existence of customary marine management caused overlapping claims marine areas that can raisemarine boundariesconflicts between regions, sectors or customary.  In general, marine cadastre deals with how states define, organize and manage marine boundaries in their countries. This condition causes marine cadastre concepts in continental countries such as America, Canada, and Australia can not be fully implemented in Indonesia. Marine cadastre concept for Indonesia should adopt the archipelago needs, in the context associated with UNCLOS82, Law No. 32 2004 about regional autonomy, Law No.27 2007 about coastal management areas and small islands, and customary marine authority. This paper is part of dissertation research in order to build model of marine cadastre system uses evaluation definition approach and geospatial information principles.  Keywords: Marine Boundaries, Marine Cadastre, Archipelagic Perspective

Abstract

Penilaian tanah menjadi salah satu aspek dalam sistem kadaster yang terintegrasi dengan penggunaan tanah dan penguasaan tanah. Tanah dapat dinilai atas dasar manfaat yang bisa diberikan. Tinggi rendahnya nilai tanah dipengaruhi oleh banyak faktor, di antaranya faktor ekonomi, sosial, pemerintah, dan fisik. Berdasarkan faktor yang dapat menentukan nilai tanah tersebut, diketahui bahwa penggunaan tanah dapat pula berpengaruh terhadap pembentukan nilai tanah. Beberapa penelitian telah menyatakan bahwa tata guna lahan merupakan faktor yang paling dominan pengaruhnya terhadap nilai tanah. Pada penelitian ini digunakan analisis geostatistika yang diterapkan dalam pemodelan nilai tanah. Perhitungan estimasi nilai tanah dilakukan dengan menggunakan model spherical, exponential, maupun gaussian. hasil penelitian menunjukkan bahwa model semivariogram terbaik berdasarkan perhitungan adalah model gaussian, karena memiliki besaran standar deviasi terendah bila dibandingkan dengan standar deviasi yang dihasilkan oleh model exponential dan spherical. Model matematika nilai tanah hasil analisis geostatistika akan dimodifikasi dengan memasukkan bobot tata ruang. Model matematika nilai tanah hasil modifikasi ini diharapkan dapat mencerminkan nilai yang sebenarnya, di mana selanjutnya dapat dipergunakan dalam pembuatan pembuatan zona nilai tanah.
