Parcels data in Indonesia are still stored in 2-dimensional (2D) geometry which are integrated with other attribute data, such as the case with the Directorate of Land and Building Tax Indonesia. Whereas, building taxes assessment refers to a number of details that require the information to be stored in 3-dimensional (3D) forms. This study aims at the use of Building Information Modeling (BIM) technology, which widely used in building asset management in 3D. This research illustrates the usability of the role of BIM in assessing and managing building taxes in Indonesia. The point clouds were obtained using Terrestrial Laser Scanner (TLS) technology. The point clouds processed so that it can form 3-dimensional geometrical apartment. The attributes of the 3-dimensional model integrated with the geometric model using the BIM concept. The results analyzed to assess whether BIM concept was able to fulfill the needs of the 3D fiscal cadastre in Indonesia.
Building asset management is a system for organizing building assets in order to provide information to support decision making. One part of asset management is the inventory of building assets. Asset inventory can be done based on Building Information Modelling (BIM). BIM is one of the approaches to look at the building as a large unified database that can provide different information. The research case is theinventory of local government assets, especially state university assets because in Indonesia, state university assets belong to local government assets. The first step of local government asset inventory is to do three-dimensional modelling using a terrestrial laser scanner (TLS) assisted by Autodesk Revit. A textual database is created which contains the location code and item code on the asset referring to the Regulation of theMinister of the Home Affairs Number 108 Year 2016 on the Classification and Codification of Regional Property. The database is directly integrated with the threedimensional model of the building. By doing these two things, there will be a building asset management process that is integrated with BIM and can be used to plan assetdevelopment. ABSTRAK: Pengurusan aset bangunan adalah sistem untuk menganjurkan aset bangunan untuk memberikan maklumat untuk menyokong pengambilan keputusan. Satu bahagian pengurusan aset adalah inventori aset bangunan. Penyediaan aset boleh dilakukan berdasarkan Pemodelan Maklumat Bangunan (BIM). BIM adalah salah satu pendekatan untuk melihat bangunan sebagai pangkalan data bersatu yang besar yang dapat memberikan maklumat yang berbeza. Kes penyelidikan adalah untuk inventori aset kerajaan tempatan, terutamanya aset universiti negeri, kerana di Indonesia, aset universiti negeri adalah milik aset pemerintah daerah. Langkah pertama inventori aset kerajaan tempatan adalah melakukan pemodelan tiga dimensi menggunakan pengimbas laser bumi (TLS) yang dibantu oleh Autodesk Revit. Pangkalan data teks dicipta yangmengandungi kod lokasi dan kod item aset yang merujuk kepada Peraturan Menteri Dalam Negeri Nombor 108 Tahun 2016 tentang Klasifikasi dan Pengkodifikasi Harta Daerah. Pangkalan data secara langsung disepadukan dengan model tiga dimensi bangunan itu. Dengan melakukan dua perkara ini, akan membina proses pengurusan aset yang disatukan dengan BIM dan boleh digunakan untuk merancang pembangunan aset.
3D modeling of functional buildings is growing rapidly because of its excellence. 3D modeling can also be applied to heritage buildings, but it is still rarely done due to the variety of detail, and the unique shape of the objects in heritage buildings make it more difficult to be modeled. In consequence, an adequate instrument with different scanning densities is required in this case, namely Terrestrial Laser Scanner (TLS) and Handheld Laser Scanner (HLS). This study, conducted at Penataran Temple in Penglipuran Village, Bali, aims to analyze the registration result of point clouds acquired by TLS and HLS, as well as its capability to build the 3D model. Point cloud data is acquired using TLS and HLS tools, and the information about the object is obtained by doing interviews with the Chief of Penglipuran Village and the villagers. The point cloud that TLS acquires is registered with Iterative Closed Point (ICP) algorithm, while the point cloud of HLS is registered by using Helmert and Affine transformation method. Based on the results, the registration of HLS point cloud data to the TLS Affine method has better quality accuracy than the Helmert method. In addition, point cloud data scanned by HLS can present 3D models with a better Level of Detail (LOD) than point cloud data from TLS.
Sustainable development consists of the developing process of land, city, business, and community, which can be used for future generation. One of the tools for describing this process is called spatial planning. Spatial planning taking into account several aspects such as the number of plots (2D), vertical rooms or apartment (3D) of buildings and access to transport. The realization of this object requires the application of three-dimensional (3D) cadastre. This is essential for property rights to be registered and not superimposed. Traditionally, the cadastre is based on a representation of the 2D terrestrial division, but the 2D cadastre is not appropriate for applying and modelling information about the products. Some researchers have also discussed the options for transitioning 2D to 2D+ or three-dimensional (3D) registrations. According to Behnam et al (2016), the use of Building Information Model (BIM) as a feasible approach for managing land and property information in the administration of multi-storey buildings. Here, BIM is a technology capable of displaying the building's in 3D model which can provide any kind of information inside the building. In this research our focus on surveying and mapping the sustainable development of Balinese building structure based on their indigenous knowledge. From survey results, Bali has a unique building structure in land use terminology. Generally, Balinese people use the concept of Tri Hita Karana (relationship of God, Human and Environment) for building their home. Beside, in Bali, there is a local rule that the high of building has limitation of 15 meters or it should has 5 floors. Therefore, this will impact the development future infrastructures such as to build bridge, toll road, apartment, railway and etc. Thus the big challenge in this area is to sustain local culture but technology can be implemented.
