PURWARUPA PENERAPAN LADM (LAND ADMINISTRATION DOMAIN MODEL) UNTUK PELAYANAN KADASTER 3D/RUSUN DI INDONESI

Limitations of land supply for infrastructure development in urban areas led to the development of technology and vertical buildings implementation as an alternative to fulfill the need for space. Flats, apartments and plazas construction in big cities in Indonesia indicated that the need for space above the soil surface is increasing. Increasing the number of that buildings will cause the right management of ownership over the space problems, if not immediately followed up with the efficient and effective development of rights registration management systems. For the first step of the ownership management and the registration system of space (3D cadastre) which leads to an information system is by making a digital information system prototype. Basic class LADM identification with Law. No. 20, 2011 about the Flats and Perkaban BPN-RI No. 1, 2010 about Standard Services and Land Regulation is an alternative to construc of a 3D cadastre information system. This research uses 3D spatial data of Plasa Simpaglima building , Semarang in AutoCAD format. Enterprise Architect UML CASE Tools 9.3 trial version is used to create a spatial database schema design both conceptual, logical and physical implementation of the DDL. DBMS PostgreSQL with PostGIS spatial extensions is used to store attributes and spatial data. Delphi programming language is used to design the interface application that is easy for users with GLScene components for 3D spatial data visualization. This research succeed to create 3D cadastral information system prototype based on desktop called SIK3D. Prototype SIK3D comply the terms of land administration which is the input data function as the recording process and information as a function of the information dissemination, the linkages use of space and a space ownership as the space right registration activities. LADM basic class can be adapted to the space raight registration system (3D cadastre) which applicable in Indonesia reference to the Law. No. 20, 2011 about the Flats and Perkaban BPN-RI No. 1, 2010 about Standard Services and Land Regulation

EVALUASI TITIK KUMPUL EVAKUASI (TKE) BANJIR LAHAR HUJAN BERBASIS TESELASI SPASIAL DAN ANALISIS PERGERAKAN EVAKUASI

Mount Merapi eruption in 2010 caused primary and secondary hazards. Primary hazard consist of lava and pyroclastic flow, locally known as wedhus gembel. The secondary hazard, which was also very dangerous, included volcanic ash and lahar flood. Four rivers drained off the volcanic materials of Mount Merapi and overflowed as lahar flood to 13 villages in Kabupaten Magelang. Kali Putih had the most victims and losses among the other rivers. Lahar flood of Kali Putih caused damages in Desa Gulon, Seloboro, Sirahan, and Blongkeng. It was not only harmed people and their houses, but also ruined agricultural land and critical infrastructures. It also forced a mount of people to evacuate in a long period of time. Titik Kumpul Evakuasi (TKE) as evacuation place for lahar flood�s evacuees is one facility that must have been prepared in disaster management according to the Law 24 in 2007 on Disaster Management. REKOMPAK together with the local goverment and the community had planned the TKE in case of lahar flood ever come back in the future as Mount Merapi eruption�s cycle. They had planned the TKE based on assumptions and local agreements. The TKE had not been evaluated whether it could accommodate lahar flood�s evacuees entirely or not. This research was done to find new buildings for TKE, evaluate the TKE, and define the catchment area of each TKE for accommodating the evacuees. Analysis was done to the TKE planned by REKOMPAK and the village goverment threatened by Kali Putih�s lahar flood and the TKE from field survey. The number of inhabitants was distributed to regular hexagonal tessellation calculated in spatial database. The capacity of each TKE for accommodating the evacuees was calculated by formulas based on building areas and building uses. The catchment area of each TKE was analysed in three scenarios using two Catchment Area Analysis methods in Flowmap software. The scenarios were active scenario (day time), passive scenario (night time), and final (combined) scenario. The methods were Second Best Catchment Area Analysis for time evacuation priority and Catchment Area Analysis with Linear Optimization for TKE capacity priority. The result of this research shows that the current proposed TKE are not capable to accommodate all of the Kali Putih lahar flood�s evacuees in active scenario, passive scenario, and final scenario. Second Best Catchment Distance method resulted the catchment area for almost all of the evacuees but it accumulated a huge number of evacuees in some TKEs. Catchment Area Analysis with Linear Optimization method could distributed the evacuees appropriately to fulfill the capacity of each TKE depend on its evacuation capacity, but its catchment area was only accommodating under half of all the evacuees
