Abstract

Semarang City as one of the areas on the north coast has a serious problem related to tidal flooding. The impact of this disaster has implications for changes in land use, a decrease in environmental quality and health, the emergence of slum settlements, a decrease in income and also a decrease in land value. This study aims to map the impact of tidal flooding on changes in land values based on the Land Value Zone Map (ZNT) and map land prices based on spatial data analysis. The study was carried out through spatial analysis by overlaying (join intersection) the 2014, 2016, 2018 and 2019 ZNT maps to determine changes in land value, while mapping land prices, especially in Mangunharjo Village, was based on land use maps, positive accessibility (road network) and negative accessibility (prone flood rob). The results of the study show that land which is permanently affected by tidal flooding and cannot be used anymore makes it a lost / destroyed land, while periodically inundated land has experienced a price decline in the range of Rp 100.000 – 200.000, -/m2. Meanwhile, the results of the study from the ZNT map for 2014 to 2019 show a very significant difference in price between zone 1 and a price increase of ± Rp 3.500.000; zone 2 price increase ± Rp 575.000, -, zone 3 at a price range of Rp 385.000, and zone 4 as the tidal flood prone zone only experienced an increase of Rp 250.000,-. In this context, the variable of tidal flooding vulnerability greatly affects the stagnation of land prices and even decreases in land prices, while the positive accessibility variable is the location of land on national and local roads that has experienced a very high price increase.

Abstract: Geospatial data (on horizontal and vertical positions) play an important role in decision making.Regarding that, the issue of funds, diversity of areas, human resources, and non-updated data become great obstacles. This study aims to examine the technological capabilities of Unmanned Aerial Vehicles (UAVs) or Unmanned Aircraft in acquiring and updating geospatial data, evaluating and inspecting changes in the conversion of agricultural land and the environment, as well as describing orthophoto extraction opportunities in digital services based on multipurpose cadastre. This research used a model combination method (concurrent triangulation). Several alternative requirements were derived to design methods of mapping, processing and controlling the quality of application to the concept of Fit For Purpose Land Administration (FFP-LA), and layering with Geographic Information Systems (GIS). The final product of this system is effective to produce and update land base map, evaluate and inspect changes in the conversion of land functions as well as facilitate digital services. The availability of open source software efficiently extracts and combines terrestrial and photogrammetric mapping products in real time and has the opportunity to realize multipurpose cadastre. The involvement of local human resources is applied to ensure legal certainty in the land registration system as well as to improve and strengthen the management of agrarian resourcesAbstract: Geospatial data (on horizontal and vertical positions) play an important role in decision making.Regarding that, the issue of funds, diversity of areas, human resources, and non-updated data become great obstacles.
