Mapping the distribution of buildings can be done by analyzing remote sensing images taken using various vehicles, one of which is the Unmanned Aerial Vehicle (UAV) which can provide very high-resolution images. However, up to now the classification process is often done by manual digitization which is considered less effective and efficient so that an automatic extraction method is needed. In this study, the Convolutional Neural Networks (CNN) method was used to overcome the challenges of building extraction using high resolution aerial photo image data in Campurejo Village, Gresik Regency using the R-CNN where this is expected to be able to help the classification process automatically by using the Mask R-CNN algorithm. input data (training data). the results of the classification are validated and tested for accuracy to produce a large-scale building distribution map, namely 1: 5000. The accuracy of the building classification results using the Mask R-CNN method was tested using a confusion matrix which resulted in a precision value of 94.78%, recall 82.63%, F1 Score 88.29% and accuracy 79.03% for region 1 and for region 2 resulted precision value 98.10%, recall 78.37%, F1 Score 87.13% and accuracy 77.20%.

The existence of a volcano certainly has a positive impact, such as the area around the mountain becomes fertile and has a negative impact due to frequent disasters. One of the active volcanoes in Indonesia is Mount Sinabung. The existence of magma activity in active volcanoes causes changes in shape due to the movement and shift of the soil on the surface of the volcano which is called deformation. Deformation can be determined by terrestrial methods using theodolite, land Sipat and extra-terrestrial methods with GPS observations and processing of SAR image data using InSAR, D-InSAR, MT-InSAR processing methods which include, PS-InSAR and SBAS. This research was conducted to determine the deformation that occurs in the Sinabung volcano using the PS-InSAR method followed by modeling the position of the magma compression source using the Yokoyama model. The Yokoyama model assumes that the Earth's crust is composed of elastic spaces, and the source of the pressure is a small spherical space with hydrostatic pressure that is unidirectional and its expansion is radial. The SAR data used consists of 7 ascending acquisition images and 8 descending acquisition images on the acquisition date of October 1 to December 31, 2020. By processing the image in ascending and descending ways, the LOS velocity rate can be transformed into horizontal and vertical shift values. The results of PS-InSAR processing show that the LOS velocity rate ranges from 394.1 mm/year to 320.7 mm/year in the ascending direction and in descending direction, the LOS velocity rate ranges from -277.5 mm/year to 31.5.8 mm/year. After decomposing the LOS velocity rate, the displacement value of the PS point in the horizontal and vertical directions at the PS1 point is (0.288; -0.037) meters, the PS2 point is (0.004; 0.010) meters and the PS3 point is (0.041, -0.084) meters. So that the position of the center of magma pressure using the horizontal shift value on Mount Sinabung based on the Yokoyama model is located at coordinates","PeriodicalId":30776,"journal":{"name":"Geoid","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41554931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially in the South Coastal area of Pangandaran Regency which has a history of tsunamis with a tsunami run-up height reaching 15.7 meters in 2006 based on data from BPBD Pangandaran Regency. According to the BMKG, the tsunami that occurred killed 664 people. As a disaster mitigation effort, this research analyzed the level of tsunami hazard and determined the location of Temporary Evacuation Places (TES) in the South Coastal Region of the Pangandaran Regency. The hazard level analysis was carried out based on slope data, roughness coefficient, tsunami run-up height, and coastline. Then from the results of the analysis of the hazard level are used to determine the location of TES using the Network Analyst method. The basis for making the distribution of TES locations is by using Service Area analysis based on pre-existing TES distribution locations from BPBD Pangandaran Regency. From this analysis, the distribution of TES locations and coverage areas will be identified. If the Service Area coverage of the distribution of TES locations from BPBD Pangandaran Regency does not cover the entire tsunami-affected area, then additional TES points will be made.

However, the data on land parcels owned by Sidoarjo National Land Agency is different from the data on taxpayers owned by the village government. In this study, a suitability analysis was carried out between the land parcels owned by the National Land Agency and the taxpayer data owned by the Regional Tax Service Agency of Sidoarjo Regency by overlaying the land parcel maps with village maps. Then by making the land value zone first, it can be seen the potential PAD that can be generated from land parcels that do not yet have a tax identity.
