Urban Slum settlements continue to occur as one of the impacts of urbanization so that it becomes one of the main problems and focuses on city planners. Planning and structuring slum settlements require an up-to-date base map as an accurate source that describes the slum’s local situation of the slum. Unmanned Aerial Vehicle (UAV) can provide it. This study used UAV to extract physical characteristics of urban slum settlements located in the Cibogor area within the Bogor Tengah sub-district near Cibalok River banks Bogor-Jakarta railways. The point dense cloud process performed to extract elevation consists of Digital Terrain Model (DTM) and Digital Surface Model (DSM). Both elevations were used to generate normalized DSM (nDSM) and integrated with Multi-Resolution Segmentation (MRS) to provide the first classification stage. RGB indexes are computed to provide the second classification stage from the images. Physical characteristics were successfully identified to classify slum settlements and distinguish from formal settlements. The resulted map from OBIA has shown valuable spatial information of slum area to support Development Goals (SDGs), precisely at point 11 regarding Sustainable Cities and Communities, to improve the quality of slum settlements.

Garis Pantai di wilayah pesisir Kecamatan Kaliori, Kabupaten Rembang setiap tahun selalu mengalami perubahan. Perubahan ini diakibatkan dari proses akresi dan abrasi. Tujuan dari penelitian ini adalah untuk mengetahui perubahan garis pantai yang terjadi pada pesisir utara Kecamatan Kaliori, Kabupaten Rembang, Provinsi Jawa Tengah selama satu dekade terakhir. Penelitian ini menggunakan data sekunder citra multi temporal resolusi tinggi Google Earth tahun 2009, 2012, 2013, 2015, 2017, dan 2019. Sistem informasi Geografis (SIG) diintegrasikan dengan data penginderaan jauh digunakan untuk mendeteksi perubahan garis pantai dan luas abrasi dan akresi yang terjadi di daerah penelitian. Hasil dari penelitian ini menunjukkan perubahan garis pantai disebabkan oleh akresi dan abrasi. Dari tahun 2009 hingga 2019, jumlah titik lokasi yang mengalami akresi adalah 63 titik, sedangkan titik yang ter-abrasi terdeteksi ada 44. Luas daerah pesisir yang mengalami akresi sebesar 70,2 Ha dan abrasi 5,08 Ha. Perubahan garis pantai di bagian barat didominasi oleh proses akresi sedangkan pada bagian timur pesisir Kecamatan Kaliori didominasi oleh proses abrasi.

In 2019, Depok Municipality in Indonesia has participated for the second times in PROKLIM (Program Kampung Iklim-bahasa) which is focussed in RW 10 Baktijaya Village. In previous year, community activities in biopori holes, family herbal planting (TOGA) and rainwater infiltration well (RIW) was difficult to be updated. Therefore, in this study unmanned aerial vehicle (UAV) is applied to acquire location of PROKLIM in Baktijaya village with very high resolution image. Herein, DJI Phantom 4 Pro was flown at 100 m height to capture images of participated houses. The image from UAV then processed with Agisoft Photoscan to generate orthophoto image. With the guiandce from local community leader, biopori hole, TOGA and RIW locations were tagged using Avenza Maps and input into ArcGIS. Layers from UAV images and field survey then integrated to produce maps of biopori hole, TOGA and RIW activities. The map of PROKLIM activities was successfully generated from UAV image and Avenza Maps application. Resulted maps are very useful for updating submission to PROKLIM registration website in Indonesia’s Ministry of Environment and Forestry.
