"Perairan Pemuteran merupakan salah satu tujuan lokasi wisata di Bali yang cukup ramai dikunjungi karena keindahan terumbu karang bawah lautnya. Terumbu karang perlu dilestarikan karena selain bermanfaat di bidang ekonomi, terumbu karang dapat bertindak sebagai penghalang alami terhadap bencana alam seperti badai, topan, bahkan tsunami. Kajian terkait identifikasi spasial morfologi dasar laut dan sebaran bentuk di ekosistem terumbu karang dapat membantu memahami karakteristik dan keunikan dari ekosistem. Sehingga penelitian ini bertujuan untuk melakukan pemetaan morfologi dasar laut untuk melihat hubungannya dengan sebaran habitat bentik di Perairan dangkal Pemuteran. Metode yang digunakan dalam membangun zona morfologi dasar laut dengan melakukan deliniasi peta batimetri dengan peta kemiringan lereng wilayah penelitian. Sedangkan sebaran habitat bentik dihasilkan dari segmentasi menggunakan metode Object Based Image Analysis (OBIA). Secara garis besar, terdapat 2 tipe terumbu karang diwilayah penelitian yaitu tipe fringing reef dan atols. Selain itu, dalam penelitian ini ditemukan 3 zona geomorfologi terumbu karang yaitu reef flat, reef crest dan reef slope. Hasil deliniasi peta batimetri dan kemiringan lereng menghasilkan 7 unit morfologi dasar laut yaitu shoreline, shallow bench (bench dangkal), shallow cliff (jurang dangkal), shelf break, intermediate bench, dan deep cliff. Berdasarkan hasil pemetaan tersebut, unit morfologi shallow bench menjadi unit paling dominan yang terdapat di wilayah penelitian. Secara umum, terdapat 6 jenis habitat bentik yaitu rubble, lamun, karang mati, karang hidup, batu, dan pasir. Pada akhirnya, penelitian ini menemukan bahwa sebaran habitat bentik sangat berkaitan dengan morfologi dasar laut.

Pemuteran waters is one of the tourist destinations in Bali which is quite crowded because of the beauty of the underwater coral reefs. Coral reefs need to be preserved because apart from being economically beneficial, coral reefs can act as a natural barrier against natural disasters such as hurricanes, typhoons, and even tsunamis. Studies related to the spatial identification of seabed morphology and distribution of benthics in coral reef ecosystems can help understand the characteristics and uniqueness of the ecosystem. This study aims to map the seabed morphology to see its relationship with the distribution of benthic habitats in Pemuteran shallow waters. The method used in constructing the morphological zone of the seabed is by delineating the bathymetric map with the slope map of the research area. While the distribution of benthic habitats is generated from image segmentation using the Object-Based Image Analysis (OBIA) method. There are two types of coral reefs in the study area: fringing reef and atolls. In addition, this study found three morphological zones of coral reefs, namely reef flat, reef crest, and reef slope. The delineation results of the bathymetry and slope maps produced seven units of seabed morphology, namely shoreline, shallow bench, shallow cliff, shelf break, intermediate bench, and deep cliff. The shallow bench morphology unit is the most dominant in the study area based on the mapping results. In general, there are six types of benthic habitat, namely rubble, seagrass, dead coral, live coral, rock, and sand. In the end, this study found that the distribution of benthic habitats is closely related to the morphology of the seafloor."

"Latar belakang penelitian ini adalah pemekaran kota Bogor yang berimplikasi pada alih fungsi lahan akibat pertumbuhan dan kebutuhan sarana dan prasarana sehingga menggantikan lahan yang tidak memberikan dampak ekonomi secara langsung yaitu Ruang Terbuka Hijau (RTH). Keberadaan RTH mengalami perubahan nyata total luas lahan dari tahun ke tahun khususnya pada tahun 2009 sebesar 5.459,5 ha, tahun 2013 sebesar 5.321,1 ha, dan tahun 2022 sebesar 4.772,5 ha. Penelitian ini bertujuan untuk melakukan deteksi penutup lahan RTH dengan menganalisis perubahan spasial penutup lahan RTH berdasarkan informasi yang dapat diperoleh dari interpretasi citra dengan klasifikasi object based dan menjelaskan parameter yang digunakan, uji akurasi yang dilakukan, dan perubahan spasial RTH. Proses ini mempertimbangkan keakuratan klasifikasi dengan menggunakan data referensi citra Maxar Google Earth Pro yang disesuaikan dengan citra-citra yang digunakan dalam penelitian, menggunakan perhitungan Confusion Matrix untuk uji akurasi sehingga menghasilkan nilai kappa keakuratan penutup lahan RTH di kota Bogor. Hasil dari penelitian ini adalah kelas Lahan Terbangun menjadi faktor perubahan sehingga lahan RTH mengalami penurunan nilai luas lahan. Kelas Lahan Terbangun kian meningkat akibat terjadinya urbanisasi yang memengaruhi peningkatan angka jumlah penduduk, kemudahan aksesibilitas dalam kota dan antarkota, sehingga memunculkan laju ekonomi yang baik. Oleh karena itu, terjadilah alih fungsi lahan di kota Bogor, sehingga kebutuhan akan lahan meningkat dan berpengaruh pada terjadinya perubahan penutup lahan untuk menunjang kehidupan masyarakat. Hasil uji klasifikasi object based setiap tahunnya memiliki nilai yang baik yaitu 0.73 untuk tahun 2009 dan 2013 serta 0.74 untuk tahun 2022 sehingga layak. Hasil akhir penelitian adalah melakukan strategi penyediaan RTH yaitu memulihkan lahan yang telah beralihfungsi.

The background of this research is the expansion of the city of Bogor which has implications for land conversion due to growth and the need for facilities and infrastructure so that it replaces land that does not have a direct economic impact, namely Green Open Space (RTH). The existence of green open space has changed in total land area from year to year, especially in 2009 it was 5,459.5 ha, in 2013 it was 5,321.1 ha, and in 2022 it was 4,772.5 ha. This study aims to detect green open space land cover by analyzing spatial changes in green open space land cover based on information that can be obtained from image interpretation with object based classification and explaining the parameters used, accuracy tests performed, and spatial changes to green open space. This process takes into account the accuracy of the classification by using Maxar Google Earth Pro image reference data which is adjusted to the images used in the study, using the Confusion Matrix calculations for the accuracy test to produce an accurate kappa value for green open space in the city of Bogor. The results of this study are that the built-up land class is a factor of change so that green open space experiences a decrease in the value of land area. The class of built-up land is increasing due to urbanization which affects the increase in population numbers, ease of accessibility within cities and between cities, giving rise to good economic growth. Therefore, there has been a change in land use in the city of Bogor, so that the need for land has increased and this has affected land cover changes to support people's lives. The results of the object based classification test each year have a good value of 0.73 for 2009 and 2013 and 0.74 for 2022 so it is feasible. The final result of the research is to carry out a strategy of providing green open space, namely restoring land that has been converted.

"The twin sets of figures in the manual are presented as examples that demonstrate how the interfacing of stereo airphotos and satellite images in visual qualitative photogeomorphology studies can yield more geospatial information than can be derived from either source independently. The airphoto coverage in each satellite image is indicated by a frame. The photos and images are ordered into eleven sections according to the author’s taxonomic classification of genetic groups as used in his Atlas and Glossary of Geohazard-associated Geounits. The figure sets of each section are preceded by characterisations of their genetic classification context. Some airphotos are taken from those used in the Atlas, the satellite images have been down loaded from USGS Global Visualitation Viewer.

"Thanks to recent advances in sensors, communication and satellite technology, data storage, processing and networking capabilities, satellite image acquisition and mining are now on the rise. In turn, satellite images play a vital role in providing essential geographical information. Highly accurate automatic classification and decision support systems can facilitate the efforts of data analysts, reduce human error, and allow the rapid and rigorous analysis of land use and land cover information. Integrating Machine Learning (ML) technology with the human visual psychometric can help meet geologists demands for more efficient and higher-quality classification in real time. "
