"Jagakarsa is one of "the water catchment areas" in Jakarta that has green open space. The elements and design of the green open space are very important to be studied, in relation to the occurrence of the wild animal particularly birds in this area. The tittle of this study is "A study on biodiversity of green open space in Jagakarsa water catchment area". The report was divided into two sub tittles: "Vegetation structure and composition at the green open space of water catchment area in Jagakarsa", and "Bird inventory at the green open space of water catchment area in Jagakarsa". The objectives of this study are to examine the structure and composition of the vegetation related to the occurrence of birds in the green open space.The study was conducted from July to December 1999 by compiling both primary and secondary data. The study area was divided into four categories; home garden, green belt along the river, cemetery area (modern and traditional), and urban forests.The highest diversity of vegetation was found in home garden, which was consisted of fruits, and plants used as house fence. Over half of plantin species at home garden are ornamental plant. Beside that, heterogeneity plants at home garden showed higher than the other green open space in Jagakarsa, Also, home garden was managed better than the other green open space in Jagakarsa.Generally, people around the river use green belt along the river as fruit garden. Plant species diversity in those belt are lower than home garden and less managed by people. However, at the green belt along Krukut river was found the regenerated of plants. The vegetation neither ornamental nor valuable cemetery plants with urban cemetery concept was dominated by ornamental plants with high esthetical value, which has maximum height less than one meter. In the traditional cemetery, Ptumeria alba, Codeaeum variegatum, Dracaena fragrans were found dominantly planted with irregularity in patterns.There were 28 species of 18 families of birds found in this study. The highest number of species {15 species) was found at the green belt along Ciliwung River, and surrounding of Situ Babakan (14 species). Water birds were found at Ciliwung River, Kali Krukut, and Situ Babakan. Birds that living in high grasses and shrubs also found at these areas. Most of the birds found in the area are insectivore (42,86%).Vegetation is very important for bird, not only as food resources but also as a resting, sleeping, and nesting place. Fruits and flowers as food resources of insect related to the occurrence of birds were discussed in this paper.iv Habitat degadration and bird hunting are threats for the birds. Therefore, community awareness, selection of plant species, and design of vegetation pattern that fulfil the needs of bird are very important for bird conservation in urban city."

"Konvensi keanekaragaman hayati pada dasarnya berisi ketentuan yang meminta negara-negara untuk melestarikan keanekaragaman hayati memanfaatkan dan mengembangkan komponen-komponennya secara berkelanjutan dan membagi keuntungan dari hasil pemanfaatan sumber daya gen secara adil dan merata. Indonesia yang memiliki keanekaragaman hayati yang sangat tinggi tenyata belum memanfaatkan secara maksimal justru negara lain yang memanfaatkannya.Tulisan ini menyoroti hal tersebut dalam perspektif hubungan internasional."

"ndonesia memiliki keanekaragaman hayati yang sangat tinggi di dunia, termasuk keanekaragaman binatang/satwa liar atau fauna. Misalnya, Indonesia menempati peringkat pertama di dunia dengan memiliki keanekaragaman jenis mamalia (515 jenis); dengan memiliki keanekarahaman jenis burung (1.539 jenis), Indonesia menempati peringkat ke-4 di dunia—di bawah Kolumbia, Peru dan Brazil; serta memiliki keanekaan jenis reptilia (600 jenis) sehingga Indonesia berada di peringkat ke-3, setelah Meksiko dan Australia. Namun dalam beberapa dasawarsa terakhir ini, keanekaragaman binatang di Indonesia yang berperan penting bagi fungsi ekologi, sosial ekonomi dan budaya manusia malah banyak diperlakukan tidak wajar oleh manusia, seperti diburu, dibunuh, dan dirusak atau dimusnahkan habitatnya. Akibatnya, beberapa jenis binatang terancam punah.Buku ini membahas tentang berbagai jenis binatang yang berperan penting bagi ekologi di alam atau di ekosistem, seperti penyebar biji-bijian, penyerbuk tumbuhan, pengendali hama tumbuhan/tanaman, indikator kualitas lingkungan perairan, indikator perubahan musim, indikator timbul bencana alam, dan penghasil sarang walet yang sangat menguntungkan bagi kepentingan bisnis. Oleh karena itu, buku ini sangat penting untuk dibaca oleh berbagai kalangan untuk mengenal jenis-jenis binatang di Indonesia, yang menguntungkan bagi alam sehingga"

"Dinamika keanekaragaman hayati seringkali dikaitkan dengan perubahan lingkungan, termasuk kedalaman perairan, produktivitas, sifat sedimen, ketersediaan oksigen, morfologi, serta gangguan fisik lainnya. WPPNRI 573 adalah salah satu dari 11 wilayah pengelolaan perikanan di Indonesia yang memiliki karakteristik geografis dan oseanografis yang unik. Isu yang berkembang pada WPPNRI 573 antara lain eksploitasi berlebih, degradasi habitat, pencemaran dan penangkapan tidak ramah lingkungan, serta masuknya spesies invansif yang terjadi karena kurangnya wawasan dan perhatian pemerintah, serta kurangnya sumberdaya manusia dalam hal pengelolaan. Penelitian ini bertujuan untuk menyajikan informasi terkait resiko ancaman kepunahan keanekaragaman hayati serta variasi morfologi yang mempengaruhinya. Metode yang digunakan dalam penelitian ini adalah analisis spasial dan spasio-temporal dengan Red List Index sebagai model penilaian distribusi wilayah resiko keanekaragaman hayati. Sampel data keanekaragaman hayati dikumpulkan dari GBIF.org dalam rentang tahun 1989-2023. Hasil penelitian mengungkapkan bahwa resiko terhadap ancaman kepunahan kehati di wilayah WPPNRI 573 cenderung rendah. Spesies lebih dominan berdistribusi secara mengelompok pada zona epipelagik dan semakin terdistribusi secara menyebar pada zona laut yang semakin dalam. Morfologi berpengaruh signifikan dalam level moderat terhadap distribusi keanekaragaman pada kategori nilai resiko ancaman yang sama. Kedalaman memiliki pengaruh yang paling besar, diikuti dengan lereng. Sedangkan orientasi, kelengkungan, dan kekasaran tidak memiliki pengaruh yang signifikan.

The biodiversity dynamics are often associated with environmental changes, including water depth, productivity, sediment characteristics, oxygen availability, geomorphology, and other physical disturbances. WPPNRI 573 is one of 11 fisheries management areas in Indonesia that has unique geographical and oceanographic characteristics. Issues that occurred in WPPNRI 573 include overexploitation, habitat degradation, pollution, and non-eco-friendly fishing, as well as the entry of invasive species that occur due to lack of government insight and attention, and also lack of human resources in terms of management. This study aims to present information about the risk of biodiversity extinction threats and geomorphological variations that affect it. The method used is spatial and spatial-temporal analysis with Red List Index as a model for assessing the distribution of biodiversity risk areas. Samples of biodiversity data were collected from GBIF.org between 1989 and 2023. The results revealed that the risk of biodiversity extinction in the WPPNRI 573 area tends to be low of biodiversity extinction risk status. Species are predominantly distributed in clusters in the epipelagic zone, and also dispersed in deeper marine zones. Geomorphology has a significant moderate effect on the distribution of diversity in the same threat risk value category. Depth has the most influence, followed by a slope. While aspect, curvature, and ruggedness do not have a significant effect."
