Judul: onservation Analysis of Mangrove Ecosystem in Bungus Teluk Kabung Sub District, Padang-West Sumatera Province.
Abstrak: Mangroves are one of the most productive features of coastal ecosystem across tropical and subtropical regions of the world such as in Bungus Teluk Kabung Sub District that is divided in two villages (Teluk Kabung Tengah VillagefTKT and Teluk Kabung Selatan VillagefTKS) as the area study that degraded and there is no the strategic plan. So, this research was done to identify the mangrove ecosystem potential, problem in existing condition, determine the mangrove ecosystem zonation and to develop strategic plan of mangrove ecosystem for conservation development Field research was done on March, May to June 2006 in Bou Bay- Bungus Teluk Kabung Tengah Village and Olo Bay-Teluk Kabung Selatan Village. Mangrove ecosystem observation was done by line transect method and rapid method that was measured the diameter breast height, water and substrate quality, fisheries biodiversity identification and stakeholders perception. Mangrove vegetation in Buo Bay-TKT mangrove vegetation was dominated by Rhizophora apiculata seedlings that had the highest influence of the community and ecosystem mangrove. Ecosystem Mangrove in Olo Bay-TKS mangrove ecosystem was dominated by Ceriops tagal seedlings but Sonneratia alba trees had highest influence of the community and ecosystem mangrove. This area is highly suitable for conservation area and should be established regulation as Landscape/Seascape Conservation category through using the local community institution as the strength subject to utilize the local government and non local government organization as the opportunities subject in strategic plan of mangrove ecosystem conservation to manage the protection of specific cultural and maintenance of traditional attribute, tourism and recreation activity in mangrove ecosystem area, scientific research and education, preservation of species and genetic diversity, sustainable use of mangrove forest, maintenance of environment services and improve institutional capacities in managing mangroves conservation activity.

Judul: Management Strategy of Sustainable Mangrove Ecosystem of Tarumajaya District, Bekasi Regency
Abstrak: Existence of mangroves in Tarumajaya District, Bekasi Regency is threatened by human activities such as land conversion to fish ponds, sand mining, and logging for firewood that has become less massive in recent years. This is quite large influenced by the socio-economic conditions of the community. If still allowed, the degradation rate of the mangrove ecosystem will threaten its existence and all the biota that live in it. The mangrove area in Tarumajaya District, Bekasi Regency still has a relatively unstable mangrove forest ecosystem and has experienced degradation due to unplanned and uncontrolled land use. This condition requires attention from related parties so that the sustainability and stability of the ecosystem can be maintained. The damage to an ecosystem can affect other ecosystems, therefore, mangrove ecosystems play an important role, especially in coastal and marine areas. Lack of information about the characteristics of mangrove ecosystems and the socio-economic characteristics of coastal communities is one of the obstacles for local governments to formulate appropriate sustainable mangrove management policies. This study aims to: (1) analyze the environmental (biophysical) condition of mangrove ecosystem in Tarumajaya District, (2) analyze the socio-economic conditions of community of Tarumajaya District, Bekasi Regency, (3) measure the sustainability status of mangrove ecosystem management in Tarumajaya District, Bekasi Regency, (4) formulate the alternative strategies and priority scales for mangrove ecosystem management in Tarumajaya District, Bekasi District. Research was conducted from December 2020 - to February 2021, located in Tarumajaya District, Bekasi Regency. The method used in this research is a survey method with purposive sampling. Primary data collection was obtained through direct field observation and structured interviews with questionnaires. Secondary data collection was obtained through surveys on related agencies and literature studies. Data analysis used in this research includes quantitative and descriptive analysis. Quantitative analysis provides vegetation analysis, land cover, multidimensional scaling (MDS) using RAPFISH, the direct value of mangrove ecosystems, socio-economic and cultural conditions of the community, community perceptions using Likert scale and mangrove management strategies through SWOT and QSPM. Results showed that the tides occur on average 2 times a day, salinity ranges from 23-25 ppt, water temperature ranges from 28-29.9⁰C, water pH ranges from 7.3 to 7.5, and the substrate is sandy mud and dark brown to dark black. Composition and structure of mangrove species found in the coastal area of Tarumajaya District consist of 7 species from 3 families, namely Rhizophora mucronata, Rhizophora apiculata, Avicennia alba, Avicennia marina, Avicennia officinalis, Sonneratia alba, Sonneratia caseolaris with a high category of evenness index (0.74-0.99), low category species diversity index (1.00-1.81). Land cover change at the 3 observation stations increased from 60.33 ha in 2016 to 83.99 ha in 2020, Tarumajaya District has a dense category of mangrove about 82.02 Ha, moderate 45.49 Ha, and rarely 294.67 Ha. The diversity of fish are good, amphibians are bad, reptiles are moderate, mammals are rather bad, and birds are very good. Quantification of the direct benefit value of the mangrove ecosystem in the coastal area of Tarumajaya District shows a total benefit value of IDR 2.077.584.000/year, obtained from fish catch IDR 643.840.000; Crab

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
