Judul: Inventarisasi cacing saluran pencernaan elang Jawa (Spizaetus bartelsi Stressman, 1924) dan Elang Brontok (Spizaetus cirrhatus Gmelin, 1788) di habitat eks-situ
Abstrak: Wildlife Rescue Center and Raptor Sanctuary are an ex-situ habitat for wildlife rehabilitation of confiscated and voluntary handover of illegal trading and poaching. This is the efforts to conserv wildlife from extinction. At present there is a few of javan hawk eagle and changeable hawk eagle on ex-situ habitat. Its existence can not avoid from the attack of various diseases, such as parasitic worm infections. The research aimswas to study the types and degree infection of gastrointestinal parasitic worms on javan hawk eagle and changeable eagle. This research was also a preliminary study in studying the behavioral factors and eagle health management at rehabilitation which may affect the transmission of parasitic worms. This research was conducted at Raptor Sanctuary, Cikananga Wildlife Rescue Center, and Gadog Wildlife Rescue Center on December 2009 until July 2010 by observed 16 eagles, which consisted of 4 javan hawk eagle and 12 changeable hawk eagle. Stage of research included field observation consisting of behavioral observation and fecal sampling. Behavioral observation was performed by Ad Libitum Sampling method and recorded by Time Sampling method. The stool sample done at each individual based on the time-making and observation of physical condition of fecal. The next stage was to analyze fecal samples on laboratory by Koprologi method which included qualitative and quantitative examination. Qualitative examination was done by flotation method and sedimentation followed by filtration storey. Quantitative examination was done by McMaster method. The type of parasitic worms found in this study are trematoda group consisting of Strigea sp dan Neodiplostomum sp, and the nematode group consisting of Heterakis sp, Ascaridia sp, and Capillaria sp. The type of parasitic worms found in javan hawk eagle are Ascaridia sp, Strigea sp, and Capillaria sp, whereas in changeable hawk eagle are Strigea sp, Neodiplostomum sp, Heterakis sp, Ascaridia sp dan Capillaria sp. There are two types of eggs worm, i.e. Ascaridia sp with 147,5 TTGT value which found in changeable hawk eagle on Cikananga Wildlife Rescue Center and Capillaria sp with 1868 TTGT value in javan hawk eagle on Gadog Wildlife Rescue Center. Transmission of worm infestation in those eagles allegedly influenced by several behavioral factor and wildlife management in ex-situ habitat.

Judul: Perilaku Harian dan Pengelolaan Burung Elang Brontok (Nisaetus cirrhatus) di Pusat Konservasi Elang Kamojang Jawa Barat
Abstrak: Elang brontok (Nisaetus cirrhatus) merupakan burung pemangsa (predator) yang saat ini mengalami penurunan jumlah spesies di alam. Salah satu upaya untuk menjaga kelestarian populasinya adalah dengan cara konservasi in-situ dan rehabilitasi. Tujuan penelitian ini adalah untuk mengetahui perilaku harian, pengelolaan burung di Pusat Konservasi Elang Kamojang, serta menganalisis kriteria perilaku untuk kesiapan sebelum dilepasliarkan. Penelitian dilakukan pada bulan Februari sampai bulan Maret 2021 di Pusat Konservasi Elang Kamojang Jawa Barat. Pengamatan perilaku harian menggunakan metode Focal Animal Sampling, dan pengelolaan menggunakan metode wawancara, studi literatur, dan observasi. Perilaku harian Elang brontok (Nisaetus cirrhatus) di Pusat Konservasi Elang Kamojang yaitu perilaku diam (58,61%) yang meliputi aktivitas berdiri santai, melihat ke kiri dan ke kanan, menggeliat; perilaku bergerak (18,95%) meliputi menelisik, bersuara, membersihkan badan sambil menggetarkan tubuh, menggerakan ekor, berpindah, meluncur, dan terbang; perilaku makan (ingestif) (22,44%) meliputi aktivitas makan dan defekasi. Kegiatan pengelolaan meliputi kegiatan pengelolaan kandang, pengelolaan pakan, dan pengelolaan kesehatan., Changeable Hawk Eagle (Nisaetus cirrhatus) is a bird of prey (predator) that is currently experiencing a decline in the number of species in nature. One of the efforts to preserve the population is employing in-situ conservation and rehabilitation. The purpose of this study was to determine the daily behavior, management of birds at the Kamojang Eagle Conservation Center, and to analyze behavioral criteria for readiness before being released into the wild. The research was conducted from February to March 2021 at the Kamojang Eagle Conservation Center, West Java. Observation of daily behavior using Focal Animal Sampling method, and management using interviews, literature study, and observation. The daily behavior of Changeable Hawk Eagle (Nisaetus cirrhatus) at the Kamojang Eagle Conservation Center is silent behavior (58.61%) which includes activities of standing relaxed, looking left and right, squirming; moving behavior (18.95%) includes searching, making sounds, cleaning the body while shaking the body, moving the tail, moving, gliding, and flying; eating behavior (ingestive) (22.44%) includes eating and defecation activities. Management activities include cage management, feed management, and health management.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
