Judul: Kekayaan Jenis Burung pada Habitat Perairan sebagai Potensi Wisata Birdwatching di Tambling Wildlife Nature Conservation, Taman Nasional Bukit Barisan Selatan Provinsi Lampung.
Abstrak: Tambling Wildlife Nature Conservation (TWNC) is a conservation area located in Bukit Barisan Selatan National Park (TNBBS). The management of this area is conducted by PT. Adhiniaga Kreasinusa through the Minister of Forestry Decree No.415/Kpts-II/1992 using IPPA (The Consension of Nature Tourism Bussiness) . Tourism activity that has been already run in this area is night safari. To maximize the visitation to this area, other tourism activities should be provided to give more experiences to visitors and contribute positive impact for conservation. One of alternative tourism is birdwatching. The objectives of this study are to record bird species, count the abundance of bird, describe bird spatial and temporal distribution, and give recommendations for birdwatching tourism. Habitats in TWNC consisted of coastal forest, mangrove forest, lowland forest, and aquatic habitats (lakes, beaches, swamps, estuaries and coral reefs). The study was conducted in the aquatic habitats of TWNC (lakes, beaches, estuaries). Preliminary survey was conducted in October 2008 and the research was conducted in August-September 2009. Data was collected by using concentration count methods, survey methods and the “look and see” methods. Data analysis was done by counting bird species richness, abundance, and distribution at each study site. Bird species distribution was analyzed based on the place (spatial distribution) and time of daily activity (temporal distribution). There were 83 bird species found in TWNC. The highest abundance was sea Imperial-pigeon (Ducula bicolor). The species that were commonly found in every locations included Copsychus saularis, Egretta sacra, Charadrius dubius, Tringa hypoleucos, and Todirhamphus chloris. Species that was found in only certain locations were Burhinus giganteus, Egretta garzetta, and Eudynamys scolopacea. Most bird activities occurred between 06.00-10.00 a.m. and 03.00 – 06.00 p.m. The potential species for Birdwatching are Burhinus giganteus, Leptoptilos javanicus, Phaenicophaeus spp., Haliaeetus leucogaster, Ichthyophaga ichthyaetus, Anthracoceros albitrosis, Ardea sumatrana, Pelargopsis capensis, and Egretta sacra. The recommended locations for Birdwatching are Saung Bajau, Sei Leman, Way Tinggal, and Menjukut. The birdwatching activity will be better if done during 06.00-10.00 am (morning) and between 03.00-06.00 pm. The results of this study is expected to be a baseline data for managers to prepare packages of special interest toursim, that is birdwatching, in TWNC area, and conduct birds monitoring in aquatic habitats. In addition, the manager is expected to provide infrastructure and facilities for birdwatching activities such as birds observation equipment, interpretation boards, leaflets and guide person.

Judul: Perencanaan Interpretasi Wisata Birdwatching di Resort Balik Bukit Taman Nasional Bukit Barisan Selatan.
Abstrak: Keanekaragaman dan kekayaan burung di Taman Nasional Bukit Barisan Selatan sangat tinggi, salah satunya di Resort Balik Bukit. Hal tersebut merupakan peluang bagi pengembangan wisata birdwatching. Penelitian ini bertujuan mengidentifikasi jenis dan sebaran burung, menganalisis harapan dan keinginan pengunjung dan publik dan menyusun perencanaan interpretasi. Penelitian dilaksanakan pada bulan April-Mei 2018. Data dikumpulkan melalui telaah pustaka, pengamatan lapangan dan wawancara. Perencanaan interpretasi mengacu pada enam elemen Veverka (what, why, who, how/where/when, implementation and operations, so what). Hasil inventarisasi dijumpai 154 individu burung yang terdiri dari 53 jenis dan 28 famili. Burung yang berpotensi untuk dijadikan objek interpretasi terdiri dari sebelas jenis yaitu burung langka, burung endemik dan burung raptor. Tema besar program adalah “Pesona Burung-Burung Resort Balik Bukit sebagai Kekayaan Sejarah Alam Bukit Barisan Selatan”. Tujuan interpretasi wisata birdwatching yaitu 1) meningkatkan pengetahuan dan kesadaran pengunjung terhadap keanekaragaman jenis burung; 2) sarana promosi kawasan wisata alam RBB sebagai tujuan wisata, serta sarana pendidikan dan penelitian. Jalur yang digunakan yaitu jalur Sepapa Kiri (pengamatan burung langka) jalur ini disarankan untuk pengamat pemula (novice), jalur Sepapa Kanan (pengamatan burung endemik dan burung langka) jalur ini disarankan untuk pengamat tingkat lanjut (advanced) dan jalur Penayuhan (pengamatan burung endemik dan raptor) jalur ini disarankan untuk pengamat menengah (intermediate).

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.
