Judul: Keanekaragaman dan Aktivitas Capung (Ordo : Odonata)  di Kebun Raya Bogor
Abstrak: Indonesia adalah negara yang memiliki keanekaragaman hayati termasuk di dalamnya keanekaragaman spesies serangga. Secara geografis, keanekaragaman hayati di negara kepulauan Indonesia sangat beragam.Serangga jenis capung termasuk salah satu kekayaan keanekaragaman hayati di Indonesia.Kelestarian capung perlu dipelihara dengan menjaga keberadaan tempat hidupnya yang sebagian besar berupa perairan. Kebun Raya Bogor memiliki ragam koleksi flora dan merupakan tempat bernaung bagi berbagai jenis fauna seperti serangga, laba-laba, siput, burung dan sebagainya. Penelitian yang sudah banyak dilakukan hanya seputar jumlah spesies tanaman, burung, dan lain-lain. Penelitian tentang serangga, khususnya capung, masih tergolong sedikit. Aspek keragaman dan aktivitas capung di sekitar area Kebun Raya Bogor belum banyak diketahui. Oleh karena itu, perlu adanya penelitian yang berkala untuk mengetahui keragaman dan aktivitas capung. Metode yang dilakukan di dalam penelitian ini dengan menangkap capung dengan jaring serangga. Selain itu, selama di tempat pengamatan juga diamati aktivitas capung tersebut. Tahap selanjutnya adalah mengidentifikasi jenis spesies capung menggunakan literatur Australian’s Dragonflies dan A Pocket Guide to Drgaonflies of Peninsular Malaysia and Singapore. Jenis capung yang ditemukan sebanyak sepuluh spesies capung yaitu Orthetrum sabina, Pantala flavescens, Brachythemis contaminata, Neurothemis sp., Crocothemis servilia, Zyxomma obtusum, Hydrobasileus croceus, Ictinogomphus decoratus, Pseudagrion microcephalum, dan Pseudagrion rubriceps. Kesepuluh jenis capung ini tersebar di beberapa lokasi di Kebun Raya Bogor yaitu, Taman Lebak Sudjana Kassan, Kafe Dedaunan, Koleksi Tanaman Air, dan Istana Bogor. Aktivitas utama capung adalah terbang dan hinggap di atas permukaan tanaman air atau batu. Aktivitas capung dapat dipengaruhi oleh keberadaan air sungai, cuaca saat pengamatan, dan keberadaan tanaman air sebagai tempat hinggap. Faktor yang mempengaruhi aktivitas capung adalah keberadaan air sungai, cuaca, dan keberadaan tanaman air sebagai tempat hinggap.

Judul: Pengaruh Karakteristik Habitat Ruang Terbuka Hijau terhadap Keanekaragaman Kupu-Kupu (Studi Kasus di Kebun Raya Bogor)
Abstrak: Bogor Botanical Garden (BBG) which functions as an ex-situ conservation places is one of the green open space (GOS) in Bogor and also home to many kinds of animals including butterflies. Butterfly serve as bioindicator of the ecological function of green open space. The purpose of this research was to determine diversity, eveness, and the similarity habitat use by butterflies on five habitat types in Bogor Botanical Garden in order to clarify the relationship between of biotic and abiotic factors in green open spaces and butterfly assemblages. This research was conducted from November to December 2011. Data collected were butterfly species and population, habitat characteristic, and vegetation analysis. Butterfly diversity was investigated by using line transect count method in five types of habitats which were surveyed in the morning (08:00-12:00) with three repetitions in the daytime under fine weather conditions. The following five transects were selected in this study: (1) Fruit plants habitat, (2) Mediterranean plants habitat, (3) Woody plants habitat, (4) Aquatic plants habitat, and (5) Garuda Garden. The diversity was calculated by using species diversity index (H’), eveness index (E) and similarity index (Sj). The relationships between biotic and abiotic factors to butterfly population were also determined. Based on survey in five sites, a total of 60 species belonging of five families : Papilionidae (7 species), Nymphalidae (33 species) Pieridae (13 species), Lycaenidae (6 species), and Hesperiidae (1 species) were captured and identified. Butterfly’s habitat preferences are: 1) The optimum temperature for a butterfly is between 28 0C-34 0C, 2) Buterflies originally found in relatively open habitats (large value of the GSF and small value of LAI), 3) Butterfly need a variety of larval host plant, nectar resources, and shelter, and 4) Have a water source, especially stagnant water source. This study shows that the provision of adequate nectar resources and larval host plant are likely to be essential to the successful conservation of butterfly species.

Abstrak: At an emergency unit of a hospital are generally posted several physicians for 24 hours for each and every day. The management unit of an emergency room usually has to deal with schedulling problem of physicians with time constraint of availability. This scheduling problem can be modeled as an integer linear programming (ILP) problem. ILP is an optimization problem with linear objective function, linear constraints, and integer variables. Scheduling problem is formulated in an optimization model, where the objective function is to minimize the operational cost of emergency room with the following constraints: (i) the time availability of physicians, (ii) the balanced work load for every physicians, (iii) holiday and dayoff determination of each physician. This paper discusses the schedulling of an emergency room’s physicians problem in the form of ILP, with a case study at Emergency Unit of Cipto Mangunkusumo Hospital (RSCM), Jakarta. The model is solved using Lingo 8.0 software. The solution obtained using ILP scheduling method is found to be more balanced than the corresponding solution using conventional method.
