Judul: Karakteristik morfologis dan teknik pemeliharaan tokek dan cicak di penangkaran PT Mega Citrindo
Abstrak: Keberadaan tokek dan cicak belum menjadi salah satu jenis yang banyak diincar orang untuk diperdagangkan sebelum tahun 2010. Salah satu perusahaan yang telah melakukan perdagangan tokek dan cicak adalah PT Mega Citrindo, yang telah bergerak di usaha perdagangan famili Gekkonidae sejak tahun 2000. Status perlindungan dari tokek dan cicak tersebut belum masuk dalam daftar satwa dilindungi dalam APPENDIX CITES, namun keadaan tersebut dikhawatirkan akan mengalami kepunahan di masa yang akan datang. Hingga tahun 2010 kegiatan untuk budidaya terhadap tokek dan cicak masih belum banyak dilakukan. Faktor yang melatarbelakanginya adalah perilaku alaminya yang rentan stres terhadap sentuhan tangan manusia. Tujuan penelitian ini adalah (1) mengetahui karakteristik morfologis tokek biasa, tokek bergaris dan cicak terbang; (2) mengetahui teknik pemeliharaan tokek biasa, tokek bergaris dan cicak terbang di penangkaran di PT Mega Citrindo. Secara umum seluruh data yang di ambil menggunakan beberapa metode yaitu pengukuran, pengamatan, dan studi literatur. Data yang dikumpulkan meliputi karakteristik morfologis dan teknik pemeliharaan. Hasil pengamatan terhadap karakteristik morfologi menunjukan bahwa dalam kriteria perdagangan hanya ukuran berat badan yang mempengaruhi penjualan kepada konsumen. Ukuran panjang total dan SVL digunakan untuk membedakan jantan dan betina dalam suatu penelitian ilmiah. Hasil analisis terhadap teknik pemeliharaan di PT Mega Citrindo menunjukan bahwa sistem kandang dilakukan secara berkelompok. Seluruh jenis tokek dan cicak yang menjadi objek penelitian berasal dari pengumpul besar yang berasal dari wilayah Jawa Tengah, Maluku, dan Papua. Jenis pakan yang disukai oleh tokek dan cicak adalah jangkrik hidup. Pakan tambahan hanya diberikan pada jenis tokek bergaris. Upaya pemeliharaan kesehatan dilakukan setiap hari dan tidak dilakukan pemberian obat terhadap penyakit yang menyerang tokek dan cicak. Pemanfaatan hasil terhadap tokek dan cicak yang diperdagangkan hanya digunakan sebagai satwa peliharaan. Terdapat beberapa perilaku khusus yang diamati yakni meliputi aktivitas meluncur pada cicak terbang, aktivitas penumpukan pada tokek dan cicak, aktivitas memakan kulit yang terlepas (Shed skin), dan musim kawin.

Judul: Kajian Teknik Pemeliharaan dan Pertumbuhan Kura-kura di PT Mega Citrindo Parung - Bogor
Abstrak: Turtle has used by humans for food, medicine, education and pets. PT Mega Citrindo has used turtle for export as pets. This study aimed to assess the handling of turtle that has been carried out by PT Mega Citrindo. In addition, measure the growth rate of pig nose turtle (Carettochelys insculpta) and morphometry of the siebenrocki snake-necked turtle (Chelodina siebenrocki), parker’s snake-necked turtle (Chelodina parkeri) and reimann's snake-necked turtle (Chelodina reimanni). Data collected include data handling, growth and morphometry turtles. The types of handling data consisting of the cage, food, health, eggs and chicks, as well as utilization of the results. Data of growth include weight, length and width of the carapace pig nose turle (Carettochelys insculpta). While data of morphometric measurements taken on the carapace and plastron puck. The method used in this research is the field observations, interviews and literature. Field observations were used to obtain primary data. Interviews were conducted the officers and owners of captive breeding. While the literature study conducted on the technical aspects of breeding, growth and morphometry turtles. Then the data were analyzed by compiling the data in the form of tables and figures, so it can be concluded. Turtles can be kept in a plastic box and a permanent enclosure in accordance with the purpose of handling. This cage is cleaned every day or every other day to clean the cages of the remaining food and dirt. Type of feed given in the form of fruits and meat. Disease found on a turtle that is attacked by worms and fungi. The turtle is used have characteristics that is healthy and not disabled. The turtle packed with using cloth bags, plastic boxes and sectional. This company has been providing live animals are kept. The growth rate of pig nose turtle (Carettochelys insculpta) weight is 4,83 gram/month. The growth rate of length and width carapace are 1,2 mm/month and 1,3 mm/month. This is caused by environmental factors such as food, space and health. Siebenrocki snake-necked turtle (Chelodina siebenrocki), parker’s snake-necked turtle (Chelodina parkeri) and reimann's snake-necked turtle (Chelodina reimanni) can be distinguished by looking at the complexion of the head. Key features of this body can help in handling, breeding and utilization of results. Percentage length of the long neck turtle carapace type reimann's snake-necked turtle smaller than siebenrocki and parker’s snake-necked turtle. The male turtle have longer tail than female turtle.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
