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: Pemeliharaan Labi-labi (Amyda cartilagínea Boddaert, 1770) dan Uji Coba Preferensi Pakan Anakan di Penangkaran PT. Ekanindya Karsa, Kabupaten Serang
Abstrak: Softshell turtle (Amyda cartilaginea Boddaert, 1770) is categorized as Appendix II CITES and vulnerable in IUCN Red List Data Book. Captive breeding of this turtle is important to continue their sustainable utilization. PT Ekanindya Karsa was one of the pioneer in captive breeding of this species since 2008. Until now, there reference related to management and maintenance techniques of softshell turtle in captivity are few. This research aims to asess the characteristics of softshell turtle in captivity, document the management and maintenance techniques and analyse feeding preferences especially juveniles. The results will assist wildlife conservation efforts and improve it for the future. Research was carried out at PT. Ekanindya Karsa from July to October 2012. Data collected includes characteristics of shoftshell turtle, which consists morphometry and morphological of shoftshell turtle, maintenance of turtle in captivity and foods preference of juveniles. Nine adult shoftshell turtle (3 males and 6 females), 25 shoftshell turtle eggs, and 45 juveniles between 1 - 3 months were observed. Food tested comprises of tuna, shrimp, spinach and sweet potatoes which are given to 15 juveniles. Level of food intake, growth, cost efficiency and activity of juveniles were measured to assess ideal feeding time with focal animal sampling methods. Mean curved-carapace length of an adults (CCL) is 43.33 cm, curved-carapace wide (CCW) 35.33 cm and body weight 10.11 kg. Juvenil non test consists of three clutches with range of CCL is 4.21 - 4.68 cm; CCM is 3.68 - 4.24 cm and body weights of 9.95 – 12.59 g during hatching. Softshell turtle’s eggs had range of diameter of 2.84 - 3.95 cm and weight of 12.00 - 24.00 grams. Maintenance of turtle in captivity is quite well includes aspects of habitat maintenance, management of food and handling of eggs. However, diseases management has not been handled correctly in the captivity as shown by some untreated diseased adult. Preferred food of 15 juveniles were sweet potato and tuna. Feeding activities were visible in the morning (7.00 – 10.00 am) and evening (7.00 – 10.00 pm).

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.
