Abstrak: This study aims to determine and analyze the management of the breeding success rate of butterflies in PT Ikas Amboina and the Bali Butterfly Park. It is expected that this research can be an input for the PT Ikas Amboina and the Bali Butterfly Park itself in order to develop cultivation techniques and theutilization of butterflies better yet ,in addition this research also to expected to serve as guidelines for the management and or development of captive breeding butterfly elsewhere in Indonesia. This research was conducted through five stages namely study literature, measurements, observations, and interviews, as well as qualitative data processing. From the research result shows there are 15 species of butterflies that captived, consisting of two families namely Papilionidae and Nymphalidae. Two species of family Papilionidae including a protected butterfly, Ornithoptera priamus and Troides helena. There are five types of cages used during the captive process of butterflies, among other reproductive cage, cage rearing the eggs, the larval rearing, cocoon cage, and cage of butterflies. Plants used in the process of cultivating a butterfly on the basis of its functions can be divided into three, namely feed the larvae, the main plant (nectar-producing), and supporting plants (ornamental). Management conducted in captivity include the procurement of seed, maintenance of egg, larval rearing, maintenance pupa, maintenance of adult butterfly, health care, provision of additional food, and utilization of butterflies through activities of captive offset creation. Butterfly farming techniques are carried out intensively by PT Ikas Amboina able to increase the odds of living butterflies, which average 53.17% of the total eggs produced.

Judul: Manajemen Penangkaran Kupu-kupu dan Tingkat Keberhasilannya di Taman Kupu-kupu Cihanjuang Bandung
Abstrak: The purpose of this study are knowing the management and the success rate of butterfly captivity at Cihanjuang Butterfly Park. The used methods were field observation, interview and study of literature The success rate of the captivity was measured by the percentage of an amount that is born over the amount which fails on each phase of life. The result of the study showed that management of captive was done as semi-intensive by dividing the captives base on life phase of butterfly and selectig plants was adapted by the species of the butterfly. Troides helena helena use „sirih hutan‟ (Aristolochia tagala) as host plant. The average feed consumed during worm phase of Troides helena helena was 19.04 gram. The success percentage of Troides helena helena captivity was 36.7%, it meant medium category (30-60%), whereas the success of the Cihanjuang Butterfly Garden overall by 22.93%, was low (<30%).

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.
