Judul: Manajemen Penangkaran Kupu-kupu dan Tingkat Keberhasilan Pemeliharaan Troides helena di Alian Butterfly Park Kebumen
Abstrak: Taman Kupu-kupu Alian Butterfly Park Kebumen memiliki tujuan untuk konservasi kupu-kupu, wisata, pendidikan dan penelitian. T. helena merupakan salah satu jenis kupu-kupu yang ditangkarkan oleh Taman Kupu-kupu ini. T. helena merupakan salah satu jenis kupu-kupu yang dilindungi sehingga perlu dilakukan kajian terhadap pemeliharaan serta tingkat keberhasilan dari T. helena. Pelaksanaan penelitian meliputi pengambilan data manajemen penangkaran kupu-kupu dan pemeliharaan T. helena serta tingkat keberhasilannya. Pelaksanaan penelitian dilakukan dengan cara pengamatan pengukuran dan wawancara kepada pihak pengelola. Sistem manajemen penangkaran yang dilakukan Alian Butterfly Park adalah sistem intensif dan sistem semi intensif. Rata-rata persentase tingkat keberhasilan pemeliharaan T. helena mulai dari telur sampai dengan kupu-kupu di Taman Kupu-kupu Alian Butterfly Park adalah sebesar 6.67% yang dianalisa menggunakan tabel kehidupan. Fase paling rawan kematian pada proses metamorfosis kupu-kupu adalah fase ulat instar 4 dengan persentase keberhasilan 41.67% dan fase telur dengan persentase keberhasilan 53.33%.

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.
