Judul: Butterfly’s Daily Activities of Troides helena (Linn.) in Insects Museum and Butterflies Park of Taman Mini Indonesia Indah
Abstrak: Troides helena (Linn.) is one of butterflies from Family Papilionidae which protected by law in Indonesia. Illegal export and increasing demand of this species caused an exploitation of its population in nature. Thus, need a conservation effort to guarantee its sustainability. Conservation success, mainly in preservation and utilization, need information about time utilization pattern of T. helena’s daily activities. Insects Museum and Butterflies Park of Taman Mini Indonesia Indah (TMII) provide artificial habitats of butterflies. Butterflies function in this park is as live butterflies demonstration and educational means of their life. Purpose of this study is to knowing about time utilization pattern of T. helena’s daily activities. Result of this research is useful to provide information about daily’s time utilization pattern of T. helena and provide time selection reference of butterflies demonstration as tourist attraction. This study conducted from July to November 2009 in Insect Museum and Butterflies Park of Taman Mini Indonesia Indah. Equipments used in this research were dry-wet thermometer, stopwatch, digital camera, butterflies and plants identification books, and butterflies marker. The method used is by focal animal sampling which done to 5 male and 5 female T. helena. Activities observation started at 07:00 WIB to 17:00 WIB with 5 minutes time interval. Data analyzed by T test. Highest time allocation of daily activities were roosting (515.46 minutes), flying (45.86 minutes), nectar-feeding (3.94 minutes) and interaction (1.65 minutes), respectively. Comparison between male and female T. helena based on T test’s result different significantly in interaction and descending activities. It’s caused by male activity which more active to seek couple than female. Active time of T. helena was in the morning and reach its peak at 10:00 to 11:00 WIB. Most of flying activity did at 09:00 to 10:00 WIB. Most of nectar-feeding activity did at 08:00 to 09:00 WIB. Most of interaction did at 10:00 to 11:00 WIB. Most of roosting activity started at 13:00 to 17:00 WIB. Copulation activity, averaged, did for 2 to 3 hours. Egg-laying of female couldn’t observed caused of that butterfly die. Factors of T. helena’s mortality in Butterflies Park were damaged wing and predation by predator such as chameleon, lizard, ant and spider. Best time for visiting to watch T. helena’s activity start from 09:00 to 13:00 WIB. Checking of Butterflies Park and expulsion of butterfly’s predator, critically needed to decrease mortality risk of butterflies.

Judul: Aktivitas Harian Troides helena dan Pemanfaatannya sebagai Objek Wisata di Alian Butterfly Park Kebumen
Abstrak: Alian Butterfly Park adalah taman kupu-kupu yang berada di Kebumen, Jawa Tengah, yang diresmikan pada Juli 2015. Taman Kupu-kupu telah berhasil membudidayakan berbagai jenis kupu-kupu, salah satunya yaitu Troides helena. Tujuan dari penelitian ini adalah untuk mengkaji aktivitas harian Troides helena, pemanfaatan souvenir kupu-kupu, serta karakteristik dan persepsi pengunjung di Alian Butterfly Park sebagai objek wisata. Manfaat penelitian ini untuk mengembangkan penangkaran kupu-kupu di Indonesia. Aktivitas harian Troides helena terdiri dari: hinggap (87%), terbang (11%), interaksi (2%), dan nectaring (1%). Aktivitas nectaring dan hinggap menunjukkan perbedaan waktu nyata antara jantan dan betina. Produk souvenir kupu-kupu yang dijual di Alian Butterfly Park terdiri dari gantungan kunci, pigura dan diorama. Jumlah dan model souvenir yang ada berdasarkan ketersediaan bahan baku. Motivasi kunjungan utama pengunjung yang datang karena tujuan rekreasi (47%). Media informasi yang dipandang paling efektif oleh mayoritas pengunjung yang datang adalah kategori keluarga/teman/saudara (31%). Saran penulis kepada pengelola adalah membuat media interpretasi, membuat program pariwisata, dan memfasilitasi media online.

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.
