Judul: Masalah infestasi ektoparasit pada reptilia di Kebun Binatang Ragunan Jakarta
Abstrak: Untuk memahami permasalahan yang ada di Kebun Binatang Ragunan tentang infestasi ektoparasit ini, telah dilakukan pengamatan pada satwa reptilia yang terdapat di dalam tiga lokasi terarium Kebun Binatang Ragunan selama bulan Oktober 1984. Metode yang digunakan adalah pengamatan secara langsung dan pengambilan data sekunder, berupa data dari laporan yang ada dan wawancara. Jenis ektoparasit yang terdapat menginfestasi reftilia di Kebun Binatang Ragunan ada empat jenis caplak, yaitu Aponomna lucasi, Aponomma barbauri, Amblyonuna helvolum dan Amblyomma cordiferum, Hasil pengamatan terakhir ditemukan Aponomma lucasi dan Amblyomma helvolum. Permasalahan yang dihadapi akibat infestasi caplak ini secara tidak langsung adalah kematian dari satwa reрtilia, juga infestasi caplaknya sulit untuk diberantas secara total.

Judul: Eksplorasi Cacing Endoparasit Saluran Pencernaan Satwa di Kebun Binatang Semarang
Abstrak: Zoo is the place where some animal species collected together in artificial environment. Parasites exploration in zoo needs to be done to monitoring of parasites spreading in animals zoo collection. This study aimed to explore the gastrointestinal endoparasitic worms of wild captive animals in Semarang Zoo. The flotation and precipitation methods were used to detecting presence or absence the gastrointestinal endoparasite of worm eggs in fecal samples. In Semarang Zoo there were 17 species (54.84%) out of 31 wild captive animals were found to be infected by parasites. Seventen genera of endoparasitic worms were determined after identification. The most common endoparasitic worms found in Semarang Zoo were Nematodes, followed by Cestodes and Trematodes. Endoparasitic worms found in mammals were Nematodes (Ascaris sp., Toxocara sp., Ancylostoma sp., Bunostomum sp., Oesophagostomum sp., Haemonchus sp., Cooperia sp., Trichostrongylus sp., Trichuris sp., and Capillaria sp.), and Cestodes (Spirometra sp., Taenia sp., Hymenolepys sp., Diphyllobothrium sp.). Meanwhile, in aves Nematodes (Amidostomum sp., Capillaria sp.) and Trematodes (Alaria sp.) were determined. Whereas only Nematodes (Rhabdias sp.) were determined in reptiles. Capillaria was the only parasite found in mammals and aves.

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.
