Judul: Studi Histopatologi Insang, Usus Dan Otot Ikan Gurami (Osphronemus gouramy) Akibat Infestasi Parasit Protozoa Di Desa Carangpulang Dramaga Bogor
Abstrak: The aim of the research was to find out the histopathological lesions of gouranzy fish gills, intestines, and muscles from Carangpulang Village Bogor. Fifteen fishes about a year old wlere used as sample in this research. Histopathological examination was done by lzenzatoxiilin and eosin stain (HE). Microscopically, gill was the izostc ommon organ with pathological lesions. Gill was ofen infected by flagellum protozoa parrrsites, such as Ichthyobodo sp, Myxozoa (Hennegujla sp and Myxobolus sp) and unidentified protozoa. In intestines, no specijic pathological change was found, while in muscle tissue hyaline and vacuola degenerations as well as necrotic lesions were commonly detected. Based on all findings mentioned above, the lesion of gill fishes were inzcted by protozoa Ichthyobodo sp and myxozoa which can cause ichthyobodosis. Moreover, we suggest that a non infectious agent such as chemical polutans as one of the caused of oedema, telangiectasis and thickening of lamella of the gills.

Judul: Keberadaan Ektoparasit pada Gurame Osphronemus goramy Yang Dibudidayakan Secara Tradisional Serta Analisis Korelasi Aspek Biologi Inang-Parasit
Abstrak: Parasites belong to one of causative agent of infection diseases in goramy O. goramy. This study aimed to classifying the ectoparasites and analyze the correlation of biological aspects of host-parasite in goramy O. goramy from traditional farming. In this study, 348 fishes in sizes were used as the samples. The fishes were taken randomly from 71 traditional goramy farmers from seven sub districts in Bogor. The ectoparasites identified as Digenean Metacercaria, Chilodonella sp., Copepode, Dactylogyrus sp., Gyrodactylus sp., Glochidia, Henneguya sp., Icthyophthirius multifiliis, Tetrahymena sp., Trichodina sp., Oodinium sp., Piscinoodinium sp. , and Trematode. There are closed correlation between the body length with the presence of parasites in fish, whereas the Health Assessment Index (HAI) was not closely related with the number of ectoparasites found.

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.
