Judul: Studi Patologi Kerang Hijau (Perna viridis) asal Muara Kamal, Teluk Jakarta
Abstrak: Green mussel (Perna viridis) is a filter feeder organism that is abundant in nature and have a long life span. The mussel have become a biologic indicator for environmental contamination. Pathological conditions caused by environmental contaminants and infections can be observed by staining the tissue section. The aim of this study was to observe histopathological finding of green mussel cultured at Muara Kamal, Jakarta Bay. Twenty one green mussels of various size and age were observed. The lesions found were degenerative lesions such as pigmentation and loss of epithelial cilia. These lesions were considered due to low heavy metals contamination since the measurement of Hg, Pb, and Cd level still in the normal range. Hemocytes infiltration observed in some tissue were thought as body defense reaction. The protozoan Nematopsis spp. infection were detected in gills lumina, connective tissue of mantle and within digestive tract.

Judul: Kandungan Hg dan Pb dalam daging kurang hijau (Perna viridis Linnaeus) serta kondisi lingkungan budidayanya di perairan muara kamal,Teluk Jakarta
Abstrak: Perairan Muara Kamal rnempunyai arti penting bagi rnasyarakat setempat dengan peranannya sebagai sumber perikanan dan ternpat pendaratan ikan. Dilain pihak perairan tersebut juga merupakan tempat masuknya bahan buangan yang datang dari daratan baik secara langsung maupun tidak yang dibawa oleh aliran Sungai Cikarnal. Hal ini, dapat menyebabkan menurunnya kualitas lingkungan perairan. Pada awal tahun 1993 muncul kegiatan baru yang dilakukan oleh nelayan bagan di Muara Kamal yaitu membudidayakan kerang hijau (Perna viridis L.). Oleh karena itu perlu dilakukan pengkajian terhadap kualitas lingkungan perairan serta kandungan logarn berat dalarn daging kerang hijau tersebut. Tujuan penelitian ini ialah untuk mengetahui kualitas perairan, kandungan Hg dan Pb dalarn daging kerang hijau, serta pengaruh pencemaran perairan terhadap kondisis sosial ekonomi masyarakat setempat. Hasil penelitian ini diharapkan dapat bermanfaat bagi upaya pernantauan pencernaran perairan serta serta pengelolaan sumberdaya perikanan dan usaha perikanan. dst ...

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.
