Judul: Ekstraksi Inhibitor Protease dari Sponge dan Potensi Daya Hambatnya terhadap Protease Bakteri Patogen.
Abstrak: Semakin jelasnya keterlibatan enzim protease di dalam mekanisme molekular penyakit asal bakteri, virus, malaria, kanker, tumor, dan penyakit yang muncul baru-baru ini seperti SARS, bahkan penyakit degeneratif seperti Alzheimer menyebabkan meningkatnya perhatian terhadap protease sebagai target senyawa obat bagi penyakit-penyakit tersebut. Desain atau pencarian inhibitor spesifik atau senyawa anti protease target tersebut dapat dilakukan, untuk selanjutnya dikembangkan sebagai obat. Pencarian sumber inhibitor alamiah enzim protease kmi sudah merambah ke arah organisme laut. Diantara berbagai jenis organisme yang hidup di laut, sponge merupakan sumber yang paling produktif menghasilkan komponen bioaktif. Metabolit sekunder seperti terpenoid, alkaloid, peptida, bioaktif asam lemak dan steroid merupakan komponen yang umum terdapat di dalam sponge. Di pasaran, saat ini senyawa-senyawa potensial yang berasal dari sponge seperti Bastadin 5, Bastadin 19 dan Manoalide dihargai sangat mahal. Maka dari itu perlu dilakukan penelitian untuk mencari sponge laut yang potensial dan mengisolasi komponen inhibitor protease potensial yang salah satunya terhadap protease yang diproduksi oleh bakteri patogen penyebab penyakit.

Judul: Screening and characterization of protease inhibitor from  bacteria-associated with sponge, from pulau Panggang waters, Seribu islands
Abstrak: The important causing cause foodborne diseases are Staphylococcus aureus, Escherichia coli, Listeria spp. and Pseudomonas aeruginosa. Protease produced by these bacteria are involved in the molecular mechanisms of the diseases. Therefore, there has been rapidly increase concern on proteases as medical target for bacterium diseases. Various sponges has been reported to produce protease inhibitor which could inhibit protease activity of pathogenic bacteria. The previous research showed that bacteria-associated with sponge could produce bioactive compound similar with their host. Therefore, there is a possibility that the bacteria also produce protease inhibitor.

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.
