Judul: Pengkajian Investasi Modal Usaha Perikanan Rakyat Jaring Udang dalam Upaya Pengelolaan Sumberdaya Udang di Perairan Sekitar Cirebon Utara, Jawa Barat'
Abstrak: Two main issues: - sustainability of shrimp fishing area at North Cirebon and surrounding area and - feasibility of various fishing units were analyzed with the application of bioeconornic model and invesment analysis. It was evident from bioeconornic point of view that exploitation level of shrimp resource in the study area has come to overfishing condition. The implication is that fishing effort on shrimp should be corrected. The correction should not be based solely on biological consideration but also on the tinancial/invesrnent assessment.

Judul: Studies on fishing unit investment for sustainable penaeid shrimp resource management in the Cirebon Waters, West Java
Abstrak: Penaeid shrimp production which collected from the Cirebon’s fishers estimated to be over fished, but the result of research indicates that by using bio economic model approach, the rate of shrimp resource exploitation at the present time (the harvest = 4 174 994 kg, the effort = 2 181 shrimp fishing units) are still safe from overfishing condition, so that investment opportunity of shrimp fishing units are able to be carried out. At the first priority (at the OD – optimasi dinamik regime), investment opportunity on shrimp fishing unit could be carried out up to Rp 5,613,665,696.01 equivalent to increase 306 new shrimp fishing units or to motorize 1247 shrimp fishing units which were not use the motor. At the second priority (at the MEY regime), investment opportunity on shrimp fishing unit could be carried out up to Rp 3,633,226,321.00 equivalent to increase 198 new shrimp fishing units or to motorize 807 shrimp fishing units which were not use the motor. At the third priority (at the sustainable regime), investment opportunity on shrimp fishing unit could be carried out up to Rp 6, 815,399,701.88 equivalent to increase 372 new shrimp fishing units or to motorize 1515 shrimp fishing units which were not use the motor. The investment opportunity on shrimp fishing unit have to give priorities to : (i) increases the services of fishing port infrastructure in accordance with Per.16/MEN/ 2006, (ii) motorizes of shrimp fishing unit which still not use the machine, and (iii) increases the quantity of shrimp fishing unit them selves.

Judul: Grup Abelian Berhingga dari Barisan Genomik DNA  (Deoxyribonucleic Acid)
Abstrak: Informasi genetik yang memprogram semua aktivitas sel terdapat dalam bentuk kode di dalam molekul DNA. Grup kodon dari basa nukleotida DNA {A, C, G, U} tidak dapat merepresentasikan daerah non kode dalam genom yang disebabkan oleh mutasi penghapusan serta penyisipan pada barisan genomik DNA. Dalam karya ilmiah ini grup kodon diperluas dengan menambahkan huruf O untuk menandakan mutasi penghapusan atau penyisipan pada kodon untuk semua triplet diperluas 1 2 3 X X X dengan i X Î{O, A, C, G, U} dari barisan genomik DNA. Grup kodon yang diperluas isomorfik dengan grup bilangan bulat modulo 125. Grup abelian berhingga dari barisan genomik DNA yang dibentuk dari himpunan seluruh pasangan terurut triplet ekson dan intron pada untai DNA isomorfik dengan grup jumlah langsung bilangan bulat modulo 64 dan 125. Kemudian grup abelian berhingga tersebut direpresentasikan sebagai grup jumlah langsung 2-grup dan 5-grup homosiklik. Bagian barisan genomik DNA tanpa penyisipan membangun blok gen yang direpresentasikan oleh 2-grup homosiklik, sedangkan bagian barisan genomik DNA yang dipengaruhi oleh penyisipan direpresentasikan oleh 5-grup homosiklik.
