Judul: Identifikasi Molekuler Undur-Undur Laut dari Perairan Pantai Cilacap Berdasarkan Marka Gen Cytochrome Oxidase Subunit I (COI)
Abstrak: Mole crab (Albunea symmysta) as an infaunal organism inhabits tidal-exposed sand sediment. Like other aquatic organisms, mole crab is destined to be cryptic species and complex species often leading to morphologically misidentification. Taxonomic identification for genus Albunea was uncertain due to variation in morphology. This study was aimed at identifying and analizing the phylogenetic relationship A. symmysta from Cilacap coastal waters based on molecular genetic marker Cytochrome Oxidase subunit I (COI). Isolation and extraction resulted in two intact DNA product which were amplified using universal COI primer. There were 650 bp nucleotide sequences. COI gene A..symmysta was aligned with other species catagorized as ingroup and outgroup (family Hippidae) acquired from GenBank. Alignment was performed using MEGA 5.0 software. Construction of phylogeny tree showed distinction between Albuneidae and Hippidae. There were 158 specific nucleotides in A. symmysta.

Judul: Karakteristik Gen Cytochrome Oxidase Subunit I (COI) pada Kerang Bulu (Anadara antiquata Linn.) asal Perairan Panimbang dan Bojonegara, Provinsi Banten
Abstrak: Anadara antiquata is an intertidal bivalve belongs to Arcidae Family. Its distribution in Indonesia is widespread. Its play role both in economy and ecology. Based on genetic database from GenBank, there is no genome data of A. antiquata from Indonesia. Therefore, to accomplish information on this hairy cockle, this research was aimed at characterizing cytochrome oxidase subunit I (COI) in cockle (Anadara antiquata linn.) from Banten (Panimbang and Bojonegara). Hairy cockle samples were collected from Panimbang and Bojonegara. Those were extracted for DNA analysis. DNA extraction and amplification process were followed with DNA sequencing of COI gene that produced 607 nucleotides (nt). The product was analyzed using software MEGA 4.0 and aligned with some sequences from GenBank database. This study was able to characterize A. antiquata COI gene which product was 382 nt using alignment method of Clustal W.

Judul: The Model of Physical Exercise Effect on the Dynamics of Glucose and Insulin
Abstrak: Regular physical activity is indicated either to prevent or delay the onset of non-insulin-dependent diabetes or to assure a good control of diabetes by increasing insulin sensitivity and ameliorating the metabolism of glucose disappearance. A minimal model developed previously was extended to include the major effects of exercise on plasma glucose and insulin levels. Minimal model of glucose and insulin dynamics created in this study is valid. Result of model simulation is good agreement with experimental data. On the normal subject, physical exercise can reduce blood glucose levels, the same thing happened in people with diabetes. In general, the model can be explained that physical exercise can lower glucose levels basal while after the exercise, but will eventually rise returned to initial basal glucose levels, so to keep the blood glucose remained normal should be done exercise regularly and with the assistance of insulin therapy appropriate to the needs of patients.
