Bivalves include sludge animals scattered in coastal waters with sand and mud substrate. This study was to determined the structure of bivalves communities in the coastal waters in Dullah Village, Tual City. This study was conducted from December 2016 until March 2017 using plot method measuring 1x1 meter. This study was result found 576 individuals consisting of 4 orders, 10 families, 14 genus, and 15 species. The largest species are Anadara antiquata with total of 118 individuals and the least species are Mytilus sp with 1 individual. The structure of the bivalvia community in the coastal waters of Dullah Village is less stable because of its moderate diversity so that dominance is low. In the absence of dominating species, the fairness of bivalves is high.

Publisher : Universitas Tanjungpura

Pasak bumi (Eurycoma longifolia Jack.) is a species belonging Simarobuaceae has been long used as traditional medicine, which known very well as aphrosidiac. The studies have been conducted to reveal the benefits of E. longifolia through ethnobotany, phytochemical, and bioessay approaches, but the review articles on the its utilization and bioactivity limited. This article is based on scientific articles published on line or off-line, then synthesized so that to be information the relationship between use and bioactivity. Ethnobotany of E. longifolia have been used as a medicine for fever, malaria, improve stamina, antimalarial, antidiabetic, anticancer, aphrodisiac, overcoming erectile dysfunction. Bioactivity of E. longifolia is antiosteoporotic, antimicrobial, aphrodisiac, anticancer, angiogenesis, and hepatoprotective. Eurycomanone has activity as an antimalaria, antipyretic, aphrodisiac, and cytotoxic. The quassinoids, coumarin and glycosides of El have activity increase the production, quality, totality, synthesis and release of spermatozoa. Eurycoma longifolia is very potential to be developed as an antiosteoporotic and aprosidiac drug, but until now most of it is harvested directly from the forest, so to preserve it, we need to study the cultivation method.

Evaluation of liver and renal functions are routine tests performed in preclinical studies. Liver plays a role in detoxification and secretion of various substances to regulate a wide range of metabolic functions. Kidneys serves as the main excretory and osmoregulatory organs. Thus, assessment of liver and renal functions are important in identifying the presence of damages and diseases as well as monitoring body responses towards treatments or therapy. Therefore, normal values should be established for valid reference. Until now, many researchers still use references from various publications, including foreign countries with different environmental factors and method of animals care. This study was aimed to provide reference values for liver and renal functions in male and female Wistar rats. Animals were sourced from LPPT-UGM. Age 4-, 6-, and 8-week-old represent juvenile, preadult, and adult. Blood samples were collected from orbital sinus of anesthetized animals. Sera were tested for ALT, AST, BUN, and creatinine based on spectrophotometry. Results demonstrated that values of most parameters varied, depend on sex and age. According to this finding, it can be concluded that reference values cannot be generalized but must be determined by sex and age in local population.
