This study aimed at identifying chemical and microorganism contamination in foods of street vendors around Institut Agama Islam (IAIN) Syekh Nurjati Cirebon. The samples are meatball, cilok, grilled fish cake, nuggets, rolade, sauce, crackers, and iced water drinks. The sample tests are formalin test, borax test, Rodhamine B test, Methanyl Yellow test, and Coliform & Escherichia coli MPN test. The results showed that some food samples like meatball, cilok, grilled fish cake, nuggets,and rolade were positive of formalin & borax contaminated. The iced water drinks are contaminated by Coliform & E. coli. The other samples like sauce and crackers were negative of Rhodamine B & Methanyl Yellow contaminated. In conclusion, according to this study, the foods of street vendors at IAIN Cirebon are not yet safe to be consumed.

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.

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.

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.

All types of bivalves have the potential to produce pearls. Pearls can be produced naturally and cultivated. In cultured pearls, pearl sac are obtained from saibo (slices of another bivalve mantle) that which come from pallial zone. This study wants know the structures of tissues saibo of several species of bivalves as an alternative pearls implantation. This study is conducted from January to March 2017. This study used 7 types of bivalves among others; Pinctada margaritifera, Saccostrea cucullata, Asaphis violascens, Polymesoda bengalensis, Pinna muricata, Volachlamys singaporina, and Tridacna crocea. The method used by staining Hematoxylin-Eosin. Thisstudy show results that every saibo has the different characteristic, but has a common characteristic of having outer epithelium mantle, inner epithelium mantle, muscle fibers, connective tissue and longitudinal muscle, so it can be recommended in pearls implantation Keywords : Saibo, Bivalvia, Implantasi Mutiara[H1] [H1]Disusun berdasarkan abjad
所有类型的双壳类动物都有生产珍珠的潜力。珍珠可以自然生产和栽培。在人工养殖的珍珠中，珍珠囊是从来自Palial带的saibo（另一种双壳类外壳的切片）中获得的。本研究旨在了解几种双壳类动物的组织结构，作为珍珠植入的替代品。本研究于2017年1月至3月进行。这项研究使用了7种双壳类动物；玛格丽塔珠母贝（Pintada margaritifera）、葫芦花（Saccotrea cuculata）、紫锥藻（Asaphis violascens）、孟加拉多聚亚（Polysoda bengalensis）、黑锥藻（Pinna muricata）、单孔珊瑚（Volachlamys singaporina）和番红花（Tridacna crocea）。苏木精-曙红染色法。本研究结果表明，每个赛博都有不同的特征，但有一个共同的特征，即有外上皮套、内上皮套、肌纤维、结缔组织和纵肌，因此可以推荐用于珍珠植入关键词：赛博、双瓣、Mutiara植入[H1][H1]Disusun berdasarkan abjad
