The level of contamination, bioaccumulation and potential trophic transfer of toxic pollutants known as brominated flame retardants (BFRs), such as polybrominated diphenyl ethers (PBDEs) and hexabromocychlododecanes (HBCDs), was examined in biota representing different trophic levels in Jakarta Bay. Various organisms were collected using several catching methods during July-August 2007 at eastern part of the bay and were analyzed for nitrogen (N) and carbon (C) stable isotopes, 14 PBDE congeners and three HBCD isomers using GC-C-IRMS, GC-MS and LC-MS/MS, respectively. Analysis of N and C indicated that the biota was composed by different trophic levels within the Jakarta Bay ecosystem. Concentrations of total PBDEs and total HBCDs varied according to species, ranged from 1.6 ng/g lipid wt. to 57 ng/g lipid wt. and below detection limit (nd) to 4.1 ng/g lipid wt, respectively. Furthermore, there was significant positive correlation between trophic level (TL) and concentration of PBDEs was found, but not HBCDs. Trophic Magnification Factors (TMF) values of PBDEs ranged 0.63–3.0 with only two congeners (BDE-47 and BDE–100) having TMFs greater than one.

Publisher : Pusbindiklat - LIPI

Imported soybean as raw material for making tempe was preferred than local soybean due to better qualities in colour and uniform seed size. This study was carried out to evaluate the physical, chemical and organoleptic properties of tempe derived from both local and imported soybean. Five local soybean varieties and an imported soybean were examined in this research. This study consisted of two steps: (1) making of the tempe from various of soybean variety; (2) characterizing the tempe such as the physical properties (density, texture, pH, yield), chemical properties (water content, ash content, protein, fat, carbohydrate), and organoleptic properties (colour, smell, flavour, preference). The result showed that tempe derived from local soybean had a better quality than imported soybean tempe for its physical, chemical and organoleptic properties. Galunggung tempe had the highest yield and Anjasmara tempe had the highest protein content. Based on organoleptic properties, it shows that Bromo tempe had the highest preference value.
