A part from its main product, meat, a slaughterhouse also produces by products and waste. The waste from slaughterhouse is categorized as organic waste, which is high in proteins, fats, and starches. This waste is potential as a source of pollutant. Slaughterhouse wastes can be treated by physically, chemically, and biologically.One of biological treatments is the use of water hyacinth (Eichhomia crassipes (Mart) Solm.), which is known to have an ability to remove organic and unorganic compound and heavy metals.The objective of this research was to evaluate the wastewater quality with water hyacinth treatment and to identify the interaction between action period and the density of water hyacinth during treatment. Four model ponds of 95 cm long x 50 cm wide x 50 cm high were used in this research. The parameters observed were pH, BOD5, and COD for the water quality. Each parameter was observed on day 0, 7, 14, 21, and 28, respectiv ely. The results of the research indicates that the water hyacinth had significant effect (P<0.01) on declining pH, BOD5 and COD of wastewater. The interaction between treatment and time observation lh showed significant effect (P<0.01) up to 28Ã day of observation.

POTENSI TRANSMISI VIRUS AVIAN INFLUENZA DARI BABI DAN UNGGAS PADA PETERNAKAN BABI DI WILAYAH TANGERANG, PROVINSI BANTEN [The potential of Transmission of aAvian Influenza Virus from Pig and Bird at the Pig Farm in Tangerang District, Banten Province] Dharmayanti, NLP Indi; Ratnawati, Atik

Pigs have an important role in the ecology of influenza virus since they are sensitive to influenza viruses from human and avian origin. Influenza A virus has a host specificity, although not absolute, so most of the AI virus circulating in various species is only limited to the species, but sometimes there are interactions between different AI virus species or strain. Farming systems that combine a variety of animal species together in the same or around the sites have an important role in the spread of disease and transmission between species. This study is aimed to investigate the cycle of AI virus in order to determine the potential occurrence of viral transmission among species pig and bird at the pig farm that also raising poultry. Influenza virus was identified by methods of RT-PCR and qRT-PCR. The results showed that the novel H1N1 pandemic virus was detected in one pig farm in Tangerang (Banten Province). The AI/H5 virus is also detected in the pig farm that also raises poultry or poultry/pig farmers and located adjacent each other. The AI virus / influence A is also detected in most of the pigs. Detection of AI viruses that infected in pig farm which kept birds or poultry farm around the pigs farm had potential of AI virus transmission from birds species to pig or vise versa. The pigs could serve as a mixing vessel, thus providing opportunities likelihood of reassortant viruses.

Pellacalyx is one of the genera in Rhizophoraceae, distributed from Myanmar, South China, Indonesia, Malaysia and the Philippines. In Indonesia, Pellacalyx can be found in the island of Sumatra, Kalimantan and Sulawesi. Eight species of Pellacalyx have been found Â in Indonesia, four of which them were from Kalimantan, i.e. P. axillaris, P. cristatus, P. lobbii and P. symphiodiscus. These four species generally grow in the primary and secondary forest, from lowland to an altitude of 1300 m above sea level. Information of Pellacalyx in Indonesia is still very limited , and rarely found in the wild. The last information of Pellacalyx found in West Sumatra was reported by an expedition team of the Center for Plant Conservation Bogor Botanical Garden in 2006. Â The Expert Team of the Khatulistiwa Expedition in Long Bagun, West Kutai, East Kalimantan on May 26âJune 2, 2012 found a species of Pellacalyx. Morphological characterization was then conducted based on the herbarium specimen for identification. The identification was carried out in Bogor Botanic Gardens, Center for Biological Research, Indonesian Institute of Sciences and The National Herbarium Leiden, Netherland. The results show that Pellacalyx specimen from Long Bagun is Pellacalyx symphiodiscus.Â
