Pertumbuhan Bakteri Anaerobic Ammonia Oxidation (Anammox) Pada Salinitas 2 dan 9 Persen Wijanarka Wijanarka; Sudarno Sudarno; Novi A. Pratama
Jurnal Biologi Papua Vol 9, No 2 (2017)
Publisher : Jurusan Biologi FMIPA Universitas Cenderawasih

When ammonia in waste water is lost inappropriately, it will raise an adverse environmental effect for the aquatic cycle. Anammox, anaerobic ammonia oxidation, is a novel process in which nitrite is used as an electron acceptor in the conversion of ammonium to nitrogen gas. The anammox process removes ammonium in the autrotrophic system by leaving little biomass. This study aims to analyze the effect of salinity on the growth of anammox bacteria. The samples used were from the brackish water sediments of the East Flood Canal River of Semarang. The isolation was done by gram staining and the bacteria were inoculated on media with different salinity concentration and the growth was measured using spectrophotometer. The results showed that anammox bacteria had a higher growth rate of 3% (control) when it was grown on a medium with a concentration of 9%. Anammox bacteria grown on anammox selective media showed that the bacteria were able to adapt to environments with different salinity concentrations of 2% and 9%. Key words: anammox, ammonium, nitrogen, anammox bacteria.

Matoa (Pometia pinnata) is parts of Sapindaceae family widely spread in tropical areas, especially in Papua. Several studies mentioned the use of its parts as antioxidants and contain phenolic compounds and flavonoids. This study aim(s) to conduct a phytochemical screening test as well as a cytotoxic test for Pometia pinnata leaves fraction using the BSLT method. The research series began with the extraction process using 96% ethanol, then fractionated using three solvent variations: n-hexane, ethyl acetate, and ethanol. Further, the phytochemical screening test was carried out for cytotoxic testing in order to see the mortality rate of shrimp larvae Artemia salina Leach. The result of the phytochemical showed that the secondary metabolite compounds on the ethanol and ethyl acetate fraction were alkaloids, flavonoids, saponins, tannins, and terpenoids compounds meanwhile the n-hexane fraction contained terpenoids. The results of cytotoxic testing BSLT showed the LC50 value in the n-hexane was 7029.10 ppm, 406.07 ppm for ethyl acetate and 614.47 ppm for ethanol. Thus, it could be said that ethyl acetate and ethanol fractions were classified as a toxic category, while n-hexane was classified as a non-toxic category.Key words: matoa; fraction; phytochemical screening; cytotoxic.

Endomycorrhiza palys important role in nutrient uptake of agricultural plant. The purpose of this study was to investigate the presence of endomycorrhiza associated with non-legume plants, i.e.:Zea mays L., Solanum lycopersicum L., Capsicum frutescens L., Brassica oleracea L. and Brassica juncea (L.) Czern, in agricultural area in Koya Barat, Jayapura. Survey was done before collecting root and soil samples. The root of those non-legume plants were cleaned and stained using method developed by Kormanic and Mc.Graw. Wet seaving method was done to analyze soil samples. The result showed that those non-legume plants were infected by endomycorrhiza. The highest infection percentage was on corn (Zea mays L.), while the lowest was on cabbage (Brassica oleracea L.). Furthermore, from spore identification, 14 species of endomycorrhiza were found on the rhizosphere of those plants which were grouped into genus Glomus (5 species), Gigaspora (2 species), Acaulospora (2 species) and Scutelospora (1), however 4 species were remain unidentified yet. Therefore further study should be done to elucidate this problem.Key words: endomycorhiza, exploration, non-legum, Koya Barat, Jayapura.
