Sampare (Glochidion sp., Family:Â Phyllantaceae) is a plant which grows dominant in Biak, Papua. Based on the local wisdom of the community, by hereditary, it can be used as an herbal medicine to treat the malaria disease. This study aims to determine the toxicity of LC50Â and to know the phytochemical compounds of extracted leaf of Glochidion sp using ethanol. The Brine Shrimp Lethality Test (BSLT) and phytochemical screening using reagent chemical substance methods were used in this research. The results of this study can be concluded that the toxicity of extracted leaf of Glochidion sp. using ethanol was low, with LC50Â = 758.58 ppm and the results of phytochemical analysis showed the existence of the content of alkaloids, flavonoids, saponins, tannins and quinones. But, the steroids and triterpenoids could not be found in the extracted leaf of Glochidion sp using ethanol. Therefore, for further research is needed to isolate the bioactive compounds and in vivo test on the plasmodium, which cause the malaria disease.Â Key words: Glochidion sp., malariaÂ desease, Brine Shrimp Lethality Test (BSLT),Â LC50, phytochemical analysis

When ammonia in waste water is lost inappropriately, it Â will raise an adverse environmental effect for the aquatic cycle.Â Anammox, anaerobic ammonia oxidation,Â is a novel process in which nitrite is used as an electron acceptor in the conversion of ammonium to nitrogen gas.Â The anammox process removes ammonium in the autrotrophicÂ system by leaving little biomass.Â 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.Â The isolation was done by gram staining and the bacteria were inoculated on media with different salinity concentration and the growthÂ was measured using spectrophotometer.Â 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%.Â Key words: anammox, ammonium, nitrogen, anammox bacteria.

Sea cucumber is one of high value economic commodity due to not only having a fairly completedÂ nutrition,Â but also used as the raw material for production of drugs, cosmetics and others. Therefore it becomes one of the highly potential export commodities. However, the target of catching sea cucumbers community intensively will give a negative impact on its sustainability. Sea cucumber has long been recognized and protected by the people in Padaido islands known as sasisenÂ or sasiÂ system. Although it has been conserved through sasisenÂ system, but tends decline recently.Â ThisÂ happenÂ due to the high fishing activities by fisherman. Sea farming methods is a sea fisheries development concept in shallow waters such as the merger between aquaculture and capture fisheries by utilizing leading commodity in potential cultivation area. Sea farming is a system of utilization of marine ecosystem-based marine culture with the ultimate goal to improve the stock of fish (fish resources enhancement)Â to the sustainability of fisheries and other marine-based activities such as ecotourism. This paper will discuss the development opportunities of sea farming system that is integrated with the prevailing of local wisdom in Padaido Islands, Biak Numfor Regency, Papua, namely sasisen. This systemÂ works in conserving sea cucumber resources and increasing incomes of local communities in PadaidoÂ island through the creation of alternative livelihoods specifically in sea cucumber cultivation. Therefore, these models and approaches can be considered to manage coastal and marine resources in a sustainable way in Padaido Islands, Biak Numfor Regency.Key words:Â Sea cucumber, sustainable management, sasisen, Padaido Islands.
