Abstract

Dianella nemorosa Lam. was known containing alkaloids, terpenoid, phenolic compouds and tanin. Antiproliferative effect of D. nemorosa leaves methanol exctract, which demonstrated to have an in vitro cytotoxic effect on cancer cell line. The aim of research was examined the effect antiproliferative methanol extract of D. nemorosa leaves against MKN45 (gastric cancer) cell line. Leaves powder extracted using methanol. Antiproliferative effect was determined by Cell Proliferation Reagents WST-1 ((2-(4-iodophenyl)-3-(4-nitro-phenyl)-5-(2,4-disulfophenyl)-2H-tetrazolium monosodium salt). Test for 1h, 2h, and 4h after incubated for 72h was done. The result of this research showed that methanol exctract from D. nemorosa possessed remarkable no had antiproliferative activity against MKN45 cell line. The result indicated methanol extract of D. nemorosa leaves selective inhibitory effect or antiproliferative against cell line. Key words: Dianella nemorosa, Antiproliferative, MKN 45, and WST-1

Abstract

Pneumonia is the leading cause of death among children worldwide. It causes more death than any other diseases, even AIDS and malaria. One of five children under the age of five died of pneumonia and over two million children around the world died of it each year.Pneumonia generally caused by infection, lungs become inflamed and congested, reducing oxygen exchangeandleading to cough and breathlessness.. In developed countries, deaths from pneumonia have been reduced by improvements in living conditions, air quality and nutrition. In the developing world today, many deaths from pneumonia are also preventable by immunization.Key words: children, pneumonia, immunization.

Abstract

The determination of antimicrobial and antioxidant activities of Chlorophyll pigment of Caulerpa racemosa (Forsskal) J.Agardh is described in this study. The aim of the study was to find out the effectiveness of chlorophyll extract in inhibiting growth of Staphylococcus aureus and Escherichia coli. Paper disc method was used to study the hampering the ability of chlorophyll toward both bacteria, and the DPPH (1,1-difenil-2-dipikrilhidrazil) method was used to find out the antioxidant activity. The result showed that extract chlorophyll can inhibit the growth of both bacteria at the concentration of 100% with the inhibition diameter zone 2.170 cm and 2.100 cm respectively. Whereas the IC50 of the chlorophyll is 2350.3 ppm can be served as an antioxidants.   Key words: antibacterial, antioxidants, chlorophyll, Caulerparacemosa (Forsskål) J.Agardh.

Abstract

Lake Sentani has been subjected to multi-pronged  pressures, involving both internal and external factor.  Yet, ecologists researching the lake generally, conduct studies on water quality, but less attention was paid towards faunal diversity and biological resources potentials of the lake. This research is focused on the diversity of Thiaridae species (Gastropoda). The research was conducted for two months from October to November 2009 using line transect methods in settlement and no settlement areas, inlet and outlet areas. The transects was installed in the lake from the shoreline at 0 to 0.5m depth  and 0.5 to 1.0m depth  and 1.0 to 1.5 m depth. At each depth sample, 4 points were taken. Transect at each location, repetition was  repeated 4 times. The results brought in the diversity of Thiaridae as 7 species, namely Tiara scabra and Melanoides granifera, Melanoides tuberculata, Melanoides canalis, Melanoides copali, Melanoides sentaniensi, Stelomelania sp. The highest diversity were found in no settlement region with a value of H was 0.65 and the lowest were found in residential area with a H value was 0.57, inlet area was 0.59 and outlet area was 0.34. Density in no settlement areas was 0.36, inlet area was 1.84 and outlet area was 0.64. Environmental parameters was also assessed in this study, such as temperature, pH, DO, phosphorus, nitrite and nitrate. Key words: threat, Lake Sentani, diversity, density, Mollusc.

Abstract

Papua has a potensial marine resources both in ecology aspect as well as in economic. To keep the richness of marine resources, conservation is needed. Tiyaitiki is a traditional conservation based on indigenous knowledge of local people of Teluk Tanah Merah Depapre Jayapura. They used their custom to conserve both the water areas and the natural resources as well. The aims of the study were to observe the diversity of plankton and fishes in Teluk Tanah Merah, and to know the quality of water based on that diversity. Research was conducted from July to August 2007.  Line transect method was used in this study. Datawere collected from three station,  at morning, noon, dawn and night separately.The result of the study were 38 genera of plankton, 21 genera of fithoplankton and 17 genera of zooplankton. Moreover, the result of fish diversity survey was 62 species. Those indicated that the water areas in Teluk Tanah Merah Depapre was in a good qualityfor fish life. Key words:  plankton, fish, Tiyaitiki, Jayapura, Papua
