Abstract

This study was to obtain the description of tropical lowland forest of Papua in Sewan village, Sarmi District, Jayapura region. The main objective was to investigate the structure, species composition and ecological value of the forest vegetation. Research methods included line transect, documentation, interview and literature review. Index Shannon Wiener was used to determine the level of species diversity. The results revealed that 27 tree species that grouped into 17 families inhabited the study area. The density of trees was 209 individuals/ha. A number of saplings were identified into 17 species and grouped into 15 families with the density 104 individuals/ha. At the tree level, species with the high important value (IV) index. important value (IV) index were Pometia pinnata Forst. (54.31%), Macaranga gigantea M.A. (45.33%), Knema sp. (27.37%), Nauclea orientalis L. (20.69%), Intsia palembanica Miq. (13.86%), and the other species had lower INP. At the saplings level species that had high INP were Pometia pinnata Forst. (84.05%), Horsfieldia sylvestris Warb. (34.87%), Knema sp (25.92%), Celtis nerifolia (22.54%), and Pterocarpus indicus Willd. (18.12%). Diversity index at tree level and saplings level were 2.73 and 1.91 respectively, and this showed the high diversity of the trees compared to that of the saplings. The ecological value of the forest in Sewan village included the function as watershed area, buffer zone for the wildlife and as habitat for several fauna especially birds and bats. Key words: analysis of vegetation, species of trees, Sewan village, Sarmi.

Abstract

This study was conducted to identify the mesofauna inhabiting the reclamation area (Grasberg) and the natural succession (Ertsberg), to observe the development of mesofauna and to know the species compotition in the given area. Research method was pitfall trap that set up in reclamation area, natural succession and in control area. The result revealed that mesofauna in reclamation area were dominated by the family Isotomidae and Neelidae (Ordo Collembola) with the relative dominancy value 23,90% and 24,37% respectively, the presence or relative frequency 9,23% and 9,23%, and relative density value 23,90% dan 24,37% individuals/m³. Mesofauna in succession area Ertsberg were dominated by the family Neelidae (Ordo Collembola) with the relative dominancy value 31,85%, the presence or relative frequency 5,41% and relative dencity value 31,85% individual/m³. The dominant mesofauna in control area was famili Neelidae (Ordo Collembola) with the relative dominancy value 22,5%, the presence or relative frequency 4,17%, and the relative density value was 22,5% individual/m³. Phylum Arthropoda dominated the whole study area with the total individual 2089, whereas Phylum Annelida consisted of 33 individuals. The highest species composition was found in Menado Leach Pad (509 individuals) followed by Jayapura Crusher (322 individuals) and Ertsberg Lower (301 individuals). Species composition of mesofauna in the study area was generally grouped into two phyilum; Arthropoda and Annelida which consisted of 4 classes, 13 ordo, 38 families and 2122 individuals. Environmental recovery undertaken by the Freeport Company through reclamation and natural succession was successfully done as indicated by the occurrence of various vegetation and mesofauna that interact each other.Key words: Mesofauna, reclamation area Grasberg, natural succession Erstberg, Freeport Company, Timika.

Abstract

This study carried out at Laboratory of Biology, Division of Food and Cultivated Plants Protection, Jayapura from January-June 2008. The objective of this study was to examine the effect of citric acid (CH3COOH) concentration on rate of growth and spore production of Beauveria bassiana (Bals.) Vuill. strain Wamena which grow in short grain rice (beras pera) media. Six different concentration of citric acid (CH3COOH)  were 0; 0,025%; 0, 05%; 0,075%; 0,1% and 0,125% with 5 replicates for each concentration, complete random design were used. Result of this study showed that 0.05% of citric acid significantly affected spore production which mean potential  for biological  control  agent. Key words: Beauveria bassiana (Bals.) Vuill Strain Wamena, rice medium, biological control agent.

Abstract

This study was conducted to examine the effect of “keben” seed Baringtonia asiatica (L.) Kurz on mortality of flea (Coccus viridis) found in Coffea sp. Experimental methods with Complete Random Design (CRD) was used in this study. Five doses of “keben” seed extract (0.2%, 0.4%, 0.6% 0.8% and 0.0%) were used. Result of the study showed that all five concentration of “keben” extract were toxic to Coccus viridis, therefore can be used to control pest of coffe caused by Coccus viridis. Among the concentration used, it was found that concentration at 0.4% more effective than other concentrations. Consentration at 0.4% was killed 100% of Coccus viridis population in 3 days.Key words: Barringtonia asiatica, Coccus viridis, Concentration of seed extract.

Abstract

Study on the used of medicinal plants by Marind people who lived at Wasur National Park, Merauke was conducted by using descriptive methods which include observation, interview, documentation, literature review techniques, as well as  emic and ethic approaches. During the study there were 46 species which belong to 26 families plants found as medicinal plants used by Marind people to cure about 30 diseases. Among 46 species, there were 7 potential medicinal plant species which known  and used by most Marind people. The seven potential medicinal plant species were Ipomoea triloba L., Bauhinia sp., Pittosporum sp., Kingiodendron platycarpum Bent., Sophora tool mentosa L.Cyrtandra sp., dan Tinopspora disstiflora L. Part of plant used vary from leaf, root, bark, fruit and other part of plant. Compare to other part of plant, leaf was the most common used as traditional medicinal plant. Key words:   traditional medicinal plant, Marind people, Wasur National Park

Abstract

The aim of this study was to observe the presence of coliform bacteria and the level of contamination in outlet water of Sentani lake, especially in Jaifuri river. The study was done from Januari-April 2009 in 3 sampling areas: outlet of the lake (A), in between outlet and the river (B), and in Jaifuri river (C). Samples then be analized in Biology Laboratory, FMIPA University of Cenderawasih using MPN (Most Probable Number) series 3-3-3. Furthermore, the result then compared with the quality standard of dringking water (Peraturan Menteri Kesehatan RI No 416/MENKES/PER/IX1990). The result showed that coliform of sample A was 9.300 MPN/ 100 ml, sample B was 4.300 MPN/100 ml and sample C was 24.000 MPN/ 100 ml. That condition was above the maximum level of contamination of dringking water (0/100 ml). In addition, the biochemical test showed that Escherichia coli and Klebsiella pneumoniae were found in that water samples.  Key words: Coliform, Escherichia coli, outlet of Sentani lake, Jaifuri river, East Sentani.
