Pegunungan Bintang is one of new regencies in Papua Province which was used to be part of Jayawijaya regency. In connection with the development of a new region there are many forest areas had been converted to infrastructure development. Those conversion has adverse impact on the presence of flora and fauna including orchids in the areas. Therefore this study was done to obtain the information about the diversity of orchids species at forest area of Oksibil District, Pegunungan Bintang, Papua. The study was conducted in seven of ten villages including Oksibil as the capital city of Pegunungan Bintang. The result showed that there are 9 genera consist of 23 species of both epiphytic and terrestrial orchids. Dendrobium and Agrostophyllum are more frequently found than others. Among them only few species has been collected by the local people without proper propagation. Key words: Orchids, diversity, Oksibil, Pegunungan Bintang.

Tropical rain forest of Papua is very diverse in its floristic composition. Increasing human population cause the loss of forest for farming, urban areas or other human activities which cause deforestation. The objective of this study was to obtain the description of composition and structure as well as ecological value of forest area at Tablanusu Village, District of Depapre. Study was carried out from January – June 2009. Quadrat plot (50 m x 20 m) were placed at 30 m a.s. l and 200 m a.s.l. . Index of Shannon-Wieners was used to determine the level of species diversity and Index of Similarity to indicate degree of similarity of composition between two different altitudes. Results of the study revealed that at 30 m a.s.l occupied by 25 species that grouped into 18 families of trees (ø > 10 cm) with total 146 trees., sapling (ø 2-10 cm) was consisted of 26 species of 15 families and 74 individuals. While at 200 m asl, there were 18 species of tress (ø > 10 cm) which grouped into 13 families with 93 individuals, 23 species of sapling (ø 2-10 cm) that grouped into 20 families with total number of individu was 82. The value of Similarity indices of the tree at 30 m asl and 200 m asl was 0%, on the other hand for sapling its value showed 12,24 %. It means that there was a differences in the species composition on both areas. Furthermore, the species wich has highest Important value at 30 m asl was Cocos nucifera L. (63,84 %) for trees and Kleinhovia hospita L. (37,61 %) for sapling. While at 200 m asl, this highest value for trees was found in Instia bijuga OK. (81,67 %), and Mastixiodendron pachyclados K.Sch (41,31 %) for sapling. Eventhough the regeneration procees in those forest was slow, but it has high ecological value, for example as water suply, preventing erotion, habitat of fauna and maintaining the microclimate. Keywords : analysis of forest vegetation, tree species, Tablanusu village, Depapre.

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.

The mycorrhizas are ‘balanced’ mutualistic associations in which the fungus and plant exchange commodities required for their growth and survival. The are many type of mycorrhizal namely endomycorrhiza, ectomycorrhiza, Orchid-mycorrhiza, ericoid mycorrhiza, and ectendo mycorrhiza. Most research is in endo and ectomycorrhiza, due to their role in Papua. Research in mycorrhiza has also been done recently. The research started in 2005 with ectomycorrhiza studies conducted by Suharno & Sufaati. Study on endomycorrhiza were begin in 2006 and orchid mycorrhiza in 2007. Exploration study of endomycorrhiza in corn plant at Koya Barat showed that there were 7 species of VAM namely Glomus sp1., Glomus sp2., Glomus sp3., Gigaspora sp., Acaulospora., Scutellospora sp1., and Scutellospora sp2. Similar research have also been done on other agriculture comodity, and the weed as well. Study on the endomycorrhiza associated with matoa (Pometia pinnata) found 13 species. Furtheremore, preliminary research on ectomycorrhiza showed that at least four species have been found at Mount Cycloops Nature Reserve, Jayapura. In Papua, there were 18 strain isolate of Scleroderma have been collected and 4 species were already identified. For orchid-mycorrhiza there were only 17 species has been found so far. Among them there species were identified: Rhizoctonia sp., Tulasnella sp., dan Ceratorhiza sp. The potency of mycorrhiza in Papua is high and need to be explored. Some isolate were already tested to variety of the growth of plant. The result showed that the isolate affected significantly. More exploration, compatibility test, and the role of mycorrhiza will be continued to study. The goals of all the study here was to find a good quality of isolate that can be used as a propagule to produce biofertilizer.Key words: endomycorrhiza, ectomycorrhiza, orchid-mycorrhiza, biofertilizer, Papua.

Keragaman Burung Pemakan Buah (Avian Frugivora) di Hutan Dataran Rendah Jayapura, Papua Margaretha Z. Pangau; Supeni Sufaati

Frugivorous birds or avian frugivores play important role in seed dispersal cycle and forest regeneration in forest ecosystem of Papua. Despite the high diversity of avian frugivores dwelling in Papuan rainforest, and the fact that this region faces alarming rate of forest disturbance, little is known of their current presence in the lowland forest habitat. We surveyed the variety of frugivorous birds in three different habitats of lowland forest in Cyclop Mountains Nature Reserve and Nimbokrang District. The methods used were line and point transects and identification was done during the survey. A total of 36 frugivorous birds from eight families was found in both sites. There were 33 species of 8 families in Nimbokrang forest and 16 species of 7 families were encountered in the Nature Reserve. The primary forest has high diversity of frugivorous birds compared to that in secondary forest and forest garden. It was found that several species of Family Columbidae such as Macropygia amboinensis, Ducula pinon dan Reindwaedtoena reinwardtii moved and foraged along the forest edge and also visited degraded areas that still provided vegetation trees and perches. These findings might have importance for forest management and reforestation programmes in Papuan lowland forest.Key words: Frugivorous birds, diversity, lowland forest, Mountain Cyclops Nature Reserve, Nimbokrang.

Peranan Fungi Mikoriza Arbuskular (FMA) dan Serasah Daun Gamal (Gliricidia sepium L.) terhadap Pertumbuhan Bawang Merah (Allium cepa L.) pada Tanah Podzolik Merah Kuning Supeni Sufaati; Rr. Evi D. Aryuni

The aim of study was to know the effect of Arbuscular Mycorrhiza Fungi (AMF), Glomus mosseae on the growth of onion Allium cepa L. on red-yellow podzolic soils. Completely Randomized Design (CRD) factorial with 10 replicates was used in this experiment. The first factor was mycorrhizae, with two level: without inoculation as a control (M0); 10 gram inoculation = M1). The second factorwas leaf litter of gamal Gliricidia sepium L. species wich were no litter as S0; 5 gram litter = S1; S2 was 10 gram of litter; and 20 grams of loitter in one kilogram of soil separately. Parameters used in this study were the growth of onion that has infected root in percent, and Relative Growth Rate (RGR). ANOVA was used to analyze the data, and followed with DMRT at 95% level test. The result showed that mycorrhizal inoculation increased root and shoot fresh weight, the dry weight of shoot; and the percentage of root infection on the onion. While the leaf litter of gamal increased only in leaf area. In contrast mycorrhizal inoculation and gamal leaf litter and their combination had no effect on other growth parameters. Key words: AMF, Glomus mosseae, Gliricidia sepium, Allium cepa.
