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

Sweet potato (Ipomoea batatas) is native plant comes from the American continent. It began to spread throughout the world, especially in the tropical countries in the 16th century. Papua Province is one of the regions with the largest area of harvested sweetpotato in Indonesia, therefore there is a high chance to develop food independence in Papua. Because of the Papuan people are accustomed consuming non-rice food. The study was conducted in the Biology Laboratory and the Pharmacy laboratory of MIPA Faculty Cenderawasih University and also the supporting Laboratory of The Papua Agricultural Research and Development Center (Balitbangtan). The purpose of  this research is to test the quality of flour of Keerom sweet potato varieties. Method for flour of sweet potato quality testing were using phytochemical screening  to determine the chemical compound group and using antioxidant test with the DPPH (1-diphenyl-2-picrylhydrazyl) method.  The results of the description of the Skanto District Keerom sweet potatoes in the field  were three (3) local varieties including Weayuken (purple sweet potato), Musanaken (yellow sweet potato) and Hiho (white sweet potato). The result of phytochemical  screening show that the purple sweet potato variety has more chemical compounds consist of tannins, quinones, flavonoids, terpenoids and alkaloids compared to white sweet potato consist of alkaloids only and yellow sweet potato consist of tannins, flavonoids, terpenoids and alkaloids. The result of antioxidant activity tests to flour extract ethanol  has IC50values of 299.82 ppm (purple sweet potato), 301.18 (yellow sweet potato), 1027.98 ppm (white sweet potato) respectively. So can be conclude that the purple sweet potato variety is the best. It was suggested for further research to isolate bioactive compounds and test antioxidants to other varieties in other centers areas of sweetpotato culture which have potential to develop for food, supplement and tradisional drugs.Key words: Sweet potato; local varieties; flour quality; phytochemical screening; antioxidant test

Abstract

Inventory study of cultivated orchid in District Merauke, Merauke City was done from March–June 2006.  Survey methods was used in this study. There were ten species of orchid in this area, consisted of 8 species of native Papuan orchids (Acriopsis javanica Reinw, Dendrobium anthenatum, Dendrobium diskolour Lind, Dendrobium konkolor Lind, Dendrobium nindii, Dendrobium johanes, and two hibrids), and 2 introduce species (Phalaenopsis sp and Phalaenopis amabilis). Dendrobium anthenatum, Dendrobium diskolour Lind, Dendrobium konkolor Lind, and Dendrobium johanes were the most frequently found species, Dendrobium johanes  were mostly encountered on the bark of eucalypt tree on secondary forest wich had high humidity. The problems in orchid cultivation in those area were drought, pest, pathogen, and lack of guidance in orchid cultivation as well. Key words: Inventory, orchid, Merauke District, Merauke City.

Abstract

Nyalik tribe community in Silimo District Yahukimo Regency Papua have traditional knowledge about the sweet potato (Ipomoea batatas (L.) Lam.) applied it in the cultivation.
