Abstract

This research aim to document traditional knowledge (indigenous knowledge) of the Hattam tribe in exploiting animals as traditional drug, in which the observation was done on the animal type, way of exploiting, and also on other culture and knowledge related to pattern of exploiting animals as drug in the life of the tribe. The result shows that there are 9 animals used as traditional drug in the life of the Hattam tribe in Mokwam village, that is: Rana grisea, Litoria arfakiana, Litoria micromembrana, Litoria angiana, Nyctimystes pulchra, Accipiter sp., Morelia viridis, Micropechis sp., and Sus sp.

Abstract

Several weed species were observed in the rice fields of the transmigration area Prafi SP 2 during April 2006 by the State University of Papua. The weeds were classified into three groups according to their morphology characteristics, and into four groups according to their habitat. The weeds were preferred by the rice pests as host plant. Few weeds were host for the rice fields such as Echinochloa crusgalli, Echinochloa glaberescens and Pennisetum purpureum.

Abstract

This study was done to study the diversity of butterflies and its distribution in the Gunung Meja National Park. A survey was carried out using transect count or line transect and the classification of Parson was used for habitat distribution. A number of 96 species of butterflies was encountered from the Family Papilionidae, Pieridae, Lycaenidae dan Nyphalidae. Three types of habitat covered the distribution of the butterflies’ species, i.e. primer forest with 41 species, secondary forest with 83 species, and garden and house yard with 49 species. Based on the t test, there is a significant differences on the diversity of each habitat (tcount > ttable; p > 0.05).

Abstract

The objective of this research was to know the structure, composition, potency of mangrove tree and also exploitation of mangrove observation type in Isenebuai Village District Rumberpon Teluk Wondama. Vegetation observation was conducted using line and plot method and the interview technique flourish structure. The result of analyse vegetasi study show that 11 mangrove plant species from 5 families were found.The 11 species are Aegiceras corniculatum, Bruguiera sylindrica, Bruguiera gymnorrhiza, Rhizophora stylosa ,Rhizophora mucronata, Ceriops tagal, Heritiera littoralis, Heritiera globosa, Lumnitzera litorea, Xylocarpus granatum and Xylocarpus moluccensis. The result also show that local people used 7 mangrove plant species from 4 families for 7 categories of use that are food-stuff, construction material, medicine, energy sources, boat supply, musical instrument and equipments of artistry and furniture.

Abstract

During about 19 days field work survey (7-25 February 2008) on the Haya lowland forest area, Mamberamo Papua. Eksploration is the methods used in this study. Reptiles and amphibians were collected by hand on the night and day in several type of habitat (plains, swamp, oxbowlake, stream, creeks and hills). The result showed that 48 species of herpetofauna (21 species frogs, 19 species of lizard, six species of snakes and one species of turtles and crocodile) were found.

Abstract

Kemudahan mengalami biodegradasi senyawa-senyawa polisiklik aromatik hidrokarbon (PAHs) dalam minyak mentah yang diekstrak dari tanah pada hari ke-0 dan ke-39 telah ditentukan. Sampel tanah yang digunakan dikontaminasikan dengan minyak mentah Barrow sebanyak 5% (w/w) untuk memperoleh sampel tanah yang sama dengan kondisi lingkungannya. Tingkat biodegradasi dari minyak mentah Barrow yang diekstrak dari sampel tanah pada hari ke 0 dan hari ke 39 ditentukan berdasarkan fraksi senyawa PAH yang dianalisis menggunakan GC-MS. Persen perubahan kelimpahan (abundances) terhadap waktu dari beberapa senyawa alkilnaptalena ditentukan untuk mengetahui urutan kemudahan terdegradasinya isomer senyawa-senyawa tersebut. Ditemukan bahwa isomer-isomer 2-metilnaptalena (2-MN) lebih mudah terdegradasi oleh mikrobiologi dibandingkan dengan isomer 1-MN. Analisis GC-MS terhadap sampel minyak mentah Barrow yang asli tidak menunjukkan adanya biodegradasi, namun ketika minyak mentah tersebut ditumpahkan ke tanah dan dibiarkan selama 39 hari pengamatan, minyak mentah tersebut mengalami biodegradasi ke tingkat 2-3.

Abstract

The waste material of agriculture such as the straw of rice was not yet used maximal as the kind of the materials for solution of environment pollution problem. Until this moment, there was any kind of ways that was done for separated the heavy metal from waste water, include the physical, chemistry and biology methods. Study of ion Pb2+ absorption using treated rice straw was carried out to determine the absorption of heavy metal from water. The result shows absorption of heavy Cr3+ > Pb2+ > Cu2+. The absorption interaction between Pb2+ ion and treated straw shows Langmuir pattern with maximum capacity of Pb2+ ions using the straw of rice was 52,083 mg Pb2+ /g the rice straw.

Abstract

Flavanoid, steroid, and terpenoid contents of 20 Manokwari medicinal plants were analyzed. The antioxidant activity, total phenolic contents and antitumor activity of 20 Manokwari medicinal plants were also evaluated. The result shows that 83% positif to flavanoid test, 59% positif to terpenoid test and only 25% positif steroid. Antioxidant activity and total phenolic contents evaluated using Ferric Thiocianate (FTC) and Folin-Ciocalteu methods respectively. Antioxidant activity and total phenolic contents of medicinal plants were extracted by the traditional method, boiling in water and also in 80% methanol. Twenty plants evaluated in both exstracts have significantly varies of antioxidant activities and phenolic contents, A significant and linier correlation coefficient between the antioxidant activity and the total phenolic content was found in both aqueous (R2= 0,77) and methanol (R2 = 0,85). Antitumor activity was tested using cell maurine P-388 and only 2 of medicinal plants are active to inhibit cell maurine P-388. Comparing extraction efficiency of the two methods, the methanol extracted phenolic compounds more efficiently, and antioxidant activity of the extract was higher
