Abstract

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.

Abstract

Dalam penentuan kesuburan suatu perairan, plankton mempunyai peranan penting. Hal ini disebabkan karena plankton merupakan produsen yang mampu melakukan fotosintesis. Plankton mempunyai peranan penting dalam sistem rantai makanan di kawasan perairan, baik di laut, perairan air tawar maupun payau. Sehubungan dengan hal tersebut telah dilakukan penelitian tentang keragaman jenis plankton di perairan laut di Kota Jayapura. Metode yang digunakan adalah survey, dengan pengambilan sampel pada tiga (3) lokasi yang berbeda, yakni di Pantai Dok II, Pantai Hamadi, dan Pantai Skow Mabo. Hasil penelitian menunjukkan bahwa di Kota Jayapura, khususnya di stasiun penelitian Pantai Dok II, Pantai Hamadi, dan Pantai Skow dijumpai 52 jenis plankton. Dari 52 jenis tersebut satu (1) diantaranya belum dapat teridentifikasi, yakni dari jenis fitoplankton. Di Pantai Dok II, dijumpai 25 jenis, pantai Hamadi terbanyak yakni 32 jenis, dan Pantai Skow hanya 16 jenis. Jenis–jenis plankton di lokasi ini menunjukkan tingkat kesuburan perairan pantai. Pantai Hamadi tergolong jenisnya sangat beragam, sedangkan pantai Skow tidak mempunyai keragaman yang tinggi.Key words: Keragaman plankton, Pantai Dok II, Pantai Hamadi, Pantai Skow, Jayapura.

Abstract

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.

Abstract

Alcohol (ethanol) has long been used as liquor. In some areas in Indonesia, the use of ethanol is an insaperable part of family rites and traditional festivities.  However, due to its serious consequences, alcoholism becomes a chronic social problem. Ethanol effects the metabolism in body organs and tissues, including male reproductive organ. The objective of this study was to prove that ethanol comsumption may reduce the weight of testis. This study used Posttest Only Group Design with experimental animals of 30 male rats (Wistar strain Rattus norvegicus) that were subjected in five types of treatment, i.e,(1) feeding with aquades 2ml/day as control group (2) feeding with 10% 1 gr/Kg/day of ethanol, (3) feeding with 10% 3gr/Kg/day of ethanol, (4) feeding with 30% 1 gr/Kg/day of ethanol and (5) feeding with 30% 3 gr/Kg/day of ethanol. Treatment was given daily for 45 days. At the end of the study, on the day 46th, the rats was sacrified for examination. Sample of testis were taken for weight examination.  Data were analysed using Anova and when the difference was found, the analysis was followed with Least significant Difference at the level of significance of 95%. The result of this study showed that ethanol reduced the weight of testis compared to control. The results of Anova  test revealed that higher dosage and concentrations of ethanol resulted in significantly different decrease of the testis’s weight (p<0,05) compared to other dosage and other concetration. In conclusion, ethanol has effect in the reduction of the weight of the testis.Key words: ethanol, male reproduction, Rattus norvegicus, weight of testis.

Abstract

Protein merupakan salah satu makronutrien penting bagi tubuh. Fungsinya sebagai zat pembangun dan memelihara sel-sel dan jaringan tubuh, menyebabkan kekurangan protein akan berakibat serius bagi kesehatan. Salah satu alternatif pemenuhan kebutuhan protein adalah dengan pemanfaatan bahan pangan lokal. Ulat sagu (Rhynchophorus papuanus) telah lama dikonsumsi oleh masyarakat asli Papua dan Maluku sebagai pelengkap (lauk) bubur sagu (papeda) dan diketahui dari kandungan zat gizinya dapat berperan sebagai sumber protein. Penelitian ini bertujuan mengetahui kualitas protein ulat sagu (Rhynchophorus papuanus). Ulat sagu dikembangbiakkan pada media batang sagu dengan tiga varietas sagu masing-masing adalah Debet Embyam, Kutu blup, dan Kutu Mamakutu (berdasarkan pengetahuan indigineus etnik Moy). Dilakukan analisis kimiawi untuk mengetahui kadar protein, lemak, air, dan abu. Sedangkan kualitas protein ulat sagu ditentukan dengan penentuan NPR (net protein ratio) dan penentuan nilai kimia asam amino. Hasil penelitian menunjukkan bahwa ulat sagu mengadung protein dengan kualitas cukup baik, yang diperlihatkan dengan nilai kimia asam amino ulat sagu, masing-masing yang dikembangbiakkan pada Debet Embyam = 97,54%; Kutu blup = 80,77%; dan Kutu Mamakutu = 77,53% dengan asam amino pembatas metionin. Sedangkan nilai NPRnya masing-masing 3,31; 3,16; dan 3,17. Tidak ada perbedaan yang signifikan terhadap nilai NPR ketiga perlakuan tersebut.Key words: Kualitas protein, ulat sagu, Maribu, Jayapura.
