Abstract

ABSTRACTBioacumulation of Cadmium on Green Mussel (Perna viridis) Using Radiotracer. A laboratoryexperiment on the accumulation of Cadmium (Cd) by green mussel (Perna viridis) has beenconducted. Radiotracer 109Cd was applied in the study. The research aimed at evaluating theeffect of salinity, temperature and size on uptake of radiotracer 109Cd by green mussel (Pernaviridis) from dissolved phase. It was found that both salinity and temperature had significanteffect ( P< 0.001) on accumulation rate of 109Cd. The highest concentration factor of Cd (31,23-54,09) was appeared in water salinity of 29% and of water temperature 30oC. At the steady statecondition green mussel accumulated 72,21-107,80 Bq/gr Cd. It revealed that the small Pernaviridis (5.2 cm in length) accumulated 109Cd about 107,80 Bq/gr, whereas the bigger size ofPerna viridis (6.6 cm in length) had an uptake of about 72,21 Bq/gr.Key words : Bioaccumulation, radiotracer Cd, Perna viridisKata kunci : Bioakumulasi, Perunut radioaktif, Cd, Perna viridis

Abstract

ABSTRACTBacterial inoculants affect the early growth of Jatropha (Jatropha curcas L). Genera ofAzotobacter, Bacillus, Chromobacterium, Citrobacter, Nitrosomonas, Rhizobium, andSpaerotillus natans were soil bacterial isolates. The soil was collected from numerous placesaround Pontianak, West Kalimantan. Those isolates were used as inoculants, and formulatedto single and mixed bacterial inoculants, then used to stimulate the early growth of jatrophaseedling in 15 weeks at greenhouse condition. Bacterial inoculations caused better growthperformance compared to its control as pure soil garden medium without inoculations, andneither to bare soil dresses with compost. In the presence of inoculants, plant height wasaccelerated quickly while other inoculants affected to stalk diameter development. Daily growthperformance of jatropha peaked in 8 and 11 weeks after inoculation of Citrobacter andNitrosomonas bacterial component were used as single inoculant, respectively. The increasingof shoot biomass accumulation was three times as caused by single inoculants (Bacillus sp),and the highest one up to four times of biomass weight caused by a mixture inoculants asconsortium of Azotobacter, Bacillus, and Nitrosomonas spp. That selective inoculant hasopportunity to be used for jatropha farming, and this basic study is meaningful to jatropacultivation for standing to bio-fuel resources.Keywords: Jatropha curcas L., inoculants, Azotobacter, Bacillus, Chromobacterium,Citrobacter, Nitrosomonas, Rhizobium , Spaerotillus natans.Kata kunci: Jatropha curcas L., inoculants, Azotobacter, Bacillus, Chromobacterium,Citrobacter, Nitrosomonas, Rhizobium , Spaerotillus natans.

ABSTRAKJenis Idiosepius (Mollusca: Cephalopoda) di perairan Indonesia. Informasi dan penelitiantentang sotong mini “pygmy squid” marga Idiosepius yang ada di Indonesia sangat kurang,meskipun pernah dilaporkan setidaknya ada tiga jenis dijumpai di Ambon, Ternate, Banda,Balikpapan, Sibolga dan Lombok. Dalam tulisan ini diuraikan karakter morfologi, habitat dandistribusi empat jenis sotong mini jenis I. picteti, I. pygmaeus, I. biserialis dan I. pygmaeusherbereri. Karena ukurannya yang sangat kecil, jenis sotong ini tidak diminati oleh paranelayan, sehingga hanya sedikit data yang diketahui mengenai pertumbuhan, reproduksi dansiklus hidupnya. Penelitian ini bertujuan untuk memberikan gambaran ringkas tentangsistematik, habitat, siklus hidup dan distribusi Idiosepius. Hasil studi ini mencatat lokasi baru(new record) ditemukannya sotong mini jenis I. biserialis dan I. pygmaeus khusus dari perairanpantai di Lombok. Hasil penelitian juga menunjukkan bahwa beberapa jenis Idiosepiusmemiliki sebaran yang luas di perairan Indonesia kecuali jenis I. picteti hingga saat ini hanyadijumpai di Ambon. Hasil studi diharapakan menambah khasanah pengetahuan tentang sotongmungil ini sekaligus memacu para peneliti untuk lebih memperhatikan genus ini.Keywords: Cephalopoda, distribution, habitat, Idiosepiidae, Indo-PacificKata kunci: Cephalopoda, distribusi, habitat, Idiosepiidae, Indo-Pacific

ABSTRACTVegetation Analysis of Lowland Forest in Batanta Island, Raja Ampat, Papua. A vegetationanalysis of Batanta lowland forest has been made by setting up 17 plots of each 30-m x 30-mdistributed in 3 study sites were Yenanas (5 plots), Yensawai (7 plots) and Wailebet (5 plots).All trees (dbh. e”10 cm) within all of 17 plots were measured, and determined their positions,and identify their species. In total there were 171 tree species recorded within plots andbelonging to 108 genera and 40 families. Pometia pinnata was the most common speciesfollowed by Anthocephalus macrophyllus, Pangium edule, Toxotrophis illicifolius, andKoordersiodendron pinnatum. Almost all of common species such as Pometia pinnata,Anthocephalus macrophyllus, Celtis hidebrandii and Intsia bijuga were observed as theemergent and/or canopy trees. According to ordination analysis there were five communitytypes, Aporusa–Pometia, Antocephalus-Toxotrophis, Sterculia-Grewia, Ficus-Antocephalus,and Duabanga-Pterocymbium communities. However floristic compositions varied amongplot sites, which might be a characteristic of vegetation of Papua and the nearby small islands.Keywords: Vegetation, lowland forest, Raja Ampat, PapuaKata kunci: Vegetasi, hutan dataran rendah, Raja ampat, Papua
