Abstract

H. SIMBOLON 1988.Soil nutrients loss on a slope in the primary forest of Dumoga-Bone Nationat Park.North Sulawesi. Berita Biologi 3(8): 413 -417.The lost of soil nutriens in the lowland primary forest have beer studied in Lombongo,Dumoga-Bone National Park (North Sulawesi).The forest was dominated by Pometia pinnata with 25.71% of relative basal area.The forest canopy was built up by 368 trees per ha and the soil surface was covered by 353.92 g per m of litterfall (mean of fresh weight).The soil-and litterfall nutrient status of the study plots was less than that of the other primary tropical rain forests.Even though the soils were fully covered by litterfall, the erosion and leaching processes were still occurring.The leaching rate of the soil nutrients was 3.26% on C(the lowest rate) and 14.46% on P2Q5 (the highest rate),but no significant decrease on N was observed.

Abstract

Pada dasarnya tipe mulut serangga dibagi menjadi 2 golongan besar yaitu tipe pengunyah dan tipe pengisap (Boiror & De Long 1954).Mulut bertipe pengunyah ditandai dengan mandibula kuat yang dapat digerakkan ke samping. Mulut bertipe pengisap telah mengalami variasi dan modifikasi sehingga berbentuk pipa pengisap.Salah satu kelompok besar serangga yang sangat beranekaragam ialah kumbang atau Coleoptera.Walaupun beranekaragam, semua Coleoptera mempunyai bagian mulut yang berfungsi sebagai pengunyah.Berdasarkan perbedaan makanannya, bentuk terperinci bagian-bagian mulut dan saluran pencernaan pemakan tumbuhan berbeda dari pemakan binatang.Perincian perbedaan pada Coleoptera masih belum banyak diungkapkan.Untuk menambah data umum yang telah diperoleh (Snodgrass1935,' Borror & De Long 1954, Imms 1957,Metcalf & Flint 1962),dilakukan pengamatan morfologi terhadap beberapa jenis Coleoptera pemakan kayu lapuk.

Abstract

Trypanosoma evansi, one of about 200 trypanosomes species encountered in mammals in the world, is the causative agent of an economically important disease among domestic animals called surra. Many studies on T. evansi has been made using various experimental animals such as chicks and fowls for kifectivity (Alwar 1962, Manuel & Cajita 1967), mice for influences of temperature (Marthur 1976) and rats for immunological studies (Assoku 1975). Even larger animals such as goats, pigs, horses, cattle and buffaloes have been used by several workers in studying T. evansi infections (Chand & Singh 1971, Gill 1971, Srivastava & Ahluwalia 1972).The present paper deals with the susceptibilities of small laboratory animals to T. evansi infections in order to determine which animals are suitable for maintaining T. Svansi in the laboratory. All works in this study were done at the Filariasis Research Division of the Institute for Medical Research (IMR), Kuala Lumpur.

Abstract

Sejak semula Kebun Raya Bogor - LBN selalu aktif mendatangkan dan tnemperkenalkan jenis-jenis tanaman baru, baik dari luar negeri maupun dari hutan belantara Indonesia sendiri.Kegiatan ini telah mempengaruhi keanekaragaman jenis tanaman yang dipakai penduduk kota madya Bogor dalam menghias halaman dan pekarangan rumahnya,karena mereka mendapat kesempatan pertama untuk mencobakan hasil jerih payah Kebun Raya Bogor itu. Selain itu baik keadaan flsik maupun iklim kota Bogor (ketinggian 190 - 280 m dpi.,rata-rata suhu bulanan 24-26°C, kelembaban udara 76 - 86%,penyinaran matahari 62%,kecepatan angin 1.3 m/detik,curah hujan 4122 mm/ tahun) sangatlah ideal untuk pertumbuhan tanaman.Karenanya tidaklah mengherankan jika lebih dari 625 jenis tanaman telah,dipakai oleh warga kota Bogor sebagai tanaman hias (Widiawati & Rifai 1975).Ini menunjukkan suatu jumlah yang besar mengingat bahwa Bruggeman (1948) hanya mencatat lebih kurang 750 jenis tanaman hias untuk seluruh Indonesia.

Abstract

SRI HARTINI. 1985. The infestation pattern of arthropod parasites on rat at Purwodadi Botanical Garden. East Java. Berita Biologi 3(3) : 108-110. An investigation to find out the pattern of infestation of arthropod parasites on Rattus tiomanicus and Rattus rattus diardi was conducted in Purwodadi Botanical Garden, East Java. The parasites studied were Laelaps nutalli, Echinolaelaps echidninus (Acarina), Hoplopleura pacifica, Polyplax spinulosa (Anoplura) and Xenopsylla cheopis (Siphonaptera). It was concluded that parasite prevalence depends on habitat, age and sex of the host.The number of parasite infesting R. tiomanicus is greater than that of R.r. diardi, Adult rats have a higher prevalence rate than juveniles; likewise female adult rats are also higher than other sex and age group.

Abstract

The in vitro study of antibacterial effectiveness of Rosella (Hibiscus sabdariffa L.) sheath ethanol extract and water extract on Streptococcus pneumoniae was conducted by diffusion and dilution method. Basic solution amounting to 70g/100 ml of the extract was diluted into 10%, 30%, 50% and 70% for diffusion test with positive control ampicillin 10 IU, and 0,1%, 0,25%, 0,5%, 1%, and 2% ethanol extract for dilution test on S. pneumoniae. The results showed that the ethanol extract and water extract could delay of bacterium growth. Agar diffusion test (disk diffusion) was observed by diameter of bar region around the disk. At concentration 70 % among extract ethanol and water extract made bar zone wide the best, the diameter mean was estimated 25.6 mm for ethanol extract, and 24.3 mm for water extract on S. pneumoniae. In dilution test, the result showed Minimum Inhibitory Concentration (MIC) of the extract was 1% on S. pneumoniae. The result of phytochemicals test is known that ethanol extract and water extract of rosella contains of saponin, tanin, and flavonoid.

Abstract

Caryota no Becc,(fish-tailpalm) is considered vulnerable palm, Its population is declining from the habitat by destructive exploitation but also to some extent by local people who remove the edible apex or 'cabbage 'as a vegetable and also obtain sago from the pith of the trunk,so kill the tree.A though its biological characteristics have not been fully studied,this species is also potentially for ornamental plant Thus conservation measures should be taken to improve the status of this threatened species. Tissue culture techniques may provide ways either to propagate or to conserve itin-vitro. Naturally Caryota no Becc.palm fruit after 20years and they can germinate more than 3 months after sowing with low germination value.In this experiment,the tissue culture response of this species are studied using the explant of embryo from (relatively) young fruit (juvenility fruit).The effect ofBA and 2,4D on the shoot growth, root growth and calluses was evaluated, while the evaluation of the effect ofactifated charcoal was discussed. The satisfactory results have not been achieved.
