Abstract

ABSTRACTSimilarity Level of Patchouli oil from Protoplast Fusion based on Morphology andAnatomy Leaves. Protoplast fusion between Aceh patchouli (Pogostenton cablin Benth)Tapak Tuan 75 clone and java patchouli (Pogostemon heyneanus Benth) Girilaya clone gonegenotypes variation. The aim of this experiment was to examine the similarities ofmorphology and anatomy of leaves. The experiment was inducted at laboratory and greenhouse of the Indonesian Spice and Medicinal Crops Research Institute from February to July2001. The parameters observed were the number of leaves length, leaves width and leafthickness, the number of oil cell, stomata and trachoma index. Analysis cluster was used toanalysis the data with single linkage method and Euclidean distance concept. The resultshowed that the leaves length, width, and thickness have close similarity with Tapak Tuan 75.The similarity level of genotype from protoplast fusion was 62.68 to 83.27, the parent TapakTuan 75 was 61.53 and the parent Girilaya 58.69. The highest numbers of oil cell was showedby clone 9 I1 4 (10.55) and the lowest was clone ( IV 14 (2.93).Key words: Pogostemon sp., similarity, protoplast fusion, morphology, anatomy, leaves.

Abstract

Hylarana nicobariensis (Stoliczka, 1870) is a very common frog, which has a wide distribution, covering the southern part of Thailand, Peninsular Malaysia, Sumatra, Borneo, Java, Bali and Palawan in the Philippines. The presence of this frog is very easy to be recognized by listening its shrill call that is sounded loudly all day. Detailed descriptions of H. nicobariensis’s calls from Ulu Gombak in Peninsular Malaysia and Danum Valley in Sarawak have been published by Jehle and Arak (1998), which are some call characters of the frog from the two locations are significantly different. To determine the call characters that can distinguish among populations of this frog, advertisement calls of five different populations (Batukaru, Curup, Limau Manis, Curug Nangka and Lake Ecology Park) were analyzed. The characters of the call waves on the five populations are different in the structure of sub-pulses, dominant frequency and lower frequency. Among the five populations, the population from Lake Ecology Park is the most different in the terms of the dominant frequency (3996.95 ± 124.74 Hz) and lower frequency (1692.51 ± 80.77 Hz), of this population both these characters occupy the highest level compared to four other populations; however individuals from Curup occupy the lowest level on dominant frequency (2919.67 ± 67.76 Hz) and lower frequency (832.96 ± 32.42 Hz).Key words: Ranidae, Hylarana nicobariensis, bioacoustics

Abstract

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

Abstract

ABSTRACTMetabolism of Benzonitriles by Flavobacterium sp. NUB 1. Flavobacterium sp. NUB 1 was isolated from industrial waste of PT. Petrokimia Gresik. The bacterium was able to utilize benzonitrile and acetonitrile and propionitril as the sole source of carbon and nitrogen. Growth on benzonitrile gave higher growth rate and biomass yield than growth on acetonitrile and propionitrile. When Flavovobacterium sp. NUB1 grew on benzonitril 15 mM , the doubling time is 9 hours 54 minutes and the specific growth rate (?) was 0,07 h-1. Whole cell of Flavobacterium sp. NUB 1 could hydrolyzed aromatic and aliphatic nitriles. The bacteria isolate has ability in metabolism of acetonitrile greater than benzonitrile. Activity of nitrile hydratase and amidase are more dominant than nitrilase in metabolism of benzonitrile.Key words: Biodegradation, benzonitril, Flavobacterium sp. NUB 1, nitrile-hydratase,amidase, nitrilase

Abstract

A phytosociological study has been conducted in the south-east slope of Mount Salak, Sukabumi, West Java.Vegetation data were analyzed using 21 plots made of 30 m x 30 m which covered various habitat conditions. Atotal of ninety seven tree species (dbh. ≥ 10 cm) were recorded belonging to 72 genera and 39 families. The mostdominant families occurred in the study area were Fagaceae, Hammamelidaceae and Euphorbiaceae, followed byTheaceae, Meliaceae and Sapindaceae. The dominance of those families was apparently from the contribution ofthe most dominant species Altingia excelsa and the other species such as the Schima wallichii, Castanopsis javanica,Pometia pinnata, and Lithocarpus korthalsii. Spatial distribution of the vegetation is affected by altitude and/orhabitat slope which develop forest community patterns, such as lowland forest, lower and upper slope forests, aswell as lower and upper mountain forests. The distribution of tree species also follows this pattern, i.e certainspecies only occur on certain (specific) habitat type.Keywords: species ekology, Gunung Halimun-Salak National Park, phytosociology

Abstract

Hubungan antra Perbedaan Tutupan Vegetasi Riparian pada Kondisi Air mengalir di kawasan Cikapinis, Jawa Barat. Vegetasi memiliki peran sangat penting di kawasan perairan yang mengalir; banyak hubungan antara tutupan vegetasi dengan aliran air dan struktur makroinvertebrata yang menghuninya. Oleh sebab itu penelitian dirancang di kawasan aliranCikapinis Jawa barat dengan mengambil contoh stasion penelitian yang terbagi menjadi tiga lokasi yaitu di hulu, tengah dan hilir. Kawasan tengah merupakan kawasan yang terbuka karena kebakaran 8 bulan sebelum penelitian. Kawasan hulu merupakan kawasan dengan kondisi banyak tertutup oleh tumbuhan perdu yang agak berbeda dengan kondisi kawasan hilir dan diikuti dengan kawasan tengah. Di kawasan tebangan, kandungan kimia air yaitu nitrat dan orthophosphat meningkat dan diikuti penurunan indeks diversitas makroinvertebrata, rendahnya kelimpahan teristimewa terjadi pada alga larva Petrophila sp. Analisis Komponen (PCA) yangdigunakan pada penelitian ini mengindikasikan adanya pengaruh antara vegetasi riparian dan kondisi fisik kimia air. Keeratan hubungan terlihat antara rendahnya tutupan vegetasi, tingginya suhu udara, intensitas sinar, kondisi tanah, nitrat, dan orthophosphat.Kata kunci: Vegetasi riparian, Aliran air, Kondisis fisik kimia, Makroinvertebrata, logging.

Abstract

ABSTRACTEcological aspect (morphometry, a complexity of community structure, trophic state, and carrying capacity) are one of basic information to build comprehensive management concept of aquatic ecosystem, as Lake Cilala.  The concept was addressed to develop ornamental fish floating cage and natural fishery activity.  Lake Cilala is a longwise shape small lake with maximum length, average width, and average depth as 1141 m, 161 m, 2.67 m respectively.  Lake Cilala has various genera of phytoplankton and zooplankton, 8 genera of benthos, 5 genera of aquatic plants, and 12 fish species including planktivore, herbivore, and carnivore fishes.  Those organisms established food chains, by grazing and detritus food chain.  The trophic state of Lake Cilala was categorized as middle to heavy eutrophic level by Trophic State Index (TSI).  The carrying capacity analysis of Lake Cilala is 130 tons/year. It is resulted a possibility to increase ornamental fish floating cage to 165 units from 300 existed units. Furthermore, the carrying capacity for natural fish was reached 3.77 tons/year. Keywords: carrying capacity, food chain, lake fisheries, small lake management, trophic state
