Abstract

Baturraden Botanical Garden is a complex ecosystem. Its natural resources, including several species of fern, provide an opportunity to be managed sustainably so it can be used to fulfill a long term of public need. This research was aimed to know the diversity of fern species and its potential as ornamental plants. The research was using survey method. The data was analyzed using descriptive comparative analysis. Species identification was performed by comparing the samples with herbarium specimens and also using identification keys. During the observation, 26 species of fern were found, which is consisted of 14 terrestrial species and 12 epiphyte species. Nephrolepis bisserata (Sw.) Schott. was terrestrial species with highest individual number and widest dispersion, whereas terrestrial species with smallest individual number and the narrowest distribution was Blechnum orientale Linn. Epiphytic fern species with highest individual number and widest dispersion was Nephrolepis falcata (Cap.) C. Chr., whereas epiphytic species with smallest individual number and narrowest distribution was Davallia triphylla Hk. From 26 fern species which were found at Baturraden Botanical Garden, 22 fern species were potential as ornamental plant which can be grew up either on land, pot or on host plant.

Abstract

The objective of this research was to study about species composition, distribution, and stock density of deep sea demersal fish in the southern Java of the Indian Ocean EEZ waters. This research was carried out based on data collected from the survey conducted between September and October 2004 using Baruna Jaya IV research vessel.  This study was basically conducted by applying swept area method with stratified random sampling.  The result showed that the species composition of deep sea demersal fish in southern of Java waters were consisted of 169 fishes, 31 crustaceans and 20 cephalopods and the catch of deep sea demersal fish was dominated by ashiro (Ophidiidae) about 45 % and hair tail (Trichiurus lepturus) about 22 %. The widest of species distribution of these resources in southern of Java waters was Chlorophtalmus nigromarginatus. The highest abundance of deep sea resources were caught on the depth of 700-1100 m and the lowest on the depth 200-400 m. Stock density of these resources in southern off Java waters was ranged from 794-39863 kg/km².

Abstract

Makassar strait is one of the important and strategic straits in Indonesia as it constitutes interislands and international sealanes. Its water condition is under the influence of both Kalimantan and Sulawesi islands, so that the dynamics in the region of marine and coastal environment becomes more complex. A study on water quality of bacteriological points of view in Makassar strait was conducted in October 2003. Seawater and sediment samples were collected by using the Research Vessel Baruna Jaya VIII at 16 stations. The aims of this study is to find out the water quality based on the contents of coliform bcteria and pathogenic bacteria Salmonella and Vibrio. The analysis of coliform bacteria was conducted by using membrane filter technique, while the pathogenic bacteria Salmonella and Vibrio were cultivated in the specific media Selenith broth and TCBS agar. The results showed that coliform bacteria at the surface layers depth varied from 80– 824 CFU/100mL with an average of 245 CFU/100mL, while those at the middle layer varied from 0–60 CFU/100mL with an average of 23 CFU/100mL. Seven pathogenic bacteria were isolated from seawater sample, i.e. Citrobacter spp., Edwardsiella spp., Proteus spp., Pseudomonas spp., Providencia spp., Shigella spp. and Vibrio spp, while eight pathogenic bacteria were obtained at sediment sample, i.e. Aeromonas spp., Citrobacter spp., Proteus spp., Pseudomonas spp., Providencia spp., Shigella spp., Yersenia spp. and Vibrio spp. These results indicated that coliform bacteria content in Makassar strait is under the threshold of Indonesian standard, i.e. Ministry Decree of Environment No: 51, 2004. Vibrio spp. was the pathogenic bacteria found both from seawater and sediment samples. In general, however, pathogenic bacteria was dominated by low pathogenic bacteria. Therefore, it can be concluded that from bacteriological point of view, water quality of Makassar strait is still relatively good.

Abstract

The transgenic rice of Cisadane and Rajalele cultivars (cv) was obtained by co-cultivation of rice callus by 4 strain Agrobacterium tumefaciens containing 4 different binary vector (pIG 121 Hm, pCAMBIA 1301, pTOK 233 and pMOG22 BarGus). The transgenic plantlets were acclimatized and grown in the growth chamber to investigate their agronomic characteristic in comparison to control plants. The results showed that there was no difference in the number of spikelet and seeds/spikelet among different transgenic lines co-cultivated by different strains. The number of seed/spikelet of transgenic rice cv. Rojolele and Cisadane compared to their control did not show significant difference. However, the total number of spikelet was different only for cv. Rojolele.

Abstract

Ethnobotany studies of wild banana species in Malinau, East Kalimantan has been done. There are two varieties of wild banana species in Malinau, e.g. Musa borneensis Becc. var. flavida Häkkinen & Meekiong and Musa acuminata Colla var. microcarpa Nasution. They have an important roles in the customs of the local communities in Malinau, Punan tribes as land certificate. In addition, young pseudostem of M. borneensis Becc. var. flavida often used as food in the traditional parties. The description and the uses of M. borneensis var. flavida and M. acuminata var. microcarpa are presented here.

Abstract

Diversity, distribution, and utilization of orchids have been studied on the mountains of Halimun-Salak National Park. Samples were taken from Citorek Resort with focused exploration on Citorek, Lebaktugu, Cinakem, Cibedug, and Ciawitali areas. The total,of 107 species belonging to 46 genera were recorded. As many as 27 species were recorded as javanese endemic species of Indonesian islands. Most species have no economic value and only a few orchids have been cultivated. The Calanthe, Cymbidium, Phaius and Renanthera have been used for cross breeding.
