Abstract

Estuary basin is a fertile area which has important role for sustaining many organisms from estuary and sea. Mould andother saprobic microorganisms have important role to decomposing organic material in estuary water. A study on diversity and abundance of mould inhabiting Muara Layang estuary sediment, Bangka Belitung Islands has not been conducted before. The objective of this study is to investigate the abundance and diversity of mould inhabiting Muara Layang estuary sediment, Bangka Belitung Islands. The mould isolation was based on sample dilution method with Rose BengalChloramphenicol Agar mould isolation media. The abundance of mould was counted by measuring the average Colony Forming Unit (CFU)/ml of all mould colonies which grown on isolation media by Total Plate Count (TPC) method. The diversity of isolated mould was identified based on phenotypic characters by observing both of macroscopic and microscopic mould morphology. The result showed that the growth average of mould colonies is about (5-27.5) x102 CFU/mL. The result of mould identification showed that eight mould genera, Aspergillus (6 species), Chaetomium, Eupenicillium (3 species), Gliocladium, Paecilomyces, Penicillium (3 species), Scopulariopsis, Trichoderma (3 species), one group identified in class level (Coelomycetes), and three groups of unidentified sterile mould isolates were isolated.Key words: estuary, mould, sediment, abundance, diversity.

Abstract

The character of social interactions and grouping patterns of Sumatran orangutans (Pongo abelii) have been studied in Ketambe research station of the Gunung Leuser National Park, Sumatra. A total number of 141 groupings and 47 incidences of interactive behavior were observed during the course of study. The character of groups (feeding group or travel-band) and the type of food trees (fig tree or fruit tree) appear to influence the interactive behavior of individual orangutans. Intolerance behavior has been characterized by feeding group in large fig trees, whereas tolerance and sexual behavior were shown mostly in travel-band.Key words: feeding group, travel-band, social interaction, Sumatran orangutan, Pongo abelii.

Abstract

The incident of hyperhydricity was a common problem in propagated carnation (Dianthus caryophyllus L.) during in vitroculture. Due to its possible relations with the decrease in phenotypic performance of plantlets, the observation on theoccurrence of hyperhydricity was conducted on several in vitro conserved carnation cultivars. The research was conductedfrom July 2007 to August 2008 at The Indonesian Ornamental Crops Research Institute, Cianjur, West Java. A completefactorial experiment with 24 replications was designed to accomplish the combination of two factors. The first factor was six commercial carnation cultivars, namely light pink candy, malaga, opera, white candy, liberty and pink maladi, while theseconds dealt with type of conservation media, i.e. ½MS+DMSO 3%, ½MS+DMSO 3%+3% sucrose and control (½MS+3% sucrose). The results showed that the percentage of hyperhydric plantlet and plantlet viability after in vitro conservation were varied among carnation cultivars. Single treatment of sucrose had the least capacity in inducing plantlet resistance to low temperature conditions during in vitro conservation. Supplemental DMSO postponed the occurrence of hyperhydricityand with the existence of sucrose, higher plantlet viability were achieved.Key words: carnation (Dianthus caryophyllus L.), cultivar, hyperhydricity, plantlet viability, in vitro conservation.

Abstract

Biodiversity of black coral (order Antipatharia) collected from the Bunaken Marine Park (Manado Sea, Indonesia) has been studied based on the sequence of the Internal Transcribed Spacers (ITS) region of rDNA gene. The results of the study showed that the 18 species of Antipatharia were considered to be separated in two family groups, family Myriopathidae and Antipathidae-Aphanipathida. A significant species-specific signal has been detected among the families of Antipathidae andAphanipathida. However, more studies-on different species were required to be clearly interpreted. The new species Pseudocirrhipathes mapia, the new genus Reticulopathes, and possibly a new taxon of the family Myriopathidae has beenrecognized based on ITS sequence data.Key words: biodiversity study, Manado, rDNA ITS, Antipatharia, black coral.

Abstract

This research aim to study how Benuaq society around Muara Lawa District, manage agriculture system and internal knowledge about rice varieties. This research use ethnobotanical approach: collecting ethnobotanical data of rice varieties and traditional system of swidden cultivation. Data was obtained by using direct participatory technique by interviewing the people (key informants) about their practice and perception. The interviews were unstructured open-ended discussion onknowledge and farming activities including about diversity in rice varieties. Subsequently, quantitative data from questionnaires was combined with depth-interview data from key informants. The Benuaq indigenous systems, practices, and cultivation preferences held by the Benuaq are guarded toward maintaining their rice diversity. The Benuaq systems of upland rice cultivation, site selection for umaq establishment, plant species for fertility indicator, and cultivation of wide ranges of upland rice varieties indicate their sophisticate knowledge in agriculture. Unfortunately there has been degradation in the indigenous knowledge among the young Benuaqs.Key words: Benuaq, ethnobotanical, indigenous, upland rice.

Abstract

Investigation on diversity of stomata from 13 species of family Euphorbiaceae has been carried out. Characters like type of stomata, position of stomata, presence/absence of ledge, and density both abaxial and adaxial leaf surface were examined.Stomata characters in the family were found quite diverse in this study. Monophyletic nature of Euphorbiaceae has been proved in this study on the basis of phylogenetic analysis using parsimoni method. Our data further suggested that the family can be classified into two major groups. However, surprisingly, genus Phyllanthus is non-monophyletic.Key words: diversity, Euphorbiaceae, phylogenetic analysis, stomata.

Abstract

Dyera costulata (Miq.) Hook.f (Apocynaceae) is a large tree of the lowland tropical rain forest of Southeast Asia, Thailand, Malay Peninsula and Indonesia, especially in Sumatra and Kalimantan (Borneo) islands. Its economic value was in its copious latex, used as gum in the manufacture of chewing gum. Today the timber of this species is much sought after for the manufacture of pencils and picture frames. Information on genetic diversity of the species is very limited. Hence studieswere initiated to screen primers for RAPD analyses of Dyera costulata for use in genetic variation studies. Seventy one Operon primers (10 mer) were used to generate a total of 864 consistent and ambiguous amplification products ranging from 200 bp to 2.0 kb. Rare and genotype specific bands were identified which could be effectively used to distinguish the genotypes. 34 highly polymorphic primers (100%) are recorded from 71 primers used. Three primers (OPA-04, OPU-06, and OPU-07) produced highest variable RAPD profiles. The dendrogram separated the 8 genotypes into 2 groups. Geneticdissimilarity ranged from 0.07 to 0.71 %.Key words: Dyera costulata, jelutong, primer screening, RAPD.

Abstract

The objectives of this study were to provide reliable data and information on reef fish in the northern Aceh region of Wehand Aceh islands based on management types. This research use underwater visual census techniques at 29 sites aroundWeh Island and Aceh Islands. Reef fish abundance in area that were protected under the management of Panglima Laot ofSabang Weh Island (32505 no.ha-1) and biomass (748 kg.ha-1) were also significantly higher than in Aceh Islands which is open access areas (abundance=9539 no.ha-1; biomass=396 kg.ha-1). Fish species from the family Pomacentridae (damsel fish) were highest in abundance and biomass at northern Acehnese reef. Population of carnivorous fish such as parrotfish (Family Scaridae) was low in all study sites which indicated that northern Acehnese reef is lack of reef resilience both in managed and open access area. Higher numbers and abundance of reef fish in marine managed areas, such as Panglima Laot in Sabang, could be considered for further conservation purpose of marine resources.Key words: Coral reef, reef fish, management type, northern Acehnese reef

Abstract

Fourteen genotypes of Indonesia cassava (Manihot esculenta Crantz) of two generations were evaluated for β-carotene content. The β-carotene content of tubers and leaves were determined by spectrophotometry method. Other parameterssuch as water and ash contents were also evaluated. Results showed that β-carotene content of tubers of fourth generation(planted in 2006-2007) was higher than that of first generation (planted in 2002-2003), with the exception of Apuy, Iding andSarewen genotypes. β-carotene content of tubers was lower than that in their leaves of fourth generation plants and that there was no correlation between both organs in terms of β-carotene content of tubers and their leaves except for Tim-Tim 40 genotype. β-carotene content of tubers in several genotypes i.e. Kalbar III (1.13 ppm), Local Muneng (1.03 ppm), Tim-Tim 29 (1.61 ppm) was higher than 1 ppm, and the highest value was found in Tim-Tim 40 (16.83 ppm) which was significantly different (5%) with other genotypes. Meanwhile the lowest content was found in Sarewen genotype as it could not be detected. Water and ash contents of the tubers were between 54 and 69% and between 0.20 and 0.79% respectively. As β-carotene is the precursor of vitamin A, consuming high β-carotene tubers are sufficient for daily requirements of vitamin A, although further study is needed.Key words: cassava, Manihot esculenta, genotype, selection, β-carotene, tubers, leaves

Abstract

Seedling is the first and prominent phase of plant development. Seedling performance can be determined by seed and itsembedded characteristics, among them is seed weight. In this study we would like to see how seed weight within species affect seedling establishment. The hypotheses tested were that heavier seed is regarded advantageous compared to lighterseed by functionally produce more competitive seedlings for better growth. Heavier seeds indeed resulted in higher shootlength than lighter seeds. The same pattern was also pronounced for the correlation between seed weight and shoot length of Syzygium bankense and Quercus gemelliflora. There was also a significant positive correlation between seed size andnumber of leaf within species.Key words: seed weight, Syzygium bankense, Quercus gemelliflora, seedling establishment, germination
