The study aims at quantifying trade scale of some economically wild birds and describing captured trends which have been practised by wild bird catchers. The study was conducted in Tanah Grogot, Paser District, East Kalimantan Province, from September to December 2008, by surveying wild bird market and interviewing catchers and sellers. We measured two main attributes of market dynamics; first, each species availability in the market as the percentage of market days sampled where the species appeared; second, daily abundance of a species as the monthly average number of each bird per day for all days sampled. Seven wild bird species that have been traded commodities for years were White-rumped Shama Copsychus malabaricus (25.41%; 602.25+70.79 individuals per month), Yellow-vented Bulbul Pycnonotus goiavier (11.47%; 111.25+12.50 individuals per month), Crested Myna Acridotheres cristatellus (12.30%; 73.25+10.44 individuals per month), Spotted Dove Streptopelia chinensis (5.73%; 22.00+12.83 individuals per month), Hill Myna Gracula religiosa (12.30%;12.00+0.82 individuals per month), Greater Green Leafbird Chloropsis sonneratii (7.38%; 11.75+2.50 individuals per month) and Magpie Robin Copsychus saularis (6.56%; 8.75+1.71 individualsper month). Specific capture location within Paser District could reflect distribution and habitat preference of each bird species.

KONDISI VEGETASI DI KAWASAN HUTAN KEBUN RAYA BALIKPAPAN [Vegetation in the Forest at Balikpapan Botanical Garden] Hidayat, Syamsul
BERITA BIOLOGI Vol 12, No 3 (2013)
Publisher : Research Center for Biology-Indonesian Institute of Sciences

Balikpapan Botanical Gardens (East Kalimantan) is an ex situ conservation area where some parts of its land is originated from the Sungai Wain Protection Forest. Most of the area had been burned in 1982 and 1998. For the development of botanical gardens, vegetation condition/status assessment in forest areas is needed. The study was conducted by sampling with nested plot. Ten observations transects, each consisting of five plots measuring 20 m x 20 m set at ten locations which were supposed to represent the community. Results of the study showed that the quality of the vegetation in general was low, with medium category for conservation index and less category for diversity index. The vegetation was dominated by pioneer species that were less in conservation value such as Macaranga spp., Melicope glabra (Blume) T.G.Hartley and Calicarpa sp. There were 56 individual trees of nine species of Dipterocarp family -which is the regions native plants- found within this area. As for seedling stage, it was also dominated by pioneer species and shrubs. Species enrichment through the development of botanical garden, are expected to increase the value of biodiversity and conservation index.

A fertilization was set up in September 1993 in species-rich dipterocarp forest in the Barito Ulu study site in Central Kalimantan.The experiment was unusual in that previously reported fertilizer experiments have been made in montane forest. The following treatments were applied: control, +N, +P and +NP. There were five blocks of four 50m x 50m plots with a separate treatment for each plot. Fine litterfall was collected on all of the plots from May 1994 for one year. There was evidence of higher litterfall quantities and increased of P and N in the litterfall. All trees (> 10 cm dbh) were measured in August 1993 and in July 1994 and there was a clear girth increment response of some dipterocarp species to +NP and small size of trees to +N.

Â In principle, fish culture with aquaponics system save land utilization and can improve the efficiency of nutrient utilization of unconsumed feed and fish metabolism waste. Therefore, this system is recognized as environmentally friendly fish farming. The research aimed to find the optimum water retention for the maximum growth of tilapia raised in the aquaponics system. This experiment consisted of three treatments of different water retention, i.e. 30, 60, and 120 minutes and one flow- through recirculation system. Results showed that the highest individual weight gain of 39.92 g and individual daily growth rate of 0.54 g /day were reached in the treatment of 120 minutes water retention for 40 days growing period. Meanwhile, the lowest individual weight were observed in the treatment of 30 minutes water retention and control treatment, i.e. 25.25 Â± 1.22 g and 18.52 Â± 1.07 g, respectively. Aquaponic fish farming system with water retention of 120 minutes could reduced 10.69% of N- Total and 38.10% of P- Total, while survival rate was not influenced by water retention treatment

Water availability generally enhanced accumulation crop productivity in short time caused yield accumulation in that period. El-Nino, a climate phenomenon that increased of intensity and frequency lately caused planting period determination is being more important in minimizing agriculture risk like El-Nino. El-Nino impact on season displacement and rainfall drop were carried out with weighted regression between anomaly of rainfall and sea surface temperature (SST). Then, the information use to quantify rainfall fluctuation in relation with SST. Rainfall forecasting for next 3-6 month used in evaluation of planting period and then recommend some scenario with different level yield loss.Result showed that rainfall in north-side of East Kalimantan not affected by SST, but in south-side the correlation was significant. Especially El-Nino 1997 has forwarded dry season and delaied wet season.Analysis of planting period on dry season showed that paddy, corn, and tomato had high yield loss caused by water stress.Cropping pattern and planting period modification were required to suppress the yield loss. One alternative was by implementing runoff and rainfall harvesting to avoid yield accumulation only in wet season. Conventional cropping pattern that rely on rainfall should be managed in to whole area, so that quantity and continuity of yield may be able to be optimized.

A laboratory study in 2007 on seed physiology of gewang/talipot palm {Corypha utan Lamarck) - by splitting down the seeds by liquid nitrogen technique, revealed that not all seeds - only 20% - bearing mature embryos. Those embryos are highly protected by robust endocarp and endosperm. A further study was done to reconfirm the previous result, found that seed bearing embryo from 3 different ecotypes of gewang in East Nusa Tenggara (NTT) shows a relatively high diversity in seed bearing embryo originated from different ecotypes, ranging from 16 to 57%. Embryolessness seeds is assumed as due to the antagonistic interaction between GA, (gibberellic acid) and ABA (abscisic acid) during embryogenesis. Chemical content of seeds also shows relatively high in carbohaydrate and protein, while lipids were relatively low. Microbes identified as Fusarium and Bacillus was found in the surface of endocarp; Fusarium shows a more capability to decompose the endocarp of gewang seeds, thus allowed imbibition process, which lead to seed germination. Although Fusarium known as a soil borne disease for plants, their roles in endocarp/testa decomposition is important and needed by gewang to proceed seed germination. While the coming seedling of gewang may develop probably an internal resistance against Fusarium.

The base populations were composed to support selective breeding of giant freshwater prawn (Macrobrachium rosenbergii). Composite population were improved additive and dominance of genetic variance, especially for character of economic important. Economic character of giant freshwater prawn have a ratio of carapace length to standard length (ratio CL/SL).This research is aimed to improved the genetic of carapace and standard length ratio for giant freshwater prawn based on family selection. Selection methods were conducted on trait of carapace and standard length ratio as an edible portion. The base population prawn were used from three location i.e. Cimanuk (Cape of Air, West Java), Citanduy (Pamarican,West Java) and Musi River (Palembang, South Sumatra). Family selection was used selectedstructure. Parents were selected based on breeding value. Natural spawning was used product to first generation (F1) production of population. Larval rearing was used clear water system, fingerling production in the concrete tank, and juvenile rearing was conducted on earthen ponds. Respons selection was estimated to five months of freshwater prawn. Result of this experiment indicated that population of giant freshwater prawn can build by breeding program with heritability value of dressing out to 0.56+0.07; selection differential to 13.74 and selection intensity to 4.05. Prediction of genetic improvement from that genetic parameters is a value 7.69% to one generation. Implementation of population would be increased of genetic quality and there is decreased of gen degradation to prawn population.
