<![CDATA[A study on the exploration of bird diversity in Gunung Ambang Nature Reserve was performed to collect much information on the existence of the bird species especially the endemic bird species in Wallace bioregion. This research was done by using two methods, an irregular transect method and a method with mistnet installation to determine the bird morphological characteristics. The observation area was determined purposively. A total of68 species has been recorded from this research and those were dominated by family Columbidae. From the total species found, it could be classified into 32 families and 28 species including the endemic bird species. Seven bird species have been obtained from the mistnet method and among them, four species were found as endemic species. They were Dark-eared Myza (Myza celebensis celebensis), Matinan Blue Flycatcher (Cyornis sanfordi), Speckled Boobook (Ninox punctulata), and Sulawesi Leaf-warbler (Phylloscopus sarasinorum nesophilus).]]>

<![CDATA[Golden cyst nematode (GCN/Globodera rostochiensis) is a new potato parasitic nematodes found in Indonesia in 2003 and caused great economic losses more than 70% of the production. Due to the problem caused by chemically control (resistancy, killed non target organisms, and environment pollution) development of alternative control measures is a great importance i.g. microbial control. The purpose of this research was to find chitinolytic and proteolytic actinomycetes for controling eggshell nematode which bears vitelin (protein) and chitin. The result found 21 actinomycetes isolates with ratio chitinolytic and proteolytic activities more than 3.0 and among of seven isolates were chitinolytic, 11 isolates were proteolytic and three isolates had double enzyme activities. Seven selected isolates were examined on their chitinase and protease specific activities and ability to degrade nematode eggs. The results showed three isolates had chitinase activity more than 200 IU/mg, four isolates had protease activity more than 300 IU/mg. Results of the bioassay test using crude enzyme on the GCN eggs found that three isolates were able to damage eggs more than 90%. The three isolates can be applied as an agent for biocontrol of GCN in the future.]]>

<![CDATA[Soybean curd whey, which is discarded as a waste, can be used as starting material for the preparation of cellulose and cellulose acetate membrane. However, due to its poor mechanical properties, blending with polystyrene will strengthen to the membrane. Nata de soya was made by soybean curd whey then was dried to produce cellulose flake. Cellulose flake was reacted with acetylation reagent, acetic anhydride, and other solvents to produce cellulose acetat flake. It was then mixed with polystyrene to form blend of cellulose acetate:polysyrene membrane with 100:0, 95:5, 90:10, 85:15, and 80:20 in ratios. These membranes were characterized by water flux, rejection index, and tensile strength. The results showed that cellulose acetate had produced a water content of 4.3%, and acetyl degree of 43.26% (equal to substitution degree of 2.8-3.0). The highest water flux membrane was made of 80:20 (164.23 l/m2., the highest rejection index was from 90:10 was 31.65%, and the highest tensile strength membrane was obtained from 80:20 (24.11 kgf). In conclusion the addition of polystyrene could increase the water flux and tensile strength of membrane, but it decrease the rejection index.]]>

<![CDATA[This paper studied three methods of pan-sharpenning of SPOT-4 image and evaluated the quality of the results. Three pan-sharpenning methods were applied to a scene of SPOT-4 image of K/J:287/364 acquiried on 25 July 2008 by using image processing software. Those three methods were IHS-RGB, Color Normalized (Brovey), and PCA (Principle Component Analysis). For IHS-RGB and Color Normalized (Brovey) methods the formulas written in Kartasasmita were used. These formula are practical to be used in image processing software and canbe understood theoritically. Similarly for PCA (Principle Component Analysis) method on this research the values of the elements of eigenvectors, which are required for doing the transformation and inversion, are calculated before then they are used in a new more practical equation and can be inputted to image processing software. It was expected that three mathematic equations from those three methods can be implemented easily in other image processing softwares and used for other multispectral image sharpenning by panchromatic band. An assessment to test the pan-sharpenning processes quantitatively and qualitatively were conducted. A qualitative assessment had been conducted by visual interpretation of pansharpened image. Quantitative assessments of pan-sharpened image was showed by change of spectral value range of each spectral channel, measureof the slope detail of pansharpened image from several object detail and the spectral information similarity between original and pansharpened images by Q Index and Correlation Coefficient. The results of this study are practical equations for PCA, IHS-RGB and Color Normalized (Brovey) Methods; pan-sharpened of SPOT-4 image; and quality assessment of pan-sharpened of SPOT-4 image.]]>

<![CDATA[Designing of future approaches for the control of Fasciola gigantica infection in cattle requires an understanding of the host-parasite relationships. This study was therefore undertaken to compare the susceptibility to infection with F. gigantica between Bali and Madura cattle. Seven Bali and seven Madura cattle were infected orally with 15 metacercariae of F. gigantica twice weekly for 32 weeks. Similar observations were made on four Bali and 4 Madura cattle maintained fluke-free as controls. The study shows that there was a trend of a lower fluke burden and faecal egg counts Madura cattle than in Bali cattle. The packed cell volume (PCV) values was significantlyhigher in infected Madura than in Bali cattle (P<0,05). The increased of eosinophil cell response and the antibody isotypes imunoglobulin (Ig)G1 in Madura cattle were significantly higher than in Bali cattle (P<0,05). These varying responses represent differences in host-parasite relationships between Bali and Madura cattle and may be linked to the observed varying levels of resistance to F. gigantica infection between these host.]]>

<![CDATA[Organic electrocoating process is the plating process using organic material to be plate on the conductor materials. The process is almost the same with other electroplating process, but they have several benefits such asno hazardous content, the plating sequence more shorter than electroplating process, and is possible to depositeng clear or tinted polyurethane plating. The organic electrocoating steps consist of surface treatment which is immersing the sample to the alkaline soak cleaner solution than acid mild dipping, continue to deionised rinse, organicelectrocoating, deionised rinse, post dye, and curing. The result of the experiment shows that the optimal Organic electrocoating process is held at voltage 35–40 V to give the best surface layer.]]>

<![CDATA[Ciwalen River flows pass of leather industry in Sukaregang area that is the one of the prominent industry in Garut region. The usage of chemicals in the leather tanning process resulted in toxic liquid waste released to Ciwalen River. Ciwalen River containing contaminants would further contaminate the groundwater system along the Ciwalen River. The study of groundwater flow particularly hydrodynamic relation river and groundwater surrounding is required. Field and secondary data were utilized in this study. Groundwater flow and hydrodynamic relation river and groundwater analyses were carried out using Visual Modflow v3.1. software. The study results that hydrodynamic relationship between Ciwalen River and the groundwater system can be divided into 6 segments. Segment 1, 4, and 6 belong to effluent type, while segment 2 is of influent type. Segment 3 and 5 located right of the river are effluent and those located in the left of the river are of influent type. River channel length of segment 1 are 0.95 km, length of segment 2 are 0.62 km, length of segment 3 are 0.88 km, length of segment 4 are 0.21 km, length of segment 5 are 0.63 km and length of segment 6 are 1.18 km. Influent type indicate causes a groundwater pollution because river that’s containing contaminants would further contaminate the roundwater system particularly at urban wells in surrounding segment.]]>
