<![CDATA[The role of arbuscular mycorrhizal fungi is very important in a coastal area with sandy soil, high salinity level and low available of phosphate. However, the salinity levels also affect the diversity and activities of mycorrhizal fungi. This research was aimed to learn about arbuscular mycorrhizal fungi in coastal forest based on the salinity gradients. The results demonstrated that spore density and percentage of mycorrhizal colonization decreased by increasing the soil salinity. The same effect was also showed on the observed spore types. Glomus was found as the dominant spore in the research area.]]>

<![CDATA[Three multimode-fiber couplers with different coupling ratios, excess losses and directivities are used to sense adisplacement. The fiber coupler is handmade from 1 mm diameter plastic optical fiber. The light source is 632.8nm He-Ne Laser. OPT 101 (Burr Brown) detector is used to detect the change in power output due to theobject’s displacement. The opted displacement’s resolution is 5 μm. The experiment shows that multimode-ficecoupler with 0.25 ratio, 1.37 dB excess loss, and 25 dB directivity gives the highest performance, which has 4mm dynamic range, 1 mm linear range, and 55.4 μW/mm sensitivity. Higher performance can be reached ifmultimode-fiber coupler with the highest coupling ratio and the lowest excess loss is opted.]]>

<![CDATA[There is adipocytokine dysregulation on obesity such as amplified leptin, and reduced adiponectin at serum levels . Leptin has been proved to increase oxidative stress in endothelial cell. The adipocyte functions as an important secretory organ via nuclear factor-κ B (NF-κB) releasing a number of bioactive molecules such as leptin. Lycopene, an antioxidant, is presumed having the ability to block the atherogenesis mechanism, which is stimulated a proinflamatory cytokine and adhesion molecules ICAM-1 by NF-κB. Therefore, the aim of this research was to prove and to determine whether lycopene could decrease the NF-κBandICAM-1 expressionin Human Umbillical Vein Endothelial Cells (HUVECs) culture induced by 500 ng/mL leptin. In vitro study used primary culture of the HUVECs were devided in to 7 groups, there were (1) 0 ng/mL leptin and 0 μM lycopene, (2) induced by 500 ng/mL leptin for 12 hours, (3) induced by leptin and lycopene with concentration 10; 25; 40; 55 and 75 μM for 12 hours. Then the identification of NF-κB was applied by using imunocytochemistry compared with ELISA procedure on cell endothel culture lysate and ICAM-1 expression was measured by using RT PCR. It was showed that lycopene 25 μM decreased NF-κB level and ICAM-1 expression significantly in Human Umbillical Vein Endothelial Cells (HUVECs) culture induced by leptin 500 ng/mL.Leptin was increased NF-κB and ICAM-1 expression in HUVECs culture and was decreased by lycopene. Optimum dose of lycopene is 25 μM.]]>

<![CDATA[Moustached thryssa is one of an important fishery commodity in ujung pangkah waters. The study aimed toinvestigate food habits of the fish caught in the area. This study was conducted in ujung pangkah waters, gresik,east java using fish samples (n=76 males, n=119 females) collected during january to june 2006. Research resultshows that shrimps was a main food, bivalva and parts of crustacean were complementary food, while copepodsand pollychaeta were suplementary food both for male and female fish. Based on index of stomach contents, theindex was higher during january and april for male and female fish. Percentage of food of the fish variedaccording to size. According to simmilariy index, the main food of male and female fish was simmilar. ]]>

<![CDATA[AMMI(Additive Main Effect Multiplicative Interaction)model for interactions in two-way table provide the major mean for studying stability and adaptability through genotype × environment interaction (GEI), which modeled by full interaction model. Eligibility of AMMI (Additive Main Effect Multiplicative Interaction) model depends on that assumption of normally independent distributed error with a constant variance. In the study of genotypes’ resistance, disease and pest (insect) incidence on a plant for example, the appropriateness of AMMI model is being doubtful. We can handle it by introducing multiplicative terms for interaction in wider class of modeling, Generalized Linear Models. Its called Generalized AMMI model. An algorithm of iterative alternating generalized regression of row and column estimates its parameters. GAMMI log-link model will be applied to the Poisson data distribution. GAMMI log-link models give us good information of the interaction by its log-odd ratio. ]]>

<![CDATA[In the classical finance theory, the CAPM models are developed using the Gaussian framework, that is, weassume the vector of returns can be modeled using the multivariate normal distribution. However, it is foundempirically that typically the financial data, especially the returns of assets, are leptokurtic (i.e., it is heavy tail andpeaked around the center). It has been shown in the literature that the stable distribution, where the normal is of aspecial case, becoming one of the popular model to model leptokurtic data. In this paper, we analyse the CAPMunder the assumption that the data follows the stable non-normal distribution with the index ofstability1 <α < 2 . We finally provide empirical application of the CAPM under the Gaussian and stable casesusing several returns data from Indonesian Stock Market.]]>

<![CDATA[Kalanchoe is the biggest genera of Crassulaceae family and distributed in tropical and subtropical regions. This genera is found to be a rich source of biologically active natural products such as triterpenes, flavonoids and steroids. As a part of our continuing search for novel insecticidal compounds from Indonesian Kalanchoe plants, we examined Kalanchoe daigremontiana collected from Bandung region, West Java, Indonesia. The methanolic extract of the dried leaves of K. daigremontiana was concentrated and extracted with methylene chloride The methylene chloride extract exhibited an insecticidal activity toward silkworms. The methylene chloride extract was partitioned between n-hexane and methanol containing 10% water. The active lower layer was extracted with ethyl acetate. By using the insecticidal activity to follow the separations, the ethyl acetate fraction was separated by combination of column chromatography on Kieselgel 60 and ODS to afford two insecticidal bufadienolides 1 and 2. The structures of these compounds were elucidated based on spectroscopic analysis (UV, IR, NMR, 2D-NMR) and comparison with those related data previously reported. In this paper, the isolation, structural elucidation, and insecticidal activities against the third instar larvae of silkworm will be described.]]>

<![CDATA[The algae blooming, which is well known as eutrophication, becomes major problem for most water systemsaround the world. Even though orthophosphate caused eutrophication has been removed, eutrophication couldstill occur seasonally due to the act of sediment as a source and sink of phosphate compounds. Foreutrophication monitoring, the needs of information of concentration and type of phosphates species areimportant. To minimize contamination and to gain better understanding of sediment-water interaction, the in situtechnique of DGT has been used for determining the concentration and species of phosphates in sediment andoverlying water. The results showed that the concentrations of FRP and FOP in sediment approximately were 3mg/L and 0.5 mg/L, respectively. Under anoxic condition, phosphates could be released from sediment anddiffused into overlying water which was shown by relatively high concentration of phosphates in overlyingwater. Mineralization of FOP has occurred under anoxic condition which was agreed with an increase of FRP atdepth of sediment. The residue of refractory organic phosphates species were detected at depth sediments alongwith the end group of polyphosphate at deeper sediment. By understanding the role of sediment, its interactionwith overlying water and determining the phosphates concentration and species, eutrophication could becontrolled.]]>

<![CDATA[It has been demonstrated in this work that commercial hollow cathode discharge lamps can be used for LaserInduced Fluorescence technique by sending the laser beam into the cathode discharge lamp. Experiments havebeen performed using a single mode diode laser to investigate selected lines of argon (~772 nm). After resonantlaser excitation on a certain transition, most of the other lines in the spectrum change their intensities in the LIFexperiment. The highest intensity increment is observed for the wavelengths which originate from the sameexcited level (2p7) as the one accessed by the pumping radiation. Further very strong intensity changes areobserved for transitions from the excited levels nearest to the pumping level, obviously due to collisional transferprocesses.]]>
