Abstract

Efficacy and quality of medicinal plant extracts depend on chemical composition therein. Therefore, to ensure its efficacy orquality, the chemical composition of extracts have to be analyzed based on its chemical marker or its chemical pattern. This study tried to develop a method for extracts quality assay based on infrared spectrum in fingerprint region and extracts inhibition activity to xanthine oxidase. Five extracts from kunyit (Curcuma domestica), temulawak ( C xanthorriza), jahe (Zingiber officina/e), temukunci (Boesenbergia pandurata), and cabe jawa (Piper retrofractum) were tested to inhibit xanthine oxidase activity. The bioactive data of extracts and its infrared spectrum was analyzed using PCA and PLS-DA (partial least squarediscriminant analysis). Almost all extracts that were tested showed inhibition activity to xanthine oxidase activity, except the extract of jahe. The result showed that PCA can group all of extract into each of their region. Meanwhile, PLS-DA has shown to be a good prediction model for classifying extracts based on fingerprint region of its mR Spectrum and its biological activity. Keywords: fingerprint, mR spectra, compound marker, xanthine oxidase

Abstract

Accurate and up-to-date information of marine resources is needed for optimum resource utilization. If the required information cannot be obtained with traditional field surveys, remote sensing as a tool for providing fast, efficient, and accurate information is used to detect the changes. The study aims to use remote sensing data for assessing distribustion and condition of marine resources in Nias waters before and after tsunami. Marine resources pararameter derived remote sensing data are sea surface temperature (SST), suspended solid matter, chlorphyll-a concentration, coral reef and mangrove distributions. Mapping and differences in coral reef and mangrove distribution were evaluated using two scans of Landsat image in 1989 and 2005. Sea surface temperature was derived from NOAA-AVHRR data, and chlorophyll-a concentration was derived from SeaWiFS data. The study showed that there were no significant changes of coral reef and mangrove distribution, SST, chlorophyll-a concentration after and before tsunami. Spectral analysis of SST and chlorophyll-a showed that the variability of the parameters was affected by monsoon system and global climate change, namely El Nino Southern Oscillation and Indian Ocean Dipole.Keywords: remote sensing, satellite, Nias, tsunami, chorophyll-a, coral reef, mangrove

Abstract

Social networking and conflict understanding in rural community is the important step in finding strategy of conflict resolution. Through qualitative research technique, it is known that there is a relation between the flow of people who were going out-in Saparua Island to fill their needs, change into flow and networking of people who were coming home to rural areas which create conflict. All villages, so called negeri, which are known by Saparua Island community, get the impact of social networking which creates conflict. Social conflict which first based on agrarian problem then developed and added with the impact of religion and politic problem, just like conflict source in Ambon Island. Although, in the next development kinship and adat relation are taking important role in taking care of community rules. The strategy needs to be followed by establishment of natural resources and land property rights existence of society. Without this step, rural community in Saparua Island still has conflict potential. Process of this step needs to be done equal with adat relation development in Latupati Association level. With that step, rural community of this island will have social institution as a forum to have root communication. An institution which can be potency of society prevents sustainable and  long  reconflict.   Keywords: Social Networking, Conflict Resolution, Conflict in Rural Area, Saparua

Abstract

Rainfall zoning analysis with fuzzy clustering method has been performed at the centre of paddy area in the northern coast of Banten Province and West Java Province. Rainfall data recorded in the 1980-2006 period from 62 rainfall stations in the northern coast of Banten Province and from 75 rainfall stations at Karawang and Subang in the northern coast of West Java Province have been used in this analysis. For the first analysis a calculation of arithmetic mean values representing EI-Nino, La-Nina and Normal condition has been performed. Next, a fuzzy clustering analysis is applied to these mean values. The clustering analysis consists of two steps. First, a symmetric and reflective compatibility relation matrix describing a distance function between rainfall stations is calculated. Second, a fuzzy equivalency relationship i.e. a transitive approach of fuzzy compatibility matrices is determined. The results of analysis indicate a difference in the equivalency level among the stations under the EI-Nino, La-Nina and Normal conditions in the northern coast of Banten Province and West Java Province. Based on the 75°/o equivalency level, in the northern coast of Banten area can be grouped into four rainfall zones under EI-Nino condition, two zones under La-Nina condition and three zones under Normal condition. On the other hand, in the northern coast of West Java area can be grouped into three zones under EINino condition, two zones under La-Nina condition, and four zones under Normal condition.Keywords: Arithmetic means values, EI-Nino, La-Nina, Fuzzy clustering, Rainfall zoning

Abstract

Kacang goat is one of Indonesian local goat which has not been optimized in exploration. Kacang goat has potency as a dairy goat. Milk and colostrum from this type of goat is one of lactoferrin sources which has various benefit, such as antimicrobial activity. The milk as a lactoferrin source is expected to be a solution for bacterial 9astrointestinal infection cases which is a major problem in Indonesia. This research described the identification of lactoferrin from milk and colostrum of kacang goat by single radial immunodiffusion (SRID) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). SRID is based on the diffusion of whey protein from a circular well into a homogeneous gel containing anti-lactoferrin. SDS-PAGE was performed in 7.5%  polyacrylamide gel. Both methods were able to identify lactoferrin in colostrum and milk from the sample, but SRID showed low sensitivity toward low concentration of lactoferrin in both colostrums and milk. The estimation of lactoferrin molecular weight by relative mobility of protein from the bands that perform of colostrum and milk of kacang goat is approximately 74,100 Dalton. Based on the ring diameter of the precipitin, the lactoferin level in colostrum and milk increased until 48 hours after postpartum and subsequently decreased. Keywords: colostrum, milk, kacanggoat, lactoferrin, SRID, SDS-PAGE

Abstract

Patchouli oil is one of major components in perfumery industries as well as incense. Its smell is heavy and strong due to the presence of its major component called patchoulol or patchouli alcohol. However, the production has not stabilized yet because of several factors including cultivation. Experiment was conducted from November 1999-May 2000. Patchouli cuttings were grown in randomized complete block design with four replications. Nitrogen rates for this experiment were 0, 45, 90, and 135 kg ha-1 and three harvesting methods, which were three pairs of youngest leaves, 20 em from the tip and by leaving 20 em stubble from ground. Plant height and number of branches continued to increase significantly linear at higher N rates. There was significant interaction between N rate and harvesting method on wet and dry harvest mass. Effect of N on composite percentage differed for each harvesting method. The yield from three youngest leaves was higher than harvesting 20 em from the tip and leaving 20 em stubble from the ground for 45, 90, and 135 kg ha-1 respectively. Keywords: patchouli oil, nitrogen level, harvesting method

Abstract

Paederus fuscipes is an important predators in soybean fields, including toward Helicoverpa armigera. Predation evaluation using a cage are very common, giving significant suppressed the exposed pest population. However, predation evaluation in open space is rarely conducted. This study was to investigate the dispersal capability of P. fuscipes, and to evaluate the effectiveness of the beetle release in the predation on H. Armigera eggs and larvae. Observations were made in a soybean field in Mekarwangi Village, Cianjur, during soybean planting season in 2005 and 2006. In the dispersal study, all beetles were collected from the field and tagged on the elitra. As many as 1187 tagged beetle were released. The dispersal was observed in the area within a radius of 40 m from the release point. In the predation study, eggs and larvae of H.armigera from laboratory rearing were used as the prey. Soybean plots with exposed prey were treated by releasing the beetle with different densities, i. e., 100-400 beetles, and a control. The released beetles were from laboratory rearing and beetles were collected from the field. The study indicated that the tagged beetles that were released to the soybean field actively move but their dispersal were relatively slow. Until 5 days after release, most beetles were remain in the area surrounding release point, within a radius of 5 m. Release of predators to the soybean field, suppressed H. armigera egg and larva populations for both vegetative and generative stages, but were not significantly different between treatment and control plots, except for the egg population on vegetative stage. It indicates that population of the natural predator in soybean field were very complex and potential to be used for controling pest populations. Thus, it is important to manage soybean field that can support the role of predators in the field. Key words: predator release, Paederus fuscipes, predation, Helicoverva armigera

Abstract

 The curing process of vanilla beans from dried vanilla to vanilla extract would give added value to vanilla products. Aroma and taste in vanilla extract depend on variety of plants, cultivation methods, and curing process. Indonesian vanilla extract tend to give woody and phenolic aroma because it was harvested too early and it did not cure perfectly. This study was to identify the physicochemical and aroma characteristics of vanilla extracts from importer, exporter, and vanilla extracts from the newest experiment from our laboratory. There  were seven samples, three from importers (Tahiti grade I, Tahiti grade II, Virginia Dare), two from Indonesian Vanilla exporters (Djasula Wangi, Cobra), and two from our laboratory (G11, 57). The  physicochemical characteristics which were analyzed were vanillin content, ash, soluble ash, alkalinity of soluble ash, alkalinity of  total ash, total acidity, and lead number, all compared with the Food and Drugs Administration (FDA) standard. Sensory analysis used aroma description test consist of qualitative descriptive test (in-depth interview and focus group methods) and quantitative descriptive analysis. The result showed that the laboratorys sample from modified curing process (G11) followed the FDA standard in physicochemical characters, but the aroma description was not as strong as the aroma of vanilla extract from exporters, namely Cobra with creamy, sweet, and vanilla aroma; and vanilla extract from importer, namely Virginia with smoky and spicy aroma.   Keywords: vanilla extracts, aroma
