Abstract

Patchouli oil is part of the essential oils obtained from patchouli plants by distillation. Patchouli oil is widely used in industry as provider of aroma and flavour. Quality of patchouli oil is determined by its natural characteristics and foreign materials contain in the patchouli oil. The foreign materials contain in the patchouli oil can be damage the quality of patchouli oil. Aceh Province is the largest contribute in producing patchouli oil in Indonesia. Patchouli oil processing areas in the Aceh region, precisely in the North Aceh and South Aceh district. In generally farmer of patchouli in Aceh is traditional farmer and many of them not yet follow the best refine system. They do it base of previously experience. Refinery equipment that used from former drum that can be reaction with patchouli oil, with the result can to change chemistry structure of patchouli oil, so that the oil produced is dirty and has dark colour and does not meet the specified quality requirements). The main purpose of this research is to increase yield and the quality of patchouli oil by using of refinery equipment modification process to meet quality standards. In this research the former drum is replaced by stainless steel drum. Method of test quality and procedure of test quality same as standard method of SNI-06-2385-2006. The results showed that the using of refinery equipment (stainless steel drum) able to increase the yield and oil quality, especially in terms of colour, physicochemical properties and concentration of its main components and also meet the quality requirements of national standards

Abstract

The objectives of this study were to determine the current bird species present in the study areas and to analyze variation of feeding guilds in different habitat types. Point count and mist-netting methods were used for bird census in SF and OP, while only point count method was used in PF. Feeding guilds were determined for each species recorded. A total of 183 species representing 49 families were recorded at all study sites. Secondary forest scored 106 species, followed by PF with 70 species and OP with 58 species. The highest abundance of bird families observed in SF was Pycnonotidae (26.65%), Hemiprocnidae (19.77%) and Muscicapidae (7.10%); in OP, Pycnonotidae (21.59%), Muscicapidae (19.12%) and Sturnidae (17.95%); in PF, Ardeidae (29.09%), Sturnidae (10.15%) and Hirundinidae (7.86%). Alternative hypothesis established that the abundance of species is different across habitat types, F(2,105) = 99.83, p 0.05. Eight feeding guilds were identified in paddy field and seven in both secondary forest and oil palm plantation. If forests were converted to OP feeding guild could possibly change with a decreased in insectivore, insectivore-frugivore, insectivore-nectarivore and frugivore species; and increased in carnivore, grainivore and omnivore species. If forests were converted to PF feeding guild could possibly change with a decreased in insectivore, insectivore-frugivore and frugivore species; and increased in carnivore, insectivorenectarivore, insectivore-grainivore, grainivore and omnivore species. Comparison between SF and OP with Mann-Whitney U-test showed significant differences in six feeding guilds, including insectivore, insectivore-frugivore, insectivore-nectarivore, frugivore, grainivore and omnivore. Comparison between SF and PF showed significant differences in five feeding guilds, comprising of carnivore, insectivore-grainivore, frugivore, grainivore and omnivore. Comparison between OP and PF showed all feeding guilds to be significantly different. Complex vegetation in forestoffers more niches, with higher plant and insect diversity to support more bird species. In contrast, PF, a temporary wetland, support predominantly various waterbirds and migratory species.

Abstract

Inappropriate uses of antimicrobial drugs have contributed to the development of resistant microbial pathogens. This phenomenon requires discovery and development of potential antimicrobial compounds from organic materials. Lumbricus rubellus is the ubiquitous earthworm containing antimicrobial peptide named Lumbricin-1. The aim of this study was to determine the broad spectrum antimicrobial activity of Lumbricus rubellus powder against several drug resistant microbes such as Multidrug Resistant (MDR) Pseudomonas aeruginosa, Methicillin Resistant Staphylococcus aureus (MRSA) and Fluconazole resistant Candida albicans. This experimental study was conducted using Completely Randomized Design (CRD) with 6 treatment groups consisting of 100 mg, 200 mg, 300 mg, 400 mg and 500 mg L.rubellus powder in 5 ml solvent (acetic acid and acetonitrile) and negative control groups. One percent of each concentration then was used in the antimicrobial activity testing using Kirby Bauer disc diffusion method. Data of this research were analyzed by ANOVA. The results showed that L. rubellus powder in each of the concentrations of 100 mg, 200 mg, 300 mg, 400 mg and 500 mg obtained an average inhibition zone of 14.33 mm, 14.17 mm, 14.00 mm, 15.00 mm and 13.00 mm respectively against MDR P. aeruginosa; 16.75 mm, 18.50 mm, 18.75 mm, 16.75 mm and 17.25 mm against MRSA; 16.50 mm, 18.00 mm, 17.50 mm, 17.75 mm and 16 mm against Fluconazole resistant C. albicans. Statistical analysis revealed that Lumbricus rubellus powder in the tested concentrations showed significant broad spectrum antimicrobial activity against drug resistant microbes (p0.05).

Abstract

Malaria, an infectious disease causes by Plasmodium, contribute to 300-900 million morbidities and 1-3 million mortalities, annually. This study aimed to determine the Rubella vaccine potency to inhibit Plasmodium berghei merozoite invasion to erythrocyte which evaluated from parasitemia levels, mortality and mice clinical condition. This study conducted in mice injected Rubella vaccine prior injected with P. berghei. There were four groups: A, B and C injected with 500 µl, 2 µl, and 1 µl rubella vaccine respectively. Group D injected with 500 µl sterile aqua, as control group. After 28 days of vaccination all mice injected with 0.2 ml P. berghei. Furthermore, we observed to parasitemia levels, death, and clinical condition of mice to assess Rubella vaccine effectiveness to inhibit merozoite invasion. The results shown Rubella vaccine did not provide significant effect on parasitemia levels. It might Rubella vaccine dose we used under effective dose and less effective of target site. However, our study shown Rubella vaccine provided significant effect on mice mortality (p0.05). It is probably due to Rubella antigen (213-239 amino acid sequence) and malaria antigen merozoite surface protein (MSP)-119 (sequence amino acid 238) has similar structure, thus it was likely generated cross-immunity. In conclusion, 28 days Rubella vaccination did not provide significant effect on parasitemia levels, however it provided significant effect on mice mortality with infected by P. berghei.

Abstract

Coccydynia is a term that refers to a painful condition in and around the coccyx. This symptom is typically a discomfort or pain which is felt when sitting for long time and when rising from sitting position. Many physiologic and psychological factors contribute to its etiology, but the majority of cases were found to be aggravated by pregnancy and childbirth (postpartum). Luxation and fracture of the coccyx are the two most common lesion of postpartum coccydynia. This poster shows an anatomy overview especially the coccyx to increase the understanding about this symptom

Abstract

Rapid developments in biotechnology increase the demand to separate biomolecules using mild process conditions. The separation of lysozyme by mixed matrix membrane adsorbers was studied. MP500, a strong anion exchange resin is incorporated as adsorbent into an EVAL polymeric matrix. The membranes in this study are prepared by immersion precipitation out of a DMSO solution containing 14% EVAL. All membranes contain 65% resin based on dry solids. The morphology of the membranes are characterized using scanning electron microscopy. Dynamic adsorption capacities of lysozyme onto mixed matrix membrane adsorbers are measured. The dynamic lysozyme adsorption capacity at 10% break through is determined as 43 mg lysozyme/g membrane.

Abstract

Northern Australia contains a rich freshwater biodiversity due largely to low levels of human impact. Most rivers remain unimpacted and free-flowing. The latter characteristic is important as it ensures that natural levels of connectivity throughout the riverine landscape exist and organisms and, importantly,carbon and nutrients, can be shifted between ecosystems and different parts of the landscape. This high degree of connectivity differs between rivers according to their flow regime however; most rivers of northern Australia are highly seasonal and flow intermittently. The present paper details the importance ofmaintaining connectivity within the river and between the river and its floodplain for the maintenance of species diversity and the structure of aquatic food webs. It draws upon large datasets concerning fish biodiversity and several foodweb studies using stable isotopes assembled or conducted with the TropicalRivers and Coastal Knowledge program to illustrate the importance of connectivity

Abstract

The research has been carried out in the laboratory scale to create and assess the ability of membrane cellulose from nata. Nata was produced from coconut-water and nira aren with a ratio 100%: 0%, 0%:100% and 50%:50%, which fermented with the addition of sugar and without the addition of sugar. Acetobacter xylinumwas added in medium as starter. The fermentation process was be done at 5, 7 9 days. The objective of this research was to study the influence of membrane cellulose as filter for Pliek U oil. Pliek U oil was filtered through membrane cellulose. Pliek U oil which was resulted have a good quality than before. Where membrane cellulosehas been able to reduce Free Fatty Acid (FFA), the results showed that the use of membrane cellulose from nata significantly reducesFree Fatty Acid (FFA). The membrane cellulose from coconut-water and nira aren without the addition of sugarat 9 days was reduced Free Fatty Acid from 2,43 % to 1,2%. But for density and index bias of Pliek U oil does not reduced with using membrane cellulose

Abstract

Rubber seed will loose its storability in a short time. Seed germination and fungal attack were factors that barrier the storage period. The research aim was to test the ability of the potential osmotic solution and fungicides to reduce seed germination. Completely randomized design with two factors and three replications, i.e: PEG 6000 (w/v): 0%, 15%, 30%, 45%, 60% (potential osmotic solution) and fungicide (active ingredients were pyraclostrobin + metiram ) (g / 1 kg seed): 0 g, 10 g, 20 g, 30 g and 40 g, were applied.The results showed that PEG 30% can inhibit seed germination up to 9.07% and 37.47% and fungicides 40 g/1kg can reduce fungal attack during storage of 12 and 16 days.  Combination of PEG-6000 30% and fungicides 40g / 1 kg could maintain seed storability by pressing the seeds germination up to 10.67% and fungal attacks up to 18.00% during storage of 16 days with 96.80% germination.
