Abstract

A study on the relationships between prey animals and the occurence of sumatran tiger was conducted in Kerinci Seblat National Park, western Sumatra from May up to September 2001. The data have been collected from eight study sites based on the forest habitat types and its threats. The results showed that frequency of encounters with prey animals in different forest habitats were no difference. This might indicates that the prey animals were distributed fairly in all types of forest habitat. The frequency encounters of the sumatran tiger signs, however, have shown differently between locations. The encounters of tiger signs were more frequent in the forest habitats that close to the streams; in forest habitats with few animal huntings; and in forest habitats with no logging activities. This findings support the hypotheses that the existence of sumatran tiger as a predator is determined by the dense vegetations surrounding streams as hiding place used in an ambush; availability of prey animals as food, and habitat disturbances as shown by logging.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Sumatran tiger (Panthera tigris sumatrae); forest habitat; prey animals

Abstract

The impact of CPO (Crude Palm Oil) dock activity in Mentaya River of Central Borneo caused degradation of ecosystem, particularly on both mangrove and macrozoobenthos community. One of methods used for monitoring of ecosystem degradation was to determine species that were still survive under the polluted conditions. These survival species were assumed to synthesize alloenzyme that can be used as indicator. Alloenzyme was synthesized as an effort of adaptation processes toward environmental pressures caused by CPO spillon Mentaya River. Alloenzyme would be expressed as phenotypic and genotypic adaptation processes or phenotypic plasticity. Research was carried out, consisted of field research included collecting sample and environmental data (oil content, temperature, pH, electric conductivity and redox potential), and laboratory research included series analysis of water quality (DO, BOD, COD, pH, TSS, TDS) and also alloenzyme content of Soneratia caseolaris L. and Macrobrachium rosenbergii de Man. The alloenzyme of root and leaves mangrove and prawn’s hepatopancreas was analyzed using Spencer starch gel electrophoresis modified method of exposed on sucrose solution. Separated components of alloenzyme were detected by special staining for Esterase isozyme. The results revealed that Soneratia caseolaris L. and Macrobrachium rosenbergii de Man were bioindicator organisms for the polluted site by oil spills from CPO loading activities. The polluted river water by oil spill from CPO activities decreased redox potential, DO, increased oil content, DHL, water temperature, pH sediment, pH water, TDS, BOD, COD, TSS. Gel electrophoretical analysis demonstrated that Mangrove Soneratia caseolaris synthesized alloenzyme consisted of complex enzymes such as EST in its root and leave cells. Those enzymes were nearly similar to those of Macrobrachium rosenbergii. The oil spill from CPO have ester bonding so its adaptation mechanism with release Esterase isozyme to hodrolysis process. The similar component of the isozyme are promising enzyme used as a tool for biomonitoring and an effective methods for detection of early river ecosystem degradation.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: CPO, Isozym

Abstract

Asthma is the most common potentially serious medical condition to complicate pregnancy. To date, many attempts have been done to detect genetic loci contributing to asthma susceptibility. HLA-DR loci may play an important role in the pathophysiology of allergic inflammation by influencing specific IgE responses. Asthma affects almost 7 percent of women in their childbearing years. When women with asthma become pregnant, a third of the patients improve, one third worsen, and the last third remain unchanged. Asthma exacerbations are most likely to appear during the weeks 24 to 36 of gestation, with only occasional patients (10 percent or fewer) becoming symptomatic during labor and delivery. Uncontrolled asthma can cause serious complications for mother, including high bloodpressure, toxemia and premature delivery. For the baby, complications of uncontrolled asthma include increased risk of stillbirth, fetal growth retardation, premature birth, low birth weight and a low APGAR score at birth. The goal management of asthma during pregnancy is to achieve optimal therapy, maintaining controlled asthma and increased the mother and baby’s quality of life. Most asthma medicationsare safe during pregnancy.© 2008 Jurusan Biologi FMIPA UNS SurakartaKeywords : Genetic diversity, asthma, pregnancy, managemen

Abstract

Actinomycetes is a major microbial group observed in soil, and contributes to nutrient cycling. This study is intended to verify physiologicalcharacters and phosphate solubilizing ability of Actinomycetes isolated from soil of Raja Ampat, West Papua. Most of isolates (RCW16-9,RCW16-8, W5-6, RCW25-1, RCW26-5, W28-4, W3-1, W3-7, W17-7, and W10-1) belonged to Streptomyces genera. The isolates produceclear zone in Pivoskaya after 3 days incubation. The liquid growth of this isolate rapidly utilizes glucose, and after 24 days of incubationalmost 95% glucose was consumed. Decrease of pH from 6.1 to 4.3 may stimulate dissolution of calcium phosphate, and about 21 mg/L-Pwas observed in bulk solution. An increase of phosphomonoesterase activity during incubation is concomitant with the release oforthophosphate into bulk solution. Acidity of cultures increased may stimulate solubilization of calcium phosphate. Most strains producephosphomonoesterase enzyme, indicating that actinomycetes are important soil microbes responsible for mediation and stimulation of bothinorganic and organic phosphate dissolution. Physiological and biomass growth character of phosphate solubilizing actinomycetes could beimportant taxonomic indicator for identifying and grouping soil actinomycetes.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Actinomycetes, phosphate solubilizer, phosphomonoesterase, glucose

Abstract

This study was conducted to determine the influence of pauh kijang (Irvingia malayana Oliv.) stem bark ethanol extract in decreasing parasitemia in mice infected with Plasmodium berghei. Mice were divided into 6 groups as treatments: (1) negative control (CMC), pauh kijang ethanol extract with the concentration of (2)1, (3)10, (4)100, (5) 1000 mg/kg BW, and (6) quinine as positive control. The result showed that meridian effective dose (ED50) of pauh kijang ethanol extract was 36.95 mg/kg BW. Treatment of 100 mg/kg BW lowered parasitemia level by 63.8%, and this treatment did not give significant different (P>0.05) compared to positive control. The result suggests that pauh kijang ethanol extract had antiplasmodial activity since this extract reduces parasitemia more than 30%.© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Irvingia malayana, antimalarial, malaria, ED50, plasmodium
