Abstract

ABSTRACTPotency of Hypertolerance of Calopogonium mucunoides, Centrosema pubescensand Cajanus cajan . Grown on Gold Mine waste Media Contaminated by Cyanideand Mercury. Cleaning up contaminated environment by using green technology ofphytoremediation is urgently needed in the future. These plants will be utilized ashyperaccumulators for cleaning up the contaminated sites. The results of plant screeningshowed that some plant species, which grow in the contaminated areas, indicated hightolerance and potentially effective in accumulating cyanide and mercury in their rootsand above ground portions. Those plants are Calopogonium mucunoides and Centrosemapubescens. This research aims to examine the potency of three candidate plants i.eCalopogonium mucunoides, Centrosemapubescens and Cajanus cajan, that were grownunder three different media i.e tailing waste of PT ANTAM contaminated by cyanide,public mine or PET1 waste that were contaminated by mercury and non contaminated topsoil as a control. The results showed that all of the species were able to grow undercontaminated media and showed a considerable tolerance by indicated high cyanide andmercury accumulation in their shoot and root. Among those three plants, Centrosemapubescens showed the highest level of cyanide and mercury accumulation i.e 3.29 mg I- CN (in the shoot), 34.72 mg I- Hg (in the shoot) and 17.47 mg lk Hg (in the root),followed by Calopogonium mucunoides i.e 14,97 mg I- CN (in the root). Concentrationratio of CN and Hg accumulation in shoot/root of Centrosemapubescens was >I indicatingthat this plant, according to the definition can beconsidered as a hyperaccumulator.Key Words: Calopogonium mucunoides, Centrosemapubescens, Cajanus cajan, mercury,cyanide, waste

Abstract

ABSTRACTHepatitis C virus (HCV) is the major causative agent of chronic liver disease. Recently, the inhibition of NS3 RNA helicase/ATPase activity is being explored as the specifically targeted antiviral therapy (STAT) against HCV infection. This study was aimed to elucidate potential candidates for anti-HCV therapy derived from Indonesian indigenous microalgae. The microalga designated as BTM 11 was isolated and cultured. Methanol extract of BTM 11 was screened as the opponent of purified HCV NS3 RNA helicase enzyme through colorimetric ATPase assay. Screening of chemical compound and fractionation by using gel filtration chromatography with eluent of methanol : chloroform (1:99) were conducted for identification and isolation of the bioactive compounds. The third fraction of fractionated sample showed a relatively strong ATPase inhibitory effect (81.23 ± 2.25 %) compared to the negative control. Further analysis of third fraction using thin layer chromatography (TLC) with eluent of chloroform : methanol (9:2) gave two spots with the Rf value of 0.8 and 0.37, respectively. In addition, high performance liquid chromatography (HPLC) analysis showed absorption peak with the highest abundance at the retention time of 12.483 and 16.617 minutes which absorbed at 266 and 230 nm wavelenght, respectively. According to those analyses, this study suggests that bioactive compounds derived from BTM 11 were classified as the groups of flavonoids and feasible as potential candidates for anti-HCV therapy through the inhibitory effect of NS3 RNA helicase/ATPase activity. Keywords: Hepatitis C Virus, NS3 RNA helicase, ATPase, Microalga, Flavonoids

Abstract

ABSTRACTFeeding Behaviour Activity of Slow Loris (Nycicebus coucang coucang) at Night inCaptivity. Slow loris (Nycticebus coucang) is an endangered tropical primate, with itsdistribution in Indonesia stretch from Java, Sumatra to Kalimantan islands. Population declineare mainly due to habitat destruction, competition in feed and space and live capture to be soldas pet animals. One of the strategies to conserve the species is through captive breedingprogram (ex situ). Understanding the behaviour of slow loris in captivity, especially theirfeeding behaviour, will provide valuable information for obtaining maximal management. Thestudy was conducted at Mammals Captive Breeding, Pusat Penelitian Biologi-LIP1 in Bogor,for three months. Three adults slow loris consisting of two males and one female, were placedin individual cages and observed their nighttime feeding behaviour. Feeds that were givenconsisted of banana, marquise, guava, coconut, papaya, sweet corn, bread and quail eggs. Onezero sampling method was used in the observation with fifteen minutes interval. The resultsshowed that night feeding activity took place 12.44% of the total activities, with the highestactivity took place between 18.00-19.00 WIB as much as 6,1%. Drinking activity took placeonly 0,21% of the total activities, with defecation and urination activities were noted only3,84% and 2,73%, respectively. Others activities, such as locomotion, grooming and restingwere 14,59%, 58,08% and 8,12%, respectively, of the total activities.Keywords : Slow loris, Nycticebus coucang, captive breeding, behaviour, activities

Abstract

Bats utilizing resources together will differ morphologically, ecologically, and behaviorally. This study aimed to measurespecies diversity and to investigate resource use by Megachiropteran bats. Data were analyzed using Principal ComponentAnalysis (PCA), Canonical Correspondence Analysis (CCA), Correspondence Analysis (CA), euclidean distance, chisquare, Anova, and niche overlap index. The result showed seven bat species were captured in three habitat types. Plant asfood identified from pollen comprised 55 species from 29 families and 11 types of corolla. Dobsonia magna and Rousettusamplexicaudatus preferred mixed fruit plantation, whilst other bat species tended to choose primary forest. Dobsonia minortended to have high niche overlap against Macroglossus minimus and Nyctemene aello. According to similarity of foodresource niche, Dobsonia magna, Dobsonia minor, and Macroglossus minimus tended to closely associate, in contrast,Rousettus amplexicaudatus, Nyctemene albiventer, Nyctemene aello, and Syconicteris australis were groupedcorrespondingly. Niche overlap index of food resource among bat species were overall less than 50%. This indicated thatthere was no interspecies competition to food resource. Coronoid process height (CPH), maximum zygomatic breadth(MZB), and condyle to canine bite point (CC) were craniodental morphology variables which did not describe certaincorolla types.Keywords: species diversity, resource use, niche overlap, Megachiropteran, Gunung Meja

Abstract

ABSTRACTCapability of Nir-Conservation Area for Preserving Jawa Lowland Endemic: CaseStudy in Kebumen District. Indonesia region is inhabited by 1.598 birds which 372 Indonesianendemic birds and 56 species of them are Jawa endemic. Amongs of jawa endemic birds, 19species are lowland occupant. Indeed the birds play important roles in ecosystem as agents ofpest population control, pollination, and seed dispersal. In lowland area of Jawa, intensivetransformation of land use exacerbated by no conservation area may threaten presence of theendemic birds. This study aims to assess caring capacity of disrupted area in low lands forpreserving endemic birds of Jawa.The study was conducted in Bedegelon river covering northern mountaneus area ofKebumen district from October-November 2007 using encounter rates methode. Survey wascarried out in three farm types: agroforestry (wanatani), intercropping agriculture area(tumpangsari) and mixed area of vegetation-settelment area (sempadan sungai).Result shows that four spesies Jawa lowland endemik birds was found in observed area.Lonchura leucogastroides and dicaeum trochileum found at all farm type, Prinia familiarisfound at intercropping agriculture area (tumpangsari). Alcedo coerulescens were observed atagroforestri area (wanatani) and mixed of vegetation-settelment area (sempadan sungai) farmtype.Key words : Jawa endemik birds, diversity, Jawa lowland, farm tipe, kebumen district

Abstract

In Indonesia, data on the phenotype of AI virus subtype H5N1 is very limited, due to the facilities for such testingshould be performed in a laboratory Biosafety level III. Additionally influenza virus has a high error rate duringtranscription of their genome has low RNA polymerase. High error rates generate quasispecies. In this study, wedid some H5N1 viruses infection with different genetic variations and conducted DNA sequencing in severalorgans. To determine the possible emergence detection of quasispecies in different organs and until the virus wasexcreted. We tested the hypothesis that the quasispecies might arise from virus that was infected to theexperimental animals. The results of this study showed that the AI virus subtype H5N1 had different phenotypes inanimal depending on their genetic character. AI virus subtype H5N1 killed chickens within 48-72 hoursdepending on the genetic character of the virus. New AI viruses of subtype H5N1 caused more severe organdamage severe than the character of the old AI viruses. Adaptation of virus in each organ also proved that the viruslikely create variations/quasispecies, which was different from the viral origin.Keywords: Phenotypes, avian influenza, H5N1, genetic character, quasispecies

Abstract

Vocalizations of Microhyla achatina have never been described before. The advertisement calls of six individual malesof M. achatina which originated from the foot hills of Mount Salak, West Java were recorded in September 2011 atair temperatures of 21.0°C-23.4°C. Call components were obtained from 95 calls, consisting of 855 pulses, whichwere then analyzed to obtain the characteristics of sound waves by using software of Adobe Audition 3.0 andSAP2011. Sound waves of M. achatina mainly consists of impulses whose sound spectrum ranges from 1327.5-2789.1 Hz, while the band width of the spectrum is 1461.6 Hz. Results of the analysis showed that the frequency ofthe three pulse-forming elements (dominant frequency, maximum frequency and minimum frequency) was markedlymodulated; frequency modulation was clearly visible in the minimum frequency, which was modulared by 1500 to2700 Hz modulation. The modulation of the dominant frequency and the maximum frequency was not too broad,i.e. between 3000-3500 Hz. Results of linear regression analysis of the dominant frequency versus minimum frequencyand dominant frequency versus maximum frequency showed a strong correlation between the dominant frequencyversus minimum frequency, but a weak correlation between the dominant frequency versus the maximumfrequency.Keywords: vocalization, Microhyla achatina, West Java.
