Abstract

ABSTRACTThe Effect of Environmental Factors on the Horizontal and Vertical Movement of Frogs. Fourenvironmental factors (moon phase, air temperature, water temperature and air humidity) weremeasured to determine the impact of environmental factors on the dynamics of horizontal andvertical spread of the frog Rana erythraea, R. nicobariensis and Occidozyga lima in a wetlandarea of Ecology Park, LIPI Campus Cibinong. Observation was done follows transect line(100 meters long) and set along the edge of the lake where the habitat was more diversecompared to the other sites. Observations were carried out from July to November 2009. Theposition of individual frogs (distance from water?s edge and height from the ground or water)was recorded and then grouped into intervals of 100 cm distance and height each. Correlationanalysis between the number of individuals per unit distance or height with environmentalfactors was measured using the statistical program SPSS version 16.0. The results of thisstudy proved that the air and water temperature as well as air humidity have significant effecton horizontal and vertical ecological distribution of R. erythraea and R. nicobariensis; whereasfour environmental factors had no impact on horizontal distribution of O. lima. The movementof R. erythraea was strongly positively correlated with air temperature, but strongly negativelycorrelated with air humidity; however the abundance of R. nicobariensis was strongly negativelycorrelated with air temperature and strongly positively correlated with air humidity. Mixedvegetation of species Leerxia hexandra and Eleocharis dulcis at a distance between 0-100 cmfrom the edge of the water and height between 0-100 cm from the ground constituted thepreferred microhabitat of frog species R. erythraea and R. nicobariensis.Key words: Environmental factors, Rana erythraea, Rana nicobariensis, Occidoziga lima,Ecology Park, wetland.

Abstract

ABSTRACTPotency of Hypertolerance and Metal Absorption of Some Plant Species Under GoldMine Waste. Degraded mined land is characterized by extreme of alkalinity or acidity, highconcentration of soluble salt and high concentration of heavy metals. Contamination of minedsoil and water affects not only on agriculture system but also on food chains andepidemiological problems. As soil metal can not be biodegraded, remediation of soil heavymetal risk has been a difficult and expensive goal. Remediation of hazardous soil is requiredto reverse the risk to humans and the environment. Recently there are several differentstrategies available for the clean up and restoration of contaminat6d soils i.e conventionalwhich is mainly engineering-base and phytoremediation which is a biological-base method.Phytoremediation is defined as: clean up of pollutants mainly mediated by photosyntheticplants.. In this research four species of plants i.e Mimosa pigra, Crotalaria juncea, Crotalariasp. and lpomoea sp. were studied their potencies as hypertolerant plants on the waste of PTANEKA TAMBANG and public mines of Pongkor and Cigaru. The results showed that theplants were able to grow and showing high tolerance to the contaminated media. The mosttolerant species was lpomoea followed by Crotalaria and Mimosa. The results raised someprospectsfor phytoremediation technology for rehabilitating contaminated mined lands.Keywords: Phytoremediation, hypertolerance

Abstract

Tree architectural model is basically a tree construction as a result of meristematic growth pattern. Tree architectureis closely associated with water and soil components, i.e. rainfall, throughfall, stem flow, infiltration, surface run-off,and erosion. For Altingia excelsa (Rasamala) plots, the results showed that the daily average of the rainfall intensityobserved was 9.67 mm, stem flow 0.03 mm, canopy throughfall 5.43 mm, infiltration 0.51 ml/mm2/second,surface run-off 3.45 mm, and erosion 5.66 kg/m2. For Schima wallichii (Puspa), the daily average of rainfall was9.67 mm, stem flow 0.04 mm, canopy throughfall 4.02 mm, infiltration 0.49 ml/mm2/second, surface run-off 8.18mm, and erosion 12.71 kg/m2. Compared to A. excelsa, S. wallichii significantly had larger values in someparameters measured, i.e. stem flow, surface run-off, and erosion, indicating that on land sopes of 70% of theMount Gede Pangrango National Park, individual plants of S. wallichii seemed to be well adapted. However,individuals of A. excelsa possessed a more spreadly branching model, larger vertical width, denser canopy, andskewed bark channels capable for slowing down the stem flow and canopy throughfall. Consequently plants of A.excelsa would generally be able to hold and conserve water and soil better than S. wallichii plants.Keywords: Tree architectural model, stem flow, throughfall, surface run-off, infiltration, erosion

Abstract

ABSTRACTSimeuleu island is located in the western part of Sumatera belonging to Aceh Province. Floristic and phytososiological information of vegetation in Simeuleu island is limited and not much study has been conducted, especialy trees species group (diameter ?10 cm). Two  study plots were used: one hectare at Kuala Makmur forest and one ha at Alafan forest (100 m × 100 m). Density analisys at Kuala Makmur recorded 329 individuals/ha while at Alafan consisted of 377 individuals/ha (average of 353 individuals/ha).  Total basal area at Kuala Makmur 29.48 m2/ha while at Alafan  was 44.28 m2/ha (with an average of 36.88 m2/ha). The Shannon-Wiener diversity index (H?) at Kuala Makmur was 2.94 and at Alafan was 2.73 (whit an average H?of 2.84). The total canopy heights of the two study sites as were relatively similar consisting of four strata. Dominant species occurred at Kula Makmur was Shorea atrinervosa (Importance Value, IV=83.55%) and at Alafan was Dipterocarpus grandiflorus (IV=128.06%). Dominant familly at Kuala Makmur was Dipterocarpaceae and at Alafan was Ebenaceae. The distribution of dominant tree species at Kuala Makmur is less prevalent than at Alafan.  Keywords: Simeuleu, Aceh, trees structure, species richness, lowland forest.

Abstract

Maluku as a major producer, reached the highest production of siput lola (T. niloticus) in 1989 with production about 250tons (6.8 billion) but then drastically decreased to 14.2 tons in 2005. This study was conducted over 16 months (March2012 - June 2013) in the waters of the Banda Islands. The purpose of the study was to determine the individual andpopulation growth of trochus snails. Individual growth rate (K) of siput lola resource for deameter basalt (DB) was equal to0.2439 (von Bertalanffy models) and 0.3571 (Gompertz models). Maximum size (S?) that could be achieved for deameterbasalt was equal to 91.73 mm (von Bertalanffy models) and 88.52 mm (Gompertz models). The population growth rate(r) of siput lola resource was at 0.1469 with a maximum amount that could be reached as many as 401 ind or 122ind ha-1 (von Bertalanffy models) and 191 ind or 58 ind ha-1 (Gompertz models) within a period of 24 months.Keywords : Growth, Trochus niloticus, Banda Naira islands

Abstract

ABSTRACTThe natural dissarter and Land Slide at Ciremai Mountain National Park. Kuningan region,West Java, has relatively highly potential on the seismic and land slide hazards. This region issituated on the active tectonics, deep slopes and generally composed by volcanic sediments ofCiremai volcano. All of those factors are, even more, situated on the annually high rainfallregion. The fractures and deformation of the soil and landforms triggered by the earthquakesalso an important factor facilitate the land slides.Keyword: Kuningan, West Java, seismic hazard, earthquake,land slide hazard

Abstract

ABSTRACTThe genotypic diversity showed by the hybrid crossbreed of transgenic Mutiara (carrying African catfish growth hormone) with non-transgenic catfish (Mutiara or Sangkuriang strain) high enough (many polymorphic fragments) in the first offspring. The aims of the study were to detect genotypic diversity from Sangkuriang catfish, transgenic Mutiara, non-transgenic Mutiara and first offspring (hybrid F1) with RAPD (Random Amplified Polymorphic DNA) marker using 2 primary types (OPA-03 and OPA-06). Experimental method is exploratively used in this research with qualitative descriptive analysis. The amplification results show the OPA-03 primer (5'-AGTCAGCCAC-3 ') is the best primer that visualizes fragments (polymorphic and monomorphic) in all samples. The genetic relationship of the test fish using the NTSYSpc program shows that the OPA-03 phenogram in the first progeny of crossing the transgenic Mutiara male and Sangkuriang female has more genotypic diversity than other crosses. The first offspring of the broodstock crosses of the same strain (Sangkuriang and Sangkuriang) had a kinship of 70%, the crosses between non-transgenic Mutiara with Sangkuriang had 79% genetic similarity. The highest genetic similarity index (82%) was obtained from the first progeny of crossing transgenic Mutiara with Sangkuriang.Keywords: polymorphism, RAPD, phenogram, crossing, transgenesis
