Abstract

ABSTRACTSpecies Identification of Scarlet gourd (Coccinia grandis (L.) Voigt) in Three Population inYogyakarta. Papasan is a dioecious plant belongs to the family Cucurbitaceae. This plant iscommonly used as vegetable, anti diabetic, anti bacterial, and anti diarrhea. In Daerah IstimewaYogyakarta, there were two varians of Papasan (Papasan I and II), found in three population(Ngebel, Berbah and Gajah Wong Riverbank). They differ in phenotype, especially in shapeand taste of fruit. Genotype observation using squash method on the root tips with modificationin the duration of maceration were used in this research indicated that cells devided of PapasanI at about 8-11.30 a.m, while Papasan II at about 08.30-09.30 a.m, 11 a.m-00.30 p.m and 2-2.30p.m. The chromosome number of both Papasan is 2n=24, contains of 22 autosomes and 2 sexchromosomes. The karyotype formulas of Papasan I and II were 2n=24=20m+2sm+XX(m).Based on the statistic test, significant difference on chromosomes character between PapasanI and II was only in short arm of autosome pair number 5. The difference R value betweenPapasan I and II was smaller than 0.25. It revealed that the both of Papasan is closely relatedand belongs to the same species of Coccinia grandis L. Character differences between bothof Papasan only revealed physiology adaptation.Keywords: Coccinia grandis L., Papasan, Chromosome, Karyotype.Kata kunci: Coccinia grandis L., Papasan., Cromosom, Kariotype.

Abstract

Thirteen plant species of main vegetation alliances were detected upon their preferences on various abiotic factors,among them, six species had preferences on either soil or topographical factors, while four species only had preferenceson soil factors, and one species only on topographical ones. On topographical factors, there were six specieshad preferences most on average elevation and one species on minimum elevation of the research plots.Keywords : dominant plant species, ecological preferences, Mount Endut

Abstract

Mount Salak in West Java has important position as water catcment area of water, rain forest, and bank of biodiversity. To protect and conserve this area, Indonesian goverment through the Forest Department develop has Mount Salak to be National Park. Local people who live surrounding Mount Salak have local wisdoms about the benefit of plant and local perspective to manage biodiversity. For local people, Mount Salak is not only to their daily needs but also to save their history and legend about their ancestor. To collect data, we conducted indepth interview with local peple, observed and involved with their ritual local people of Mount Salak have ritual tradition and local belief about Mount Salak, that keep Mount Salak area protected and conserved sustainability.Keywords: Biodiversity, Gunung Salak, Kepercayaan Lokal, Konservasi, Upacara tradisi,

Abstract

The biodiversity conservation areas of Cirebon quarry, in this case Blindis and Sari mountains is a limestone ecosystem.Limestone ecosystems play an important role in climate regulation. Quantifying the organic carbon storage of limestoneecosystems in this area definitely helps to evaluate the roles of these ecosystems in both global and regional carbon cyclesand also their impact on climate. This research was carried out to know the complete data of carbon storage in Cirebonquarry on each ecosystem types. In deep, it will give information which ecosystem and carbon pool that contributes thehighest carbon stock. The carbon stock calculating methods in above-ground was based on RaCSA (Rapid Carbon StockAppraisal) methods. Based on the observation, there are three ecosystem types in Cirebon Quarry i.e. Opened Area, ThickBushes and Secondary Forest. The result showed that Secondary forest had the highest total C-stock which was 87.18 t Cha-1, while the C-stock on Thick Bushes and Opened Area were 42.95 and 17.92 respectively. The total C stock inbiodiversity conservation area of Cirebon Quarry was 148.05 t C ha-1 comprises 48% of C plant biomass and 52% of Csoil.Key words: carbon stock, Cirebon quarry, limestone area

Abstract

The presence of invasive alien plant species has been known to cause various negative impacts on ecosystems in theinvaded conservation area. This research aims to identify diversity and distribution pattern of invasive alien plantsspecies in Sempu Island Nature Reserve, and to determine the most influential environmental factors to theirdispersion. The methods used were the combination of quantitative vegetation analysis and rapid assessmenttechnique followed by the principal component analysis. As many as 10 invasive alien plants species (belonging to 7families) have been identified within this conservation area, e.g., Pistia stratoites, Ageratum mexicanum, Vernoniacinerea, Cyperus rotundus, Passiflora foetida, Centotheca lappacea, Eleusine indica, Imperata cylindrica, Hedyotiscorymbosa, and Lantana camara. All invasive alien plant species found in the sampling plots had a clumpeddistribution pattern. The most influential environmental factors to the invasive alien plants dispersion were landslope and distance from shoreline.Keywords: distribution pattern, environmental factors, invasive alien plants, Sempu Island Nature Reserve

Abstract

ABSTRACTVegetation Analysis of Natural Forest in Ternate Island, North Maluku. A vegetation analysisof the Ternate natural forest has been conducted by establishing 9 plots of each 30-m x 30-m.All trees (dbh. e”10 cm) within all plots were measured, their positions were determined, andtheir species were identified. In total there were 68 tree species recorded within plots belongingto 34 families. Trichospermum morotainense was the most common species, followed byAlbizia falcataria, Elmerilla ovata, Cordia mixa, and Macaranga longicaudatum. Almost allof the common species such as A. falcataria, Tristiopsis canarioides, Pometia pinnata, E.ovata and Intsia bijuga were found as emergent or canopy trees. According to the ordination(DCCA) analysis there were at least three tree species associations which were related tohabitat characteristics (conditions). However the population’s dominant species varied amongsites, which might be related to the habitat characteristics and/or effects of human activities inthe past.Keywords: Vegetation, natural forest, Ternate, North Maluku

Abstract

ABSTRACTNitrogen based fertilizers such as urea and NPK are primary needs for rice farmers. To get significant improvement of crop yield, the more quantity of fertilizers are applied. It make negative impact for surrounding environment. Based on that, the efforts should be done to suppress the demand of fertilizers such as by developing Nitrogen Use Efficiency crops. CsNitr1-L is one of gene that related to Nitrogen Use Efficiency trait in plant. The objectives of this research are to develop the construction of CsNitr1-L gene candidate in pCAMBIA1300-Ubi1 promoter and to obtain the transformants of rice cultivar Nipponbare which contain the construction of CsNitr1-L gene candidate. The construction of pCAMBIA1300::Ubi1::CsNitr1-L has successfully assembled and was transformed to immature embryo of rice cultivar Nipponbare using Agrobacterium tumefaciens strain LBA4404. It was obtained 146 lines of T0 Nipponbare. PCR analysis of T0 Nipponbare lines showed that 66 of them was identified as positive T0 lines contained hptII and CsNitr1-L genes. Transformation efficiency obtained was 11,9%. The result of analysis copy number using Southern Hybridization in positive PCR of T0 lines randomly indicated that 4 lines have a single copy of transgene. Based on these results, it can be concluded that CsNitr1-L gene construct was successfully introduced into the genome of the rice plant cultivar Nipponbare and the positive PCR of T0 lines containing the gene of hptII and CsNitr1-L, also a single copy of the transgene was obtained.Keywords: Nitrogen use efficiency trait, gene construction, rice kultivar Nipponbare
