Abstract

ABSTRACTMammalian Diversity Based on Altitudinal Range at Gunung Ciremai NationalPark. Gunung Ciremai was declared as national park in 2004. As a new national park,the mammalian data is lacking especially about mammalian diversity based on vegetationcomposition and altitudinal in Gunung Ciremai. The observation was conducted in 4habitats, such as: pine forest, lowland forest, mountain forest and subalpine forest elevationfrom 500 to 3078 m asl. Number of species found are 9 (7 species was through directobservation and 2 specis by indirect observation). Species richness index is 1,04; speciesdiversity index is 1,00 and species evennes index is 0,52. Relationship between mammaliandiversity and vegetation composition, that is sapling density, poles density and tree densityshowing significant value just for sapling density (r2= 0,501 dan p= 0,044). Relationshipbetween mammalian diversity and altitudinal show significant value (r2= 0,881 and P=0,025).Key words: mammalian diversity, habitat, vegetation composition and altitudinal

Abstract

ABSTRACTCharacterization of Lignite Biosolubilization Products by Indigenous Moulds from Soil ofCoal Mining in South Sumatera. Biosolubilization of coal is a potential technology of convertingsolid coal to liquid fuel and chemicals at ambient condition. Our previous research hassuccessfully isolated four moulds from soil at coal mining - South Sumatera and has potency aslignite biosolubilization agent, i.e. T1, T2, T4, T5. The objective of this research was to characterizeof lignite biosolubilization products by four isolates. The method used was sub-mergedculture. Cultivation medium was MSS+ (minimal salt + sucrose 0,1% + yeast extract 0,01% +lignite 5 %). Incubation was conducted at room temperature for 28 days. The result showed thatall indigenos moulds have different ability in lignite biosolubilization. The highestbiosolubilization occurred after 7 days of incubation belonging to T1 isolate. However, GC-MSanalysis showed the largest percentage of hydrocarbon compound which equivalent to gasolineand diesel was T5 after 7 days of incubation.Key words: Biosolubilization, lignite, moulds, coal.

Abstract

ABSTRACTLand Use Model of Moti Island, Ternate, Moluccas: A Vegetation Based Spatial Design Analysis.The Moti Island was dominated by mountain areas and humitropepts soil type which havehigh organic matter and low subsoil base saturated values. Geologically, it is a volcanic rockwith andesite composition includes lava, breccias and tuffs volcanic. Combined with highrainfall, width of island (24.6 km2) and very steep mountain (950 m asl.) the island has becomefragile when not well managed. Compared to the other district, the productivity of this area waslow because the natural resources have not been well developed yet. The shortage ofbiodiversity data of Moti Island has become major obstacles in developing Moti Island. Thisresearch was conducted to develop land use models as basic knowledge for spatial designanalyses of Moti Island. Detail discussion on developing Digital Elevation Model of land useand slope area based on vegetation data was presented in this paper.Key words: Moti, land use, digital elevation model (DEM), spatial designing analyses

Abstract

Family Pteropodidae known as fruit bats which has ecological services as seed dispersers, pollinator, and plays important role in the forest regeneration. Identification of bat species frequently encountered problems, i.e.,  criptic morphology and behaviour. Therefore it is necessary to confirm its identity using DNA barcodes. Cytochrome c oxidase subunit I (COI) mitochondrial DNA is representative of the protein coding mitochondrial DNA and has been used extensively as a means of animal species identification. This study evaluated 141 specimens consist of 42 species and 17 genera which were collected from Java, Nusa Tenggara, Sumatra, Kalimantan, Sulawesi, Maluku, and Papua. Phylogenetic analysis using the neighbor-joining method, in which the genetic distance matrix calculation by Kimura-2 parameter models are implemented on the pairwise distance calculation in the program MEGA version 6:05. The results of the analysis showed variation intraspecific ranging from 0 to 7.9% (0.9 ±0.014%) and there were 4 species with very high intraspecific average sequence divergence, i.e., Penthetor lucasi (3.2%), Thoopterus nigrescens (3.7%), and Chironax melanocephalus (8.7 %). Average interspecific of genetic distance  of fruit bats in Indonesia was 20% (1.3-26.1%). These results produce a phylogeny tree construction to form a clearly different cohesive cluster, except in the genus Dobsonia ( D. moluccensis, D. viridis, and D. crenulata), Cynopterus (C. brachyotis C. minutus, and C. luzoniensis), and Macroglossus (M. minimus and M. sobrinus ), because this did not correspond with currently recognized species boundaries based on morphology. Keywords: DNA barcoding, COI, Pteropodidae

Abstract

ABSTRACTTaro (Colocasia esculenta (L.) Schot.) has been cultivated for a long time in Indonesia. Taro tuber can be used as alternative food for rice substitute to support food diversification program. Taro cv. Bentul is preferable to farmers because it has few buds that are easy to maintain and adaptable in both lowlands and highlands. Its tuber has a delicious taste and a soft texture. Somatic cell manipulation of Indonesian taro through biotechnology may contribute to increase its productivity. One of in vitro technique for somatic cell manipulation is polyploidy. Oryzalin has been able to obtain taro cv. Bentul tetraploid. A total of 17 tetraploid clones were used in this study for clustering. Those clones were obtained from previous research and have stable ploidy level. The objective of this study was to determine cluster Bentul tetraploid of shoot culture using Ward method based on their in vitro growth as an initial selection before further selection in the field. Shoot tips of tetraploid were cultured on MS medium containing 2 mg/l BAP, 1 mg/l thiamine and 2 mg/l adenine for 6 weeks. The observed growth variables were number of shoots, length of petiole, number of leaves and roots. The clusterring was done using Ward and Euclidean Distance method followed by Analysis of Varians and Duncan Multiple Range Tests (DMRT). Out of 17 clones observed resulted in 3 clusters. Cluster 1 consisted of 2 clones, cluster 2 consisted of 9 clones, and cluster 3 consisted of 6 clones respectively. The best cluster was cluster 3 which was significantly different on the average number of shoots and leaves. Cluster 3 was dominated by clones derived from oryzalin at 75 ?M.Keywords: taro (Colocasia esculenta (L.) Schot.), tetraploid, in vitro growth, cluster analysis, Ward

Abstract

ABSTRACTDistribution Pattern of Butterflies on Various Ecosystem at Mt. Ciremai. To know the effectof ecosystem type on distribution pattern of butterflies in Ciremai mountain, we comparedbutterfly fauna between urban area (perkampungan), secondary and primary forest from 1000m asl to 1700 m asl., located in Apuy and Linggarjati tracks. During our study in Apuy (4 – 22April 2006) and Linggarjati (15 May– 4 June 2007) we recognized 66 species within 7 groups.Four groups distributed in specific habitats such as (1) perkampungan (Argomukti vilage,Apuy, 1000-1200 m.asl.), (2) secondary forest (Legok Pasang, Apuy, 1500-1600 m.asl.), (3)outsite forest Linggarjati, 800-1100 m.asl. (4) Linggarjati forest edge at 1100-1400 m asl. Theothers groups are butterflies that only distributed in Linggarjati or Apuy. Microclimate duringour study as well as weather condition at the time such as cloud, wind and rain impact theactivity of butterfly species and reflected to the species collected. Although the researchconducted in the same season (wet season) but Apuy and Linggarjati have differentmicrohabitats that caused some species are only found at Apuy or Linggarjati areas.Key words: Ciremai, butterfly, distribution

Abstract

Keanekaragaman Mamalia Kecil di Resor Kawah Ratu, Gunung Salak, Jawa Barat, Indonesia. Dalam rangka inventarisasi sumber daya hayati, telah dilakukan penelitian keanekaragaman mamalia kecil di kawasan Resor Kawah Ratu, Gunung Salak, Jawa Barat. Tujuan dari penelitian ini adalah untuk mengungkapkan jenis-jenis hewan mamalia kecil yang dapat dipakai sebagai masukan dalam rangka pengelolaan kawasan konservasi ini. Penelitian ini dilakukan dengan cara penangkapan menggunakan perangkap dan jaring kabut, serta observasi langsung pada tiga habitat utama yaitu hutan primer, hutan sekunder dan kawasan yang terganggu. Pengamatanpada masing-masing habitat dilakukan selama 4 hari. Sebanyak 60 perangkap kawat dan 20 ember jebakan sumuran digunakan untuk menginventarisasi hewan mamalia kecil darat. Empat buah jaring kabut digunakan untuk mengamati mamalia yang bergerak melalui udara. Dalam survei ini berhasil didokumentasikan sebanyak 179 ekor mamalia kecil yang terdiri dari 14 jenis. Hasil penelitian ini menunjukkan bahwa hutan primer mempunyai komponen penyusunkomunitas mamalia kecil yang berbeda dari kawasan terganggu dan hutan sekunder. Sedangkan habitat dengan tingkat keanekaragaman tinggi dijumpai pada kawasan terganggu dan hutan sekunder. Hal ini diduga karena kedua habitat ini menyediakan variasi pakan yang lebih beragam dibanding hutan primer.Kata kunci: keanekaragaman, mamalia kecil, hutan, kawasan terganggu
