Abstract

ABSTRACTA Forest ecology research has been done in Batangtoru watershed, North Sumatra to determine the species composition and vegetation structure. The study was conducted by using plots in four locations: Purnama,Gerhana, Kejora, and Teluk Nauli. A total of 387 species in 184 genera and 77 families were found. The species richness of trees (dbh >10 cm) was 192 species in 116 genera and 55 families, the richness of saplings(dbh 2 - 10 cm) was 211 species in 111 genera and 55 families, while the richness of seedlings (dbh <2 cm) was 153 species in 95 genera and 50 families. Tree density ranged from 850–1,700 individuals/ ha, while basalarea was around 66.76 to 104.54 m2/ha. The forest canopy at Purnama and Gerhana plots was relatively similar, forming three layers, while the Kejora and Teluk Nauli plots were simpler with only two canopy layers. Basedon a principal components analysis of tree species, the forests in the research area tended to form three community types: 1) forest dominated by Pentaphylacaceae, 2) mixed dipterocarp forest, and 3) forest garden,or natural forest communities enriched with a variety of economically valuable forest tree species and therefore classified as an agroforestry system.Keywords : Floristic, structure, forest community type, Batangtoru watershed, North Sumatra

Abstract

ABSTRACTSeagrass ecosystem has a function of spawning, nursery, and feeding ground. Besides, it could be used as a bio-indicator of environmental health. This study of seagrass ecosystem was done in 17- 22 May 2014 in Lembeh Island and Tanjung Merah, Bitung. The purpose of the study is to obtain existing condition of seagrass ecosystem and its role as environment bio-indicator. Purposive sampling method was used representing all study sites. Structure analysis of seagrass communities describes the existing condition, while scoring / weighting method estimate current condition of the seagrass. Results that show there are seven species of seagrass. In the stations opposite to Bitung mainland, 75% of the seagrass are Enhalus acoroides (10-50% covers). Importance value index of the seagrass species were Enhalus acoroides (231–300 %), Thalassia hemprichii ( 102–198 %) and Halophila ovalis (110 %) respectively. Based on the weighting method and environmental standard quality, seagrass ecosystem in Lembeh island opposite to Bitung mainland was in damage and unhealthy condition, while seagrass ecosystem opposite to the open sea was in a good and healthy condition. This was due to the domestic waste that is trapped in seagrass ecosystem in the study site. It is necessary to improve awareness to maintain quality of environmental.  Keywords: seagrass, existing, bioindicator, Lembeh Island

Abstract

ABSTRACTThe Exploitation Rate of Endemic Bonti-bonti (Paratherina striata) in Towuti Lake. Bonti-bonti(Paratherina striata) is an endemic fish species as vulnerable species to extinction. This fish livein Towuti and Mahalona Lake the tectonic-oligotrophic lakes that are located in Malili Complex,South Sulawesi. This lake is used for various purposes i.e. hydroelectric power plant, capturefishery, navigation, ecotourism and source of water for domestic uses. This lake also supports lifeof endemic fish species that should be protected from decreasing population due to intensiveexploitation. The objective of this research was to study the exploitation rate of Bonti-bonti asconservation efforts. The study was done in Towuti Lake from May 2006 to April 2007 usingdescriptive method. Utilization rate of Bonti-bonti stocks in Towuti Lake indicated an overfishingcondition of male and female population. Increasing effort (units/month) of dipnet tends to reducefishing gear productivity.Key words: exploitation rate, Bonti-bonti, endemic fish and Towuti Lake

Abstract

ABSTRACTThe Effectiveness of Rhizospheric Bacteria Mix Inoculant Associated with Maizein Latosol Lampuog Soil. Two greenhouse experiments were carried out to evaluate theeffectiveness of Plant Growth Promoting Rhizobacteria (PGPR) ino-culants on plant growthof maize. In the first experiments, eleven single isolates were screened for associationeffectiveness with maize. Inoculation improved plant perfomance by increasing roots, shootsand total plant dry weight. Five isolates with the increase of plant dry weight ranging from 27-47% over control were then selected for mixed inoculants. In the second experiment, tenmixed inoculants consisted of 3 single isolates were evaluated on plant growth, N plant yield,and N derived from fertilizer and contribution from fixation. The later parameter was.determined by "N method. Three mixed inoculants namely M5, M8, and M9 showed highereffectiveness with the increase of plant weight 27-29% over control. Plant N yield of plantsinoculated with those mixed inoculants were 176-194 mg N/pot as compared to 144 mg Nlpotin control plants. Lower %eIx cess atom % in inoculated plants indicated some Ncontribution from fixation which ranged from 1 5 -2 1 %.Key words : mixed inoculants, % method, maize, latosol

Abstract

Slow lories is small size primates of the genus Nycticebus that are in endangered status. Habitat pressure andhigh trade as pet animals has made the population decline both quantitatively and qualitatively, therefore it isnecessary to save the slow lories through conservation action. Morphologically, the individuals are difficult tobe distinguished among the species, therefore making much harder in identification for conservation purposessuch as from confiscated individuals. Therefore molecular marker is needed through mitochondrial DNA usingCOI gene sequences analysis is needed for identification. This study used 24 samples of slow lories consistedof 2 from Kalimantan, 9 from Java and 13 from Sumatra. The result indicated that in the 660 bp there were 62variable sites with 15 haplotypes: 4 haplotypes of N. javanicus, 9 haplotypes N. coucang, and 2 haplotypes N.menagensis. Base on nucleotide variations at specific sites, it was formed haplotype differences among species.The average genetic distance between species showed that Kalimanatan population were closer to thepopulation of Sumatra (d= 0.042 ± 0.006) compared with Java population (d= 0.059 ± 0.009), whereas thegenetic distance within population showed the population of Java had low diversity (d= 0.002) with a meannucleotide differences 2.6. Thus Jawan slow loris (N. javanicus) should be conserved.Keywords: Nycticebus spp., molecular, COI, conservation, marker
