ABSTRACT

Tree locations  and crown positions was assumed to have effects on adsorption of dust and Pb particles by leaves.  The objectives of the research were: (a) to determine the effects of tree locations and crown positions on adsorption of dust and Pb particles of leaves in roadside vegetation; (b) to determine the pattern of dust and Pb particle adsorption of leaves in roadside vegetation; (c) to determine correlation between dust and Pb concentration. Leaves samples was taken from the front and back part of the crown of three trees from each of the first three rows of the roadside vegetation.  The samples were used to analysis dust and Pb concentration.   The results showed that  tree locations and  crown positions  affected adsorption of dust and Pb concentration of leaves. There was no interaction between tree locations and crown positions, but there was a decreasing trend from front part of the crown of trees1 until back part of the crowns of tress3.  There was a correlation (R2= 0,755) between dust concentrations and Pb concentrations with equation of Y= 0,1403X-41,686 (Y= Pb concentration ; X= dust concentration).

KEANEKARAGAMAN BURUNG AIR DI BAGAN PERCUT, DELI SERDANG SUMATERA UTARA

ErniJumilawaty, AniMardiastuti, Lilik Budi PrasetyodanYeniAryatiMulyani

ABSTRACT

Mudflat in BaganPercut plays important role for many activities of waterbirds, i.e. feeding ground, shelter and many activities social. The aim of this research was to know waterbirds diversity. This research was found 33 species (5 families) of waterbirds that use mudflat in BaganPercut. The highest number of species (26 species) was found in October. The highest diversity (H’ = 2.59) was found in February and lowest (H’ = 1.50) in March. The value of evenness (Shannon index) was higher (0.84) in February and lowest (0.60) in March and October. Charadrius leschenaultia, C. mongolus were dominant species. This identification showed that two species Mycteriacinerea and Leptoptilosjavanicus were International protected species according to Vulnerable and two species Numeniusarquata and Limnodromussemipalmatus Near Threatened IUCN. Fifth teen species of them were protected in Indonesia.

KETERGANTUNGAN DAN KERENTANAN MASYARAKAT TERHADAP SUMBERDAYA DANAU: KASUS DANAU RAWA PENING

Partomo, SyafriMangkuprawira, Aida Vitalaya S. HubeisdanLukyAdrianto

ABSTRACT

RawaPening Lake is one kind of ecological systems that played an important social role for its surrounding community. Ecological function of the lake is about to be threaten by many pressure which is natural event as well as anthropogenic occurrence. This may lead to make lake as an ecological system susceptible to external disturbances. This research is intended to identify the degree of community dependency on lake resources and to investigate the extent of  vulnerability of surrounding RawaPening Lake community. Method employed in this research were descriptive analysis and vulnerability analysis. Research reveals that KecamatanTuntang and Ambarawa have high vulnerability, the condition in which the high potential threat may put on the track to the destruction of lake natural resources and environment.

Keywords: dependency, vulnerability, lake.

 

POLA AKSES PETANI PENGGARAP LAHAN DI KAWASAN PERLUASAN TAMAN NASIONAL GUNUNG GEDE PANGRANGO JAWA BARAT

ABSTRACT

Nature resource utilization by local peoples around the resource have been part of Indonesian culture, occuring at many places, for instance in expansion area of GunungGedePangrango National Park (TNGGP). Research was directed to describe the access pattern (way of getting access and access utilization forms) in frame on formulating model and strategy of restoration activities implementation. Research result shown that community access interrelated  with history of this area management and dependency of land user to forest resources that is influenced by land property factor, agronomic culture, and local institution; also shown that there are 2 (two) types of community  access goals i.e. non woody forest product harvesting and forest land using as agronomic activity that can be differenced  into 5 sub-types utilization forms base on kind of commodities (main food, horticulture, trees, Multi Purpose Tree specieses, and medicinal crop); 3 sub-tipes base on  time scale of commodities production (seasonal, annual, perenial); and 4 sub-tipes based on agronomic pattern (agronomic system base), i.e: vegetable base, rice-horticulture base, casava-banana base, and agroforestry. Finding 5 kind of access patterns of community to gain access on forest land i.e:  land distribution pattern, self-community inisiative pattern, inheritance pattern, compensation cost pattern, and pawning/rental pattern. Necessarily to formulate institution for ensuring restoration object and community access.

ANALISIS POPULASI OWA JAWA (HylobatesmolochAudebert 1797) DI KORIDOR TAMAN NASIONAL GUNUNG HALIMUN SALAK

Yumarni, HadiSukadiAlikodra, Lilik Budi PrasetyodanRineksoSoekmadi

ABSTRACT

Javan gibbon (HylobatesmolochAudebert 1797) is an endemic primate of Java Island, living only in West and Central Java. IUCN (International Union for Conservation of Nature) puts it in the list of endangered species. This studi aims at understanding the population of javan gibbon in GunungHalimunSalak National Park. This research have been done in GunungHalimunSalak National Park’s Corridor. It employs the line transect method.This study result 9 groups and 28 individuaals of javan gibbon in GunungHalimunSalak Corridor. The average group density for javan gibbon for the HalimunSalak National Park Corridor was 0,01-0,03 groups/km2, and population density was 0,04-0,09 individuals/km2.The distribution of groups javan gibbon in Sukagalih, Cilodor, GH, Cisarua, Ciherang, and Cipicung but not detection javan gibbon group in Cipanas. Groups composition of adult male and female, subadult, and infant.

PERILAKU TRENGGILING (Manisjavanica, Desmarest, 1822) DAN KEMUNGKINAN PENANGKARANNYA

BurhanuddinMasy’ud,  Novriyantidan M Bismark

ABSTRACT

Pangolin (Manisjavanica, Desmarest 1822) has believed by many peoples as  food and medicine who have a high economic value, so demand of pangolin tend increase. Wild harvesting  from natural habitat are  the way always  used to  supply of   demand,  and this was affecting to wild population has been decrease significantly. Captive breeding programs in the ex situ area is  the best alternative solution to support the demand sustainability and its conservastion in natural habitat. The question is, “ did success possibilities to captive breeding? Based on the study have been done about animal behaviour and implementation of some technical of captive breeding program,we would like to say that the captive breeing program of pangolin could be success.

Key words: pangolin, behaviour, daily activities, captive breeding

YantoSantosa, SupartonodanMachmudThohari

ABSTRACT

The isolation of habitat, shrinking of natural habitat and diminishing of habitat quality have increased conflicts between man and elephant to utilize space and abundance of food.  This research was carried out from April to June 2007 in Seblat Training Centre for Elephants. The objectives of this research were to recognize the potential of food plants for the elephants, the productivity of food plants, types and parts of food plants favoured by the elephants, and preferential of specific food plants and feeding behaviour. The analysis was conducted by means of vegetation analysis, through cutting and pruning parts of feeding plants, studying them and running statistical procedures to acquire conclusions about the food plant species.  The analysis was followed by observing the feeding behaviour of the elephants on foot. Ground plant species which were potential as elephants’ feed comprised of 36 species, 29 spesies at seedling level, 26 species at sapling level, 24 species at pole level and 29 species at tree level. The highest productivity for sapling and pole levels are Leeaindica and for seedling level is Gigantochloa cf. atroviolacea. The feeding plants of elephants comprises of 245 species from which 11 parts of the plants preferred by the elephants. Gigantochloa cf. atroviolacea and Stachyphryniumsp were the most favored plant species, indicated by the highest preferential index. The feeding behaviour of elephants could be categoried into 8 categories.

Keywords: Sumatran elephant, Seblat Training Center of Elephants, preferential, productivity.
