Abstract

Long-tailed macaque (Macaca fascicularis) are one of the primates that are quite widespread in Indonesia, one of its in the area of Teluk Akar Bergantung city forest on Ketapang, West Kalimantan. This study aims to obtain data on the number of groups, number of individuals, population density, and structure of long-tailed macaque populations in the region using the line transects method and concentration count method. At the 95% confidence interval, the number of individuals ranged from -1,38 ind/ha to 30,20 ind/ha and the number of groups ranged from 0,72 groups/ha to 2,70 groups/ha. Population individual densities ranged from -0,39 ind/ha to 8,83 ind/ha and population group densities ranged from 0,21 groups/ha to 0,79 groups/ha. Structure of long-tailed macaque in the area of Teluk Akar Bergantung city forest on Ketapang, consists of 7,67 individuals of adult male, 9 individuals of adult female, 23,67 individuals of adolescent and 1,33 individual of children. Factors that affect the stability of long-tailed macaque populations include environmental conditions, types of feed, movement, interaction with other animals and the presence of predators.Keywords: Long-tailed macaque, population density, population structure, Teluk Akar Bergantung city forest.

Abstract

Riparian vegetation is a natural resource that is easily distrubed due to stabilization by human’s hand in ordinary rivers or within the scope of conservation areas  such as botanical gardens. Riparian vegetation plays an important role in maintaining the ecosystem stability of river, where the endemic wild animals are and maintaining the quality of sorrounding water. The purpose of this research is to analyze the stucture and compositio of dominant kinds and species of tree vegetation in riparian based Sambas Botanical Garden, Sabung village, Sabuh Sambas district, West Kalimantan. The method used in this study is survey with the combination of plant lanes technique , the spaces between two rows pf plants, and a line method. Observation tracks are made and placed in front of the vegetation. The placement  of the observation line is purposely set to present the middle, upstream and downstream river areas on the river bank of ±105 Ha. To analyze the area, the observation line was made about 6 lanes, with the lenght of each path was adjusted to the tide level approaching the land based on the existing hydrological cycle map to obtain 6 lanes with different lenghts.  For each of these lines a 20m x 20 m observation plot was made for tree level observation, 10m x 10m for pole observation, 5m x 5m for observation of piles, and 2m x 2m for observation of plant seeding rates. The process of seeding vegetation structure in riparian botanical garden was found complete from seedling, sapling, and poles to trees. The composition of riparian forest vegetation species consist of  22 species of vegetation, 14 families, and 18 genera with diversity for each low growth rate of less than 1, with pattern of spreading concentration and not concerntrated in one particular species. Therefor, with the discovery of the Hibiscus tilliaceus species at all growth rates, this species can be regarded as an indicator of ecosystems as a riparian forest ecosystem in Sambas Botanical Garden.Keyword : Diversity, Ecological Function, Hibiscus tilliaceus, Riparian

Abstract

The forest is a collection of plants dominated by trees with woody vegetation and other vegetation (Arif, 1994). In the absence of replanting or rejuvenation will threaten forest sustainability. The objective of the study was to assess the ecology and potential of nyatoh trees. Provided information on the ecology and potential of nyatoh trees in secondary forest areas. This research was conducted by survey method, the technique of placing the sample was a combination of path and plot line. Each path was placed systematically. The width of the line was 20 m, 750 m long with 7 observation lines. In this path, the measurement of seedling, stake, pole, and tree were done. The result of data analysis in secondary forestwere 46 tree species at all growth level, from 46 species of tree there were 2 species of nyatoh tree ie nyatoh klincir (Palaquium rostratum) and nyatoh sangai (Palaquium obtusifolium). The dominant plant species for seedlings, stakes, poles and trees were wood with the value of INP respectively 16,18%, 24,74%, 25,26% and 28,26%. Types strongly associated with nyatoh include Mentibu (Dactylocladus stenostachys Oliv) with Ochiai index 0.51, followed by Change (Eugenia sp) with index of 0.49, Tekam (Hopea dasyphyla V.SI) with index of 0.49.Keywords: Palaquium spp, Nyatoh Ecology, Nyatoh Potential, Secondary Forest
