PERILAKU MAKAN DAN JENIS PAKAN ORANGUTAN (Pongo pygmaeus) DI HUTAN DESA GURUNG MALI KECAMATAN TEMPUNAK KABUPATEN SINTANG
Get PDFThe condition of orangutan habitat in ex-situ conservation areas is different from the condition of their natural habitat. These different habitat conditions will have an impact on orangutan behavior, especially food behavior and selection of feed types. This study aims to determine the feeding behavior and the food types of orangutans (Pongo pygmaeus) in the Forest Of Gurung Mali Village Tempunak Sub-district Sintang District. Observation of eating behavior is done using the focal animal sampling method. Observation of eating activities is quantitative, namely recording the time taken during orangutan eating activities. Observation of the type of feed is done by observing the remnants of discarded plants found on the forest floor and trees found as a place for orangutans looking for food sources. Based on observations of the eating behavior of each individual orangutan for the food provided shows the behavior of eating while sitting is higher than the percentage of other eating behavior. For the eating behavior that they are looking for themselves, it shows that Oscar, Digo and Putri tanjung individuals have higher hanging behavior compared to other eating behaviors. The percentage of Momo and Jojo individuals sat higher eating behavior compared to the percentage of other eating behaviors. The types of feed found in the study site were found 8 types of feed provided by the Rehabilitation center and 24 types of natural food contained in the enclosure forest.Keywords : Feeding Behavior, Orangutan, Type of Feed
STUDI PERBANDINGAN PENGUKURAN BIOMASSA POHON MERANTI (Shorea spp.) DENGAN MENGGUNAKAN ALAT MANUAL, MEKANIS DAN DIGITAL DI KAWASAN ARBORETUM SYLVA INDONESIA PC. UNTAN
Get PDFUntan Biomassa Karbon Meter (UBKM) is one of the tools developed to accommodate the needs of carbon biomass measurements with non-destructive methods on standing trees. The study aimed to compare the results of biomass measurement by Manual (Phiband), Mechanical and Digital. The research was conducted for two weeks in September 2017 using exploration method, census data retrieval technique. The results of the study in the Arboretum Sylva Indonesia PC. UNTAN there are 10 types of Meranti (Shorea spp.) Among others Shorea balangeran, Shorea beccariana, Shorea bracteolata, Shorea havilandii, Shorea hopeifolia, Shorea leprosula, Shorea macrophylla, Shorea ovalis, Shorea palembanica and Shorea seminis. With the total number of 39 individual trees and carbon biomass measurements have been done using Phiband, UBKM Mechanical and UBKM Digital. In the measurement using Phiband obtained total biomass 24.405,42 (kg) and carbon 11,470,55 (kg), UBKM Mechanical obtained total biomass 23,665 (kg) and carbon 11,122,55 (kg) and UBKM Digital obtained total biomass 25,070,81 (kg ) and carbon 11,783.28 (kg). Based on comparison result of biomass measurement between Phiband with UBKM Mechanical obtained difference of 3.03% Phiband with UBKM Digital obtained difference of -2,73% and UBKM Mechanical with UBKM Digital obtained difference of -5,94%. Biomass measurements using Phiband become parameters of UBKM Mechanical and UBKM Digital tool on the measurement of Meranti tree biomass (Shorea spp.). Measurement of biomass using UBKM Mechanical gets lower value (under estimate) from biomass measurement using Phiband tool. While biomass measurement using UBKM Digital get higher value (over estimate) from biomass measurement using Phiband tool.Keywords: Biomass, Digital, Manual, Mechanical, Merant

STRUKTUR DAN KOMPOSISI JENIS VEGETASI RIPARIAN KEBUN RAYA SAMBAS KABUPATEN SAMBAS KALIMANTAN BARAT
Get PDFRiparian 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, Riparia

Get PDFPeatland is the result of organic matter accumulation from the decaying vegetation with naturally occuring through long term decomposition processes. The purpose of this study was to gain the information about the effect of water table level on some peatland chemical and physical properties of Kuala Dua village, Kubu Raya regency. The method used in this study was experiment al study the soil samples on 3 (three) water table levels were while examinated. Experimental study with completely randomized design using soil sampels of three water table levels 30 cm, 50 cm, and 80 cm with three replication. The result of this study showed that the depth 0-40 cm of water table level had the range values of soil water contents (397,3-460,5%), soil bulk density (0,18-0,25g/cm3), cation exchange capacity (116,4-118,4 mEq), soil organic carbon (56,8-57,5%), nitrogen (1,89-1,91%), soil phosporus (38,84-267,17%), soil humidity (8,2-9,9 %RH), soil potential hydrogen (3,04-3,17) and soil temperature (27,3-29,3˚C). Base on the results, soil temperature and soil humidity were effected by peatland water table level, while the others properties were not impacted.Keywords : chemical properties, peatland, peatland managemen, physical propertie

Get PDFAnts (Formicidae) are a type of insect that has a fairly stable population throughout the season and year. Its large and stable amount makes ants one of the important insect colonies in the ecosystem. Ants are often used as bio-indicators in environmental assessment programs. This study aims to record the diversity of ant species (Formicidae) in secondary natural forest areas in Sepandan Village, Batang Lupar District, Kapuas Hulu District based on altitude from sea level. The method used is purposive sampling by using a trap in each tree in the path of observation, this observation uses three paths based on the height of the observation place, the first line at an altitude of 100 meters above sea level, the second track at an altitude of 200 meters above sea level and the third line at an altitude of 300 meters above sea level. The trap used is Pit Fall Traps trap on the ground surface and Fly Sheet on the tree. Ants who were captured at an altitude of 100 masl were 1,025 individuals consisting of 9 genera and 13 species, at an altitude of 200 masl of ants that were successfully captured as many as 4,228 individuals consisting of 8 genera and 9 species, while at an altitude of 300 masl ants were captured as much as 2,940 individuals consisting of 15 genera and 21 species. The dominant species at an altitude of 100 meters above sea level is Crematogaster obscura, at an altitude of 200 meters above sea level dominated by the species Crematogaster reticulata, and at an altitude of 300 meters above sea level this location is dominated by Acanthomyrmex ferox species. Diversity index of ant species at an altitude of 100 masl of 0.709, at an altitude of 200 meters above sea level of 0.565 and at an altitude of 300 meters above sea level of 1.131 with a total diversity value of 0.801.Keyword: Ant, Diversity, Secondary Natural Forest
