Get PDFThe study aims to know the diversity of species nails in an secondary forest in regional IUPHHK-HTI PT. Bhatara Alam Lestari to Kabupaten Mempawah. The research is all sports of crops spike in research area. The study was conducted using a method of survey and the sample collection technique in do with or placement tenement sample in doing intentional. The size of tenement her observation is 20 X 20 m, section of the test the as much as to 2% (3,98 Ha) of the area in the ( 199,33 Ha) so there will a 10 tenement observation. the results of the study showed that kind of a nill cecerean INP the highest number with value of having the value of the (52,76), while value INP the lowest on the type of nails remiding worth INP (8,19), index value dominance (C) suggests that dominance not focused on a species in a row, but spread in between all tenement. So the index domination showed that the plants a spike on tenement observation not dominant, because it is still under the standard dominance (<1), and index value diversity (H) highest is spikes cecerean. To grow in a good in plants a nail is caused by temperatures and humidity of the air that shall and get a sunburn enough.Keywords: a nail cecerean, a nail nest of a bird, an terrestrial, Epiphyte, The diversity of specie

Get PDFMangrove forests are one of the ecosystems that have important values in terms of physical, biological and economic. Increasing the quality of forests can increase the usefull of one of the biological benefits. This can be seen by many animals that use the forest as a shelter, spawning, foraging and so forth. One of the mangrove forest in Sungai Bakau Kecil`s Village, Mempawah, West Kalimantan. The purpose of this study was to determine the effect of density and vegetation structure on the abundance of shellfish.The method used in this research was survey. Determination of starting point as the first line of observation was done purposively (placement deliberately), for the next path systematically with a distance of 100 m. Observation of mangrove vegetation was pathway technique. Each path was made of 3 plots of observation of mangrove vegetation and shellfish with each plot area of 10 m X 10 m. The plot was made perpendicular to the coastline, the first plot was near the beach then the second plot was made 50 m from the first plot and the third plot was made 50 m from the second plot. The samples was made of 3 quadran with 1m x 1m for shellfish samples .The highest density of vegetation with the highest shellfish was found in observation plots 3, 6 and 9 with each density of Vegetation in plot 3, 6, 9 were 7851/Ha, 13029/Ha and 5261/Ha respectively, and the range of 6-8 shellsfish.

SIFAT PAPAN PARTIKEL DARI CAMPURAN KULIT KAYU Rhizophora apiculata BI DAN Acacia crassicarpa A. Cunn. Ex.Benth BERDASARKAN KONSENTRASI PEREKAT UREA FORMALDEHIDA
Get PDFThe need of the Indonesian people to wood each year increases with the increase of population. This is not matched by the existing of wood supply, so that another alternative is needed to meet the wood demand by making wood composite such as particle board. The purpose of this research is to evaluate the effect of concentration UF adhesive, material composition and the interaction of both factors on physical and mechanical properties of particle board made from Rhizophora apiculata BI bark and Acacia crassicarpa A.Cunn.exBenth that meet the JIS A 5908-2003 type 8 standard. The materials used in this study are bark of mangrove, bark of acacia, urea formaldehyde adhesive, liquid paraffin and catalyst. Particle board were prepared with the composition of raw materials of bark of mangrove: bark of acacia were 100: 0, 50: 50, 0: 100 and adhesive concentration of 8%, 10%, 12%. Particle board was made with size of 30 cm x 30 cm x 1 cm with target density of 0,6 gr/cm3. Hot pressure was done for 10 minutes with a temperature of 120 oC and pressure of 20 kg/cm2. The results showed that the composition of the material had a significant effect on moisture content, thickness swelling, water absorption, internal bonding, MOR and MOE. The adhesive concentration factor significantly affected the thickness swelling, internal bonding, MOE and MOR. The interaction of both factors had only a significant effect on the screw hold strength, while there is no significant effect on the other physical and mechanical properties. The best physical and mechanical properties are generated by particle board with composition of bark of mangrove and bark of acacia (50:50) and 12% adhesive concentration.Keywords: adhesive concentration, bark of acacia, bark of mangrove, particle board, physical and mechanical properties

Get PDFThis study aims to assess and provide information on how big the dominance and association of trees in IUPHHK-HTI PT. Bhatara Alam Lestari area. The problem in this research is the existence of human activities in managing the forest excessively, the forest was converted to a lot of plantations and agricultural areas and the occurrence of illegal forest clearing, feared loss of forest vegetation in the area. The research method used was plotted path mixed method with the laying of the purposive sampling path, the observation variable was the entire growth rate of the seedling, stake, pole, and tree levels. Based on the results of research there were 51 species of trees, 7 species of which were trees that entered into the group of Kayu Indah. Based on the results of research conducted it could be concluded that the type of dado, embun, jungkang, kayu malam and ubah were the dominant vegetation type for seedling level. Type of embun, jungkang, kayu malam, medang, nyatoh and ubah were the dominant vegetation type for stake level. Type of dado, embun, jungkang, kempas, petai, rengas and ubah were the dominant vegetation type for pole level. Type of jungkang, kayu malam, medang, ubah were the dominant tree for tree level. While the Ochiai index of kayu malam species had a negative relationship to the 3 dominant tree species, because the value of the Ochiai index was closed to 0.Keywords: Association, Dominance, Kayu Indah, Secondary Forest
