KEANEKARAGAMAN JENIS GASTROPODA DI HUTAN MANGROVE SUNGAI KAKAP KABUPATEN KUBU RAYA
Get PDFGastropod is one of the mollusk phylum that can adapt and decompose in mangrove forests. The mangrove forest in Sungai Kakap is an area that is slowly being opened due to the local community people’s activities. They opened land to build buildings, farms, and villages. This research is aimed at studying the diversity of Gastropod and the influence of the mangrove tree density on the gastropod diversity in the mangrove forest of Sungai Kakap, Sungai Kakap Village of Kubu Raya Regency. The data were taken in May 2018. The analysis was conducted using the observation method by making six observation lines. The lines were differentiated based on the density of the vegetations: dense, medium, and sparse. The number of Gastropods found in the Kakap River mangrove forest is 4 types of gastropods with a total of 252 individuals. Respectively from dense, medium, and sparse vegetation, the gastropod dominance index is 0.68, 0.37, and 0.51; the diversity index is 0.25, 0.49, and 0.33; the species average index is 0.27, 0.97, and 0.4; and the gastropod species richness index is 4.03, 1.18, and 0.7. Lastly, the species similarity index is respectively 86%, 66%, and 86%. Keywords: Gastropod, Mangrove Forests, Vegetation density

DAYA HAMBAT EKSTRAK KULIT JATI (Tectona grandis Linn F) TERHADAP PERTUMBUHAN JAMUR PELAPUK KAYU Schizophyllum commune Fries
Get PDFThe aim of the research was to examine the antifungal activity and the most effective concentration of teak bark (Tectona grandis Linn F) extract in inhibiting wood decay fungi Schizophyllum commune Fries. Teak bark was derived from BKPH Ledok, Sambong district, Blora Regency, West Java. The Teak bark made into particle with size pass of 40 mesh and retained 60 mesh. Then one kilogram of teak bark particle was maceration with 10 liter of aquadest. The extract then mixes with potatoes dextrose agar (PDA) with several concentration i.e. 0%, 0.25%, 0.5%, 0.75% and 1% and pour into petri dish. One isolate of Schizophyllum commune was put in the center of PDA in each petri dish then incubated for nine days. The bioactive compound of extract teak bark was evaluation used phytochemical screening. Result of the research showed that teak bark extract at concentration 0.25% and 0.5% has antifungal activity values was 27.98% and 40.38% and categorized as medium inhibition growth of S. commune. Meanwhile at concentration 0.75% and 1% the AFA values was 59.94% and 65.51% categorized as strong inhibition growth of S. commune. The bioactive compounds from phytochemical screening test were alkaloid, flavonoid, terpenoid, fenolik, antrakuinon, and saponin. The extract of teak bark with concentration 0.75% and 1% are the most effective concentrations in inhibiting the growth of wood decay fungi S. commune Fries.Keywords : antifungal, phytochemical screening test, Schizophyllum commune, Tectona grandi
KETERBUKAAN TAJUK AKIBAT KEGIATAN PEMANENAN DENGAN TEKNIK REDUCED IMPACT LOGGING DALAM PENGELOLAAN HUTAN ALAM (Studi Kasus Pada Petak Tebangan L37 RKT 2015 IUPHHK–HA PT. Batasan Camp Tontang)
Get PDFTropical rainforests have very important functions such as hydrological functions, ecology, economic and social. However, the existence of forest harvesting activities potentially decrease the function. Implementation of poor forest management, causing damages resulting from harvesting processes such as canopy exposure, areal exposure and damage to residual stands. Based on the description it is necessary to do research on the analysis of canopy exposure in natural rain forest area IUPHHK-HA PT. Batasan Camp Tontang. This study aims to determine the extent of canopy exposure due to harvesting activities and to know the relationship between the width of the basic fields of cut down trees per hectare to the exposure of the canopy. This research was conducted on the 2015 RKT and in IUPHHK-HA area of PT.Batasan Camp Tontang,Nanga Serawai Sub-district, Sintang District, West Kalimantan Province. Canopy exposure as a result of harvesting activities is obtained by measuring its openness using a spiracle densiometer tool. The percentage of openness is then analyzed by the equation Y = a + bX, where Y is the percentage of canopy exposure whereas X is the base area of the harvested trees per hectare. To find out the real relationship between the width of the tree base area felled by the openness of the canopy, it is done with the F test and to know the close relationship between variables X with variable Y by closeness relationship test or r test. Timber potential before harvesting in 9 research plots with the tree level average value is 35.78 stems / ha. After harvesting activities, timber potential has decreased due to timber harvesting activities to be 9.33 stems / ha. The percentage of canopy exposure after harvesting activity was 49.35% and included in medium level of exposure. From the calculation results, the equation which is obtained by regression line of the relationship between the width of the base area of the trees cut down per hectare with the value of the canopy expose, shows that the greater tree cutting base area, the greater canopy exposure that occurs.Keyword: Canopy exposure, Degradation, Spiracle Densitometer

Get PDFRubber is a forestry plant producing sap. Rubber latex is needed for various industrial purposes. Rubber is a side business as well as additional income for the community besides farming in Banua Tengah Village. The method used is a survey method with interview techniques. Sampling was done intentionally (purposive sampling). The number of samples taken was 61 respondents who were ; rubber farmers, married, worked tapping rubber and owning rubber plantations. Data analysis consists of calculating total income and multiple linear regression analysis. The analysis results obtained total income / Tr received by farmers around Rp. 390,000 - Rp. 2,840,500 / month, when compared to the UMR established by the Government in 2018, UMR Kapuas Hulu Regency is Rp. 2,204,650.00 / month, there are 2 (two) farmers who have an income above the minimum wage while 59 other farmers are still under the UMR There are four factors that influence the income of rubber farmers in Desa Banua Tengah namely land area, work experience, rubber age and workdays, of the four most influential factors are land area and workday variables, while the work experience and rubber age variables are not very influential. Factors of land area, work experience, rubber age and working days together greatly affect farmers' incomes with the equation of total income of rubber farmers as follows: ln Y = 9,817 + 0,397 ln X1 + 0,098 ln X2 + 0,061 ln X3 + 1,194 ln X4 Correlation value R = 0.928 and the value of determination R2 = 0.861 From these equations obtained a constant value of 9,817 which shows that income from rubber farmers (Ŷ) in Desa Banua Tengah is Rp. 9,817 if X₁, X₂, X3 and X4 are considered zero. Ŷ is positively correlated with X₁, X₂, X3 and X4.Keywords: Influential factors, Latex, Rubber farmers, Total incom

KEANEKARAGAMAN JENIS KELELAWAR (Chiroptera) DI HUTAN KOTA TELUK AKAR BERGANTUNG KABUPATEN KETAPANG
Get PDFBats (Chiroptera) are the only mammals that can fly. Bat habitats are in caves, large trees in the forest, hollow trees, coconut trees, banana trees and roofs of buildings. Bats are nocturnal, they forage at night and sleep during the day by hanging upside down. Teluk Akar Bergantung has a generally flat and swampy topography, with a small portion submerged in water. Various types of trees have grown, one of them is Beringin/Kayu Are, which is where bats live. Bats play a role in the balance of ecosystems as seed dispersers, flower pollinators, insect controllers and guano producers. Based on the potential in this area, the research aims to collect data on various types of bats in Teluk Akar Bergantung, Ketapang regency, West Kalimantan. The method used is catch and release method using mist nest. Data analysis of the research used bats identification guide written by Suyanto (2001) entitled “Kelelawar di Indonesia” and “Panduan Lapangan Mamalia di Kalimantan, Sabah, Sarawak dan Brunei Darussalam” by Payne et. al (2000), diversity index (H’), equitability index (e), dominance index and species richness (d).
