Get PDFThe utilization of non timber forest products that represent potential mangrove forests lack of consideration of various products and services that can be produced. Conversion of mangrove forest to other uses deemed more profitable than explored the potential. The purpose of research that was conducted in April-May 2013 were to calculate the total economic value of mangrove forest in Margasari village sub district of Labuhan Maringgai district of Lampung Timur. Respondents are 43 mangrove forest communities selected by purposive sampling. Data were collected by direct observation and interviews, the analyzed using the formula total economic value (TEV). The results showed the total economic value of mangrove forests of Rp 10.530.519.419,00 of year consisted by (1) direct use value of Rp 1.877.440.000,00 of year of utilization of fuel wood, leaves and mangrove fruit, (2) indirect use values of Rp 8.915.036.479,00 of year of natural food provider for the marine life, (3) option value of Rp 103.425.000,00 of year of biodiversity and (4) existence value of Rp 1.580.000,00 of year of society's willingness to pay
Identifikasi Jenis Epifit Dan Tumbuhan Yang Menjadi Penopangnya Di Blok Perlindungan Dalam Kawasan Taman Hutan Raya Wan Abdul Rachman
Get PDFEpiphytic is one among the plants that attaches and grows on other plants for sunlight, water, air, and minerals. The existence of epiphytes is very important for forest ecosystems due its ability to provide a place for the ants and the other organisme. The objective of this study were to identify the species of epiphytes, species of cantilever plant, and to know the number of cantilever plant species associated with the species of epiphytes in Wan Abdul Rahman Great Forest Park. This research was conducted at the protection block, Wan Abdul Rahman Great Forest Park, particularly in the area of Way Balau Sub-watershed. This research was conducted during September to October 2013. Epiphytes and cantilever plants species were inventoried in a sampling intensity of 0,2% taken from 796,50 ha of total area of protection blocks, therefore the large of sample plot is 1,593 ha. The size of each sample plot is 400 m2 or 20 m x 20 m, therefore the total number of sample plots are 40 plots. Observed variables were the species and the number of epiphytes , species of cantilever plant and its number, and the importance alue index for each species. The result of the study showed that plant are 7 species of epiphytes and 16 species of cantilever plant. The highest importance value index (IVI) of epiphytes is paku sepat (59,14%). The highest IVI of cantilever plant is pulai (30,91%). The most abundant cantilever plant growed by epiphytes is pulai (Alstonia scholaris), pinangsi (Villebrunea rubescens), enau (Arenga pinnata), and medang gabong (Litsea firma). Result of the study showed that epiphytic mostly found on the cantilever plant that has thicker bark, groove bark, stringy bark, and a tough bark

Studi Pendahuluan Pengolahan Air Payau Menjadi Air Bersih Dengan Metode Kombinasi Elektrokoagulasi Dan Adsorpsi Menggunakan Karbosil
Get PDFThis study was carried out to investigate treatment of brackish water using a combination of electrocoagulation and adsorption using carbosil prepared from rice husk with pyrolysis method. Electrocoagulation was applied with the aim to remove natural organic matter in the sample, using aluminim as electrodes, with the particular purpose to study the effect of potenstials.For this purpose, electrocoagulation experiments were conducted at potential of 4, 6, and 8 volt at fixed contact time of 60 minutes.The performance of the method was defined in term of absorbance reduction at the wavelengths of 254 and 285 nm, since the absorbance at these two wavelenghts was found to correlate well with the amount of organic matter in the water samples. The treated water was then subjected to adsorption process at different contac times of 5. 10, and 15 minutes, and the performance of the process was evaluated in term of electrical conductivity reduction.The results obtained indicate that for electrocoagulation process, the higest reduction of natural organic matter content was achieved using potential of 8 volt, and adsorption porcess of 15 minutes was found to result in reduction of electrical conductivity from 15.13 mS/cm to 10.10 mS/cm.Characterization of the carbosil using SEM/EDX technique revealed that the carbosil has practically homogeneous surface and able to adsorb salt and several other elements from the brackish water. Key words : adsorption, brackish water, carbosil, electrocoagulatio

Get PDFKadam is one of short rotation plant species because it has a rapid growth. Kadam does not require special treatment to maintenance. General plant maintenance in the early planting was fertilizer. The organic fertilizer such as cow manure compost which added to soil could increase the nutrients substance. The objectives of this research to know the effect of cow manure compost, the best dosage of cow manure compost, and the best altitude for kadam growth. The research was conducted on June—October 2012 at community plantations forest area in West Lampung. The research was arranged in the Block Randomized Design (BRD) with 3 block and 6 treatment. The altitude as block were 124 m, 118 m, and 116 m above sea level. The dosage cow manure compost as treatment were 0 kg/plant, 2 kg/plant, 3 kg/plant, 4 kg/plant, 5 kg/plant, and 6 kg/plant. Bartlett test, analysis of variance, and least significant difference at 5% level were used to analysis of this data. The results of this research showed that dosage of cow manure compost had no significant effect on all variables. Where as the altitude had effect on numbers of leaves only

Get PDFAgroforestry is a land use management system by combining agriculture and forestry and or husbandry to achieved yield optimalization (Indriyanto, 2006). Agroforestry systems with mixed garden pattern consist various types of plants that perform a different composition of plants so there are varied incomes from one place to another. This study aims to: (1) identifying the composition of agroforestry based on INP and its effect on income, (2) analyze the composition of the contribution of agroforestry products to total farm household income. Methods of data collection for species composition using purposive sampling while for the respondent farmers using stratified random sampling. Data analysis using quantitative descriptive analysis method. The results showed that the largest contributes of the composition of plant in three zones, namely the upper, middle, and bottom obtained on the composition of IX which is located in the lower zone of Rp 23,127,404, -/ha/yr with highest INP of cocoa is 94.86%. The magnitude of the average farmer's total income from each source of income from agroforestry to Rp 36.992.171/ha/yr and non-agroforestry amounting to Rp 9.312.500/yr. The magnitude of the contribution of agroforestry systems to farmers' incomes Pesawaran Indah Villages of 91.44%, meaning that agroforestry provides a major contribution to the household income of farmers.

Keberhasilan Hidup Setek Pucuk Jabon (Anthocephalus Cadamba) Dengan Pemberian Beberapa Konsentrasi Rootone-F
Get PDFKadam (Anthocephalus cadamba) is one types of three possible to develop in plantation forest or public forest to suply log necessity in Indonesia. However, the silviculture information on kadam development is still limited especially in providing nurseries. The objective of this research was to find out survival percentage, shooting ability, and rooting ability of kadam shoot cutting with some concentrations of Rootone-F addmited. This research used completely randomized design with four treatments and five replications. Treatments were soaking the bud of kadam shoot cuttings with some of the following Rootone-F concentrations: 0 ppm, 100 ppm, 200 ppm, and 300 ppm. Variables to observe were survival percentages, shoot lengths, shoot diameters, root lengths, and leaf numbers. The results showed that Rootone-F addmited with 200 ppm concentration resulted in the best shoot height, root length, and leaf numbers of kadam shoot cuttings compared with concentrations of 1 ppm, 100 ppm, and 300 ppm. The kadam shoot cutting with 200 ppm Rootone-F concentration had 96% survival, 20.47 cm shoot length, 19.60 root length, and 6.18 leafs. The conclusion was that the concentration of 200 ppm Rootone-F gives the best results
