Abstract

Agarwood (A. malaccensis Lamk.) is one of the important tropical forest trees, which produces a high economically valuable fragrant resinous wood. The increase of agarwood demand from year to year leads to uncontrolled illegal harvest of this plant from its natural habitat. To encounter this problem, there is an urgent need to develop agarwood plantation. Tissue culture is an alternative method to provide genetically good seedlings for plantation in the future due to its short period and mass quantity of planlet production. In addition, through this method, its might also provide homogenous plant, and free pest and diseases. The objectives of the study were (1) to find out the optimal concentration of BAP or TDZ for inducing shoot multiplication of agarwood in in vitro conditions. MS (Murashige And Skoog, 1962), was used as basal media. The experimental design of the research was completely randomized design (RAL) with treatment of BAP concentration ( control; 0,50 ppm; 0,75 ppm; 1,0 ppm) or TDZ concentration (control; 0,25 ppm; 0,50 ppm; 0,75 ppm), in 3 units, of replicate every units consist of 4 bottles, every bottle containing one explants coming from axillaries and adventitious shoot explants. Results indicated that two types of agarwood explants grown in vitro in MS basal media containing BAP 0,50 ppm or TDZ 0,25 ppm produced the highest number of shoots and leaves of agarwood plantlets, as well as its plantlet shoot length. Keywords: BAP, TDZ, Agarwood, In Vitro.

Abstract

ABSTRACT Tropical rain forest is one type of forest ecosystem that dominated most of Sumatra areal. Arboretum of Faculty of forestry, Lancang Kuning University is the one of tropical rain forest  which the environment becomes a place or habitat for living things. This study aims to describe the various of fungi Basidiomycota. This study was going on May – June 2016. The making technique of data by exkplore an arboretum area to straight saw the fungi. The data collected were characteristic of fungi by morphology and detail pictue to indentification.  The result shows that there are 25 species include in 12 families. Species that is Auricularia auricula, Schyzophylum commune, Ramariopsis kunzei, Agaricus crocopeplus, Lepiota sp, Lycoperdon Pyriforme, Crepidotus sp, Mycena incata, Mycena sp, Marasmieullus candidus, Marasmius andracaceus, Marasmius elegan, Marasmius sp1, Marasmius sp2, Collybia sp, Polyporus sp, Lignosus rhinocerus, Ganoderma aplanatum, Ganoderma sp, Fomitopsis cajanderi, Fomitopsis finicola, Grivola Frondosa, Grivola sp, Coltricia perennis dan Coltricia cinamomea. The number of fungi order were 5 (five)  that could be Auriculateales, Aphylloporales, Agaricales, Polyporales and Hymenochaetales.   Keywords : Basidiomycota, species, the tropical rain forest

Abstract

This study aimed to get a dose of manure and urea appropriate, as well as a good combination on the growth of seedling mahoni (S. macrophylla King). Research conducted an experiment using a completely randomized design (CRD) 2 factors, factors chicken manure (k) consists of four levels i.e. k0 (without manure), k1 (manure, 200 g / seeds), k2 (manure, 400 g / seed) and k3 (manure, 600 g / seed) and factor Urea (n) consists of four levels i.e. n0 (without urea), n1 (Urea 2.5 g / seeds), n2 (Urea 5 g / seed) and n3 (Urea 7.5 g / seeds), each replicated three times. Results of analysis of variance on a test level of 0.05 indicates that Manure significantly affected parameters plant height and number of lateral roots, while the stem diameter, number of leaves and length of main root effect is not real, the best treatment contained in k3 (manure 600 g / seed). Further provision of urea no real effect on all parameters was observed, while the combination of manure and urea real effect only on the parameters of the main root length and number of lateral roots is the best dose at 600 g / plant manure and 7.5 g / seedling urea. In parameter plant height, stem diameter and number of leaves no real effect.

Abstract

ABSTRACT This study aimed to get a dose of right inoculants Fusarium sp. and accelerate the creation of aloes. This research was conducted in test models of agro forestry plots and aloes-owned Balai Penelitian dan Teknologi Serat Tanaman Hutan (BPTSTH) Kuok that located in the village of Kembang Damai Districts of Pagaran Tapah Darussalam Rokan Hulu District. Held for 3 months from July to September 2013. The research method using a randomized block design with 5 treatments, namely in drill without being given inoculant fungi Fusarium sp. (Control), (P1), inoculant 0.5 cc / hole (P2), inoculant 1 cc / hole (P3), inoculant 1.5 cc / hole (P4), inoculant 2 cc / hole (P5). Each treatment was appli.ed in three (3) blocks, the first block to the treatment of Karas trees to plant oil palm on a spacing of 2 meters, block II spacing of 3 meters and a block III at spacing of 4 meters. After 3 months of observation of the extensive infection, discoloration and changes in the level of flavor very significant effect. A symptom of the infection area formed on the aloe tree tends to spread vertically to follow the direction of the vascular tissue of the stem. To aloes ± 6 years old should use a dose of 0.5 cc / borehole inoculant Fusarium sp. Keywords: Agarwood, Inokulsi Fusarium sp., Trees Karas

Abstract

This study aims to determine the use of various fuels and value -added soybean industry users of firewood. Experimental research method is to determine the time and the volume of a variety of fuels . To obtain data on value -added soybean industry firewood users do method survey conducted to tempe entrepreneurs with purposive sampling method.Based on data from the fuel use of the most efficient cooking time to enter into the boiling water experiment is the same volume that is 2 liters of data is obtained using the gas. LPG has a high thermal energy by combustion fuel for 7 minutes with a volume of 0.054 kg of fuel chart . Then followed with the use of kerosene to take 10 minutes and liters of fuel for boiling water 0,01. Fire resulting from green kerosene a little sooty issued. Meanwhile, firewood and wood pellets takes 15 minutes with a volume of 2 kg of fuel.Value of the average profit businesses tempeh is Rp 290,000 per sack (50 kg), which according to tempe entrepreneurs already minimal profit because of the high price of soybeans is currently through the price of Rp 450,000 / sack . With the price of Rp 9.000/kg obtained soybean processing industry added value of Rp 9000/kg soybean tempeh, profit Rp7.500/kg soybean,  margin Rp 11.000/kg soybeans, and other inputs Rp 2000/kg ( 18.18 %) were include wood fuel input of Rp 500/kg soybean or 4.5 %
