Abstract

The aim of this research was to determine the influence of ELCPKS and dolomite interaction on oil palm seedling growth and get the best dose for oil palm seedling growth. This research was conducted at the experimental station of Agriculture Faculty, University of Riau on December 2013 until March 2014. This research was arranged on using Completely Randomized Design (CRD) with two factorial: Factor 1 ; dose of ELCPKS, L0 = Without ELCPKS, L1 = 25 g ELCPKS /polybag, L2 = 50 g ELCPKS of  /polybag and L3 = 75 g ELCPKS of /polybag. Factor II ; dolomite D0 = Without dolomite/polybag, D1 = Giving 6 g dolomite /polybag, D2 =12 g dolomite /polybag, D3 = 18 g dolomite /polybag and repeated 3 times, so obtained 48 units experiment. Parameters observed were the increase of plant height, increase of stump diameter, increase of leaves number, root volume, root shoot ratio and dry weight. The result showed that ELCPKS and dolomite interaction affect on; increase of plant height, increase of stump diameter, root crown ratio and plant dry weight, but not significantly on increase of leaves number and root volume. The best results shows on 75 g ELCPKS of /polybag and 18 g dolomite /polybag. ELCPKS treatment on oil palm seedling affect to all parameters, meanwhile the dolomite lime treatment affect to all parameters except on increase of leaves number and root shoot ratio.   Keywords : Oil palm seedling, ELCPKS, dolomite

Agarwood plantis a commodity timber forest products that have high value and become a mainstay Indonesian export products. To support the process of cultivation of agarwood plant isrequired the provision of quality seeds and planting medium is supported by the availability of good and nutrient availability thar enough for the growth of seedlings. The research aim is to know the effect of the interaction of palm oil empty fruit bunch compost and NPK fertilizer and to get the best treatment for the growth of agartwood plant seedling. Theresearch was conducted at the experimental gardenAgricultural Faculty, University of Riau, Pekanbaru from May to September 2014. The research carried out experimentally using a completely randomized design (CRD) factorial consisting of two factors: palm oil empty fruit bunch compost and NPKfertilizer. The first factor is the dose of palm oil empty fruit bunch compost consists of 4 levels, that is: K0 (without palm oil empty fruit bunch compost), K1 (1/3 part of the media), K2 (1/2 part of the media), K3 (2/3 sections of the media). The second factor is the NPK fertilizer application consists of 4 levels: M0 (without NPK fertilizer), M1 (1 g/plant), M2 (2g/plant), M3 (3 g/plant). The results showed that the giving of palm oil empty fruit bunch compost and NPK fertilizer to agarwoor seedling gavethe best effect on fertilizer application of palm oil empty fruit bunch compost2/3 of the media with NPK 2 g/plants against accretion parameters plant height, stem diameter, number of leaves, stems and broad dry weight .   Keyword: Agarwood seedling, palm oil empty fruit bunch compost, NPK fertilizer

Abstract

This researh aimed to determine the effect of water level and organic mulch on physical and chemical properties of peatland in palm oil plantation. Research was conducted for four months which is started on November 2014 to February 2015 at palm oil plantation of ​​PT. Teguh Karsa Wana Lestari (TKWL) in Buantan Besar village, sub district Bungaraya, Siak District. By used 8 years old of palm oil plant. This research used Split Plot Design, consist of 2 factors. The first factor is the water level as main plot, were: the level of 40-50 cm water, 60-70 cm water level and 80-90 cm water level. The second factor is giving organic mulch as sub plot, were: without giving organic mulch, giving palm oil empty fruit bunch (POEFB), palm frond and Mucuna Bracteata. Therefore obtained 12 combinations of treatments and 3 replications, so obtained 36 units experiment. Parameters observed were physical and chemical properties. Data were analyzed by Analysis of Variance (ANOVA) and were further tested by Least Significant Diference (LSD) at5 % level. Based on statistical data obtained non significant effects by water level and organic mulch in physical and chemical properties of peatland. The result of single factor by organic mulch obtained significant effects in physical and chemical properties of peatland. The result of single factor by water level  obtained significant effects in peatland water content parameters.   Keywords : Physical and chemical properties, water level, organic mulch in peatland

Abstract

Agarwood is an aromatic substance formed as brown clumps, blackish brown in the lining of agarwood, divided into 3 classses; agar, kemedangan, ash. Aqualaria malaccencis has been known as an agar producing tree. Naturally, the forming of agar needs teens years. Several method has been known formed agar through wounded to Aquilaria malaccencis, Lamk. The reseach aimed was to test stressing at Aquilaria malaccencis. Lamk in forming agarwood. This research was conducted at Plot Forest Research Institute of Technology Fibers Forest at Ujungbatu, Rokan Hulu, Riau for about 5 months, started from June to October 2011. Aquilaria malaccencis, Lamk, was wound by given fisics stressing consist of without stressing (P0), cordage with 1 ring (P1), cordage with 2 rings (P2), prunning 2/3 part crown (P3), and prunning  1/2 part crown (P4) then combined with biological stressing by inoculation of Fusarium sp. The stressing was designed by randomized block design Duncan’s Multiple Range Test at significant level of 5% was applied to compared physics to agarwood producing. The changed of color and fragrance were analyzed by Non-Parametric Test. Kruskal Wallis at significant level of 5% was applied to evaluate significant treatments. Correlations Test was done between treatment at significant level of 1%. The result showed that Aquilaria malaccencis, Lamk, with fisics tressing (P1, P2, P3, dan P4) showed wood colour changed after 1 month inoculation of Fusarium sp. Stressing cordage with 2 rings (P2) which followed by inoculation of Fusarium sp at Aquilaria malaccencis, Lamk, resulted 26,76 g  dryweight of brown agar with best fragrance at level 2 after 5 months stressing. Based on statistical analysis, there were significant between stressing and agar formed. The best stressing at Aquilaria malaccencis, Lamk, was cordage with 2 rings. The result of correlations test showed strong to very strong of infection area, color changing, fragrans and dryweight of agarwood   Key words: Aquilaria malaccencis, Lamk., agarwood, stressing
