Abstract

Oil palm (Elaeis guineensis Jacq.) is a plantation which plays an important role for Indonesia as the leading commodity for export or for the commodity that is expected to increase farmers' income. Of the various factors that cause the production of palm oil decreased by one of them is the problem of drought during the dry season as it is known that palm oil has a shallow root system (root fibers) so that the easy availability of water shortages. This research was carried out experimentally by using Completely Randomized Design (CRD) consisting of 4 (four) treatment with 3 (three) replications, so there are 12 experimental units. Each unit consists of Two plants were taken 1 (one) of plant samples. The tested combined treatment consisting of four levels: A (The Water 2400 ml Marihat D × P), B (Giving Water 2400 Topaz ml D × P), C (Provision of Water 1200 ml Marihat D × P), and D (Provision of Water 1200 ml of D × P Topaz). The parameters observed were plant height increment, number of leaves, corm girth increment, dry weight, seed quality index and proline content. The data obtained were analyzed using ANOVA and followed by further tests DNMRT at level 5%. Results showed that treatment of water supply volume provides significant results on the observation parameters plant height increment, whereas the parameters observed in the number of leaves, corm girth increment, dry weight, and seed quality index showed no significant results after further testing DNMRT at level 5%.

Abstract

This study aims to find out the influences and interactions of cellulolytic microorganisms providing inorganic fertilizer on the growth of palm oil and determine cellulolytic microorganisms dosage and proper inorganic fertilizer on plant oil palm in immature palm plants phase II. Research was done on plantations PT. Tunggal Perkasa Plantation Air Molek District Pasir Penyu, sub-province Indragiri Hulu Riau Province. Research carried out for 4 months starting in October 2012 to the month of January 2013. Randomized Design Block (RDB) factorial with two factors namely cellulolytic microorganisms and inorganic fertilizer with 3 replications used on this research. Data was analyzed using ANOVA and extended with further experiments on standard 5% DNMRT. Parameters of the observation was numbers of total frond, long fronds (cm), number of leaflets (sheets), hump circumference (cm) and plant height (cm). The results showed the granting cellulolytic microorganisms 20 mL / plants and the provision of fertilizer inorganic 1/4 x dose can be suppress the use of fertilizers of inorganic up to 75% on growth oil palm in immature palm plants.

Abstract

This research aimed to determine the effect of the interaction giving cellulolytic microorganisms and inorganic fertilizers or single factor to the growth of immature oil palm plantations. This research has been conducted in land PT.Tunggal Perkasa Plantation Air Molek, District Pasir Penyu,  Indragiri Hulu-Riau. The research was carried out for 4 months, starting from July to October 2012. This study uses a Randomized Block Design factorial with 3 replications, the first factor is the treatment dose selulotik microorganisms composed of 4 levels (0 mL /plant, 10 mL /plant, 20 mL /plant, 30 mL /plant) and the second factor inorganic fertilizer treatment consists of 2 levels (half the recommended dose and 3/4 the recommended dose). The results showed that the interaction of cellulolytic microorganisms and low doses of inorganic fertilizers have  significant effect on the increase in the number of midrib and circumference of stem. Single factor cellulolytic microorganisms giving significant effect on plant height increment, while the single factor inorganic fertilizers giving significant effect on the increase the circumference of stem and number of leaflets.

Abstract

Plants patchouli (Pogostemon cablin Benth.) is one of the essential oil producing plants that are important, foreign exchange accounted for more than 50% of Indonesia's total exports of essential oils. Indonesian patchouli oil is also the largest supplier in the world market with a contribution of 80- 90%. To obtain essential oils that have a yield of patchouli oil and the high alcohol content, it is necessary to consider several factors namely culture technology, climatic factors, especially rainfall, land (topography or shape of the region, elevation) and market opportunities. This research aims to determine the effect of shade and provision of kieserite on crop growth and production of patchouli. The design used in this research is to Plots Separated (Split Plot Design) with the main plot is shaded and the subplot is provision of kieserite. As the main plot of shaded of two levels: N1 = shade with light intensity 50% and N2 = without shade. As a subplot is the awarding of kieserite which consists of three levels P1 = 3,13 g / polybag, P2 = 6,25 g / polybag, P3 = 9,39 g / polybag. The research results obtained are effect of shade and provision of kieserite on crop growth and production of patchouli. Based on the results of the study showed a higher increase of girth increment, the number of secondary branches, number of leaves, canopy dry weight, root dry weight and growth rate relative to the provision of various doses of Kieserite and shade with light intensity 50% and kieserite dose 9,39 g / polybag with no shade showed a higher increase on levels of patchouli essential oils in plants.

Abstract

Giam Siak Kecil Biosphere-Bukit Batu (GSK-BB) is Riau  peatlands area which is largest composed by lowland peat swamp forest ecosystem. Seeing peatland ecosystem getting extreme, there will be small possibility that soil microbes are able to breed optimally, but microbes in tropical land has not been explored. However, the high content of organic matter, allowing soil microbial activity in the organic matter recycle that essential to life such as nitrogen cycle. Non-symbiotic nitrogen fixing bacteria is a free-living bacteria and plays a role in the supply of N in the soil. The results of the isolated and characterization of single bacterial isolates obtained 31 non-symbiotic N fixing of GSK-BB peat Biosphere which allegedly largest to genus Azotobacter, Azospirillium and Clostridium pasteurianum as well as the results of clear zone isolates on the medium modification, from the single isolates contained 14 isolate that potentially in a non-symbiotic N with the largest ratio of clear zone obtained HTA1 10-4 NS-2, HTA1 10-4 NS-1, HTA 4 10-4 NA-1 dan HTA5 10-4 NS-2.
