Abstract

Application of Benzyl Amino purine (BAP) to Adenium (Adenium obesum) explants in vitro was conducted at the laboratory of Biotechnology, Faculty Agriculture Islamic University of Riau. This research aims to examine the response of 2 (two) sources of explants material Adenium plant (Adenium obesum). The Completely Randomized Design was used under factorial, consisting two factors: the first factor is the use of explants with two treatment levels, namely: E1 = the use of adenium stem explants and E2 = the use of adenium shoot tip explants. The second factor is the BAP with four treatment levels, namely: B0 = Without BAP (control), B1 = BAP concentrations of 0.1 mg / l, B2 = BAP concentrations of 1.0 mg / l, B3 = BAP concentrations of 10 mg / l. The results show that the treatment had no a significant effect of interaction, but the treatment E2B2 BAP (bud explants with BAP 1 mg /l) showed the highest response to the growth of explants compared to other treatment interactions. The BAP alone on adenium explant response, especially in treatment B2 (BAP 1 mg / l medium). Best explant types obtained were derived from the shoot tip, showing significant effect on the percentage of shoots formation.

Abstract

The arrangement of planting time and corn defoliation is one of the efforts for increasing growth of corn and soybean in intercropping system. The purpose of this research was to study the effect of planting time and corn defoliation and their interaction to growth on corn and soybean and comparise the intercropping and monoculturer system. The experimental design used was factorial with two factors (2 x 3) + 2 monoculture treatments under randomize completed block design with tree replications. The first factor was planting time with two levels i.e. planting corn and soybean in the same time and planting corn 10 days after the soybean. The second was corn defoliation with three levels i.e. no defoliation, defoliation with four leaves left above the cob and defoliation of the adjacent and above corn cob. The results showed that growth of corn and soybean did not affected by planting time but the growth of corn was affected by corn defoliation. Plant height of corn on 6 and 9 weeks after planting was significantly increased when the corn planted 10 days after soybean and corn defoliation with four leaves left above the cob but this treatment was decreased dry weight plant. Intercropping system was not decreased leaf area and dry weight plant of corn and soybean.

Abstract

The population growth is make conversion of green space area to be settlement. This situation supports degradation of environmental quality in urban areas whereas the function of urban forest is affecting the surrounding air directly or indirectly by altering the atmospheric conditions. Conversion of green space area to non-green green space area is a frequently encountered problem lately. Therefore, this research showed that relationship between vegetation index with urban green space. The objectives of this research are: (a) to assess the ability of remote sensing data especially ALOS AVNIR-2 imagery for extraction of vegetation density through vegetation index analysis, (b) to analyze the availability of green space using remote sensing data; and (c) to analyze the density of vegetation on land-use planning based on Urban Land Use Planning (RDTRK) in Ngaglik District.This study was conducted in Ngaglik area using ALOS imagery ANVIR-2 recording in 2009. Distribution of green open space transformation used Normalized Difference Transformation Index (NDVI) and RDTRK documents. The results of this study indicated that urban green space and NDVI can be extracted using ALOS AVNIR-2 imagery. The formula of NDVI was 188.1 x (NDVI)) -0.5617. The vegetation densities can be divided into five classes, non-vegetated area was 13,398,739.48 m² (34.24%), very low vegetation density was 5,381,133.12 m² (13.75%), low vegetation density was 8,143,116.62 m² (20.81%), medium vegetation density was 10,022,040.95 m² (25.61%), high vegetation density was 1,878,236.10 m² (4.80%), and very high vegetation density was 7181.22 m² (0.02%).

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

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%.
