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

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%). The area of green open space was in conformity with the laws in force in the amount of 25.480.722 m² (64.86 %).

Abstract

Test of effect of plant regulator and leaf fertilizer to shallots have conducted in Agriculture and Animal Sciences Faculty, The State Islamic University of Sultan Syarif Kasim Riau. The experimental design used A Completely Randomized Design by one factor, 3 replications, and 7 treatments. The treatments namely were F0 = As controlled, F1= Multi micro fertilizer, F2 = Macro and micro fertilizer, F3 = Macro and micro fertilizer plus vitamins, F4 = Vitamins, minerals and proteins, F5 = Plant regulator with single strength and F6 = Plant regulator with triple strength. Parameters of research were tuber diameter, long of tuber, hight of plant, number of fresh leaf, number of tuber per clump, weight of plant per clump and rates of tuber weight. The results showed that by given minor element (macro-micro), vitamins, protein and Plant Regulator in dosage normal or triple on agriculture system of shallot in optimal condition could not increase the tuber diameter, length of tuber, height of plant, amount of leaf, amount of tuber per clump and weight of plant.

Abstract

Genetic diversity is an important aspect for plant to adapt on environment changes. Information on genetic diversity at individual, species and population levels are required for a basic consideration to formulate strategy conservation and breeding program and utilizing of genetic resources. In the last few decades, the development of DNA based molecular markers techniques has been a significant increase and its are routinely being used in ecological, evolutionary, taxonomical, phylogenetic, population genetic, identification studies of plant sciences. These DNA based markers are distinguished in two types, first non PCR based techniques such as RFLP (Restriction Fragment Length Polymorphism) and second is PCR based techniques such as RAPD (Random Amplified Polymorphic DNA), SSR (Simple Sequence Repeats) and AFLP (Amplified Fragment Length Polymorphism), Cleaved Amplified Polymorphic Sequences (CAPS), Sequence Characterized Amplified Region (SCAR), Single-Strand Conformation Polymorphism (SSCP) and DNA barcoding. These techniques are well established and their advantages as well as limitations have been realized. The review details account of techniques used in identification of markers and their applicability in plant sciences.

Abstract

The natural biocontroller such as bokashi and fermented plant extract (FPE) from some plants are the alternatives to substitute fertilizer and pesticide. This biocontroller is really needed in application of sustainable agricultural system. On the other hand, it can produce nutritious food.This research was done in Bokashi Experimental Garden-EM and Biochemist Laboratory FMIPA UNRI Pekanbaru. The method used in this research was randomized complete design, with 7 treatments of giving bokashi and FPE (bokashi + fermented Annona muricataL. extract, bokashi + fermented Andropogon nardus L. extract, bokashi + fermented Ageratum conyzoidesL. extract, bokashi + fermented Ricinus communis. extract, bokashi + fermented of mixing (Annona muricata., Andropogon nardus., Ageratum conyzoides. and Ricinus communis. extract), bokashi without FPE and without giving bokashi or FPE. Each treatment was replicated for three times and every plot consists of 32 plants. The analysis of data was continued with DNMRT 5 %.The results shows that the giving of bokashi and fermented Annona muricata. extract has better influences compared other treatments. It can improve the height of plant, the leaves content, wet weight of plant and increase the vitamin C content. It is also able to minimize the attacks of the phatogen on Brassica alboglabra’s leaves.

Abstract

The objective of this research is to be able to observe the results of the integration as well as the expression of the desaturase gene in the antisense conformation. The selection of an appropriate tissue culture media is required for a faster growth, development and regeneration of the explant. PCR analysis shows that the putative transgenes were successfully inserted into the target tissue. They were then analysed via gas chromatography to detect its effect on the fatty acid profile. As a result, it was discovered that the three plants contained a higher level of saturated fatty acids (C:12 – C:18), as well as a reduced level of unsaturated fatty acids (C18:1 – C18:3). This probably shows that the stearoyl-ACP desaturase gene might be able to block or reduce the levels of unsaturated fatty acid while increasing the levels of saturated fatty acid. As this are preliminary results further work needs to be carried out to verify this observation.
