Abstract

This study aims to determine the influence and dosage of compost fertilizer (Greenbotane) which produces the best growth of palm seedlings.Penelitian conducted in Experimental Garden Faculty of Agriculture University of Riau. Type of land used is Mineral Acid. The research was conducted for four months starting from August to December 2016. The research was conducted experimentally using Randomized Complete Random Design (RAL), which consisted of 5 treatments with 4 replicates. The total experimental unit amounted to 20 plots, in which each plot contained 2 plants . The observed data were analyzed statistically by using Analysis of Varian (ANOVA), then continued by the Multiple Range Test of Duncan at 5% level. The observed parameters consist of plant height, number of leaves, diameter of stump, wet weight of plant, dry weight and root canopy ratio. The results show that compost fertilizer (Greenbotane) treatment can increase plant height, cobweb diameter, wet weight and dry weight of plant. The best treatment for oil palm crop is fertilizer application (Greenbotane) with dose 200g / polybag.Keywords: Greenbotane compost, palm oil

Abstract

The aimresearchof determine the influence of M. bracteata and the slope of land to the diversity of soil macrofauna and root growth of oil palmsimmature. This research was conducted in PTPN V Unit LubukDalam, Siak and analysis of soil macrofauna in the Soil Laboratory Faculty of Agriculture, University of Riau. This research has been carried out from January to April 2016. The study was conducted using Split Plot Design. The level of the slope (K) as the main plot consists of: K0 = 0-3%,K1 =>3-8%, K2 = >8-15%. Employing Mucunabracteata (M) as the subplot consisting of: M0 = land clearning, M1 = land that is overgrown. The parameters measured were the number of population density, relative density, diversity index (H’) soil macrofauna, root dry weight, root volume and root occupy. The research showed: (1) land overgrown palm M. bracteata has a population density number, relative density and the diversity of the soil macrofauna higher and better root growth compared with that land clearning; and (2) The higher the slope (%) resulting in a population density, relative density and the diversity of soil macrofauna are getting lower and root growth decreases. Keywords: Mucuna bracteata, land slope and macrofauna

Abstract

The study was aimed to get the best treatment ratio of utilization water hyacinth cellulose as a base material in the manufacture of edible film with the addition of glycerol and carrageenan. The study was conducted using Completely Randomized Design (RAL) consisting of six treatments with each treatment repeated three times. The treatments in this study were E0 (without addition of water hyacinth cellulose), E1 (percentage of 1% water hyacinth cellulose), E2 (percentage of water hyacinth cellulose 2%), E3 (percentage of water hyacinth cellulose 3%), E4 (percentage of water hyacinth cellulose 4%) and E5 (percentage of 5% water hyacinth cellulose). The observed parameters were thickness (mm), transparency, water vapor transmission rate (g/hour.m2), water resistance (%), tensile strength (MPa) and percent elongation (%). The data obtained were tested statistically using ANOVA. If F arithmetic was greater than F table then analysis will be continued with DNMRT test at 5% level. The result showed that the percentage of addition of water hyacinth cellulose powder had significant effect on thickness, transparency, vapor transmission rate, water resistance, tensile strength and percent elongation. The best treatment is treatment with percentage of 1% cellulose powder added with thickness value     0,139 mm, transparency 1,029, vapor transmission 1,323 g / hour.m2, water resistance 5,829%, tensile strength 6,104 MPa and percent elongation 23,885%. Keywords: Cellulose, water hyacinth, glycerol, carrageenan.

Abstract

White root fungus (Rigidoporus microporus) is a major pathogen in the rubber plant that is difficult to control because it has a structure that survives in plant tissue.  Biological control of endophytic fungi is very potential to control  Mushrooms JAP.  This research was conducted at Plant Disease Laboratory of Agriculture Faculty of Riau University and Photomikografi Laboratory, FMIPA Organic Chemistry Laboratory Department of Biology, University of Riau, Simpang Baru Campus Tampan District, Pekanbaru.  Starting from March to June 2017 with the aim of Identification of morphological cultivation of endophytic fungi and In-Vitro microbial test on Rigidoporus microporus in rubber plant.  The study consisted of site survey, sampling, tool sterilization, PDA & PDB media manufacture, fungi isolation, rubber plant tissue incubation, purification and observation. Based on the results of isolation and identification of endophytic fungi from plant tissue obtained 3 isolates where there are 2 types of Aspergilus SP fungus and 1 type of Trichoderma sp.  All three isolates are potential endophytic fungi to control JAP disease in rubber. Hypovirulensi test results did not produce symptoms of chlorosis or necrosis after inoculated Trichoderma 48 hours after incubation. Observation of secondary metabolite Trichoderma sp endophytes after 14 days incubated in a petridish showed metabolite results with a mean of 0.75 cm clear zone. Keywords: Rigidoporus microporus, Identification, Endophytic Fungi

The purpose of this research was to obtain the ratio of chayote extracts and lime extractsin the manufactured of syrup. This research used Complete Randomized Design (CRD) with four treatments and four replication which followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatments in this research included LS0(ratio of chayote extracts and lime extracts 100 : 0), LS1 (ratio chayote extracts and lime extracts 95 : 05), LS2 (ratio chayote extracts and lime extracts 90 : 10), LS3 (chayote extracts and lime extracts 85 : 15). The results of analysis showed that the ratio of chayote extracts and lime extracts significantly effect on acidity (pH), viscosity, total dissolve, sucrose content and organoleptic value (colour, flavour, taste, consistency and overall acceptability). The bestsyrup was LS3 with acidity (pH) 4,45, viscosity 528,33cP, total dissolved 71,03 brix, sucrose content 65,44%. Overall preferred by the panelists with description the colour of rather murky, not falvorful chayote and falvorful lime, sweet taste little  acidic and condensed.   Keywords: Syrup, chayote, lime.

Abstract

Paraserianthes falcataria (L.) Nielsen is a fast-growing plant species that has been widely recognized by society in the development of forest plantations. Paraserianthes falcataria (L.) Nielsen has many uses ranging from leaves, stems to the roots. People generally just let the Paraserianthes falcataria (L.) Nielsen seeds grow naturally without making the treatment of the seeds. Seed treatment is by using plants that contain a disinfectant or antiseptic, and easily found around the neighborhood, including the Piper betle Linn. plant. This research aimed to determine the effect of soaking Piper betle Linn. leaves on the quality of the seed and determine the length of immersion Piper betle Linn. leaf which is optimal to protect seed quality. The research was compiled in a completely randomized design (CRD) with 5 treatments and 4 replications. The treatment consisted of soaking Paraserianthes falcataria (L.) Nielsen seeds with water immersion of Piper betle Linn. leaves for 10 minutes, 20 minutes, 30 minutes, 40 minutes and 50 minutes. Data were analyzed by analysis of variance using SAS 9.1.3 Portable. And than, continued with DNMRT double distance test at 5% level. The research results showed that the duration of Piper betle Linn. leaf soaking has an effect on seed germination and improve the quality of seeds during storage. The optimal time for Piper betle Linn. leaf soaking is 30 minutes with germination percentage of 86.00%, germination speed of 2.73 days and seed germination time of 8 days. Keywords: Paraserianthes falcataria (L.)
