Abstract

The research aims to isolate and to observe the antagonicity of rhizosphere fungus from onion plant toAlternaria porri. This research has been conducted at Plant Pathology Laboratory and Plant Pest laboratory, Agriculture Faculty, University of Riau from May until July 2017. The research consisted of 6 steps as follow: 1) isolation and purification of the rhizosphere fungus from onion plant used exploration method, 2) antagonicity test of rhizosphere fungus from onion plant againstA. porri used experiment method,3) hyperparasitism test of 5 rhizosphere fungus which have a high antagonicity used observation method. Data collected from step 1 and 3 were descriptively analyzed. Data from step 2 were analyzed by using analysis of variance. The mean of each treatment were compared with Duncan’s New Multiple Range Test(DNMRT) at level 5%. Result of the research showed that there were 16isolates, 5 isolates had a high antagonicity: isolate R6, isolate R11, isolate R10, isolate R4 dan isolate R5. The isolate R6 had the best inhibition growth to A. porri (59,90%), the biggest diameter of the growth (90,00 mm) and the most rapid colony growth (25,00 mm/day). Keyword: Antagonicity,rhizosphere fungus onion

Abstract

Macaca nemestrina is one including appendix II containing list of endangered species. The research aims to understand home range to know daily behavior and mapping range of Macaca nemestrina in the area of Riau University forest and surrounding areas.  This research using a method of direct observation by way of follow, noticed as well as record every activity performed by groups of Macaca nemestrina. The determination of the regional daily range in overlay using software arcgis 10.1. Daily activity were analysed by counting average time daily activity and percentage number of daily activity fauna. Home range Macaca nemestrina were analysed using kernel density estimation (KDE) located on program Geospatial Modelling Environment (GME) and ArcGis 10.1. Home range outermost Macaca nemestrina were analysed by the method of Minimum Convex Polygon (MCP). The result showed that Macaca nemestrina in the area of Riau University forest having broad areas of 176.553 m². Maps of the home range  Macaca nemestrina having range regions core level very high density area of 7.916 m², high area of 11.344 m², mid 41.468 m², low area of 83.28 m² and level of density is very 32.542 m². The activity of Macaca nemestrina is eat, break, migrates, grooming and social interaction. The highest activity is break activity 36,68%, the lowest activity is grooming 4,10%. The percentage of eating 25,33%, social interaction 29,69% and devolve activity 4,20%. To scatter cruiser regions Macaca nemestrina in forest area of Riau University were on the point coordinates 101°22'44,565'BT–101°23'8,918'BT and 0°28'56,122'LU–0°28' 32,798'LU.Keywords: Macaca nemestrina L.,  Forest Areas, Daily Range, Home Range, Core Areas, Coordinate.

Abstract

Edible film is a thin layer of edible material placed on the surface of food products to provide a barrier for moisture, oxygen and solid transfer of the food. The main raw material in making edible film is breadfruit starch, chitosan as stabilizer and sorbitol as plasticizer. Theaimed of this research was to determine the effect sorbitol addition as a plasticizer to the quality of edible film and determine the proper concentration of sorbitol to produce an elastic and not fragile edible film. This research used a completely randomized design (CRD) with five treatments (without sorbitol, 0.4%, 0.8%, 1.2% and 1.6%) and four replications. The result showed that the best sorbitol concentration was S1 (0.4%) with thickness 0.21mm, The rate of water vapor transmission 462.11 g/m2/24 h, tensile strength 10.33 Mpa and elongation 5.29%.Keywords: edible film, sorbitol, plasticizer, breadfruit starch.

Abstract

The purpose of this research was to obtain the right activation time in making coconut shell activated carbon. This research used a Completely Randomized Design with five treatments and four replications which followed by Duncan’s New Multiple Range Test at level 5%. The treatments of this research were KA1 (20 hours activation time), KA2 (22 hours activation time), KA3 (24 hours activation time), KA4 (26 hours activation time) and  KA5 (28 hours activation time). Analysis observed were rendement, water content, ash content, pure carbon and iodine adsorption. Analysis result showed that the variety of activation time did not significantly affected on the yield but significantly affected on the water content, ash content, pure carbon and iodine adsorption. The choosen treatment of activated carbon was 28 hours activation with rendement 95.58%, water content 7.02%, ash content 4.49%, pure carbon 80.79% and iodine absorption 782.62 mg/g.  Keywords: Activated carbon, coconut shell, activation time.
