Abstract

This research to investigate the characteristics of wood pellets from wood rubber waste as  alternative renewable energy sources and determine the best treatment. This research was conducted in experiments with completely randomized design (CRD), which consists of three treatments three replications, with the use of wood rubber waste, tapioca flour and water as well as the tools use are peletmill, calory meter combustion bomb, hammermill, oven, container, stirrer, weigher, measure cups, stopwach, wood pellets stove and camera. It can be concluded that the water content wood pellet 15,06% - 17,26%, wood pellet density 0,408 g/cm3 (408 kg/m3) – 0,628 g/cm3 (628 kg/m3), long burn wood pellets 5,42 minutes/200gr – 7,29 minutes/200gr and a calorific value  4029 Kcal/kg - 4106 Kcal/kg. Treatment to three with tapioca powder rubber wood + 30% + 300 ml water have the appropriate or best treatment approach by SNI, where the water content of 15,06%, density of 0,628 g/cm3 (628 kg/m3), long burning 5,42 minutes/200gr and calorific value of 4106 Kcal/kg.

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%.

The purpose of this research is to know the wood type used as the materials of Batak Toba traditional house on Huta Bolon Museum based on public perception. This research used snowball sampling method while the data collectedthrough observation and deep interview towards the informan. The data reduced become a summary which presented on brief description and descriptive qualitative approach for data analysis.
