The objective of this research was to analyze the physical and mechanical properties of palm oil trunk.  The result showed that in term of the vertical direction the lower part of stem had better physical (density, moisture content and shrinkage) and mechanical (modulus of elasticity, modulus of rupture, hardness, compressive and tensile strength parallel to grain) properties compared with medium and upper end part.  In the horizontal direction the edge part of trunk had better physical and mech Apri Heri ISWANTO; Tito SUCIPTO; Irawati AZHAR; Zahrial COTO; Fauzi FEBRIANTO

Abstract

The objective of this research was to analyze the physical and mechanical properties of palm oil trunk.  The result showed that in term of the vertical direction the lower part of stem had better physical (density, moisture content and shrinkage) and mechanical (modulus of elasticity, modulus of rupture, hardness, compressive and tensile strength parallel to grain) properties compared with medium and upper end part.  In the horizontal direction the edge part of trunk had better physical and mechanical properties than medium and center part.   Keywords :              horizontal direction, palm oil stem, physical pro-perties, mechanical properties, vertical direction
Wood has specific base properties of thermal and combustion. Since being grew normally at marginal soil of mining area, sengon buto, waru and gmelina woods were objectified to investigate thermophisic aspect of their usage as substitution fuel in cement production. Examination based on species, ages and horizontal positions of those woods showed that mean of heating value in oven dry and air dry condition was 4.505 kkal/kg and 4.084 kkal/kg, respectively. Determination of wood substitution to or Tekat DWI CAHYONO; Zahrial COTO; Fauzi FEBRIANTO

Abstract

Wood has specific base properties of thermal and combustion. Since being grew normally at marginal soil of mining area, sengon buto, waru and gmelina woods were objectified to investigate thermophisic aspect of their usage as substitution fuel in cement production. Examination based on species, ages and horizontal positions of those woods showed that mean of heating value in oven dry and air dry condition was 4.505 kkal/kg and 4.084 kkal/kg, respectively. Determination of wood substitution to ordinary fuel was acquired by accumulating heating value with prediction value of plantation biomass potency; and enquiry for 850 ha mining area resulted that waru wood will contribute about 5,14% to coal total requisite per year, gmelina and sengon buto will contribute about 5,03% and 4,49%, respectively.   Keywords:  Wood, heating value, substitution fuel
The acidity of wood and panel product was important factor to impact on metal corrosion and give effect on adhesive curing time.  The objective of this research was  to explore of pH and buffering capacity from nine tropical woods.  Method to determination of pH and buffering capacity  reffers to Johns and Niazi (1980) experiment. The result of this research showed that nine tropical woods which observed had different acidity and buffering capacity. The range of wood acidity had pH 4-7.  The cor Apri Heri ISWANTO; Tito SUCIPTO; Fauzi FEBRIANTO

Abstract

The acidity of wood and panel product was important factor to impact on metal corrosion and give effect on adhesive curing time.  The objective of this research was  to explore of pH and buffering capacity from nine tropical woods.  Method to determination of pH and buffering capacity  reffers to Johns and Niazi (1980) experiment. The result of this research showed that nine tropical woods which observed had different acidity and buffering capacity. The range of wood acidity had pH 4-7.  The correlation value of pH and buffering capacity from this research about 4-5 for base and acid buffering.   Keywords:  acidity of wood, pH, buffering capacity.
