Abstract

Teak wood (Tectona grandis L.f.) is an important part of building material in Muna, Southeast Sulawesi. This study aims to investigate the characteristics of teakwood Muna namely the degree of crystallinity and the anatomical structure of teakwood after heat treatment for 0.5-12 hours. The results of XRD analysis showed crystallinity diameter without treatment and after treatment of temperature at 90, 120, 150, dan 180 C decreased with increasing temperature namely 5.95; 5.97; 6.02; 6.2; and 7.04 nm. SEM analysis showed teakwood surface profile changes after heat treatment applied.
Candlenut shell as a lignocelullose raw material is a potential by-product for produce activated charcoal. It’s quality are affected by raw material and activated process i.e. temperature, activation time and activating agent.  This paper intends to study the properties of activated charcoal made from candlenut shell. Candlenut shell was carbonization at 500 °Cfor 5 hour. Then activated using phosphoric acid in three different temperatures: 600 °C, 700 °C and 800 °C, in the duration time of 90, Saptadi DARMAWAN; Gustan PARI; Kurnia SOFYAN

Abstract

Candlenut shell as a lignocelullose raw material is a potential by-product for produce activated charcoal. It’s quality are affected by raw material and activated process i.e. temperature, activation time and activating agent.  This paper intends to study the properties of activated charcoal made from candlenut shell. Candlenut shell was carbonization at 500 °Cfor 5 hour. Then activated using phosphoric acid in three different temperatures: 600 °C, 700 °C and 800 °C, in the duration time of 90, 120 and 150 minutes.  The result shows that candlenut shell activated charcoal more influence of temperature than activation time. Overall, the activated charcoal met the Indonesian Standard requirement for commercialised activated charcoal with optimation activation at 800 °C  for 120 minute.   Keywords :    Candlenut shell, activated charcoal, optimation, activation, phosphoric acid
