Sifat Fisis Dan Keunggulan Papan Semen Dari Limbah Kulit Batang Sagu

This research aimed to determine the physical properties and advantages of cement boards made from sago stem bark waste based on the test results of several parameters according to JIS A 5908 (2003) standard. The results showed that the physical properties of cement board from sago stem bark waste with the addition of the CaCl2 catalyst were good, with the average value of density ranged from 1.19-1.26 gr/cm³, water content 7,67-8,02%, and water absorption after immersion 2 hours 6,03-7.65% as well as after 24-hour immersion 11,62-12,91%, respectively. The averages swelling value of board thickness was 1.62-12,91% after immersion 2 hours and 1.40-3.41% after immersion 24 hours. Furthermore, what sago bark waste in various positions of the tree trunk (tree base, middle and top) can be utilized to manufacture cement board. The board made from sago stem bark waste at the base position with a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard. Cement board from sago stem bark waste has an excellent waterproof capability and can be used as outdoor materials

Furthermore, sago bark waste in various positions of the tree trunk (tree base, middle, and top) can be utilized to manufacture the cement board. However, the board made from sago stem bark waste at the ground with the addition of a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard.
