Pengaruh Pola Susunan Laminasi Balok Bambu Tali (Gigantochloa apus Kurz) Terhadap Kerapatan, Delaminasi dan Keteguhan Patah
Abstract: Bamboo is a
potential species as its price is relatively less expensive than wood logs
while it also represents a fast growing plant and is easy to plant. In general
bamboos in South Kalimantan have not been exploited optimally. Its utilization
for construction purposes is very limited. This study aims to identify the
effects of lamination pattern on the density, delamination and rupture
impregnability (Modulus of Rupture, MoR) of laminated bamboo blocks, with the
combinations of a (reed wall- reed wall), b (reed wall-husk), and c (husk- husk
and reed wall-reed wall). The results showed that lamination patterns affected
the density, delamination and rupture impregnability of the laminae produced.
The average density (kg/cm3) is 0.5321, 0.6923, and 0.6746 for treatments a, b,
and c respectively. Delamination percentage (%) is 6.55, 16.65, and 21.1, while
the rupture impregnability level (kg/cm2) is 228.99, 152.09,and 171.97 for
treatments a, b, and c respectively. Delamination percentage of less than
10% suggets that the laminae produced
can be used for building construction. that It is concluded that lamination
pattern of reed wall-reed wall gave the best performance of bamboo lamina with
the average density of 0.5321 kg/cm3, the delamination percentage of 6.55% ,
and the rupture impregnability level of 228.99 kg/cm2.
