Publisher : Universitas Bengkulu

The Compressed bar at the frame, columns, and other structures is always probably happened buckling. The experiment is conducted to investigate the behavior of buckling at the bar of lath shaped bamboo petung and the buckling strength of the experiment result with the theory result (the equation of tetmayer and euler, proposal of morisco, and atrops (D/T=0)). In the research, it is conducted testing of the mechanic character of bamboo and wood specimens, testing of resin, and buckling testing with the compressed testing principle. The testing result showed that buckling happened at the lath shaped bamboo petung is influenced by the length of bar, the resin strength, and the quality of work. The buckling stress of the experiment result was higher than the result of morisco proposal, but it’s less than the result of tetmayer and atrops (D/T=0), so that the equation of morisco proposal is safe to used at the compressed bar design.

This study was aimed to determine the effect of adding palm shell ash to the red brick compressive strength. Palm shell ash is pozzolanic and contains about 60% silica and when it is mixed with clay bricks, the strength become stronger. This study used two methods of treatment of the palm shell ash, oven and unoven. Bricks was made in this study using SII-0021-1978, while the red brick compressive strength was tested in this study using SNI 03-4164-1996. TheSpecimens were 146 cubes with a size of 5 cm on each side. The Variations in ash were used as an added ingredient of red brick at 0%, 4,3%, 8,6%, 12,9%, 17,2% and 21,5%. Specimens molded and dried for about 1 week and then burned in a red brick factory. The test results showed the addition of oven and unoven palm shell ash was increased the compressive strength of red brick. The addition of unoven palm shell ash was decreased the water absorption of the red brick and made the red brick lighter. The Lightest weight of the brick occurred in 8,6% of unoven palm shell ash was 12.96% of the normal one. The bigest compressive strength occured in 4,3% oven palm shell ash that was 112.82% of the normal red bricks. The smallest water absorption occurs in 8,6% of unoven palm shell ash was 18.07% of the normal red bricks.
