<![CDATA[In its development, concrete technology has innovated a lot in the use of its materials, such as the utilization of unused material waste. Jejawi is a village area located in OKI Regency and one of the livelihoods of its residents is gardening with the produce of Geda bananas, where after harvesting the banana stems are no longer used and become waste. This study aims to determine the effect of the utilization of Geda banana midrib ash in Jejawi Village as an added material on the quality of concrete. With experimental methods carried out in the laboratory, mixing the concrete material using the SNI quality standard K.225 and then adding variations of Geda Desa Jejawi banana ash which has been burned with an average temperature of 316oC by 2%, 2.5%, and 5%. From the test results, the compressive strength of normal concrete is 225.54 kg/cm2, the compressive strength of the banana ash variation of 2% concrete is 234.76 kg/cm2, the compressive strength of the banana ash variation of 2.5% concrete is 217.19 kg/cm2, and the compressive strength of the 5% banana ash variation of concrete is 203.64 kg/cm2. From the test results, there was an increase in compressive strength in the variation of the addition of 2% banana ash from normal concrete, but it decreased in the 2.5% banana ash variation and decreased again at 5%. So it was concluded that the addition of Geda banana stem ash in Jejawi Village could be used as an additional material for the K 225 concrete mixture at the addition of 2% banana ash]]>

<![CDATA[Research on hollow cross section beams and columns made of laminated bamboo has been carried out. So that the two elements can be assembled into a building structure, it is necessary to do connection. Glued in rod is a new connecting tool whose mechanical properties still need to be studied. For this reasons this research was conducted. To achieve this objective, an experiment was conducted with the independent variables (1) the distance between the two edges, (2) the diameter of the threaded rod, and (3) the embedded length. The results showed that (1) the greater the distance between the two edges, the greater the pull out strength of the glued in rod, (2) the larger the diameter of the threaded rod, the greater the pull out of the glued in rod, (3) the greater the embedded length of the threaded rod, the stronger the pull out of glued in rod, (4) the value of the slip modulus is affected by variations in diameter and embedded length but is not affected by the distance between the two edges. The greatest pull out strength, which is 34.85kN, is achieved at a glued in rod diameter of 12mm with an edge distance of 4.5d and a embedded length of 6d, while the lowest value is 14.38kN lies in steel rods with a diameter of 8mm with a embedded length of 5d and a distance of two edges is 2.5d. The highest slip modulus or the highest stiffness value of 9.75kN/mm is achieved at a diameter of 12 mm with an embedded length of 6d and a distance of two edges of 3.50d. The smallest slip modulus value of 3.75kN/mm was achieved at a diameter variation of 8 mm with an embedded length of 5d and a distance of two edges 2.5d]]>
