“…The materials included medium consistency clay and micro-piles used with apus bamboo Gigantochloa apus from East Java, Indonesia. Apus bamboo was used because it belongs to a strong class II, hence it can be classified as a construction class material (Manik et al, 2017). The bamboo also has the best type of structural gradation due to its maximum compressive load carrying capacity (F c ) which can be precisely and accurately predicted (Bahtiar et al, 2019).…”

The bearing capacity of shallow foundations on soft soils can generally be estimated based on Local Shear Failure (Terzaghi theory). Several researchers previously stated that the installation of micro-piles on the failure area (slide) can increase the shear strength of the soil. This can be followed up by providing micro-pile reinforcement to prevent lateral soil movement. Therefore, this research was conducted to increase the bearing capacity of shallow foundations on medium-consistency soft clay soils that have been reinforced with micro piles. The research was conducted using modeling in the laboratory with a scale of 1:30. The soil sample used was kaolin clay made from slurry made from kaolin powder with a water content (wc = 1.77 LL), liquid limit (LL = 62.35%) and sample diameter (d = 33 cm). The slurry was formed by compacting at a medium consistency level with an undrained cohesion value (cu = 0.397 kg cm-2). The micro-pile material in the form of apus bamboo was installed, varying in diameter (d) 0.2 cm (0.027 B), 0.3 cm (0.04 B), and 0.5 cm (0.07 B); sum (n) 4, 9, 16, and 25; and length (L) 10 cm (1.33B), 13 cm (1.73B), and 16 cm (2.13B) micro-piles. While the foundation model uses a squarefoundation B x B with B = 7.5 cm. The tests were carried out before and after the micro-piles were reinforced with a soil shear failure test. The results showed that a decrease of 0.1B caused an increase in the ultimate bearing capacity of the micro-pile (qult-empirical, 0.1B) from the ultimate bearing capacity before installing the micro-pile. This value is then used to determine the ultimate bearing capacity ratio so that Rq,0.1B = qult-empirical,0.1B/qult-Terzaghi with the optimum bearing capacity ratio occurring at Rq,0.1B with n3 = 16, d2 = 0.04B, L2 = 1.73B.

Kuat tarik lamina bambu sangat bergantung pada orientasi serat bambu, yang dimana serat bambu memiliki sifat tarik yang kuat sepanjang arah serat. Perubahan serat lamina bambu karena proses pengempaan ini perlu untuk diteliti. Adapun tujuan penelitian ini untuk mengetahui pengaruh tahanan lateral balok bambu laminasi terhadap kuat tarik lamina bambu. Tekanan kempa pada balok bambu dengan variasi tanpa dikempa (0 mpa), 1.5 mpa, 2 mpa dan 2.5 mpa. Bahan bakunya adalah bambusa dendrocalamus asper. Pembuatan benda uji pendahuluan untuk pengujian sifat fisika dan mekanika didasarkan pada standar ISO 2004 dan ASTM D143-2008. Setelah dilakukan pengujian, dapat disimpulkan bahwa kuat tarik laminasi bambu petung dengan tekanan lateral 0 MPa dengan rata-rata 330,93 MPa. pada tekanan berikutnya diberikan tekanan sebesar 1,5 MPa mendapatkan hasil rata-rata 343,84. pada tekanan selanjutnya diberikan lagi tekanan sebesar 2 MPa dengan rata-rata 344,75 MPa. setelah penekanan ditambah menjadi 2,5 MPa hasil rata - rata menjadi 328,21 MPa

Bamboo is an extraordinary natural material. Bamboo can grow quickly, is cheap and widely available. The material property is light but harder and stronger than wood or glass fiber composites. The purpose of this study was to determine the effect ofarrangement and size of petung bamboo split fiber to the matrix interface bond of laminated bamboo split fiber. The benefits of this study can contribute knowledge and innovation to the development of science in the field of vessel material technology in education field, especially in the field of shipping. This research was carried out by compressive test, tensile test, and shear test to the matrix interface bond of laminated bamboo and petung bamboosplit fiber with the tangential and radial test directions (x, y, and z axis) using the ASTM D143 standard.After testing, it can be concluded that the tensile strength and compressive strength of the brick arrangement is better, while for the shear strength, it is better in the parallel arrangement, furthermore the thicker the bamboo split size, the greater the stress value. The average results obtained for tensile test is 44 kg/cm2 , the shear test is 38,5 kg/cm2 , and the compressive test is 341,05 kg/cm2 . The average compressive strength of these results can be classified into Strong Class III on BKI (Indonesian Classification Bureau) of Wooden Ships. The direction of the best tensile strength test is on the Y axis, the direction of the best shear strength test is on the Z axis, and the direction of the best compressive strength is on the X axis. The higher the glue Interface value for each cm2 , the greater the interface bond strength due to the need of glue in mm/cm2 is higher, on the contrary the lower the glue Interface value in each cm2 , the lower the interface bond strength due to the need of glue in mm/cm2 is lower.
