Abstract
Data merupakan komponen paling menadasar dalam kemajuan zaman, permintaan kuantitas dan kualitas data terus meningkat, data dapat digunakan untuk mempelajari fenomena likuifaksi yang dapat menyebabkan kerugian yang tidak sedikit. Likuifaksi terjadi kerena tekanan air pori yang meningkat hingga mengakibatkan tanah kehilangan kekakuan dan kekuatanya, tekanan air pori tanah dapat meningkat dengan signifikan ketika tanah yang perpotensi likuifaksi menerima beban siklik atau pada alam berupa gempa bumi. Penelitian ini dilakukan untuk mengetahui perilaku tekanan air pori tanah pada frekuensi yang berbeda menggunakan shaking table. Penelitian ini meliputi pengumpulan data sekunder sifat fisik tanah dan stratifikasi lapisan penampang tanah, pembuatan alat shaking table, lalu pengujian tekanan air pori tanah menggunakan shaking table yang dilengkapi sensor untuk mengukur tekanan air pori menggunakan percepatan 0.4g dengan frekuensi 1.4 Hz, 1.6 Hz, 1.8 Hz, 2 Hz, dan dengan time history El-Centro N-S yang sudah dirambatkan. Dari hasil pengambilan data sekunder didapat gradasi butir sampel berpotensi likuifaksi dengan kerapatan relatif 40% sehingga perubahan tekanan air pori tanah dapat terlihat jelas ketika dilakukan pengujian, persiapan sampel 20.48 kg tanah dengan tinggi 17 cm dalam kontainer berukuran 18 cm x 15 cm x 25 cm menggunakan metode pluviasi dengan tinggi jatuhan 19 cm. Dari hasil pengujian didapat perilaku tekanan air pori tanah, tekanan air pori tanah meningkat seiring bertambahnya beban siklus pada beban siklik, semakin besar frekuensi yang diberikan semakin besar pula tekanan air pori maksimum dan koefisien regresi kenaikan tekanan air pori terhadap waktu, sedangkan pada pengujian menggunakan beban dinamis perubahan kenaikan tekanan air pori meningkat hanya pada saat beban siklik membesar. Data is the most basic component in the progress of time, the demand for quantity and quality of data continues to increase, data can be used to study the phenomenon of liquefaction which can cause significant losses. Liquefaction occurs because the pore water pressure increases so as to cause the soil to lose its stiffness and strength, the soil pore water pressure can increase significantly when the soil with the potential for liquefaction receives a cyclic load or in a natural form of an earthquake. This research was conducted to determine the behavior of soil pore pressures at different frequencies using a shaking table. This research includes collecting secondary data on soil physical properties and stratification of soil cross-sectional layers, making a shaking table, then testing the pore water pressure using a shaking table equipped with sensors to measure pore water pressure using 0.4g acceleration with a frequency of 1.4 Hz, 1.6 Hz, 1.8 Hz, 2 Hz, and with a propagated El-Centro N-S time history. From the results of secondary data collection, it is obtained that the gradation of the sample grain has the potential for liquefaction with a relative density of 40% so that changes in soil pore pressure can be seen clearly when testing, sample preparation of 20.48 kg of soil with a height of 17 cm in containers measuring 18 cm x 15 cm x 25 cm using the pluviation method with a drop height of 19 cm. From the test results, it is found that the behavior of soil pore water pressure, soil pore water pressure increases with increasing cycle loads at cyclic loads, the greater the frequency given the greater the maximum pore pressure and the regression coefficient of the increase in pore water pressure with time, while the test uses load dynamic changes increase in pore water pressure only when the cyclic load increases. \
