Abstract
Penelitian ini bertujuan untuk menganalisis perilaku fisik dan mekanik tanah yang distabilisasi dengan penambahan semen PCC dan kapur (CaO) serta penerapan kekangan pasif menggunakan lapisan polimer yang dikuatkan oleh kaca fiber (GFRP). Stabilisasi tanah dilakukan dengan mencampurkan 8% semen dan 4% kapur bedasarkan hasil mix design optimum. Spesimen tanah dipadatkan menggunakan metode pemadatan standar dan diuji pada usia 28 hari. Selanjutnya, benda uji dilapisi dengan 1, 2, dan 3 lapisan GFRP untuk mengkaji pengaruh pasif terhadap kekuatan tekan. Hasil pengujian menunjukkan bahwa penambahan semen PCC dan kapur (CaO) mampu meningkatkan kekuatan tanah secara signifikan. Analisis Mohr-Coulomb menunjukkan nilai kohesi sebesar 0,032 MPa; 0,046 MPa; dan 0,115 MPa, serta sudut geser dalam masing-masing sebesar 45,46°; 45,08°; dan 44,99° untuk setiap jumlah lapisan GFRP. Pengaplikasian GFRP sebagai kekangan pasif juga memberikan peningkatan kekuatan tekan secara bertahap sesuai dengan jumlah lapisan yang digunakan. Penelitian ini membuktikan bahwa kombinasi stabilisasi tanah menggunakan semen PCC, kapur, dan penerapan GFRP secara bertahap efektif dalam meningkatkan sifat fisik dan mekanik tanah, khususnya untuk kebutuhan konstruksi yang memerlukan daya dukung tinggi.

This research aims to analyze the physical and mechanical behavior of soil stabilized with the addition of PCC cement and lime (CaO) as well as the application of passive confinement using a polymer layer reinforced with glass fiber (GFRP). Soil stabilization was carried out by mixing 8% cement and 4% lime based on the optimum mix design results. Soil specimens were compacted using the standard compaction method and tested at 28 days of age. Next, the test specimens were coated with 1, 2, and 3 layers of GFRP to examine the passive effect on compressive strength. The test results show that the addition of PCC cement and lime (CaO) can significantly increase soil strength. Mohr-Coulomb analysis shows cohesion values of 0.032 MPa; 0.046 MPa; and 0.115 MPa, as well as shear angles of 45.46°, 45.08°, and 44.99° for each number of GFRP layers. The application of GFRP as a passive restraint also provides a gradual increase in compressive strength according to the number of layers used. This study proves that the combination of soil stabilization using PCC cement, lime, and the gradual application of GFRP is effective in improving the physical and mechanical properties of the soil, particularly for construction needs that require high load-bearing capacity.
