Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi SkimCoat dan foam agent 1/60 terhadap pembuatan bata ringan, pada penelitian kali ini dimana semen putih yang di gunakan di ganti dengan Scimcoat. Benda uji berupa kubus dengan ukuran 5 x 5 cm dengan 5 variasi dengan campuran foam agent 1/60 dimana foam agent 0%,25%,50%,75% dan 100% sama dengan jumlah semen, setiap variasi memiliki 18 sampel dengan volume kubus 0,13 cm3 dimana sekali pencampuran menggunakan 5 liter air dengan variasi campuran pasir sungai Mapilli, Menggunakan campuran air tawar dengan FA40 dimana pengganti semen adalah Scimcoat. Selanjutnya melakukan uji tekan umur 7,28,91 hari dengan masing-masing 3 sampel, dan electrical resisticity umur 28 dan 91 hari masing-masing 2 sampel. Hasil pengujian menunjukkan peningkatan nilai uji kuat tekan mencapai nilai optimum 22,21 Mpa dan masuk kategori rendah resiko terpapar korosi.

Abstract

Abstract Soft clay deposits often cause excessive settlement and instability in road embankments. This study investigates ground improvement using prefabricated vertical drains under staged embankment loading through finite element modeling in PLAXIS 2D. The analysis examines consolidation rate, settlement, pore water pressure dissipation, and safety performance for square and triangular drain layouts with spacings of 1.25 m and 1.50 m. Results show that vertical drains accelerate consolidation, reducing the time to reach 90 percent settlement from 8.3 years to less than 3 years, while improving overall embankment stability. The triangular 1.25 m configuration produced the most uniform deformation and fastest consolidation response. The study confirms that optimized drain geometry significantly enhances soft ground performance and provides a practical numerical framework for design applications in tropical regions.
