Abstract
Chicken claw foundations have proven to be an effective solution in increasing the stability of building structures, especially in areas with soft soil conditions and a high risk of earthquakes. Hardiyatmo's research (2015) shows that this system is able to increase the bearing capacity of the soil by up to 35% through optimizing the stiffness of the foundation plate so that it is suitable for application in infrastructure projects on problematic soil. Meanwhile, Prakoso and Kumara (2018) revealed that the chicken claw foundation design can reduce the earthquake response of multi-storey buildings by up to 20% and increase construction cost efficiency by 15% compared to conventional methods. Material innovation is also an important factor, as found by Kusuma and Hidayat (2020) who show that the use of high quality concrete and geotextiles is able to optimize bearing capacity and withstand deformation due to earthquakes up to 25% better than standard materials. These studies confirm that chicken claw foundations are an adaptive and economical alternative for earthquake-prone areas with challenging soil conditions

Abstrak
Pondasi cakar ayam terbukti menjadi solusi efektif dalam meningkatkan stabilitas struktur bangunan, terutama pada daerah dengan kondisi tanah lunak dan resiko gempa tinggi. Penelitian Hardiyatmo (2015) menunjukkan bahwa sistem ini mampu meningkatkan daya dukung tanah hingga 35% melalui optimalisasi kekakuan pelat pondasi sehingga cocok diterapkan pada proyek infrastruktur pada tanah bermasalah. Sedangkan Prakoso dan Kumara (2018) mengungkapkan bahwa desain pondasi cakar ayam dapat menurunkan respon gempa gedung bertingkat hingga 20% dan meningkatkan efisiensi biaya konstruksi sebesar 15% dibandingkan dengan metode konvensional. Inovasi material juga menjadi faktor penting, seperti yang ditemukan oleh Kusuma dan Hidayat (2020) yang menunjukkan bahwa penggunaan beton dan geotekstil berkualitas tinggi mampu mengoptimalkan daya dukung dan menahan deformasi akibat gempa hingga 25% lebih baik dibandingkan material standar. Studi-studi ini menegaskan bahwa pondasi cakar ayam merupakan alternatif yang adaptif dan ekonomis untuk daerah rawan gempa dengan kondisi tanah yang menantang.
