Abstrak

Uji laboratorium konvensional untuk menentukan Kuat Tekan Uniaksial (UCS) bersifat destruktif, rumit, dan memerlukan biaya tinggi. Schmidt Hammer hadir sebagai alternatif non-destruktif yang cepat dan ekonomis melalui pengukuran Nilai Pantulan. Meskipun korelasi antara kedua parameter ini telah banyak diteliti secara global, penerapannya pada batupasir Formasi Meluhu di Sulawesi Tenggara belum banyak dikaji. Penelitian ini menggunakan pendekatan kuantitatif dengan pengambilan data lapangan menggunakan Schmidt Hammer tipe N di tiga lokasi dan uji UCS laboratorium sesuai standar ISRM. Hasil menunjukkan Nilai Pantulan 14,8-22,4 (kategori "Sangat Lunak" hingga "Sangat-Sangat Lunak") dan UCS 10-111,89 MPa (kategori "Sangat Rendah" hingga "Tinggi"). Analisis regresi eksponensial menghasilkan persamaan y = 0,0639e^0,3305x dengan R² = 0,8906, yang menunjukkan bahwa 89,06% variasi UCS dapat dijelaskan oleh Nilai Pantulan. Temuan ini mengonfirmasi efektivitas Schmidt Hammer sebagai alat estimasi non-destruktif untuk batupasir Formasi Meluhu, meskipun diperlukan kehati-hatian mengingat karakteristik formasi yang heterogen.
