Abstrak

Klasifikasi massa batuan digunakan sebagai parameter penting dalam penentuan reaksi batuan terhadap suatu konstruksi, salah satu metode klasifikasi massa batuan adalah uji beban titik. Uji beban titik lebih disukai karena mudah dalam menentukan kelas massa batuan, baik dari segi biaya maupun waktu. Hingga saat ini banyak ditemukan hasil penelitian yang membahas uji beban titik dengan tujuan untuk mereduksi nilai kesalahan dari hasil pengujian. Dalam penelitian ini dilakukan tinjauan pustaka dari beberapa hasil penelitian untuk mengetahui garis besar hal-hal yang harus diperhatikan dan mengetahui keunggulannya dalam melakukan konversi ke nilai tes yang lain. Hasil penelitian menunjukkan bahwa kemampuan operator, geometri pelat kerucut, perawatan alat secara berkala, panjang lengan pembebanan dan geometri sampel sebagai hal yang perlu diperhatikan dalam uji beban titik dan nilai indeks beban titik dapat diubah menjadi nilai kuat tekan uniaksial, dengan memperhatikan kondisi geologi dan nilai koreksi untuk setiap jenis batuan.
