Abstract

Abstract. Durability is defined as a measure of the rock's resistance to weathering and disintegration, when the rock undergoes weathering in a short period of time. This time the slake durability test was carried out with the testing standard of SNI 3406 Year 2011. This test used siltstone in the Balang Island Formation, Samarinda area. The particle size of the silt is midway between that of clay and fine sand. From the results of testing 8 samples of siltstone with 10 cycles that have been carried out, it can be seen that the siltstone in the Balang Island Formation tends to be stronger and the durability index value decreases relatively small from one cycle to the next. The value of Slake durability index (Id2) from each sample sequentially, namely 91.3%, 96.4%, 95.3%, 93.7%, 93.7%, 95.4%. 97.2%, 96.7%. The durability index test obtained an average durability index value (Id2) of 95%, where the value of siltstone at the research site is included in the very high classification. Abstrak. Ketahanan (durability) didefinisikan sebagai ukuran resistensi batuan terhadap pelapukan dan disintegrasi, ketika batuan mengalami proses pelapukan dalam jangka waktu yang singkat. Pengujian slake durability kali ini dilakukan dengan standar pengujian SNI 3406 Tahun 2011. Pengujian ini menggunakan batulanau pada Formasi Pulau Balang daerah Samarinda. Ukuran partikel lanau berada di tengah-tengah antara lempung dan pasir halus. Dari hasil pengujian 8 sampel Batulanau dengan siklus sebanyak 10 kali yang telah dilakukan terlihat bahwa Batulanau pada Formasi Pulau Balang cenderung lebih kuat dan nilai indeks durability mengalami penurunan yang relatif kecil dari siklus satu ke siklus berikutnya. Nilai Slake durability index (Id2) dari masing-masing sampel secara berurutan, yaitu 91.3%, 96.4%, 95.3%, 93.7%, 93.7%, 95.4%. 97.2%, 96.7%. Pengujian durability index tersebut diperoleh rata-rata nilai indeks durability (Id2) sebesar 95% , dimana dengan nilai tersebut batulanau pada lokasi penelitian termasuk dalam klasifikasi sangat tinggi.
