ABSTRAK
Pesatnya kegiatan pembangunan menyebabkan peningkatan permintaan batuan andesit sehingga membutuhkan eksplorasi lebih dalam untuk mencari jalur batuan andesit di kawasan perusahaan. Penelitian ini dapat mengidentifikasi litologi bawah permukaan di lokasi pengukuran PIT 1 Bagian Selatan PT. Andesit Lumbung Sejahtera. Lokasi titik bor terdekat dengan lokasi penelitian yaitu titik DH_BD014 dan DH_BD08. Pada DH_BD014 didapatkan lapisan bawah permukaan berupa soil di kedalaman 0 – 7 meter, basecourse di kedalaman 7 – 12 meter, dan batu andesit di kedalaman 12 – 60 meter diperkirakan masih menerus sampai bagian yang lebih dalam. Pada DH_BD08 didapatkan lapisan bawah permukaan berupa soil di kedalaman 0 – 7 meter, basecourse di kedalaman 7 – 12 meter, dan batu andesit di kedalaman 15– 50 meter dimungkinkan masih menerus sampai bagian lebih dalam.

ABSTRACT
The rapid development activities have led to an increase in the demand for andesite rocks, thus requiring deeper exploration to find andesite rock paths in the company area. This study can identify subsurface lithology at the measurement location of PIT 1 Southern Part of PT. Andesite Lumbung Prosperous. The locations of the drill points closest to the research location are points DH_BD014 and DH_BD08. In DH_BD014 the subsurface layer in the form of soil at a depth of 0-7 meters, basecourse at a depth of 7-12 meters, and andesite rock at a depth of 12-60 meters is estimated to continue to the deeper parts. In DH_BD08, the subsurface layer was found in the form of soil at a depth of 0-7 meters, basecourse at a depth of 7-12 meters, and andesite rock at a depth of 15-50 meters.Keywords: Andesite, Exploration, Lithology, Drill Point, Soil
