Abstract. Sand mining plays an important role in meeting the demand for construction materials and infrastructure development. Increased construction activity has led to a continuous rise in demand for sand, requiring mining companies to achieve their production targets on a sustainable basis. To meet these targets, well-structured mining planning is required to ensure that mining activities run according to plan. Open pit mining planning includes determining the stages of mining, planning mine progress, and controlling production. CV Bumi Pasir Makmur is one of the sandstone mining companies operating in West Java Province. Based on the mining business license, CV Bumi Pasir Makmur has an IUP area of 16.2 Ha located in Margaluyu Village, Leles District, Garut Regency, West Java Province. The study involved a detailed analysis of the geological model and resource estimation through geophysical methods i.e. geoelectricity, as well as the geotechnical aspects required for a stable slope. The design emphasized the creation of an effective sequence phase that would simplify operations and improve safety during mining activities. Close monitoring of production plans against actual performance is recommended to ensure continued alignment with established objectives. Based on the results of data analysis, sandstone mining activities on a 16.2 hectare area at CV Bumi Pasir Makmur identified proven reserves of 1,979,875.00 BCM of sandstone. The study targets an annual production rate of 395,975.00 BCM, projecting a total operational life of 5 years for the mining site.

Abstrak. Kegiatan penambangan batupasir memiliki peranan penting dalam memenuhi kebutuhan material konstruksi dan pembangunan infrastruktur. Peningkatan aktivitas pembangunan menyebabkan permintaan batupasir terus meningkat sehingga perusahaan tambang dituntut untuk mencapai target produksi secara berkelanjutan. Untuk memenuhi target tersebut, diperlukan perencanaan tambang yang tersusun dengan baik agar kegiatan penambangan berjalan sesuai rencana. Perencanaan tambang terbuka meliputi penentuan tahapan penambangan, perencanaan kemajuan tambang, dan pengendalian produksi. CV Bumi Pasir Makmur merupakan salah satu perusahaan tambang batupasir yang beroperasi di Provinsi Jawa Barat. Berdasarkan izin usaha pertambangan CV Bumi Pasir Makmur memiliki luas IUP 16,2 Ha yang berada di Desa Margaluyu, Kecamatan Leles, Kabupaten Garut, Provinsi Jawa Barat. Penelitian ini melibatkan analisis rinci model geologi dan estimasi sumber daya melalui metode geofisika yaitu geolistrik, serta aspek geoteknik yang diperlukan untuk lereng yang stabil. Rancangan tersebut menekankan pada perancangan mine sequence yang efektif yang akan menyederhanakan operasi dan meningkatkan keselamatan selama kegiatan penambangan. Pemantauan yang ketat terhadap rencana produksi terhadap kinerja aktual direkomendasikan untuk memastikan keselarasan yang berkelanjutan dengan tujuan yang telah ditetapkan. Berdasarkan hasil analisis data, kegiatan penambangan batupasir pada area seluas 16,2 hektar di CV Bumi Pasir Makmur mengidentifikasi adanya cadangan sebesar 1.979.875,00 BCM batupasir. Penelitian ini menargetkan tingkat produksi tahunan sebesar 395.975,00 BCM, memproyeksikan total umur operasional selama 5 tahun untuk lokasi penambangan.
Kata Kunci: Optimasi, Batupasir, Sequence, Cadangan.
