Penambangan batugamping masih<br />membutuhkan data-data eksplorasi dan pengembangan<br />infrastruktur di daerah tersebut. Oleh karena itu data tentang<br />potensi batugamping di Buton Selatan perlu ditingkatkan<br />untuk mendukung kebutuhan pemerintah dan masyarakat.<br />Daerah penelitian berada di Kecamatan Sampolawa,<br />Kabupaten Buton Selatan, Provinsi Sulawesi Selatan.<br />Penelitian ini bertujuan untuk mengetahui karakteristik<br />jenis dan geokimia batugamping formasi Wapulaka sebagai<br />acuan karakteristik batugamping untuk bahan baku industri.<br />Karakteristik jenis batugamping di daerah penelitian terdiri<br />dari jenis wackestone dan jenis packstone. Jenis yang<br />berkembang di daerah penelitian terdiri grain: bioklas, mud:<br />kalsit, pure: vug dan channel. Berdasarkan analisis geokimia<br />batugamping di daerah penelitian memiliki Kandungan<br />CaO hingga 99%, hal ini dipengaruhi oleh adanya cangkang-<br />cangkang atau fosil pada batugamping. Karakteristik fasies<br />dan geokimia menunjukan karakteristik batugamping yang<br />akan digunakan sebagai bahan baku industri seperti: semen,<br />bahan bangunan, industri peleburan dan pemurnian baja.</p> Citra Aulian Chalik Rezki Reyditha Januar Mubdiana Arifin Copyright (c) 2025 Citra Aulian Chalik, Rezki Reyditha Januar, Mubdiana Arifin http://creativecommons.org/licenses/by-nc/4.0 2025-06-23 2025-06-23 26 2 77 85 10.33332/jgsm.geologi.v16i2.857 https://jgsm.geologi.esdm.go.id/index.php/JGSM/article/view/964 <p>Gunung Patuha terletak di Jawa Barat dan<br />memiliki kondisi tektonik yang dipengaruhi oleh aktivitas<br />subduksi di bagian selatan Pulau Jawa. Aktivitas vulkanik<br />yang menghasilkan berbagai jenis batuan, termasuk tuf,<br />lapili, breksi vulkanik, skoria, dan aglomerat. Penelitian<br />ini bertujuan untuk mengidentifikasi karakteristik erupsi<br />Gunung Patuha berdasarkan analisis stratigrafi batuan<br />di Kawah Putih. Metode yang digunakan adalah metode<br />deskriptif kualitatif, dengan data primer diperoleh melalui<br />observasi lapangan dan wawancara, serta data sekunder dari<br />studi literatur. Hasil penelitian menunjukkan bahwa kawasan<br />ini mencerminkan dinamika vulkanisme yang kompleks,<br />dengan berbagai fase erupsi, dari eksplosif hingga efusif.<br />Batuan tuf dan lapili mengindikasikan erupsi eksplosif<br />yang berulang, sementara keberadaan skoria dan aglomerat<br />mencerminkan aktivitas efusif dengan pelepasan gas yang<br />signifikan. Namun, erupsi Gunung Patuha belum mencapai<br />intensitas erupsi Plinian, sebagaimana ditunjukkan oleh<br />tidak adanya deposit pumis yang signifikan dan distribusi<br />material yang cenderung lokal. Penelitian ini diharapkan<br />dapat memberikan pemahaman mendalam tentang proses<br />vulkanisme Gunung Patuha. Temuan ini juga diharapkan<br />dapat berkontribusi pada upaya mitigasi bencana vulkanik<br />di kawasan tersebut.</p> <p><strong>Kata kunci:</strong> Gunung Patuha, stratigrafi, vulkanisme, erupsi.</p> <p> </p> <p><strong><em>Abstract</em></strong></p> <p><em>Mount Patuha is located in West Java and has</em><br /><em>tectonic conditions influenced by subduction activity in the</em><br /><em>southern part of Java Island. Volcanic activity produced a</em><br /><em>variety of rock types, including tuff, lapilli, volcanic breccia,</em><br /><em>scoria, and agglomerate. This research aims to identify the</em><br /><em>eruption characteristics of Mount Patuha based on the</em><br /><em>analysis of rock stratigraphy in Kawah Putih. The method</em><br /><em>used is a descriptive qualitative method, with primary data</em><br /><em>obtained through field observations and interviews, and</em><br /><em>secondary data from literature studies. The results showed</em><br /><em>that the area reflects complex volcanism dynamics, with</em><br /><em>various eruption phases, from explosive to effusive. Tuff and</em><br /><em>lapilli rocks indicate repeated explosive eruptions, while</em><br /><em>the presence of scoria and agglomerate reflects effusive</em><br /><em>activity with significant gas release. However, the eruption</em><br /><em>of Mount Patuha has not reached the intensity of a Plinian</em><br /><em>eruption, as indicated by the absence of significant pumice</em><br /><em>deposits and the localized distribution of materials. This</em><br /><em>research is expected to provide an in-depth understanding</em><br /><em>of the volcanism process of Mount Patuha. The findings are</em><br /><em>also expected to contribute to volcanic disaster mitigation</em><br /><em>efforts in the region.</em></p> <p><em><strong>Keywords:</strong> Mount Patuha, stratigraphy, volcanism,</em><br /><em>eruption.</em></p> Kurnia Maulidi Noviantoro Dwi Novitasari Ayu Firnanda Agung Dwi Firmansyah Ahmad Wildan Nanda Febry Faiza Amalia Fir Atiyatul Mu’awwanah Wahyu Susanti Devia Liza Rahmadani Copyright (c) 2025 Kurnia Maulidi Noviantoro, Dwi Novitasari, Ayu Firnanda, Agung Dwi Firmansyah, Ahmad Wildan Nanda Febry, Faiza Amalia, Fir Atiyatul Mu’awwanah, Wahyu Susanti, Devia Liza Rahmadani http://creativecommons.org/licenses/by-nc/4.0 2025-06-23 2025-06-23 26 2 87 96 10.33332/jgsm.geologi.v26i2.964
