Penelitian ini dilakukan di kawasan wisata alam bukit lawang, kecamatan bohorok, kabupaten langkat, sumatra utara, dengan tujuan memetakan kondisi geologi permukaan meliputi litologi, struktur geologi, dan geomorfologi, serta menginventarisasi potensi geowisata berdasarkan aspek geodiversity. metode penelitian menggunakan pemetaan geologi yang mencakup analisis litologi, struktur, dan geomorfologi, serta analisis petrografi sebagai data pendukung. hasil penelitian menunjukkan bahwa daerah penelitian tersusun atas batulanau malihan dari formasi bahorok, batupasir karbonatan dan batugamping terumbu dari formasi belumai, serta batuserpih karbonatan dari formasi baong. struktur geologi yang teridentifikasi meliputi kekar pada batulanau malihan, struktur berongga pada batugamping terumbu, serta struktur berlapis pada batuserpih karbonatan. bentuklahan yang berkembang terdiri atas geomorfologi struktural, denudasional, dan karst. potensi geowisata yang teridentifikasi di daerah penelitian terdiri atas enam objek, yaitu satu air terjun, dua gua (cave rock cafe dan bat cave), dua sungai (sungai bahorok dan sungai landak), serta rock island yang berupa kumpulan batugamping terumbu. kesimpulan penelitian menunjukkan bahwa kawasan penelitian memiliki keragaman geologi yang signifikan sehingga layak dikembangkan sebagai destinasi geowisata berkelanjutan. penelitian ini bermanfaat sebagai sumber informasi geologi terkini dan dasar penyusunan strategi pengembangan pariwisata. kata kunci : geowisata, geodiversity, bukit lawang, formasi bahorok, karst

This research was conducted in the Bukit Lawang Nature Tourism Area, Bahorok District, Langkat Regency, North Sumatra. The objective of this study is to map the surface geological conditions, including lithology, geological structures, and geomorphology, as well as to inventory the geotourism potential based on geodiversity aspects. The research method employed geological mapping, which encompasses lithological, structural, and geomorphological analyses, supported by petrographic analysis. The results indicate that the study area is composed of metamudstone from the Bahorok Formation, carbonate sandstone and reef limestone from the Belumai Formation, and carbonaceous shale from the Baong Formation. Identified geological structures include joints in the metamudstone, vuggy structures in the reef limestone, and bedded structures in the carbonaceous shale. The landforms developed in the area consist of structural, denudational, and karst geomorphologies. The identified geotourism potentials within the study area include six sites: one waterfall, two caves (Cave Rock Cafe and Bat Cave), two rivers (Bahorok River and Landak River), and the Rock Island, which is a cluster of reef limestones. The study concludes that the research area possesses significant geological diversity, making it suitable for development as a sustainable geotourism destination. This research serves as an up-to-date geological information source and a basis for formulating tourism development strategies.
