Penelitian ini bertujuan untuk mengembangkan Sistem Informasi Geografis (SIG) yang menyajikan informasi sebaran dan luas rawa gambut di Kabupaten Aceh Barat. Rawa gambut memiliki peran penting dalam ekosistem dan penyerapan karbon, namun informasi terkait sebaran dan pengelolaannya masih terbatas. Dalam penelitian ini, dilakukan pemetaan dan analisis SIG untuk mendapatkan data terbaru tentang sebaran rawa gambut. Hasil penelitian menunjukkan bahwa rawa gambut di Kabupaten Aceh Barat Bagian Barat memiliki luas total 244,15 KM dengan 88 titik rawa gambut. Sebaran rawa gambut meliputi beberapa kecamatan, seperti Samatiga, Arongan Lambalek, Woyla, Woyla Barat, Woyla Timur, dan Sungai Mas. Rawa gambut banyak terdapat di kawasan pesisir, dekat sungai, perkebunan, dan persawahan. Kecamatan Samatiga memiliki jumlah titik rawa gambut terbanyak, sementara Kecamatan Sungai Mas memiliki jumlah yang paling sedikit. Luas rawa gambut terbesar terdapat di Kecamatan Samatiga, mencapai 484,683 m², sementara Kecamatan Woyla Timur memiliki luas rawa gambut terkecil, yaitu 4,617 m². Informasi ini diharapkan dapat membantu semua pihak yang berkepentingan dan menjaga kelestarian rawa gambut di Kabupaten Aceh Barat.

This research aims to develop a Geographic Information System (GIS) that provides information on the distribution and extent of peatlands in West Aceh Regency. Peatlands play a crucial role in the ecosystem and carbon absorption, but information regarding their distribution and management is still limited. In this study, GIS mapping and analysis were conducted to obtain the latest data on the distribution of peatlands. The results showed that peatlands in the western part of West Aceh Regency have a total area of 244.15 KM with 88 peatland points. The distribution of peatlands encompasses several districts, such as Samatiga, Arongan Lambalek, Woyla, Woyla Barat, Woyla Timur, and Sungai Mas. Peatlands are predominantly found in coastal areas, near rivers, plantations, and paddy fields. Johan Pahlawan district has the highest number of peatland points, while Sungai Mas district has the lowest number. The largest extent of peatlands is located in Samatiga district, covering an area of 484,683 m², while Woyla Timur district has the smallest extent of peatlands, which is 4,617 m². This information is expected to assist all stakeholders in preserving the peatlands in West Aceh Regency.
