      Abstract
      Lahan gambut di pulau Kalimantan tersebar dibeberapa provinsi termasuk Provinsi Kalimantan Barat. Kebakaran lahan gambut yang terjadi pada tahun 2018 berlokasi di Kabupaten Kubu Raya tepatnya di sekitar PT. Putra Lirik Domas. Kebakaran tersebut digugat telah menyebabkan berubahnya beberapa sifat tanah yang menuju pada kerusakan gambut. Studi pendahuluan berdasarkan data contoh tanah yang diambil pada saat kebakaran melaporkan bahwa telah terjadi perubahan beberapa sifat kimia tanah yang menuju kepada rusaknya lahan gambut. Penelitian ini bertujuan mengetahui pengaruh kebakaran lahan terhadap perubahan beberapa sifat kimia tanah setelah dua tahun kebakaran. Contoh tanah dari areal lahan tidak terbakar dan terbakar dianalisis beberapa sifat kimia tanahnya. Analisis tanah meliputi pH tanah, C organik, basa-basa seperti Ca, Mg, dan K, serta unsur mikro seperti Cu, Zn, dan Mn. Hasil penelitian menunjukkan pengaruh setelah dua tahun kebakaran lahan gambut tidak memberikan pengaruh yang nyata terhadap perubahan beberapa sifat kimia tanah seperti pH tanah, C organik, Ca, Mg, K, Cu, Zn, dan Mn. Hasil ini menunjukkan bahwa beberapa sifat kimia tanah kembali pada kesetimbangan semula karena tingginya kapasitas menyangga tanah gambut. Kata kunci: contoh tanah, pertumbuhan tanaman, unsur makro, unsur mikro
       
      Peatlands on island of Kalimantan are spread across several provinces including West Kalimantan Province. Peatland fires that occurred in 2018 are located in Kubu Raya Regency precisely around PT Putra Lirik Domas. The fire was claimed to cause the changes leading to peatland damage. The initial study based on samples collected in fire period reported that there were some changes of chemical properties leading to peatland damage. The study aimed to evaluate the effect of land fires on changes in some soil chemical properties after two years of fires. Soil samples of unburned and burned areas subjected to soil analyses. Soil analyses covered soil pH, organic C, basic cations such as Ca, Mg, and K, as well as micronutrient such as Cu, Zn, and Mn. The results showed that after two years peatland fires did not affect the changes of peat soil pH, organic C, Ca, Mg, K, Cu, Zn and Mn. The results suggested some chemical properties return to previous equilibrium due to high buffering capacity of peat soil. Keywords: soil samples, plant growth, macronutrient, micronutrient
