Kelapa sawit merupakan salah satu komoditi utama hasil perkebunan di Kabupaten Aceh Utara. Berdasarkan Data Dinas Pertanian dan Perkebunan Aceh Utara, diketahui bahwa jumlah produksi buah kelapa sawit mencapai 35.055 ton pada tahun 2021. Keseluruhan produksi tersebut diolah menjadi crued palm oil (CPO) sebagai bahan mentah pembuatan minyak goreng dan mentega. Selain CPO, pengolahan buah kelapa sawit juga menghasilkan produk limbah yang berupa tandan kosong dan cangkang kelapa sawit (Dinas Pertanian dan Perkebunan Aceh Utara, 2021).
Penelitian ini menggunakan metode survai yang didasarkan pada pengamatan langsung di lapangan serta pengamatan di laboratorium. Penelitian ini terdiri dari beberapa tahap yaitu dimulai dari persiapan awal, pengamatan lapangan serta pengambilan sampel tanah, analisis Tekstur,pH,C-organik,N-total,P-total,K-total,KTK dan KB di laboratorium, dan analisis data yang diperoleh. Lalu dilakukan Pengumpulan data iklim meliputi data suhu rerata, curah hujan dan lama bulan kering di Kecamatan Lhoksukon, Kabupaten Aceh Utara yang diperoleh dari Badan Meteorologi, Klimatologi, dan Geofisika Kabupaten Aceh Utara. Selanjutnya pengumpulan data morfologi lahan yaitu lereng, bahaya banjir, kedalaman efektif dan drainase.
Hasil penelitian menunjukan bahwa kesesuaian lahan sawit aktual di Kecamatan Lhoksukon Kabupaten Aceh Utara tergolong pada kelas S3-na,fh atau sesuai marginal dengan faktor pembatas hara tersedia dan bahaya banjir serta kesesuaian lahan sawit potensial di Kecamatan Lhoksukon Kabupaten Aceh Utara tergolong pada kelas S3-fh. Pada Tabel 6 setiap titik sampel diketahui memiliki kelas kesesuaian lahan aktual dan pembatas yang sama yaitu S3-na,fh. Begitu pula pada SPL1 dan SPL2 memiliki kelas kesesuaian aktual dan pembatas yang sama yaitu S3-na,fh. Setiap titik sampel diketahui memiliki kelas kesesuaian lahan potensial dan pembatas yang sama yaitu S3-fh. Begitu pula pada SPL1 dan SPL2 memiliki kelas kesesuaian potensial dan pembatas yang sama yaitu S3-fh. Tingkat kesesuaian lahan aktual perkebunan kelapa sawit di Kecamatan Lhoksukon, Kabupaten Aceh Utara tergolong kelas S3-na,fh. Tingkat kesesuaian lahan potensial perkebunan kelapa sawit di Kecamatan Lhoksukon, Kabupaten Aceh Utara tergolong kelas S3-fh.

Oil palm is one of the main plantation commodities in North Aceh Regency. According to data from the Department of Agriculture and Plantation of North Aceh, it is known that the production of palm fruit reached 35,055 tons in 2021. The entire production is processed into crude palm oil (CPO) as a raw material for cooking oil and butter production. In addition to CPO, processing palm fruit also generates waste products such as empty fruit bunches and palm kernel shells (Department of Agriculture and Plantation of North Aceh, 2021). This research uses a survey method based on direct field observations and laboratory analysis. The research consists of several stages starting from initial preparation, field observations, soil sampling, Texture, pH, Organic C, Total N, Total P, Total K, CEC, and BS analysis in the laboratory, and analysis of the data obtained. Climate data collection includes average temperature, rainfall, and duration of dry months in Lhoksukon District, North Aceh Regency obtained from the Meteorology, Climatology, and Geophysics Agency of North Aceh Regency. Furthermore, land morphology data collection includes slope, flood hazard, effective depth, and drainage. The results of the research indicate that the actual oil palm land suitability in Lhoksukon District, North Aceh Regency is classified as class S3-na,fh, or marginally suitable due to limited nutrient availability and flood hazards. The potential oil palm land suitability in Lhoksukon District, North Aceh Regency is classified as class S3-fh. In Table 6, each sample point is shown to have the same actual land suitability class and limiting factors, namely S3-na,fh. Similarly, SPL1 and SPL2 have the same actual suitability class and limiting factors, S3-na,fh. Each sample point is shown to have the same potential land suitability class and limiting factors, S3-fh. Likewise, SPL1 and SPL2 have the same potential suitability class and limiting factors, S3-fh. The actual land suitability level of oil palm plantations in Lhoksukon District, North Aceh Regency is classified as class S3-na,fh. The potential land suitability level of oil palm plantations in Lhoksukon District, North Aceh Regency is classified as class S3-fh.
