Abstract

Pertumbuhan jumlah penduduk yang pesat mengakibatkan alih fungsi lahan dari hutan alami gambut menjadi perkebunan kelapa sawit yang mempengaruhi kondisi kimia alami gambut. Gambut yang memiliki keragaman ekosistem yang unik, rentan terhadap kerusakan ekosistem apabila tidak dilakukan pengelolaan yang tepat. Tujuan dari penelitian ini adalah untuk menganalisis sifat kimia tanah gambut di perkebunan kelapa sawit PT Sumbertama Nusapertiwi. Penelitian ini dilaksanakan di Estate Arang-Arang I, PT Sumbertama Nusapertiwi, Kecamatan Kumpeh Ulu, Kabupaten Muaro Jambi. Penelitian ini dilaksanakan selama 5 bulan. Penelitian ini dilakukan menggunakan metode survei, dimana penentuan titik sampel dan pengamatan menggunakan metode purposive sampling (pengambilan sampel didasarkan pada pertimbangan atau kriteria tertentu). Pengambilan sampel tanah gambut berdasarkan peta satuan lahan homogen yang dapat diwakili dengan satu titik pengamatan sampel tanah gambut. Data pengamatan langsung dilapangan terdiri dari ketebalan gambut, tingkat kematangan gambut, dan tinggi muka air. Sampel tanah yang diambil kemudian di analisis untuk memperoleh nilai pH, N-total, P-total, dan K-total dari tanah lokasi penelitian. Hasil penelitian menunjukkan jika pH di angka 3,07 hingga 3,48 (sangat masam), C-Organik di angka 7,33 hingga 57,73% (sangat tinggi) , kadar abu di angka 0,53-87,35, N-Total di angka 0,44 hingga 0,9 (sedang hingga sangat tinggi), P-Total di angka 51,7 hingga 438,9 ppm (sangat rendah hingga tinggi), dan K-Total di angka 10,4 hingga 76,8 ppm (rendah hingga sedang). Rapid population growth has resulted in land conversion from natural peat forests to oil palm plantations, which has affected the natural chemical conditions of Peat, which has a unique ecosystem diversity, is vulnerable to ecosystem damage if not managed properly. The purpose of this study was to analyze the chemical properties of peat soil in the oil palm plantation of PT Sumbertama Nusapertiwi. This research was conducted at Arang-Arang I Estate, PT Sumbertama Nusapertiwi, Kumpeh Ulu District, Muaro Jambi Regency. This research was out for 5 months. This research was conducted using a survey method, where the determination of sample points and observations used a purposive sampling method (sampling is based on certain considerations or criteria). Peat soil sampling was based on a map of homogeneous land units thatcan be represented by one peat soil sample observation point. Direct observationdata in the field consisted of peat thickness, peat maturity level, and water level.The soil samples taken were then analyzed to obtain pH, total N, total P, and total K values from the soil at the study site. The results of the study showed that the pH was at 3.07 to 3.48 (very acidic), C-Organic at 7.33 to 57.73% (very high), ash content at 0.53-87.35, N-Total at 0.44 to 0.9 (moderate to very high), P-Total at 51.7 to 438.9 ppm (very low to high), and K-Total at 10.4 to 76.8 ppm (low to moderate).
