Daftar Isi:
- Gunung Palung National Park (TNGP) is a protected forest area that has a very important ecological function. Deforestation activities that occur in the TNGP area have been overcome by implementing reforestation. However, there has not been a scientific study on the impact of reforestation activities on the value of soil fertility. The aim of the research was to compare soil fertility levels based on the physical and chemical properties of soil in open area land, reforestation land, and secondary forests in Gunung Palung National Park, Ketapang Regency. The research method was held by survey, taking soil samples in the land around the Gunung Palung National Park area, i.e., open area land, reforestation land, and secondary forest in Laman Satong village, Matan District, Ketapang Regency. Soil samples were taken by purposive sampling with techniques of sample random sampling (SRS). Soil analysis was carried out in the Laboratory of Chemistry and Soil Fertility, Faculty of Agriculture, Tanjungpura University. The value of soil fertility was held by analyzing the physical and chemical properties. The result of the research showed that secondary forest has a texture of sandy clay, bulk density 0.4 gr/cm3 (SR), pH 3.71 (SM), C-organic 8.17% (ST), N-total 0.86% (ST), CEC 20.27 (S) dan C/N 7.20 (R). Reforestation land has a sandy clay texture, bulk density 1.24gr/cm3 (R), pH 4.39 (SM), C-organic 2.61% (S), N-total 0.,35% (S), CEC 7.87 (R), C/N 7.40 (R). Open area land has a fairly good soil fertility level with a sandy clay texture, bulk density 0,98gr/cm3 (R), pH 4.31 (SM), C-organic 2.26% (S), N-total 0.32% (S), CEC 7.66 (R) dan C/N 8.65 (R). The conclusion of the research showed that the best soil fertility of the land was on the secondary forest, then follow by reforestation land of ASRI and the lowest in open land area.Keywords: Laman Satong Village, Reforestation Area, Soil FertilityAbstrakTaman Nasional Gunung Palung (TNGP) adalah kawasan hutan lindung yang memiliki fungsi ekologi sangat penting. Kegiatan deforestasi yang terjadi di kawasan TNGP telah dilakukan reboisasi, dan belum dilakukan kajian ilmiah dampak dari kegiatan reboisasi terhadap nilai kesuburan tanah. Penelitian ini bertujuan menganalisis tingkat kesuburan tanah berdasarkan sifat fisik dan kimia tanah pada lahan reboisasi yayasan ASRI. Membandingkan tingkat kesuburan tanah pada lahan reboisasi dengan lahan terbuka, dan hutan sekunder di kawasan Taman Nasional Gunung Palung Kabupaten Ketapang. Metode penelitian dilaksanakan dengan metode survei, pengambilan sampel tanah di Desa Laman Satong, Kecamatan Matan, Kabupaten Ketapang. Pengambilan sampel tanah secara sampel random sampling (SRS). Analisis tanah dilakukan di laboratorium kimia dan kesuburan tanah Fakultas Pertanian UNTAN. Nilai kesuburan tanah dilakukan dengan menganalisis sifat fisik dan sifat kimia tanah dengan kriteria kesuburan tanah. Hutan sekunder memiliki tekstur lempung liat berpasir, bulk density 0,4gr/cm3 (SR), pH 3,71 (SM), C-organik 8,17% (ST), N-total 0,86% (ST), KTK 20,27 (S) dan C/N 7,20 (R). Lahan reboisasi memiliki tekstur lempung berpasir, bulk density 1,24gr/cm3 (R), pH 4,39 (SM), C-organik 2,61% (S), N-total 0,35% (S), KTK 7,87 (R), C/N 7,40 (R) . Lahan terbuka memiliki tingkat kesuburan tanah yang tergolong cukup baik dan memiliki tekstur lempung liat berpasir, bulk density 0,98gr/cm3 (R), pH 4,31 (SM), C-organik 2,26% (S), N-total 0,32% (S), KTK 7,66 (R) dan C/N 8,65 (R). Hasil penelitian menunjukkan tingkat kesuburan tanah terbaik pada lahan hutan sekunder kemudian pada lahan reboisasi ASRI dan yang terendah pada areal lahan terbuka.Kata Kunci: Desa Laman Satong, Area Reboisasi, Kesuburan Tanah,
