Abstract

Penambangan batubara secara terbuka (open pit mining) merupakan salah satu metode penambangan yang umum dilakukan di Indonesia. Struktur tanah menjadi rusak akibat dari aktivitas penggalian dan penimbunan sehingga menyebabkan kondisi tanah tidak sesuai dengan kondisi awal sebelum penambangan sehingga perlu dilakukan adanya upaya reklamasi lahan pasca tambang. PT Nan Riang merupakan salah satu perusahan pertambangan Batubara yang mengunakan sistem penambangan secara terbuka dan telah melaksanakan upaya reklamasi melalui revegetasi sesuai dengan UU No. 3 tahun 2020. Sengon solomon menjadi tanaman revegetasi yang paling dominan digunakan karena memiliki karakterstik yang adaptif terhadap kondisi tanah yang marginal dan memiliki pertumbuhan yang cepat, sehingga PT. Nanriang setiap tahun rutin melakukan revegetasi dengan tanaman Sengon Solomon. Lahan pasca tambang yang telah direklamasi cenderung memiliki kualitas sifat kimia tanah yang rendah (C-organik, pH dan KTK). Penelitian ini bertujuan untuk mengkaji perubahan beberapa sifat kimia tanah dalam upaya perbaikan kualitas lahan pasca tambang. Penelitian dilakukan dengan metode survei dan pengambilan sampel tanah menggunakan sistem purposive sampling yang didasarkan pada luas areal serta tingkatan umur revegetasi Sengon Solomon. Parameter dalam penelitian adalah sifat kimia tanah (C-organik, pH dan KTK). Tanah yang digunakan dalam analisis adalah sampel tanah komposit sebanyak 28 sampel. Hasil analisis dihubungkan dengan kriteria penilaian sifat kimia tanah (PPT, Bogor 1983) dan akan dibahas secara deskriptif. Hasil penelitian menunjukkan bahwa sifat kimia tanah areal revegetasi Sengon Solomon pada setiap tingkatan umur cenderung tergolong rendah. Nilai pH tanah pada areal revegetasi 1, 2, 3, 4, 5 dan 6 lapisan 0-30 cm dan 30-60 cm tergolong sangat masam-masam (dominan masam) sedangkan pada areal hutan pH tanah pada lapisan 0-30 tergolong sangat masam dan lapisan 30-60 tergolong masam. Kandungan C-organik pada setiap areal revegetasi sangat beragam, C-organik pada seluruh tingkatan umur revegetasi lebih rendah dibandingkan dengan lahan hutan, sedangkan Nilai KTK tanah pada areal tiap umur revegetasi dan areal hutan lapisan 0-30 cm dan 30-60 tergolong rendah. Open-pit mining is one of the most common mining methods in Indonesia. The soil structure becomes damaged as a result of excavation and landfill activities, causing soil conditions that are not in accordance with the initial conditions before mining, so it is necessary to make efforts to reclaim land after mining. PT Nan Riang is one of the coal mining companies that uses an open mining system and has carried out reclamation efforts through revegetation in accordance with Law No. 3 of 2020. Sengon solomon is the most dominant revegetation plant used because it has characteristics that are adaptive to marginal soil conditions and has rapid growth, so PT. Nan Riang routinely revegetates Sengon solomon plants every year. Post-mining land that has been reclaimed tends to have low-quality soil chemical properties (C-organic, pH, and CEC). This study aims to examine changes in several soil chemical properties in an effort to improve the quality of post-mining land. The research was carried out using the survey method and soil sampling using a purposive sampling system based on the area and the age level of Sengon Solomon revegetation. The parameters in the study were the chemical properties of the soil (C-organic, pH, and CEC). The soil used in the analysis was a composite soil sample of 28 samples. The results of the analysis are linked to the criteria for assessing soil chemical properties (PPT, Bogor 1983) and will be discussed descriptively. The results showed that the soil chemistry of the Sengon Solomon revegetation area at each age level tended to be low. The soil pH value in the revegetation area of 1, 2, 3, 4, 5, and 6 layers of 0–30 cm and 30–60 cm is classified as very sour (dominant sour), while in the forest area, the soil pH in layers 0–30 cm is classified as very sour and the layer 30–60 cm is classified as sour. The content of C-organic in each revegetation area is very diverse; C-organic at all levels of revegetation age is lower than that of forest land, while the soil CEC value in each revegetation age area and forest area layer 0–30 cm and 30–60 layers is relatively low.
