Daftar Isi:
- Tailing emas merupakan limbah pemurnian emas yang telah diambil mineralnya. Pemurnian emas oleh masyarakat secara tradisional sebagian besar masih menggunakan bahan beracun berbahaya yang mencemari tanah, sungai maupun danau sehingga dapat mencemari lingkungan dan berbahaya bagi makhluk hidup. Fitoremediasi merupakan salah satu cara reklamasi dalam mengurangi cemaran limbah tersebut menggunakan tanaman. Mangium (Acacia mangium) merupakan salah satu tanaman yang sering digunakan untuk reklamasi lahan tambang. Namun, kondisi tailing tersebut membuat mangium sulit untuk dapat bertahan maupun tumbuh dan berkembang sehingga dibutuhkan input tambahan berupa fungi ektomikoriza jenis Scleroderma sp. Penelitian ini bertujuan menguji kemampuan hidup mangium dan menganalisis peran mikoriza dalam pertumbuhan mangium pada media tailing emas. Metode yang digunakan yaitu metode eksperimental Ulfa Luthfiana menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan masingmasing 5 ulangan. Perlakuan yang diberikan yaitu campuran topsoil dan arang sekam (1:1) bermikoriza, campuran top soil dan arang sekam (1:1) tanpa mikoriza, campuran top soil, tailing dan arang sekam (1:1:1) bermikoriza, campuran top soil, tailing dan arang sekam (1:1:1) tanpa mikoriza, campuran tailing dan arang sekam (1:1) bermikoriza, dan campuran tailing dan arang sekam (1:1) tanpa mikoriza. Total keseluruhan percobaan yang dilakukan adalah 90 satuan percobaan. Data diolah menggunakan analisis ragam (Anara) dan diuji lanjut menggunakan uji Beda Nyata Terkecil (BNT). Hasil penelitian ini adalah bahwa mangium memiliki kemampuan hidup yang cukup tinggi pada media tailing meskipun memiliki pertumbuhan yang kurang baik. Pertumbuhan terbaik yaitu pada perlakuan media tanah tanpa mikoriza. Kolonisasi ektomikoriza pada akar mangium belum berperan dalam membantu pertumbuhan mangium dan kolonisasi terbesar ada pada media tailing. Kata Kunci: Acacia mangium, ektomikoriza, fitoremediasi, Scleroderma sp., tailing emas. Ulfa Luthfiana ABSTRACT Gold tailings was the waste of the gold mining processing that the mineral has been taken. The processing of gold mining carried out by the community mostly used hazardous toxic materials which polluted the soil, rivers and lakes. It polluted the environment and harmful to living things. Phytoremediation is one way of reclamation in reduced contamination of hazardous waste using plants. Mangium (Acacia mangium) is one of the plants that is often used for mining land reclamation. However, the land conditions such as tailings make it difficult for mangium to survive and grow and develop so that additional input is needed in the form of ectomycorrhiza fungi (Scleroderma sp.). This study aimed to examine the ability of life of mangium in gold tailings media and analyze the role of mycorrhiza in the growth of mangium in gold tailings media. The method used the experimental method using a Completely Randomized Design (CRD) with 6 treatments and each of Ulfa Luthfiana 5 replications. The treatments given were a mixture of topsoil and husk charcoal (1: 1) with mycorrhiza, a mixture of top soil and husk charcoal (1: 1) without mycorrhizae, top soil mixtures, tailings and husk charcoal (1: 1: 1) with mycorrhiza, mixtures top soil, tailings and husk charcoal (1: 1: 1) without mycorrhiza, mixtures of tailings and husk charcoal (1: 1) with mycorrhiza, and mixtures of tailings and husk charcoal (1: 1) without mycorrhiza. The total number of trials conducted was 90 experimental units. Data was processed using variance analysis and tested further using the Least Significant Difference (LSD) test. The results obtained in this study were mangium had a fairly high life ability in tailings media even though it has poor growth. The best growth is owned by the treatment of soil media without mycorrhiza. Colonization of ectomycoriza in mangium root has not yet played a role in helping the growth of mangium and the largest colonization in the tailings medium.
