Abstract

Tailing was residue of gold mining process which lead to some environment problem. Beside containing heavy metal, tailing have lower soil fertility, physical, chemical and biological characteristics. To overcome this problem, revegetation activities was needed. The succesfulness of revegetation activities determined by adaptive trees selection. Local species was recommended because suitable to local climate and soil conditions, in this study we choosed toba benzoin (Styrax sumatrana) and suren (Toona sureni). The objective of this research was to get information about adaptability of toba benzoin and suren on growth media containing tailings. Research was conducted in green hause Faculty of Agriculture, University of Sumatera Utara. Factorial Randomized Completely Design with two factor were used in this research. The first factor was growing media (Factor A) and the second factor was seedling species (Factor B). The observed parameter were seedling height, seedling diameter, seedling dry weight, primary root lenght, shoot-root ratio and chemical properties of media. The results showed that the species and growing medium significantly affected the height growth of seedlings, seedling diameter, seedling dry weight and length of the primary root. The addition of topsoil and compost able to improve the chemical properties of the tailings are used. Tailings media and compost with composition ratio of 1:1 is recommended for Toba benzoin and Suren. That media provide the most optimal results of Toba benzoin and suren growth.

Abstract

Timbang Lawan merupakan salah satu desa di Kecamatan Bohorok, Kabupaten Langkat dan menjadi zona penyangga (buffer zone) Taman Nasional Gunung Leuser. Salah satu masalah desa adalah kemunculan harimau sumatera (Panthera tigris sumatrae) yang menyerang ternak warga di pinggiran hutan. Selain mengakibatkan kerugian materi, serangan harimau sumatera berpotensi menimbulkan persepsi negative terhadap satwaliar tersebut. Oleh karena itu kegiatan pengabdian USU ini dilakukan dengan tujuan untuk membangun harmoni antara penghidupan masyarakat dengan konservasi harimau. Kegiatan terdiri dari lima bagian, yaitu: membangun kandang anti harimau, pemeliharaan rusa untuk restocking pakan harimau, restorasi, pembuatan pakan ternak dan pengembangan ekowisata. Metode yang digunakan adalah transfer pengetahuan dan pelibatan masyarakat melalui praktek langsung lapangan. Masyarakat sangat antusias dan pemerintah desa sangat mendukung kegiatan ini, karena dapat memberi solusi langsung terhadap permasalahan masyarakat desa.Kata kunci: Timbang Lawan, Harimau sumatera, penghidupan, konservasi, konflik
