      Abstract
      Kegiatan pertambangan kapur berpotensi memberikan dampak negatif terhadap lingkungan sehingga diperlukan kegiatan reklamasi dan rehabilitasi agar kondisi lahan yang telah rusak dapat kembali sesuai peruntukannya. Canarium commune merupakan salah satu spesies yang dapa digunakan dalam kegiatan revegetasi lahan tambang. Penelitian ini bertujuan untuk mendapatkan dosis yang tepat antara pupuk kandang domba dan asam humat untuk meningkatkan kesuburan tanah dan pertumbuhan bibit kenari. Rancangan yang digunakan dalam percobaan ini adalah rancangan acak lengkap (RAL) pola faktorial dengan 2 faktor. Faktor pertama asam humat (0 g, 2,5 g, dan 5 g) dan faktor kedua pupuk kandang domba (0 g dan 500 g). Parameter yang diamati meliputi diameter, tinggi, berat basah total, berat kering total, nisbah pucuk akar, serta kesuburan tanah. Hasil penelitian menunjukkan asam humat berpengaruh nyata terhadap diameter dan pupuk kandang domba berpengaruh nyata terhadap berat basah total, sedangkan kombinasi asam humat dan pupuk kandang domba tidak berpengaruh nyata terhadap semua parameter. Perlakuan A1 (asam humat 2,5 g) tidak berpengaruh pada peningkatan pertumbuhan bibit kenari dan D1 (pupuk kandang domba 500 g) memberikan pengaruh terbaik terhadap parameter berat basah total bibit kenari.
       
      Limestone mining activities have the potential to cause negative impacts on the environment, reclamation and rehabilitation efforts are necessary to restore the damaged land according to its designated purpose. Canarium commune is one of the species that can be used in mine land revegetation activities. This research aims to determine the appropriate dose of sheep manure and humic acid to improve soil fertility and the growth of canarium seedlings. The experimental design used was a factorial Completely Randomized Design (CRD) with two factors. The first factor the application of humic acid (0 g, 2,5 g, and 5 g), and the second factor the application of sheep manure (0 g and 500 g). The observed parameters included diameter, height, total fresh weight, total dry weight, shoot-root ratio, and soil fertility. The results showed application of humic acid significantly affected diameter, and application of sheep manure significantly affected total fresh weight, where as the combination of humic acid and sheep manure had no significant effect on any parameters. Treatment A1 (2,5 g of humic acid) had no effect on increasing the growth of canarium seedlings, and treatment D1 (500 g of sheep manure) provided the best effect on the total fresh weight parameter of canarium seedlings.
