      Abstract
      Inokulasi rizobakteri dan aplikasi ekoenzim diketahui dapat meningkatkan pertumbuhan tanaman. Penelitian ini bertujuan mengkaji potensi rizobakteri dan ekoenzim terhadap pertumbuhan Aquilaria malaccensis Lamk. Penelitian menggunakan rancangan tersarang dengan ekoenzim sebagai anak petak yang tersarang pada inokulasi rizobakteri (Serratia marcecscens, Stenotrophomonas maltophilia, dan campuran S. marcescens + S. maltophilia) sebagai petak utama. Hasil penelitian menunjukkan inokulasi rizobakteri dan aplikasi ekoenzim tidak berpengaruh terhadap tinggi, diameter, jumlah daun baru, berat basah total, berat kering total, dan kadar air bibit. Jumlah tunas baru pada perlakuan inokulasi S. marcescens tanpa ekoenzim meningkat sebesar 112,5% dibandingkan dengan kontrol. Aplikasi ekoenzim pada bibit yang diinokulasi rizobakteri dapat merangsang pertumbuhan akar dan warna daun yang lebih hijau. Nilai nisbah pucuk akar dan indeks mutu bibit gaharu yang dihasilkan dari penelitian ini menunjukkan bibit siap dipindahkan ke lapangan. Hasil penelitian ini dapat digunakan sebagai acuan dalam mengaplikasikan pupuk hayati pada tanaman kehutanan, khususnya pada jenis yang pertumbuhannya lambat.
       
      Rhizobacteria inoculation and ecoenzyme application can improve seeds' growth. This research aims to study the potency of rhizobacteria and ecoenzyme to improve Aquilaria malaccensis Lamk. growth. The experimental design used a nested plot design where ecoenzyme as the sub-plot that nested in rhizobacteria inoculation (Serratia marcecscens, Stenotrophomonas maltophilia, and the mix of S. marcecscens + S. maltophilia) as the main plot. The results showed that rhizobacteria inoculation and ecoenzyme application were no significant impact on improve the plant height, diameter, amount of new leaves, total fresh weight, total dry weight, and plant moisture content. The new shoots on S. marcescens inoculation without ecoenzyme increased 112,5% compared to the control. Application of ecoenzyme to the plants inoculated by rhizobacteria promoted root growth and made the leaves got greener. Shoot root ratio and seedling quality index showed that seeds were ready to transplant in the field. The results of this study can be used as a reference in applying biofertilizers to forestry plants, especially the slow-growing species.
