Nilam Aceh merupakan jenis nilam yang paling banyak dibudidayakan di Indonesia karena memiliki kualitas sangat tinggi dan banyak diminati oleh pasar dunia. Tanaman nilam dibudidayakan secara vegetatif dengan teknik setek. Keberhasilan teknik setek dipengaruhi oleh pertumbuhan akar. Upaya dalam mempercepat pertumbuhan akar yaitu dengan menggunakan zat pengatur tumbuh. Salah satu zat pengatur tumbuh yang dapat diberikan pada setek nilam untuk merangsang pertumbuhan akar yaitu ekstrak bawang merah. Tujuan penelitian ini untuk mengetahui pengaruh konsentrasi, lama perendaman dalam ekstrak bawang merah serta mengetahui adanya interaksi antara konsentrasi dan lama perendaman ekstrak bawang merah terhadap setek nilam Aceh. Penelitian ini dilaksanakan di Desa Lampuuk Kecamatan Darussalam Kabupaten Aceh Besar yang terletak pada ketinggian 4,7 mdpl dengan titik koordinat 5o33’57”N, 95o23’12”E dan Laboratorium Ilmu dan Teknologi Benih Fakultas Pertanian Universitas Syiah Kuala. Penelitian ini berlangsung pada bulan Februari – Juli 2024. Penelitian ini menggunakan rancangan acak kelompok pola faktorial 4×3 dengan 3 kali ulangan. Faktor yang diteliti yaitu 4 taraf konsentrasi ekstrak bawang merah (30, 45, 60, dan 75%) dan 3 taraf lama perendaman (60, 120, dan 180 menit). Hasil penelitian ini menunjukkan bahwa perlakuan berbagai konsentrasi berpengaruh sangat nyata terhadap jumlah daun umur 45 HSPT dan jumlah cabang umur 15 HSPT, berpengaruh nyata terhadap tinggi tanaman dan jumlah daun umur 60 HSPT, dan jumlah cabang umur 0, 45 dan 60 HSPT. Pertumbuhan setek nilam Aceh terbaik dijumpai pada konsentrasi 75%. Lama perendaman setek nilam dalam ekstrak bawang merah berpengaruh nyata terhadap jumlah daun umur 30 HSPT dan jumlah cabang umur 0 HSPT. Pertumbuhan setek nilam Aceh terbaik dijumpai pada lama perendaman 120 menit. Interaksi yang nyata antara konsentrasi dan lama perendaman ekstrak bawang merah terhadap tinggi tanaman umur 60 HSPT, jumlah daun umur 45 dan 60 HSPT. Pertumbuhan tinggi tanaman dan jumlah daun terbaik terdapat pada kombinasi perlakuan konsentrasi 75% dan lama perendaman 120 menit.

Aceh Patchouli is a type of patchouli that is most widely cultivated in Indonesia due to its high quality and high demand in the global market. Patchouli plants are cultivated vegetatively using the stem cutting technique. The success of this technique is influenced by root growth. Efforts to accelerate root growth include the use of growth regulators. One growth regulator that can be given to patchouli stem cuttings to stimulate root growth is red onion extract. The purpose of this study is to determine the effect of concentration, soaking time in red onion extract, and the interaction between concentration and soaking time on Aceh patchouli stem cuttings. This research was conducted in Lampuuk Village, Darussalam District, Aceh Besar Regency, which is located at an altitude of 4.7 meters above sea level with coordinates 5°33'57" N, 95°23'12" E, and at the Seed Science and Technology Laboratory, Faculty of Agriculture, Syiah Kuala University. The research was carried out from February to July 2024. This study used a 4x3 factorial randomized complete block design with three replications. The factors studied were four levels of red onion extract concentration (30, 45, 60, and 75%) and three levels of soaking time (60, 120, and 180 minutes). The results of this study show that the treatment of various concentrations has a very significant effect on the number of leaves at 45 days after planting (HSPT) and the number of branches at 15 HSPT, a significant effect on plant height and the number of leaves at 60 HSPT, and the number of branches at 0, 45, and 60 HSPT. The best growth of Aceh patchouli stem cuttings was found at a concentration of 75%. The soaking time of patchouli stem cuttings in red onion extract has a significant effect on the number of leaves at 30 HSPT and the number of branches at 0 HSPT. The best growth of Aceh patchouli stem cuttings was found at a soaking time of 120 minutes. There is a significant interaction between the concentration and soaking time of red onion extract on plant height at 60 HSPT, the number of leaves at 45 and 60 HSPT. The best growth of plant height and the number of leaves was found in the combination of 75% concentration and 120 minutes soaking time.
