Penelitian Pengaruh Penggunaan Media Tanam Berbasis Sarang Rayap Subfamili Termitinae dari Stasiun Penelitian Soraya Terhadap Pertumbuhan Tanaman Nilam Aceh (Pogostemon cablin) telah dilaksanakan pada April-Juli 2025. Penelitian ini bertujuan untuk mengidentifikasi genus rayap pada sarang rayap yang dikoleksi, menganalisis kandungan unsur hara serta menentukan pengaruh media tanam berbasis sarang rayap subfamili terhadap pertumbuhan tanaman nilam Aceh varietas Sidikalang. Metode yang digunakan adalah Metode Eksperimental dengan Rancangan Acak Lengkap (RAL) dengan faktor variasi dosis sarang rayap. Lima perlakuan dosis sarang rayap yaitu D0 (0%), D1 (25%), D2 (50%), D3 (75%), dan D4 (100%). Setiap perlakuan dilakukan 5 ulangan, sehingga terdapat 25 unit percobaan. Parameter yang diamati berupa kandungan unsur hara, tinggi tanaman, diameter batang, panjang dan lebar helaian daun, serta jumlah cabang. Hasil menunjukkan genus yang ditemukan terdiri dari 2 spesies Pericapritermes dan 5 spesies Dicuspiditermes. Penambahan sarang rayap meningkatkan kandungan unsur hara seperti karbon organik, nitrogen total, fosfor, kalium. Penurunan pH terjadi seiring bertambahnya dosis. Hasil analisis uji statistik (ANOVA) dapat diketahui bahwa dari nilai rata-rata bahwa perbedaan perlakuan dosis sarang rayap pada media tanam terhadap pertumbuhan nilam Aceh varietas Sidikalang tidak menunjukkan pengaruh yang signifikan. Namun, secara numerik terlihat adanya peningkatan pada perlakuan dengan penambahan sarang rayap khususnya pada D1 dan D2. Hasil penelitian ini menunjukkan bahwa penggunaan sarang rayap dari subfamili Termitinae berpotensi sebagai bahan organik alternatif dalam media tanam, karena mengandung unsur hara penting, meningkatkan kualitas tanah, dan menunjukkan kecenderungan positif terhadap pertumbuhan tanaman nilam Aceh.

ABSTRACT The study of the Effect of Using Termite Nest-Based Planting Media of the Subfamily Termitinae from the Soraya Research Station on the Growth of Aceh Patchouli Plants (Pogostemon cablin) was conducted in April-July 2025. This study aims to identify the termite genus in the collected termite nests, analyze the nutrient content and determine the effect of the termite nest-based planting media of the subfamily on the growth of Sidikal Aceh patchouli of the Sidikalang variety. The method used is the Experimental Method with a Completely Randomized Design (CRD) with a variation factor of the termite nest dose. Five termite nest dose treatments are D0 (0%), D1 (25%), D2 (50%), D3 (75%), and D4 (100%). Each treatment was repeated 5 times, resulting in 25 experimental units. The parameters observed were nutrient content, plant height, stem diameter, leaf blade length and width, and number of branches. The results showed that the genus found consisted of 2 species of Pericapritermes and 5 species of Dicuspiditermes. The addition of termite nests increases the content of nutrients such as organic carbon, total nitrogen, phosphorus, and potassium. A decrease in pH occurs as the dose increases. The results of the statistical analysis (ANOVA) show that the average value of the difference in the dose of termite nests in the planting medium on the growth of Aceh patchouli of the Sidikalang variety does not show a significant effect. However, numerically, there is an increase in the treatment with the addition of termite nests, especially in D1 and D2. The results of this study indicate that the use of termite nests from the Termitinae subfamily has the potential as an alternative organic material in planting media, because it contains important nutrients, improves soil quality, and shows a positive trend towards Aceh patchouli plant growth.
