Abstract
ABSTRAK Tanaman nyamplung (Calophyllum inophyllum) memiliki potensi besar sebagai bahan baku biodiesel karena kandungan minyak bijinya yang tinggi, mencapai 40-75% berat kering. Selain itu, tanaman ini memiliki manfaat lingkungan, seperti konservasi tanah dan penghijauan pesisir. Media tanam yang tepat dan penambahan bahan organik sangat penting untuk mendukung pertumbuhan. Media seperti top soil, cocopeat, pasir, dan arang sekam sering digunakan untuk meningkatkan kualitas media tanam. Mikroorganisme lokal (MOL) dari bonggol pisang, yang kaya akan nutrisi seperti karbohidrat (66%) dan protein (4,35%), juga berperan sebagai dekomposer alami dapat meningkatkan kesuburan tanah dan mendukung pertumbuhan bibit. Penelitian ini bertujuan untuk menganalisis pengaruh kombinasi media tanam dan MOL bonggol pisang terhadap pertumbuhan bibit nyamplung. Penelitian ini dilakukan selama 4 bulan di Laboraturium Hutan Pendidikan dan Pembibitan dan Laboratorium Teknologi Hasil Hutan (THH) Jurusan Kehutanan Fakultas Pertanian Universitas Jambi, Dengan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari dua faktor. Adapun faktor pertama dalam adalah media tanam (M) yang terdiri dari tiga taraf yaitu: m1 = top soil + pasir (1:1), m2 = top soil + cocopeat (2:1), m3 = top soil + arang sekam (1:1). Faktor kedua Konsentrasi Mikroorganisme Lokal (MOL) Bonggol Pisang (A) terdiri dari tiga taraf yaitu : a1 = Konsentrasi Mikroorganisme Lokal 10% (100ml/I air), a2 = Konsentrasi Mikroorganisme Lokal 20% (200ml/I air), a3 = Konsentrasi Mikroorganisme Lokal 30% (300ml/I air). Variabel yang diamati berupa tinggi bibit, diameter, jumlah daun, berat kering tajuk, berat kering akar, dan rasio pucuk akar. Hasil penelitian ini menunjukkan bahwa pengaruh media tanam m1 (top soil + pasir (1:1)) menghasilkan tinggi bibit, jumlah daun, dan rasio pucuk-akar terbaik. Perlakuan media m3 (top soil + arang sekam) menghasilkan berat kering akar tertinggi. Penggunaan MOL bonggol pisang dengan konsentrasi 30% menghasilkan jumlah daun terbanyak. MOL tidak berpengaruh nyata terhadap tinggi bibit, diameter batang, berat kering tajuk, dan berat kering akar, kemungkinan karena kandungan nutrisi tanah yang sudah tinggi. Interaksi antara media tanam (M) dan mikroorganisme lokal (A) juga menunjukkan tidak berpengaruh nyata terhadap variabel yang diamati. Disarankan untuk menggunakan media tanam top soil + pasir (1:1) dan MOL bonggol pisang dengan konsentrasi 30% untuk perbanyakan bibit nyamplung di masa mendatang. ABSTRACT Nyamplung plants (Calophyllum inophyllum) have great potential as raw materials for biodiesel because of their high seed oil content, reaching 40-75% dry weight. In addition, this plant has environmental benefits, such as soil conservation and coastal greening. The right planting media and the addition of organic materials are very important to support growth. Media such as top soil, cocopeat, sand, and rice husk charcoal are often used to improve the quality of planting media. Local microorganisms (MOL) from banana stumps, which are rich in nutrients such as carbohydrates (66%) and protein (4.35%), also act as natural decomposers that can increase soil fertility and support seedling growth. This study aims to analyze the effect of the combination of planting media and banana stump MOL on the growth of nyamplung seedlings. This study was conducted for 4 months at the Forestry Education and Nursery Laboratory and the Forest Products Technology Laboratory (THH) of the Forestry Department, Faculty of Agriculture, Jambi University, using the Completely Randomized Design (CRD) method consisting of two factors. The first factor is the planting medium (M) which consists of three levels, namely: m1 = top soil + sand (1:1), m2 = top soil + cocopeat (2:1), m3 = top soil + rice husk charcoal (1:1). The second factor, the Concentration of Local Microorganisms (MOL) of Banana Corm (A) consists of three levels, namely: a1 = Concentration of Local Microorganisms 10% (100ml/I of water), a2 = Concentration of Local Microorganisms 20% (200ml/I of water), a3 = Concentration of Local Microorganisms 30% (300ml/I of water). The variables observed were seedling height, diameter, number of leaves, dry weight of the crown, dry weight of the roots, and the ratio of root shoots. The results of this study indicate that the effect of planting media m1 (top soil + sand (1:1)) produces the best seedling height, number of leaves, and the ratio of root shoots. The treatment of media m3 (top soil + rice husk charcoal) produces the highest root dry weight. The use of banana stump MOL with a concentration of 30% produced the largest number of leaves. MOL had no significant effect on seedling height, stem diameter, dry weight of the crown, and dry weight of the roots, possibly due to the high soil nutrient content. The interaction between the planting medium (M) and local microorganisms (A) also showed no significant effect on the observed variables. It is recommended to use topsoil + sand (1:1) planting media and banana stump MOL with a concentration of 30% for nyamplung seedling propagation in the future.
