Evaluasi Mutu Fisik Bibit Manglid (Manglietia glauca Bl.) Siap Tanam di Persemaian BPDAS Citarum-Ciliwung, Rumpin.

Abstract

Mutu fisik bibit berpengaruh terhadap pertumbuhan bibit di lapangan. Penilaian mutu fisik bibit manglid harus mengacu pada standar yang ditetapkan. Penelitian ini bertujuan mengevaluasi proses produksi dan menganalisis mutu fisik bibit manglid yang di produksi oleh Persemaian Rumpin. Penilaian mutu bibit manglid dilakukan berdasarkan SNI 8420:2018 tentang Bibit Tanaman Hutan, yang mencakup penetapan jumlah sampel bibit, evaluasi persyaratan umum, dan persyaratan khusus. Bibit dinyatakan lulus uji jika nilai persyaratan umum >95% dan persyaratan khusus >90%. Proses produksi bibit manglid, mulai dari penyiapan media tanam hingga tahap pemeliharaan yang mencakup penyiraman, pemupukan, serta pengendalian hama dan penyakit telah dilakukan dengan baik. Hasil pengujian menunjukkan 97% bibit manglid memenuhi persyaratan umum, melampaui batas minimal >95%. Ciri-ciri tersebut mencakup asal-usul benih yang jelas, batang lurus dan tunggal, kondisi sehat, dan batang berkayu >50%. Rata-rata persyaratan khusus sebesar 95,25%, menunjukkan mutu bibit yang telah memenuhi standar berdasarkan peubah tinggi, diameter, jumlah daun, dan kekompakan media. Secara umum, bibit manglid yang diproduksi oleh Persemaian Rumpin sudah mempunyai mutu fisik sesuai SNI 8420:2018.

The physical quality of seedling is a critical factor influencing field performance, particularly in forest development and land rehabilitation program. The assessment of the physical quality of Manglietia glauca seedlings must refer to established standards. This study evaluated the production process and physical quality of M. glauca seedlings produced at the BPDAS Citarum-Ciliwung Nursery, Rumpin. The assessment followed the Indonesian National Standard (SNI 8420:2018) for forest plant seedling, covering sample size determination, general requirements, and specific criteria. Seedling are considered to meet the standard if general requirements >95% and specific requirements >90%. The production process from media preparation to maintenance including watering, fertilization, and pest and disease control was properly implemented. Result showed that 97% of seedlings met the general requirements including verified seed source, straight and single stem, healthy appearance, and woody stems >50%. The average score for specific criteria was 95,25%, based on height, diameter, number of leaves, and media compactness. In general, M. glauca seedlings from Rumpin Nursery met the physical quality standards as specific in SNI 8420:2018.
