Abstract

Hasil observasi mengemukakan bahwa sebagian besar masyarakat Dusun Sumber Gadung memanfaatkan tumbuhan sebagai obat untuk menyembuhkan berbagai jenis penyakit. Alasan untuk menjelaskan hal tersebut adalah tumbuhan obat mudah dijangkau baik harga maupun ketersediaannya, selain dinilai sangat ampuh menyembuhkan penyakit. Tujuan penelitian adalah mengidentifikasi jenis tumbuhan obat yang digunakan oleh masyarakat Dusun Sumber Gadung, Desa Slateng, Kecamatan Ledokombo Kabupaten Jember, Provinsi Jawa Timur. Metode penelitian yang dipakai adalah metode deskriptif dengan teknik penentuan sampel secara Purposive Sampling. Teknik pengkoleksian data dikerjakan dengan teknik observasi, eksplorasi, koleksi serta dokumentasi. Waktu penelitian dilaksanakan di bulan Oktober sampai bulan Desember 2022, sedangkan tempat riset berada di Dsn. Sumber Gadung Ds. Slateng Kec. Ledokombo Kab. Jember. Hasil identififikasi jenis tumbuhan obat yang terdapat di daerah Dusun Sumber Gadung dan masih digunakan sebagai pengobatan tradisional adalah berjumlah 40 macam tumbuhan obat. Tumbuhan tumbuhan obat tersebut tersebar dalam golongan 25 famili dengan golongan famili terbanyak adalah famili Asteraceae ( 7 jenis tumbuhan obat). Bagian tumbuhan yang paling banyak digunakan adalah bagian daun (65 %). Kata kunci: Obat Herbal, Pengobatan Tradisional, Tumbuhan Obat.

Abstract

This study investigates the phenotypic alterations in Dendrobium 'Transient White Rika' (RKA) and 'Florenza' (FLO) orchids resulting from colchicine-induced polyploidy during in vitro cultivation. Colchicine, a known mitotic inhibitor, was applied at varying concentrations (0 ppm, 4000 ppm, 5000 ppm, 6000 ppm) to induce chromosome doubling and assess its impact on the vegetative and generative phases of the orchids. A factorial Randomized Block Design (RBD) was employed to analyze the effects of these treatments. The study revealed significant variations in leaf length and color, particularly at higher colchicine concentrations. Morphological changes were most pronounced at 6000 ppm, where the leaf length decreased, and flower morphology exhibited unique features compared to the control. The study also observed a reduction in stomatal density as colchicine concentration increased, correlating with an enlargement of leaf epidermal cells. These findings indicate that colchicine treatment can effectively induce phenotypic changes in Dendrobium orchids, contributing to the development of hybrids with superior ornamental qualities. However, the study also notes that the response to colchicine is variable, with certain parameters like the number of new shoots and leaf width not showing significant changes. The results underscore the potential of colchicine-induced polyploidy in orchid breeding, though further research is necessary to optimize treatment protocols and ensure the stability and viability of the resulting hybrids. These findings may serve as valuable material for genetics-based learning modules in biology.
