| Judul Artikel | APLIKASI SINAR GAMMA Co-60 TERHADAP KARAKTER ANATOMI DAN MORFOLOGI PADI HITAM (Oryza sativa L. var. indica) SIRAMPOG, BREBES |
| Abstrak (Bhs. Indonesia) | Padi hitam (Oryza sativa L. var. indica) Sirampog, Brebes merupakan salah satu varietas padi yang ada di Indonesia dan termasuk padi lokal dan memiliki karakter utama dengan bijinya yang berwarna kehitaman. Padi hitam mengandung pigmen antosianin yang paling baik dibandingkan jenis padi lain. Budidaya padi hitam masih jarang dilakukan karena sosok tanaman yang tinggi sehingga mudah rebah, memiliki periode umur panen panjang, dan produktivitasnya rendah. Tujuan penelitian ini adalah untuk mengetahui karakter anatomi dan morfologi padi hitam Sirampog, Brebes dengan pengaplikasian sinar gamma Co-60. Perlakuan radiasi sinar gamma Co-60 dilakukan pada benih padi sebelum ditanam. Perlakuan dilakukan menggunakan 4 taraf yaitu 0 Gy, 100 Gy, 200 Gy, dan 300 Gy. Masing-masing dengan ulangan 5 kali, sehingga terdapat 20 unit percobaan. Variabel yang diamati meliputi variabel terikat yaitu karakter anatomi dan morfologi padi hitam Varietas Sirampog, Brebes, sedangkan variabel bebasnya adalah konsentrasi radiasi sinar gamma Co-60. Parameter yang diamati meliputi karakter anatomi yang terdiri dari tebal kutikula, tebal mesofil, panjang dan lebar stomata daun, kerapatan stomata dan trikomata per 1 mm2 luas daun, serta karakter morfologi meliputi tinggi tanaman, lebar daun dan diameter calmus. Berdasarkan hasil pengamatan diperoleh bahwa aplikasi sinar gamma Co-60 berpengaruh terhadap karakter anatomi daun padi hitam Sirampog, Brebes yaitu meningkatkan tebal kutikula, panjang dan lebar stomata, kerapatan stomata, dan kerapatan trikomata, tetapi menurunkan tebal mesofil pada dosis 300 Gy. Aplikasi sinar gamma Co-60 juga menyebabkan perubahan karakter morfologi tanaman padi hitam, yaitu dengan menurunnya ukuran tinggi tanaman, lebar daun, dan diameter calmus pada dosis 300 Gy. |
| Abtrak (Bhs. Inggris) | Black rice (Oryza sativa L. var. indica) Sirampog, Brebes variety is one of the rice varieties in Indonesia. Black rice contains the best anthocyanin pigments compared to other types of rice. Black rice cultivation is rarely done because black rice has a tall plant figure so it is easy to fall, has a long harvest life, and low productivity. The aim of this study is to determine the anatomical and morphological characteristics of black rice Sirampog, Brebes with the applications of Co-60 gamma rays. Radiation treatment was carried out on rice seeds before planting. The treatment was carried out using 4 levels, namely 0 Gy, 100 Gy, 200 Gy, and 300 Gy. Each treatment was repeated 5 times, so there were 20 experimental units. The dependent variable observed is the anatomical and morphological characteristics of black rice Sirampog variety, Brebes, while the independent variable was the concentration of Co-60 gamma ray radiation. Parameters observed included anatomical characters, namely cuticle thickness, mesophyll thickness, the length and width of stomata, the density of stomata and trichomes per 1 mm2 leaf area, and morphological characters, namely plant height, leaf width, and stem diameter. The data obtained were analyzed using ANOVA and the results were continued with LSD test with a 95% confidence level. The results obtained were the application of gamma rays Co-60 affects the anatomical character of black rice leaves, namely by increasing cuticle thickness, the length and width of stomata, stomata density, and trichome density, but decreasing mesophyll thickness at a dose of 300 Gy. The application of Co-60 gamma rays can also cause changes in the morphology of black rice plants, namely decreasing plant height, leaf width, and calmus diameter at a dose of 300 Gy. |
