Abstract

Abstrak. Indonesia adalah negara agraris yang mayoritas masyarakatnya adalah petani. Padi merupakan salah satu komoditas pertanian terbesar di Indonesia. Menurut Badan Pusat Statistika pada tahun 2024, produksi beras mengalami penurunan dari 31,10 juta ton menjadi 30,34 juta ton. Penurunan produktivitas beras dapat di sebabkan oleh kualitas benih yang digunakan. Benih yang umur simpanya melebihi 6 bulan akan meningkatkan deteriosasi yang membuat vigor dan viabilitas menurun. Vigor dan viabilitas benih yang menurun dapat diatasi dengan memberikan perlakuan invigorasi seperti paparan medan magnet. Penelitian ini dilakukan di tiga tempat berbeda dari bulan Juli hingga Oktober 2024. Tujuan penelitian ini untuk mengkaji paparan medan magnet Extremely Low Frequency (ELF) dengan intensitas 0,2 miliTesla (mT) terhadap perkembangan generatif tanaman padi yang berasal dari benih tua. Pada penelitian ini menggunakan metode RAL dengan 4 perlakuan berbeda P0 (Kontrol), P1 (3 menit 54 detik), P2 (7 menit 48 detik), dan P3 (11 menit 42 detik). Tinggi tanaman, jumlah anakan produktif dan tidak produktif, panjang malai, jumlah buku per malai, jumlah cabang primer pada malai dan jumlah cabang sekunder pada malai, dan berat gabah 100 butir merupakan parameter pengamatan pada penelitian ini. Hasil menunjukkan bahwa panjang malai, jumlah buku per malai, dan jumlah cabang sekunder semuanya memiliki pengaruh signifikan. Jumlah buku per malai dapat meningkat pada fase perkembangan generatif jika dipapar medan magnet dengan durasi 3 menit 54 detik.Abstract. Indonesia is an agrarian country where the majority of the population are farmers. Rice is one of the largest agricultural commodities in Indonesia. According to the Central Bureau of Statistics in 2024, rice production declined from 31.10 million tons to 30.34 million tons. This decline in rice productivity can be attributed to the quality of seeds used. Seeds stored for more than six months experience deterioration, leading to reduced vigor and viability. Reduced seed vigor and viability can be improved through invigorating treatments such as exposure to a magnetic field. This study was conducted in three different locations from July to October 2024. The objective of the research was to examine the effect of Extremely Low Frequency (ELF) magnetic field exposure with an intensity of 0.2 milliTesla (mT) on the generative growth of rice plants derived from aged seeds. The study used a Completely Randomized Design (CRD) method with four different treatments: P0 (Control), P1 (3 minutes 54 seconds), P2 (7 minutes 48 seconds), and P3 (11 minutes 42 seconds). The observed parameters included plant height, number of productive and non-productive tillers, panicle length, number of nodes per panicle, number of primary branches on the panicle, number of secondary branches on the panicle, and the weight of 100 grains. The results showed that panicle length, number of nodes per panicle, and number of secondary branches were all significantly affected. The number of nodes per panicle increased during the generative growth phase when exposed to a magnetic field for 3 minutes and 54 seconds. Keywords: aged seeds, Extremely Low Frequency (ELF), generative, rice.Abstract. Indonesia is an agrarian country where the majority of the population are farmers.
