Abstract
Penggunaan listrik di berbagai bidang kehidupan, menjadikan di sekeliling kita terdapat medan elektromagnetik. Keberadaan medan elektromagnetik tersebut dapat mempengaruhi organisme hidup, diantaranya adalah pemecahan masa dormansi biji pada tumbuhan. Penelitian ini bertujuan untuk menganalisis pengaruh frekuensi medan listrik dan lama paparan terhadap waktu dormansi biji cabe besar, dan menganalisis pengaruh frekuensi medan listrik dan lama paparan terhadap germinalitas biji cabe besar. Frekuensi medan listrik divariasi dari 100 sampai dengan 500 Hz, dan variasi lama paparan waktunya yaitu 30, 60, 90, 120, dan 150 menit. Parameter yang diamati adalah waktu pemecahan dormansi, dan germinasi biji (panjang tunas dan berat kecambah). Penelitian ini menunjukkan frekuensi medan listrik dan lama paparan berpengaruh terhadap waktu dormansi biji cabe besar, makin meningkat frekuensi medan listrik yang diberikan pada biji, maka pemecahan dormansi makin cepat dan lama paparan medan listrik cenderung memperlambat pemecahan dormansi biji cabe besar, makin lama waktu terpapar medan listrik pemecahan dormansi semakin lama, dan frekuensi medan listrik dan lama paparan berpengaruh terhadap germinalitas biji cabe besar. Makin tinggi frekuensi medan listrik yang diberikan pada biji cabe besar, makin panjang tunas dan makin berat kecambah, dan sebaliknya. Makin lama waktu paparan medan listrik panjang tunas cenderung lebih pendek dan berat lebih kecil.
English Abstract
The use of electricity in various fields makes us surround by electromagnetic fields. The existence of electromagnetic fields it self can affect the growth of living organism, which is the period of breakdown seed dormancy in plants. The aim of this study is to analyzing the frequency of the electric field and the length of exposure of large chili seed dormancy time, and analyzing the effect of the electromagnetic field frequencies and the length of exposure against the Germinality of large chili seeds. The frequency of the electric fields is varied from 100 to 500 Hz, and the variation length of time is 30, 60, 90, 120, and 150 minutes. The main parameters are the time of dormancy breakdown, and the Germinality of seed (shoots length and sprout weight). This study contains the frequency of electric field and the length of exposure can affect the dormancy of Large Chili Seed length of time, the greater the frequency of electric fields given to seeds, so the breakdown dormancy is faster and the length of exposure of electric field tend to longer the breakdown of large chili seed dormancy, the longer the length of exposure of electric fields the longer the breakdown of dormancy, and the frequency of the electric field and length of exposure have an effect against the Germinality of large chili seeds. The higher the frequency of the electric field given to large chili seeds, the longer the shoots and the heavier the sprouts, and so is the opposite. The longer the length of exposure of the electric field the length of shoots tend to shorter and the weight is smaller.
