EFEKTIFITAS MOLUKISIDA MINYAK SIRIH SIRIH DAN LEMONGGRAS TERHADAP HAMA KEONG MAS PADA TANAMAN PADI

Abstract

ABSTRAK Minat masyarakat Indonesia dalam menggunakan pestisida nabati terus meningkat sehingga perkembangan penelitian mengenai pestisida nabati sangat prospektif, walaupun daya kerja pestisida nabati agak lambat dan memerlukan frekuensi pemberian lebih banyak, namun efeknya lebih baik bagi lingkungan, karena mudah terurai di alam. Untuk itu telah dilakukan penelitian efektifitas molukisida nabati berbahan minyak sirih sirihan dan lemongrass terhadap hama keong mas tanaman padi. Penelitian disusun dalam bentuk Rancangan Acak Kelompok dengan 7 perlakuan dan 8 ulangan masing-masing perlakuan terdiri dari 15 ekor keong mas dengan berat relatif sama. Perlakuan tersebut adalah 1). minyak sirih-sirihan kosentrasi 165 ppm, 2). minyak sirih-sirihan kosentrasi 325 ppm, 3). minyak sirih-sirihan kosentrasi 625 ppm, 4). minyak lemongrass kosentrasi 165 ppm 5). minyak lemongrass kosentrasi 325 ppm, 6). minyak lemongrass kosentrasi 625 ppm dan 7). Sebagai pembanding minyak kayu manis kosentrasi 625 ppm, dengan lama waktu perendaman 24 jam. Hasil penelitian menunjukkan bahwa molukisida nabati minyak sirih sirihan pada kosentrasi 325 ppm mampu menghambat makan keong mas dan menyebabkan kematian mencapai 100%, dan juga dapat meningkatkan pertumbuhan vegetatif dari tanaman padi. Dari hasil penelitian ini diharapkan dengan menggunakan molukisida nabati, tidak saja dapat mengendalikan serangan hama keong mas akan tetapi juga dapat meningkatkan produksi dari tanaman padi, serta menambah nilai tanaman liar menjadi tanaman yang bernilai ekonomis. ABSTRACT The interest of Indonesian people in using plant pesticides continues to increase so that the development of research on plant pesticides is very prospective, although the working power of plant pesticides is rather slow and requires more frequent administration intervals, but the effect is better for the environment. Besides botanical pesticides also have the advantage of being easily decomposed. For this reason, tests have been carried out on botanical molucicide made from spiked piper oil and lemongrass against golden apple snail pest with a randomized block design that is 7 treatments with 8 replications each treatment of 15 golden apple snails with the same relative weight. The treatment is 1). spiked piper oil concentration of 165 ppm, 2). spiked piper oil concentration 325 ppm, 3). spiked piper oil, concentration 625 ppm, 4). concentrated lemongrass oil 165 ppm 5). concentration of 325 ppm lemongrass oil, 6). Lemongrass oil concentration of 625 ppm and 7). As a comparison of cinnamon oil concentration of 625 ppm, with a soaking time of 24 hours. The results showed that botanical spiked piper oil molucides at a concentration of 325 ppm were able to inhibit the eating of golden apple snails and cause mortality to reach 100%, and also could increase the vegetative growth of rice plants. golden apple snail pests, but can also increase production from rice plants, and increase the value of wild plants into economically valuable plants.
