Muttaqien, Khaerul (2017) Evaluasi Dampak Sistem Pengelolaan Air Pada Budidaya Padi (Oryza sativa L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Tanaman padi (Oryza sativa L.) merupakan tanaman pangan penting yang telah menjadi makanan pokok lebih dari setengah penduduk dunia, oleh karena itu setiap faktor yang mempengaruhi peningkatan produksi dan penurunan produksi padi sawah akibat dampak lingkungan sangat penting untuk diperhatikan. Pada produksi padi di tahun 2015 sebanyak 75,36 juta ton gabah kering giling (GKG) atau mengalami kenaikan sebanyak 4,51 juta ton (6,37 persen) dibandingkan tahun 2014. Kenaikan produksi tersebut terjadi di Pulau Jawa sebanyak 2,31 juta ton dan di luar Pulau Jawa sebanyak 2,21 juta ton (BPS, 2016). Kegiatan penelitian dilaksanakan pada bulan Agustus 2016 sampai Januari 2017. Pelaksanaan penelitian dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Brawijaya yang terletak di Jalan Kembang Kertas Jatimulyo Malang, Jawa Timur. Alat yang digunakan dalam penelitian ini meliputi cangkul, sabit, papan label, penggaris, meteran, timbangan, gelas ukur, thermohygrometer, alat tulis, kamera digital, sprayer, jaring, bambu dan ember (pot). Sedangkan bahan yang digunakan adalah benih tanaman padi varietas Inpari 30, Insektisida, Urea, SP-36 dan KCl. Metode penelitian yang akan digunakan adalah metode Rancangan Acak Kelompok (RAK) Metode analisis rancangan acak kelompok dan untuk mengetahui perbedaan antara perlakuan dilakukan pengujian dengan uji BNT 0,05. Perlakuan S1: Sistem penggenangan terus-menerus 5 cm; S2: Sistem penggenangan terus-menerus 3 cm; S3: Sistem penggenangan setinggi permukaan tanah (macak-macak); S4: Sistem penggenangan 5 cm secara terputus-putus setiap 1 minggu sekali dan 1 minggu dikeringkan; S5: Sistem penggenangan 5 cm secara terputus-putus setiap 2 minggu sekali dan 2 minggu dikeringkan; S6: Sistem penggenangan 5 cm secara terputus-putus setiap 3 minggu sekali dan 1 minggu dikeringkan; S7: Sistem penggenangan 3 cm secara terputus-putus setiap 1 minggu sekali dan 1 minggu dikeringkan; S8: Sistem penggenangan 3 cm secara terputus-putus setiap 2 minggu sekali dan 2 minggu dikeringkan; S9: Sistem penggenangan 3 cm secara terputus-putus setiap 3 minggu sekali dan 1 minggu dikeringkan; S10: Pengusahaan padi lahan secara kering/Kapasitas Lapang. Hasil penelitian menunjukkan bahwa semua sistem pengelolaan air yang tergenang (0 cm sampai 5 cm) tidak begitu berbeda terhadap hasil dan pertumbuhan tanaman padi. Namun pada keadaan kapasitas lapang tanaman padi mengalami penurunan pertumbuhan dan hasil bila dibandingkan dengan sistem ii penggenangan terus-menerus, terputus-putus dan macak-macak. Penggenangan air terptus-putus mendapatkan nilai lebih baik dari pada sistem genangan terus-menerus, macak-macak dan kapasitas lapang dimana sistem penggenangan 5 cm terputus-putus 3 minggu tergenang dan 1 minggu dikeringkan mendapatkan nilai pertumbuhan lebih baik pada tinggi tanaman, jumlah anakan dan luas daun. Sistem pengelolaan air S6 mendapatkan hasil gabah kering panen pot per gram lebih baik yaitu sebesar 103,54 g pot-1 dibandingkan S1, S2, S3 dan S10 yang mendapatkan nilai sebesar 81,40 g pot-1, 82,31 g pot-1, 76,85 g pot-1 dan 30,50 g pot-1.
English Abstract
Rice (Oryza sativa L.) is an important food plants that have become the staple food of more than half of the world's population. There for every factors that affects the increase and the decrease in rice production due to the impact of the environment is very important to note. In 2015 the production of rice reached 75,36 million ton, increased as much as 4,51 million ton (6,37 %) than in 2014. That increase in Java as much as 2,31 million ton and out of java as much as 2,21 million ton (BPS, 2016). The research activity was implemented during August 2016 until January 2017. The experiment was conducted at the experimental garden of Agriculture Faculty of Brawijaya University which is located at kembang kertas street, Jatimulyo, Malang East Java. The tool used on that research includes hoe, crescent, label board, ruler, meter, the scales, measure glass, thermohygrometer, stationery, digital camera, sprayer, net, bamboo, and bucket (pot). While the material used are the rice seed Inpari 30 Variety, Insecticide, Urea, SP-36 and KC1. The research method is Random Design Group, the analysis method is Randomized Blok Design, and to know the difference between the treatment is by LSD 0,05. S1 Treatment: inundation system continuously 5 cm; S2: inundation system continuously 3 cm ; S3 inundation system as high as the soil surface; S4 inundation system discontinuously every 1 week and other 1 week dried; S5: inundation system 5 cm discontinuously every 2 weeks and week dried; S6: inundation system 5 cm discontinuously every 3 weeks and 1 week dried; S7: inundation system 3 cm discontinuously every 1 week and 1week dried; S8: inundation system 3 cm discontinuously every 2 weeks and 2 weeks dried; S9: inundation system 3 cm discontinuously every 3 weeks and 1 week dried; S10: The cultivation of rice in dry soil/ field capacity. The result of research shows that all inundated water management systems (0 cm to 5 cm) do not show big differences to the result and growth of rice. But at the deal capacity condition, the result and growth of rice is decrease than the continuous inundation, discontinuous and average system. The water inundation discontinuously get better result than the continuous inundation, average and deal capacity system. By 5 cm inundation model discontinuously 3 weeks inundation and 1 weeks dried get better growth result from the height of plant, amount of tillers and the wide of leave. S6 water management system gets better result by iv total grain weight harvest pots per gram as much 103,54 g pot-1 compared with S1, S2, S3 and S10 which get result as much 81,40 g pot-1, 82,31 g pot-1, 76,85 g pot-1 and 30,50 g pot-1.
