Abstract

Conventional lowland rice cultivation involves flooding the paddy from planting to close to harvest, and high N fertilization. This practice leads to large amount of methane emissions. We studied the effect of soil water regime control on methane gas emissions and growth of several rice varieties on clayey soil. The experiment was arranged according to Split Plot Design. The main plot was water regime, i.e. continuous flooding (2-cm inundation), and intermittent flooding (flooded 2 cm then allowed to dry until the soil started to cracks). The sub-plots consisted of 3 rice varieties, i.e. Inpari 32, Mekongga, and Cisadane. Together, there were six treatment combinations, repeated 4 times. We measured methane emission, plant height, number of tillers per clump, number of productive tillers, and root volume. We computed analysis of variance, then performed Duncan Multiple Range Test. We found, at 57 and 73 days after planting, continuous flooding resulted in much (statistically) higher methane gas emissions than intermittent flooding (about 2 times greater for both Inpari and Cisadane, and 5 times greater for Mekongga). The two water regimes examined did not result in differences in plant height, number of tillers, productive tillers and root volume of the three varieties, although the flooded treatment tended to slightly give taller plant, more tillers and productive tillers. In conclusion, intermittent flooding significantly suppresses methane emission compared to continuous flooding. However, certain rice variety produces more methane than others. While intermittent flooding reduced methane emission, it did not statistically affect rice growth compared to continuous flooding.

Abstract

Desa Wisata Bonjeruk tidak hanya di dominasi oleh wisatawan manca negara dari Eropa dan Australia, tetapi juga wisataan dari asia timur, khususnya wisatawan Korea selatan, china, dan jepang serta perlu di ketahui tiga negara tersebut sangat mencintai budayanya yang sulit untuk menerima budaya luar. tujuan penelitian ini adalah untuk mengetahui Kondisi Aktual wisatawan yang berkunjung ke Wisata Bonjeruk dan untuk menganalisa apa saja Karakteristik Wisatawan yang berkunjung ke Desa Wisata Bonjeruk. Metode yang digunakan dalam penelitian ini adalah menggunakan pendekatan penelitian kualitatif. Pengumpulan data yang digunakan adalah Wawancara (terstruktur, Wawancara semi terstruktur, Wawancara tidak terstruktur), Dokumentasi. Teknik Analisis Data meliputi: Data collection, Data reduction, Display data, Verifikasi dan penarikan kesimpulan. Hasil penelitian ini adalah Karaktristik wisatawan domestik dibedakan menjadi 5 yaitu, a) berdasarkan jenis kelamin,b) umur, c) pekerjaan, d) tingkat pendidikan dan e) intensitas kunjungan wisatawan domestik. Sedangkan respon wisatawan domestik diantaranya adalah tentang lingkungan di objek wisata, keadaan jalan, Atraksi yang disuguhkan, budaya, aksesbilitas menuju ke objek wisata, fasilitas umum di objek wisata, pemandangan di objek wisata dan keamanan di objek wisata. Kendala wisatawan berdasarkan respon wisatawan domestik terhadap Desa Wisata Bonjeruk , diantaranya adalah Lokasi parkir, aksesbilitas menuju ke objek Desa Wisata Bonjeruk dan keamanan. Kendala tersebut perlu peran aktif Pemerintah beserta Dinas Kebudayaan dan Pariwisata Kabupaten Lombok Tengah
