PEMETAAN POTENSI PRODUKSI PADI SAWAH (Oryza sativa L) DENGAN MENGGUNAKAN MODEL SIMULASI TANAMAN DI KABUPATEN MINAHASA SELATAN

Abstract

South Minahasa Regency is one of regencies in the province of North Sulawesi, which had agro-climatic conditions suitable for the growth of rice plants. To determine the growth and development of the rice crop in the South Minahasa District, with various agro-climatic conditions can be simulated models of rice plants. This study aims to determine the potential for rice production in South Minahasa Regency and mapping potential for rice production in South Minahasa Regency. This research was conducted through the collection of climate data (solar radiation, air temperature, air humidity, while irradiation and precipitation) and the data on latitude and longitude coordinates. Implementation using simulation models of rice plants Rice Shierary V.2.1 to determine the potential of rice production and rice production potential mapping in South Minahasa district to use Photo Satellite Imagery processed through ArcView 3.3 software. Research results show the potential of rice production is the village Popontolen 6.11 ton ha-1, village Pakuweru 5.73 ton ha-1, and the Village Karowa 9.00 ton ha-1, the highest production potential are among the sites that Karowa Village 9.00 ton ha-1 is due to have the most ideal temperature for growth and development of paddy rice at an average of 23.12 ° C, and the average rainfall is 293.50 mm and 103.42 mm evapotranspiration. Data from the study indicate the potential for a higher yield than the data Provitas paddy rice official South Minahasa District of 2010-2014. This shows that the achievement of rice production in the district south minahasa not optimal. Hopefully the results of this study be input for agencies involved in this case the Department of Agriculture and Livestock South Minahasa regency in optimizing rice production with activities touching the supporting factors of production such as the provision of improved seed, fertilizer use impartial, repair dams and irrigation networks as well as the use of tools and agricultural machinery so as to increase farmers' income.
