Abstract

ABSTRACT Geographically, South Minahasa district lies between 1 ° 17'18.22 "north latitude and 124 ° 54'48.84" east longitude, with a total area is 1188.67 km2, or approximately 8% of the total area of North Sulawesi (15.069.00 km2 ), with the coast in the north and south and the high plains, where irrigated rice fields provide an abundant harvest.
