Pendugaan Tingkat Produktivitas Pertanian Lahan Kering dengan Metode Indeks Storie di Kecamatan Raya Kabupaten Simalungun
Abstrak
The aimed of this research was to find out the level of agricultural land productivity at Raya
SimalungunSubdistrict with Storie Index Method. This research had been done since March–May 2014
at Raya Simalungun Subdistrict. Sampling spot was done at the certain agricultural landused, slope,
and types of soil. Land use types consist of dry land agriculture and plantation. The slopes consisted of
land with vary on declivity; 2-15%, 15-25%, 25-40% and >40%, meanwhile the soil’s types include
Tropaquepts, Dystrandepts, Haplorthox, Tropudults, Hydrandepts. The result of agriculture land based
on several factors; dynamic factor of land such as drainage, erossion, pH, Electric Conductivity (EC) of
soil layer, showed that the level of productivity of agricultural land in Raya Simalungun Subdistrict is
Excellent Quality, Moderate, Poor and Very Poor. The most extensive land quality is at Grade 3 or
Medium quality is amounted to 21,109.85 Ha or 88.65% of the area of dry land agriculture. Area of
productive dry land agriculture in Raya Simalungun Subdistrict is 22,059.40 Ha or 92,63% and less
productive land area is 1,754 Ha or 7.37 of area dry land agriculture.
Key words: Productivity of agricultural land, storie index, texture, landuse, drainage, erossion, pH,
Electric Conductivity (EC).
