Kesesuaian Hidroklimat Padi Pandanwangi (Kasus Kabupaten Cianjur

Abstract

The study of hydro-climate in this research is as new assessment of crop plants cultivation requirement, which is an aromatic rice paddy variety of Pandanwangi Cianjur (Pare Ageung). The study aims to: 1) identification correlation behind of hydro-climate and Pandanwangi rice paddy cultivation; 2) assess criteria of hydro-climate suitability for Pandanwangi rice paddy cultivation; 3) assess the impact of hydro-climate to social aspect of pandanwangi cultivation activity in Cianjur. Retrieval of data and information in the form of (i) literature review and (ii) field surveys: includes interviews to Pandanwangi farmers with documentation. The results showed that: 1) hydro-climate can influence to Pandanwangi cultivation activity: some hydro-climate parameters: land position at watershed, type of reservoir, and temporal characteristic of water depth (irrigation) can influence to Pandanwangi cultivation area size; 2) criteria of hydro-climate suitability for Pandanwangi rice paddy cultivation, consisting of: i) Temperature-elevation variation: Pandanwangi paddy field area must at temperature 22-24oC at elevation 500-800 meters above sea level (more cooler 2-3oC and more height) than general paddy field in low land at temperature 26-27oC and elevation less than 250 meters above sea level; ii) Koppen classification: Af (humid tropic); iii) land position at watershed: upper course of watershed with natural irrigation reservoir; and iv) characteristic of water depth: irrigation must available continually/continuously in 160 days flooded in a one time planting period of 180 days; 3) hydro-climate can make the suitable environment for cultivation being limited, so the original product of pandanwangi rice at market are limited to. This is can be good or bad impact for social aspect. The government's of Cianjur must efforts cultivation activities of this variety to increase it. One of the way to do it is by certification of the ric
