Agriculture land suitability of tidal swampy area at Palingkau Irrigation Area in Central Kalimantan Province for national food estate program

Abstract

Agriculture plays an important role in Indonesia development. Between the years 2020 - 2024, the government targets food security on sustainable development goals. Food estates have been made in several areas. However, there are constraints such as peatland and low elevation. Various irrigation systems developed by inhabitants and government called Handil, the traditional water management system applied to irrigate rice fields using tidal river system. One of the Handil in Central Kalimantan is called Handil Rakyat Palingkau in Kapuas which can control irrigation area for around 1397 ha. Agricultural land suitability analysis is needed to ensure land suitability based on land quality in requirements and planning. In this study, land analysis was determined using FAO parameters which were analyzed based on temperature, soil type, soil nutrient retention, hydro-topography, safe from flooding, and water quality. The results showed that the relevant aspects for rice were salinity, peat thickness, inundation, TDS, pyrite depth, and hydro topography. However, some aspects are unsuitable for rice that need more attention, such as pH, temperature, and soil nutrient retention.
