Abstract

The level of land suitability for lowland rice can be determined by conducting a land suitability evaluation. Information related to land suitability classes can be used as a reference in taking appropriate action in managing rice fields so that production targets can be achieved. The aim of this research is to determine the actual land suitability class for lowland rice crops in Suka Maju Village, Malind District, Merauke Regency. This research used a survey method and soil sampling was carried out on two types of land, namely paddy fields and grasslands. Data collection was carried out by direct observation, laboratory analysis and data analysis. The data analysis technique to determine the subclass of land suitability is to match the growing requirements for lowland rice plants with the quality and characteristics of the land according to the Technical Guidelines for Land Evaluation for Agricultural Commodities, 2011 Revised Edition. The results of the research show that the land suitability class for lowland rice plants is on both types of land. (rice fields and grasslands) are classified as marginal suitability class (S3) with the limiting factors being rooting media (rc), nutrient retention (nr) and available nutrients (na). Basically, the limiting factors in this research can be improved by liming, fertilizing and adding organic materials.

Abstract

With increasing concerns regarding water resource management and environmental sustainability, understanding land use change and the hydrological health of watersheds is critical for informed decision-making. This study aimed to explore the effect of land use changes on hydrological health resilience in the Rejoso watershed, East Java, using remote sensing techniques and geographic information system tools to characterize the various land cover types. Landsat ETM 7+ satellite imagery was used to describe land cover classes. Hydrological health indicators such as water transmission, water availability during the dry season, and peak rainfall buffer events were systematically analyzed in relation to land cover change conditions. Regression statistical methods were used to measure the impact of land cover changes on hydrological parameters. The study results showed that the area of forest land in the Rejoso watershed tended to increase from 2011 to 2021; on the other hand, the area of agroforestry land tended to decrease along with the increase in upland land. In general, the hydrological health of the Rejoso watershed is decreasing from year to year. The increase in forest area, agroforestry, settlements, and ponds provides a positive response to the hydrological health of the watershed. On the other hand, the increase in moorland and rice fields has a negative impact on the hydrological health of the watershed.
