Abstract

Land suitability is one method used to assess the suitability of a commodity to be cultivated sustainably on land. This research aimed to highlight the issue of agricultural land for maize in Kulah Hilir District, Labuhan Batu Regency, North Sumatra. The method used in this research is the matching evaluation method (weight factor match). The data used in this research is secondary data sourced from research data in the form of rice agricultural land suitability data with the title Evaluation of Land Suitability for Rice (Oryza sativa L.) in Kualuh Hilir District, Labuhanbatu Regency. North, North Sumatra. This research showed that the land suitability class of corn in Kualuh Hilir District, North Labuhanbatu Regency, North Sumatra, using the weight factor matching method, is in class S2, "quite suitable" for planting corn plants. There are two limiting factors in land adjustment from rice plant data for corn plants; namely, the limiting factor for nutrient retention (nr) is only (base saturation (%)) and pH H2O with a land suitability level of "marginal suitability" S3 but improvements can be made to increase the class. The suitability of the land with the addition of organic materials and lime ameliorant materials with low to medium input can increase the potential suitability class of the land to S2.

Abstract

This research aims to identify the factors causing the water crisis in Spain, analyze its impact on society and the economy, and evaluate solutions that can be implemented. The research methodology uses library or literature studies and involves secondary data analysis. Key findings show that drought, declining water reserves and climate change are the main factors in Spain's water crisis, which impacts public health, the agricultural sector and social stability. Based on these findings, it is concluded that collaborative measures between government, society and relevant sectors are needed to address this water crisis effectively and sustainably to ensure adequate water availability for Spain in the future.
