Analisis Keputusan Alih Fungsi Lahan Kopi menjadi Wortel menggunakan Analytical Hierarchy Process (AHP) di Desa Regaji Kabupaten Karo

Abstract

The conversion of agricultural land use from coffee to carrot cultivation in Regaji Village, Karo Regency, reflects the dynamics of farmers’ decision-making in response to economic, social, and environmental factors. This study aims to analyze the factors influencing land-use conversion decisions and to determine the priority of criteria using the Analytical Hierarchy Process (AHP) method. AHP was chosen because it effec- tively addresses multi-criteria problems in a structured manner through hierarchical modeling, weighting, and consistency testing. Primary data were collected through questionnaires distributed to 30 farmers who have converted their coffee plantations to carrot fields. The results indicate that among the seven criteria analyzed, the three highest priorities are harvest duration (30.02%), farmers’ income (25.12%), and production yield (13.36%). These findings suggest that farmers tend to prioritize faster capital turnover and more stable income potential when selecting horticultural crops. The application of AHP in this study is expected to serve as a reference for more rational agrarian decision-making and to support adaptive and sustainable land-use planning.
