Land Suitability Assessment for Lemongrass Cultivation at a University Technopark in Bogor Regency, West Java, Indonesia

Abstract A technopark is currently being developed at the Nagrak Campus of Universitas Trisakti, Bogor Regency, to support university-owned R&D. This university is conducting research on the use of lemongrass ( Cymbopogon citratus ) waste as a material for hygiene products. Given the importance of lemongrass in supporting research innovations at the Universitas Trisakti, the university hopes to integrate a lemongrass cultivation area into a technopark. The study aimed to assess the land suitability of the Nagrak Campus Technopark for lemongrass cultivation. A survey was conducted to assess the land characteristics and collect soil samples, followed by laboratory soil analysis. Land suitability was assessed by comparing the field data with the preferred growing conditions for lemongrass. The results showed that the Nagrak Campus Technopark is marginally suitable for lemongrass cultivation. The major limiting factors are nutrient retention (low base saturation and pH) and nutrient availability (low phosphorus content). Other limiting factors include high temperature, water availability (high rainfall and air humidity), rooting conditions (clay soil texture), and nutrient availability (low total nitrogen). Efforts to enhance land quality and crop production include the addition of agricultural lime and fertilizers to the soil. These efforts may improve land suitability from marginally to moderately suitable conditions.
