Land suitability assesment for Coffea arabica on the land overgrowed by Uncaria gambir

Abstract

Aornakan I and Kuta Tinggi villages are villages located in Pak-pak Bharat Regency, North Sumatra Province. Currently, the villagers are planting Uncaria gambir and Coffea arabica. This study aimed to evaluate land for cofffe plantations on land overgrown with gambier in Pak-pak Bharat Regency. Sampling was carried out purposively on land overgrown with gambier plants in Aornakan I Village, Pargetteng-getteng Sengkut Sub-district and Kuta Tinggi Village, Salak Sub-district, Pakpak Bharat Regency. The evaluation of land suitability for coffee uses the matching method, namely by analysing laboratory data and data measured in the field with the characteristics of the land for cofffe. The results showed that the land evaluation for Coffea arabica was marginally suitable (S3) with the limiting factor was the root zone media (rc) in terms of soil texture.

“…Meanwhile, Figure 3 reveals that both Aornakan 1 Village and Kuta Tinggi Village have potential land suitability for S. benzoin of class S2, with the limiting factors being wa and rc. Notably, the average temperature and altitude in these two villages are categorized as S2 (moderately suitable) (Rahmawaty et al 2021c). Previous research in the same villages, Aornakan I Village and Kuta Tinggi Village, indicated that the land was marginally suitable for Coffee arabica cultivation (S3), with the limiting factor being the root medium (rc), particularly soil texture.…”

“…Research about kemenyan was conducted by Rahmawaty et al (2021b;2023a) and gambir (Rauf et al 2015;Rahmawaty et al 2021a;2023b) have demonstrated that both kemenyan and gambir share similar land characteristics across various criteria. These findings suggest that both plants have the potential to thrive in the same land units.…”

Research conducted by Rahmawaty et al (2021b;2023a) regarding kemenyan and research conducted by et Rauf et al (2015); Rahmawaty et al (2021a;2023b) regarding gambir has indicated that kemenyan and gambir share similar land characteristics across various parameters. These criteria include factors, such as: temperature (tc), water availability (wa), root media (rc), nutrient retention (nr), and the erosion hazard (eh).…”

“…Altitude can affect media, nutrient retention, water viability, and erosion (Rahmawaty et al 2023). Lowlands have higher light intensity and environmental temperatures than medium and highlands.…”
