Abstract

Arabica coffee (Coffea arabica L.) is one of the high economic value plantation commodities, where the level of production is largely determined by land suitability. Scientific information related to specific land suitability in potential areas, such as Solok Regency, is still minimal. This research was conducted in Nagari Koto Gadang Guguk, Gunung Talang District, West Sumatra, with the aim of assessing the level of land suitability for Arabica coffee cultivation. The research was conducted from August to November 2024 through field surveys, laboratory analysis, and Geographic Information System (GIS)-based mapping at a scale of 1:50,000. Analysis included soil physical characteristics (texture, effective depth, drainage), chemical properties (pH, organic carbon, cation exchange capacity, base saturation), as well as topography and climate factors. Results showed that the study land was dominated by dusty loam to dusty clay textures with medium to high C-organic content (2.68-3.12%), slightly acidic pH (5.50-6.18), medium-high CEC values (21.53-32.54 cmol kg-¹), and base saturation of 42.53-68.23%. From the evaluation results, four land units (SL1-SL4) were categorized as S3 class (marginally suitable) with the main constraints of excess rainfall (2,817-3,000 mm/year) and slope (9-40%). Meanwhile, SL5 is categorized as class N (unsuitable) due to drainage problems. The potential to increase land suitability is still open through the application of soil and water conservation, terrace construction, use of adaptive varieties, and improvement of soil and water management. The overall results confirm the importance of land suitability evaluation as a foundation for sustainable Arabica coffee management in the tropical highland region.

Abstract

The physicochemical properties of soil play a crucial role in determining plant growth, development, and productivity. However, these properties are highly dynamic and can change due to management practices as well as natural phenomena such as volcanic eruptions. This study was aimed to analyze the physicochemical properties of soils under several land-use types (forest, coffee, chili, and rice fields) in Nagari Lasi following Marapi eruption on Dec 03, 2023. Undisturbed and disturbed soil samples were collected at depths of 0–30 cm and 30–60 cm. The results showed that, in general, there were no significant differences in either the physical or the chemical properties of soils across land-use types and soil depths. The soil texture in all land uses and depths was classified as sandy–silt loam, with a very low clay content (5–22%). The bulk density (BD) was <0.80 Mg m⁻³, total soil porosity (TSP) was moderate, and the hydraulic conductivity (HC) rate was high (20–31 cm h⁻¹), except in rice fields (5.34 cm h⁻¹). The plasticity index (PI) was low in both soil layers (2.21–5.31% at 0–30 cm and 5.63–7.21% at 30–60 cm). Soil chemical properties were also not significantly different among the land uses, particularly pH (5.12–5.86) and total N (0.13–0.41%) for both depths. However, the C/N ratio in the 0–30 cm layer tended to be lower than that in the 30–60 cm layer.

Abstract

Inadequate solid waste management contributes to soil degradation through increasing acidity, declining organic matter, heavy-metal accumulation, and disruption of soil microbial activity. These impacts are commonly observed around landfill sites, especially in regions with high waste generation. This study aims to assess and compare the Soil Quality Index (SQI) of two landfill areas representing contrasting regional characteristics: Sukawinatan Landfill in Palembang City and Indralaya Landfill in Ogan Ilir Regency. Soil samples were collected at varying distances from the waste mound, and several soil quality parameters—organic matter, total nitrogen, pH, available phosphorus, and moisture content—were analysed. The SQI was calculated using a weighted integration method to provide an overall evaluation of soil health at each site. The results show that the Sukawinatan Landfill exhibits lower SQI values than the Indralaya Landfill, indicating more severe soil degradation due to greater waste volume and higher operational intensity. Increasing distance from the waste pile improved soil quality, although recovery patterns differed between locations. These findings highlight the need for improved waste-management practices and routine soil monitoring to prevent further environmental degradation. The study provides important insights for policy formulation related to landfill management, particularly in urban and peri-urban areas. Key words : Indralaya, Palembang, soil quality, solid waste, Soil Quality Index
