“…This volume weight value is influenced by several factors, including texture and structure, soil management, plant species, organic content, and others. The journal states that the density of mineral soils is usually around 2.6 -2.8 g/cm 3 , while the specific gravity of soil organic matter particles ranges from 1.3 -1.5 g/cm 3 [4] . From the calculation results, sample P3 has normal porosity in mineral soils.…”

East Sumba Regency is an dry climate area, which has an impact on water availability, especially for agricultural production. Additionally, this area has a large area of land that can be optimize for productive agricultural areas. Several factors that affect productive land are climate, land management, and water availability. Climate classification can represent the right time for cultivation according to the availability of water. The aims of this research are to determine climate classification in East Sumba Regency. Further, land suitability for rice and planting season were determined. Mohr and Scmidth -Ferguson methods were used in this study to determine climate classification. While calculation of water demand war carried out using the Van de Goor and Ziljsha methods, depend on a constant rate in lt/sc/ha during the land preparation period. Meanwhile, some parameters such as organic matter, N total, climate criteria, water availability, topography, and soil fertility were collected to determine land suitability for rice production. Crop water requirement (CWR) of rice was calculated by using CROPWAT. According to Mohr's method, The East Sumba Regency included in V climate type with 4-5 months of what months and 6-7 months of dry months. While Scmidth -Ferguson method resulted that this area has type E (slightly dry) which has a Q value ranging from 100 -167. Land suitability analysis had several components that need Analysis of land criteria based on physical conditions in the field, including the average temperature (℃) around 24.1 -29.1, rainfall (mm/month) 0 -262, humidity (%) 69 -87, texture class slightly fine to fine, soil CEC (cmol/kg) 12. 58 -15.09, pH H2O 7.06 -7.18, C-Organic (%) 2.53 -2.84, moderate total N, slope < 3, moderate landslide hazard very light. Based on these values, Sumba Regency is categorized as S1 (very suitable) for rice production. These results of this study are expected to increase rice productivity in terms of the technology used, climate and climatology analysis, determination of land suitability, and rice planting period.

“…Volcanic residual soil can cover flat or sloping areas, reaching thicknesses of up to tens of meters. This soil covers an essential part of the world's surface, including the formation of slopes, areas occupied by urban settlements, structures, and infrastructure, and can create environmental problems, such as landslides, erosion, and land degradation [19][20][21][22][23][24][25][26][27][28][29][30].…”

In West Lampung, Sumatra, Indonesia, tropical volcanic residual soils are formed from weathering of volcanic breccias in hydrothermal alteration areas with a thickness of up to 20 m. This soil has the characteristics of clayey silt, low to high plasticity, brownish-red color, has the potential to swelling, easily eroded, and slide when it is saturated, and contains the minerals kaolinite, halloysite, illite, dickite, nacrite, montmorillonite, despujolsite, hematite, and magnetite. The results showed that this soil can cause corrosion of steel and is widely used by the community as a medium for growing plants and vegetables and as a foundation for infrastructure (for example, houses). The volcanic residual soil of the research area had Low Rare Earth Element (LREE) potential and specific uses. The soil with characteristic low plasticity has Liquid Limit (LL) brine value <50% will be suitable for agriculture purposes, building foundations, and earth construction. At the same time, the other category is soil with intermediate to high plasticity characteristics, which has an Liquid Limit (LL) brine value >50%, was more ideal for the primary forest.
