Abstract

Soils that are acid sulfuric have low productivity, because the physical and biological conditions of this land are characterized by high acidity. Based on the problem of acid sulphate soil, micro remediation research is carried out to fulfill objectives such as the formation of good and sustainable cultivation land. Acid sulphate soil was taken from at Mesuji Ogan Komering Ilir in January 2023. The method in this study was field observation by taking samples using a belgi drill at several points of the land. The study used a pot with a size of 12 cm x 15 cm which was washed 5 times to remove the acid content in the soil. The pot contains 40% soil, 40% sugarcane husk and 20% rice husk biochar. The object used in this study is the ginger plant. High levels of soil acidity can trigger the dissolution of toxic elements and increase the cause of nutrient deficiencies. Adsorption of complexes in the soil will offer sufficient nutrients for plant development if the soil is rich in soluble bases. Conversely, the soil will tend toward acid if Al and H dominate the adsorption complex. The results of this study can be concluded that micro remediation using sugarcane pulp and biochar has a very real impact. The use of sugarcane bag and biochar in this study helped reduce the initial Al of 9.97 Cmol+/kg to 1.65 Cmol+/kg in the soil and lowered the soil acidity level in the initial soil with a pH of 3.26 to a soil pH of 4.94.

Abstract

Tidal lowland is a marginal land characterized by low pH, deficient  nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the  equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.

Abstract

Tidal marshlands have significant potential for agriculture, despite being affected by fluctuations in sea and river water. This study aims to analyze changes in vegetation density on agricultural land in Sri Mulyo Village, Air Saleh Sub-district, Banyuasin Regency, South Sumatra, using Sentinel-2A satellite imagery and the NDVI (Normalized Difference Vegetation Index) method. Observations were conducted in February, during the wet season, recorded a rainfall of 381 mm, while August, in the dry season, recorded a rainfall of 17 mm, based on data from the BMKG Climatology Station in Palembang for the year 2024, focusing on land cover changes in vegetation density under two different seasonal conditions. The analysis showed a decrease in the area with high vegetation density in August (56.01%) compared to February (63.97%), due to low rainfall and decreased soil moisture in the dry season. In contrast, the medium vegetation category increased in August. These findings suggest that seasonal variations significantly affect vegetation cover and productivity of tidal marshlands. as a consequence, during the dry season, increased drainability and reduced soil moisture contribute to a decline in  vegetation density, with the percentage of areas categorized as “High Greenness” decreasing to 56.01% and those categorized as “Moderate Greenness” increasing to 36.17%. These findings emphasize the crucial role of rainfall in sustaining vegetation in tidal marshlands, particularly under varying seasonal conditions.
