ABSTRACT Over time, peatland is now changing its function into plantation land such as oil palm plantations on peatland. However, in the management of peatland, it is necessary to pay attention to the nature of peat and soil ir levels, including the regulation of groundwater level. Based on the physical properties of peat soil can be used as an indicator in determining the productivity of oil palm plants on peatlands. Where the important karesteritic in peatland is the water content, soil volume weight, the content of organic matter and the ability to withstand the load of subsidence and non-return dry. Oil palm plants (Elaeis guineensis Jacq.) come from Nigeria, West Africa. Yes, oil palm plants thrive outside their native areas, such as Malaysia, Indonesia, Thailand, and Papua New Guinea. Oil palm plants have an important meaning for the development of national plantations. In addition to being able to create job opportunities and lead to the welfare of the community, palm oil is also a source of foreign exchange for the country and Indonesia is one of the main producers of palm oil. This research was conducted in Karya Bhakti Village, Rantau Rasau District, East Tanjung Jabung Regency. Soil analysis was carried out at the Soil Laboratory of the Faculty of Agriculture, Jambi University. The research was conducted by survey using Proportional Random Sampling. The observed parameters are the height of the water level in the soil, the height of the canal water level, the content of organic matter. Volume Weight, Total Pore Space., peat depth, peat maturity. Each age of palm oil plants, 10 samples were taken at three ages of palm oil plantations 0-5 years, 6- 10 years and eleven years and above. Data interpretation on the age of oil palm oil plants 0 - 5 years, 6 - 10 years and > 11 years was carried out using the Unpaired Middle Value Test on the parameters of soil water level, canal water level height, organic matter content, soil volume weight, peat soil water content. To see the relationship between the height of the peat soil water level with several physical properties of the soil, it was carried out using the Simple Regression Test. The results of the study by using the Unpaired Middle Value Test on the parameters of the groundwater level and the height of the canal water level in palm oil aged 0 - 5 years are clearly different from oil palm plants aged 6 - 10 years and palm oil aged > 11 years. Based on the Linear Regression Test, there is a relationship between the water level of the peat soil and the average water level of the canal in the mustard coconut plant as much as R = 73,33% Keywords: Groundwater Level and Physical Properties of Peat, Palm Oil Plants.

Peatland characteristics are an important consideration in land management for agricultural development. As peat depth increases, nutrient availability and microbial activity tend to decline, while soil acidity (pH) increases. Thicker peat layers therefore have a significant influence on soil fertility. Oil palm (Elaeis guineensis Jacq.), originating from Nigeria in West Africa, is widely cultivated in Malaysia, Indonesia, Thailand, and Papua New Guinea. Oil palm plays a strategic role in national plantation development by creating employment opportunities, improving community welfare, and contributing substantially to national foreign exchange earnings, with Indonesia being one of the world’s major palm oil producers. This study was conducted at an oil palm plantation in Sungai Tawar Village, Geragai Subdistrict, East Tanjung Jabung Regency. The research was carried out over four months during 2024–2025. Soil analyses were performed at the Soil Laboratory, Faculty of Agriculture, Universitas Jambi. The study used a survey method with purposive random sampling. Observed parameters included groundwater table depth, soil organic carbon (C-organic), peat depth, macronutrient content (N, P, and K), and peat maturity. Observations were conducted on oil palm stands aged 11 and 16 years, with ten soil sampling replications for each plant age. Data interpretation to identify differences in soil depth and NPK content between oil palm ages was conducted using an independent t-test for C-organic content, N, P, and K levels, groundwater table depth, peat thickness, and peat maturity. The relationship between C-organic content and NPK was analyzed using simple linear regression. Results showed strong correlations between peat layer depth, groundwater level, and nitrogen availability, as well as between soil C-organic content and total nitrogen, available phosphorus, and total potassium across different oil palm ages.

Introduction: Jambi Province is a region prone to moderate to heavy rainfall events that are often triggered by mesoscale convective systems such as squall lines. This study aims to analyze atmospheric conditions, squall line characteristics, and their impact on surface rainfall. Three squall line events on May 7, 2024, June 21, 2024, and May 17, 2025, were selected as case studies. Methods: The research methods include analysis of 3000 ft wind data, 850–500 mb layer humidity, 925 mb air pressure, Himawari-08/09 satellite imagery, weather radar data, and AWS rainfall. Radar data were processed using Rainbow software, while satellite data were analyzed using Sataid. Results and Discussion: The results show that the three squall line events are supported by high air humidity (70–90%), wind deflection, and a low pressure center along Sumatra. Weather radar is able to clearly display the formation and decay of squall lines, with a linear convective structure that is not detected by satellite imagery. Measured rainfall varied from light to heavy rain in areas crossed by the squall line. Conclusion: Weather radar is the most effective instrument in identifying the squall line in Jambi, while satellite imagery only supports monitoring convective clouds. These results are important as a basis for improving the accuracy of early warnings for extreme weather.

Introduction: Cadmium (Cd) levels in well water near the Talang Gulo Landfill (TPA) reached 0.064 mg/L, approximately 19 times higher than the clean water quality standards set by the Minister of Health Regulation No. 02 of 2023. Cd concentrations decreased with increasing distance from the landfill, indicating the mobilization of Cd from the landfill soil into the surrounding environment. Given the toxic and highly mobile nature of Cd, mitigation efforts are needed to suppress the movement of this heavy metal. Objective: This study aims to evaluate the effectiveness of palm oil shell biochar in immobilizing cadmium (Cd) in landfill soil through changes in solubility under water extraction and simulated acidic conditions. Methods: This study used a laboratory experimental method with the addition of palm oil shell biochar to the Talang Gulo landfill soil at doses of 0%, 5%, and 10% and an incubation time of up to 60 days. Results and Discussion: The addition of biochar can increase soil pH and significantly reduce Cd mobility, with immobilization efficiency increasing with increasing biochar dose and incubation period. Conclusion: Palm oil shell biochar has the potential to be used as an environmentally friendly ameliorant solution for the remediation of cadmium-contaminated soil

The objective of this study is to examine the relationship between soil properties and aggregate stability in oil palm plantations, influenced by varying distances from the Betara River. Soil analysis was conducted at the Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Jambi University. Soil samples were collected using the Proportional Random Sampling method across plantation areas located at distances of 50 m, 500 m, 1000 m, and 1500 m from the river. The parameters observed included soil organic carbon content, soil moisture content, bulk density, total pore space, percentage of soil aggregates, and aggregate stability. Each treatment was replicated 15 times. To determine the physical properties of the soil and their relationship with river proximity, an independent sample t-test at a 5% significance level was used, followed by multiple linear regression analysis (Steel and Torrie, 1995). The results showed that the distances of 50 m and 500 m had similar values for organic matter content, bulk density, total pore space, moisture content, permeability, aggregate percentage, and aggregate stability. However, these values differed significantly from those observed at distances of 1000 m and 1500 m. Furthermore, multiple linear regression analysis revealed that organic carbon content and soil moisture were the dominant factors influencing aggregate stability, with a correlation coefficient (R) of 0.77. This study provides empirical evidence on how river proximity affects soil physical properties and aggregate stability in oil palm plantations. It highlights the importance of soil organic carbon and moisture content as key determinants of aggregate stability, offering valuable insights for land management strategies in riparian agricultural areas.
