Abstract

Andisol is soil located in volcanic mountain areas with the characteristics of black or dark soil and is formed from volcanic ash. The main problem is that Andisol soil has andic properties if the soil is dry, the soil does not easily absorb water anymore and the aggregate stability is low so it is easy for soil particles to be eroded from the hill. andosol. The aim of the research was to examine the influence of cinnamon and coffee plants on the stability of Andisol aggregates, relatively similar to forest soil. The usefulness of research on cinnamon and coffee plants is expected to be able to replace forest vegetation in the physical properties of Andisol soil. The research was carried out in Lembah Masurai District, Merangin Regency. at an altitude of 1300 m above sea level with the Andisol type. The research was carried out over 4 months in 2024. Soil analysis was carried out at the Soil Physics and Chemistry Laboratory, Faculty of Agriculture, Jambi University. Soil sampling to determine soil aggregate density, organic matter content, bulk volume and soil permeability was carried out by survey using the Proportive Random Sampling method in areas planted with cinnamon, coffee, cinnamon mixed with coffee plants and forest soil on a slope of 8% - 15 %. The parameters observed were organic matter content, permeability, soil volume weight, total pore space, aggregate percentage, soil aggregate stability. Each treatment was repeated 15 times. To differentiate the physical properties of Andisol, cinnamon, coffee, cinnamon mixed with coffee and forest soil were planted. carried out with the Unpaired Middle Value Test at the 5% level (Steel and Torrie, 1995). From the results of the Unpaired Middle Value Test, it was found that replacing forest with cinnamon plants, the organic matter content, aggregate percentage, and aggregate stability were the same as forest soil but different from coffee plantings and mixed cinnamon and coffee plantations.

Abstract

This research aims to analyze the effect of rainfall on the peat groundwater level (GWL) in the Mendahara River-Lagan River Peat Hydrological Sub Unit (sub KHG) during the El Nino phenomenon. The analysis was carried out using a simple linear regression method on 3 dominant land covers, namely private oil palm plantations, community oil palm plantations and secondary swamp forests, where 2023 is an El Nino year. The results of the research show that in the year private oil palm plantation land cover had the strongest influence on the amount of rainfall distribution compared to community oil palm plantation land cover and secondary swamp forest with R2 values of 76.14%, 58.03% and 51,42%. The value of the coefficient of determination (R2) means that the dynamics of TMAT fluctuations can be explained by the amount of rainfall distribution, while the rest is influenced by other variables not studied.

Abstract

Karbon organik terlarut (DOC) dalam tanah memainkan peran penting dalam distribusi nutrisi dan konsentrasinya dapat dipengaruhi oleh keberadaan partikel mineral tanah. Kandungan karbon tanah awal dapat mengurangi kapasitas tanah untuk menyerap DOC karena adanya tolakan muatan negatif. Penelitian ini mengkaji pengaruh kandungan karbon dan logam tanah awal terhadapa dsorpsi DOC yang  ditambahkan pada tanah hutan tropis melalui percobaan batch. Kandungan logam berat tanah (Al dan Fe), total karbon organik dan kandungan DOC tanah ditentukan. Untuk menentukan apakah dan bagaimana variasi kandungan karbon tanah mempengaruhi adsorpsi DOC, maka dua tanah dengan kandungan logam dan karbon yang berbeda (tanah permukaan dan bawah permukaan) dari dua sistem transformasi (hutan tropis sekunder dataran rendah dan perkebunan sawit masyarakat digunakan. Karbon organik terlarut diekstraksi dari permukaan tanah yang kaya organik dengan air dan dipekatkan ketingkat yang diperlukan dan digunakan dalam percobaan batch. Karbon organik terlarut berkorelasi negatif dengan kandungan logam tanah terutama pada sub permukaan tanah. Dengan kandungan organik karbon tinggi korelasinya tidak signifikan. Ini mungkin menjelaskan adanya tolakan DOC yang membawa perubahan negatif oleh partikel tanah kaya organik.http://dx.doi.org/10.23960/aec.v6.i1.2021.p12-21

Abstract

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.
