Abstract

AbstrakBakteri rizosfer adalah bakteri yang terdapat pada daerah perakaran tanaman yang diketahui memiliki keanekaragaman tinggi. Bakteri rizosfer memiliki berbagai peran seperti menyediakan nutrisi bagi tanaman, melindungi tanaman dari infeksi bakteri patogen, menghasilkan hormon pertumbuhan seperti indol acetic acid, pelarut fosfat, pengikat nitrogen, dan lain-lain. Dengan berbagai kemampuan dan peran tersebut, maka perlu eksplorasi bakteri rizosfer tanaman sawit khususnya di daerah perkebunan agar diketahui kelompok bakteri rizosfer, sehingga dapat dimanfaatkan secara optimal. Penelitian ini bertujuan untuk mengetahui kelompok dan keragaman bakteri rizosfer pada tanaman sawit yang berumur 8, 11, dan 14 tahun. Penelitian dilakukan dengan pendekatan konvensional dengan karakterisasi morfologi dan uji biokimia. Dari umur-umur tersebut, didapatkan 18 isolat yang terdiri dari 11 genus, yaitu Bacillus, Azospirillum, Actinobacillus, Xanthobacter, Enterococcus, Paenibacillus, Klebsiella, Pseudomonas, Arthrobacter, Micrococcus, dan Streptococcus. Bakteri rizosfer tanaman sawit memiliki keragaman genus yang sama pada umur 8, 11, dan 14 tahun. Genus bakteri yang didapatkan dapat dimanfaatkan sebagai PGPR (Plant Promoting Rhizobacteria).Abstract Rhizosphere bacteria are bacteria found in root areas. Rhizosphere bacteria have various roles such as providing nutrients for plants, protecting plants from infection pathogenic bacteria, producing growth hormones such as indol acetic acid, phosphate solvents, nitrogen binders, and others. By having these various abilities and roles, it is necessary to explore the bacteria of oil palm plants, especially in the plantation areas so that the group of rhizosphere bacteria can be identified and then utilized optimally. This study aims to determine the group and diversity of rhizosphere bacteria in oil palm plants that are 8, 11, and 14 years old. The research was conducted conventionally by observing morphological and biochemical characterization. At those ages, 18 isolates were consisting of 11 genera, namely Bacillus, Azospirillum, Actinobacillus, Xanthobacter, Enterococcus, Paenibacillus, Klebsiella, Pseudomonas, Arthrobacter, Micrococcus, and Streptococcus through conventional methods. Rhizosphere bacteria in oil palm plants have the same genus diversity at the ages of 8, 11, and 14 years. The bacterial genus obtained can be used as PGPR (Plant Promoting Rhizobacteria).

Abstract

Soil fertility parameters, including macronutrients, micronutrients, and metal content, are very important for optimizing agricultural and plantation land management. Ultisol is a type of soil that is commonly used as a planting medium for oil palm plantations, rubber, and various types of vegetables. Continuous land use causes variations in nutrient and metal content. This change is also caused by the fertilization process and the characteristics of the plants grown in the area. In this study, an analysis of soil fertility parameters (macronutrients, micronutrients, and metal content) was analyzed using X-Ray Fluorescence (XRF) on Ultisol soil taken from Muara Jambi Regency, Indonesia. This analysis was conducted across land-use areas (Palm, Rubber, Vegetables, and Forest). Subsequently, the obtained measurements were used to model correlations with soil pH values to predict soil fertility parameters. The quantitative results showed that the metal content values were reasonably consistent across all locations regarding metal types and their percentage concentrations. However, locations 1 (T1) and 2 (T2) have higher aluminum (Al) content than locations 3 and 4 and lower magnesium (Mg) content. The modeling, when correlated with pH values, indicated that metal elements correlated 0.938, macronutrients 0.934, and micronutrients 0.767. From these correlations, it can be qualitatively inferred that there is a strong relationship between pH and the presence of metal content, macronutrients, and micronutrients. In the future, this can serve as a model for estimating the presence of soil fertility parameters.

Abstract

Informasi akan kandungan tanah penting diketahui sebagai dasar pengolahan pertanian. Pada Kabupaten batang Hari kecamatan pemayung Provinsi Jambi terdapat dua jenis tanah yang sering dimanfaatkan sebagai lahan pertanian yaitu tanah Ultisol dan Inseptisol. Dalam pemanfaatan sebagai lahan pertanian terhadap kedua jenis tanah tersebut umumnya pelaku pertanian melakukan penanaman langsung sehingga sering kali mendapatkan hasil yang kurang optimal akibat ketidaksesuaian jenis tanaman dan pupuk yang digunakan, untuk itu pada penelitian ini dilakukan karakterisasi terhadap tanah tersebut. Sampel tanah diambil dari 6 titik lokasi dengan ukuran 1km x 2km, selanjutnya dilakukan preparasi untuk pengukuran unsur logam dengan menggunakkan X-Ray Fluorescence (XRF), uji kandungan C-Organik dan pH. Hasil pengujian XRF menunjukkan bahwa daerah aluvial (Inseptisol) memiliki kandungan Mg dan C-organik lebih tinggi daripada tanah Ultisol dimana rata-rata kandungan Mg >18% dan C-Organik >14% serta memiliki kandungan Al dan Si lebih rendah, dimana Al <20% dan Si <25%. Untuk nilai C- Organik tanah inseptisol (aluvial) memiliki C-organik lebih tinggi (>14%) dan pH lebih rendah (<5) dibandingkan dengan tanah ultisol. Dari hasil pengujian kandungan tanah diharapkan pelaku pertanian pada daerah tersebut dapat mengetahui gambaran kandungan tanah dengan cara melakukan pencocokan pendekatan terhadap sampel tanah yang telah dilakukan pengujian pada penelitian ini.
