Keanekaragaman Mikrob Tanah Gambut di Bawah Hutan dan di Bawah Perkebunan Sawit di Provinsi Jambi

Abstract: Drainase lahan gambut diperkirakan akan mempengaruhi populasi dan keanekaragaman hayati di tanah gambut. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh drainase dan tutupan lahan gambut di Tanjung Jabung Timur, Provinsi Jambi terhadap populasi dan keanekaragaman mikroba tanah gambut. Sampel tanah gambut diambil dari tiga lokasi yang berbeda yaitu: (A) perkebunan sawit dengan kedalaman saluran drainase 50-70 cm, (B) perkebunan sawit dengan kedalaman saluran drainase 20-50 cm, dan (C) hutan gambut… Show more

“…The total population of cellulolytic bacteria was lower in oil palm fields with a depth of 0-15 cm (6.80 x 109 cfu/g to 6.90 109 cfu/g) than in oil palm fields with a depth of 15-30 cm (8.30 x 109 cfu/g to 9.90 109 cfu/g) (Figure 4.2). This contrasts with the findings of Pratiwi et al (2018), who discovered that the overall population of bacteria in peatlands under oil palm stands is 0-20 cm greater (2.10 x 108 cfu/g) than 20-40 cm (4.50 x 105 cfu/g). In general, as soil depth increases, so does the microbial population.…”

“…subsidence, which occurs due to peat compaction, decomposition and erosion processes, (3) has a low bearing capacity to pressure, (4) has a low nutrient content, both macro and micro nutrients so that it is relatively infertile, and (5) has a limited number of microorganisms [20]. The results of research and mapping of peat in Bangka Island, North Kalimantan Province, Papua Province and Jambi Province show that the fertility level of peat soil is low [21,22,23,24]. Table 1 shows the chemical characteristics of peat soil planted with oil palm in Jambi Province.…”

“…Perbedaan jumlah populasi ini dapat diakibatkan karena teknik budidaya yang digunakan berbeda serta kesesuaian ekosistem awal bakteri dengan medianya. Penelitian yang dilakukan Pratiwi et al (2018) menunjukkan bahwa pengolahan tanah dan pemupukan mempengaruhi pertumbuhan mikroba. Petani di lokasi 1 memberikan pupuk kotoran hewan ayam.…”
