Abstract

Peat nutrient dynamics research was intended to study the characteristics and distribution of macro nutrients in peat water and peat in secondary forests, shrubs and oil palm plantations. This research was conducted with purposive sampling method. Observations on oil palm plantations were carried out at three ages of oil palm (5, 12, and 16 years). Secondary forest and shrub peatlands were used as a comparison. Sampling of peat water and peat was carried out during the rainy and dry season, at four distances from the collection drain (25, 50, 75, and 150 m). The results showed that nutrient levels in peat water during the dry season were greater than the wet season. The status of peat water and peat nutrients in secondary forests and shrubs is relatively the same as that of oil palm plantations that were fertilized. Seasonal, land use and distance from the collection channel differences did not have a major influence on the distribution and characteristics of macro nutrients on peat. The macro nutrients content of peat water and peat, however, showed an increase with the distance from the collection channel.

Abstract

Perubahan penggunaan lahan hutan menjadi perkebunan kelapa sawit diduga mengubah distribusi fraksi fosfor (P) tanah. Penelitian ini bertujuan untuk mengevaluasi fraksi P pada lapisan permukaan tanah di lahan hutan dan perkebunan kelapa sawit di Jambi, serta korelasinya dengan sifat kimia tanah. Sampel tanah diambil dari lapisan atas tanah hutan dan perkebunan kelapa sawit. Beberapa sifat kimia tanah dan fraksi-fraksi P dianalisis. Fraksionasi P dilakukan dengan menggunakan metode Tiessen dan Moir. Hasil penelitian menunjukkan bahwa fraksi P agak labil yaitu NaOH-Porganik (-Po ) dan -Pinorganik (Pi) merupakan fraksi yang ditemukan dominan di hutan dan perkebunan kelapa sawit. Persentase P labil (resin-Pi, NaHCO3-Pi,-Po) dan P organik agak labil (NaOH-Po) dari total fraksi P ditemukan lebih tinggi di lahan hutan dibandingkan dengan perkebunan kelapa sawit. Fraksi NaOH-Pi di perkebunan kelapa sawit lebih tinggi nilainya dibandingkan dengan di hutan. Hal ini menunjukkan bahwa secara alami perubahan penggunaan lahan hutan menjadi kelapa sawit mengubah distribusi fraksi P sebagai akibat dari perubahan kandungan karbon (C) organik tanah. Analisis korelasi menunjukkan bahwa hampir semua fraksi P berkorelasi positif dengan C organik, mengidentifikasikan bahwa mineralisasi C organik mempengaruhi distribusi fraksi P yang artinya C organik tanah mengontrol distribusi fraksi P pada lapisan permukaan tanah di lahan hutan dan perkebunan kelapa sawit.

Abstract

Heavy metals have been reported to accumulate in sediment of Citarum River. The measurement of total heavy metals may not be able to provide information about the exact dimension of pollution, thus the determination of different fractions assumed great importance. This study was performed to determine chemical fractions of heavy metals (Cu, Ni, Cr, Pb and Cd) in sediment collected at 8 locations from Citarum River. The sequential extraction procedure was used to extract heavy metals in water-soluble, acid-soluble, MnO occluded, organically bound, FeO occluded and residual fraction in sediment. Bioavailability and potential ecological risk level of heavy metals were evaluated based on bioavailability factor (BF) and risk assessment code (RAC) method. The results showed that Cu, Ni, Cr were mostly in residual form, indicate those from geological sources. Cu had low bioavailability and no risk in all sediment samples of Citarum River. Ni and Cr each was found to have risk at 2 locations. Pb and Cd were found dominantly in non-residual fraction, suggest those from anthropogenic sources. BF and RAC analysis of Pb and Cd suggest that there is a potential risk to the aquatic environment.

Abstract

Illegal gold mining activities still frequently occur in the Kuantan River, which is one of the main rivers in the district of Kuantan Singingi, Riau. This activity causes environmental contamination of mercury (Hg). The objective of this research was to determine the contamination of Hg in river water, well water, sediment and fish (baung and kapiek) in the Kuantan River, Riau. Samples were taken at up, middle and downstreams of the Kuantan River. Mercury was analized by following APHA and Indonesian National Standard (SNI) methods. The results were compared with the quality standard of pollution. The results showed that average of Hg concentration in river water, well water, sediment and fish were 0,0325 mg/l, 0,0202 – 0,0231 mg/l, 0,2083 mg/kg, 0,1141 - 0,1224 mg/kg. Statistical analysis indicated that the concentration of Hg in river water, well water (middle and downstream) and sediment were above the quality standard, while in the samples of baung and kapiek were below the quality standard. Hg concentrations significantly increased from up to downstream locations in river water and sediment, Hg concentrations significantly increased in 2 community wells in middle and downstream locations, significant Hg concentration was found in kapiek caught in midstream locations, while there was no significantly at the Hg concentration of baung in the research location.

Abstract

CO2 flux from peat soil planted with oil palm is temporally and spatially dynamic, which is related to various environmental factors. This flux can be partitioned into fluxes from oil palm root respiration, litter decomposition, and peat material decomposition. The aim of this study was to determine the temporal and spatial dynamics of CO2 fluxes, the contribution of oil palm roots respiration, the contribution of litter decomposition, and the relation between flux and environmental factors in oil palm plantations on peatland. Measurements of CO2 flux using an infrared gas analyzer (IRGA) were carried out in harvesting path and inter raw of oil palm plantation, and nearby bushland. Flux measurements were repeated every three to four days for almost five months. Results showed the dynamics of the CO2 fluxes temporally and spatially. Temporally, CO2 flux in oil palm plantation and bushland ranged from 2.9 – 11.1 and 0.5 – 6.4 g C-CO2 m2/day, respectively. Spatially, the flux in oil palm plantation and bushland ranged from 4.8 – 8.8 and 2.7 – 3.4 g C-CO2 m2/day, respectively. The contribution of oil palm roots respiration and litter decomposition were 48.4 and 5.8%, respectively. These results confirm that plant roots respiration plays an important role in the release of carbon from the soil surface.

Abstract

Nitrogen oksida (N2O) adalah gas rumah kaca yang berumur panjang dan memiliki potensi pemanasan 300 kali lebih tinggi dari CO2. Pelestarian hutan rawa gambut dapat mempertahankan sifat fisik dan kimia tanah pada kondisi alaminya, sehingga emisi N2O terjadi secara alami. Dalam upaya mengkuantifikasi emisi N2O dari ekosistem lahan gambut, ketersediaan data sangat dibutuhkan. Tujuan penelitian ini adalah untuk mengukur emisi N2O dari hutan konservasi, dan untuk memahami faktor-faktor utama yang mengendalikannya. Penelitian ini dilakukan dari bulan Januari sampai Desember 2020 di Semenanjung Kampar, Kabupaten Pelalawan, Provinsi Riau. Hasil penelitian menunjukkan emisi N2O pada hutan konservasi lahan gambut sebesar 0.23 ± 0.19 kg-N/ha/tahun. Perubahan subtansial pada tinggi muka air tanah, suhu tanah, kelembapan tanah, ruang pori terisi air, NH4-N and NO3-N secara signifikan mempengaruhi pertukaran gas N2O antara lahan gambut dan atmosfer.
