Abstract

Respirasi tanah terdiri atas respirasi autotrof dan heterotrof. Pada lahan gambut, respirasi heterotrof setara dengan laju dekomposisi bahan gambut. Penelitian ini bertujuan mengembangkan model potensial redoks (Eh) tanah sebagai penduga respirasi heterotrof dari perkebunan kelapa sawit pada lahan gambut tropika. Respirasi tanah diukur menggunakan metode sungkup tertutup pada plot close-to-tree (berjarak 2 m dari pohon) dan far-from-tree (4.5 m dari pohon), sedangkan untuk respirasi heterotrof pada plot root-cut (4.5m dari pohon) yang disiapkan dengan pemotongan akar hingga kedalaman 80 cm dan diinkubasi selama 8 bulan. Respirasi tanah pada lokasi penelitian 40.81 ton CO2 ha-1.th-1, 50.53% darinya berasal dari respirasi komponen heterotrof (RKH). Respirasi heterotrof berkorelasi positif dengan Eh tanah pada pH 7 di kedalaman -30 dan -90 cm (Eh7~30 and Eh7~90) dan berkorelasi negatif dengan tinggi muka air tanah. Nilai koefisien korelasi linier sederhana yang signifikan, r= 0.84 dan 0.87; n= 12, dengan RKH masing-masing ditunjukkan oleh Eh7~30 and Eh7~90. Oleh sebab itu, kedua faktor tersebut dapat disarankan sebagai penduga RKH dengan persamaan: RKH (ton CO2 ha-1.th-1) = 18.2 + 0.029 Eh7~30 + 0.037 Eh7~90 (Eh dalam mV).

Abstract

One of the management challenges in pineapple cultivation at plantation scale is the still occurrence of disparity in land productivity across the cultivated area although the cropping practices have been implemented for many years. In the case of a pineapple plantation in Central Lampung Regency, contribution of soil biochemical properties in terms of various soil enzyme activities as a determinant factor of land productivity has never been elaborated. This research was aimed to study the relationships among biochemical and other soil properties with land productivity or pineapple yield at plantation scale. Rhizosphere soil-composite samples were taken purposively from 4 stations at the largest Indonesian pineapple plantation representing blocks with high and low yield and growth at vegetative and generative phase. Relationships amongst the studied parameters were evaluated using PCA and linear multiple regression analysis. The results showed significant contributions of the rhizosphere soil properties on the pineapple yield according to equation: Yield = 64.895 – 6.546 PCA1 +13.057 PCA2 – 7.722 PCA4 (R2= 0.612), where PCA1 consisted of soil available-P, available-K, and CEC; PCA2 was of soil base saturation, total microbe population, enzyme activities of cellulase and invertase, while PCA4 was of soil organic C, silt fraction, and phosphatase activities.

Abstract

From an Indonesian volcanic tuff taken from parent material layer of an Andisols profile, it was separated ‘nanoclay’ fraction of <200 nm particle size. The separated ‘nanoclay’ exhibits pH-dependent charge characteristic due to the presence of allophane in the tuff. Therefore, it can be utilized as a natural anionic adsorbent since its separation process was conditioned to proceed at pH <4.0. This study aims to compare phosphate adsorption characteristics of positively charged ‘nanoclay’ based on Langmuir, Freundlich, Brunauer-Emmett-Teller (BET), and Dubinin-Radushkevich (D‒R) isothermal models. The ‘nanoclay’ was separated using US Patent No. US2010/0187474 A1 procedure that was modified in this study with addition of HCl treatment. The results showed that after 48 h equilibration, application of Langmuir and D‒R model resulted adsorption capacity (qe para-meter) of 460.78 (two-sites) and 439.66 mg.g-1 (heterogeneous sites), respectively, while BET and Freundlich model resulted respectively adsorption at the first adsorptive layer (qmono parameter) of 111.11 mg.g-1 (multilayers) and adsorption constant (1/n parameter) of 0.28. The later indicated that the studied ‘nanoclay’ was a high-quality adsorbent (1/n value 0.1-0.5). Limitations and advantages application of each model were discussed. However, Langmuir showed the best performance in term of linear equations with the highest R2 values obtained.

Abstract

Drainage following conversion of peatlands to oil palm plantations is always associated with carbon (C) loss, one of which is dissolved organic carbon (DOC). Analytical procedure commonly used to determine DOC is the high-temperature combustion (HTC) method, which requires an expensive instrument. An alternative low-cost method has been developed. The objectives of this research were to determine and validate the most suitable UV-Vis spectrophotometer’s wavelength for estimating DOC concentration and evaluating its dynamics from an oil-palm plantation Indonesian-peatland. The DOC concentrations were measured on ground water and canal water samples at wavelengths of 254, 270, and 350 nm and the analytical results were then validated against those reference values resulted from the use of HTC method using Total Organic Carbon Analyzer (TOC Analyzer), based on simple regression analysis. The results showed that the most suitable wavelength for estimating DOC concentration using UV-Vis spectrophotometer was 350 nm. The DOC concentration in groundwater (35.67 ± 8.40 mg L-1) were around two times greater than in canal water (16.26 ± 4.15 mg L-1). The DOC flux from the research area were at the range of 0.66 ˗ 1.15 g C m-2 month-1, with an average of 0.85 g C m-2 month-1.

Abstract

Andisols are specifically characterized by a very high P adsorption capacity owing to their acidic reaction and dominance of variable-charged clay minerals. This crop cultivation problem can be overcome by potassium humate amelioration intended to exchange the adsorbed soil P fractions into the more available (labile) forms. This study aims to evaluate the effects of potassium humate application at 0, 20, 40, and 60 kg ha-1 on the dynamics of P fractions and their relationships with the chemical properties of an Indonesian Andisol. Using the Tiessen and Moir procedure, PH2O, PNaHCO3-Pi-Po, PNaOH-Pi-Po, and PHCl fractions were obtained in topsoil (0–30 cm) and subsoil (30–60 cm) samples 16 weeks after the treatment. The organic soil P (PPo) fractions tended to increase and were attributed positively to total P and negatively to base saturation (BS) at the topsoil, whilst the subsoil PPo fractions tended to increase with the decreasing soil BS. At 60 kg ha-1, the potassium humate application effectively decreased PPo and increased PPi fractions in the subsoil. The results also revealed that humic acid component of potassium humate was an effective organic ligand exchanger for the adsorbed PPo fractions that simultaneously altered soil anion-cation equilibrium in the studied Andisol. As an implication, soil P availability was increasing.

Abstract

Indonesia is rich with volcanic tuff-derived Andisols that contain variable charged minerals. This research was aimed at to extract nanoclays (diameter <200 nm) from volcanic tuffs, and to evaluate their potential as natural adsorbent of phosphate as contaminant in waters. Volcanic tuffs were taken from the 3rd (tv3) and 4th(tv4) layers of an Andisol profile at the foot slope of Salak Mountain Indonesia using dispersion-ultrasonication-centrifugation-dialysis separation procedure. By dispersing the materials in an acid condition (pH 4.0) followed with ultrasonication, it could be separated positively-charged nanoclays (nc3 and nc4) from the negative ones. The separated nanoclays were then purified using centrifugation and membrane dialysis techniques. Potential of the extracted nanoclays as natural phosphate adsorbent was evaluated by characterizing their adsorption maxima (b values) according to the Langmuir isothermal adsorption model. It could be extracted 2.82 mg nc3/g tv3 and 4.29 mg nc4/g tv4. The b values of nc3 at 12, 24, and 48 hours equilibration time (76.48, 92.10, and 117.54 mg P/g nc3) were higher than those of nc4 (50.17, 59.52, and 71.99 mg P/g nc4). The most effective equilibration-time was 48 hours. The extracted nanoclays were considered prospective as natural adsorbent for removal phosphate contaminant in waters
