Abstract

Aktivitas penambangan di lahan produktif pertanian yang dilakukan masyarakat dapat menimbulkan dampak terhadap lingkungan, diantaranya limbah yang dihasilkan oleh aktivitas penambangan menyebabkan tanah di areal sekitar penambangan mengandung logam berat dan peningkatan degradsasi lahan. Untuk itu, perlu dilakukannya upaya remediasi lahan bekas tambang untuk memulihkan kontaminasi logam berat serta memperbaiki sifat tanah bekas tambang agar produktif kembali. Tulisan ini bertujuan untuk memberikan informasi mengenai potensi biochar dalam upaya meremediasi lahan bekas tambang.  Metode yang digunakan dalam penulisan ini adalah metode studi pustaka dan metode analisa data yang gunakan pada literature review yaitu simplified approach. Hasil studi pustaka dari beberapa jurnal dan artikel mengungkapkan bahwa aplikasi biochar telah banyak dimanfaatkan dan memberi pengaruh yang nyata dalam menurunkan mobilitas dan ketersediaan logam berat pada tanah dan tanaman dengan berbagai mekanisme. Dan yang tak kalah penting, sebagian besar peneliti saat ini telah menunjukkan bahwa biochar merupakan inovasi terbarukan dan berkelanjutan yang dapat dimanfaatkan dalam memperbaiki sifat fisik, kimia, dan biologi tanah bekas tambang hingga pada akhirnya dapat meningkatkan pertumbuhan dan prduktivitas tanaman. Dapat disimpulkan bahwa temuan peneliti-peneliti tersebut membuktikan bahwa inovasi amelioran biochar sangat menjanjikan dan bermanfaat untuk masa depan dalam meremediasi lahan bekas tambang guna mengurangi luas lahan terdegradasi dan mewujudkan keberlanjutan ketahanan pangan di Indonesia.

Abstract

Penggunaan lahan yang berbeda dapat memberikan dampak signifikan terhadap sifat biologi tanah. Di Kebun Percobaan Fakultas Pertanian Universitas Andalas, terdapat beragam jenis penggunaan lahan seperti lahan pertanian, lahan perkebunan, dan lahan hutan. Penelitian ini bertujuan untuk mengetahui tingkat kesuburan biologi tanah di lokasi penelitian. Metode yang digunakan dalam penelitian ini adalah metode survei sederhana. Tanah diambil pada kelerengan yang sama (0-8%) pada beberapa penggunaan lahan yaitu lahan yaitu lahan padang rumput, lahan hutan, dan lahan perkebunan sawit. Sampel diambil pada kedalaman 0-20 cm pada daerah rhizosfir. Hasil penelitian menunjukkan Respirasi tertinggi terdapat di hutan sebesar 2.10 mg CO2/g tanah/hari lalu padang rumput dan lahan sawit masing-masing 0.95 mg CO2/g tanah/hari. C-Biomassa tertinggi di padang rumput yaitu 0.072% lalu lahan sawit 0.018% kemudian hutan 0.011%. Populasi bakteri tertinggi terdapat pada lahan padang rumput yaitu 6.21 CFU, kemudian hutan 5.92 CFU, dan sawit 5.58 CFU. Kadar enzim pospatase baik yang aktif di pH masam maupun basa, nilai tertinggi terdapat pada lahan hutan yaitu 10.38 µmol/g (asam) dan 5.68 µmol/g (basa) kemudian lahan padang rumput sebesar 5.87 µmol/g (asam) dan 2.30 µmol/g (basa), dan lahan sawit 3.25 µmol/g (asam) dan 0.90 µmol/g (basa). Berdasarkan analisis, lahan hutan dan lahan pdang rumput masih merupakan lahan dengan sifat biokimia yang masih stabil dan memiliki kesuburan biologi yang baik.

Abstract

Tanah marginal memiliki potensi besar untuk dikembangkan meskipun menghadapi kendala seperti bahan organik yang rendah dan keasaman tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian abu gunung Marapi dan biochar kulit kopi terhadap karakteristik kimia tanah Oxisol. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan menginkubasikan Oxisol dengan amelioran menggunakan 3 ulangan selama 1 bulan. Perlakuan-perlakuan yang diberikan yaitu kontrol (Oxisol tanpa amelioran = K), Oxisol + abu gunung Marapi setara 5 ton/ha (A), dan Oxisol + biochar kulit kopi setara 5 ton/ha (B). Analisis kimia tanah untuk penelitian ini meliputi pengukuran pH tanah dengan perbedaan perbandingan tanah dengan pelarut (1:5 dan 1:10) dan lama pengocokan (30 menit dan 60 menit); P-tersedia metode Olsen dan Mehlik; KTK (ammonium asetat pH 7); % C-organik (Walkey and Black); % N-total (Khjedal); dan % C/N Hasil menunjukkan perubahan signifikan pada karakteristik kimia tanah, terutama peningkatan pH, KTK, dan P-tersedia.

Abstract

Young Coconut Waste Biochar (YCWB) serves as an ameliorative agent that enhances soil quality and facilitates glyphosate removal, particularly in Inceptisols. This study aimed to evaluate the capacity of Inceptisols enhanced with YCWB to eliminate glyphosate, a commonly used herbicide. Inceptisols amended with 40 t ha⁻¹ YCWB demonstrated an increased surface charge, improving soil properties such as acidity (pH), electrical conductivity (EC), cation exchange capacity (CEC), and soil organic matter (SOM). The adsorption capacity was determined to be 0.87 mg g⁻¹ (or 870.27 mg kg⁻¹) at pH 5.07, under a glyphosate concentration of 100 mg L⁻¹. Glyphosate removal was facilitated by changes in functional groups, as indicated by Fourier-transform infrared spectroscopy (FT-IR), which showed reduced transmittance of O-H, C=C, C-O, C-H, and mineral groups. These modifications indicate an enhancement in the sorption capacity of Inceptisols treated with 40 t ha⁻¹ YCWB. The glyphosate adsorption isotherms followed the sequence: Langmuir > Freundlich model, with performance ranking as soil + 40 t ha⁻¹ YCWB > unamended soil (Inceptisols). The respective R² values were R² = 0.9889 > R² = 0.9739 for the Langmuir model and R² = 0.9953 > R² = 0.9099 for the Freundlich model, confirming a strong interaction relationship (R² > 0.9). This indicates that glyphosate removal occurs through simultaneous or alternating physical and chemical processes. Modifying the surface charge of Inceptisols using biochar-based amelioration technology derived from biomass waste, such as young coconut waste, is critical for improving glyphosate removal efficiency.

Abstract

As an ameliorant, rice husk biochar (RHB) can improve soil quality and long-term carbon absorption and interaction with glyphosate during adsorption. This study investigated the ability of Inceptisol ameliorated with RHB to absorb glyphosate. Inceptisol ameliorated with 40-t ha-1 RHB increased the soil surface charge (ΔpH) by improving soil pH H2O, electrical conductivity, cation exchange capacity, and soil organic matter. Linear and nonlinear models showed that fitting Langmuir and Freundlich isotherms is suitable for this study. The isotherm adsorption of glyphosate sequentially occurs in the Freundlich and Langmuir models (Inceptisol + 40-t ha-1 RHB > Inceptisol), where the Freundlich model (R2 = 0.938) is dominated by glyphosate adsorption on Inceptisol + 40-t ha-1 RHB with n of 0.46 and KF of 1.747 mg kg-1, whereas the Langmuir model (R2 = 0.8608) with Qm of 30.01 mg kg-1 and KL of 0.08 L mg-1 at a concentration level of 100 ppm and pH of the glyphosate solution 5.20 units. The glyphosate adsorption was also supported by changes in functional groups, where Fourier transform infrared spectroscopy shows a decrease in transmittance in the O-H; C=C; C-O; C-H, and mineral groups, indicating an increase in the adsorption capacity in Inceptisol ameliorated with 40-t ha-1 RHB. This study indicated that the physicochemical properties of Inceptisol are important in controlling the glyphosate adsorption ability of RHB in soils.

Abstract

The optimal utilization of oil palm empty fruit bunch (OPEFB) waste holds significant potential for biomass bioconversion via slow pyrolysis, presenting a promising alternative for producing high-quality biochar as a soil ameliorant. This study investigates the effects of slow pyrolysis temperatures (≤ 300 °C) on the physicochemical properties of biochar derived from OPEFB and evaluates its efficacy as a soil ameliorant. This study utilized a completely randomized design (CRD) with three replications across two experiments. The first experiment assessed the effect of slow pyrolysis temperature on the quality of biochar derived from OPEFB, with treatments set at four temperatures (150, 200, 250, and 300 °C) levels. The second experiment evaluated the impact of the selected biochar on the surface charge of oil palm plantation soil, applying biochar at five different doses (0, 20, 40, 60, and 80 tons ha-¹). The potential temperature of 200 °C in slow pyrolysis had a significant effect on the quality of biochar from OPEFB with a yield ratio of 27.84% char; proximate (91.95% volatile matter and 0.81% fixed carbon), cation exchange capacity (CEC) [167.73 cmol(+) kg-1], and macro and micronutrients (e.g., C, N, P, K, Ca, Si, Fe, Cu, Zn, and Mn). The potential of O-H, N-H, C-H, and C=O functional groups of biochar from OPEFB for nutrient availability and absorption efficiency proven by the effect of 40 tons ha-1 biochar from OPEFB which significantly increased 80% of soil surface charge [pH by 0.80; organic matter (OM) composition by 19.8%, CEC by 11 cmol(+) kg-1] and nutrients [0.93% C; 0.04% N; 17.57 ppm P2O5; 0.65 cmol(+) kg-1 K] on Inceptisols.
