Abstract

Pekebunan kelapa sawit di Indonesia telah berkembang secara signifikan dalam 20 tahun terakhir. Perluasan areal perkebunan kelapa sawit telah mengarah ke lahan-lahan marjinal seperti lahan sulfat masam dan gambut. Lahan marjinal untuk pengembangan perkebunan kelapa sawit bukanlah suatu pilihan, tetapi karena keterbatasan lahan semata. Reklamasi lahan sulfat masam dengan mendrain lahan rawa akan membuat kemasaman tanah meningkat drastis dan dapat mengganggu pertumbuhan tanaman. Selain itu drainase juga dapat membuat sejumlah besar hara ikut tercuci. Penelitian bertujuan untuk mengetahui pengaruh kedalaman pirit terhadap beberapa sifat kimia tanah serta produksi kelapa sawit. Penelitian dilaksanakan melalui survei lapangan di perkebunan kelapa sawit PTPN VII, unit usaha Bentayan, Sumatera Selatan. Analisis contoh tanah dilaksanakan di Laboratorium Kimia dan Kesuburan Tanah, Departemen Ilmu Tanah dan Sumberdaya Lahan, Fakultas Pertanian, IPB. Pengamatan dilakukan pada blok-blok dengan kedalaman pirit < 30 cm, 30-60 cm, dan > 60 cm, produksi dikumpulkan pada blok-blok tersebut dan diambil contoh tanahnya. Selain itu juga diambil contoh tanah berpirit yang belum dan telah mengalami drainase. Hasil penelitian menunjukkan bahwa kedalaman pirit < 30 cm memiliki pengaruh yang sangat nyata terhadap meningkatnya kemasaman tanah, Al yang dapat dipertukarkan, berkurangnya N-total, K dan Zn serta penurunan produksi tanaman kelapa sawit. Drainase menyebabkan kecenderungan terjadinya penurunan kadar P, Ca, Mg, dan Cu, serta kejenuhan basa.

Abstract

Stabilitas agregat menentukan kualitas tanah dan polisakarida adalah agen agregasi utama partikel tanah. Penelitian bertujuan mempelajari stabilitas agregat dan polisakarida sebagai agen agregasi partikel tanah masam yang diperlakukan dengan Brachiaria decumbens (BD), mikoriza dan kompos jerami diperkaya kalium di Kebun Percobaan Tegineneng BPTP Lampung. Penelitian ini menggunakan rancangan acak lengkap faktorial 3 faktor. Faktor 1, rumput Brachiaria decumbens, yaitu tanpa B. decumbens (B0) dan dengan baris B. decumbens (B1); faktor 2, mikoriza yaitu tanpa mikoriza (M0) dan dengan inokulasi mikoriza (M1); dan faktor 3, kompos jerami diperkaya kalium yaitu kompos 2 ton ha-1 masing-masing diperkaya KCl masing-masing 0 kg ha-1 (K0), 50 kg ha-1 (K50), 100 kg ha-1 (K100) dan 200 kg ha-1 (K200). Hasil penelitian menunjukkan perlakuan BD dan interaksi BD dan mikoriza mendorong fragmentasi agregat makro menjadi agregat meso dan mikro, namun stabilitas agregat dibawah pengaruh perlakuan tersebut lebih baik dibanding stabilitas agregat tanah kontrol. Inokulasi mikoriza memperbaiki stabilitas agregat makro 1-2 mm. Pengayaan kalium pada kompos jerami secara rata-rata tidak berpengaruh terhadap stabilitas agregat tetapi dalam interaksi dengan B. decumbens, pengayaan kompos jerami dengan 100 dan 200 kg KCl ha-1 berpengaruh cukup baik terhadap stabilitas agregat makro 2-5 mm. Polisakarida total di dalam agregat tanah pada perlakuan interaksi B. decumbens dan mikoriza nyata meningkat, demikian juga polisakarida bukan selulosa cenderung lebih baik. Perlakuan B. decumbens meningkatkan kadar polisakarida total di dalam agregat meso (0.25-1 mm) dan mikro (0.05-0.25 mm), sedangkan mikoriza meningkatkan polisakarida total dan polisakarida bukan selulosa di dalam agregat makro (> 1 mm).

Abstract

Acid soil is commonly grown with cassava, which in general, tolerate low soil  fertility and aluminum (Al) toxicity. However, without any improvement efforts such soil will become worse. Intercropping cassava with Brachiaria decumbens (BD) which adapts to acid soil and tolerates low fertility soils as well as application of arbuscular mycorrhiza (AM) and organic matters are among the important efforts to rehabilitate this soil. The experiment was conducted to  examine the impact of BD, AM, and potassium (K) enriched rice straw compost on exchangeable Al, available K, and stability of soil aggregates. Experiment was arranged in a completely randomized design with three factors and three replications. The first factor was BD as cassava intercropping, the second factor was AM, and the third factor was 2 t ha-1 rice straw compost enriched with 0 kg, 50 kg, 100 kg, and 200 kg KCl ha-1. Brick pots (1 m length x 1 m width x 0.45 m depth) filled with Kanhapludult soil was used for growing cassava in which row of BD was planted at 60 cm from cassava stem. K-enriched rice straw compost and AM (10 g per stem) were applied around cassava stem at 2 and 12 days after planting, respectively. BD was cut every 30 days and the cutting was returned to the soil. Soil exchangeable Al was analyzed at 0, 3, 6 and 9 months after planting (MAP), while Al and K contents as well as aggregate stability were measured at 6 MAP. The results showed that planting BD decreased 33% exchangeable Al, which means that the root exudates of this grass was effective in detoxifying Al3+. Treatment of BD and/or in combination with AM was effective in preserving K added to the soil, increasing total polysaccharides, and improving soil aggregate stability. This indicated that planting BD and applying AM and Kenriched rice straw compost improved acid soil fertility, and therefore can be recommended in cassava cultivation.

Abstract

The Effect of Water Management and Rice Genotypes to Against Toxicity of Iron and Productivity of Rice in Tidal Land Type B in South Sumatera. Tidal land is one of the alternative land to support increased productivity of rice, but rice productivity in this area is still low, and the land utilization is not optimal yet. One factor is high iron content in the soil that can be toxic to plants. The purposes of this study were (1) to determine the effect of water management and rice genotype, as well as their interaction on the percentage of leaf bronzing, growth and yield of rice in tidal lands, (2) to select an alternative combination of water management and rice genotypes that may increase rice yields in tidal land. This study was conducted from February until June 2013 in the tidal area with type B overflow, Mulia Sari village, Banyu Asin regency, South Sumatera. The experimental design used was a split plot design with three replications. The main plot was water management with four levels, while the subplot was rice genotypes consisted of three genotypes. The results showed that water management and its interactions with plant genotypes had significant effect only on the percentage of bronzing, Fe content in shoot, and Fe content in root crops, while the plant genotype significantly affected all observed variables. The use of genotypes tolerant to iron toxicity (Indragiri) combined with (form stagnant and saturated water management) drainage with intervals of two weeks could give yield 6.8 and 6.2 t/ha respectively.Keywords : Water management, genotype paddy, tidal landABSTRAKLahan pasang surut merupakan salah satu lahan alternatif untuk mendukung peningkatan produksi padi, tetapi produksi padi di lahan ini masih rendah, dan pemanfaatan lahannya belum optimal.

Abstract

FTIR spectroscopy combined with canonical variate analysis was used for differentiation of java tea (Orthosiphon stamineus) according to their geographical origin. FTIR spectra of all java tea samples were acquired in the mid infrared region (wavenumber range 4000-400 cm-1). Preprocessing signal of FTIR spectra has been carried out prior to canonical variate analysis by standard normal variate. Combination of FTIR spectra in the region 1800-900 cm-1with canonical variate analysis has the power to differentiate java tea samples in terms of geographical origin. The developed method could be used for identification of geographical origin of java tea based on the samples used in this study.
