Abstract

Hutan alam rawa gambut yang dialihfungsikan dapat merubah sifat kimia tanah. Penelitian ini bertujuan untuk mengetahui sejauh mana perubahan sifat kimia tanah yang terjadi setelah dilakukannya alih fungsi lahan dari hutan rawa gambut menjadi kebun sawit, HTI Acacia crasicarpa, dan kebun sagu serta mengetahui jenis tanaman mana yang bersifat sustainable (berkelanjutan) pada lahan gambut. Hasil penelitian menunjukkan bahwa pH tanah mengalami peningkatan setelah dilakukannya alih fungsi lahan. Sedangkan kadar air mengalami penurunan. Sifat kimia seperti C-organik, kadar abu, KTK, kejenuhan basa, hara makro (NPK) dan basa-basa dapat ditukar juga mengalami perubahan setelah mengalami perubahan landuse, akan tetapi tidak terdapat pelanggaran berdasarkan pada undang undang yang dibuat oleh pemerintah pada PP. No 25 Tahun 2000 tentang kriteria kerusakan gambut dan Peraturan Pemerintah No. 150 Tahun 2000 tentang pengendalian kerusakan tanah untuk produksi biomasa. Sagu adalah tanaman yang paling sustainable dibanding lainnya karena mengalami perubahan sifat kimia tanah tidak terlalu jauh berbeda dengan landuse lainnya meskipun ditanam dalam jangka waktu yang lama.

Abstract

This study seeks to determine the impact of palm oil wastewater, the number of biopore holes, and their interaction on oil palm plant growth and Dystrudepts soil physical properties. This study was carried out between December 2019 and April 2019. This research was conducted using a 3x3 factorial experiment with a Randomized Block Design; each treatment was replicated three times, and each experimental unit contained three plants for 81 experimental plants. The first variable was the dosage of palm oil effluent, which consisted of 7.5 liter/plant/2 weeks, 10 liters/plant/2 weeks, and 12.5 liters/plant/2 weeks. The second factor had three levels: two biopore holes/plants, four biopore holes/plants, and six biopore holes/plants. Analysis of variance (ANOVA) was applied to the data. If the treatment is markedly different, a second test is conducted using the 5% level of the Honest Significant Difference (BNJ) test. (1) Palm oil mill effluent at a concentration of 7.5 liters/plant increased the total pore space. The effluent from a palm oil mill at a rate of 12.5 liters per plant decreases BD and PD while increasing final plant height, midrib length, leaf length, and chlorophyll content. (2) Adding two biopores per plant increased plant height, midrib length, and leaf width. The presence of four biopores per plant decreased BD and PD and increased leaf length and chlorophyll content. Six openings per plant biopores have an effect on increasing the total pore space, and (3) The interaction between LCPKS doses of 12.5 liters/plant and the number of biopores of 6 holes/plant decreases BD and increases total pore space, plant height, frond length, leaf length, and leaf breadth.

Abstract

This study aims to determine the effect of Endophytes Bacillus sp. and potassium (K), and get the best combination in inducing stem rot disease and growth of oil palm seedlings. This research was conducted at BioCertilizer and Biopesticide Industrial Unit (BICCOM) of Riau University with experimentally using Factorial Randomized Design (RAL) with two factors, 3 replications. The first factor was the concentration of Endophytes Bacillus sp., B1 (3,37x1011 cfu/ml), B2 (2,98x1012 cfu/ml), B3 (2.79x1013 cfu/ml). The second factor was the K dose, consisting of 4 levels: K0 (without K), K1 (0.1 g/polybag), K2 (0.25 g/polybag), K3 (0.5 g/polybag). The data obtained were analyzed statistically with anova and DMRT 5%. The parameters observed were incidence of symptoms, disease intensity, salicylic acid concentration, seed height, leaf number, base diameter, root shoot ratio and seedlings dry weight. The results indicate that Endophytes Bacillus sp. and K fertilizer and single factor K fertilizer did not affect all parameters. Single factor Endophytes Bacillus sp. are able to inhibit the emergence of early symptoms, reduce disease intensity, salicylic acid concentration, seed height, number of leaves, stem diameter and dry weight of seedlings. Combination of Endophytes Bacillus sp. 3.37x1011 cfu/ml and K 0.25 g/polybag tend to increase the number of leaves, stem diameter and dry weight of seedlings.

Abstract

The research aims to examine the effect of the application of waste processing palm oil mill (Empty Fruit Bunches and Palm Oil Mill Effluent) on soil physical properties. The research was conducted at the oil palm plantation at Pelalawan and Laboratory of Soil Science, Faculty of Agriculture, the University of Riau from March to May 2016. The study was conducted experimentally using a Completely Randomized Design (CRD), which consisted of 4 treatments (EFB, POME, EFB+POME and without application as control). Each treatment was repeated 3 times. EFB and POME have been applied to the land since 2001 with intervals giving every 6 months. Soil samples were applied EFB, POME, and EFB+POME taken on Blocks B3, Blocks B7 and Blocks C17. Soil samples were taken at a depth of 0-15 cm and 15-30 cm for disturbed and undisturbed soil. Parameters measured were soil water content, bulk density, particle density, total pore space, permeability, and soil color. Each parameter of the observed data was statistically analyzed using analysis of variance followed by Duncan's New Multiple Range Test (DNMRT) at 5% level, while the soil color was descriptively analyzed. The results showed that the application of a mixture of EFB+POME increased soil moisture and bulk density decrease significantly and tended to increase the total pore space and permeability and tends to be lower particle density than controls, but it was not evident when compared EFB applications and POME alone. Applications waste processing palm oil mill affected the color of the soil where the soil is black on the application mix EFB+POME (hue: 10 YR, value/chroma: 2/1), brown on the application EFB (hue: 10 YR, value/chroma: 4/3 ), dark brown on the application of POME (hue: 10 YR, value/chroma: 3/3) and yellowish-brown in without application (hue: 10 YR, value/chroma: 5/4).
