Abstract

Peat land conversion into oil palm plantations leads was increased emissions of carbon dioxide (CO2). Plants on peat land and environmental conditions believed to be factors in the emission of carbon dioxide (CO2). The porpuse of this research was determined the emissions of carbon dioxide (CO2) in oil palm plantations are intercropped with cropping crop on peat land and the influence of environmental factors on the emission of carbon dioxide (CO2). This research was conducted in September 2015 until April 2016 in Rimbo Panjang village, Subdiscrict Tambang, District of Kampar, Province of Riau. Cropping crop used were corn and soybeans. The method used in this study was a Random Block Design with four treatments and four replications. The treatments were palm - berau, palm oil - corn, palm oil - soybean, palm oil – intercropping (soybean – maize). Parameters measured were carbon dioxide (CO2), soil temperature, air temperature, the temperature of the lid, the depth of the water table and soil pH. The results showed that carbon dioxide emissions (CO2) in oil palm plantations are intercropped with cropping crop (corn and soybeans) were not significantly different. The influence of air temperature, soil temperature, the temperature of the lid, and the depth of the ground water level were inversely and  insignificant to the emission of carbon dioxide (CO2). As for getting nearly neutral pH, the emission of carbon dioxide (CO2) is increasing, but insignificant.

Abstract

This study was conducted from July to December 2011 in the Tanjung Pauh village, Sub district of Singingi Hilir, District Kuantan Singingi. The purpose of this research was to observe the impact of the conversion of forest land into oil palm plantation at various planting year on soil chemical properties, including; C-organic, N total, pH, and cat ion exchange capacity. The method used is the method Observe with correlation and regression to determine the effect of conversion of forest land into oil palm plantations. Sampling of land consists of forest, plant oil palm plantation ages various planting year 2, 8, and 16 years. The parameters analyzed were pH, C-organic, cat ion exchange capacity, nitrogen total. Results showed that conversion of forest land into oil palm plantations shows the changes in soil chemical properties including, pH, C-organic, cat ion exchange capacity, total N and organic matter. Over the conversion of forest soil led to increased soil pH, which is forest land (4.49), oil palm age of 2 years (4.52), oil palm age of 8 years (4.76) and age 16 years (5.02). The results of this study indicate oil palm plantations to oil palm trees aged 16 years, still not able to match the conversion of forests in maintaining c-organic. On forest land have C-organic content of 1.87%, and at the age of 2 years of planting 1.05%, the lowest C-organic contained in the oil palm plantation age of 8 years (1.05%), and increased at the age of 16 years (1:42%). Cat ion exchange capacity in forest land 12.72%, changed to 12.76% at the age of 2 years of planting, growing 13.15% at the age of 8 years and 9.61% at the age of 16 years of planting. Nitrogen total content of the forest land is changed to 0.0285% 0.0427 at the age of 2 years of planting, cropping 0.0425 at the age of 8 years and 0.0283 at the age of 16 years of planting.

Abstract

Rhizobium is a group of soil bacteria that is able to fixing nitrogens from the atmosphere throught symbiosis mechanism with legumes. It has an important role as a provider of nutrients the plants. Regarding of the fact, this research was aimed to isolate the Rhizobium from root nodules of legumes in peatland areas of State Islamic University of Sultan Syarif Kasim Riau. The Rhizobium isolation was conducted in Laboratory of Pathology Entomology and Microbiology of Faculty of Agriculture and Animal Science. The root nodules of legumes were selected and sterilized using 10 % disinfectant solution for 2 minutes before isolated. The Rhizobium colonies were isolated on Nutrient Agar (NA) media. The results showed there were nine isolates of Rhizobium to be isolated. Macroscopic of the colonies showed there were eight isolates of translucen (white-milk) and one isolate was yellowish-white, with spherical on shape, flat edges, convex surface, and sticky textures of colonies. Microscopic of cells were gram-negative bacill with varies of size i.e. 0.42 ± 0.19 µm to 1.075 ± 0.425 µm of length and 0.25 ± 0.03 µm to 0.6 ± 0.15 µm in width. The Rhizobium isolates of Clitoria laurifolia, Acacia sp., and Albizia sp. were three fastest in growth.

Abstract

Aspek kesuburan tanah ditandai oleh baiknya sifat biologi tanah. Salah satu unsur yang penting dari sifat biologi tanah adalah populasi bakteri yang terdapat di dalamnya. Penelitian ini telah dilaksanakan pada bulan Februari sampai dengan Mei 2013 di PT. Tambang Hijau dan Laboratorium Patologi, Entomologi dan Mikrobiologi Universitas Islam Negeri Sultan Syarif Kasim Riau. Penelitian ini bertujuan untuk mengetahui jumlah populasi bakteri yang berada di perkebunan kelapa sawit lahan gambut pada tingkat kedalaman tanah 0 cm (permukaan tanah), 25 cm, 50 cm, 75 cm dan 100 cm, selain itu penelitian ini juga bertujuan menganalisis morfologi bakteri tanah secara makroskopis maupun mikroskopis. Metode yang digunakan pada penelitian ini adalah observasi. Metode pengambilan sampel yang digunakan adalah metode komposit, yaitu menggabungkan 9 anak sampel tanah yang diambil dari 9 titik sampel pada petak tanah yang sama secara diagonal. Hasil penelitian menunjukkan jumlah populasi bakteri tertinggi pada permukaan tanah perkebunan kelapa sawit umur 6 tahun yaitu 1,06x106 CFU, sedangkan populasi bakteri pada permukaan tanah perkebunan kelapa sawit umur 3 tahun yaitu 1,16 x 105 CFU. Hasil pemurnian biakan didapatkan 12 isolat murni yang seluruhnya merupakan bakteri gram negatif, 7 isolat berbentuk coccus dan 5 berbentuk bacil. Perlu dilakukan penelitian lanjutan tentang identifikasi bakteri hingga tingkat spesies.

Abstract

The addition of inorganic fertilizers to overcome the limitations of organic fertilizers in the form of compost pellets affects the microbial life within them. Meanwhile, the biological activity of fungi as biocontrol agents, biofertilizers, decomposers, and plant growth promoters is highly essential. This study aimed to determine the optimal NPK fertilizer dosage for compost pellets. The research was conducted from October to December 2024 at the PEMTA Laboratory, UIN Suska Riau. The research employed a qualitative descriptive method with six treatment levels. The results showed that the treatment without NPK addition produced 7 fungal isolates with a population of 5.0 × 106 cfu/g; addition of 1% NPK yielded 11 isolates with a population of 3.5 × 106 cfu/g; 2% NPK resulted in 10 isolates with 1.0 × 105 cfu/g; 3% NPK had 7 isolates with 6.0 × 105 cfu/g; 4% NPK showed 4 isolates with 5.0 × 105 cfu/g; and 5% NPK had 7 isolates with 1.2 × 105 cfu/g. Referring to the original source of the isolates, which were derived from compost shaped into pellets, the biological activities of the fungal isolates were predominantly decomposers, followed by phosphate-solubilizing fungi. The number of isolates acting as biocontrol agents and producers of plant growth regulators (PGRs) was relatively low.
