Abstract

Giam Siak Kecil Biosphere-Bukit Batu (GSK-BB) is Riau  peatlands area which is largest composed by lowland peat swamp forest ecosystem. Seeing peatland ecosystem getting extreme, there will be small possibility that soil microbes are able to breed optimally, but microbes in tropical land has not been explored. However, the high content of organic matter, allowing soil microbial activity in the organic matter recycle that essential to life such as nitrogen cycle. Non-symbiotic nitrogen fixing bacteria is a free-living bacteria and plays a role in the supply of N in the soil. The results of the isolated and characterization of single bacterial isolates obtained 31 non-symbiotic N fixing of GSK-BB peat Biosphere which allegedly largest to genus Azotobacter, Azospirillium and Clostridium pasteurianum as well as the results of clear zone isolates on the medium modification, from the single isolates contained 14 isolate that potentially in a non-symbiotic N with the largest ratio of clear zone obtained HTA1 10-4 NS-2, HTA1 10-4 NS-1, HTA 4 10-4 NA-1 dan HTA5 10-4 NS-2.

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 study was carried out at the Laboratory of Plant Biotechnology Faculty of Agriculture, University of islam Riau Pekanbaru. The timing of the study during the three months from October to December 2013. The design used in this study is the factorial experiment in completely randomized design (CRD), which consists of two factors and three replications. The first factor is the provision of Myoinositol: A0 (0 mg/l), A1 (25 m/l), A2 (50 mg/l), and A3 (75 mg/l).While the second factoris the provision of active charcoal: B0 (0 g/l), B1 (1 g/l), B2 (2 g/l), and B3 (3 g/l). From the results of this study concluded that the provision of various concentration of Myoinositol treatment singely provide significant effect on all parameters of the observations with the best treatment A2 (50 mg/l Myoinositol administration) that age emerged shoots (20,25days), sum up shoot (2,11 fruit) shoot height (2,32 cm), sum up roots (3,00 fruit) and weight wet roots (26,39 mg). Treatment provision of various consentrations of active charcoal.Singely provide significant effect on all parameters of the observations with the best treatment B2 (1 g/l active charcoal administration) that age emerged shoots (23,92 days), sum up shoot (2,06 fruit)shoot height (2,01 cm), sum up roots (2,67 fruit)and weight wet roots (25,59 mg). Interactions are granting various concentrations of Myoinositol and active charcoal provide significant effect of the parameters of the observation age emerged shoots with the best treatment in the combination treatment A2B0 (16,33 days), and weight wet roots with the best treatment A2B0 (47,47 mg) Myoinositol, Arang Aktif, Anggrek.

Abstract

Mustard is one of the horticultural crops that have commercial value and nutritious. The research was done in September to December 2013 in Faculty of Agriculture and Animal Sciences Experimental Garden, State Islamic University of Sultan Syarif Kasim Riau. This research was carried out to study the doses of market waste bokashi, planting period and the interaction both of them to planting mustard plants in verticulture system. Randomized Complete Block Design (RCBD) with five replications was used. Treatments involved two factors, i.e. market waste bokashi doses (0, 150, 300, 450 and 600 g per gutters) and planting period (first and second). Observations were done on six morpho-agronomic characteristics, i.e. plant height, number of leaves, leaf length, leaf width, canopy wet weight and canopy dry weight. The results showed that the giving of bokashi 300 g/gutters in the first planting period gives the best results on plant height (28,88 cm), number of leaves (8,28 strands), leaf length (16,30 cm), leaf width (12,93 cm) and canopy wet weight (37,98 g). Bokashi 600 g per gutters on the second planting period gave similar results by using bokashi 300 g per gutters in the first planting period.

Abstract

This research aimed to determine the effect of the interaction giving cellulolytic microorganisms and inorganic fertilizers or single factor to the growth of immature oil palm plantations. This research has been conducted in land PT.Tunggal Perkasa Plantation Air Molek, District Pasir Penyu,  Indragiri Hulu-Riau. The research was carried out for 4 months, starting from July to October 2012. This study uses a Randomized Block Design factorial with 3 replications, the first factor is the treatment dose selulotik microorganisms composed of 4 levels (0 mL /plant, 10 mL /plant, 20 mL /plant, 30 mL /plant) and the second factor inorganic fertilizer treatment consists of 2 levels (half the recommended dose and 3/4 the recommended dose). The results showed that the interaction of cellulolytic microorganisms and low doses of inorganic fertilizers have  significant effect on the increase in the number of midrib and circumference of stem. Single factor cellulolytic microorganisms giving significant effect on plant height increment, while the single factor inorganic fertilizers giving significant effect on the increase the circumference of stem and number of leaflets.

Abstract

Soybean is legume plant that has ability to symbiosis with Rhizobium. This process produces nitrogen thus decrease the need of urea fertilizer. The purpose of current research was to investigate the effect of Rhizobium and urea dosage on growth and yield of soybean. The research was conducted in experimental field of Agriculture and Animal Science Faculty of State Islamic University of Syarif Kasim Riau, started from May until July, 2012. Peat soil media and soybean cv. Wilis were used in this study. Randomized Completed Block Design with two factorials and three replications was employed for experimental design, in which the first factor was the Rhizobium (with/without Rhizobium application) whereas the second factor was dosage of urea fertilizer (0, 75, 150 and 225 kg/ha, respectively). The following parameters were observed e.g. plant height, number, weight and diameter of root nodules, flowering time, age of harvest time, number of pods/plant, number of seeds/pod, weight of 25 seeds, weight of dry seed/plant, weight dry plant, weight dry root and colour of leaf. The result showed that Rhizobium application increased the number of pods/plant. Urea fertilizer with dosage of 225 kg/ha increased number of seeds/plant, weight of 25 seeds, weight of dry plant, and weight dry seed. Interaction between Rhizobium and urea fertilizer were significantly different to weight dry root.
