Abstract

The purpose of this study was to determine the quality of sensory and antibacterial activity of liquid soap with the addition of essential oil bangle rhizome. This study used a Complete Randomized Design with five treatments and  three  replications.  The  treatments  were  addition  of  essential  oils  in consecutive S0 (0 ml), S1 (0,62 ml), S2 (1,24 ml), S3 (1,86 ml), and S4 (2,5 ml). The data obtained were analyzed statistically using Analysis of Variance dan Duncan’s New Multiple Range Test at 5%. The research showed that addition of bangle   rhizome   essential   oils   significantly   effected   on   descriptive test and hedonic test. The best treatment of liquid soap in this research was S4 (addition bangle essential oil 2,5 ml) which had result of descriptive test on liquid soap showed that soap had very bangle scents and hedonic test on liquid soap scents was not favored by the panelists. Keywords:  Bangle  (Zingibeer  purpureum  Roxb.),  essential  oil,  liquid  soap, antibacterial

Abstract

This study aims to determine the interaction of  vermicompost and urea and get the best treatment to increase the growth of the gaharu seedlings (Aquillaria malaccensis Lamk.). The research was conducted in experimental station of Agriculture Faculty, University of Riau, from September to November 2016. This research uses Completely Randomized Design, which consists of two factors and three replications. The first factor was the dosage of vermicompost (K) consisting of 4 level: 0 g/ polybag, 100 g / polybag, 200 g/ polybag, and 300 g/ polybag; And the second factor is the dose of urea fertilizer (U) consisting of 4 levels: 0 g/ polybag, 0.5 g/ polybag, 1 g/ polybag, and 2 g/ polybag. Each experimental unit consists of 2 seedlings so that there are 96 gaharu seedlings. Data were analyzed The observation result of each parameter was statistically analyzed by using vocabulary and tested using DNMRT (Duncan's New Multiple Range Test) at 5% level. The parameters observed were plant height, number of leaves, stem diameter, leaf area, shoots and root ratio, and dry weight. The interaction of kascing 300 g/ polybag and urea dosage 2 g/ polybag gave the best effect to the parameters of gaharu seedlings  height accretion, the accretion of leaf number, the accretion of stem diameter, leaf area and dry weight Keywords: Vermicompost, urea fertilizer, gaharu seedlings

Abstract

The aim of this research is to know combination of medium and Trichoazolla compost dosage which can increase the growth of oil palm seedlings in main nursery and determine the best combination of Trichoazolla compost dosage and medium for growth of oil palm seedlings in main nursery. This research uses Completely Randomized Design (RAL) consisting of two factors, the first factor is planting medium consisting of three medium peat level, ultisol medium and mixed peat and ultisol (1: 1). The second factor was Trichoazolla compost consisting of Trichoazolla compost dose 0 g / plant, 75 g / plant, 100 g / plant, 125 g / plant, 150 g / plant. Of the two factors, we got 15 treatment combinations with 3 replications. The parameters measured were the height increase of seedlings, the increase of the number of leaves, the increase of seedling diameter, root canopy ratios, dry weight of seedlings, palm seed oil quality index. The results showed that the growth of oil palm seedlings on peat, ultisol and mixed peat moss with ultisol composted with Trichoazolla 75 g / plant-150 g / plant, was better than without Trichoazolla compost and was able to achieve the standard of seed quality, while Mixed medium composted Trichoazolla compound nutrient seed quality index. Composting of Trichoazolla in peat, ultisol and peat and ultisol combinations may increase seedling height, increase in number of leaves, increase in diameter of tubers in oil palm seedlings.Keyword : Trichoazolla, land and ultisol, oil palm, main nursery

Abstract

The fundamental principles of integrated pest management system is monitoring ecosystem. An important aspect in monitoring ecosystem is observation the abundance of aphids and mealybugs the Citrus nobilis. The purpose of this research is to determine the abundance of aphids and mealybugs the Citrus nobilis Lour. in the of Village Kuok Kuok District Kampar Regency Riau Province. The research using survey method. Observation location was determined by selecting two gardens. Plant samples was determined to the method of systematic sampling with a zig zag pattern. Method was doing of aphids and mealybugs in two types by direct taking on plants and with Moericketraps. Parameters observation were description locations, species identification and total individual ofaphids and mealybugs, abundance of aphids and mealybugs and the persentage attack of aphids and mealybugs. The result showed that abundance of aphids and mealybugs in Citrus nobilis were Toxoptera sp., Aphis gossypii, Aonidiella aurantii, Lepidosaphes beckii, Myzus persicae, aleurocanthus woglumi, Bemisia tabaci and Planococcus citri species. The highest abundance of aphids and mealybugs species in Citrus nobilis was Toxoptera sp.  with 98.90 individual per plant and relative abundance of 37.15%. Keywords: Citrus nobilis Lour., Aphids and Mealybugs, Abundance

Abstract

Increasing need of energy and decreasing of fuel supply, requires human to discover alternative energy resources. Consequently, there should be a research to discover a new renewable energy source such as coconut fiber waste. Coconut fiber are mostly the least used waste from coconut fruit as an alternative energy resources. The method of this research used Completely Random Design (CRD) which consist of 5 treatment and each treatment was repeated 3 times. The treatment was P1 = 96% charcoal flour: 4% adhesive, P2 = 94% charcoal flour: 6% adhesive, P3 = 92% charcoal flour: 8% adhesive, P4 = 90% charcoal flour: 10% adhesive, and P5 = 88% charcoal flour: 12% adhesive. Based on analitycal result of coconut fiber leaves charcoal briquet research, the best quality briquet is the P1 concentration of coconut fiber charcoal is 96% charcoal flour: 4% adhesive, had 7,75% water content, 17,09% ashes content, 72x 10-3 g/s combustion rate, 16,13%evaporated substance rate, 59,02% carbon rate, and 4.704 cal/g heat value.

Abstract

This study aims to inventory, to determined the composition and weed species dominancy of and to determined seedbank germination in various depth of soil in oil palm plantation. This research was conducted at Kebun Sei Galuh PT. Perkebunan Nusantara V, Kampar, Riau. This research was conducted for 3 months, starting from October 2016 until December 2016. This research used observation method. The sampling technique was done by a purposive sampling system with the criteria of land area and the age of the oil palm plant while the dominant weed species was done by vegetation analysis with quadratic methodical. The parameters observed were density (K), Relative Density (KR), Frequency (F), Relative Frequency (FR), and Importance Value Index (INP). The seedbank analysis was done by observing the growing weeds, then identified the species and counted the amount as the number of seedbank in the soil depth of 0 – 10 cm, 10 – 20 cm and 20 – 30 cm. The data that have been obtained are presented in the form of drawings, tabulated based on data groups and analyzed descriptively quantitatively, and presented descriptively qualitatively. Indicator under study in this research is planting year and weed type. The results showed that the diversity of weeds found in the crop produces palm oil consisting of 18 families and 38 species relatively the same and dominated by the family Poaceae and Cyperaceae. Dianella ensifolia, Asystasia intrusa, Eleusine indica is an important and a very dominant weed in all planted areas producing oil palm. Seedbank weeds at a depth of 0 – 10 cm has the largest number of propagules in the appeal at depths of 10 – 20 cm and 20 to 30 cm. Keywords: Inventory of weeds, Seedbank, Oil palm.
