Abstract

Triiodobenzoic acid (TIBA) is a plant growth regulator that may accelerate the change of vegetative growth into reproductive growth by modifiying the ratio of hormones that already exist. The purpose of this study was to determine the effect of TIBA and phosphorous fertilizer on peanut (Arachis hypogea L.). This study was conducted using a split plot design with three replications. The main plot was three levels of TIBA concentration; ie, 0 ppm, 50 ppm and 75 ppm. Subplot was four levels of phousphorous fertilizer; ie, 0 kg, 11,5 kg, 23 kg and 34,5 kg of  P2O5. Parameters measured were plant height, flowering age, number of primary branches, dry weight of plants at 28 days after planting, dry weight of plant at 35days after planting, plant growth rate, harvest index, pods dry weight per plot and seed weight per plot.The results showed that TIBA significantly affected pods dry weight and seed weight per plot, but not significantly affect plant height, flowering age, number of main branches, dry weight of plants at 28 days after planting, dry weight of plants at 35 days after planting, plant growth rate, and harvest index. Application of phosphorous fertilizer only affected harvest index, pod dry weight and seed weight per plot. TIBA and phosphorous interaction affected pod dry weight and seed weight per plot. Application of P2O5  fertilizer 34,5 kg per ha and TIBA with concentration of 75 ppm resulted higher pod dry weight and seed dry weight per area than other treatments. Keywords:Triiodobenzoic Acid, peanuts, phosphorous, plant height, seed weight.

Abstract

The purpose of this research was to the best obtain the ratio of red bean flour and sago starch selected in the making of crackers. This research used Complete Randomized Design (CRD) with 6 treatments and 3 replications which were followed by Duncan’s New Multiple Range Test (DNMRT) at level 5%. The treatments in this research included K0S0 (ratio of red bean flour and sago starch 100 : 0), K1S1 (ratio of red bean flour and sago starch 90 : 10), K2S2 (ratio of red bean flour and sago starch 80 : 20), K3S3 (ratio of red bean flour and sago starch 70 : 30), K4S4 (ratio of red bean flour and sago starch 60 : 40), and K5S5 (ratio of red bean flour and sago starch 50 : 50). The result of analysis showed that the ratio of red bean flour and sago starch significantly affect on water content, ash content, protein content, and sensory test. The best treatment crackers was K5S5 with water content (2,33%), ash content (2,18%), protein content (8,57%), and sensory test with colour of yellowish brown, flavorful red beans and sago starch, a little taste of red beans and sago starch, crunchy texture, and overall assesment of crackers was  preferred by the panelist. Keywords: crackers, red bean flour and sago strach

Abstract

The experiment aims to know the effect of interaction giving coffee pulp compost and NPK and get a good dose for the growth of oil palm seedlings in nurseries main. This research was carried out in the farm of Technical Implementation Unit Departement of Agrotechnology, University of Riau, from February to Juny 2016. The research was conducted experimentally using a completely randomized design factorial with two factors such as factor of coffee pulp compost (K) consists of 3 extents that are coffee pulp compost 0 g/plant (0 ton/ha), coffee pulp compost 50 g/plant  (10 tons/ha) and coffee pulp compost 75 g/plant (15 tons/ha). The second factor is NPK consists of 4 extents that are NPK 0 g/plant, NPK  6,25 g/plant, NPK 12,5 g/plant and NPK 18,75 g/plant. Two factors obtained 12 combined treatment with 3 replications, so that there are 36 experimental units. Each experimental unit consisted of two plants, so there are 72 plants. Parameters measured were plant height increase, in the number of leaves, the increase in diameter tubers, seedling root volume and dry weight of seedlings.The result showed no interaction effect giving coffee pulp compost and NPK at oil palm seed Tenera varieties (DXP)Marihat age of 3-7 months to all parameters observed. Giving coffee pulp compost dose of 75 g/ plant (15 tons / ha) were able to increase the height increment of seeds as big as 1,09 % and dry weight of oil palm seedsTeneravarieties (DXP), Marihat age of 3-7 months. Key words : coffee pulp compost, NPK, oil palm seeds

Abstract

Biodiesel is an alternative fuel made from vegetable oil or animal fat that can be used as a substitute for diesel fuel. The purpose of the research was to see the effect of methanol addition on biodiesel from used waste cooking oil. The research used a completely randomized design with four treatments which were M1 (methanol 65 ml), M2 (methanol 75 ml), M3 (methanol 85 ml) and M4 (methanol 95 ml) with four replications. The data were analyzed using Analysis of Variance (ANOVA) and continued with duncan’s new multiple range test (DNMRT) at 5% level. The best treatment was M4 with acid number of 0.42 mg KOH/g, total glycerol content of 0.08%, kinematic viscosity of 26.35 cSt, water content of 0,01%, flash point of 227°C, saponification number of 123.46  mg KOH/g and levels of methyl ester 99.4%.Keywords: Biodiesel, waste coocking oil, methanol, ash catalyst

Abstract

The research aimed to determine the effect of shade and NPK fertilizer and get the dose of NPK fertilizer at various levels of better shade to the growth of cocoa seedlings. The research was conducted in the experimental station of agriculture faculty of Riau University from June to September 2017. The research was conducted in the form of experiments arranged in a split plot design used a complete random design (RAL) consisting of 2 factors and 3 replications.The main plot is a shade consisting of no shade, 50% shade and 75% shade, sub plot is the dose of NPK fertilizer 0, 2, 4, 6 g/polybag.Data have been statistically analyzed and examined further with using the smallest real difference test (BNT) at 5% level.The outcomes indicated that there is interaction between shade and NPK fertilizer on cocoa leaf area, but no interaction on seedling height, leaf number, stem circumference, root volume, shoot root ratio and dry weight. Giving a of 75% shade have better effect on the parameters of seedling height, leaf number, stem circumference, leaf area, root volume, shoot root ratio and dry weight. The dose of NPK 4 g/polybag fertilizer gave better effect to parameters of seedling height, leaf number, stem circumference, leaf area, shoot root ratio and dry weight. Giving 75% shade with a dose of NPK 4 g fertilizer showed the best treatment on all parameters for the growth of cocoa seedlings. Keywords:Cocoa seedlings, shade, NPK fertilizer, growth
