Abstract

The research aims to determine the effect of application some concentration of paclobutrazol and to obtain the best concentration on the growth and yield of tomato with one main branch pruned. The research was conducted experimentally by using Completely Randomized Design with treatment of application some concentration of paclobutrazol (K) consist of four levels that is: K0 : without application of paclobutrazol (control), K1 : 300 ppm, K2 : 600 ppm and K3 : 900 ppm. Data were examined using analysis of variance and mean separations with Duncan’s New Multiple Range Test at the 5% level.The results showed that the application of paclobutrazol on tomato plants by pruning the main branches can inhibit plant height and accelerate age appear first interest and does not make a difference by being deprived of paclobutrazol on the parameters of stem diameter, number of flowers per plant, the age of the first harvest, the amount of fruit per plant, weight of fruits per plant and fruit diameter. Keywords: paclobutrazol concentrate, growth and yield, tomato plant.

Abstract

Peat water often used as concrete mixing water in areas that are difficult to get clean water. The characteristic of peat water are acidic and has low pH value, so it is not recommended to use as concrete mixing water because it can reduce the quality of concrete. Material of mineral like Palm Oil Fuel Ash (POFA) used in concrete mixture can imvrove the density and strenght. Beside the addition of mineral materials, improvement of water quality concrete mixer can also improve the quality of concrete. The purpose of this reserach to quantify the compressive strength and porosity of the concrete where the concrete mixing water used is water that has been processed peat. The peat water treathment is acidid neutralized by the alkaline additives. The pH value used as parameter to improve the quality of water by adding additives such as quicklime. The type of cement used in concrete mix OPC and OPC POFA 10%. Peat water in this research from Rimbo Panjang, Kampar and POFA comes from PT. Tarera Bangun Riau, PKS Perhentian Raja, Kampar regency. The result showed that the peat water’s quality has been improved with addition of quicklime will produce the quality of concrete is better than the using peat water without repair.Keywords : Phsycal properties, OPC, POFA (palm oil fuel ash), peat water, additive, quicklime, peat field condition.
