Abstract: Bamboo is an alternatif material to replace the steel reinforcement in concrete, it have almost equal in tensile strength. Concrete plates with knitted bamboo reinforcement can be used to withstand the lateral load. By using bamboo knitting reinforcement, concrete plates have different bending stresses than concrete using steel reinforcement. Knitted bamboo is also used to overcome the bond slip that occurs to the action of concrete composite with bamboo. In this study, The lateral loads received concrete plates with bamboo knitting reinforcement. It supported by two facing edge is pinned, one edge is fixed, and one edge is free. In this case, the the position of plates is put horizontally and recieved 4 joint load as the uniform load. to compare experiments with theoretical it is necessary to use finite element analysis by using abaqus program to find the deflection value, strain, and crack pattern that happened in bamboo reinforcement. By eksperiment, Maximum load that can be retained by concrete plate with bamboo reinforcement with 3 knits that is equal to 625,17 Kg, deflect at 15,24 mm and strained at 4,11 x 10-5. By Finite element analisys in maximum loading is deflect at 12,8 mm and strained at 4,68 x 10-5.

Study of using bio-phosphorus fertilizers on maize plant under alkaline soil conditions
Abstract:This study aims to use bio-phosphorus fertilizers (compost with co-inoculation PDB) on the growth of maize plants under alkaline soil condition.
A field experiment was carried out at the Experiment Station, Faculty of Agriculture, Sirte University During the year (May- September). Tow factorsexperiment was conducted in a split plot design with three replications. Phosphorus fertilizer types were applied to the main plots. The area of the sub-plot was 10.50 m2 (3.5 m length *3 m width), with 5 ridges 60 cm apart and 25 cm between hills. The experiment included 35 treatments which were the combination of four types of phosphorus fertilizer types and seven rates of phosphorus application. Five phosphorus fertilizer types (Rouk phosphate (RP) plus 1% compost, RP plus 4% compost, RP plus 7% compost, RP plus 10% compost and ). These mixtures were inoculated with phosphate dissolving bacteria. Seven phosphorus fertilizer rate (0, 3, 6, 9, 12, 15 and 18 Kg P/fed). Were applied in a single dose before sowing.The increases in yield of maize using RP+10%compost organic matter and inoculation with DPB in increasing the solubility of P from RP besides supplying the plants with some other macro and micronutrients.
