Phrases in Arabic and Indonesian Language

This research is about differences and similarities of phrase construction in Arabic and Indonesian. The approach in this paper was a descriptive qualitative analysis approach. The findings of this study revealed that some construction of the phrase structure is the same. Subordinative noun phrases are equivalent to idhafah in Arabic, Indonesian adjective phrases are similar to na'at in Arabic, Indonesian coordinative phrases are similar with athaf in Arabic and Indonesian prepositional phrases are similar to syibhul-jumlah in Arabic. However, there are differences between both languages which can be found in Idhafah in Arabic, some vocabulary cannot be called phrases in Arabic, and vice versa. Differences can also be found in the use of athaf letters in the equivalent of coordinative phrases. The differences are also found in the numeral phrases and murakkab adadi. Even taukid and tarkib majazi do not have the equivalent in Indonesian. The differences are not only due to structural aspects, but also by differences in cultural concepts and expressions. This study implies that errors can be predicted in the construction of Indonesian student phrases and the production of translations of Arabic phrases that are different from the construction of Indonesian phrases. The differences were found not only in the structure but also in differences in cultural concepts. This study shows that mistakes can be predicted from the formation of phrases and the translation of Arabic sentences that are different from the structure of Indonesian language

Optimization of Co-Flow Jet Parameters for Ahmed Body Application

This study evaluates the drag reduction strategy of suction and blowing on idealize automotive vehicle,Ahmed Body. Optimization approach is adapted in order to analyse the effect of slot location, momentumcoefficient and slot angle on the vehicle which experiencing drag. Despite all the efforts that have been done toreduce the Ahmed body drag using various active flow control system, most of the drag reduction were only lessthan 15%. A 25° Ahmed body with build in co-flow jet is modelled using a CAD software. The flow around theAhmed body is simulated at Reynolds number based on length Re = 4.29 × 10 6 . The governing equation were solveusing an open source software package, which has been validated against experimental data. Pressure Implicit withSplitting of Operator (PISO) algorithm is applied to solve the equation. The outcome of the simulation are variesdepending on the variables. Some show a decrease in drag while there are also that actually increase the drag of thesystem. This are caused by the suction and blowing slots that effect the surrounding air flow whether it is reducingor increasing the wake size downstream of the body. The result shows the momentum coefficient and location ofboth suction and blowing jet played an important role of manipulating the flow around the body and reducing thedrag. The velocity contours indicated that the key to drag reduction is by using 40 m/s jet velocity, placement ofsuction and blowing away from each other. &nbsp
