Abstract

Begel or sekang is a longitudinal reinforcing ring to hold the shear stress that occurs in a concrete column or pillar, the putel is placed so that each longitudinal reinforcement is held so as not to bend out. So far, begel are made by sticking a shaft iron into a wood and then begel the iron manually, until it is obtained as needed. Traditional bending tools like this are inefficient because they require more energy to bend them and cannot be carried. Therefore it was designed and made PORTABLE BEGEL MAKING BENDING TOOLS. To test the speed of this tool compared with traditional bending tools. From the results of statistical tests it was concluded that the portable buckle making buckle tool is faster than the traditional buckling tool. This portable buckling device is designed more simply so that it can be carried anywhere and is easily made by construction workers.

Abstract

Indonesia is one of the countries which has high intensity solar radiation. This is very useful in term to exploite solar radiation for drying processes. However, most drying processes are done naturally. This method has many constraints. By improvement of solar collector technology, the drying processes could be done more better. Unfortunately, most solar collectors still have many limitation due to generating high output temperature. Therefore, in this present study, the solar collector is tried to optimizing by enlarging area of frontal surface of solar radiation and increasing rate of air flow out in term to maximize the drying processes. Result shows that by flowing the air constantly (0, 122 m3/s) on 1 m2 surface area will generate output temperatur to approximately 90,2 oC
