Abstract

Pengerutan dan perubahan geometri penampang merupakan hal yang menyebabkan kegagalan pada proses penekukan pipa. Untuk menghindari kegagalan proses, perlu diketahui mekanisme proses pembentukan kerutan, perubahan geometri penampang dan batasan- batasannya. Pada tulisan ini dibahas mekanisme pembentukan kerutan melalui pendekatan mekanisme buckling pada penekukan pipa. Pengaruh rasio tebal pipa-diameternya dan rasio tebal pipa-radius penekukan terhadap stabilitas geometri pipa dihitung. Kata kunci: penekukan, pipa, buckling, kerutan

Abstract

Solar cell is engineered to convert photon energy of the sun that the earth get it on terrestrial zone. Usually, in laboratory, solar cell will be irriadiated by 1 kW/m2 constant photon source to standardize the product and photovoltaic energy become the output. The productivity of solar cell then be restricted by the photon energy input.In this discussion, the productivity of solar cell will be enhanced by using parabolic concentrator. The restriction of input is broken down by raising the intensity of photon radiation.Key words: solar radiation, parabolic concentrator, solar cell, photovoltaic energy
