Abstract

Krisis energi saat ini menjadi isu utama dunia beberapa dekade terakhir, pemakaian energi hampir di segala aspek dan semua aktivitas manusia tergantung pada energi, untuk saat ini konsumsi energi dunia masih di dominasi oleh energi fosil (minyak bumi, gas dan batu bara), Mengingat terbatasnya persediaan sumber energi tersebut, maka alternatif energi yang bisa dimanfaatkan adalah energi matahari. Teknologi pemanfaatan energi surya dapat dibedakan menjadi dua yaitu konversi energi surya menjadi listrik melalui sel surya dan pemanfaatan panas matahari menggunakan kolektor surya untuk pengeringan. Kolektor surya yang dipakai dalam penelitian ini adalah kolektor surya dengan plat absorber v-corrugated tipe dimple dengan susunan staggered.
Pada penelitian ini dibahas pengaruh plat Absorber V-Corrugated dengan penambahan dimple dengan susunan Staggered terhadap performasi kolektor surya. Diameter dimple pada plat absorber berukuran 5 mm, 7 mm, 9 mm. Penelitian ini dilakukan secara eksperimen dengan menggunakan cahaya lampu halogen dengan variasi intensitas radiasi 431 W/m2, 575 W/m2, dan 719 W/m2, dan memvariasikan laju massa udara 0.001 kg/s, 0.002 kg/s, 0.004 kg/s dan 0.006 kg/s.
Berdasarkan eksperimen yang dilakukan, hasil yang diperoleh adalah besarnya energi berguna yang diserap oleh fluida kerja kolektor surya berbanding lurus dengan peningkatan laju massa dan intensitas radiasi, Hasil eksperimen untuk plat absorber v-corrugated dengan diameter dimple 9 mm, Qusefull paling tinggi dicapai pada laju massa 0.006 kg/s dengan intensitas radiasi 718 watt/m2 yakni 65.91 Watt dan effisiensi paling tinggi sebesar 65.77 % dicapai pada laju massa aliran massa 0.006 kg/s dengan intensitas radiasi 718 W/m2.

Today's energy crisis became the main issue of the world in recent decades, energy consumption in almost all aspects and all human activity depends on energy, for now the world's energy consumption is still in dominance by fossil energy (petroleum, gas and stone Because of the limited supply of energy sources, the energy alternative that can be utilized is solar energy. Solar energy utilization technology can be distinguished into two namely the conversion of solar energy into electricity through solar cells and the utilization of solar heat using solar collectors for drying. The solar collector used in this study is a solar collector with a V-corrugated absorber plate type dimple with a staggered arrangement.
In this study discussed the influence of plate Absorber V-Corrugated plates with the addition of dimple with Staggered arrangement of solar collector performation. Diameter Dimple on the absorber plate measuring 5 mm, 7 mm, 9 mm. This research was conducted experimentally using halogen lamps with a variation of radiation intensity 431 W/m2, 575 W/m2, and 719 W/m2, and varying the rate of air mass of 0.001 kg/s, 0.002 kg/s, 0.004 kg/s and 0.006 kg/s.
Based on the experiments done, the results obtained are the magnitude of useful energy that is absorbed by the working fluid of solar collectors directly proportional to the increase of mass rate and radiation intensity, results of the experiment for the V-corrugated absorber plate with a diameter of 9 mm dimple, Qusefull is highest achieved at a mass rate 0.006 kg/s with 718 watt/m2 radiation intensity of 65.91 Watt and the highest efficiency of 65.77 % achieved at mass flow mass rate of 0.006 kg/s with radiation intensity 718 W/m2.
