distribution of magnetic fields in the quiet-sun internetwork areas has been affected by weak polarization (in particular stokes q and u) signals. to improve the signal-to-noise ratio (snr) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. in this study, we aim to investigate a proper temporal-integration time with which...

Abstract One of the food diversification strategies coconut commodity is to process it into Pliek U. U a typical Province Aceh, Indonesia, which in its processing stage requires drying process. So far, often conducted conventionally through direct (sun drying), so that produced susceptible dust and other dirt contamination. This research aimed design dryer using Dafa type solar energy. The ener...

The drying is a basic operation of enormous commercial importance in all industrial applications ranging through the food, agricultural, mining and even manufacturing sectors [1]. Modern societies need better product quality, enhanced safety practices and more environmentally benign operations as well as higher productivity, better energy yield and reduced material wastage, also [2]. As drying ...

Abstrak. Penelitian ini bertujuan untuk menguji performansi alat pengering terowongan Hohenheim generasi ketiga dalam proses pengeringan pliek-u. Parameter yang diukur pada penelitian adalah iradiasi surya, suhu, kelembaban relatif (RH) dan berat bahan. Pengamatan dilakukan interval 1 jam selama dihentikan apabila pliek-u sudah siap dipress. Proses bersifat intermitten yaitu hanya dilaksanakan ...

This study was designed to measure the sound output of four commonly used brands of forced-air dryers used by dog groomers in the United States. Many dog groomers have questions about the effect of this exposure on their hearing, as well as on the hearing of the dogs that are being groomed. Readings taken from each dryer at 1 meter (the likely distance of the dryer from the groomer and the dog)...

Solar tunnel drying and semiwash processing methods are popular among coffee growers in southwestern Ethiopia. However, the effect of these on quality has not been studied detail. The objective this study was to evaluate varieties at Gomma-I Limmu Kossa areas 2016/2017 growing season. Two (fully washed semiwashed) three (solar tunnel, artificial, natural sun) were compared using (741, 7440, 741...

The use of heat exchangers for the process energy conversion from rice husks to thermal as an alternative replacing sun drying. Drying with husk and exchanger does not depend on weather. To determine effectiveness this dryer, a evaluation was carried out drying chamber sample 4 kg shelled corn. test results showed increase in temperature 112.31%. occurred average environmental 30.30oC room 64.3...
