Abstract

A spectral beam splitting concentrated photovoltaic/thermal (SBS CPVT) system is a new technology in PV areas . In order to split the sunlight, the grating lens is used in this study. The tool of this study is G-Solver software which simulates the diffraction efficiency of visible light and infrared light of the blazed and binary grating lens. The aim of this paper is to analyze the potential of the diffraction efficiency of grating lens when applied in SBS CPVT. The result show that binary grating, the highest diffraction efficiency for the visible light is also almost unchanged for the aspect ratio from 1.4 to 2, but the peak wavelength shift from around 360 nm to 510 nm, while, for IR light, the diffraction efficiency decrease from aspect ratio 1.4 to 2. On the other hand, blazed grating, The highest diffraction efficiency for the visible light is almost unchanged for the aspect ratio from 1.4 to 2, but the peak wavelengths shift from around 350 nm to 500 nm. While IR light, the diffraction efficiency decrease with the aspect ratio 1.4 to 2

Abstract

Purpose: This study aimed to increase partners' knowledge and skills regarding the use of various equipment for processing sugarcane into solid brown sugar so as to improve the economy of the farmers. Method: 5 steps were carried out in this activity; determining the location, determining a suitable place for the construction of a sugar factory, determining suitable business units, training on appropriate technology and brown sugar factory assembly and how to influence it & training on making units business ventures and marketing results, and sustainability evaluation of the program. Results: Processing raw sugarcane into brown sugar allows partners to directly improve their economic conditions by converting sugarcane into semi-finished products, namely brown sugar that is ready to sell to the industry, especially the soy sauce industry. Conclusion: The processing of raw sugarcane into brown sugar can directly improve its economic condition by converting sugarcane into semi-finished products. And there are several factors that inhibit or tighten the manufacture of brown sugar. Keywords: Sugar cane, Brown sugar, Yield
