Estimation Model on Electricity Generation from Solar Energy

The Solar Energy is produced by the Sunlight is a renewable source of energy which is eco- friendly. Every hour enough sunlight energy reaches the earth to meet the world’s energy demand for a whole year. In today’s generation we needed Electricity every hour. This Solar Energy is generated by as per applications like industrial, commercial, and residential. In this article, we have reviewed about the Solar Energy from Sunlight and illustration given to estimate the parameters for solar energy set up.

Hydrolysis synthesis route for (001)/(102) coexposed BiOCl nanosheets with high visible light-driven catalytic performance

RANCANG ALAT PEMURNI AIR LAUT TENAGA SURYA DENGAN KOLEKTOR PANAS CERMIN CEKUNG

Tujuan dari penelitian ini adalah: merancang alat pemurni air laut berdasarkan teori pemanasan, penguapan dan kondensasi menggunakan energi sinar matahari. Kegiatan penelitian dilakukan dengan mengamati data parameter berdasarkan 3 kombinasi perlakuan, yaitu; a) penggunaan kotak evaporasi yang memurnikan air setinggi 1 cm; b) penggunaan kotak evaporasi dan cermin cekung yang memurnikan air setinggi 1 cm; c) penggunaan kotak evaporasi, cermin cekung, dan kondensor yang memurnikan air setinggi 1 cm; Pengamatan selama 10 jam pemanasan di bawah matahari mulai pukul 07.00-17.00 WIB, memberi hasil bahwa ketiga kombinasi tersebut mampu memurnikan air laut menjadi air tawar. Kombinasi terbaik adalah kombinasi B, yang menghasilkan volume air tawar sebanyak 1.718 ml. Pengamatan lain yaitu nilai TDS menunjukkan bahwa penurunan nilai TSD air baku (air laut) dari 27.000 ppm menjadi 3 ppm hingga 5 ppm, sedangkan suhu air yang dihasilkan dari proses pemurnian menunjukkan nilai-nilai berkisar antara 27,5oC hingga 29,7oC, sedangkan pH air destilasinya berkisar di 5,024 hingga 5,252. Kata kunci : Air Bersih, Energi Surya , Pemurnian Air. The purpose of this research is : designing a water sea purifier tools based on the theory of heating, evaporating and condensing using sunlight energy. The research activity is done by observed data parameter based on 3 combination of treatment ; a) the use of evaporative boxes to purify seawater as high as 1 cm; b) the use of evaporative boxes and concave mirrors to purify seawater as high as 1 cm; c) the use of evaporative boxes, concave mirrors, and condensors to purify seawater as high as 1 cm; Observations for 10 hours of warming under the sun began at 07:00 to 17:00 pm, giving resulted that all combination are able to purify the seawater into fresh air. The best combination is a combination of B, which produces a fresh air volume of 1,180 ml. . The observation of the TDS value shown that a decline in the value of TSD raw water (seawater) from 27.000 ppm to 3 ppm until 5 ppm, while the temperature of the water produced shown values range between 27,5oC up 29,7oC, whereas pH of the destilated water around the 5.024 up to 5.252.

Near infrared harvesting dye-sensitized solar cells enabled by rare-earth upconversion materials

Dye-sensitized solar cells (DSSCs) have been deemed as promising alternatives to silicon solar cells for the conversion of clean sunlight energy into electricity.

IDENTIFIKASI TANAMAN BERDASARKAN TIPE FOTOSINTESIS PADA BEBERAPA SPESIES ANGGOTA GENUS FICUS MELALUI PENGAMATAN ANATOMI DAUN

<em>Photosynthesis is the process of carbohydrate synthesis of inorganic materials in plants pigmented with the help of sunlight energy. Based on the type of photosynthetic plants are divided into three kinds, namely C3, C4 and CAM. More adaptive C3 plants under conditions of high atmospheric CO₂ content and do not have vascular sheath while the C4 plant more adaptive hot and dry areas, have a vascular sheath cells which are well developed and contain chloroplasts when observed anatomic structures. The purpose of this study was to identify plants by type of photosynthesis in Ficus callosa, F. elastica, F. benjamina, F. fistulosa, F. septica, F. rubiginosa and F. pisocarpa through leaf anatomical observations that cut transversely. The results showed that F. elastica and F. callosa have well-developed sheath cells surrounding the xylem and phloem, while F. benjamina, F. fistulosa, F. septica, F. rubiginosa and F. Pisocarpa are not</em>

Understanding the Thermodynamics of Biological Order

By growth in size and complexity (i.e., changing from more probable to less probable states), plants and animals appear to defy the second law of thermodynamics. The usual explanation describes the input of nutrient and sunlight energy into open thermodynamic systems. However, energy input alone does not address the ability to organize and create complex structures or explain life cycles – in particular, growth regulation and dying in the presence of adequate nutrients. Understanding the roles of macromolecules such as DNA, with their apparent information-processing capability, affords opportunity to understand biological order.
