Abstract

Sistem pengering tenaga surya ini digunakan untuk mengerigkan singkong yang telah diiris membujur setebal 2mm. pada penelitian ini sebagai pengumpul utama panas adalah kolektor berpenutup miring yang dihubungkan keruang pengering. Udara panas dikolektor bergerak keruang pengering dan dipercepat oleh ventilator. Penelitian ini dilakukan pada saat ruang pengering dalam keadaan kosong suhu terendah 42.50C terjadi pada dulang 3 saat jam 09.00 WIB dan tertinggi 50.50C di dulang 2 pada jam 12.00 WIB. Bahan yang dikeringkan adalah 500 gr singkong dengan kandungan air 56.1 %. Massa bahan didalam ruang pengering setelah tiga hari pengamatan adalah 219.5 gr dengan kandungan air 2.73 % dan diluar ruang pengering bermassa 241.8 gr dengan kandungan air 5.9 %.

Abstract

Letak astronomis Indonesia yang dilewati oleh garis khatulistiwa memberikan potensi yang sangat baik dari sumber energi surya, sumber energi ini dapat dimanfaatkan dalam berbagai aspek kehidupan salah satunya untuk daur ulang air kotor. Indonesia sebagai negara maritim yang memiliki luas daerah perairan sekitar 62,89 % luas Indonesia, tetapi hal ini tidak menjamin banyaknya sumber air bersih yang merata disetiap daerah. Alat daur ulang air kotor tenaga surya dirancang untuk menghasilkan air bersih, dengan memanfaatkan radiasi matahari yang diserap oleh kolektor pelat datar maka akan membantu proses penguapan air kotor yang diletakkan dalam bejana tepat di atas kolektor, sehingga akan menghasilkan uap air dan terkondensasi membentuk butir-butir air (kondensat) yang menempel pada permukaan penutup alat yang terbuat dari kaca sehingga dapat dialirkan ke penyimpanan air yang sudah bersih. Volume air bersih rata-rata yang dihasilkan setiap jam adalah 217,5 ml dengan suhu sekitar 37,2 oC dan intensitas cahaya matahari yang mengenai tutup kaca sebesar 350 Cd. Air bersih yang dihasilkan ini tidak dapat dikonsumsi langsung oleh tubuh manusia dan perlu diolah lebih lanjut dengan proses kimia. Kata kunci: Daur ulang air, Tenaga surya, Kolektor pelat datar.

Abstract

This study used TCS 230 as color sensor to create colors’ album by identified output frequency of TCS 230 and measured RGB value for each color. TCS 230 converted light to electric signal by wave frequency. By using colored paper and facing to TCS 230, the LabVIEW presented its RGB value. From measurements taken, it appears that the sensor have been able to read the color, not just the primary colors (RGB) but also its derivatives. Sensors indicate that despite differences derived by naked eye color and RGB composition has only minor differences, the fixed sensor is capable of capturing the difference even though there are still errors. The amount of the average error for the color red and its derivatives is 28.0336%, while the average error in the measurement of derivatives and their blue color is 38.96% and the average error in blue and derivatives amounted to 32.99103%. Keywords:RGB,TCS 230, labVIEW, colors’ album.

Abstract

The astromi indonesia traversed a line equator Provides the potential for maximum solar energy, this energy source be used to recycle water. Indonesia as a country maritime had area of water 62,89% from area of Indonesia, but this fact does not guarantee the large number of clean water supplies in each region. The instrument recycle water with solar energy designed to produce clean water be used solar radiation absorbed by flat plate collector will Help the process of evaporation dirty water A container at the top of a collector, So that will yield water vapor and the condensed form the grain of the water (condensate) On the surface of cover collector, so Of the water where they cleansed and pruned already can be funneled into a clean water storage. The rate of volume clean water every hour is 217,5 ml with temperature 37,2oC and The intensity of sunlight on cover collector is 350 Cd. This clean water can not be consumed by body and Need to processed further by a chemical process.

Abstract

Replating the ship’s hull is an essential repair process to ensure that a vessel remains operationally seaworthy. Replating welding can be performed under both docking and floating conditions. These differing conditions influence the cooling rate, which in turn can result in variations in hardness (HV). This study examines the effect of varying the distance from the waterline (30, 60, 100, and 130 mm) and water temperature (25°C, 28°C, 30°C, and 32°C) on the hardness values produced during welding under floating conditions.Each variation combination was tested using the Vickers method with three repetitions, and the reported HV values represent the average of those measurements. The results show that the highest hardness value under floating conditions reached 218.5 HV (30 mm, 25°C), while the lowest was 195.7 HV (130 mm, 32°C). All measured hardness values remained within the acceptable limits specified by BKI for low-carbon steel.This study demonstrates that the closer the weld groove is to the water surface and the lower the water temperature, the higher the resulting hardness due to increased cooling rates. The limitations of this study include the absence of microstructural data and the unavailability of individual measurement data for further statistical analysis.
