Abstract

Underground water is one of the important component sources for human being. Study on interpretation of underground water flow has been carried out using Geoelectric Schlumberger Electrode Configuration in Labuh Baru Barat Village, Payung Sekaki District, Pekanbaru. The range measurement was chosen to be 240 meter. The output of measurement  arecurrent and voltage. The data, then was inputed into software progress and surfer 11. The output of this computer program is a map of underground waterflow  pettern and underground lithology. The results of mapping of the pattern of underground water flow indicate that the direction of water flow from North to South direction, or from Pinang street to Payung Sekaki street. The thickness of the layer start  from the first layer that is 4.05 meters and 5.4 meters is a layer of silt- clay, the second layer is 13.07 meters and 14.3 meters is a layer of mud stone, the third layer is 13.07 meters and 15.2 meters is a layer of sand and alluvial and the fourth layer is 51.1 meters and 79.2 meters is layer of gravel sand.

Abstract

The thin film of Barium Strontium Titanate (BST) has been studied withcomposition ofby using sol-gel method that annealed in temperature of 600oC and 650oC. The thin film of BST is characterized by using Field Emission Scanning Electron Microscopy (FESEM) and an impedance spectroscopy. The results of  FESEM characterization for samples in temperature of 600oC and 650oC are 55.83 nm and 84.88 nm in thickness respectively. The result of impedance spectroscopy characterization given frequency values obtained by the impedance value of real and imaginary.The capacitance value at a frequency of 20 Hz from a thin film of BST in temperature of 600oC and 650oC are 69.36Fand138.70F. The dielectric constant of the thin film of BST in temperature of 600oC and 650oC are 22.17 dan 131.56 respectively.

Abstract

Research on the utilization of coconut shell biomass waste for clothes dryer technology based on Arduino Uno has been carried out using the experimental method. This Arduino Uno-based dryer technology uses biomass energy from coconut shells with a mass of 2,000 grams for thin clothes and 4,000 grams for thick clothes. Observations were made based on the amount of coconut shell mass and the type of clothing used at 10 minute intervals. The results for a mass of 2,000 grams of coconut shell reached the highest temperature value with an average source temperature of 61.32°C, an average temperature in the drying chamber of 54.53°C with a minimum humidity of 19.5%, while the results for a mass of 4,000 grams coconut shell reached the highest temperature value with an average source temperature of 100.46°C, an average temperature in the drying chamber of 94.62°C with a minimum humidity of 21.1%.
