Abstract

A gas emmision decent testing of vehicles based on fuel has been done by EIA (Environmental Impact and Analysis). It is important to do the testing to determine the vehicles meet the technical requirements and road-worthy. The results showed that for 1.572 vehicles which is performing emissions testing have obtained 11% that could be potentially pollute the air on vehicles that using gasoline, and 42% on vehicles that using diesel. Based on the total number of four-wheeled vehicles that performed emissions testing in the city of Banda Aceh showed that 82% environmentally friendly vehicles and 18% potentially pollute the air.

Abstract

Anomalous Amplitude Attenuation (AAA) is a method to process seismic data with multilevel processing (multi step flow). AAA is indicated for identifying anomalous seismic amplitude (amplitude noise) such as: spike noise, noise and noised trace. AAA is a filter applied to the data in the frequency domain, range, both in CMP/CDP, offset or gather shot. Processing of the data depends on how the sensor (the geophone) receives seismic waves, and then set the data back into the format demultiplex (SEG-Y) and then processed according to the rules (flowchart) seismic reflection processing.This method has been applied to improve the old seismic data of an exploration company in prospecting the unseen structure in prospecting the hydrocarbon trapped within sedimentary rock subsurface.

Abstract

The study of rainwater quality measurement has been done in brick manufacturing area of Kajhu, Aceh Besar. The measurements are taking place in the three different places when the rain fall from the sky in Kajhu area. The physical parameters that will be measured are pH, TDS, conductivity and potential of electricity.

Abstract

A simple and compact sensor has been designed for measuring a viscosity of a fluid. The sensor consists of a magnet and a curved thin wire made of copper. The function generator supplies a frequency and the voltage output was reading by the lock-in amplifier. The measuring voltages were analyzed by the curve fitting method numerically.

Abstract

Properties of (Bi, Pb)2Sr2Ca1Cu2Oy ceramic superconductors were prepared by the melt textured growth methods in order to investigate the effects of the slow cooling time on the microstructur.  Phase analyses of the samples by X-ray diffraction (XRD) has been carried out to assess the effects of the slow cooling time. From XRD analyses, the addition to the sample of  the slow cooling time degrades formation of the high-Tc Bi-2212 phase. The possible reasons for the observed degradation in the microstructure properties due to the slow cooling time addition were discussed.

Abstract

A security alarm for motorcycle has been developed. This equipment consists of two parts. Part one is as a remote control, where it produces a radio signal with frequency of 37.5 MHz to turn on (activate) or to turn off alarm. Part two consists of sensor, receiver to receive signal from part one, and alarm. This part two will be attached to motorcycle while part one will be kept as a key by the owner of motorcycle. This equipment has been tested in the laboratory and it worked well. When part two is activated by pushing the “set button” in part one, then any movement of part two (as a movement of motor cycle) by about 20 cm from initial position will cause the alarm sounds continuously. The alarm will be off whenever the “reset button” in part one is pushed. Part one (a remote control) can activate part two with a maximum of twelve meter separation apart. This shows that the equipment can be used as a security alarm to prevent the motorcycle to be stolen in the future.
