Abstract

The production of Dye Sensitized Solar Cells (DSSC) has been done. The transparent electrode is made by mixing of TiO2 and graphite 14% (TiO2:C14%). TiO2:C14% colloid is deposited on a conductive glass substrate Fluorine Doped Tin Oxide (FTO) by spin coating method at 500, 1000 and 1500 rpm during 50 second. Then, the layer is soaked of 24 hours in dye taken from the extract of rosella. SEM and XRD characterization are performed for looking properties of DSSC materials. The efficiency of DSSC is calculated by using the characteristic circuit IV curve. The highest efficiency value is obtained when the thickest active layer (0,9 mm) at 500 rpm, the resulting efficiency is 0,014%.

Abstract

The collimator test is one of the X-ray Quality Control (QC) program, one of the central point beam testing and the area of the collimator beam using the RMI unit. The purpose of the collimator test is to find out the suitability of the broad field of collimator with the area of X-ray beam in tolerance of ≤ 2% Focus Film Distance (FFD) and the correspondence of the X-ray center point in tolerance Ɵ = 3˚ as determined by the Minister of Health Decree No . 1250 / SK / XII / 2009. The study was conducted using variations of FFD at 100 Cm, 90 Cm, 80 Cm, on three X-ray radiation radiology radiation RSUD Raden Matther Jambi. In this study using digital radiograph unit (DR) or computed radiographaphy, no longer using conventional radiographs such as previous studies. Irregularities or wide discrepancies in the area of the X-ray beam are evaluated by evaluating the firm boundary of the line formed by the X-axis and Y-axis, then determining the midpoint between the line boundary and the radiation boundary of the scatter. The deviation results concluded that there was no deviation at the central point of X-ray beam for all X-ray aircraft tested by all aircraft still within the tolerance threshold Ɵ = 3˚. But for the value of the collimator area all the X-ray macine tested has deviations exceeding the predefined 2% FFD threshold where the radiologie france plane occurs deviation on the Y axis with FFD 90 Cm and 80 Cm, hyundai medicaly X- ray on X axis with FFD 100 Cm and 80 Cm, Y axis with FFD 80 Cm, and on villa sistei medicali SpA plane on X axis with FFD 80 Cm, Y axis at FFD 80 Cm.

Abstract

Increasing of electrification in Indonesia still leaves several problems, such as blackouts. This can be caused by greater demand than energy availability. Businesses that can be taken to overcome this problem is include making an arrangement on the consumer side or demand side management (DMS). By implementing control technology, an Arduino-based embedded system device has been able to measure electricity consumption. The application of the TA12-200 current sensor has been able to measure electricity power with accuracy up to 96.4% and sensor resolution for about 0.4 volts per ampere. This system is equipped with an RTC module to calculate the duration of measurement, then convert the value of power (watts) into electricity energy (kWh) as well as the electricity cost in rupiah. Displaying the cost of electricity in rupiah, in this measurement system, is considered has a potential to increase user awareness to make savings on electricity usage. This is able to reduce the electricity demand, thus the cases of blackouts can be minimized.
