Abstract

Pada penelitian ini telah dilakukan perancangan sistem pemantauan parameter fisis air berbasis Internet of Things (IoT) menggunakan Raspberry Pi. Parameter yang dipantau pada sistem ini yaitu pH, temperatur air, kekeruhan air, dan ketinggian air. Parameter yang dipantau merupakan parameter yang penting untuk menentukan tingkat kualitas dan kuantitas air. Sensor yang digunakan adalah sensor suhu tipe DS18B20, sensor kekeruhan tipe SEN0189, sensor pH air tipe SEN0161, dan sensor ultrasonic HCSR04 trigger untuk ketinggian air. Perangkat lunak sistem yaitu program yang ditanamkan pada mikroprosesor Raspberry Pi. Mekanisme kerja dari sistem pemantauan yaitu sistem akan mendeteksi parameter fisis dari sensor, hasil sinyal dari sensor akan diproses melalui Raspberry Pi, dan data yang telah diproses tersimpan diserver yang bisa diakses pada web. Tingkat sensitifitas sensor yang didapatkan dari observasi terhadap sistem untuk parameter pH, kekeruhan, temperatur, dan ketinggian air masing-masing adalah 52,715 mV/pH, 0,0005 V/NTU, 0,0255 V/°C, dan 0,0583 milidetik/cm. Persentase ketepatan rata-rata yang didapatkan pada pengujian sistem adalah berkisar antara 96,86% sampai 99,9%. Ketelitian pada sistem berkisar antara 0,94 sampai dengan 0,99. Dari hasil pengujian ketepatan dan ketelitian maka sistem pemantauan parameter fisis air dapat bekerja dengan baik. Penelitian ini harapannya dapat menghasilkan sistem pemantauan parameter fisis pada air  yang berfungsi membantu pihak terkait untuk mengidentifikasi kualitas dan kuantitas air dengan mudah, efisien, dan akurat.

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.
