Abstract

 Penelitian tentang stepwedge berbahan kayu lokal sebagai phantom yang dipapar oleh pesawat sinar-X telah dilakukan. Tiga jenis kayu digunakan yakni Seumantok (shorea macroptera), Meranti Merah (shorea leprosula Miq) dan Medang Kuning (dehaasia cuneata). Uji sifat fisis kayu berupa kadar air dan kerapatan telah dilakukan terhadap ketiga jenis kayu tersebut. Kadar air terendah terdapat pada kayu Seumantok (10,1%), sementara kadar tertinggi pada kayu Meranti Merah (12,3%). Kerapatan tertinggi didapatkan oleh kayu Meranti Merah (0,9 g.cm­-3) dan terendah pada kayu Medang Kuning (0,6 g.cm­-3). Standar Aluminium stepwedge digunakan sebagai salah satu referensi pengujian. Paparan pesawat sinar X terhadap stepwedge tersebut dilakukan pada dua rumah sakit besar di kota Banda Aceh dengan perbedaan arus dan tegangan untuk memperoleh hasil citra yang tajam. Hasil penelitian menunjukkan bahwa untuk tegangan dan arus yang berbeda akan menghasilkan hasil citra yang berbeda pula pada dua buah rumah sakit tersebut. Untuk stepwedge berbahan kayu citra terbaik dihasilkan pada tegangan rendah.Research on stepwedges made of local woods as a phantom that will be exposed to X-ray machine has been done.

Abstract

This paper presents an experimental study to support the concept of generating energy by a continuous flow of water using piezoelectric sensors. This study is aimed to determine the effect of external force direction of continuous water flow, i.e., vertical and horizontal, on the output of the piezoelectric sensors. The piezoelectric type of ABT-441-RC is used and arranged in parallel. IC MAX471 as an amplifier and Arduino Uno R3 to read the flow rate, voltage, and current were employed. Flow rates with variations of 0.00011 up to 0.00030 m3/s are set to study the voltage and current of the output. The numbers of piezoelectric sensors used are 4, 6, 8, and 20. As a result, it is found that the pressure in the vertical direction differs up to 68% from the pressure in the horizontal one. The voltage and current in the vertical direction, compared to that of the horizontal direction, differ as much as 85% at a low flow rate and decrease down to 63% at a high flow rate for voltage and 86% to 34% at a low to high flow rate for current. In conclusion, the current generation by the present arrangement is within the micro-ampere range, and the voltage is in a volt range, respectively.

Abstract

An important factor in the development of nuclear energy is reactor safety. The performance of heat transfer from nuclear fuel to coolant is the main key to the reactor safety. This paper presents simulation on temperature distribution in two-dimensional laminar flow for single pellet thermal reactor with variation on temperature inlet and mass-flowrate. The OpenFoam platform (SimFlow 3.1) has been used for the computational and numerical analysis. The simulation is carried out on a single pellet with an aspect ratio of 1.2. The variations in the mass velocity of the coolant flow are 10, 100, and 14300 kg×s-1 with a constant coolant temperature of 552 K, and the variations of the input coolant temperature are 300, 552, and 1000 K with a constant mass-flowrate of 10 kg×s-1. The results obtained from the simulation show that for variations in the input coolant temperature of 300, 552, and 1000 K, the fuel temperature can be reduced respectively by 34, 26, and 14 K. At the fastest variation in the coolant mass-flowrate of 14300 kg×s-1, the coolant temperature around the pellet rises by 396 K. The decrease in fuel temperature is significant if the mass-flowrate of the input coolant flow is relatively low.

Abstract

The use of the notorious synthetic dye, rhodamine B, in food and beverage products has been widely reported. This application urges the need to develop an analytical method that can provide reliable rhodamine B data with an easy operational technique. Therefore, this research is aimed to develop an Arduino Uno-based TCS3200 color sensor and study its application to determine rhodamine B levels in syrup. The design of the analytical instrument included TCS3200, an Arduino Uno microcomputer, an Integrated Development Environment (IDE) software, a black box container, and a 24 × 2 matrix display screen, where samples were prepared via absorption using wool thread. With a linear range of 1–20 mg/L, our proposed colorimetric sensor had recoveries of 96.25–110.3%, which was better compared to that was obtained from the UV-vis (81.8–100.6%) method. The detection and quantification limits of the sensor were 2.766 and 8.383 mg/L, respectively. The syrup samples used in this study were purchased from the local stores in Banda Aceh. Based on the proposed TCS3200 color sensor, the highest rhodamine B concentration from the syrup sample was 16.74 mg/L. The t-test analysis in this study revealed that the Rhodamine B levels quantified using the newly developed TCS3200 color sensor were not statistically or significantly different from the UV-Vis spectrophotometer method.
