Abstract

The Energy and Environmental Engineering Laboratory had a heat exchanger simulator which was used to determine the temperature changes with respect to time due to air velocity. This simulator used tubes which were used to find out the temperature change with time. The working principle of this simulator was to monitor changes in temperature on the tube that had been preheated and then cooled using a fan contained in the simulator. This study performed temperature measurements using a TPA81 thermal array sensor. We chose this sensor because it could measure the temperature without touching the object and had 8 pixels for image measurement. This was because the process of reducing the temperature of the tube becomes purely caused by the fan and not from the outside environment. The results obtained from this study were visualization of temperature distribution using the Thermal Array TPA81 sensor, having a linearity value of 0.034%, a precision value of the instrument of 98.1%, an accuracy value of 0.285%, and error value of 0.154 (W/m2K). For the analysis of temperature distribution, it was concluded that the value of the temperature did not affect the value h, because the value of h (the coefficient of heat transfer convection) is distributed with time.

Abstract

Earthquake Shaking Table (EST) is a device which can simulate an earthquake motion. This device is used to test the strength of a building structure against an earthquake motions before it’s actually made. EST uses a variety of actuators one of them is ball-screw linear guide actuator. The EST used in this project is a bi-axial type which uses 2 linear actuators to simulate the x-axis and y-axis movement of earthquake, each of them used bipolar stepper motor as the main rotary-actuating device. This project models the linear guide actuator using backpropagation neural-network algorithm. The model is built with empirical method using datas taken from the real behavior of both linear actuators. The datas include acceleration, displacement, and velocity of both actuators and they are used to train the neural network using backpropagation with Levenberg-Marquadt method. Simulation is done using Simulink and the results show that model is able to produces nearly same exact movement with the real hardware with error approximately 0,214 % and 0,685% respectively for both actuators.

Abstract

Sinan Village is located in Karangbinangun Subdistrict, Lamongan city, which is experiencing a shortage of clean water. The main source of water for the people in that village is originated from river water of Bengawan Solo branches which is mixed with pond water and is collected in a pond. The results of the pH, turbidity and TDS tests that have been carried out show that the Bengawan Solo water does not meet WHO's clean water standards and the standard from Ministry of Health. In this study, the design of the river and pond water filtration control system in the reservoir was carried out. The designed filtration system consists of the deposition stage and filtering stage. Deposition stage is carried out by using alum as a purifying medium and aims to simplify the screening phase. While the screening stage is carried out using stone, sand, charcoal and palm fiber which aims to increase the pH value and reduce the value of turbidity and TDS. The system is designed in a modular manner between each filtration stage to fascillitate the maintenance process of the system and flushing the remaining deposits produced by the filtration process. Testing result of this system is done by varying the variables of volume and height of sand used and it is known that the difference in sand volume used has a significant effect on the levels of TDS, Turbidity, and pH of the resulting clean water.
