In the industrial world, companies are required to be more effective and creative with the development of today's technology. Transverse ducting flange (TDF) machine is a machine that functions to make ducting flange products and form ducting connections, where there are several components in large quantities, so the design of the frame construction made must be strong to support these components. Responding to the cases that occurred, with the aims and objectives of this study, namely to determine the level of efficiency in the use of the design on a hollow galvanized steel frame measuring (100 × 50 × 3,2) mm, by performing simulations using SolidWorks Premium 2019 software with static analysis features. using the finite element method. So with this research, we can find out whether the frame is receiving loads that exceed the yield strength limit or vice versa. The results of the research are three load-bearing areas received, with load values in a row, namely 11693,809 N, 266 N, and 598,206 N. From the results of the three, it shows that the design of the frame construction that has been made is safe to use, because the calculation of the analysis meets the value requirements safety factor and the maximum stress simulation that occurs does not exceed the yield strength limit of the frame material.

The test chamber in an open-loop wind tunnel is a critical part for aerodynamic experiment. The study aims to assess the feasibility of the new design of test chamber for open–loop wind tunnel by studying the fluid characteristic and the average pressure in the test chamber. The study is done by a series experimental test for the test chamber. From experimental test, the downstream velocity in the test chamber is increased from 8.9 m/s to 12.72 m/s where the pressure gradient is ranging from 6.19 to 8.398 atm with the overall turbulence intensity for the test chamber is 0.749%. According to the results, the designed open-loop wind tunnel is acceptable to use for an aerodynamic test.

The Micro Gas Turbine is a device that functions to convert chemical energy from fuel from the combustion process into mechanical energy, which is then converted back to a generator to become electricity. This study aims to obtain the results of performance testing as well as the results of the comparison analysis of the Gas Turbine Micro from the design and testing of the assembly tool. The fuel used in this Gas Micro Turbine is LPG (Liquefied Petroleum Gas). The advantages of LPG are it is easy to obtain, has a high octane value so that the power generated is greater, has a high vapor pressure so there is no need to use a pump to drain it. The result of this research is that the addition of a fire source can increase the turbine inlet temperature although it is not significant because the fire does not burn continuously due to the compressor rotation being too forceful. In the first and second actual tool tests, the temperatures were 317.48 K and 323.75 K, different from the results of the analysis on the ANSYS software where the temperature was 766 K and 793 K.
