Abstract

Shaker excitation in FRF (Frequency Response Function) measurement of a testing system can be controlled by using swept-sine signal source in a signal generator and it is called with swept-sine excitation. FRF’s magnitude error of the system which is obtained from the FRF measurement using swept-sine excitation depends on swept function of swept-sine signal. In this paper, swept-sinesignals using linear and S535 swept functions have been simulated to controlling swept-sine excitation in the FRF measurement of SDOF (Single Degree of Freedom) system. Linear swept is swept function of swept-sine signal which is often used in the FRF measurement and S535swept is a swept function has been developed in this paper. Based on simulation results, the FRF’s magnitude error at system’s resonant frequency which was obtained from the FRF measurement using linear swept-sine excitation can be minimized by redoing the FRF measurement using S535 swept-sine excitation.

Abstract

The The Republic of Indonesia is rich in potential for renewable energy, including abundant wind energy. This study aims to design a subsonic open return wind tunnel for testing wind turbines at low airspeeds. The testing focus includes the evaluation of blade efficiency, bearing performance, and other aspects. Testing at low airspeeds (<5 m/s) is highly relevant to the wind conditions in Indonesia. The design process utilizes Computer Aided Design (CAD), while data collection and analysis are conducted through Computer Aided Engineering (CAE) simulations and theoretical calculations. The wind tunnel comprises components such as contraction, honeycomb, test section, diffuser, and support structure. Airflow over the turbine blades can be observed using smoke visualization in the test section. This research is expected to provide practical contributions to the development of low-speed wind turbines in Indonesia.

Abstract

This study aims to determine the effect of setting the firmware on the time and results of the engraving and to analyze the impact of the engraver variable on the CNC Laser Engraving machine. The test results of the cnc laser engraving firmware setting were obtained from several stages of testing the predetermined settings such as the Axis maximum rate and Axis acceleration settings, in order to find the appropriate Axis maximum rate and Axis acceleration settings for the laser engraving process. Tests with the Axis maximum rate setting are carried out with variables 600 mm/min,1200 mm/min,1800 mm/min aiming to find the ideal speed, Tests with Axis acceleration settings are carried out with variables 20 mm/s2, 40 mm/s2, 60mm/s2. aims to find the ideal acceleration by looking at the stability of the results and comparing the test data. axis maximum rate ($110 and $111) 600 mm/min and axis acceleration ($120 and $121) 40 mm/s2, taking into account the engraving time and the resulting clean, non-blur engraving results and the resulting engraving line width. Based on the study, it is recommended for users to be careful in setting the firmware for maximum and clean results. Based on the speed and acceleration test data on the engraving scale, the faster the engraving process, the smaller and blurry the resulting scale (width of the engraving) will be.

Abstract

Material is needed in life, the material itself is used aims to facilitate human activities, in the development of modified human material in various ways, one of which composite materials. Composite is a combination of two or more elements that get combined properties of the elements combined. Liquid Epoxy resin is a low molecular weight organic group containing epoxide. The composite material used is a fiber reinforced resin nut shell. Point of this study is know tensile strength of fiber nut shell composite, variations in the composition of the epoxy resin and fiber nut shell made in this study was 90:10%wt, 80:20%wt, and 70:30%wt, fiber length of 2 cm with random fiber orientation. This experiment is the tensile test. Tensile test was conducted to determine the tensile stress each - each composition, the standard used is ASTM 638 02. From the test results obtained on the composition of the composite tensile strength of 90: 10% wt is 9.8 MPa, the composition of 80: 20% wt was 13.06 MPa and the composition of 70: 30% wt is 14.04 MPa. Of the fracture surface can be seen that the fibers are well distributed and the bond between resin and fiber is also more evenly so that the tensile strength increased.

Abstract

This research aims to determine the effect of laser settings on the engraving results of a CNC Laser Engraving machine on plywood media. Controlling the movement of the CNC laser machine spindle using Arduino UNO. Testing was carried out by setting the laser power (S-Max) scales are 100, 200, 300, 400, 500 and 600. Position variations of laser head above the plywood media are 3 cm, 5 cm and 7 cm. The test results show that low S-Max scale will produce unclear dotted lines if graving the circle shape and the greater S-Max scale, the thicker the line will be. The lower position of the laser head above the surface of the plywood media, the wider the graving size (engraving line width). The best engraving results were obtained with S-Max scale is 400 and position of laser head above the plywood media is 5 cm with fairly stable and clear engraving lines.

Abstract

Water is a source of life, but it is very easily polluted because water is known as a universal solvent and is able to dissolve many substances. Water pollution is the pollution of water bodies (seas, lakes, rivers, groundwater) caused by human activities. To obtain water that meets water quality standards, it must be supported by an appropriate water treatment system, one of which is the water treatment tool in this research, called AFRO. AFRO works with a reverse osmosis filtration aeration process. Previously, AFRO was developed to treat raw water containing dissolved impurities. However, the results are less than satisfactory, so it needs to be developed further to meet the need for clean water that can be utilized by the community. The development of AFRO in this research is based on the House of Quality (HQ) matrix. From this HQ matrix, a presentation of development priorities was obtained from the previous one in the form of design changes of 16.1%, material changes of 9.6%, processing processes of 14% and energy changes of 9.2%. From the tests that have been carried out, this time AFRO can process raw water from dissolved and insoluble impurities. This tool is also equipped with a solar energy utilization system. The AFRO water treatment process developed consists of (1) chemical process, (2) aeration, (3) filtration, (4) reverse osmosis and (5) disinfection using ultra violet (UV) light.
