The structural statics course is one of the compulsory courses of FTMD ITB. This course is usually attended by approximately 389 first-year students. The learning methods used until now are still in the form of lectures and collaborative learning tutorials. Whereas, the learning process can be further improve if it were to be accompanied by practicum activities. However, the practicum devices that are available in the market are highly expensive. Therefore, this bachelor thesis aims to design, manufacture and test the truss structure apparatus. The bachelor thesis begins with conducting a survey of existing products, then making design requirements as DR&O. After that, the bachelor thesis was continued by designing the design of the hinge support, gauge bar, and the supporting components of the truss structure apparatus. Then, the gauge bar design was analyzed using ANSYS software to obtain the amount of strain, stress, and deformation. After obtaining the simulation results according to the design criteria, the bachelor thesis proceeds with the manufacturing of the apparatus by machining, wire cutting, and welding processes. After that, it will be tested using analog and digital methods. The test results obtained will be compared with theoretical values. The truss structure apparatus function properly when the measurement value is close to the theoretical value. The next step is to make suggestions for better prototypes and to establish a standard operating procedures (SOP) for practicum. In this bachelor thesis, the truss structure apparatus has been made in accordance to the DR&O. The apparatus has a mass of 6.2 kg, dimensions of 560 mm x 200 mm x 244 mm, and a loading range of 0-400 gf. The test results and theoretical values differ due to several factors, such as changes in configuration, tolerance dimensions of bar, and direction of forces that are not exactly as planned.
