Eddy current test (ECT) is one of the techniques for accurate testing as well as widely used in the aircraft and nuclear industry. Changes in thickness due to corrosion will affect the measurement of defects on pipes or plates. This will make an irrelevant decision as to whether the defect that occurs on the work piece is the thickness of the paint or corrosion. This problem can lead to the occurrence of leaking pipes, apart from the deterioration of the company’s productivity and most importantly endangering the safety of employees. Meanwhile, eddy current testing is one of the methods in NDT used to detect cracks or corrosion on the surface of carbon steel. In this work, GMR Eddy Current sensor is used to measure the corrosion on carbon steel pipes, and a permanent magnet is used to generate the magnetic field for corrosion detection. Also, this system is configured with an IoT Unmanned Aerial Vehicles (UAV) drone platform to facilitate access at different heights during the inspection process. The change of voltage amplitude at the GMR sensor on the test material proves the conditioning of the material either normal or corrosive. The result shows that when corrosion occurs on the pipe, the voltage amplitude increases up to 0.5% higher than normal. Finally, the metal loss is higher when the corrosion area is larger and at the same time it is directly proportional to the voltage amplitude

Jigs and fixtures were brought to the world of machining, bringing a variety of practical purposes. The concept enables rapid mass production of the same product. Thus, the company will streamline the manufacturing process for each component and boost productivity. At times, the machining operation was carried out entirely by the machine, without jigs and fixtures. As a result, jigs and fixtures were created to expedite the drilling process. The project's objectives are to design a jig and fixture, fabricate it, and analyze the performance on a square block of wood. The structural model for drilling jigs and fixtures was created using the Inventor Professional 2019 Computer-Aided Design Software. The fabrication process used were milling, surface grinding, CNC wire-cut, and drilling machines. Aluminium 1065 was utilized because it is less expensive, lighter than other materials, and easy to process. The result demonstrates that a hole can be drilled quickly using the jigs and fixtures. Preparing the hole with a jig and fixture takes only 1.28 minutes, compared to 3.45 minutes with a table drill. The advantages of this product are the time operation can be reduced and quickly operations on the drilling process.
