This research is presented by the designing and constructing test package that are divided into three types; the liquid insulator solid insulator and gas insulator. These materials are provided by in country in order to construct the test package for the results of expected to have at least error. This leads to reliability and validity in this study. The design of the liquid insulator of test package was conducted by the standard IEC 156 in which the material tested used oil transformer. Additionally its solid insulation was the range of catching objects and adjusting using the sheet of bakelite. Furthermore its gas insulation used acrylic was consisted of gas inside oxygen of pressure at 2 Bar. Three types of test could be supplied AC high voltage to test package causing of breakdown via insulators. After that taking note the value of breakdown was the liquid insulator of test material at 29.86kV its solid insulator at 36.32kV and its gas insulator (oxygen) at 48.40 kV

This research report describes the study of the development of finite element modeling for magnetoacoustic wave generation for non-destructive tomography. In the study the two-dimensional finite element model is used for the generation of magnetoacoustic wave in the mimic biological tissue model. The Gaussian pulse is applied as the excitation pulse in this research. The result of signal capturing at the boundary of mimic tissue model is used for the reconstruction cross-section image which is agreed to the original conductivity distribution.

This research aims to study the important factors that affect the decision making in the manufacturing process development of industrial factories according to the Industry 4.0 concept and to create decision models. The model developed from applying Analytic Hierarchy Process (AHP) to this group of experts focuses on the most strategy and organization factors accounted for 28.3 percent followed by the smart factory accounted for 17.8 percent smart products accounted for 16.3 percent smart operations accounted for 13.1 percent employees accounted for 12.5 percent and the data-driven services accounted for 11.9 percent by the model test results with 3 factories. In conclusion this model can decide the way to improve the production process of industrial plants according to the Industry 4.0 concept that is suitable for the context and limitations of each industrial plant can be used for all types of industrial plants and will directly benefit the decision makers of industrial plants to improve the production process and develop into smart factory based on the Industry 4.0 concept.

Nowadays brake pad is a one of products that plays a role in the automotive parts industry and directly affects safety. Therefore there are many designs of brake pad for product development. The technique of reinforcing the layer in brake pads is another option for developing such products. The objectives of this research are to solve the problem of noise from brake pads using the material layer reinforcement technique and raise the quality of brake pads to use in the industrial sector. As a result the prototype brake pads with reinforcement techniques by means of damping layer were performed. Consequently the experimental work reveals that the brake pads with damping layer technique for brake pads can reduce vibration and also brake noise at the same frequency at less 10 percent at braking speeds of 50 100 and 130 km/h. Besides this technique can be applied to the production of brake pads in the same formula. However the prototype brake pads is still in the product development phase for testing in a variety of conditions both temperature factors and usage period

Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This research presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.
