Stroke is a disease or functional disorder of the brain in the form of nerve paralysis due to obstruction of blood flow to the brain which can be completely cured, cured with disabilities, or death. Rehabilitation is an effort to improve the quality of life of stroke survivors. However, rehabilitation with self-therapy has several drawbacks such as relatively expensive therapist costs, scheduled time, and limited resources. Therefore, technology is needed such as an exoskeleton robot that can be used by patients for therapy independently and practically. An exoskeleton robot or stroke therapy robot is a robotic framework system that is worn on the patient's joints to assist the patient in the rehabilitation process. For exoskeleton robots there are several kinds of mechanisms and for this study a cable and sheet transmission mechanism is used which is where the drive motors are separate so that they don't put too much of a burden on the user's hands. This research focuses more on the design of the index finger robot which represents the middle, ring, and little fingers. The method used is ansys rigid body dynamic simulation analysis by looking at position, speed, and acceleration. From the simulation results on the index finger exoskeleton robot design, the Range of Motion (ROM) of the flexion extension movement of the MCP joint is 62.17°, PIP 68.74°, and DIP 73.98°. The speed and acceleration of the three joints adjust the position and time coordinates that have been set during the simulation.

The machining process is a process used in the manufacturing industry, the machining process itself has become an important part of the manufacturing industry since the industrial revolution era. In the machining process that is widely used to produce cylindrical products, namely the lathe process. One of the main factors of the quality of processed materials is surface roughness. MQL is a method of providing coolant in the industry which has the function of lowering temperature and reducing friction between the tool and the workpiece. The problem that often occurs in the industrial world, especially manufacturing in the turning process, is the mismatch of the surface roughness of the turning results. Where one of the causes of the roughness results to be inappropriate is the machining parameters that are not adjusted and the high temperature of the workpiece that rubs against the tool during the turning process. Therefore, it is necessary to optimize the machining parameters and coolant used in order to obtain efficient machining parameters and coolant that produces low roughness. The purpose of this study was to determine the effect of variations in the spindle speed parameter and the composition of the coolant mixture, namely clogged oil, dromus and water on the surface roughness value of AISI 1045 steel. From the experiments conducted it was stated that the optimum level of each parameter for surface roughness was level 3 spindle speed 585 rpm and level 3 composition of the coolant mixture 30% clogged oil : 20 dromus : 50% water. The parameter that has a significant effect on the value of surface roughness is the spindle speed.

Transportation in Indonesia has targets in getting their respective passengers, such as land, sea and air transportation. In air transportation, passengers as consumers or customers, are directly related to the facility service provider, namely the airport. With the increasing number of passengers using facility services at the airport, making the airport also participate in improving performance to provide the best service for its consumers. Waiting room or gate facilities are one of the services presented by the airport to consumers, in this case passengers, to be a waiting room before the departure time of the aircraft arrives. Some of the ideal conditions required by an airport to provide waiting room facility services are a short distance to get to the plane, a waiting room capacity that is directly proportional to the number of passengers and a fairly well allocated gate assignment, adjusting the existing flight schedule every day. This research is to analyze the risk factors that influence the buildup of the number of passengers at the gate which is affected by the time of an airline's on time performance and gate assignment

The use of composite materials as a substitute for metal materials in the engineering field has become increasingly widespread not only in the field of transportation panels but also in other fields such as property and architecture because alternatives have the advantage of using composite materials to be lightweight, corrosion resistant and strong and can be designed as needed. One of the methods developed to manufacture composite polymers is resin infusion with vacuum assistance. This method is inversely compared to the non-vacuum method. The (VARI) process requires an airtight space in printing and can reduce the fouling effects that occur in non-vacuum processes such as causing a lack of optimal composite material properties. The Taguchi method is a methodology in the field of engineering which is very much aimed at improving a product quality in a time process while at the same time reducing costs and minimal resources. The Taguchi method is a product or process that is robust against noise, therefore this method is a robust design. In writing this research, I have experience in the process of making and researching carbon in body organization in the Mechanical Engineering University of Jember named Tawang Alun, here I will conduct research in analyzing the optimal parameters for the surface roughness characteristics of front cover products made of carbon fiber using a vacuum process. resin infusion aid. The factor that contributes the most to the surface roughness response is vacuum pressure with a contribution of 25.20%. For hardener factor contribution of 14.93% and coating factor of 23.77%. The contribution error that occurs is 36.09%. Each factor has a value contribution that is not too different. Based on the data and analysis results that have been obtained using the Taguchi method with the help of Minitab 19 and Microsoft Excel, it shows that the parameter of vacuum pressure has a significant influence on the results of surface roughness. While the hardener parameter has no significant effect on surface roughness, then the coating parameter has a significant effect on surface roughness. In the calculation of the F test, it can be concluded that the optimal factor parameters in making a front top with a small surface roughness value are 0.4 bar vacuum pressure, 60% hardener and PVAC coating.
