Many accidents are caused by drowsy drivers. To prevent such accidents, it is necessary to create a device that can detect early drowsiness on the driver and immediately wake the driver. From the study it is known that a reliable indicator to measure drowsiness is the average duration of eyelid closure. This paper presents a prototype of drowsiness detection on the driver using a low-cost EMG, called Myoware, which can be used to detect the closure of the eyelid without injuring the eyes, by simply attaching it to the skin around the eyelid. To facilitate this attachment, an eyeglass is used. Furthermore, with the addition of ESP8266, it has been possible to create a drowsiness level detector that can be monitored online via the internet.

<span>This paper proposes an improved control and monitors between two different PLCs, the Mitsubishi, and Omron. The main advantage is interoperability and communication between both PLC. The use of NI OPC server as the software interface reached interoperability and communication. There were developed two field applications to test interoperability. Laboratory virtual instrument engineering workbench (LabVIEW) uses as the software application for creating the user interface to control and monitor. This improvement show OPC server technology solves data compatibility issue between different driver controller’s and reducing development cost. Regardless of whether there are more than two different PLCs, it's enough to use the NI OPC server. So the benefit of the NI OPC server is not limited to two types of PLC used right now but can also use the other manufacturers. Besides, the improvement of the previous study is the use of the LabVIEW makes data from the OPC server displayed more realistic. The use of LabVIEW allows additional monitoring functions, one of which is LabVIEW vision. Data utilization becomes more flexible, and so it can use for more complex purposes. It is envisaged that this is very useful for Integrator engineer to implement this method in industrial automation</span>

Vocational education provides necessary education and skills, which is directed at the mastery of certain expertise. As the learning outcome of this education, the graduates of Politeknik Mekatronika Sanata Dharma have been able to solve engineering problems in terms of maintenance and repair, operation, and assembly of industrial automation machines. For this reason, problem solving skills are important to learn. This paper presents a research on the effect of developing TRIZ-based competency test material on improving problem solving skills. The subjects of this study were 60 students of Politeknik Mekatronika Sanata Dharma. After several TRIZ-based competency tests, the results revealed that the problem solving skills of students on the basis of a systematic approach have increased, while problem solving on the basis of intuition (trial and error) have decreased.

Maintenance is an activity that helps to reduce risk, increase productivity, improve quality, and minimize production costs. The necessity for maintenance actions will increase efficiency and enhance the safety and quality of products and processes. On getting these conditions, it is necessary to implement a monitoring system used to observe machines' conditions from time to time, especially the machine parts that often experience problems. This paper presents a low-cost intelligent monitoring system using NodeMCU to continuously monitor machine conditions and provide warnings in the case of machine failure. Not only does it provide alerts, but this monitoring system also generates historical data on machine conditions to the Google Cloud (Google Sheet), includes which machines were down, downtime, issues occurred, repairs made, and technician handling. The results obtained are machine operators do not need to lose a relatively long time to call the technician. Likewise, the technicians assisted in carrying out machine maintenance activities and online reports so that errors that often occur due to human error do not happen again. The system succeeded in reducing the technician-calling time and maintenance workreporting time up to 50%. The availability of online and real-time maintenance historical data will support further maintenance strategy.

As one of vocational education in Indonesia, Politeknik Mekatronika Sanata Dharma must be able to produce graduates who are competent and skilled in the field of mechatronics. In order to achieve this, practical and workshop learning must be given a large portion. However, some practical tools available are limited, due to constraints in the cost of procuring equipment that is quite expensive. This paper presents an active learning through the practice of developing a simple industrial control simulation program, using Proteus and LabVIEW software. One example of the control simulation presented here is the control on the conveyor as a supplier of items. From the observation and learning evaluation, it was found that by making a simple simulation program, students more easily develop skills in mathematics, logical thinking and problem solving. The effectiveness of learning can be measured from the value of student satisfaction and involvement, which in the example here is quite high. Students were enthusiastic and involved, starting from the design of the conveyor simulation image, making the simulation circuit in Proteus, programming the microcontroller, and making the simulation program at LabVIEW, even to realizing it to the actual conveyor.
