The fence is one of the leading security in maintaining a building. Conventional fence require operator to open and close it, so it does not effective and efficient. This problem can be solved with automated systems. This research aims to design fance system using finger print sensor based microcontroller arduino, which is equipped with a locking system that use a solenoid. This experimental research is starts from the design, fabrication and testing. Fences made have specifications 3.2 m x 1.5 m with a total weight is 30.67 kg, path lengthis 2.1 m, diameter sprocket 0.03 m, Voltage DC motor is 12 V and rotation is 195 rpm. The test results showed a good performance conform with its initial design, where a fence can be opened with a fingerprint has been recorded before. Solenoid can open and lock, likewise with the the photodiode can detect object is on the track. The test results obtained there are differences when opening / closing compared with the results design is 20%, with an average voltage is 12.06 V, current is 1 A, rotation is 135 rpm, and the time it takes 9.9 s, where the torque produced is of 0.64 Nm and maximum load can be driven by a DC motor is at 59.97 kg.

Heat and hold method is a method with temperature containment techniques in accordance with desired temperature and time functions. This technique aims in adjusting the characteristics of microbial resistance to temperature and saving energy consumption. In this study, a tank with temperature control system was designed for heat and hold the temperature according to the system requirements. Control of the temperature in the heating tank can be done based on the Arduino microcontroller. Arduino reads data from the temperature sensor and activate the heater according to temperature set on the Arduino. Arduino Ethernet Shield acts as Arduino data communication with a database connected to the internet network. The results of this study are in the form of a prototype that shows an IoT-based temperature monitoring tool that can be accessed anywhere via Web-based monitoring system interface. The test was carried out in 2 stages, namely testing by determining target of heater and testing with Holding and Heating with a delay of 10 minutes and 20 minutes. The heating tank temperature control system maintain a temperature of 40oC, 50oC, 60oC for 10 minutes. The temperature holding condition at a certain time is called holding. Henceforth the system temperature is at 70oC.

The Covid-19 pandemic is a disaster for all of us, Vocational Education is also affected by the Covid-19 pandemic which forces online lectures, one of which is at the Industrial Chemical Technology Polytechnic (PTKI), in the implementation of the exam at PTKI Medan carried out collectively with questions exam in the form of an essay. There have been many studies on online essay exams but the scope of the discussion is for automatic correction or similarity based on text input. In vocational education, especially PTKI Medan, which has a test that is not limited to text input but there are calculations. Another weakness of text input is that the answers can be more easily copied and pasted by students. This research was carried out for 1 year starting from Odd semester 2020 to Even 2020. The method in developing information systems uses the waterfall model with the stages of needs analysis, system design, coding, implementation and the last stage of system maintenance. From the results of the research in the odd semester of 2020, the researchers used a text-based online essay exam model, but many weaknesses were found, one of which was the ease of students in using answers from the internet which were directly entered into the answer column. At the maintenance stage, the researcher updates the system by changing the image-based exam model, so students must write their answers on paper and then upload the answers to the website. The file upload system can overload the server if it is not controlled, one of the techniques used is to compress image files uploaded by students to the system and the maximum size can be compressed up to 78.48% from 1329 Kb to 286 Kb for this type. png data. In addition, to make it easier for lecturers to check answers, use the ezoom.js feature as a means to view answers in the form of images that are useful for zooming in, zooming out, rotating the answer images. Ezoom.js is a javascript that can be installed on php-based websites

Digital technology continues to develop until now such as in Industry 4.0. In the industry, many still use conventional systems such as Induction Motor Starters using the Direct on Line (DOL) System. This study aims to build a system to be able to upgrade conventional systems to digital-based systems. The method used is testing by making a design and then comparing the data obtained to see the response time. From the results of the study, the system can work well. Both testing on conventional systems and online systems. In conventional systems, the system works faster with an average response time of less than 1 second, while with an online system, the response depends on the internet network used so that an average of 1.6 seconds is obtained. In addition, the results of testing using internet of things software show that the system is integrated between conventional systems and digital systems where when the induction motor is ON, a current reading of around 60A will be obtained on the IoT software display and when the motor is OFF, the current reading will drop to close to 0 Ampere.
