Abstract

Internship is an activity organized by vocational schools to improve a particular field of expertise and prepare students to enter the world of work. PKL activities at SMK Negeri 1 Sumenep have three stages, namely planning/data collection, implementation, and assessment. The data collection stage to the assessment stage is still done manually which results in frequent gaps in data processing for street vendors. Therefore, at SMK Negeri 1 Sumenep need an information system for the management of street vendors activities. Before developing an information system, a user interface design is needed as a basic material or reference in system development. User interface design focuses on the appearance of a product and usability to increase the level of ease of display. One approach in designing user interfaces is Human Centered Design (HCD) which involves users in the process. The resulting user interface design is a display on the role of admin, street vendors committee, supervising teachers, and students. Usability evaluation uses the heuristic evaluation (HE) method which involves experts during the evaluation and by following usability principles. The results of usability testing on the user interface found a total of 11 problems from the evaluator.

Abstract

Corona Virus Disease is a new outbreak that can transmit infection through close contact or water droplets. Corona virus attacks the human respiratory system so that it can cause illness with symptoms of fever, cough and shortness of breath that can cause death. The use of a mask that covers the nose and mouth can prevent transmission. As a form of prevention, people are starting to be forced by regulations to always use masks in public places and when interacting with other people. However, it will be difficult for the authorities to monitor large groups of people. These problems can be solved with a system to detect masks. Mask detection in this study uses the naive bayes classification to distinguish a face with a mask correctly or incorrectly and also without a mask. The information used for classification is obtained through the histogram of facial image texture feature extraction using Local Ternary Pattern. The extracted image is preprocessed which includes resizing the image width and image grayscaling. The data used are 3,900 face images. Tests were carried out on the size of the image width, the threshold value, the number of bins, and the split of training and testing data. The results of the naive bayes classification produce an optimal accuracy of 68.462% with an image width of 50, a threshold value of 4, the number of bins 32, the distribution of training and testing data are 70%: 30%. Tests with 2 classes, namely correctly masked faces and unmasked faces, obtained an accuracy value of 86.15%. Based on these results, it is known that the naive bayes classification cannot properly classify images in the masked class incorrectly.

Abstract

Maintaining security and the environment is a shared responsibility as citizens. One of the most important parts in maintaining security and the environment is the participation of the community. In this case the form of community participation to protect the environment is manifested in the form of a security and environmental system, one of the community's efforts to maintain security and the surrounding environment is to carry out patrols or siskamling activities. Meanwhile, the rapid development of technology forces us to keep up with these technological developments, especially in the world of information and communication technology. Technology plays an important role in the modern era as it is today, one of the technologies currently developing is Augmented Reality (AR). AR is a technology that combines virtual objects both 2D and 3D into a real environment and then projects these virtual objects in real time. Utilization of AR is done by implementing it on a system with the aim of combining virtual objects with real objects. Based on an interview with the security chief in question, it was not easy for officers to coordinate with each other with the Handy Talky (HT) communication tool, the coordination between officers was quite complicated because other officers and the field coordinator could not visually blend in with only the HT. Given these problems, this research implements Augmented Reality Location Based using the Navigation Coordinate System which is a coordinate system mapped from GPS points which will then become the coordinate points on the smartphone screen camera display. By implementing this Location Based Augmented Reality in an application with the Android platform, the Security and Security Service officers can visually unite other officers on their smartphone screens. In this study, usability testing was also carried out using the System Usability Scale method, with an average result of 77.25 which can show Augmented Reality applications that are easy to use by Security and Security Officers.

Abstract

The isolation room in the hospital has very strict safety and health procedures to maintain the sterility of the area. This requires health workers to use personal protective equipment (PPE) during their activities in the isolation room. The virus outbreak in 2020 made hospitals need more isolation rooms, resulting in higher demand for PPE supplies and a higher risk of health workers being exposed to the virus. For this, an autonomous mobile robot system is needed at the hospital to help the workforce, especially in terms of logistics. The system consists of several components including Kinect sensor, encoder, IMU, and with Robot Operating System (ROS) middleware. The advantage of this research is the shape of the robot prototype which has a large size. To create autonomous navigation, a path planning method is needed, therefore the Timed Elastic Band (TEB) algorithm is used. Before navigating, a precise map is needed, therefore a map-making method using the GMapping algorithm is needed. The test results on navigation show an accuracy of 50% from 10 trials that have been successful 5 times. Navigation is carried out using the TEB algorithm computation time of 2.77 seconds and the average time of successful robot movement to the destination coordinates is 129.98 seconds. For mapping, the accuracy is 50% with map size accuracy of 98.84%.

Abstract

Cooking oil is one of the basic needs of the Indonesian people for food processing ingredients, especially for frying process. Palm cooking oil is commonly used by Indonesian people because it matches the Indonesian people's taste. In its use, cooking oil is often used repeatedly for savings which is known as used cooking oil. The use of used cooking oil can increase the risk of several diseases for the body, such as carcinoma and diarrhea caused by the accumulation of peroxide values, as well as changes in the color and clarity of the oil. To determine the quality of the oil, the method used today is to test the peroxide number in the laboratory. However, this method takes more time and is not cheap. So that a system was created that can detect the quality of cooking oil based on color and clarity using the Naive Bayes method to shorten the time at a lower price. This study uses a TCS3200 sensor to detect color changes, and an LDR sensor to detect oil clarity. There are 2 classes used, namely the Eligible class to declare that the oil is still suitable for use and the Inappropriate class to declare that the oil is not suitable for use. In the research results, the accuracy of the TCS3200 sensor is 95.15%, the accuracy of the Naive Bayes method is 87,5%, and the overall system accuracy is 87.5%.
