Abstract

Anwarul Huda Islamic Boarding School is an educational institution located in Malang City, East Java with a total of 269 students. Based on the results of interviews with the management of the education division, Anwarul Huda Islamic Boarding School has problems in managing student data. The management of student data, such as the management of value data and attendance data is still done manually, so it is considered less effective and efficient. In the implementation of learning activities, students are also still often found cheating, namely there are still many students who commit attendance forgery. Based on these problems, the design of the user experience of the attendance application and the academic assessment of students was made. With this design, it is hoped that it can help the education division and the developer in creating a system that can help in managing student data. The method used in this study was to use user-centered design (UCD). The result of this study is a solution design in the form of a high-fidelity prototype which is then evaluated using usability testing. As for the results of the usability test, in the aspect of effectiveness, scores were obtained of 98.07% for admins, 98.33% for teachers, and 100% for students.

Abstract

Technological developments in the medical field have developed rapidly, one example is the manipulator robot. For example, in some cases there are people suffering from stroke who have difficulty moving their limbs. Due to the limited number of rehabilitators, the rehabilitation process took longer and they had to wait in line to carry out rehabilitation. The movement of the robotic manipulator's leg will be based on the movement of the human leg by reading electromyography (EMG) signals generated from the leg muscles through the electrodes. Then an exponential filter is used to reduce the noise from the EMG signal. After filtering the signal obtained will be classified using a decision tree classification. Then the AX-12A servo is used to move the legs of the manipulator robot which has 4 degrees of freedom. The results of the decision tree classification have amplitude values for each movement, which include 0V to 1.995V as a squatting movement with an angle of 450; 1.995V to 2.985V as a 90° seated motion; 2.985V to 5V as a standing movement with an angle of 1800. The test results obtained determine the movement of the leg robot has an accuracy of 70.667% for the total average accuracy. The subjects used were 10 with 5 movements at each angle.

Abstract

Every individual will not be spared from mental health problems. Therefore, proper handling must be done to prevent more severe problems from occurring. Counseling is one way to avoid these problems. The Faculty of Computer Science is one of the faculties at Brawijaya University with counseling guidance services currently under student services. However, over time there are problems with resources experienced by the counseling guidance service. So the counseling service coordinates with the faculty's student executive board to initiate peer counseling services to increase students' awareness of the importance of mental health and overcome the existing counselor resource problems. In its implementation, the registration, data collection, and reporting process is still carried out separately, which can confuse students using the service. The author offers a solution by utilizing the Flutter framework technology to develop a mobile information system that can help simplify the counseling guidance process. The research was conducted using the waterfall method, from the needs analysis stage to the conclusion. The implementation results in an information system that can handle the administrative process of counseling guidance services. The main features of this information system are counseling guidance scheduling, counselor scheduling, counseling history recording, and writing final counseling reports. Additional features, such as user profiles and notifications when certain activities occur, are also developed. The information system successfully obtained valid results for all test cases using the validity testing method. For usability testing, the system got an average score of 85,47 using the system usability scale method, which is included in the acceptable category on the acceptability range, level B on the grade scale, and excellent rating on the adjective rating. This score considerably increased from the previous system's score, namely 52,75.

Abstract

The availability of chicken meat is inversely proportional to the demand, resulting in meatball producers being unable to choose proper chicken meat. In making meatballs, quality meat is needed that is fresh, firm, and fit for consumption. Then a classification system was created that could detect quality of chicken meat based on the aroma and texture. System input values come from the MQ-135 gas sensor and resistance circuit (voltage divider). Input data is processed using the fuzzy - Mamdani method on Arduino Pro Mini. Processed data is displayed on the Oled ST7789 LCD and the buzzer sound indicator. The system is small in size with a voltage source from the battery, so the classification system is portable. The results of functional testing of the MQ-135 sensor in measuring ammonia gas levels affect the output voltage value by 96.78%. While the voltage range has a measurement of 96.29% with a measurement range of 1K-100KΩ. Broiler filet breast meat has an average resistance value of 26.32K - 33.92KΩ and an ammonia content of 5.41 - 7.41 ppm with wet-processed meat, while the average resistance value and ammonia content of dry processed meat is 27.02K - 34.52KΩ and 5.45 - 7.33 ppm. System accuracy in classifying using the fuzzy - Mamdani method has a proportion of 83.33% in 24 tests.

Abstract

User experience is all the effects felt by the user after the user interacts with the system, device, or product. User experience is one of the most important things to consider, both during the design and development process of a product. The goal is to find out how users feel, assess motivation and find out user expectations for the system. Intrinsic Motivation Inventory (IMI) is one of the methods used to measure the subjective experience of users who interact with the system. Evaluation in this method prioritizes the level of intrinsic user perceptions of the value/usefulness scale, interest/enjoyment, and the perception of user choice when interacting with the system. To follow up on these problems, researchers provide a design solution in the form of an IMI-based measuring instrument called IMITO. In designing IMITO, researchers chose the User Centered Design (UCD) method, because the method design process focuses on the user's needs and a more in-depth analysis of the target audience. Evaluation of design solutions in accordance with usability testing tested by 12 participants. The results of the usability test on the effectiveness aspect are 98%, the efficiency aspect is 13.44 goals/second and the satisfaction aspect is 75% which is included in grade B. Based on these three aspects, the final usability score is 90.02% which is included in the adjective rating category Excellent, grade A.
