2024-06-03T16:02:11+07:00

Muhammadiyah Gresik University is one of the educational institutions in Gresik City. At Muhammadiyah University of Gresik there are various faculties and study programs which are certainly not far from the student attendance registration system. Muhammadiyuah Gresik University uses an attendance registration system in the form of Manual Attendance and SPADA Digital Attendance. From this attendance system, fraud often occurs. Apart from these things, the Administration of the Faculty of Engineering also has several obstacles in managing student attendance data, namely that there are two types of attendance list management so that student attendance data must be managed twice through Manual attendance and SPADA Digital Attendance. And in both systems the number of attendance is not listed, so you have to calculate attendance manually. To overcome this, an attendance system update was carried out, namely using IoT-based Fingerprint using an ESP32 microcontroller. The work process in this attendance system is that the attendance system can be monitored in real-time and record student attendance efficiently. This system is processed by an ESP32 microcontroller which then manages the data using Google Spreadsheet in real-time. The results of implementing this system can be real-time monitoring of attendance, effective data management, and reducing the occurrence of fraud in student attendance.

Implementation Of Hector Slam Algorithm For Indoor Mapping Using Automated Guided Vehicle Robot

2024-05-03T12:41:09+07:00

Developments in the industrial world are increasingly rapid along with technological developments,
autonomous robots are one of the many developed and used in the industrial world and become important
which is widely used in various industrial sectors. Autonomous robots move using navigation systems to
recognize the environment, navigation has an important role in autonomous robots but navigation requires an
accurate map with the surrounding environment so that the robot can move in accordance with the
environment. In this study, mapping accuracy analysis was carried out using the Hector-SLAM algorithm
method to map the surrounding environment by simulation and real-time (robot). This research has several
important compounds including robot operating systems (Robot Operating System), data filters such as hector
scan matching where to construct the data obtained, the type of sensor is very influential on the quality of the
map produced. This study tests whether the hector scan matching algorithm can do environment mapping
accurately. The results of this study can be concluded that, the map produced from the simulation and robot
(real) has a fairly good accuracy, this is based on matching the results of the simulation mapping and robot
(real) which has an accuracy of SSIM: 77.26%, MSE Error: 3.96%, Pixel Match: 55.46% of the robot mapping
results (real) while from the simulation results are displayed in the 2nd scenario used to compare with robots
obtained accuracy of SSIM: 87.29%, MSE Error: 1.65% and Pixel Match: 81.11%.

Utilisation of A Star Algorithm in Determining Tourism Routes in Palangka Raya City

2024-06-03T16:02:11+07:00

The Utilization of the A* Algorithm in Determining Tour Routes in Palangka Raya City is a study aimed at providing a solution for determining optimal tourist routes for visitors in Palangka Raya City. By employing the A* algorithm, this research offers an efficient tool to find the shortest route between selected tourist destinations, considering both distance and travel cost. The method involves initializing a graph that represents the relationships between tourist destinations, followed by the implementation of the A* algorithm for finding the best route. The research findings demonstrate that this algorithm can provide optimal routes with accurate estimations of distance and cost. A brief discussion on the research results highlights the strengths and limitations of this algorithm in the context of tourism applications. In conclusion, this research makes a significant contribution to facilitating visitors in planning their tourist trips in Palangka Raya City, with the potential positive impact on the tourism industry and visitor experiences.

Prototype of Data Record System for RFID-Based Measuring Instruments, Measures, Weights and Equipment

2024-06-03T16:02:11+07:00

At present, the inventory and identification of Measurements, Measures, Scales, and Equipment (UTTP) in legal metrology activities still uses conventional methods, namely using register books and certificate archives. To increase work effectiveness and efficiency, this study designed a prototype of a UTTP data recording system based on Radio Frequency Identification (RFID) as an alternative to using RFID technology to replace conventional systems in terms of recording and storing test result data. This study used quantitative methods. The data obtained will be processed and analyzed so that a conclusion is drawn. The data from this prototype reading can be converted to Microsoft Excel in the form of a UTTP data set file which is useful for metrological supervision and recording of State Property (BMN) in the laboratory. For the prototype performance test designed, several tests were carried out, including system function testing, tag detection distance testing, testing with barrier media, reader reading angle testing, tag detection average time testing. Based on the test result data, the prototype designed has served to identify UTTP. The maximum RFID tag detection distance is 2.5 cm for card type, 1 cm for sticker and key type. The read time interval of each tag is less than 1 second. Reader readout is optimal at an angle of 45º-90º. Testing also proved the effect of reader barrier material on tag readability.
