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.

Muhamad Khosyi Izzatullah — Tue, 30 Apr 2024 23:50:17 +0700

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%.

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

Ardelia Ruciragati Kumala — Wed, 29 May 2024 08:16:02 +0700

In metrological supervision, the method of recording data on Measuring Instruments, Measures, Scales, and Equipment (UTTP) still uses conventional methods by writing or typing data on surveillance forms. Generally, retrieving data for one UTTP takes about 2 minutes at the earliest. This time is only for data recording and does not include the allocation of time for technical testing so that it becomes an obstacle if the number of supervised UTTPs amounts to hundreds or thousands. To reduce the duration of data recording, in this study a prototype design of a UTTP data recording system based on Radio Frequency Identification (RFID) was carried out. The data communication system on the proposed prototype uses an On-The-Go (OTG) connection between the smartphone and Arduino UNO. This allows MFRC522 RFID modules connected to Arduino to access RFID data without the need for an external power supply and access to the network. The prototype features data storage on smartphone memory in Microsoft Excel format. Testing on the designed prototype includes data access to RFID tags in the form of cards, keys, and stickers. Based on the test, the maximum time required for the process of reading and writing data on RFID tags is 0.56 seconds, shorter than the conventional method which requires 124.56 seconds. RFID systems can detect tags up to a maximum angular tilt of 135º and can still function with barrier media in the form of plastic, wood, and cardboard.

Studi Performansi Algoritma Perencanaan Jalur Berbasis Informed Rapidly-exploring Random Tree Star

Tri Rahajoeningroem, Dwi Anie Gunastuti — Fri, 19 Jul 2024 09:09:35 +0700

Path planning is an important aspect in robotics, allowing a robot to reach its destination safely and efficiently. The Informed Rapidly-exploring Random Tree Star (Informed RRT*) algorithm has become one of the popular path planning methods due to its efficiency and ability to handle complex workspaces. Since its introduction in 2014, various variants of Informed RRT have been developed to improve its performance. However, there has been no comprehensive study comparing the performance of these variants. This research aims to conduct a comparative study of the performance of several Informed RRT variants in solving path planning problems. The algorithms compared are APF-IRRT, BI-RRT, Informed RRT* + DWA, Informed RRT*-Connect, Informed RRT*-PSO, MI-RRT-Connect, and Informed RRT* with wrapping** procedure. Algorithm performance is evaluated based on computation time and path length metrics. Experiments were conducted on various path planning scenarios with different complexities. The results show that certain Informed RRT variants perform better than others in different metrics. APF-IRRT and Informed RRT-Connect* generally have faster computation time, Informed RRT-PSO* and Informed RRT with wrapping procedure produce smoother paths. This research provides a better understanding of the strengths and weaknesses of Informed RRT variants, enabling the selection of appropriate algorithms for specific path planning applications.
