Abstract

Academic activities are daily operational activities that occur in an educational institution, especially in universities. Academic activities must be carried out by students and lecturers. Within the scope of academic activities at the Faculty of Engineering, University of Muhammadiyah Bengkulu, the media used to convey information on the current academic schedule no longer uses bulletin boards but uses social media, namely whatsapp. Although academic activities are routine, it is still common for students and lecturers to forget the schedule of academic activities. To overcome this, the Faculty of Engineering requires a personal digital assistant application (virtual assistant) as an accurate, efficient and portable reminder. The virtual assistant application that is built consists of two platforms. First, the mobile platform used by lecturers and students to view some academic agenda information and receive real-time information/announcements and notifications/alarms related to academic activities. Second, the web platform used by the Administration to broadcast announcements or invitations to mobile application users. Based on the test results, the virtual assistant application can run on two platforms.

Abstract

The development of technology is currently growing very rapidly which allows us to access various kinds of data and information, but there are lots of people who abuse this ability, for example phishing activities that often target data and information owned by individuals and companies. Loss of data and information is very detrimental to individuals and companies, where the data and information can be used as a tool for extortion, used as a fraud tool and even the information can be traded. The main reason for the importance of maintaining the security of information is to protect information from online crimes. One of the techniques designed to protect important and confidential information is a cryptographic technique using the Blowfish algorithm and also a QR Code which functions as second line security. where data and information that has been converted into a QR Code cannot be changed. The purpose of this study is to apply the Blowfish Algorithm for Encryption and Decryption of the QR Code into an android-based application system. The results of this study are: The blowfish algorithm can be implemented into an android-based application. Plaintext which is converted into ciphertext using the blowfish algorithm can be used as a QR Code using a QR Code generator. A QR code is up to 7089 numeric digits and 4296 alphanumeric characters. The amount of information will affect the QR Code module, so the symbols in the QR Code will become more complicated. This application has received an assessment from respondents from users with an average value (6.5) with the category of choice "agree".

Abstract

This study is entitled the implementation of the a* (a-star) algorithm for website-based search of tourism sites in the city of Bengkulu. The main problem ishow to build an information system search for the nearest tourism location in the city of Bengkulu. Information Systems search for this tourism locationusing the a* (a-star) algorithm method and this information system also displays information about existing tours. The a* (a-star) algorithm method was chosen because this method determines the shortest path between the starting and ending points of an existing tour. Based on the results of the discussionThe A-star algorithm is considered more effective in finding the shortest route. This is proven by testing the shortest route randomly and thoroughly 15 times for all tourist destinations. The results show that the routes generated on average are more effective and shorter than the routes generated on Google Maps.

Abstract

Many web-based applications/forms serve as online data entry devices equipped with facilities for uploading image data. When uploading image data, the image file is often incompatible or cannot be uploaded because the size is too large. Users have to resize those files separately. For example, with several compression applications used such as photoshop, gimp, photoscape, photo compressor, image size and many other compression applications. Web-based applications should be able to automatically resize the file according to the appropriate file size so that it can save time and speed up the process. To deal with the problem of automatic compression, the user must provide or build a web-based application that can directly compress files on the web because automatic file or image compression is available on the website without compressing them separately beforehand. With this automatic compression form application, it certainly reduces costs. (quota) internet, shortening time and also making it easier for users or users when uploading files on the web. The algorithm that is suitable for resizing files in online web applications is the hufman algorithm.

Abstract

Based on data from the PP Muhammadiyah Research and Development Council, there are 62 Muhammadiyah Universities spread throughout Indonesia. Of the many Muhammadiyah Universities it would be very easy if there was a system that could display information and the location of the university in the form of a map. GIS is a computer information system used to process georeferenced spatial data (in the form of details, facts, conditions, etc.) stored in a database. By implementing the Muhammadiyah University Geographic Information System, it is hoped that it can help users in obtaining spatial and non-spatial information about Muhammadiyah University which is spread throughout Indonesia. The system must consist of input and output, therefore the application built consists of an admin section as input and a user as output. The admin application is used to process Muhammadiyah University location data which was built using the PHP programming language and MySQL database. The user application is used for implementing GIS on mapping Muhammadiyah University in Indonesia which runs on the Android operating system and is built using Android Studio with the Java and XML programming languages. The application can display a list of Muhammadiyah University locations in Indonesia in the form of a map and an ordered list. Utilization of google map in the application is to display a map which uses the google map api and displays the route from the user's location to the selected university.

Abstract

The election of the chairman and deputy chairman of the OSIS is held every year by all schools including SMPN 10 Bengkulu Selatan. The election was carried out conventionally where this activity required quite a lot of money and energy as well as quite long teaching and learning hours which were cut to carry out the election of the OSIS chairman. Apart from that, there is the potential for fraud, human error, operational inefficiencies from the start to the end of the election, and non-real-time monitoring which are shortcomings of conventional voting systems. To answer this problem, research is proposed which aims to build a web-based e-voting system for the election of OSIS chairman at SMPN 10 Bengkulu Selatan. The software development method used is Rapid Application Development (RAD). The method emphasizes rapid and incremental prototyping.

Abstract

The high rate of theft of two-wheeled vehicles makes vehicle owners afraid to leave their vehicles. Most vehicle owners increase the security of their vehicles by providing a padlock key that is placed on the motorcycle disc.Along with the increasing acts of motorcycle theft, vehicle security must also be improved, so that vehicle owners are not afraid if they have to leave their vehicle. Therefore the author wants to create a security system by utilizing a smartphone as a vehicle control tool remotely. In this study a vehicle security system was designed with fingerprints as keys and realtime monitoring of vehicles via telegram by utilizing Arduino Uno, Relay, FingerPrint Sensor, ESP32 CAM and NodeMCU. This study used an experimental method which directly tested the vehicle. The test was carried out with 10 different fingerprints, 8 finger positions and 5 fingerprint obstacles. The test results show that the system can execute commands with an average delay time of 9.11 seconds and can provide notifications in the form of messages to Telegram and can be monitored in real time when someone tries to activate the vehicle.

Abstract

The increasing use of social media as a public space has encouraged the emergence of various opinions on government policies, including the Free Nutritious Food Program which is widely discussed on Platform X (Twitter). However, unstructured text data and diverse user perspectives pose challenges in accurately identifying sentiment. This study aims to analyze public sentiment using the Support Vector Machine (SVM) method with Term Frequency – Inverse Document Frequency (TF-IDF) weighting. Data were collected through web scraping from August to November 2025 totaling 4,002 tweets, which were then processed through labeling and preprocessing to obtain 3,129 data. Testing was carried out with three classification scenarios, namely three classes, two classes, and positive and non-positive. The results show that the highest accuracy obtained in the positive vs. non-positive scenario is 90.57%, followed by two classes at 90.34%, and three classes at 80.67%. These findings indicate that simplifying the number of classes can improve model performance. The SVM method with TF-IDF has proven effective in sentiment analysis on social media data.
