Abstract

Islamic Civilization History learning at MAN 1 Medan still relies largely on conventional media, while students' Android smartphones have not been optimally directed toward learning activities. This study aims to design and develop an Android-based learning information system that integrates Islamic Civilization History content, digital literacy, and religious moderation. The study applies a Research and Development approach with Rapid Application Development for software construction. User requirements were identified through observation, interviews, questionnaires, and literature review. The application was developed using Kodular with Airtable as the database. It enables teachers to manage learning materials, videos, quizzes, and scores, while students can access materials, videos, quizzes, and learning results. Functional evaluation through black-box testing covered 12 scenarios across teacher login, learning materials, videos, quizzes, account registration, and student login modules. All scenarios were valid, resulting in a 100% functional success rate. These findings indicate that the prototype satisfies the designed core functional requirements. Nevertheless, its effectiveness in improving digital literacy and religious moderation cannot yet be established because the source manuscript does not report UAT results or experimental testing with students.

Abstract

SMAS Darussalam Medan is a private high school located at Jl. Darussalam No.26, Sei Sikambing D, Kec. Medan Petisah, Kota Medan, North Sumatra 20119. The student attendance process is still carried out by recording attendance in an attendance book and compiling the attendance data, which has led to several issues, particularly in terms of monitoring attendance by parents. There are still some students who skip school. If parents/guardians want to obtain information about student attendance, they must come directly to the school and check the attendance book and search for attendance data one by one, which requires a lot of time, energy, and money. The purpose of this research is to develop an Android-based information system that can be used for student attendance using location-based services and mock location detection. This feature functions to obtain the student's current location when taking attendance and prevent students from cheating by using the Fake GPS (false location) application. The information system was built using the Kodular framework and Airtable database. The system development method used was the waterfall method. With this information system, it is hoped that parents/guardians can obtain accurate student attendance information via their Android smartphones.

Abstract

 Stress is a condition commonly experienced by university students due to academic demands, lifestyle, and daily activities. Poorly managed stress can negatively affect students’ physical and psychological well-being. This study aims to develop a web-based expert system to assist in the early detection of students’ stress levels using the Certainty Factor method. The symptom data were compiled based on Hans Selye’s stress theory under expert guidance, while the expert Certainty Factor values for each symptom were obtained through consultation with a psychologist. The system was developed using PHP programming language and MySQL database. The detection process is performed by processing the users’ confidence levels toward the symptoms along with the expert confidence values using the Certainty Factor method to determine three stress categories: mild, moderate, and severe. The calculation simulation resulted in Certainty Factor values of 0.50 for mild stress, 0.52 for moderate stress, and 0.18 for severe stress, resulting in a moderate stress detection. Black-box testing was conducted using 19 scenarios covering the functions of the user and admin pages, and all scenarios were successfully executed as expected, resulting in a 100% success rate. The system also provides recommendations related to lifestyle based on the detection results. Based on these results, the system can be used as a supporting tool to assist university students in conducting early stress detection independently.

Abstract

The rapid growth of social media has driven a surge in public opinion across digital platforms, including YouTube. The transportation electrification policy, particularly the adoption of electric bicycles in Indonesia, has elicited a wide range of public responses. This study aims to build a web-based sentiment analysis system that classifies YouTube comments related to this policy using the BERT (Bidirectional Encoder Representations from Transformers) algorithm. The system was developed using the waterfall model and covers text preprocessing (text cleaning, case folding, normalization, and tokenization), sentiment classification into positive, neutral, and negative categories, and interactive visualization of the results. The dataset consists of 1,000 comments from 8 YouTube videos collected through web scraping period of 2022, 2023 and 2024. The BERT model achieved an accuracy of 91.50%, with a macro precision of 88.34%, a macro recall of 90.80%, and a macro F1-Score of 89.55%. The classified sentiment distribution comprises 201 positive comments (20.1%), 645 neutral comments (64.5%), and 154 negative comments (15.4%). The web-based system integrates the entire workflow, from dataset upload and preprocessing to sentiment analysis and visualization, and can therefore support data-driven decision-making for policymakers.

Abstract

The management of incoming and outgoing mail archives at Madrasah Tsanawiyah Baiturrohim Blimbing is currently carried out manually using physical ledgers and paper-based storage systems. This conventional method results in several administrative problems, including difficulties in searching and retrieving documents, inconsistent letter numbering, delays in the disposition process, risk of document loss or physical damage, and inefficiency in terms of time and human resources. This study aims to design and develop a web-based information system for managing incoming and outgoing mail archives by applying the Sequential Search algorithm as the main search mechanism. The research uses a qualitative descriptive approach with data collected through observation, interviews, and literature review. The system is developed using the Prototype method through iterative stages: requirement analysis, prototype design and development, and system testing and evaluation. The system is implemented using PHP, SQLite, and Bootstrap. Testing of four algorithm scenarios confirms theoretical time complexity: O(1) in best case (1 iteration), O(n) in average case (5 iterations, T(9)=(9+1)/2=5), worst case (9 iterations), and not found case (9 iterations). Black Box Testing across 8 scenarios shows a 100% success rate. The developed system successfully improves the efficiency and accuracy of mail archive management, reduces manual recording errors, and facilitates timely administrative reporting.

Abstract

Apis cerana honey bee cultivation in Indonesia faces a major constraint of limited access to expert apiculturists for fast and accurate colony condition diagnosis. The manual and subjective diagnostic process creates uncertainty because one symptom can indicate multiple possible conditions. This research aims to develop a web-based expert system using the Certainty Factor (CF) method to diagnose Apis cerana honey bee colony conditions. The research methodology follows the Expert System Development Life Cycle (ESDLC) consisting of four stages: intelligence, design, selection, and implementation. The resulting knowledge base consists of 15 symptoms, 5 colony conditions, 5 IF-THEN rules, and a CF value matrix. The results show that the developed expert system achieved 100% accuracy when tested on 20 colony samples compared to expert diagnosis. All system functions performed according to specifications based on black box testing of nine scenarios. The system displays diagnostic ranking with confidence levels in percentages and provides a CF Combine calculation detail feature for diagnostic process transparency. Expert validation results state that the system is feasible for use as a diagnostic tool. This system provides a practical solution for farmers in various locations to diagnose colony conditions independently, quickly, and in a standardized manner.
