Abstract

This The rapid growth of TikTok social media has made it an effective digital promotion medium for Micro, Small, and Medium Enterprises (MSME). —The large number of comments left by users serves as a valuable source of information to measure customer perception and satisfaction. However, the characteristics of social media text, which are unstructured, informal, and contain slang and emojis, make manual analysis difficult. This study aims to classify customer review sentiments regarding MSME food products on TikTok into positive, negative, and neutral categories using the Multinomial Naive Bayes algorithm. The dataset consists of 1,041 clean comment entries collected via web scraping. Text preprocessing steps include case folding, slang normalization, stopword removal, and the removal of empty and duplicate data. Sentiment labeling was conducted using a lexicon-based approach, while feature weighting was performed using Term Frequency-Inverse Document Frequency (TF-IDF). The dataset was split into an 80% training set (832 data points) and a 20% testing set (209 data points). The model performance evaluation showed that the Naive Bayes algorithm achieved an overall accuracy rate of 75.60%. The model demonstrated high performance on the neutral class with an F1-score of 0.85 and a precision of 1.00 for the positive class. This research provides a practical contribution for MSME owners in evaluating customer feedback and developing more responsive digital marketing strategies‖.

Abstract

The process of recording teacher attendance at SD Negeri 50 Kota Bengkulu still uses an attendance book, resulting in manual data management. This study aims to develop a web-based teacher attendance system using QR Code and location validation. Data were obtained through observation, interviews, and literature study. The system was developed using the Waterfall method with PHP and MySQL and Visual Studio Code. The admin can manage teacher data, schedules, QR Codes, attendance data, and reports, while teachers record their attendance by scanning the QR Code and logging in using a username and password. The system automatically displays the schedule and validates the attendance time and location based on a predetermined polygon area. The system also limits attendance recording to once per day and provides a 15-minute late tolerance. The implementation results show that the system can perform attendance recording, location and time validation, data storage, and report generation, which can be printed and exported to Excel. Testing using Black Box Testing shows that the main system functions operate according to the requirements. The developed system can assist the school in digitally recording and managing teacher attendance and provide data for administrative needs.

Abstract

The development of information technology has encouraged the implementation of digital attendance systems in various government institutions to improve the effectiveness of employee attendance data management. However, the attendance system used at Talang Perapat Village Office, West Seluma District, still has limitations in accurately validating employee attendance. This study aims to design and develop a web-based attendance application using the geolocation method at Talang Perapat Village Office, West Seluma District. The application is designed to support a more effective, accurate, and transparent attendance recording process through the utilization of geolocation technology and photo documentation as attendance validation. The methods used in this study include observation, interviews, and literature review, while the system development process applies the Waterfall method. The resulting system is capable of recording location-based attendance, capturing photos as proof of attendance, and monitoring attendance data in real time. The developed application has proven to enhance the validity of employee attendance data, prevent attendance fraud through location and photo verification, and accelerate the attendance report management process for administrators at the Talang Perapat Village Office, West Seluma District.

Abstract

Campus internet networks have an important role in supporting academic activities and digital services at Universitas Muhammadiyah Bengkulu. The increasing number of users and internet traffic has caused a decline in network quality, especially in Quality of Service (QoS) parameters such as Delay, Throughput, Packet loss, and Jitter. These conditions often occur during lecture hours, e-learning access, streaming activities, and other campus activities. This study aims to determine the performance condition of the campus network, model the network using Network Simulator-2 (NS-2), and analyze the effect of implementing network optimization scenarios on improving network performance. The research method uses network simulation with the NS-2 application on Linux Ubuntu through 20 simulation scenarios consisting of 10 scenarios before optimization and 10 scenarios after optimization. The optimization parameters applied include reducing backbone Delay from 10 ms to 1 ms, increasing queue buffer capacity from 50 to 200, implementing the RED queue method, configuring static nodes, and increasing the data rate to 54 Mbps. The results showed that the network condition before optimization had an average QoS index of 1.70 or 42.5% categorized as poor. The highest Delay reached 3103.48 ms, the lowest Throughput was 8.55%, the highest Packet loss reached 91.45%, and the highest Jitter reached 1619.48 ms. After optimization, the average QoS index increased to2.37 or 59.25% categorized as less satisfactory. The best Delay decreased to 6.05 ms, Throughput increased up to 100%, Packet loss decreased to 0%, and the best Jitter reached 3.01 ms. These results indicate that optimization using NS-2 is able to improve the quality of campus network services.

Abstract

Administrative services at the urban village level are public services that are directly related to community needs, such as applications for Business Certificates, Certificates of Indigency, Domicile Certificates, and Cover Letters. However, administrative services that are still carried out manually may cause several problems, including long queues, service delays, recording errors, and difficulties in monitoring submission status. This study aims to develop a mobile application for administrative services at Nusa Indah Urban Village using Kodular and TinyDB. The system development method used in this study is the Waterfall model, which consists of requirement analysis, system design, implementation, testing, and evaluation stages. The application was developed as an Android-based application with main features including user authentication, service dashboard, user profile, letter submission, supporting documents, submission data management, local data storage, service status, letter documents, and user guidance. TinyDB was used as a local data storage medium to store login data, user profiles, letter submission data, submission history, supporting documents, and service status. The application was tested using the black-box testing method to determine the suitability of application functions based on the given inputs and generated outputs. The results showed that the application ran according to the design, and all main features tested could be used properly. This application was able to support the process of letter submission, applicant data storage, service status monitoring, and letter document generation in a more practical and organized manner. Therefore, the developed application can serve as an initial prototype to support digital-based urban village administrative services.
