Abstract

Thesis title screening is crucial to prevent duplication of scientific work in the Faculty of Engineering, Universitas Muhammadiyah Bengkulu.2 This study examines the optimization of the similarity threshold for Jaro-Winkler and Levenshtein Distance algorithms using 50 dummy thesis title pairs.3 Binary evaluation shows that the Jaro-Winkler algorithm achieves optimal performance with an F1-score of 1.000 at a 0.85 threshold.3 Meanwhile, Levenshtein Distance achieves its optimal performance at a 0.70 threshold with an F1-score of 0.837.3 The Wilcoxon Signed-Rank test confirms a statistically significant difference in performance between the two algorithms with . The title screening system is recommended to implement the Jaro-Winkler algorithm.3

Abstract

Correspondence administration plays an essential role in supporting academic and administrative activities at the Faculty of Engineering, Muhammadiyah University of Bengkulu. However, the current manual process of managing correspondence often leads to several challenges, including slow administrative services, difficulties in tracking the status of letters, the risk of document loss, and inefficient archive retrieval. Therefore, a web-based system is needed to improve the effectiveness and efficiency of correspondence management. This study aims to design and develop a web-based correspondence administration application to manage incoming letters, outgoing letters, and official certificates in an integrated system. The system was developed using the Waterfall method, which includes requirements analysis, system design, implementation, testing, and maintenance. The design stage employed Context Diagrams, Data Flow Diagrams (DFD), Entity Relationship Diagrams (ERD), and user interface design. The application was implemented using the CodeIgniter framework with MySQL as the database management system. Black Box Testing was conducted to ensure that all system features functioned properly. The results show that the developed application improves the efficiency of administrative processes by accelerating correspondence services, simplifying document management and archive retrieval, reducing errors in document handling, and making it easier to monitor the status of letters. Overall, the system supports a more organized, effective, and efficient administrative process at the Faculty of Engineering, Muhammadiyah University of Bengkulu.

Abstract

Waste management is one of the issues that requires attention as community activities and the volume of waste generated continue to increase. Waste management that is still carried out manually can cause delays in identifying the condition of the trash bin, waste accumulation, and decreased environmental cleanliness. Therefore, a system is needed to assist in monitoring and managing trash bins automatically. This study aims to design and develop a Smart Trash Bin with a capacity indicator based on Arduino and an ultrasonic sensor that can detect objects and provide an automatic response. The research method consists of identification, literature review, analysis, and design stages. The system is designed using Arduino Uno as the microcontroller, an HC-SR04 ultrasonic sensor to detect objects and measure the height of waste, a servo motor to operate the trash bin lid, and a DFPlayer Mini with a speaker as a voice notification medium. The system operates when the ultrasonic sensor detects an object within a certain distance. The data obtained from the sensor are then processed by the Arduino Uno to control the servo motor, allowing the trash bin lid to open automatically. When the object is no longer detected, the lid closes again, and the system provides a voice notification through the DFPlayer Mini and speaker. The results of the study show that a Smart Trash Bin prototype based on Arduino Uno and an ultrasonic sensor has been successfully designed to open and close the trash bin automatically and provide a voice response. The designed system can help reduce direct contact between users and the trash bin, facilitate the waste disposal process, and support monitoring of the trash bin condition. Therefore, the Smart Trash Bin design is expected to improve the effectiveness of waste management and support the creation of a cleaner, healthier, and more organized environment.

Abstract

The development of Internet of Things (IoT) technology has encouraged the implementation of precision agriculture through plant monitoring and irrigation automation systems. This study aims to design and implement an ESP32 microcontroller-based automatic plant irrigation system integrated with the Blynk application for remote monitoring and control. The system uses a soil moisture sensor as the main parameter for irrigation decision making, as well as temperature and humidity sensors as supporting parameters to represent environmental conditions. The research method used is the Prototype model, which includes requirements gathering, design, prototype development, evaluation, design refinement, and coding. The implementation results show that the system is capable of reading sensor data in real-time, displaying information on the LCD and application, and activating the water pump via a relay based on the soil moisture threshold value. Testing shows that the pump is active when soil moisture is below 40% RH and inactive when it reaches ≥60% RH, and the system successfully connects to the WiFi network and application server with an average initialization time of 3–5 seconds. Overall, the system works stably, responsively, and effectively maintains soil moisture within the optimal range, thereby improving water use efficiency and facilitating continuous monitoring of plant conditions.
