Abstract

Aquaculture pond water commonly supports multiple aquatic species, including seabass and vannamei shrimp. This study specifically concentrates on vannamei shrimp cultivation in pond systems. Feeding management in shrimp aquaculture constitutes a critical operational parameter, as appropriate feed allocation directly influences growth performance, feed conversion efficiency, and overall production yield. This research involved the design and development of an automatic shrimp feeding system utilizing an HX711 load cell weight sensor integrated with a microcontroller-based control unit. Experimental evaluation demonstrated that the Real-Time Clock (RTC) module exhibited a time deviation of approximately one minute slower than the reference time recorded on a laptop. The implementation of the HX711 load cell sensor in the feed container yielded an average measurement error of 3.1% based on a 350-gram calibration test. The system was capable of dispensing feed with a minimum output resolution of 1 gram. Furthermore, operational data generated by the system are transmitted to a database, visualized through a web-based interface, and accessible for real-time monitoring.

Abstract

Water is an essential resource that sustains human life, particularly in fulfilling daily domestic needs. However, the availability of clean water in various regions around the world has been declining significantly, which is not proportional to the continuously increasing population growth. This condition necessitates efforts in managing and utilizing water resources efficiently and sustainably. One applicable approach is optimizing water usage in storage tanks through an integrated monitoring and control system. This study aims to design and implement an Android-based monitoring and control system for water usage that is capable of providing real-time information to users. The system is developed by utilizing microcontroller technology and mobile platforms to enhance the effectiveness of water management. The components used in the system development include an Android smartphone as the user interface, Arduino as the main controller, and software tools such as Arduino IDE, Visual Studio Code, and Android Studio. In addition, Firebase is employed as a database and an online data communication medium. The expected outcome of this study is the development of a system that can improve user awareness in conserving water and support more efficient and measurable water resource management.

Abstract

Water is one of the fundamental human necessities that plays a crucial role in supporting daily domestic activities. However, uncontrolled water consumption frequently results in excessive usage and increased household water expenditure. This study aims to design and implement a microcontroller-based water usage monitoring and control system to improve water-use efficiency and facilitate real-time monitoring. The proposed system utilizes the Wemos D1 R1 as the primary microcontroller integrated with a water flow sensor to detect water discharge, a water level sensor to monitor water levels in the storage tank, relays, a water pump, a solenoid valve, an LCD 20x4 display, and Firebase database integration for Android-based data communication and monitoring. The research methodology consists of analysis, design, testing, implementation, and maintenance stages. The implementation results demonstrate that the system is capable of monitoring water usage discharge, displaying water level information, and performing automatic control of the water filling process in the storage tank. The developed system is expected to improve household water-use efficiency and assist users in controlling water consumption more effectively and systematically.

Abstract

The development of an automatic floor-cleaning robot provides an innovative solution for addressing water puddles that frequently accumulate after rainfall. Although such puddles may appear insignificant, they can pose serious safety risks by increasing the likelihood of slip-and-fall accidents, particularly in public facilities such as mosques. This study presents the design and implementation of an ESP32-based automatic floor mopping robot intended to assist mosque caretakers (marbot) in maintaining floor cleanliness more efficiently and with reduced physical effort. The system was developed using the Software Development Life Cycle methodology with the Waterfall model, which consists of four sequential stages: planning, analysis, design, and implementation. The proposed robot integrates hardware and software components to perform automated floor-cleaning operations and can be controlled through a mobile application. System testing was conducted to evaluate functionality, reliability, and operational performance, as well as to verify that the developed system operated without significant errors and fulfilled the intended design objectives. The testing results demonstrated that the robot was capable of effectively mopping mosque floors, reducing the workload of mosque caretakers, and providing a practical and efficient cleaning solution. Consequently, the proposed system has the potential to improve both cleanliness management and user safety within mosque environments.

Abstract

The increasing use of mobile devices has led to a growing demand for charging facilities in public spaces, including coffee shops. This trend often results in uncontrolled electricity consumption, causing additional operational costs for business owners. This study aims to design and develop a website-based coin-operated charging station management system to enable real-time monitoring of electricity usage. The research adopted the Waterfall model within the System Development Life Cycle (SDLC), encompassing the phases of planning, analysis, design, testing, and implementation. The proposed system was developed using the CodeIgniter 3 framework, PHP, HTML, CSS, MySQL, and a web-based monitoring platform integrated with a coin sensor and an energy monitoring module. The results demonstrate that the system is capable of monitoring and displaying real-time electrical parameters, including current, power, voltage, and coin transaction data, while simultaneously storing the collected information in a database for historical monitoring and analysis. The developed system provides coffee shop operators with an efficient and reliable solution for monitoring electricity consumption, thereby supporting better energy management and reducing unnecessary operational costs.
