Abstract

This community service activity aims to integrate Internet of Things (IoT) technology into the monitoring system of a Microhydro Power Plant (PLTMH) in Argamukti Village, Majalengka Regency. The village has significant renewable energy potential, but challenges in real-time energy production monitoring have hindered the plant's optimal performance. By implementing an IoT-based monitoring system, the operational efficiency of the PLTMH can be significantly improved. This program includes training in IoT device installation and guidance for local communities in operating and maintaining the system. The results show a 20% increase in energy production efficiency compared to the period before the monitoring system was implemented. Furthermore, the local community is empowered to manage energy resources independently, supporting the establishment of Energy Self-Sufficient Villages. This initiative aligns with government efforts to promote renewable energy usage in rural areas. The IoT technology implementation also opens opportunities for applications in other sectors such as smart farming and water management, which can sustainably enhance the local community's welfare.

Abstract

The increasing volume of domestic wastewater, particularly greywater, has raised the demand for intelligent and adaptive treatment systems to support efficient water reuse. This study aims to develop a classification model for filtration media types (physical, chemical, and biological) based on water quality data using the Random Forest algorithm. Initial labeling was conducted using the K-Means Clustering method on a publicly available dataset simulated as greywater, based on ten key water quality parameters relevant to irrigation and environmental standards. Model evaluation demonstrated excellent classification performance, with a macro F1-score reaching 0.97 and consistent results in both 5-fold and 10-fold cross-validation. These findings indicate that the proposed model can be integrated into an IoT-based biofiltration system as an automated classification logic to support adaptive, efficient, and reusable household wastewater treatment in the context of irrigation.

Abstract

Employee absenteeism is a very important factor in a company or agency. The punctuality and integrity of employees who are assessed will help the development of the institution/institution. An attendance system that has up-to-date software is very important, because it has positive benefits for the institution or agency, especially interms of effectiveness, efficiency and speed. Along with that attendance is also not only done manually, but can help by using information technology. Attendance carried out at the Office of the KB Sub-District of Pengingkiran is still done manually, namely employees fill in attendance with signatures as well as the time of arrival and departure time. So, there are still a lot of problems when using the manual attendance system, such as not entering without information, coming and going home from the office not according to regulations, leaving the office during working hours and not knowing the leadership and there are still many problems caused. So that the KB Office of the Pengingkiran District requires an attendance application. With the application of the Employee Attendance Data Processing Information System, the Panyingkiran District Family Planning Office was able to overcome the occurrence of absenteeism violations in employees.

Abstract

The Lembah Cisaar Museum in Sumedang, West Java, which exhibits ancient animal fossils, faces challenges in attracting visitors due to limited interactivity and less engaging presentation methods. This study aims to improve the visitor experience through the development of an Android-based Augmented Reality (AR) application. The research employs the Multimedia Development Life Cycle (MDLC) method, consisting of concept, design, material collecting, assembly, testing, and distribution, combined with usability testing. The developed application integrates 3D fossil visualizations, interactive markers, and voice-over narration using Unity, Blender, and Vuforia. Usability testing involving 40 respondents indicated that 89% of users found the application engaging, 91% reported increased interest in visiting the museum, and 92% considered the information beneficial. These findings demonstrate that AR technology can significantly enhance educational value, interactivity, and visitor engagement. The implementation of this AR application provides a modern digital solution to introduce cultural heritage, supporting the transformation of museums into accessible and technology-based educational platforms

Abstract

This study aims to design and implement an automated WhatsApp bot system based on Node.js and the Baileys library, equipped with a web dashboard as a management interface without requiring a Command Line Interface (CLI). The research method follows the Waterfall model, encompassing requirements analysis, system design, implementation, Black-Box testing, and maintenance. Implementation results demonstrate that the WhatsApp bot can automatically respond to customer messages based on keywords, accelerate the sales process of premium digital applications, and improve customer service efficiency at the Untitled store. The web dashboard enables administrators to control the bot and manage message templates more flexibly. The study concludes that the developed system is effective in streamlining digital account sales operations and provides a foundation for further enhancements such as automatic payment integration and the application of Natural Language Processing (NLP).

Abstract

The rapid development of digital technology has brought significant changes to tourism promotion strategies, with websites becoming one of the most effective media for delivering information quickly, accurately, and in a well-structured manner. Zarind Waterboom, a water tourism destination in Majalengka Regency, still faces challenges in its promotional efforts due to limited media usage and a lack of informative content. This study aims to design and implement a website-based information system to improve information accessibility and enhance visitor interest. The research methodology includes literature review, needs analysis, system design using the waterfall approach, and website implementation with HTML, CSS, and PHP. The results indicate that the developed website successfully provides key information such as ticket prices, facilities, location photos, and an interactive map to help visitors easily find the destination. The presence of this website enables the management to expand its promotional reach, improve interaction with potential visitors, and strengthen its digital marketing strategy. This research is expected to serve as a practical solution for Zarind Waterboom’s management in optimizing tourism promotion and attracting more visitors.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in regional economic growth and job creation, yet data collection in Majalengka remains largely manual, resulting in outdated and inconsistent information. This study aims to design and implement a web-based MSME data collection system at the Majalengka Creative Center to improve efficiency, accuracy, and accessibility of information. The system was developed using the Rapid Application Development (RAD) methodology, which emphasizes user involvement and iterative prototyping for faster and more adaptive development. The implementation utilized Next.js for the frontend and MongoDB as the database, enabling MSME actors to independently register, update, and manage their business profiles, while administrators can verify data, manage events, and generate statistical reports. Black-box testing with equivalence partitioning was conducted to evaluate functionality, with results showing that the system successfully supports registration, verification, and information dissemination processes, although some test cases revealed areas for improvement. Overall, the web-based system effectively reduces reliance on manual surveys, accelerates data validation, and enhances government capacity to deliver targeted training and assistance programs. This research demonstrates that digital solutions can strengthen transparency, optimize MSME empowerment, and support data-driven policy-making for sustainable local economic development.
