Abstract

The third millennium is marked by rapid advancement of technological development is very fast in all areas, therefore people in this world began working to create new innovations in order to support its activities a day - which in recent hari.Teknologi developing very rapidly and become a worldwide concern is the development of Information Technology (IT) which is a combination of Computer Technology and Communication Technology.With this technology, more and more organizations or companies who started to use and exploit information technology to conduct its business as it is more effective and efficient than the magnitude of the costs if done manually. Transitional or developing an existing system, expected to occur perubahanataupeningkatan so the results are more optimal performance because the error rate would be reduced drastically.Planning a systematic and mature from an activity is a basic characteristic of modern industry, because basically effective planning of materials, machinery, and money will be towards the acquisition of profit is so important in a company. Along with the development of an enterprise is to face the above mentioned factors should be considered a material planning system that can support the production of all production activities as one step in the process of decision making. PT X is an object that is taken because it is considered as one business unitwho always want improvement and progress in his ministry and his own business. Along with the development of technology, many problems that occur relating to the implementation of asset management systems in PT. X.Keywords: analysis, design, information systems

Abstract

The Knowledge in a study program or faculty at Higher Education is an asset that must be utilized by universities. Explicit knowledge can be in the form of meeting attendance, meeting schedules, minutes of meetings, teaching materials, documentation of the final session, letters (SK, ST, contract letters, etc.), certificates, reports, guidelines, manuals , memos, strategic plans, curriculum and so on. However, knowledge cannot be easily accessed by cross study programs or cross faculties at the college. Some study programs have done documentation so well that it has an impact on satisfying accreditation assessments. Study programs that have satisfactory accreditation can be an example for other study programs. A knowledge management system is needed to bridge the distance between study programs that have good governance and others. The results of the knowledge management system testing allow for the exchange of knowledge to become a means of improving the quality of governance both at the study program level and at the faculty level.

Abstract

This study presents an innovative approach to enhance apple leaf disease detection using deep learning by comparing three models: ReXNet-150, EfficientNet, and Conventional CNN (ResNet-18). The objective is to identify the most accurate and efficient model for real-world deployment in resource-constrained environments. Utilizing a dataset of 1,730 high-quality images, the models were trained using transfer learning, achieving significant results. ReXNet-150 outperformed other models with an F1-score of 0.988, precision of 0.989, and recall of 0.989. EfficientNet and ResNet-18 demonstrated competitive performances with F1-scores of 0.966 and 0.977, respectively. The integration of the ReXNet-150 model into a TensorFlow Lite-based Android application ensures real-time detection, enabling farmers and researchers to capture or upload images for immediate classification. The findings highlight ReXNet-150's robustness, achieving a test accuracy of 98.9% and minimal misclassification, making it ideal for practical agricultural applications. The novelty lies in bridging advanced deep learning with mobile deployment, addressing real-world constraints. Future work could extend this framework to multi-crop disease detection and real-time video analysis, providing scalable solutions for precision agriculture.

Abstract

Gereja Kristen Indonesia (GKI) Maleo Raya menghadapi tantangan dalam pengelolaan administrasi jemaat yang masih bergantung pada pencatatan manual, sehingga menimbulkan risiko redundansi data, kehilangan arsip, serta keterlambatan dalam penyusunan laporan. Kegiatan pengabdian masyarakat ini bertujuan merancang dan menerapkan sistem informasi administrasi berbasis web responsif untuk meningkatkan efisiensi, akurasi, dan keamanan pengelolaan data gereja. Pengembangan sistem menggunakan metode Waterfall melalui tahapan analisis kebutuhan, perancangan, implementasi, dan pengujian. Sistem dilengkapi autentikasi One-Time Password (OTP) guna memperkuat keamanan akses dan mendukung kemudahan penggunaan bagi staf Kantor. Hasil implementasi menunjukkan bahwa aplikasi mampu mengelola database jemaat, mencatat sakramen, serta menghasilkan laporan statistik secara otomatis, dengan peningkatan kualitas layanan administrasi lebih dari 90%. Digitalisasi administrasi yang aman dan mobile-ready ini menjadi langkah strategis bagi gereja dalam mewujudkan pelayanan yang lebih efisien, responsif, dan transparan.

Abstract

Membership administration is a fundamental component of effective church governance. GKI Maleo faces challenges in managing congregational data due to the continued use of manual record-keeping systems, which leads to risks of data loss, duplicated information, and difficulties in data management. This community service activity aims to assist GKI Maleo in reorganizing its membership administration through the development of a membership data website that includes features for personal data, family information, sacramental records, membership transfers, and service history. The implementation method includes needs analysis, system design, website development, user training, as well as monitoring and evaluation. The results show a significant improvement in data accuracy, efficiency in data retrieval, and the church administrators’ ability to manage congregational information digitally. The development of this website provides a tangible contribution to the modernization of church administration and enhances the quality of services provided to the congregation.
