Abstract

Communication between teachers and parents plays an important role in supporting early childhood education (ECE). However, at Hompimpaa Playschool, the communication medium used in the form of PDF-based liaison books has created several challenges, including time-consuming report preparation, static content, and difficulties in organizing and tracking children’s development records over time. This community service program aimed to assist the implementation of spreadsheets and Looker Studio as a more dynamic, efficient, and accessible digital liaison book. The program was conducted using a participatory mentoring and training approach through three face-to-face sessions, consisting of needs identification, core system training, and implementation assistance with evaluation. Teachers were guided to perform centralized data entry using spreadsheets, while parents were facilitated to monitor children’s development through a Looker Studio dashboard that can be filtered by date. The results indicate a shift in teachers’ workflow from preparing static PDF reports to a simpler and more structured data input process, as well as improved accessibility of information for parents without the need to repeatedly download report files. In addition, a practical user guide module was developed to support program sustainability. This activity demonstrates that the application of simple digital technologies, when accompanied by proper mentoring, can enhance teacher–parent communication, reduce teachers’ administrative workload, and has the potential to be replicated in other early childhood education institutions facing similar challenges.

Abstract

This community engagement program aims to support the implementation of a digital-based selection system for village apparatuses, specifically in the selection of hamlet heads (Kepala Dusun) in Karanggintung Village, Banyumas Regency. The process was carried out through a partnership between Telkom University Purwokerto and the village government, utilizing a Computer Assisted Test (CAT) system based on the Moodle Learning Management System (LMS). The activity covered the full cycle from technical setup, simulation, question input, to the digital exam execution for 16 candidates. The system successfully ensured transparency and objectivity through automatic scoring and real-time ranking. However, none of the participants achieved the minimum passing grade of 65, highlighting the gap between digital assessment standards and participant readiness. Despite the zero-passing result, participant satisfaction remained high, with most expressing strong agreement on the effectiveness of the process. This indicates public acceptance of digital mechanisms when implemented transparently and professionally. The case offers important insights into the intersection of digital governance, rural capacity, and democratic values at the local level.

Abstract

Limited internet service quality remains a major challenge in community-based RT/RW Net networks that rely on copper cables, mainly due to their vulnerability to lightning strikes and technical disturbances. This condition affects educational activities, religious services, and community-based economic activities, including home-based micro-enterprises and digital religious outreach. This community service program aims to modernize network infrastructure through the implementation of fiber optic technology that provides higher stability, safety, and sustainability, while strengthening local capacity in network management through technical and managerial training for youth groups. The implementation stages include coordination with community partners, deployment of fiber optic networks, network planning simulation using OptiSystem to ensure optical attenuation remains within safe limits, training on RT/RW Net management supported by cloud-based documentation systems, and hands-on training on fiber optic installation and MikroTik router configuration. The results show that the fiber optic network has been successfully implemented and currently serves 11 households and one mosque that regularly utilizes internet access for weekly live-streamed religious lectures. From a technical perspective, the fiber optic infrastructure improves network stability and reduces the risk of equipment damage caused by lightning. From social and economic perspective, reliable internet access supports distance learning, digital religious activities, and the operation of home-based micro-enterprises. The active involvement of local youth in installation and training activities enhances local technical capacity and contributes to the sustainability of the RT/RW Net system. This program demonstrates that fiber optic deployment combined with community empowerment can serve as an effective model for community-based digital infrastructure development.

Abstract

Corn (Zea Mays L.) faces challenges from leaf diseases, which become severe when farmers lack the expertise to recognize and manage them. This study presents a comparative analysis of VGG16 and VGG19 architectures for detecting corn leaf diseases, highlighting their performance under standardized conditions using transfer learning. The novelty of this study lies in the direct benchmarking of both models across multiple image resolutions and training epochs, which has not been comprehensively explored in previous studies. The system categorizes diseases based on images, thereby helping farmers manage corn leaf diseases more effectively. The VGG16 architecture was chosen for its balance of depth and computational efficiency, while VGG19 offers higher accuracy due to its increased layer depth and complexity. This system is expected to assist farmers in detecting corn leaf diseases more efficiently and accurately than previously possible. The dataset used in this study consists of 4198 images, divided into four categories: Healthy, Blight, Common Rust, and Gray Leaf Spot. The dataset was split into 80% for training and 20% for testing purposes. The classification results using 2 architectures, VGG16 and VGG19, with the use of the SGD optimiser, show that VGG19 outperforms VGG16. The VGG19 model demonstrated a performance level of 92.74% accuracy, alongside 91% for precision, recall, and F1-score. In comparison, VGG16 achieved a slightly lower accuracy of 92.62%, with precision at 91%, recall at 89%, and an F1-score of 90%. This performance variance is attributed to the architectural depth, as VGG19 utilizes 19 layers while VGG16 is limited to 16. Ultimately, this tool aims to provide farmers with a more precise and streamlined method for identifying corn foliage conditions.
