Abstract

Using digital signature apps and communication platforms such as Discord has become essential in supporting teachers' administrative work in the digital era. Digital signature apps allow teachers to sign documents quickly, securely, and legally without meeting face-to-face. This speeds up the approval process of documents such as report cards, decision letters, and other administrative forms, thereby increasing efficiency and reducing reliance on physical documents. Initially developed for the gaming community, Discord has become an effective communication platform in educational settings. Features like voice chat, video calls, and discussion channel settings allow teachers to collaborate with colleagues, hold online meetings, and manage classes virtually. Their integration supports teacher productivity in daily administrative tasks, especially in remote work. Applying these technologies strengthens teachers' digital literacy skills, reduces their administrative burden, and allows them to focus more on developing the teaching-learning process. Thus, using digital signature apps and Discord is an essential part of digital transformation in the increasingly dynamic world of education.

Abstract

This community service initiative was designed to enhance teachers competencies in utilizing Google Workspace tools specifically Google Drive, Google Slides, and Google Forms to support the integration of digital learning. Conducted through an in-person workshop on February 11, 2025, the training targeted high school and vocational school teachers in the Bekasi region. The session emphasized mastery of essential features, including cloud-based file management, creation of engaging presentations, and the development of online surveys and assessments. The outcomes revealed that participants showed a significant improvement in their ability to operate these digital tools and expressed a strong intention to integrate them into their teaching practices. Overall, this activity contributed meaningfully to the advancement of digital transformation in secondary education settings.

Abstract

Computational thinking (CT) is a key 21st-century competency that needs to be developed from elementary school level because it is related to problem-solving skills, logical thinking, and creativity in the context of digital technology. Teachers play a central role in integrating CT into learning, but many elementary school teachers are unfamiliar with the concept of CT or its learning strategies. One effective approach that is appropriate for the characteristics of elementary school students is the CT-Unplugged activity, a computer-free activity that represents core computer science concepts in a concrete and enjoyable way. This community service activity aims to improve the understanding and skills of SDIT Mafatih teachers in implementing two CT-Unplugged modules: how binary digits work and checking product code digits (check digits), as a means of strengthening students' CT. The training was conducted at SDIT Mafatih involving 23 teachers through material presentations, demonstrations, activity simulations, and lesson plan design. Evaluation used pre- and post-tests of CT knowledge as well as questionnaires on perceptions and confidence in teaching CT. The results showed an increase in teachers' knowledge scores regarding CT concepts and binary digit/product code materials, as well as increased confidence in adapting CT-Unplugged activities into classroom learning. Teachers also produced several learning activity designs that integrated the module with elementary school lesson themes. This activity demonstrated that structured CT-Unplugged-based training is effective in building CT literacy and pedagogical capacity in elementary school teachers.

Abstract

The air quality in livestock barns significantly impacts the health and productivity of animals. This study designs an air quality monitoring system based on the Internet of Things (IoT) utilizing the ESP32 microcontroller and three gas sensors: MQ-135 (ammonia), MQ-4 (methane), and MQ-7 (carbon monoxide). The collected data is processed using the Fuzzy Sugeno logic method, which involves fuzzification, rule base, and defuzzification stages to classify the air conditions into Safe, Alert, or Dangerous categories. The classification results are displayed in real-time through an I2C LCD, the Blynk application, and the SmartENose website developed with PHP and MySQL. Additionally, the system is equipped with LED indicators and a buzzer for early warning notifications. Testing results indicate that the system can detect gas concentrations responsively and accurately, providing air status classifications that align with the actual conditions in the cattle barn. This research demonstrates that the application of IoT technology, supported by Fuzzy Sugeno logic, can be effectively utilized for monitoring and early warning of air quality in agricultural environments.
