Traditional textile SMEs still rely on manual processes, resulting in inefficiencies in production and data management. This study proposes a cost-conscious digitalization framework that integrates Cyber-Physical Systems (CPS), a lightweight information layer, and artificial intelligence (AI), specifically designed for labour-intensive textile operations. The framework adheres to the ISA-95 architecture, emphasizing affordability and scalability. Stakeholder interviews, business process reengineering, and a three-month field implementation were conducted in a textile hub in Bandung. Key digital tools, including e-kiosks for real-time logging, integrated digital scales for inventory management, and mobile vision-based quality control using convolutional neural networks (Xception and VGG), were evaluated through an immersion study and user acceptance testing. Evaluation results show improvements in workflow visibility, data reliability, and consistency of quality inspection compared to the pre-digitalized process, while maintaining ease of use for operators. Evaluation results indicate qualitative operational improvements—such as enhanced workflow visibility, more reliable data capture, and more consistent quality inspection—reflecting meaningful enhancements observed during the digitalization pilot. The study contributes a replicable CPS–AI model that enables traditional SMEs to enhance efficiency and quality through scalable digital transformation.

Small and medium enterprises (SMEs) often struggle to adopt advanced inventory management systems due to high implementation costs and infrastructure complexity—barriers that are especially challenging in the context of Industry 4.0. This paper presents a scalable and affordable IoT-based stock monitoring and control system designed for small and medium enterprises. The proposed system integrates low-cost microcontrollers with ultrasonic sensors, enabling real-time stock tracking while reducing hardware expenses and complexity. Unlike existing solutions, it leverages a modular architecture for seamless scalability across different inventory sizes and environments. The system is validated through compliance with the Industry 4.0 Maturity Index and the ISA-95 standard, demonstrating its suitability for digital transformation in SME operations. Performance evaluation shows an accuracy rate exceeding 98% and response times under 10 seconds, ensuring reliable operation under varying environmental conditions. A comparative cost analysis highlights significant savings compared to conventional automated inventory systems. This approach provides an accessible entry point for SMEs seeking to enhance inventory visibility, operational efficiency, and readiness for Industry 4.0 integration.

Industry 4.0's pervasive digital ideas have completely changed how businesses operate. A lot of big businesses have switched to digital systems. However, due to a lack of funding and digital infrastructure, SME sector digitalization issues still exist. Inventory management is one of the many manual methods that many SMEs still have to rely on, which makes it prone to error. To manage inventories more accurately and effectively, manual systems must be changed. The goal of this project is to improve inventory management efficiency by creating a dependable and affordable automated system. A cloud database is connected to the system to provide quick inventory monitoring on warehouse shelves. Prototyping and statistical testing are used in the study technique to evaluate the system's dependability. Using an Internet of Things-based single-board computer, the research creates an inventory monitoring system. With a daily implementation cost of IDR 642.92, the system is deemed cost-effective based on inventory monitoring results on warehouse shelves. Because the system's performance reached a Cronbach's alpha value greater than 0.8, the inventory management system used in the study is regarded as dependable for application in real-world systems to increase inventory management accuracy

The growing demand for sustainable energy solutions has highlighted the importance of renewable energy technologies, particularly in urban and semi-urban communities. In Rangkapan Jaya Village, Depok, the lack of adequate street lighting and limited awareness of green energy solutions have created both environmental and safety challenges. This project contributes a replicable model for integrating solar-powered street lighting (PJUTS) into underserved communities using a participatory approach. It also provides a practical framework for community-based training in renewable energy technology, promoting both infrastructure development and environmental education. The activity began with a socialization session explaining the principles and benefits of renewable energy and solar panels. This was followed by hands-on technical training on the installation of PJUTS systems, involving local residents directly in assembling and deploying the equipment in targeted areas. Participants demonstrated increased understanding of solar panel operation and installation. Several solar-powered streetlights were successfully installed, improving lighting in previously unlit areas. Community feedback indicated heightened interest in renewable energy solutions and greater confidence in maintaining the system independently. The project shows that a community-based, educational approach is effective in promoting green technology at the local level. It addressed both practical infrastructure needs and capacity-building, offering a scalable solution for other regions seeking sustainable energy implementation.Peningkatan kebutuhan terhadap solusi energi berkelanjutan mendorong pemanfaatan teknologi energi terbarukan, khususnya pada lingkungan masyarakat perkotaan dan semi-perkotaan. Di Kelurahan Rangkapan Jaya, Depok, keterbatasan fasilitas penerangan jalan serta rendahnya pemahaman masyarakat mengenai konsep energi hijau menjadi tantangan yang berdampak terhadap aspek lingkungan dan keamanan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menerapkan sistem penerangan jalan umum tenaga surya (PJUTS) berbasis sensor cahaya sekaligus meningkatkan pengetahuan dan keterampilan masyarakat dalam pemanfaatan teknologi energi terbarukan melalui pendekatan partisipatif. Metode pelaksanaan kegiatan meliputi sosialisasi mengenai prinsip kerja dan manfaat energi terbarukan, pelatihan teknis instalasi sistem PJUTS, praktik perakitan perangkat, serta pemasangan sistem penerangan pada lokasi yang telah ditentukan. Kegiatan ini melibatkan masyarakat secara langsung dalam proses instalasi dan pemeliharaan sistem. Hasil kegiatan menunjukkan bahwa peserta mengalami peningkatan pemahaman terkait prinsip kerja panel surya, sensor cahaya, dan sistem penyimpanan energi. Selain itu, beberapa unit penerangan berbasis energi surya berhasil dipasang dan mampu meningkatkan pencahayaan pada area yang sebelumnya minim penerangan. Kegiatan ini menunjukkan bahwa pendekatan edukatif berbasis partisipasi masyarakat efektif dalam mendukung penerapan teknologi hijau di tingkat lokal. Implementasi PJUTS tidak hanya memberikan solusi terhadap kebutuhan infrastruktur penerangan, tetapi juga meningkatkan kapasitas masyarakat dalam mendukung pemanfaatan energi berkelanjutan

Industri skala kecil membutuhkan sistem monitoring produksi yang sederhana dan terjangkau untuk mendukung digitalisasi. Namun, pencatatan data produksi masih sering dilakukan secara manual sehingga analisis bottleneck menjadi kurang efektif dan cenderung subjektif. Penelitian ini mengembangkan sistem monitoring produksi berbasis IoT pada lini produksi eksperimental menggunakan ESP32, barcode scanner, koneksi Wi-Fi, Apps Script, dan Spreadsheet sebagai media penyimpanan data berbasis cloud. Sistem digunakan untuk merekam parameter produksi berupa cycle time, idle time, throughput, dan WIP. Hasil pengujian menunjukkan bahwa sistem mampu mencatat, memproses, dan mengirimkan data produksi secara real-time dengan tingkat ketepatan yang baik, sehingga analisis performa produksi dapat dilakukan secara lebih objektif, cepat, terukur, dan mendukung pengambilan keputusan operasional. Dengan demikian, sistem yang dikembangkan memantau data produksi secara real-time, sehingga stasiun dengan cycle time tertinggi dapat diidentifikasi sebagai bottleneck utama secara objektif, sekaligus menunjukkan potensi penerapan smart manufacturing pada lingkungan produksi skala kecil.
