Abstract

UMKM Batik Tulis Shiha Ali di Kabupaten Tulang Bawang, Lampung, menghadapi dua permasalahan utama, yaitu limbah cair berbahaya dari proses pewarnaan batik yang belum dikelola secara efektif serta strategi pemasaran digital yang belum optimal, terutama dalam memberdayakan pekerja disabilitas. Untuk menjawab permasalahan tersebut, dilakukan program pemberdayaan melalui penerapan teknologi pengolahan limbah berbasis elektrokoagulasi dan filtrasi bioremediasi serta pelatihan digital marketing. Metode pelaksanaan menggunakan pendekatan partisipatif, edukatif, dan aplikatif, yang meliputi sosialisasi, pelatihan teknis, penerapan teknologi, dan pendampingan. Hasil menunjukkan bahwa sistem pengolahan limbah mampu menurunkan kadar COD dan BOD hingga 80%, meningkatkan kualitas air buangan, dan mendorong kesadaran lingkungan pekerja. Sementara itu, pelatihan pemasaran digital meningkatkan keterampilan pekerja disabilitas dalam mengelola media sosial dan marketplace, serta meningkatkan omzet penjualan hingga 37% dalam waktu empat bulan. Kesimpulannya, integrasi teknologi ramah lingkungan dan literasi digital mampu memperkuat keberlanjutan produksi, meningkatkan daya saing usaha, dan memberdayakan kelompok rentan secara ekonomi dan sosial. Program ini layak direplikasi pada UMKM lain yang menghadapi tantangan serupa dalam ekosistem industri kreatif berbasis budaya.

Abstract

This research presents the development of a teleoperation system for a mecanum wheel robot actuation integrated with the MQTT (Message Queuing Telemetry Transport) protocol to be used as an interactive STEM (Science, Technology, Engineering, and Mathematics) learning tool. The system employs four independently actuated mecanum wheels enabling omnidirectional mobility through coordinated wheel control. The teleoperation architecture utilizes a Raspberry Pi 3B+ connected to HiveMQ Cloud broker implementing MQTT protocol for real-time remote actuation via Flutter-based mobile interface. Each wheel actuation is controlled through L298N motor drivers operating at 300Hz PWM (Pulse Width Modulation) frequency, providing precise speed and directional control. Experimental results demonstrate system reliability with an average position deviation of 1.86 cm for forward actuation, 1.93 cm for backward, 2.64 cm for left slide, and 1.71 cm for right slide movements across 140 cm distance. The MQTT integration achieves a command execution latency of 200-400ms, suitable for educational teleoperation applications. The Flutter interface provides intuitive control with real-time visualization of wheel actuation states, enhancing user understanding of mecanum wheel kinematics. This implementation successfully demonstrates the effective use of teleoperation of a mecanum wheel robot actuation as platform for interactive STEM education, providing hands-on experience in robotics actuation, IoT protocols, control systems, and mobile application development.
