We are pleased to announce that Volume 23, Issue 2 of the Jurnal Optimasi Sistem Industri (JOSI) is now available on our website. We appreciate your patience during our recent server issues, which delayed this publication by a month. Our technical team worked diligently to resolve the problem by migrating to a new server, and we are delighted to have overcome the challenges to bring you this latest edition.

This issue features a diverse collection of cutting-edge research that addresses critical challenges in industrial systems across the globe. With contributions from experts in Indonesia, Taiwan, Palestine, Brazil, Malaysia, Egypt, and Japan, this edition embodies the power of interdisciplinary and cross-national collaboration. The articles cover a wide range of topics—from machine learning applications in supply chain management and hybrid multi-criteria decision-making frameworks to the implementation of advanced techniques such as Statistical Process Control (SPC), Failure Mode and Effects Analysis (FMEA), and Mixed Integer Linear Programming (MILP).

A significant theme throughout this issue is the balance between industrial efficiency and sustainability. You will find innovative studies on optimizing recycling networks for electric vehicle batteries in Southeast Asia and developing sustainable assessment models for plywood manufacturing. Additionally, traditional industries, such as Indonesian batik production, are explored with modern quality control practices that preserve cultural heritage while enhancing competitiveness.

Our contributors also tackle important subjects such as demand forecasting with machine learning, sustainable logistics service quality, and the selection of open-source ERP systems for SMEs. Each study not only enriches the field of industrial engineering but also reinforces our commitment to promoting sustainable development in alignment with the United Nations Sustainable Development Goals.

We extend our sincere gratitude to the authors, reviewers, and our dedicated editorial team for their exceptional work. Their contributions ensure that JOSI continues to serve as a high-quality platform for advancing industrial engineering knowledge and practice.

We invite you to explore this issue and discover insights, innovations, and actionable solutions that are poised to inspire further research and applications in industrial systems optimization worldwide.

Sincerely,
Editor-in-Chief
