Technological advancement is inextricably linked to the advancement of human civilization. Fashion accessories are a result of human civilization. Through this article, we will describe one endeavor to advance and broaden the range of jewelry designs is the use of Escher's tessellation modular design to fashion accessories at LORI (Laras Ornamen Indonesia) MSME. LORI is also a place for project-based learning by design students from Universitas Kristen Maranatha and Telkom University in the practice of making lecture assignments. This study used a qualitative methodology based on an experimental case study using metallic tools and materials. The result of this experiment is the design of a jewelry accessory prototype using the Lasem batik motif as a local source of inspiration for the design's content and the modular tessellation technique. It is hoped that the outcomes of this prototype will serve as a guide to improve the design features and marketing of LORI MSME products.
