This material was created by Ameilya Anggie Dyah Risyadi, Rinkamonic Putri Alfajri, and Anna Christivita Josef Viernita Dipasto, under the supervision of Adi Satrio Ardiansyah, S.Pd., M.Pd., to address challenges in mathematics learning that is often perceived as abstract and lacking in context.<\/p>\n\n\n\n<p>NUMERA BATIKA adopts an ethnomathematics approach by using Semarang batik motifs such as <em>Tugu Muda<\/em>, <em>Lawang Sewu<\/em>, and <em>Warak Ngendog<\/em> as learning media. Prime factors are taught through the analysis of symmetrical patterns in batik motifs, similar to how artisans calculate factors to achieve geometric harmony. Ratios and scale are explored by calculating the proportions of elements such as the size of birds or flowers within batik designs. Proportion and rate of change are examined through the transformation of batik patterns over time, connecting abstract theory to real-world contexts. This approach enhances students\u2019 conceptual understanding of numerical material as well as 21st-century skills such as problem-solving, critical thinking, and creativity.<\/p>\n\n\n\n<p>The development of NUMERA BATIKA is in line with the Sustainable Development Goals (SDGs), particularly Goal 4 on Quality Education. This innovation not only makes mathematics learning more engaging and relevant but also helps preserve the cultural heritage of Semarang Batik for younger generations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"724\" src=\"https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-1024x724.png\" alt=\"\" class=\"wp-image-5852\" style=\"width:472px;height:auto\" srcset=\"https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-1024x724.png 1024w, https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-300x212.png 300w, https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-768x543.png 768w, https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-1536x1086.png 1536w, https:\/\/unnes.ac.id\/sdgs\/wp-content\/uploads\/sites\/34\/2025\/11\/NUMERA-BATIKA-AMEILYA-ANGGIE-DYAH-RISYADI-2048x1448.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>A research team from Universitas Negeri Semarang has developed an innovative teaching material titled NUMERA BATIKA, which integrates mathematics with Semarang batik culture.
