Despite the rich potential of local cultural resources to contextualise biology learning, many teachers still have limited experience and practical support to translate local wisdom into structured SSI-oriented instructional modules. This community service programme aimed to strengthen senior high school biology teachers’ capacity to design Socioscientific Issues (SSI)-based teaching modules by integrating local wisdom from Sasirangan cloth (motifs and natural dyes) and a supporting digital platform (Sasirangan Verse). The three-day workshop involved 30 biology teachers from 15 senior high schools in Banjarmasin City (MGMP Biology). Training activities combined concept building on SSI and deep learning, local-context exploration (natural dye plants and environmental-health issues of synthetic dyes), collaborative module writing, peer feedback, and initial validation. Programme data were collected through documentation and a post-workshop questionnaire (7 items). Descriptive results showed uniformly positive responses: for most items, 50.0–60.0% of participants selected ‘strongly agree’ and the remainder selected ‘agree’. The highest endorsement was reported for integrating local wisdom (60.0% strongly agree) and fostering critical thinking (60.0% strongly agree), while readiness to adapt modules in schools was positive but more cautious (73.3% agree; 26.7% strongly agree). Overall, the programme produced SSI-based module prototypes (including LKPD, assessment rubrics, and metacognitive journals) and indicated strong acceptability, suggesting the need for follow-up mentoring to support classroom implementation.
