pada suhu 37ºc yang mensimulasikan konsumsi selama 5 bulan. setelah perendaman, spesimen diukur kembali menggunakan surface roughness tester. data yang diperoleh dianalisis menggunakan uji t berpasangan. hasil analisis menunjukkan tidakterdapat perbedaan yang signifikan kekasaran permukaan sebelum dan sesudah direndam dalam air rebusan daun kejibeling selama 1 hari 1 jam(p?0,05). kesimpulan dari penelitian ini adalah tidak terdapat pengaruh perendaman resin akrilik heat cured dalam air rebusan daun kejibeling terhadap kekasaran permukaan. kata kunci : kekasaran permukaan, resin akrilik heat cured, air rebusan daun kejibeling heat cured acrylic resin is a material that is commonly used as denture base. heat cured acrylic resin absorbs liquid that can increase the surface roughness. the result of phytochemistry test showed that kejibeling leaf boiled water contains phenolic coumpound. beside that, kejibeling leaf boiled water also contains calcium carbonate. phenolic compound and calcium carbonate which when in direct contact with the acrylic resin can affect to the surface roughness.the study aims to determine the effect of immersion of heat cured acrylic resin in the kejibeling leaf boiled water to surface roughness for 25 hours. the specimens in this study were 10 pieces and square shaped with size of 10 x 10 x 2 mm. each specimen was initially immersed in distilled water for 24 hours to reduce residual monomer and its initial roughness was measured using surface roughness tester. the specimen was then immersed in kejibeling leaf boiled water for 1 day 1 hour at 37ºc which simulates the consumption for 5 months. after immersion, each specimens measured using surface roughness tester to detemine the final roughness. the data was analyzed using paired t-test. the result showed no significant differences of surface roughness after immersion in kejibeling leaf boiled water for 1 day 1 hour (p?0,05). the conclusion of this study is that the immersion of heat cured acrylic resin in kejibeling leaf boiled water have no effect to surface roughness. keywords :surface roughness, heat cured acrylic resin, kejibeling leaf boiled
