Trikalsium silikat (C3S) merupakan komponen utama pada material bioceramic sealer endodontik yang berperan dalam menghasilkan obturasi saluran akar yang hermetis. Sifat fisikokimia seperti setting time dan flowability menjadi parameter penting yang menentukan kualitas sealer. Penelitian ini bertujuan menganalisis pengaruh variasi rasio powder/water (p/w) terhadap setting time dan flowability trikalsium silikat berbahan dasar batu gamping (limestone) Aceh pada dua komposisi bubuk, yaitu C3S 31 dan C3S 41. Penelitian dilakukan secara eksperimental laboratorik menggunakan tiga variasi rasio p/w, yakni 5:4, 5:5, dan 5:6. Setting time diukur menggunakan jarum vicat sesuai standar pengujian semen hidrolik, sedangkan flowability diukur berdasarkan metode ISO 6876:2012 menggunakan kaliper digital. Data setting time dan flowability dianalisis menggunakan uji Independent t-test dan one-way ANOVA. Hasil penelitian menunjukkan bahwa variasi rasio p/w berpengaruh signifikan terhadap setting time pada kedua komposisi bubuk. C3S 31 memiliki setting time tercepat pada rasio 5:5, yakni 140,3 menit, sedangkan C3S 41 menunjukkan setting time terlama pada rasio 5:6, yakni 191,3 menit. Pada parameter flowability, variasi rasio p/w tidak menunjukkan pengaruh signifikan pada C3S 31, namun berpengaruh signifikan pada C3S 41. Secara umum, C3S 41 memiliki nilai flowability lebih tinggi dibandingkan C3S 31 pada seluruh rasio. Kesimpulan dari penelitian ini adalah variasi rasio p/w berpengaruh terhadap setting time dan flowability pada trikalsium silikat berbahan dasar limestone Aceh.

Tricalcium silicate (C3S) is the main component in endodontic bioceramic sealer and plays a crucial role in achieving hermetic root canal obturation. Physicochemical properties, particularly setting time and flowability, are key parameters that determine the quality of the sealer. This study aims to analyze the effect of powder/water (p/w) ratio variations on the setting time and flowability of tricalcium silicate based on Aceh limestone in two powder compositions, namely C3S 31 and C3S 41. This laboratory experimental study used three p/w ratio variations, namely 5:4, 5:5, and 5:6. Setting time was measured using a vicat needle according to hydraulic cement testing standards, while the flowability was measured based on ISO 6876:2012 method using a digital caliper. The results of the setting time and flowability tests were analyzed using the Independent t-test and one-way ANOVA. The results showed that the variation in the p/w ratio had a significant effect on the setting time of both powder compositions. C3S 31 had the fastest setting time at a ratio of 5:5, namely 140.3 minutes, while C3S 41 showed the longest setting time at a ratio of 5:6, namely 191.3 minutes. In terms of flowability, the variation in the p/w ratio did not show a significant effect on C3S 31, but had a significant effect on C3S 41. In general, C3S 41 had a higher flowability value than C3S 31 at all ratios. The conclusion of this study is that variations in the p/w ratio affect the setting time and flowability of tricalcium silicate based on Aceh limestone
