Charles Sanders Peirce's Semiotic Approach in Analyzing the Architecture of the Baiturrahman Grand Mosque Banda Aceh

The concept of semiotic architecture is widely used in historical and contemporary buildings such as large-volume buildings, one of which is a mosque. The Baiturrahman Grand Mosque in Banda Aceh is one of the icons of Islamic architecture in Indonesia that can be studied using the concept of Charles Sanders Peirce semiotics. The Baiturrahman Grand Mosque represents religious symbols, culture, and the struggle of the Acehnese people in addition to being a site of worship for Muslims. The application of Peirce's semiotic approach in analyzing the architecture of the Baiturrahman Grand Mosque paves the way for a more comprehensive understanding of the relationship between icons, indices and symbols in the context of Islamic architecture. This analysis not only enriches our appreciation of the aesthetic beauty and cultural values contained in mosque architecture, but also provides greater insight into the role of architecture in shaping identity and collective memory. The research methodology in this study includes a descriptive qualitative technique and a literature review. The study's findings obtained 7 data which include 4 icon data consisting of domes, umbrellas, mihrabs, and flower carvings. 1 index data in the form of the main tower of the mosque. And 2 symbol data, namely the black color on the mosque dome and the white color in the mosque room.
