This study aims to design a steel roof truss, plan the profile and size of the profile purlins and horses, the diameter of the track, the diameter of the wind ties, plan the connection and gusset plate, also analyze the output/results of structural strength calculations on steel roof trusses. The research method used is to plan and analyze the structure with the help of autocad software to design, loads are calculated manually, and also use SAP 2000 software to analyze the calculation results of the steel roof truss structure. From this study, the calculation results obtained which states that the planning of steel roof truss structure using light Lip channels gording profile measuring [200.75.20.3](200.75.20.3), 2, trekstang using iron diameter 12 mm, wind ties using iron diameter 19 mm, Double Angle easel profile measuring 2L.90.90.7 (used on rootstock, upright stems, and diagonal stems), 2L.90.90.13 (used on the upper diagonal rods), and the calculation of Bolt connections as many as 3 bolts in each rod, which have been calculated to be strong, safe, and also sturdy in withstanding the loads that work on the roof frame  \nINTRODUCTION  \nIn recent years, construction development in Indonesia has continued to grow over time, this is influenced by several factors including stable and strong economic growth, infrastructure investment, construction technology innovation, urbanization, sustainable development, regulations and policies, and earthquake resistance. One of the structural materials that is earthquake resistant is steel, because steel has high tensile strength that can withstand dynamic loads from earthquakes. In addition, the elastic properties of steel can cause steel to experience temporary deformation during an earthquake and then return to its original state which can prevent permanent damage to the structure of a building.  \nSteel is a type of metal alloy consisting of a mixture of the main elements iron and carbon, and several other elements are added to increase its strength and properties. The steel making process is carried out with guaranteed quality standards, ensuring the availability of various types of steel that are in accordance with the needs and purposes of its use (Putra, FA, & Setiawan, B., 2023). Steel is a material that can be easily shaped according to needs, so it is often the main choice. The quality of steel is guaranteed in the production process, there are various types of steel that are suitable for its needs (Wiseno, E., Irwandi, MA, 2023) . The strength of steel material in withstanding loads is greatly influenced by its mechanical characteristics. Mechanical properties include the capacity of the material to withstand pressure from the working loads (Arifi. E., Setyowulan., 2020) . One of the advantages of steel as a structural material is its high strength and tensile strength, as well as the ease and practicality of its installation.
