Abstract

Indonesia is a country that is vulnerable to natural disasters, one of which is an earthquake. Because Indonesia is at the meeting point of the 3 most important major plates in the world, one of the effects of the earthquake is damage to building structures. Structural planning is needed for buildings with earthquake resistance from the many occurrences of earthquakes seen in recent times and the losses incurred.Pushover analysis is a non-linear static analysis. The static load captured at the center of mass of each floor is taken into account in this pushover analysis as the effect of the design earthquake on the building structure, the aim of which is to find out how the building structure will collapse during an earthquake so that you can know which parts of the structure are in critical condition and what to do if they do not meet the requirements.The results of the analysis show that the maximum base shear force for the x direction capacity curve is 484.6749 tons with a displacement of 0.095228 m occurring in the 6th step, while the y direction of the maximum base shear force is 555.339 tons and displacement of 0.152807 m occurs in the 14th step. The performance point value is also obtained from the analysis pushover in the x direction with = 475.025 tons and D = 0.087 m yield Sa = 0.205 g and Sd = 0.072 m, while for the y direction with = 499.168 tons and D = 0.086 m yield Sa= 0.225 g and Sd = 0.067 m. Then at the level of building performance in the x and y direction parametersMaximum Total Drift Ratio included in the category Immediate Occupancy (IO), it can be concluded that the building did not suffer significant damage, the building is safe when an earthquake occurs, the risk of loss of life and structural failure is not too significant and can be used again immediately.

Abstract

Rust on steel is often a problem in construction work. Rust occurs when iron oxidizes. The cause is prolonged exposure to water, air, or an acidic environment. Iron will bind oxygen atoms in the air to form iron oxide/rust. Rust continues to increase, accelerating the process of damage to buildings. Rust cannot be avoided, but it can control its rate. St.37 carbon steel is the most widely used material for various types of building construction. Therefore, it is necessary to carry out experimental tests regarding the rate of corrosion and its effect on the strength of steel. In this research, using St.37 steel plates, the corrosion process was carried out by leaving the specimens in an open space, immersing the specimens in sea water, and immersing the specimens in fresh water for 15 days. The aim of this research is to analyze the corrosion rate and its effect on the strength of St.37 carbon steel material. Based on the research results, the average corrosion rate of test plates in open spaces was 0 MPy with an extraordinary resistance category; soaked in sea water 14.76 MPy with good category; and soaked in fresh water 39.37 MPy with the fair category. Meanwhile, based on the tensile test results, the average strength was 560.8 MPa for objects, 510.4 MPa, and 492.8 MPa, respectively. This corrosion rate affects the strength of the steel, the greater the corrosion rate, the tensile strength of the steel plate decreases.

Abstract

Augmented Reality (AR) technology is a technology that helps visualize objects in a more real form (3 dimensions). The concept of AR technology is not only applied to games but can also be applied to the field of education to provide understanding and learning motivation for students. The problem that occurs in elementary school students is the lack of interest and motivation to learn mathematics, especially about geometric figures, which has an impact on reducing the final mathematics score. It is hoped that the implementation of training in making AR and learning videos can be used by teachers to provide learning innovation and increase student motivation. Community service activities are carried out in the Megaluh District elementary school teacher working group, totaling 17 elementary schools. The final results of this PKM activity received a positive response from the training participants, with a satisfaction level of above 70%, and they hope that activities like this can be carried out regularly to provide knowledge updates in the field of technology for education.
