Indonesia is an area prone to earthquakes. Earthquakes caused by the movement of the earth's plates are the biggest cause of earthquakes that will cause damage to the building structure. Earthquakes occurring in Indonesia often cost lives. However, it is certain that the cause of the loss of life is not directly caused by the earthquake, but caused by the destruction of the building that caused the collapse in the building.The purpose of writing the research is to determine the performance criteria of the university building's seismic performance from the performance point value using the ATC-40 code, showing the melamine scheme (plastic joint distribution) occurring from the calculation of the software program, knowing the collapse pattern of the building so it can be known the joints Suffered damage and suffered destruction of pushover analysis.From the results of the study, the structure of the building is able to provide nonlinear behavior indicated by the initial phase and the majority of plastic joints occur in new beam elements and then column elements. The performance level of the structure enters the criterion of operational which means that minor structural and building damage can be reused immediately.

Indonesia is one of the countries in the earthquake region. Therefore, it is necessary to build earthquake-resistant buildings to reduce the risk of material and life losses. Reinforced Concrete (RC) shear walls is one of effective structure element to resist earthquake forces. Applying RC shear wall can effectively reduce the displacement and story-drift of the structure. This research aims to study the effect of shear wall location in symmetric medium-rise building due to seismic loading. The symmetric medium rise-building is analyzed for earthquake force by considering two types of structural system. i.e. Frame system and Dual system. First model is open frame structural system and other three models are dual type structural system. The frame with shear walls at core and centrally placed at exterior frames showed significant reduction more than 80% lateral displacement at the top of structure.

Piezoelectric adalah suatu bahan yang apabila terkena tekanan mekanik akan menghasilkan medan listik. Bahan piezoelectric juga bersifat reversible dimana jika medan listrik diterapkan pada bahan piezoelectric, maka pada bahan tersebut terjadi deformasi mekanik. Karena kelebihan material ini, maka bahan piezoelectric ini mulai banyak digunakan sebagai bahan untuk membuat sebuah sistem yang dapat melakukan energy harvesting. Sistem ini dapat menghasilkan energi listrik dengan menangkap tekanan atau getaran yang datang dari luar. Pada umumnya bahan piezoelectric yang ada di pasaran berbentuk lingkaran (piezoelectric disk) dengan diameter yang berbeda-beda. Penelitian ini menguji piezoelectric disk ini dengan uji tekanan dan uji getaran untuk melihat pengaruh luas permukaan piezoelctric disk ini terhadap perfomanya dalam menghasilkan energi listrik. Piezoelectric disk yang digunakan pada penelitian ini memiliki diameter sebesar 12 mm, 15 mm, 20 mm, dan 35 mm. Hasil pengujian didapatkan bahwa piezoelectric disk dengan diameter 35 mm menghasilkan rata-rata tegangan listrik paling tinggi. Dari sini dapat disimpulkan bahwa tegangan yang dihasilkan oleh piezoelectric disk berbanding lurus dengan luas permukaan piezoelectric disk tersebut.Kata kunci : Getaran, Luas Permukaan, Piezoelectric, Tekanan.

The concept of earthquake-resistant buildings is very meaningful to try on buildings located in certain earthquake areas, especially in Indonesia considering the situation which is located in a shock area with a fairly high intensity of events. The purpose of this research is to determine the seismic performance criteria of the planned structure using the SMRF (Special Moment Resisting Frame) structural system from the results of the displacement values using the ATC-40 code, showing the yielding scheme (plastic joint distribution) that occurs from the calculation results of the software program, knowing the pattern of building collapse so that it can be known joint- joint that is damaged and damaged from the pushover analysis. From the results of the research, the building structure is able to provide nonlinear behavior which is indicated by the initial phase and the majority of the occurrence of plastic joints occurs in new beam elements and then column elements and has fulfilled the earthquake-resistant building concept, namely strong column - weak beam. The results of the structural performance evaluation according to the ATC-40 rule that the Performance Level of the SMRF building in the x and y directions is at a Performance Level of 0.011 in the Immediate Occupancy (IO) category where the building is safe during an earthquake, the risk of loss of life and structural failure is not too significant, the building does not experience significant damage, and can be reused and not disturbed by repair problems, where the strength and stiffness are approximately the same as the conditions before the earthquake.

Earthquakes that often occur in Indonesia are tectonic earthquakes. Indonesia is one of the countries in the earthquake area. Thus, the construction of structures built in earthquake-prone areas must meet applicable national standards and the structures can still function and be safe from earthquakes affected by the earthquake. Reinforced concrete shear walls are one of the structural elements that effectively resist earthquake forces. The application of reinforced concrete shear walls can effectively reduce the displacement and shear forces of the structure floor. This study aims to determine the effect of shear wall position on symmetrical high-rise buildings due to earthquake loads. In this research, the building that is analyzed is earthquake by considering two types of structural systems. Namely the frame system and the dual system. The first model is an open frame structure system, and the other three models are a double type structure system. The dual system with shear walls in the core and placed in the center of the building showed a significant reduction of more than 85% of lateral displacement at the top of the structure

Tegangan yang dibaca oleh Arduino Mega akan ditampilkan menggunakan TFT LCD. Pengujian dilakukan dengancara membiarkan bahan piezoelectric terkena hujan dan angin. Hasil penelitian menunjukkan bahwa makin cepat angin bertiup dan makin tinggi curah hujan yang mengenai piezoelectric maka makin tinggi tegangan yang dihasilkan oleh bahan piezoelectric tersebut. Kata kunci: Arduino Mega, Pembangkit Listrik Tenaga Air Hujan, Piezoelectric, TFT LCD AbstractPiezoelectric material is one of material that if it exposed to mechanical pressure, it will produce electrical stress. Piezoelectric material is reversible which means that if an electrical voltage is applied to a piezoelectric material, then the material will occur mechanical deformation. Because of this reason, this piezoelectric can be used as material to create a system that can collect energy (energy harvesting). This research utilizes this piezoelectric material to make rainwater power plants. Raindrops will hit the piezoelectric material and produces the voltage where the voltage will be measured using a voltage sensor and Arduino Mega. The voltage which read by Arduino Mega will be displayed using the TFT LCD. Testing is done by leaving the piezoelectric material exposed to rain and wind. The results show that the faster the wind blows and the higher the rainfall that hits the piezoelectric, the higher the voltage produced by the piezoelectric material.

As has happened in various cases of earthquakes, the impact caused by each earthquake event varies, because the earthquake shaking that occurs on the ground is not only influenced by the distance and strength of the earthquake, but also by local soil conditions which are related to the amplification phenomenon. earthquake waves are influenced by the type and thickness of the soil/sediment layer above the bedrock. Reinforced concrete storey buildings are designed to withstand both vertical and horizontal loads. The taller the building, the greater the lateral load that will be received by the building structure. In the design of earthquake-resistant structures, the inelastic behavior of the structure is highly expected for the occurrence of earthquake energy dispersion during both moderate and strong earthquakes. In earthquake-prone countries such as Indonesia, it is required to comply with applicable national standards and the structure can still function and be safe from earthquakes affected by the earthquake. The purpose of this study was to determine how much influence the type of soil has on the lateral displacement of a 10-story reinforced concrete building using shear walls in accordance with earthquake building regulations (SNI 1726, 2019) and loading (SNI 1727, 2020). The results obtained that soft soil types have the largest displacement value with a value of 91,831 mm and hard rock soil types have the smallest displacement value with a value of 44,114 mm.
