Abstract

Geopolymer concrete is concrete composed of cystesis material of non-organic materials that go through a polymerization process so that it is environmentally friendly, so it can reduce the amount of carbon dioxide produced in Portland cement in the normal concrete manufacturing process which can cause a greenhouse effect. Geopolymer concrete requires a lot of silica and alumina. In geopolymer concrete, the most common alkaline activators used in geopolymer concrete are Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3). Fly Ash has a lot of silica and alumina and the role of alkali activator to dissolve the elements of silica and alumina. The method carried out is an experiment. This study used a ratio between fly ash and activator of 70%:30%, and used a ratio of activators between Na2SiO3 and NaOH of 5:2, 6:2, 7:2, 8:2, 9:2, with a cylinder test object of 20x10 cm with a test result of 42.71 MPa.Keywords: Activator, Compressive Strength, Geopolymer Concrete,

Abstract

The infrastucture of high-rise buildings must have an earthquake resistance. As a mitigation effort, a building must be symmetrical. When an earthquake occurs the response of the structure easily predictable. However, along with the development of architectural design, many buildings with irregular shapes (asymmetrical). So, it is necessary to analyze the behavior of structures in irregular buildings. The purpose of this study was to determined the maximum displacement value and a structural performance due to an earthquake loads based on ATC-40. The earthquake analysis used a Response Spectrum and Time History with the help of ETABS V17.0.1 software, case study located in Bekasi City Government Service Office (POLRES) building. The research used quantitative descriptive method. Based on the analysis, the maximum displacement value due to earthquake loads using the Response Spectrum analysis method for the X direction were 74,655 mm and 54,566 mm for the Y direction.Keywords: Asymmetrical, Displacement structure, Earthquake loads, Earthquake Resistance, Structure performance,

Abstract

The city of Bandung is one of the cities that is prone to earthquakes because it is passed by the Lembang fault. Therefore, buildings in the city of Bandung should have implemented the concept of earthquake-resistant buildings in their construction. To avoid the occurrence of damage or collapse of the structure of the building against an earthquake, it is necessary to analyze the building against the earthquake. This study aims to determine how many deviations occur in the building due to the earthquake and the performance of the building structure. The method used is the response spectrum and time history analysis method and then evaluates the performance of the structure against earthquakes using the ATC-40 standard. The building that is the case study is the Directorate of Drugs and the Directorate of Intelligence and Security for the West Java Police, which consists of 5 floors. Structural modeling and analysis were performed using ETABS v20. Earthquake records used are Imperial Valley, Kobe and Trinidad earthquakes. Based on the results of the analysis of the maximum deviation with the response spectrum method 26.74 mm in the X direction and 26.46 mm in the Y direction. Meanwhile, for the time history analysis, it was obtained 33.05 mm in the X direction and 28.96 in the Y direction. The maximum value of the total deviation obtained 0.0016 m and the maximum value of inelastic deviation obtained 0.0014 m so that it shows the level of performance of this building structure based on ATC-40 is Immediate Occupancy (IO), which means the structure is in a safe condition.Keywords : ATC-40, earthquake resistant buildings, spectrum response, time history,

Abstract

Abstrak: Saat ini permasalahan banyaknya pencari kerja adalah masalah yang sangat krusial terlebih setelah pandemik covid-19, masih banyak angka pengangguran di Indonesia. Kondisi ini menjadikan berbagai kegiatan pelatihan sangat diperlukan untuk meningkatkan kemampuan masyarakat termasuk kemampuan dari mahasiswa perguruan tinggi. Kemampuan menulis adalah salah satu kemampuan yang selain menjadi kemampuan khusus ilmiah juga dapat dikembangkan menjadi kegiatan yang menghasilkan nilai ekonomi atau uang, baik melalui penulisan buku, artikel surat kabar, novel, cerita pendek, puisi dan sebagainya. Pelatihan ini dilakukan terhadap mahasiswa Prodi Arsitektur 2021 dan mahasiswa Prodi Pendidikan Teknik Arsitektur 2020 yang kebetulan tengah mengambil mata kuliah yang diampu peneliti dan tim, seperti untuk mata kuliah Perumahan Permukiman, Perencanaan Bisnis Konstruksi dan Properti dan mata kuliah Kewirausahaan yang tengah membuat proposal Program Kreativitas Mahasiswa (PKM) dan paper paper kajian penelitian. Pelatihan dilakukan secara bertahap sebanyak 2 kali bersifat tambahan dari materi perkuliahan. Hasil yang didapat adalah mahasiswa mampu menghasilkan proposal proposal PKM yang lebih berkualitas  yang akan disubmit ke sistem DRPTM pada September 2023 dan mampu menghasilkan paper paper terpilih, dalam hal ini dipilih sebanyak 6 paper yang kemudian telah dibimbing lanjut untuk proses submit ke jurnal nasional. Kata kunci : Pelatihan Menulis, Mahasiswa Arsitektur, Kemampuan Wirausaha, Kemampuan Profesional Menulis
