    Wireless communication applications in the future require high data rate and efficient spectrum services. To be able to provide a high bit rate we can use plural modulation or multicarrier. The use of FBMC OQAM modulation aims to provide increased performance compared to the previous modulation, namely OFDM, this is due to the use of FBMC with its orthogonality properties and the use of OQAM which has a stronger advantage over the dispersion effect and has a high data rate. To get the information signal issued, ZF (Zero Forcing) equalization is used. Simulation results show that FBMC OQAM with ZF can reduce BER from 0.4275 at SNR 0 dB to 0.01231 at SNR 25 dB. Whereas the OQAM without ZF FBMC has a BER value of 0.513 at SNR 0 dB to 0.5212 at SNR 25 dB. This shows that the FBMC OQAM using ZF has a lower BER value than the FBMC OQAM without ZF.  Keywords : FBMC, OQAM, ZF, SNR, BER Abstrak Aplikasi komunikasi nirkabel di masa depan menuntut pelayanan data rate yang tinggi dan spektrum yang efisien. Untuk dapat menyediakan laju bit yang tinggi dapat menggunakan modulasi jamak atau multicarrier. Penggunaan modulasi FBMC OQAM bertujuan memberikan peningkatan unjukkerja dibandingkan dengan modulasi sebelumnya yakni OFDM, hal ini karena penggunaan FBMC dengan sifat orthogonalitasnya dan penggunaan OQAM yang memiliki keunggulan lebih kuat terhadap efek dispersi serta memiliki kecepatan data yang tinggi. Untuk mendapatkan sinyal informasi yang dikirimkan, digunakan ekualisasi ZF (Zero Forcing). Hasil simulasi menunjukkan FBMC OQAM dengan ZF dapat menurunkan BER dari nilai 0,4275 pada SNR 0 dB menjadi 0,01231 pada SNR 25 dB. Sedangkan pada FBMC OQAM tanpa ZF memiliki nilai BER 0,513 pada SNR 0 dB menjadi 0,5212 pada SNR 25 dB. Hal ini menunjukkan bahwa FBMC OQAM menggunakan ZF mempunyai nilai BER yang lebih rendah dibandingkan FBMC OQAM tanpa ZF.  Kata Kunci : FBMC, OQAM, ZF, SNR, BER

    Grand Heaven Sidoarjo is the largest funeral home in East Java which has 2 buildings, namely the Grand Heaven Main Building and the Grand Heaven Office Building. The author will make modifications by adding a cantilever to the Grand Heaven Main Building which functions as the office of the Grand Heaven itself, so that the Grand Heaven Office Building can be converted into a parking lot. The material used in this building structure is reinforced concrete and structural elements that will be modified using a composite column structure on the exterior column and steel cantilever. The purpose of this study is to determine the behavior of the building structure with the addition of a cantilever. This study will use the Capacity Spectrum Method (CSM) as a method of structural planning and then carry out non-linear pushover static analysis to determine the pattern of collapse and behavior of the building structure during an earthquake. The auxiliary program used is ETABS as a structural model. The results of this study have an Immediate Occupancy (IO) performance. The resulting structural components are able to achieve structural stability with the largest beam dimensions used measuring 350x650 mm, concrete columns of 700x700 mm, steel beams with a WF profile of 500.300.11.18 and a kingcross composite column with a profile of 600.300.12.20 with concrete dimensions of 700x700 mm. The beam-column connection on the cantilever has met the strong column-weak beam requirements by using the extended end-plate rigid type connection.
