Lokasi penelitian terletak di gedung Rusunawa (asrama mahasiswa) yang termasuk ke dalam wilayah administratif Universitas Jambi. Penelitian ini dilakukan untuk mengetahui nilai frekuensi alami tanah (f t ), bangunan b amplitudo (A 0 resonansi (%) dan indeks kerentanan (K) berdasarkan HVSR ( Horizontal to Vertikal Spectral Ratio ) FSR Floor ). Secara geologi, berada pada Formasi Muaraenim tersus...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

Context. Observations with the Hinode spectro-polarimeter have revealed strong horizontal internetwork magnetic fields in the quiet solar photosphere. Aims. We aim at interpreting the observations by means of results from numerical simulations. Methods. Radiative MHD simulations of dynamo action by near-surface convection are analyzed with respect to the relation between vertical and horizontal...

Abstract Microtremor is recorded with a device that very sensitive to subsurface soil vibrations, unwanted noise frequency waves are often also included. For this reason, processing needs be done using filters can attenuate the noise. In previous research, signal decomposition was performed Interpolated Finite Impulse Response (IFIR) filter and resulted attenuation at desired value. Using MATLA...

Silt liquefaction can occur due to the rapid cyclic loading of sediments. This result in loss bearing capacity underlying sediments and damage foundations infrastructure. Therefore, assessing hazards is an important aspect disaster prevention risk assessment geologically unstable areas. The purpose this study assess silt by using horizontal-to-vertical spectral ratio method. Single-station nois...
