Peta Respons Spektrum Provinsi Sumatera Barat untuk Perencanaan Bangunan Gedung Tahan Gempa
Full text linkAbstrak. Gempa aceh pada bulan Desember 2004 silam telah membuktikan zona sumber gempa subduksi Sumatera mampu menghasilkan magnitude Mw9,0 yang hampir setara dengan kejadian gempa pada zona subduksi di sekitar kepulauan Mentawai pada tahun 1883. Berdasarkan pertimbangan itu, dilakukan studi analisis hazard kegempaan pada wilayah Provinsi Sumatera Barat berdasarkan kriteria desain yang disyaratkan dalam SNI-1726-2002, yaitu untuk umur bangunan 50 tahun dan nilai kemungkinan terlampaui 10%. Analisa tersebut dilakukan berdasarkan teori probabilitas total dengan memanfaatkan perangkat lunak EQRISK yang dimodifikasi dan menggunakan pemodelan sumber gempa 2-D berdasarkan kajian seismotektonik dan identifikasi regional fault. Respons spektra desain di permukaan tanah diperkirakan berdasarkan faktor amplifikasi yang mengacu pada NEHRP 1997 berdasarkan spektra percepatan di batuan dasar untuk periode 0,2 detik dan 1,0 detik. Hasil akhir yang diperoleh adalah peta spektral percepatan pada lapisan batuan dasar di wilayah Provinsi Sumatera Barat dan respons spekra desain permukaan tanah dengan periode ulang 500 tahun.Abstract. The big earthquake event acted in Desember, 2004, shows that the subduction zone of the Sumatran trench is able to produce the magnitude 9,0 which is almost equal with the magnitude of the big earthquake event on Mentawai island in 1883. Therefore, a seismic hazard analysis was conducted on area of province West Sumatera to evaluate the significant code which develops based on SNI-1726-2002, that implements spectral hazard for 10 % probability of exceedance in building life time period of 50 years. The analyses were carried out using 2-D earthquake source model and the seismic hazard analysis software named EQRISK that is based on the total probability theorm. The design response spectrum on site ground surface are approximated by the amplification factor of NEHRP 1997 codes on spectral periods of 0,2 second and 1,0 second. The final result of this study are the spectral acceleration maps on the bedrock of province West Sumatera, and the design response spectrum on site ground surface for return period of 500 years
Digital Transformation in Archival Management: A Case Study of the PQX Study Program
Full text linkThe PQX Study Program is part of a State University in Indonesia, faces significant challenges in managing academic and administrative archives. Based on internal data until October, 2025, more than 6000 physical records are still managed manually or stored through online media such as Google Drive, without an integrated archiving system or adequate security mechanisms. This condition has resulted in delays in data retrieval, limited storage capacity, and increased operational costs due to the maintenance of physical archives. To address these issues, this study applies a software engineering approach using the System Development Life Cycle (SDLC) model to design a web-based archival information system prototype. The purpose of this research is to develop an integrated archival information system within the PQX Study Program. The research stages include user needs analysis, system design using a user-centered design approach, and prototype implementation. Data were collected through observation, and analysis of internal archival documents. The resulting digital archiving system design is expected to enhance document access efficiency, strengthen data security, and support the digital transformation of academic administration within the PQX Study Program
Studi Kehandalan Selubung Respons Spektrum Kelas Tanah Lunak Zona 5 Untuk Daerah Meukek, NAD
Full text link. Indonesia has been well known as one of the most seismically active countries in the world. Therefore, the building design in Indonesia should consider these seismic activities. Seismic hazard analysis for any site may develops based on SNI 03-1726-2002, that implements spectral hazard for 10 % probability of exceedance in a building life time period of 50 years. In this study, a site specific response spectra was conducted on Meukek site to evaluate the performance of the response spectra based on criteria on SNI 03-1726-2002 comparing the response spectra conducted by the big earthquake event off the west coast of northern Sumatra that acted recently. There is no available strong motion data for Meukek site that is representative at this moment, therefore the Deterministic Seismic Hazard Analysis is performed, and the synthetic time histories are then simulated based on a stochastic method using SMSIM program. The analysis of shear wave propagation is performed using NERA which is based on one dimensional wave propagation theorem. Dynamic soil properties are obtained from the correlation with N-SPT value from soil investigation report covering Meukek site. The final result of this research are the synthetic time histories on the bedrock, and the design response spectrum on the site ground surface based on design earthquake scenario
Deagregasi Hazard Kegempaan Provinsi Sumatera Barat
Full text link. Seismic hazard analysis for any site is performed based on SNI 03-1726-2002 implementing spectral hazard for 10% probability of exceedance in design time period of 50 year. Hazard deaggregation is required in seismic hazard analysis in order to determine the controlling magnitudes and distances for particular return periods of earthquakes. The values of these magnitude and distance give the information about a criteria of certain engineering decisions on predicting acceleration time history. The analysis was performed using the total probability theorm with 2D seismic source model. The final result of this study are deaggregation hazard maps of province West Sumatera for return period of 500 years
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
