The Paper presented at International Conference on Advance Science and Contemporary Engineering (ICASCE 2013) and published in journal of EPJ Web of Conferences (Springer) - Index in Scopus By Edy Irwansyah dan Edi Winarko Research conducted with the aim to develop spatial data cluster and analyse the characteristics of each cluster of data in order to develop spatial zonation of building damage hazard caused by the earthquake in the city of Banda Aceh. The data used consists of the data peak ground acceleration (PGA), lithology and topographic zone data with the four phases of the study consisted of data normalization with min-max method, determination of optimum data group with the connectivity index, Dunn index and the Silhouette index, clustering of data with the k -Means algorithm and the data interpolation using kriging algorithm to construct the zonation of hazard area. The optimum numbers of clusters used in these researches are two, with the first 170 data largely conce...

Paper in Int. Journal of Physic:Conference Series  Vol 423  012067 (IScopus)   doi:10.1088/1742-6596/423/1/012067 E Irwansyah , E Winarko 2 , Z E Rasjid  and R D Bekti The objective of this research is to develop seismic hazard area zones in the building infrastructure of the Banda Aceh City Indonesia using peak ground acceleration (PGA) measured using global and local attenuation function. PGA is calculated using attenuation function that describes the correlation between the local ground movement intensity the earthquake magnitude and the distance from the earthquake's epicentre. The data used comes from the earthquake damage catalogue available from the Indonesia meteorology, climatology and geophysics agency (BMKG) with range from year 1973 – 2011. The research methodology consists of six steps, which is developing the grid, calculation of the distance from the epicentre to the centroid of the grid, calculation of PGA values, developing the computer applica...

Presented in Seminar Nasional Informatika (SemnasIF) 2012, UPN "Veteran" Yogyakarta 20 Juni 2012 OLEH : EDY IRWANSYAH  dan EDI WINARKO   Penelitian ini bertujuan untuk menyusun zonasi daerah bahaya kegempaan pada infrastruktur bangunan di kota Banda Aceh menggunakan pendekatan nilai peak ground acceleration (PGA) dari fungsi atenuasi global dan lokal. PGA dihitung menggunakan fungsi antenuasi yang menggambarkan korelasi antara intensitas gerakan tanah setempat, magnitude gempa dan jarak dari sumber gempa. Data yang digunakan bersumber dari katalog gempa merusak badan meteorologi, klimatologi dan geofisika rentang tahun 1973 – 2011. Metode penelitian terdiri dari enam tahapan yaitu pembuatan grid, perhitungan jarak dari sumber gempa ke centroid grid, perhitungan nilai PGA, pengembangan aplikasi komputer, ploting nilai PGA di centroid grid,  dan penyusunan zona bahaya kegempaan dengan algoritma kriging . Kesimpulan penelitian  adalah bahwa fungsi atenuasi global y...

Paper in Journal Informatika Vol 11 No 1. 2012, PETRA University Surabaya ISSN : 1411-0105 BY : EDY IRWANSYAH, TRI BUANA SAPUTRA, LIM PIU, KRISNA WIRANGGA This Research conducted to develop geographic information system (GIS) that can be used to manage data and visualize the earthquake information. The research methodology consisted of collecting spatial data and non spatial data and system design. System design consists of designing the flow of data, designing databases, designing menus and design screens. The conclusion that can be drawn from this study is that GIS is developed to display information about how the earthquake that has been and is happening with magnitude parameters in a visual form suitable conditions. GIS is designed to use its own database and have the capacity to perform spatial data processing and non-spatial to generate a tsunami early warning system. This system can also simplify and accelerate the delivery of earthquake information to the public. Docum...

Presented in BINUS ICT Conference 2011- Jakarta 15 - 16th, August 2011 BY : EDY IRWANSYAH The Study to be conducted with the aimed to developing new methods for estimating tropical forest carbon stock using multi-resolution and multi-temporal satellite imagery with support vector machine (SVM) approach. To cover large area, a coarse resolution imagery of MODIS with seven band will be use as an input and high resolution imagery-QUICKBIRD for training data.  The main approach in the study will comprises four steps deriving forest cover vegetation (forest type and forest density) from QUICKBIRD imagery using clustering algorithm, constructing predictor variables derived from MODIS satellite imagery such as surface reflectance, normalized difference vegetation index (NDVI), normalized difference soil index (NDSI) and one ground-measured variable - shortwave radiation, Train the SVM  using predictor, apply extended domain of SVM for regression approximation and evaluate model p...
