"Indonesia terletak pada pertemuan lempeng tektonik aktif, jalur pegunungan aktif, sehingga menjadikan sebagian besar wilayahnya rawan terhadap bencana alam Gempa Bumi. Berdasarkan teori dan konsep manajemen bencana (disasters management) yang meliputi beberapa tahapan, yaitu: tahap tanggap darurat (response phase), tahap rekonstruksi dan rehabilitasi, tahap preventif dan mitigasi, dan tahap kesiapsiagaan (preparedness); maka upaya perencanaan sistem peringatan dini gempa bumi harus dipersiapkan dengan efisien untuk dapat mengurangi risiko yang diakibatkan. Dengan semakin berkembangnya teknologi informasi dan komunikasi berbasis Mobile phone, maka informasi dan komunikasi bukanlah suatu hal yang sulit terutama pada saat tanggap bencana. Dengan variabel-variabel yang diukur berupa media alat peringatan, prosedur penyelamatan diri, mobilisasi sumber daya dan pengetahuan menghadapi bencana gempa bumi. Variabel-variabel tersebut didapat dari studi literatur, kemudian setelah itu didapatkan faktor-faktor yang menyusun sistem peringatan dini (early warning system) gempa bumi yang akan ditambahkan ke dalam aplikasi. Setelah itu, survey dilakukan kepada masyarakat untuk mengetahui pengaruh tambahan fitur EWS (early warning system) bencana gempa bumi. Dari hasil survey yang telah diperoleh, dapat disimpulkan bahwa sebagian besar responden sangat setuju dengan persentase rata-rata dari semua pertanyaan di atas 50% bahwa adanya penambahan fitur earthquake early warning system dapat membuat masyarakat yang menggunakan aplikasi lebih waspada terhadap bencana gempa bumi.

Indonesia is located at the confluence of active tectonic plates, an active mountain route, thus making most of its territory prone to natural disasters from earthquakes. Based on the theory and concept of disaster management (disasters management) which includes several stages, namely: the response phase, the reconstruction and rehabilitation stage, the preventive and mitigation stage, and the preparedness stage; hence the effort to plan an earthquake early warning system must be prepared efficiently in order to reduce the resulting risks. With the development of mobile phone-based information and communication technology, information and communication is not a difficult matter, especially during disaster response. With the measured variables in the form of media warning tools, self-rescue procedures, mobilization of resources and knowledge of earthquake disasters. These variables are obtained from literature studies, then after that, the factors that compile an earthquake early warning system will be added to the application. After that, a survey was conducted to the public to determine the effect of the additional EWS (early warning system) feature of the earthquake. From the survey results that have been obtained, it can be concluded that the majority of respondents strongly agree with the average percentage of all questions above 50% that the addition of the earthquake early warning system feature can make people using the application more alert to earthquakes."

"Noise linier adalah energi seismik yang menjalar di sepanjang permukaan (gelombang permukaan). Karakteristik noise linier adalah frekuensi rendah, kecepatan rendah, dan amplitudo tinggi. Noise linier masih menjadi permasalahan dalam data seismik, sebab mampu menyamarkan sinyal refleksi. Teknik pengolahan yang saat ini digunakan adalah filter F-K, berpotensi untuk mereduksi sinyal refleksi yang berada pada rentang slope noise. Metode dekomposisi spektral berbasis transformasi wavelet merupakan metode filtering alternatif, mampu mendekomposisikan data seismik menjadi beberapa subband melalui filter low-pass dan filter high-pass. Setiap filtering mendekomposisikan data seismik ke dalam domain frekuensi (f) dan bilangan gelombang (k). Metode ini diujikan pada data real seismik darat 2-D yang memiliki rentang velocity 20 m/ms hingga 100 m/ms. Terdapat 2 metode filtering, yaitu membuang subband yang mengandung noise dan menggunakan filter F-K pada subband yang mengandung noise. Metode filtering 2 lebih efektif mereduksi noise linier pada data penelitian dibandingkan metode filtering 1. Hal ini dibuktikan pada hasil penelitian yang menunjukkan peningkatan kualitas tampilan shot point gather dan stacking.

Linear noise is seismic energy that propagates along the surface (surface waves). Characteristic of linear noise is low-frequency, low-velocity, and high amplitude. Linear noise is such a problem in land seismic data, because able to disguise signal reflection. Current processing techniques aimed at linear noise suppression, such as f-k filtering has potentially to reduce signal reflection which range in noise slope. A new alternative to f-k filtering is spectral decomposition based on wavelet transform, which decomposes seismic data into different sub bands by applying low-pass and high-pass filters. Each filtering decomposes the seismic data into frequency and wavenumber domain. This method is applied in real 2-D land seismic data to reduce linear noise with velocity range 20 m/ms to 100 m/ms. There are two methods of filtering, killing sub bands which contained noise and using f-k filter on sub band which contained noise. Second method is more effective to reduce linear noise than first method. This technique leads to the improvement of shot records and final stack quality."

"Pada umumnya bangunan rumah toko (ruko) di Kota Medan tidak direncanakan secara baik dan dibangun dengan pengawasan yang buruk, sehingga beresiko besar terhadap beban dinamis gempa.Getaran gempa dari zona subduksi Sumatera yang mengandung frekwensi rendah dan berdurasi panjang dirasakan beberapa kali di Kota Medan.

AbstractIn Medan, the shop-house (ruko) buildings are generally not ngineered-designed properly and constructed in bad supervision; hence it has big risk to dynamic loads like earthquake. The low frequency and long duration of earthquake vibrations were felt frequently in Medan due to earthquakes in Sumatra subduction zones. Moreover, some houses and hotels have been cracked caused the tremor from Nias earthquake in 2005. Therefore, a number of samples of fresh concrete, either ready-mix or mixed manually, and the stick of steel reinforcement are taken from ruko construction site and tested in the lab. The results of the material compression and tensile testing are used as material properties of ruko model. The ruko model consists of 2, 3, and 4 stories and 1, 2, and 3 bays. The inelastic analysis of reinforced concrete structures are then applied by using IDARC2D program and employed synthetic ground motion forces from Nias subduction earthquake scenarios. The result shows that most of ruko buildings experiencing cracks extensively, even some of them show a high damage level with very low performance and beyond repair."
