ABSTRAKPerkembangan ilmu pengetahuan dalam bidang Geofisika pada umumnya
dan ilmu Seismologi pada khususnya tidak dapat lepas dari kemampuan alat ukur
yang diperlukan sehingga untuk menunjang kemajuan ilmu tersebut maka
perkembangan instrumentasi seismologi mutlak diperlukan, bahkan dalam hal ini
menjadi pemicu secara imbal balik dimana kemajuan dalam bidang instrumentasi
memicu kemajuan ilmu seismologi atau demikian sebaliknya.
Instrumentasi yang dibuat untuk mendeteksi getaran gempabumi telah
mengalami beberapa tahap perubahan dan perkembangan, dikenal dengan nama
seismograph, pada awalnya hanya dipakai untuk mencatat adanya getaran yang
timbul karena adanya gerakan ? gerakan dari lapisan bumi sedangkan bentuk
tampilannya sangat sederhana sebagai instrumentasi yang bersifat konvensional
dan analog, sedangkan TDS-303S merupakan instrumen yang merepresentasikan
perkembangan alat ukur modern berbasis digital dengan berbagai macam aplikasi
untuk penyajian data kegempaan ( Seismisitas ) dan pemroses data hingga
menghasilkan parameter-parameter gempabumi seperti magnitude, epicenter,
kedalaman gempabumi dan lain-lain .
Penggunaan seismograph TDS-303S dalam pengukuran seismisitas yang
dilakukan di Jogyakarta memberikan hasil yang dapat dipertanggung jawabkan
dimana hasil analisa data mengindikasikan lokasi yang sesuai dengan fakta di
lapangan yang merupakan jalur patahan sedangkan nilai rata-rata kesalahan adalah
0,5 yang menjadi nilai akurasi alat TDS-303S.
ABSTRACTThe development of Geophysics science particulary in the Seismology field
can not be separated from the ability of gauges that necessary to support the
advancement of the science of seismology . Instrumentation development is
absolutely necessary, even in this case, which lead to advances in the
advancement in the science of seismology or vice versa.
Instrumentation that designed to detect earthquake vibrations untill now
has undergone several stages of change and development. Instrumentation in
seismology that called seismograph, at the begining was used only to make
recording the movement of the earthsphere and the displayed in simply graph as
records while the appearence was very simple as the conventional
instrumentation and analog, while recently., TDS-303S is an instrument that
represents the development of modern measuring devices based on digital with a
wide range of applications for the presentation of seismic data (seismicity) and
processing datas to generate the earthquake parameters such as earthquake
magnitude, epicenter, depth of earthquakes and others. .
The use of TDS-303S seismograph in seismicity measurements conducted
in Yogyakarta provide results that can be justified where the location of the data
analysis indicated in accordance with the facts that the epicenters lied on the
fault line, while the average error is 0.5 that can be determined as the value of the
accuracy of the TDS -303S.;The development of Geophysics science particulary in the Seismology field
