Abstract
Penelitian ini membahas tentang mitigasi tsunami yang
disebabkan oleh gempa bumi di kepulauan Jepang. Jepang
merupakan salah satu wilayah yang memiliki seismisitas tinggi
akibat adanya 4 lempeng aktif dunia yang saling menumbuk.
Tahun 2011, tsunami dasyat terjadi di Jepang sehingga penelitian
tentang prediksi tsunami menggunakan program Joko Tingkir
perlu dilakukan guna mitigasi bencana tsunami. Program Joko
Tingkir mampu mengestimasi dengan cepat nilai durasi rupture,
periode dominan dan periode lebih dari 50 detik dan
perkaliannya untuk menentukan apakah gempa bumi tersebut
memicu tsunami atau tidak. Hasil penelitian pada 120 event
gempa yang terjadi pada tahun 2011-2016, termasuk gempa bumi
yang menimbulkan tsunami Tohoku-Oki, didapatkan kesimpulan
nilai parameter-parameter rupture gempa bumi di Jepang pada
tahun 2011-2016, yaitu; Durasi rupture (Tdur): 2.9 – 200,
Periode Dominan: 2.9 – 70.02, T50 Exceeendance: 0.49 – 55, Td
* T50Ex: 0.085 – 929.513, Tdur * T50Ex: 0.0214 – 11825.2 dan
keakuratan program joko tingkir mencapai 96.15% terhadap data

=================================================================================================The research studies about tsunami prediction which
caused by earthquake in Japanese archipelago. Japan has
high seismicity because 4 world active plates crash each other
and in the 2011, mega tsunami occurred in japan. So, the
research about tsunami prediction by using Joko Tingkir
program is very needed to be done for tsunami hazard
mitigation. Joko Tingkir program can estimate rapidly the
value of rupture duration, dominant period, T50 Exceedance
and it’s multiple. The parameter of rupture can give
information about tsunami generation which is caused by
earthquake more than magnitude of earthquake. After
studying 52 earthquakes in Japan since 2011 to 2016,
including the earthquake which generates tohoku-oki tsunami,
it concludes that the value of rupture parameters of the
earthquake is: Rupture Duration (Tdur): 2.9 – 200, dominant
period: 2.9 – 70.02, T50 Exceeendance: 0.49 – 55, Td *
T50Ex: 0.085 – 929.513, Tdur * T50Ex: 0.0214 – 11825.2
and the accuracy of Joko Tingkir program is 96.15% of
NOAA data
