ACKNOWLEDGEMENTS

I am extremely grateful to my supervisor, Professor Shinji Sato, who offered the most valuable guidance and continuous encouragement throughout the whole study. The constructive suggestions and helps from Professor Masahiko Isobe, Yoshimitsu Tajima and Yoshinobu Tsuji are also highly appreciated. I am indebted to my co-supervisor, Associate Professor Matsumoto, for providing me comments and suggestions in my research work.

I would like to express my appreciation to former Associate Researcher Takahide Honda for the helpful assistance and fruitful discussions on this study. Special thanks also to Mr. Takenori Shimozono for lots of help in MATLAB programming language. Thanks also to Associate Professor Guangwei Huang and Yukio Koibuchi.

Thanks and appreciation are also extended to laboratory’s secretaries, Miss. Hiroko Yamakami and Miss. Yoko Kodama as well as all members of Coastal Engineering Laboratory, for providing endless help and sharing a delightful and memorable life. Thanks to Mr. Junya Suzuki, my life tutors, for providing great assistances during my stay in Tokyo.

Appreciations to Foreign Student Officers: Ms. Nakamura and Ms. Hayashi for providing valuable information that facilitates my life in Japan. Thanks also to staffs of Faculty of Engineering (Reppin-kan) and Japanese Language Class teachers of the Department of Civil Engineering, who offered me the basic Japanese skills.

Finally, I wish to extend my sincere and special thanks to my parents and my girlfriend for their constant encouragement. With their spiritual support I overcame the difficulties both from study and life.

This study was supported by the Asian Development Bank-Japan Scholarship Program, which made my study in Japan possible.

Yuliarko's Master Thesis

This study is concerned with the development of a high-order numerical model to solve incompressible water wave motion based on improved nonlinear dispersive Boussinesq equations. A third-order Adams-Bashforth and a fourth-order Adams-Mouton predictor-corrector scheme was selected in an attempt to eliminate the truncation error terms that would be of the same form as the dispersive terms in the Boussinesq equations with second order schemes as in many other studies.

Eddy viscosity type momentum correction term was added into the Boussinesq equation to simulate the energy loss due to wave breaking and to extend the model application to surf zone wave transformation. The location of the breaking point was determined through a wave breaking criterion using the ratio of horizontal water particle velocity to wave celerity.

A moving boundary technique utilizing linear extrapolation is developed to investigate wave runup and rundown. Wave absorption at an open boundary was simulated by solving the Sommerfeld radiation and introducing sponge layer into the model.

Breaking regular wave runup propagation on a sloping beach is simulated. It would seem that inclusion of an accurate dissipation term becomes increasingly important with increasing degree of wave breaking. In regard to breaking regular wave runup simulation, additional dissipation term acted as bottom friction was required for long term stability in surf zone area. The validity of the model was confirmed by comparing computations with analytical solutions and measured data.

Perbedaan

Ketika perbedaan itu ada,
Disitulah kita harus belajar memahami..
Bersatu untuk mengerti,
Bukan saling diam tak bersuara..

Ego ini tidak bisa terima,
Karena berpendapat kita benar..
Timbul keputusan untuk berpisah,
Walau itu sangat menyakitkan..

Ternyata keputusan yang salah,
Karena tanpa pemikiran yg panjang..
Berpisah itu amat menyakitkan,
Maafkan aku kekasihku..

Cinta..
Kuharap kau selalu hadir,
Dalam suka maupun duka..
Saat ini dan sampai maut memisahkan kami..

Jangan pisahkan kami,
Dengan perbedaan yang ada..
Tuntunlah kami selalu,
Menjalani hari-hari untuk bersama selamanya..

Keyna Kisah Kasih Ku

ku berdiri di hempa tanpa tepi dengan keyakinanku..
kau selalu menemani hidupku dalam kesendirian..
aku dan nafasku selalu merindukanmu sampai tiba waktunya nanti..
kuteringat pada janjimu untuk keterikatan hanya untukmu..
pegang erat tanganku dan bimbing langkah kakiku..
arahku akan hilang tanpa hadirmu dalam gelapnya malam hariku..
siang dan malam yang berganti takan ada artinya jika kau tak ada
karena engkaulah sandaran hatiku..

Dan bila ku harus menantimu..
Takkan pernah lelah ku menanti..
Apakah salah diriku menantimu..
Karena kau kusayangi..

Takkan hilang cintaku ini..
Karena kau telah tinggalkan bekas di hatiku yang dalam..
Hingga tiada cinta yang tersisa di jiwa..
Melainkan hanyalah untukmu..

Duhai permaisuriku

engkau ratu di hariku

sesungguhnya

hati ini hanyalah untukmu

tiada lain selain kasihmu

bawa aku ke dalam duniamu
didalam nya kurasa hangatmu

mengalir engkau datang dengan angin tak terasa

engkau datang menghembus membelai muka
membasuh jiwa yang kering
mengisi hari penuh makna

tak pernah ku mengerti

betapa tulus cinta yang kau beri

menghelus hati menggores sukmaku

dan tak kan ku biarkan

kau pergi dariku

kuingin terbang bebas

bersama bintang-bintang di angkasa

taburkan sinar kemilau

dihening nya sepi malam

selalu berbagi rasa nuansa

larut dalam suasana

cinta

tutur katamu

bangkit kan gairahku tuk mencitaimu

hapuskan beban di jiwaku

luluh kan hatiku
jernihkan akal sehatku

engkau adalah sejuta alasan

mengapa duniaku

ada dan nyata

I love you It seems a waste To reminisce about you Because I want to keep you mine and mine alone I don't really wanna remember you I mean, it's embarassing Grinning to myself Eventhough you were late coming home Tired from a late night You picked me up in your arms Even in my dreams, I knew it I miss you so I couldn't feel anymore helpless I miss you so I'll always love you Did you know, What I wished for that night when we went for a drive? Did you know That I saw our happiness In the sky we looked up at together? You took this one 'me' laying there Made her beautiful and were always there for me I miss you so I don't wanna be any further away from you I miss you so I'll always love you I miss you so I couldn't feel anymore helpless I miss you so I'll always love you I will always, always and forever I will always love you.
