"[ABSTRAK
Lapangan AAA merupakan lapangan gas yang terdapat pada lingkungan Delta
Mahakam, Cekungan Kutai, Kalimantan Timur. Lapangan AAA merupakan bagian
dari lapangan gas dengan produksi terbesar di Indonesia yang telah dieksplorasi dan
diproduksi lebih dari 40 tahun. Salah satu tahapan penting setelah proses eksplorasi
adalah mengaplikasikan metode karakterisasi reservoar untuk pengembangan
lapangan. Karakterisasi reservoar dalam penentuan distribusi lithologi dan fluida
sangat penting dilakukan untuk mengetahui daerah berprospek ekonomis yang belum
ditembus oleh sumur produksi.
Pada penelitian ini karakterisasi reservoar yang digunakan adalah metode Analisa
AVO dan Extended Elastic Impedance (EEI). Analisis AVO mengunakan data prestack
3D gather dan bantuan velocity cube. Data DTS yang digunakan pada penelitian
ini terdapat pada sumur 3A45, 3A50, dan 3A45. Metode Extended Elastic Impedance
(EEI) dimulai dengan penentuan sudut Chi (X) pada nilai koeffisien korelasi yang
maksimum (mendekati nilai 1) dan analisis crossplot untuk menentukan nilai cut-off
indikator lithologi dan indikator fluida pada setiap parameter fisika dari data sumur.
Hasil analisis menyebutkan bahwa fluida pada daerah penelitian merupakan AVO
kelas III. Indikator lihtologi (reservoar dan non reservoar) dapat dipisahkan dengan
parameter Gamma Ray (reservoar bernilai 20 – 60 GAPI) dan Density (reservoar
bernilai 1.75 – 2.17 g/cc). Sedangkan indikator fluida (gas dan water) dapat
dipisahkan dengan parameter Lambda-Rho (gas bernilai 1.5 – 9 Gpa*g/cc), Lambda
per Mu (gas bernilai 0.5 – 2.5), Vp per Vs (gas bernilai 1.5 – 2.2), dan Poisson Ratio
(gas bernilai 0.16 – 0.35). Hasil inversi Extended Elastic Impedance (EEI) pada GTS
3A menyebutkan bahwa inversi Lambda-Rho mempunyai akurasi 78.57% (MFA) dan
85.71% (MFB), inversi Lambda per Mu mempunyai akurasi 50% (MFA) dan 85.71%
(MFB), inversi Vp per Vs mempunyai akurasi 71.42% (MFA) dan 71.42% (MFB),
Inversi Poisson Ratio mempunyai akurasi sebesar 71.42% (MFA) dan 78.57% (MFB).

ABSTRACT
AAA field is a gas field that located in Delta Mahakam environment, Kutei Basin,
East Kalimantan. AAA field is a part of giant gas field which has biggest production
in Indonesia already explored and produced almost over 40 years. One of important
steps after exploration of the field is to conduct a reservoir characterization for field
development. Reservoir characterization to determine lithology distribution and fluid
content is very important to know the prospect area which has economical values and
not penetrated yet by infill wells or production wells.
Reservoir characterization method that has been used in this study are AVO analysis
and Extended Elastic Impedance (EEI). Pre-stack 3D gather data and velocity cube
used for AVO analysis in this study. DTS logs only available in 3A45, 3A50, and
3A55. Extended Elastic Impedance method started with determination of Chi (X)
angle that has maximum correlation coefficient (near to 1 value) and cross-plot
analysis to determine cut-off value for lithology indicator and fluid indicator in each
well data parameter.
Analysis results show that fluid class in this study is AVO class III. Lithology
indicator (reservoir and non reservoir) can be separated by Gamma Ray (value of
reservoir between 20 – 60 GAPI) and Density (value of reservoir is between 1.75 –
2.17 g/cc). Fluid indicator (gas and water) can be separated by Lambda-Rho (value
of gas is between 1.5 – 9 Gpa*g/cc), Lambda per Mu (value of gas is between 0.5 –
2.5), Vp per Vs (value of gas is between 1.5 – 2.2), and Poisson Ratio (value of gas is
between 0.16 – 0.35). Results of Extended Elastic Impedance inversion in GTS 3A
show that Lambda-Rho inversion has 78.57% accuracy (in MFA) and 85.71%
accuracy (in MFB), Lambda per Mu inversion has 50% accuracy (in MFA) and
85.71% accuracy (in MFB), Vp per Vs inversion has 71.42% accuracy (in MFA) and
71.42% (in MFB), Poisson Ration has 71.42% accuracy (in MFA) and 78.57%

"Lokasi jembatan pada daerah rawan gempa dan penurunan mutu beton secara signifikan menyebabkan perlunya studi lebih mendetail mengenai perilaku inelastik pier jembatan tersebut. Perilaku inelastik jembatan dapat diidentifikasi melalui analisa nonlinear time history pada sendi plastis yang terjadi pada kolom pier. Untuk mendapatkan perbandingan perilaku sendi plastis, maka pier dimodelkan menjadi dua, yaitu model desain (mutu rencana) dan model eksisting (mutu rendah). Kondisi akhir penampang pasca eksitasi gempa dapat diketahui dengan menggunakan elemen fiber pada program MIDAS CIVIL. Hasil simulasi yang dilakukan menunjukkan bahwa hampir semua penampang model eksisting mengalami crushing beton, sementara penampang model desain hanya mengalami cracking. Selain itu, juga terjadi perubahan tipe kegagalan struktur dari kegagalan daktail pada model desain menjadi kegagalan getas pada model eksisting.

Bridge located at seismic zone and the concrete strength deterioration lead to a more detailed investigation of the inelastic behaviour of the bridge. The inelastic behaviour can be identified by nonlinear time history analysis on the plastic hinge, which occur at the column. For results comparation, two models are used for the pier which are deign model (initial design compressive strength) and existing model (low compressive strength). Final condition of the column section after lateral excitation can be obtained by assigning fiber element on MIDAS CIVIL. Simulation results show that concrete crushing occur at the existing model section overall, while on design model section only concrete cracking exist. Furthermore, change of failure mode develops from ductile failure (design model) to brittle failure (existing model)."

"ABSTRACT
One of the simple models to address quantum many body effects in materials with impurities is Anderson Impurity Model. It describes a system consisting of non interacting conduction electrons having hybridization with a localized orbital with strong electron electron interaction at a particular site. This model has been proven successful to explain the phenomenon of metal insulator transition through Anderson localization. Despite the well understood behaviors of the model, little has been explored theoretically on how the model properties gradually evolve as functions of hybridization parameter, impurity concentration, and temperature. Here, we propose to do a theoretical study on those aspects of a single impurity Anderson model using the distributional exact diagonalization method. We solve the model Hamiltonian by randomly generating sampling distribution of a few energy levels of conduction electrons with various number of occupying electrons, starting from zero to the maximum number allowed by the available single orbital states. The resulting energy eigenvalues and eigenstates are then used to define the local single particle Green function for each sampled electron energy distribution using Lehmann representation. Later, we extract the corresponding self energy of each distribution, then average over all the distributions to obtain the final self energy of the system and construct the local Green function of the system to calculate the density of states. We repeat this procedure for various values of hybridization parameters, impurity concentrations, and temperatures. We discuss our results in connection with the criteria of the occurrence of metal insulator transition in this system.

ABSTRACT
Salah satu model sederhana yang menunjukkan efek kuantum sistem banyak partikel pada material yang memiliki impuritas adalah Anderson Impurity Model. Model tersebut mendeskripsikan sebuah sistem yang memiliki elektron konduksi yang tidak saling berinteraksi namun mengalami hibridisasi dengan orbital yang terlokalisasi, dimana terjadi interaksi yang cukup kuat antar elektron pada orbital tersebut. Model ini terbukti berhasil menjelaskan fenomena metal-insulator transition melalui Anderson localization. Meskipun secara umum model ini telah dipahami, masih sedikit penjelasan teoretis terkait bagaimana model impuritas ini bergantung terhadap parameter hibridisasi, konsentrasi impuritas, dan suhu. Pada penelitian ini, kami mengusulkan studi teoretik mengenai pengaruh aspek-aspek tersebut terhadap single impurity Anderson model dengan menggunakan metode distributional exact diagonalization. Kami mengkontruksi Hamiltonian model ini dengan distribusi energi elektron konduksi yang acak dengan berbagai variasi jumlah elektron yang mengisi orbital sistem, berawal dari kondisi orbital kosong tidak terisi elektron sama sekali sampai jumlah maksimum yang diperbolehkan. Eigenvalue dan eigenvector yang dihasilkan dari setiap sampling digunakan untuk mendefinisikan fungsi Green orbital impuritas melalui Lehmann representation. Kemudian kami mengekstrak self-energy untuk setiap distribusi dan merata-ratakannya. Self-energy rata-rata yang diperoleh inilah yang diperlukan untuk mengkonstruksi fungsi Green total bagi elektron konduksi maupun elektron impuritas, dimana masing-masing fungsi Green tersebut digunakan untuk menghitung densitas keadaan. Kami mengulangi prosedur ini untuk berbagai variasi nilai parameter hibridisasi, konsentrasi impuritas, dan suhu. Diskusi terkait hasil penelitian yang diperoleh mengacu pada kriteria terjadinya fenomena metal-insulator transition pada sistem ini."
