    In this study we utilise a non-parametric, slacks-based model (SBM) approach to analyse efficiency and productivity changes for Indonesian banks over the period January 2006 to July 2007. Efficiency scores and Malmquist productivity indices are estimated using the approach for efficiency and super-efficiency estimation suggested by Tone (2001, 2002). Additionally, the Malmquist indices are decomposed into technical efficiency change and technological shift components. Using monthly supervisory data provided by Bank Indonesia we find that, under the intermediation approach to efficiency estimation, average bank efficiency was reasonably stable during the sample period, ranging between 70% and 82%, with 92 of the 130 banks in existence at that time having efficiency scores of over 70%, including 10 with (super)efficiency scores above unity. We also find that technical efficiencies under the Intermediation approach to describing the banking production process are relatively stable. Malmquist results for the industry suggest that the main driver of productivity growth is technological progress. A strategy based on the gradual adoption of newer technology, according to our results, thus seems to have the highest potential for boosting the productivity of the financial intermediary operations of Indonesian banks.Indonesian Finance and Banking; Productivity; Efficiency.

    Historically, boarding schools (pesantren) since its inception has never silent in face of religious social problems. Activities pesantren in response to global problems has been demonstrated since the early days of glory. Involvement of schools in globalized world has been proved by historical facts are not possible to be denied. Pesantren with various elements of education has been able to develop character education to be maximal. This is reflected in planting of theoretical value obtained from studies book in form of real practices in daily life. Habit can form a good character to students, and process naturally without forced. Success of schools in shaping character invites many other institutions to emulate design of schools, ie educational boarding. Many education experts believe that concept of a boarding education such as that implemented by schools actually capable of shaping students' character

    Reflection and transmission of guided ultrasonic plate waves by vertical stiffeners

    Ultrasonic guided waves are very useful for structural health monitoring. They have the potential to interrogate and detect damage in a structure over a large area with few transducers. Guided plate modes (Lamb waves) are used and proposed for damage detection at a distance in semi-monococque structures such as airplane fuselages and spacecraft structures. The interaction of guided plate waves with stiffening members such as ribs, stringers, or the integral stiffeners used in spacecraft structures limits the distance over which structural health monitoring non-destructive evaluation systems can detect damage. This paper develops a simple explanatory model for the scattering of low-order ultrasonic Lamb waves crossing a stiffening device. The model illuminates the underlying mechanics of waves crossing a stiffener. The model shows that stop-bands for transmission of S0 (longitudinal pressure) waves across a stiffener line up with flexural resonances of the stiffener. It also demonstrates why transmission of A0 (flexural) waves is more complicated and harder to predict. The model is shown to agree well with both boundary element method calculations and experimental measurements.This article may be downloaded for personal use only.

Maka dari itu diperlukan evaluasi terhadap kinerja dan performa pembangkit yang ada saat ini. Untuk itu, teknologi ultra-supercritical (USC) sangat dibutuhkan dimana efisiensi yang didapatkan oleh teknologi ultrasupercritical mendekati 48% ,dimana pembangkit yang ada saat ini, subcritical power plant, memiliki efisiensi hanya berkisar 38%. Dan juga batubara yang paling banyak digunakan saat ini adalah batubara kualitas tinggi dan medium, dimana ketersediaan saat ini khususnya di Indonesia, mulai menipis. Maka dari itu, batubara kualitas rendah dipilih untuk menjadi bahan bakar pada penelitian kali ini. Dimana batubara kualitas rendah memiliki ketersediaan yang sangat banyak juga harga yang murah dibanding kualitas tinggi dan medium(sedang). Penelitian dilakukan dengan cara membuat pemodelan dengan menggunakan perangkat lunak cycle-tempo. Dimana variasi yang digunakan adalah variasi nilai kalor (LHV) pada batubara berkualitas rendah (low rank coal) untuk mengetahui jumlah bahan bakar yang digunakan dan juga biaya operasi pada pembangkit dengan ultrasupercritical technology (UST). Variasi dari penelitian ini adalah nilai LHV pada 3800, 4000, 4200, dan pembebanan 50%, 75%,100%, dan 110%.

František Knapp, Ph.D., Institute of Particle and Nuclear Physics Abstract: Since the nucleus is a quantum many-body system consisting of con- stituents whose mutual interaction is not satisfactorily known, it is necessary to use approximate methods when describing the nucleus. Basic approximate approaches in the microscopic theory of the nucleus are the Hartree-Fock the- ory, Tamm-Dancoff approximation and random phase approximation. They are described in the first chapter of this thesis. The main aim was to develop mi- croscopic models for open-shell nuclei with two valence particles or holes. They are described in the second chapter, which contains detailed derivations of the relevant formulae. These methods have been numerically implemented. The re- sults of the calculations of the nuclear spectra and the electromagnetic transition probabilities are presented in the third chapter.

    Abstract: "Kebo-keboan" tradition has been widely discussed in various journals nowadays. But no one has studied the gospel bridge from Christian apocalyptic literature with "kebo-keboan" tradition. The author asked, can the apocalyptic concept in Revelation 22:1-5 be a gospel bridge for the “kebo-keboan†tradition? The author uses Paul Hiebert's critical contextualization concept as a research methodology. This methodological procedure consist of cultural analysis, Bible analysis, critical responses, and making new contextualization practices. From the cultural and Bible analysis, the author compares the vision receiver, apocalyptic environment, vision, and trancendent person. The author gives two critical response. The trancendent person replaced by God and the Lamb. The vision receiver, apocalyptic environment, and the Using community’s vision is acceptable. The author proposes three things for the new contextualization practice. The sowing seeds practice can be seen as a consumnation from God through tree and water of life. Offerings can be interpreted as an expression of gratitude for God as He lifted the curse. Then the dependence and eminence of Dewi Sri are diverted to God. In conclusion, the writer proves that the apocalyptic concept in Revelation 22:1-5 can be a gospel bridge for the “kebo-keboan†tradition. Keywords: Revelation 22:1-5, apocalyptic, kebo-keboan tradition, and critical contextualization Abstrak: Tradisi “kebo-keboan†ramai diperbincangkan dalam banyak jurnal kekinian. Namun belum ada yang mengkaji jembatan injil dari literatur apokaliptik Kristen dengan tradisi “kebo-keboanâ€. Penulis bertanya, apakah konsep apokaliptik dalam Wahyu 22:1-5 dapat menjadi jembatan injil bagi tradisi “kebo-keboanâ€? Penulis memakai konsep kontekstualisasi kritis Paul Hiebert sebagai metodologi penelitian. Prosedur metodologi ini yaitu analisa kultur, analisa Alkitab, memberi respons kritis, serta membuat praktik kontekstualisasi baru. Dari analisa kultur dan Alkitab, penulis membandingkan sosok pahlawan yang menerima visi, lingkungan apokaliptik, visi yang diterima, dan pribadi transenden yang disembah. Penulis memberikan dua respon kritis. Respons pertama adalah pribadi transenden yang dipercayai masyarakat Using perlu diganti dengan Allah dan Anak Domba. Respons kedua adalah sosok pahlawan, lingkungan apokaliptik, dan visi yang diterima masyarakat Using dapat diterima. Penulis mengusulkan tiga hal dalam praktik yang diperbaharui. Penyemaian bibit dapat dilihat sebagai pemulihan Allah melalui pohon dan air kehidupan. Sesaji dapat dimaknai sebagai ungkapan syukur atas kutukan yang telah diangkat oleh Tuhan. Lalu kebergantungan dan keutamaan dari Dewi Sri dialihkan kepada Allah. Pada akhirnya penulis membuktikan bahwa konsep apokaliptik dalam Wahyu 22:1-5 dapat menjadi jembatan injil bagi tradisi kebo-keboan. Kata Kunci: Wahyu 22:1-5, apokaliptik, tradisi kebo-keboan, kontekstualisasi kritisÂ
