"Tesis ini adalah kajian filosofis atas pengembangan komputasi DNA yang menggunakan analisis Arkeologi dan Genealogi dari Michel Foucault. Dalam penelitian ini, ditemukan adanya kesejajaran antara tiga episteme yang telah diungkap Foucault dengan tiga teknologi komputasi yang telah dikembangkan (penerapan metode Arkeologi) dan suatu jenis exercise atas kekuasaanpengetahuan sebagaimana diurai Foucault dengan titik tekan pada normalisasi, pengembangan model Artificial Intelligent Creatures, dan kemungkinan model panopticon molekuler (penerapan metode Genealogi). Hasil penelitian ini juga mengandaikan bahwa problem yang muncul harus disikapi dengan rumusan etika baru. Sebab, etika yang sudah dikembangkan tidak dapat mengatasi persoalan yang sekiranya dapat terjadi dengan dikembangkannya komputasi DNA.

This thesis is a philosophical study about DNA computation development which uses Genealogical and Archaeological analytics from Michel Foucault. In this thesis had been found parallelism between three episteme which described by Foucault with the three technology of computation (Archaeological applied) and a kind of exercise of knowledge-power as identified by Foucault which focusing in normalization, developing Artificial Intelligent Creatures, and possibility of molecular panopticon (Genealogical applied). This thesis supposes to formulate a new ethical approach. It is because the ethics which were developed not have an adequacy to solve a problematical discourse which comes from DNA computation development."

"Banyak model fenomena alam, aplikasi engineering, dan industri membutuhkan Sumber Daya Komputasi (SDK) yang tinggi untuk memroses data sehingga menghasilkan informasi yang dibutuhkan. Teknologi komputasi tingkat tinggi pun diperkenalkan banyak peneliti dengan diciptakannya Supercomputer beserta Operating System dan perangkatbantu (tools) pengembangnya seperti kompilator dan pustaka (library). Namun, mahalnya investasi SDK ini baik dalam pengadaan maupun pemeliharaannya memberatkan banyak pihak, sehingga diperlukan alternatif SDK yang tetap berkinerja tinggi tetapi murah. Untuk mengatasi keterbatasan tersebut, para peneliti telah membuat konsep alternatif, yakni konsep komputasi parallel pada jaringan komputer yang sudah ada. Banyak perangkatbantu diciptakan guna mengembangkan aplikasi dalam sistem SDK yang memanfaatkan mesin atau komputer dalam suatu jaringan, dimana masing-masing komputer ini berperan sebagai pemroses layaknya pemroses dalam sistem super computer.Tulisan ini akan mengkaji beberapa perangkat bantu yang cukup dominan di kalangan pemakai, yakni Parallel Virtual Machine (PVM), Message Passing Interface (MPI), Java Remote Method Invocation (RMI), serta Java Common Object Request Broker Architecture (CORBA) dan menyajikan eksperimen untuk mengetahui perangkatbantu mana yang paling cocok sehingga dapat pembantu calon user dalam memilihnya. Percobaan dilakukan pada SDK berbasis jaringan komputer pribadi (Personal Computer) dan menghasilkan percepatan yang cukup berarti. Dari keempat perangkatbantu tersebut masing-masing teridentifikasi cocok untuk pengembangan pada kondisi tertentu.

A Study on Parallel Computation Tools on Networked PCs. Many models for natural phenomena, engineering applications and industries need powerfull computing resources to solve their problems. High Performance Computing resources were introduced by many researchers. This comes in the form of Supercomputers and with operating systems and tools for development such as parallel compiler and its library. However, these resources are expensive for the investation and maintenance, hence people need some alternatives. Many people then introduced parallel distributed computing by using available computing resource such as PCs. Each of these PCs is treated as a processors, hence the cluster of the PC behaves as Multiprocessors Computer. Many tools are developed for such purposes.This paper studies the peformance of the currently popular tools such as Parallel Virta\ual Machine (PVM), Message Passing Interface (MPI), Java Remote Method Invocation (RMI) and Java Common Object Request Broker Architecture (CORBA). Some experiments were conducted on a cluster of PCs, the results show significant speed up. Each of those tools are identified suitable for a certain implementation and programming purposes."

"Tomato fruit is one of agroproducts that has high-economic value in the world particularly inIndonesia. To compete in a worldwide market a tomato fruit producer must produce fresh or processedtomato with high quality. High quality tomato products are influenced by the application of post-harvesttreatment or processing. One of the vital process in post-harvest treatment is sortation. Mannualsortation introduces subjectivity (bias), inaccuracy, slowness and inconsistency. This needs moreintelligent sortation methods and tools that overcome the sort comings of manual process. ProbabilisticNeural Network (PNN) is one of Artificial Neural Network (ANM variants that can be to develop acomputer-based sortation engine for tomato fruits. However, to accelerate the sortation process, parallelcomputation is employed allowing multiple processors to execute simultaneously the sortation process.This research is aimed towards the implementation and testing of a parallel computation algorithm withPNN to perform sortation for tomato fruits. Some criteria being observed and tested include accuracy,total execution time, speedup, and efficiency compared to sequential algorithm. The experimental resultsshow that the application of parallel computation algorithm with PNN introduces the increase ofaccuracy, total execution time, speedup, and efficiency with the same accuracy."

Batas atas kedalaman lapisan sumber ekivalen dipol dengan penyimpanan rata-rata di bawah 10 % berkisar 3 kai spasi pengukuran sedang batas bawah kedalaman lapisan sumber ekivalen dipol tergantung pada dimensi sumber anomali "

"This research is a correlation study between learning approach and achievement in mathematics of third grade science major of "X" Senior High School in Bandung. The samples selection for this research used simple random sampling method and the samples of this research are 60 students. The instrument used to collect the data about learning approach was adapted from questionnaire that was developed by John Biggs (1987). It is called The Revised Two-Factor Learning Process Questionnaire (R-LPQ-2F) that consist of 40 items. With the validation starting from 0.401 until 0.795 and the reliability is 0.638. Whereas the instrument used to measure achievement in mathematic is from final score of mathematic major. The collected data was mannered by Spearman's correlation using SPSS 15. From the final result we can see that the correlation between surface approach and mathematic final score is 0.062 and the correlation between deep approach and mathematic final score is 0.155. The conclusions are there is no significant correlation between surface approach and mathematic final score, and also there is no significant correlation between dep approach and mathematic final score"
