[ABSTRAK
Pada laporan akhir tesis ini telah dikembangkan suatu sistem untuk magnetisasi bahan magnet menjadi magnet permanen dan demagnetisasi dengan mengurangi kuat medan magnet suatu magnet permanen. Sistem ini digunakan untuk magnetisasi bahan magnet seperti Ferit, PrFeB, NdFeB dan jenis bahan magnet yang lain. Bahan magnet dapat dimagnetisasi menjadi magnet permanen dengan menerapkan medan magnet sampai diatas titik saturasi magnet dari bahan magnet pada waktu singkat atau dikenal dengan impulse magnetizer. Penerapan medan magnet menghasilkan momen magnetik dan memaksa domain-domain magnetik secara bertahap mengikuti arah medan magnet yang diterapkan. Jika medan magnet eksternal lebih kuat dari medan magnet saturasi magnetik dari bahan magnet maka domain-domain magnetik akan diorientasikan dengan arah yang baru. Sistem ini menggunakan kapasitor untuk menyimpan muatan listrik dan kemudian diterapkan pada lilitan kawat berbentuk solenoid multi lapis. Pada tesis ini telah berhasil melakukan magnetisasi dan demagnetisasi bahan magnet Ferit, PrFeB dan NdFeB dengan ukuran bahan maksimal 26mm.

ABSTRACT
On this nal thesis report has been developed a system for the magnetization of the magnetic material become permanent magnets and demagnetization by reducing the magnetic eld strength of a permanent magnet. This system is used for magnetize the magnetic material such as Ferrite, PrFeB, NdFeB magnets and other types of magnetic materials. Magnetic material can be magnetized into a permanent magnet by applying a magnetic eld above the saturation point of the magnetic material in a short time, known as impulse magnetizer. Application of a magnetic eld generates a magnetic moment and domain-domain magnetic force gradually follow the direction of the applied magnetic eld. If the external magnetic eld is stronger than the magnetic eld of a magnetic saturation of the magnetic material, the magnetic domains will be oriented to the new direction. This system uses a capacitor to store electrical charge and then applied to the multi-layer solenoid or coil by discharging process. On this thesis has been successfully doing magnetization and demagnetization magnetic materials such as Ferrite, NdFeB, PrFeB with a maximum material size of 26mm.;On this nal thesis report has been developed a system for the magnetization of the magnetic material become permanent magnets and demagnetization by reducing the magnetic eld strength of a permanent magnet.

Tugas akhir ini membahas mengenai perancangan rangkaian pembaca keluaran sensor kelembaban dan konduktivitas dielektrik dengan menggunakan Operational amplifier LT 1807. Perancangan dilakukan dengan simulasi menggunakan multisim 10.0.1 dan menerapkan hasil simulasi di papan protoboard. Berdasarkan implementasi dan pengujian rangkaian detektor fasa hasil kajian ini, didapatkan hasil yang lebih baik pada rangkaian rangkaian Pcb. Hal ini disebabkan karena capacitance stray menjadi lebih besar karena penggunaan protoboard dan noise yang disebabkan oleh adanya kabel jumper. Berdasarkan pengujian hasil optimisasi terhadap tiga nilai resistansi diatas 1 KiloOhm yang dibandingkan dengan hasil rangkaian sebelumnya didapatkan lebar pulsa beda fasa dengan margin kesalahan terhadap perhitungan sebesar 0.508°.

This project discusses about the design of output circuits readers conductivity and dielectric humidity sensor using Operational amplifier LT1807. The design was simulated using Multisim 10.0.1 and applying the simulation results in protoboard. Based on the implementation and testing phase detector circuit results of this study, obtained better results in the pcb board. This is because the stray capacitance becomes larger as the use protoboard and noise caused by the presence of jumper cables. Based on the testing results of the optimization of the three above 1 KiloOhm resistance value that is compared with the previous set of results obtained with the phase shift between pulse width to the calculation of margin of error of 0.508°.

ABSTRAK Telah dibuat suatu sistem kontrol (Elektronik dan software) untuk alat pembuat jalur sobekan dan cacahnya berbasiskan microcontroller. Sistem control ini dirancang dengan tujuan untuk mempermudah pekerjaan pada perusahaan-perusahaan percetakan kalangan kecil dan menengah yang masih menggunakan peralatan yang masih manual untuk proses pembuatan jalur sobekan kertasnya. Pada alat ini digunakan keypad dan sensor optocoupler yang berfungsi untuk mendeteksi adanya kertas yang melewatinya.. Photoemitter yang biasanya digunakan sebagai pemancar atau transmitter yaitu led dan photodetector digunakan sebagai receiver-nya. Inputan dari keypad dan outputan dari sensor optocoupler kemudian digunakan untuk manjalankan actuator yang berupa motor dc dan motor ac untuk bergerak sesuai dengan fungsinya. Selain itu untuk memperjelas hasil proses microcontroller maka ditampilkan pula dalam tampilan LCD.

ABSTRACT Have been made an control systems (software and electronic) for the appliance of paper line cutting tracker and its count bases of microcontroller. This Control system is designed as a mean to helpdown work at middle and small printing office company which still use equipments which still manual to the process of its cutting line tracker. This appliance is used by keypad and three sensor functioning optocoupler to detect the existence of paper passing it. This Sensor consist of photodetector and photoemitter. Photodetector usually used as a transmitter and Photoemitter used as a receiver. Input and output from keypad and optocoupler then used to run of actuator which in the form of dc motor and ac motor to make a move as according to its function. Besides to clarify result of microcontroller process also presented in LCD display.

We try to detect chaos structure on the capital market by searching for low dimensional chaos at the market portfolio index: IHSG. We apply BDS statistic, R/S Analysis, Correlation Dimension and Lyapunov Exponent for non linearity and chaos testing. We observe IHSG data from January 1988 until November 2003. We find nonlinearity, persistence and low dimensional chaos in IHSG

Sekuritisasi aset sudah merupakan sebuah keharusan karena kesulitan mendapatkan dana dalam kerangka ekspansi kreditnya. Disamping perusahaan juga sangat membutuhkan dana tetapi tidak dapat diperoleh dari perbankan dan untuk go public harus memenuhi berbagai persyaratan, maka sekuritisasi merupakan alternatif yang tepat. Pada sisi lain harus didirikan sebuah perusahaan yang menjamin (Gurantor) atas traskasi dikarenakan masyarakat belum memahami resiko investasi dalam bentuk sekuritisasi aset ini.

This research studies the international co-movement among Asia Pacific emerging markets stock price indices during the late 2000s recession by using the monthly observations start from 1st October 2001 until 1st April 2011. The co-integration analysis and parsimonious Vector Error Correction Model employed in this research reveal a long-term relationship and interdependencies among seven Asia Pacific emerging market stock price indices. This research finds that the unique co-integation exists on the equations. Specifically, two indices from China and Taiwan having meteor shower potential while the rest indices from Thailand, Malaysia, and Indonesia are known to have heat waves effects or country specific factors on the equation. Finally, all the results are linked to the international diversification strategies.
