Abstract

ABSTRACT A phoswich or sandwich-type scintillation detector consisted of a thin layer of ZnS(Ag) and a plate of NE 102A plastic scintillator and a single crystal-type CsI(Tl) scintillation detector have been applied to differentiate alpha- and beta (X, gamma)- particles by means of pulse shape discrimination (PSD) technique. In this experiment, rise time distributions of alpha- and beta-particles have been measured with uses of a couple of sources of 241Am and 90Sr (90Y) and a 93.3% enriched uranium-aluminum alloy. Rise time resolution of the PSD spectrometer has been measured as 8.8ns ± 1.2% in terms of FWHM (FWTM: l6.3ns), which has been measured with a pulse generator. The most probable rise times of ZnS(Ag)/NE 102A detector have been obtained as 1.473µs ± 0.3% with the FWHM of 40ns for alpha-particles (ZnS(Ag)) and as 32.2ns ± 4.8% with the FWHM of 18ns for beta (X, gamma)-particles (NE l02A). The most probable rise time of the CsI(Tl) detector has been determined as 1.288µs ± 0.l% with the FWHM of 54ns for alpha-particles and as 1.435µs ± 0.l% with the FWHM of 44ns for beta (X, gamma)-particles. It has been clarified that the PSD system equipped with the ZnS(Ag)/NE 102A and the CsI(Tl) detectors gives clearly differentiated count rates and spectra of alpha- and beta (X, gamma)-particles, and application of the PSD system to, for example, screening-out of the radwastes contaminated with alpha-emitters is expected to be very effective.

Abstract

Legal issues must be studied scientifically through various legal studies so as to be able to present the right solution. Legal research itself must use methods that are in accordance with existing legal problems. This research method is urgent because it will determine the truth or validity of the results of a study. Inappropriate methods affect the results of the study itself. Broadly speaking, legal research methods are divided into two, namely empirical and normative. Normative legal research is influenced by pure legal doctrine. The discussion in this research is more about why normative juridical methods are needed in proving the truth in legal research?, and what is the mechanism for using normative juridical methods in proving the truth in legal research?. This study aims to analyze the urgency of using normative juridical methods in proving the truth in legal research, and to find out the mechanisms and stages that must be carried out in using normative juridical methods in proving the truth in legal research. The statutory approach is very important to use in analyzing a legal problem, the settlement of issues or legal problems must of course be based on constructive arguments and on the basis of rules or positive law. The stages in normative legal research begin with secondary data collection through literature study, then analysis is carried out using deductive logical thinking. deductive by emphasizing norms, jurisprudence and doctrine. Then the final stage is the researcher by making a decision or a conclusion.

Abstract

Perjanjian Pra Nikah adalah perjanjian yang dibuat sebelum dilangsungkannya pernikahan dengan tujuan untuk melindungi hak dan kewajiban suami istri setelah menikah. Isi Perjanjian Pra Nikah biasanya meliputi pemisahan harta sebelum pernikahan, pemisahan hutang sebelum pernikahan, selama pernikahan, atau bahkan setelah perceraian. Melalui perjanjian ini, masing-masing pihak dapat menentukan harta bawaan masing-masing suami istri dan harta benda yang diperoleh masing-masing sebagai hadiah atau warisan berada di bawah penguasaan masing-masing sepanjang tidak ditentukan lain. Perjanjian Pra Nikah ini banyak dipilih untuk calon pasangan yang salah satu atau keduanya punya resiko tinggi dalam pengelolaan keuangan, misalnya calon pasangan  seorang politikus atau pengusaha. Metode yang digunakan dalam kajian ini menggunakan metode yuridis normatif. Perlindungan hukum terhadap harta bawaan dalam perjanjian Pra Nikah bertujuan untuk memproteksi terhadap harta masing-masing calon pasangan dimana para pihak dapat menentukan harta bawaan masing-masing, hutang yang dimiliki calon pasangan menjadi tanggung jawab masing-masing, menjamin berlangsungnya harta peninggalan keluarga serta menghindari motivasi perkawinan yang tidak sehat. Akibat hukum dari Perjanjian Pra Nikah terhadap harta bawaan dalam perkawinan, baik harta yang diperoleh dari usaha masing-masing maupun dari hibah, warisan ataupun cuma-cuma yang diperoleh masing-masing selama perkawinan berada dalam penguasaan masing-masing kecuali ditentukan lain.
