ABSTRAK
Setelah teori relativitas ditemukan oleh Albert Einstein, maka pandangan para ilmuwan mengenai dunia banyak berubah. Dengan adanya teori relativitas umum yang diterapkan dalam teori gravitasi mengakibatkan penelitian mengenai antariksa meningkat pesat. Khususnya bintang-bintang yang memiliki kepadatan tinggi dimungkinkan untuk dipelajari sifat-sifatnya. Dalam penelitian ini akan dipelajari hubungan antara massa dengan jari-jari dan hubungan momen inersia dengan jari-jari pada bintang neutron khususnya untuk daerah crust. Untuk mendapat hasil yang diinginkan, tesis ini akan menggunakan pendekatan medanrata- rata relativistik dengan solusi akan didapatkan dari persamaan TOV. Program Fortran akan digunakan untuk menghitung solusi persamaan TOV tersebut.

ABSTRACT
After Albert Einstein established his theory of relativity, a lot of scientist views of the world were changed. With the existence of the general theory of relativity that is applied in the theory of gravity, there is a rapid increase in research concerning the outer space. Moreover, the researches concerning the characteristics of high density stars are now possible to be conducted. In this thesis, I will describe the relations between the mass and the moment of inertia of a neutron star with its radius especially in the crust area. To achieve the aim of this thesis, I will use relativistic mean-field approach with solution acquired from TOV equation. The TOV equation’s solution will be calculated by the Fortran Program.

Saat ini di Indonesia, meskipun belum banyak literatur yang membahas schutznorm theorie (teori relativitas) secara khusus, tetapi telah terdapat perbedaan dalam penerapannya. Setidaknya terdapat 2 (dua) putusan yang menggambarkan perbedaan penerapan ini, yakni putusan nomor 48/Pdt.G/2016/PN.Njk dan putusan nomor 13/Pdt.G/2014/PN.Sbg. Oleh karena itu, tulisan ini akan membahas bagaimana sebenarnya hubungan antara schutznorm theorie dengan perbuatan melawan hukum dan menganalisis penerapannya dalam perkara gugatan perbuatan melawan hukum. Penelitian ini berbentuk yuridis-normatif yang bersifat deskriptif-analitis dengan menggunakan metode analisis kualitatif berdasarkan studi dokumen. Hasil dari penelitian ini menemukan bahwa schutznorm theorie dapat digunakan untuk menentukan hak gugat dalam perkara gugatan perbuatan melawan hukum dan terdapat perbedaan penerapan schutznorm theorie dalam perkara gugatan perbuatan melawan hukum. Dengan demikian perlu diatur pedoman penerapannya untuk menjamin kepastian hukum dan keadilan, dimana pedoman ini sebaiknya diatur dalam Peraturan Mahkamah Agung (Perma) yakni bahwa hukum acara perdata mengenal adanya schutznorm theorie untuk menentukan hak gugat, sebagaimana kedudukan legal standing dalam gugatan di MK RI sehingga dapat diperiksa lebih dulu sebelum masuk pokok perkara sebagaimana dismissal process di PTUN. ......Currently in Indonesia, although not much literature has specifically discussed the schutznorm theory (relativity theory), there have been differences in its application. There are at least 2 decisions that illustrate the difference: verdict number 48/Pdt.G/2016/PN.Njk and verdict number 13/Pdt.G/2014/PN.Sbg. Therefore, this paper will discuss how the actual relationship between schutznorm theory and tort and analyze its application in tort lawsuits. This research is in the form of juridical-normative, which is descriptive-analytical, by using qualitative analysis method based on document study. The results of this study found that schutznorm theory can be used to determine the right to sue in tort lawsuits and there are differences in the application of schutznorm theorie in tort lawsuits. Thus, it is necessary to set guidelines for its application to guarantee legal certainty and justice, where these guidelines should be regulated in a Supreme Court Regulation (PERMA), that civil procedural law recognizes the existence of the schutznorm theory (relativity theory) to determine the right to sue, such as legal standing to file a lawsuit at the Constitutional Court of Republic Indonesia so that it can be examined first before entering the main case, such as the dismissal process at the State Administrative Court of Republic Indonesia.

Symmetries, coupled with the mathematical concept of group theory, are an essential conceptual backbone in the formulation of quantum field theories capable of describing the world of elementary particles. This primer is an introduction to and survey of the underlying concepts and structures needed in order to understand and handle these powerful tools. Specifically, in Part I of the book the symmetries and related group theoretical structures of the Minkowskian space-time manifold are analyzed, while Part II examines the internal symmetries and their related unitary groups, where the interactions between fundamental particles are encoded as we know them from the present standard model of particle physics. This book, based on several courses given by the authors, addresses advanced graduate students and non-specialist researchers wishing to enter active research in the field, and having a working knowledge of classical field theory and relativistic quantum mechanics. Numerous end-of-chapter problems and their solutions will facilitate the use of this book as self-study guide or as course book for topical lectures.

Einstein, the world-renowned scientist, was also publicly committed to radical political views. Despite the vast literature on Einstein, this book is the first comprehensive study of his politics, covering his opinions and campaigns on pacifism, Zionism, control of nuclear weapons, world government, and freedom over his whole career. Most studies look at Einstein in isolation, but here he is viewed alongside a liberal international of global intellectuals, including Gandhi, Albert Schweitzer, Bertrand Russell, H. G. Wells, George Bernard Shaw, Romain Rolland, Thomas Mann, and John Dewey. Frequently called upon to join campaigns on great issues of war, peace, and social values, they all knew or corresponded with Einstein. The book is concerned with how Einstein and comparable intellectuals sought to exert a salutary moral influence, as Einstein put it in a letter to Freud, which in practice amounted to a non-political form of politics. Close attention is given to the unique qualities Einstein brought to his interventions in political debate and in particular to the struggles he experienced in retaining control of his message. His influence derived in the first instance from his celebrity status as the scientist of genius. Einsteins complex and enigmatic personality, which combined intense devotion to privacy and a capacity to perform on the public stage, also contributed to the Einstein myth. Studying Einsteins politics takes us not only into the mind of Einstein but also to the heart of the great public issues of the twentieth century.
