AbstrakPenelitian ini dilatarbelakangi oleh menguatnya wacana mengenai pentingnya perlindungan data pribadi  dan terbitnya Peraturan Menteri Komunikasi dan Informatika Nomor 20 Tahun 2016 tentang Perlindungan Data Pribadi dalam Sistem Elektronik. Adapun tujuan penelitian adalah untuk mengetahui kinerja implementasi Peraturan Menteri tersebut di lingkungan Pemerintah Kabupaten. Penelitian  dilakukan di Dinas Kependudukan dan Pencatatan Sipil pada Pemerintah Kabupaten Gianyar, Temanggung, dan Sleman dengan menggunakan metode studi kasus, sedangkan pengum­pu­lan data menggunakan teknik studi pustaka, wawancara, dan observasi. Pembahasan dilakukan dengan menggunakan konsep implemen­tasi model Edwards yang melihat implementasi berdasarkan variabel komunikasi, sumber-sumber, kecenderungan-kecenderu­ngan, dan struk­tur birokrasi. Hasil penelitian menunjuk­kan bahwa penyelenggaraan administrasi kependudukan yang di dalamnya termasuk perlindungan data pribadi oleh Dinas Kependudukan dan Pencatatan Sipil merujuk pada Peraturan Menteri Dalam Negeri Nomor 61 Tahun 2015, sedangkan Peraturan Menteri Komunikasi dan Informatika Nomor 20 tahun 2016 sama sekali belum mereka ketahui. AbstractThis research is motivated by the strengthening of discourse regarding the importance of protecting personal data and the issuance of Minister of Communication and Information Regulation No. 20 of 2016 concerning Protection of Personal Data in Electronic Systems. The research objective is to determine the performance of the implementation of the Ministerial Regulation within the District Government. The study was conducted at the Department of Population and Civil Registration at the Government of the Regency of Gianyar, Temanggung, and Sleman by using a case study method, while data collection using literature study techniques, interviews, and observations. The discussion was carried out using the concept of implementation of Edwards model that looked at implementation based on communication variables, sources, trends, and bureaucratic structure. The results showed that the administration of population administration which included the protection of personal data by the Population and Civil Registry Office referred to the Minister of Home Affairs Regulation No. 61 of 2015, while the Minister of Communication and Information Regulation No. 20 of 2016 was completely unknown to them.

The paper presents a coordinate-free analysis of deformation measures for shells modeled as 2D surfaces. These measures are represented by second-order tensors. As is well-known, two types are needed in general: the surface strain measure (deformations in tangential directions), and the bending strain measure (warping). Our approach first determines the 3D strain tensor E of a shear deformation of a 3D shell-like body and then linearizes E in two smallness parameters: the displacement and the distance of a point from the middle surface. The linearized expression is an affine function of the signed distance from the middle surface: the absolute term is the surface strain measure and the coefficient of the linear term is the bending strain measure. The main result of the paper determines these two tensors explicitly for general shear deformations and for the subcase of Kirchhoff-Love deformations. The derived surface strain measures are the classical ones: Naghdi’s surface strain measure generally and its well-known particular case for the Kirchhoff-Love deformations. With the bending strain measures comes a surprise: they are different from the traditional ones. For shear deformations our analysis provides a new tensor [Formula: see text], which is different from the widely used Naghdi’s bending strain tensor [Formula: see text]. In the particular case of Kirchhoff–Love deformations, the tensor [Formula: see text] reduces to a tensor [Formula: see text] introduced earlier by Anicic and Léger (Formulation bidimensionnelle exacte du modéle de coque 3D de Kirchhoff–Love. C R Acad Sci Paris I 1999; 329: 741–746). Again, [Formula: see text] is different from Koiter’s bending strain tensor [Formula: see text] (frequently used in this context). AMS 2010 classification: 74B99
