Abstract

The non-linear optical property of rotary power of light polarization in water and salt solution has been developed using the Radio-Frequency field (RF-Field). The RF-Field used in the experiment is produced by RF generator, and it supplies the frequency in the range between 6.04 to 14.56 MHz, which then applies to the samples. The source of light with 632.8 nm-wavelength and 532 nm-wave length are used to observe the change of angle polarization of the light, after it passes through the samples. Three modes of the direction of the electric field of light are chosen 0o (E//) (E of light is parallel to E of RF-Field, and 90o (E^) (E of light is perpendicular to E of the RF-Field) in order to determinate the optimal change of the angle of the polarization. The values of  is measured as a function of RF-Field, , where  is the angular frequency of RF-Field and BRF is the magnitude of magnetic field measured in the center of the coil which is assumed to be homogeny in the circumstances of the samples. The results of the experiment show that the degrees of change of the polarization direction, is largest at the  mode. It shows also that at small wavelength of light we obtain the larger, which is indicated the higher frequency of light will more induce the dipoles of molecules of the samples. Keywords: non-linear optics, polarization angle, rotary power

Abstract

ABSTRACT-The non-linear optical property of rotary power of light polarization in water has been develop using the Radio-Freguency field (RF-Field). The RF-Field used in the experiment is produced by RF generator, and it supplies the frequency in the range betwen 6,04 to 14,56 MHz which then applies to the samples. The source of light with 632,8 nm-wavelength and 532 nm-wavelength are used to observe the change of range polarization of the light after it passes througt the samples.  Three modes of the direction of the electric field of light are chosen 0o (E//) (E of light is parallel to E of RF-Field), and 90o (E ) (E of light is perpendicular to E of the RF-Field) in order to determinate the optimal change of the angle of the polarization β. The values of β is measured as a function of RF-Field,  , where ωRF is the angular frequency of RF-Field and  BRF is the magnitude of magnetic field measured in the center of the coil which is assumed to be homogeny in the circumstances of the samples. The results of the experiment show that the degrees of change of the polarization direction, η is largest at the E3 mode. It shows also that at small wavelength of light we obtain the larger η, which is indicated the higher frequency of liglt will more induce the dipoles of molecules of the samples. Keywords:  non- linear optics, polarization angle, rotary power

Abstract

Studi ini menguji pengaruh karakteristik perusahaan terhadap luasnya pengungkapan Corporate Social Responsibility (CSR) dalam pelaporan keuangan perusahaan. Motivasi pengujian karakteristik perusahaan terhadap luas pengungkapan CSR dalam studi ini dilandasi oleh temuan pengujian sebelumnya yang masih kurang konsisten. Luas pengungkapan CSR diukur menggunakan skor pengungkapan Global Reporting Initiative (GRI) tahun 2002, sedangkan karakteristik perusahaan diwakili dengan profitabilitas, likuiditas, solvabilitas, dan ukuran perusahaan. Dengan menggunakan sampel final sebanyak 82 firm years dari perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia (BEI), dan menggunakan regresi berganda, ditemukan sebagian bukti bahwa karakteristik entitas berpengaruh terhadap luas pengungkapan CSR. Kami menemukan bahwa ukuran perusahaan (size) berpengaruh positif terhadap tingkat pengungkapan CSR pada pelaporan keuangan, konsisten dengan temuan penelitian sebelumnya (misalnya, Hackson & Milne, 1996; Sembiring, 2005; dan Prihandono, 2010). Namun profitabilitas, likuiditas, dan solvabilitas tidak terbukti berpengaruh pada pengungkapan CSR. Penjelasan alternative dari temuan ini adalah bahwa regulasi dalam CSR, sebagaimana diatur dalam Undang-undang (UU) No 40 dan UU No 25 tahun 2007 turut menciptakan iklim penerapan kegiatan CSR bagi seluruh perusahaan publik secara mandatory dan tidak lagi bersifat voluntary, sehingga karakteriktik perusahaan (profitabilitas, solvabilitas, maupun likuiditas) diduga menjadi kurang relevan terhadap tingkat pengungkapan CSR.   Kata kunci: pengungkapan tanggung jawab sosial (CSR), profitabilitas, likuiditas, solvabilitas, ukuran perusahaan

Abstract

Pondok pesantren memainkan peran penting dalam pendidikan agama Islam di Indonesia, khususnya dalam pendidikan Al-Qur'an dan budi pekerti. Yayasan Bina Prestasi Tahfidz Indonesia didirikan untuk menyediakan pendidikan berkualitas bagi anak-anak dari keluarga kurang mampu, terutama yang berada di luar Pulau Jawa. Dengan 11 cabang Rumah Qur'an yang tersebar di Jabodetabek, yayasan ini memberikan akses pendidikan agama dan Al Qur’an yang kuat. Saat ini, santri di setiap Rumah Qur'an dibatasi untuk mengelola uang secara pribadi, untuk menghindari resiko terjadinya kehilangan. Sebagai solusinya, mereka menitipkan uang kepada pengurus Rumah Qur’anmasingmasing. Namun, pencatatan tabungan santri di yayasan ini masih dilakukan secara manual, yang menyebabkan masalah administratif dan meningkatkan risiko kesalahan. Untuk mengatasi hal ini, diperlukan implementasi sistem informasi berbasis website untuk pencatatan keuangan santri yang lebih efisien dan akurat. Penelitian ini menggunakan metode waterfall, yang meliputi analisis kebutuhan sistem, perancangan, implementasi, uji coba, dan evaluasi, untuk merancang sistem informasi buku tabungan elektronik santri berbasis website bernama TASBI (Tabungan Santri Bina Prestasi). Sistem ini dirancang menggunakan HTML, Javascript, CSS, PHP, dan MySQL. Hasil penelitian adalah sebuah sistem informasi buku tabungan santri berbasis web yang bernama TASBI yang dapat meningkatkan efisiensi operasional, transparansi, dan akuntabilitas dalam pengelolaan tabungan santri
