Reflexivity of Intellectual Capital to Assets in Jakarta Islamic Index with Hahslm Approach

Abstract This study aims to examine the reflexivity of value added of intellectual capital that consist of three components from company sources (human capital, capital employed, structural capital) towards company’s financial performance which is listed in Jakarta Islamic Index with Hahslm approach. These values added of intellectual capital has close relation with the well being function of the company. The population in this study has 30 companies that were listed in the Jakarta Islamic Index within the period 2013–2016. The sampling technique is used as subjective sampling based on 17 companies. This study uses secondary data that is obtained from the Indonesia Stock Exchange. Theory H shows the test with religiosity perspective [3]. The hypothesis of this study has been tested by using partial least square (PLS). The method used is VAIC from public information which is made into separate variables that are connected to the company’s financial performance (ROA). The results showed that VAHU has no significant influence on the company’s financial performance and so did STVA, while VACA has a significant effect on company’s financial performance. From the result, the study showed that company should have well-being function to have a significant influence on the company’s financial performance.     Keywords: human, capital, structure, RO

Kontribusi Terhadap Kuliah Perancangan Mesin Listrik Dalam Pendidikan Teknik Tenaga Listrik Di Indonesia

Dalam dunia industri, mesin tak serempak banyak digunakan sebagai penggerak utama. Selain itu, sebagai generator mesin ini memungkinkan pembangkitan energi listrik secara otonom di daerah-daerah terpencil. Mengingat pentingnya peran mesin ini, makalah ini dibuat untuk sedikit memberikan kontribusi dalam kuliah perancangan mesin listrik bagi mahasiswa teknik tenaga listrik pada khususnya. Kontribusi yang diberikan berupa tambahan pemahaman terhadap penerapan teori elektromaknitik dalam perhitungan induktansi bocor cincin ujung rotor sangkar saat perancangan mesin tak serempak. Akan ditunjukkan bagaimana beberapa anggapan penyederhanaan diambil agar memungkinkan proses perhitungan dengan menggunakan teori dasar elektromaknetika. Perhitungan analitik berdasarkan metoda bayangan, yang pada umumnya sudah dipelajari dalam kuliah dasar teori elektromaknitik, dibandingkan dengan perhitungan secara analitik-empirik serta dengan perhitungan menggunakan metoda numerik berdasarkan metode elemen terbatas. Dengan memanfaatkan metoda bayangan, induktansi diperoleh melalui penghitungan fluksi yang tercakup total menggunakan vektor potensial. Sebagai pembanding, induktansi juga telah diperoleh dengan menghitung impedansi cincin. Selanjutnya, perhitungan induktansi menggunakan perangkat lunak berdasarkan metoda elemen terbatas juga telah dilakukan melalui penghitungan energi maupun fluksi. Hasil perhitungan analitik menunjukkan adanya kesesuaian dengan hasil numerik, dengan keuntungan metode bayangan lebih sederhana dan mudah untuk diterapkan dibandingkan dengan metode elemen terbatas yang hingga kini seringkali masih terbentur pada lama proses penghitungan serta keterbatasan daya hitung komputer.Kata-kata Kunci — Vektor potensial, Metode bayangan, Fungsi eliptik
