Abstract

Rainfall simulator is important for studying hydrology and erosion in laboratory.  The most important parameter for studying the performance of rainfall simulator is rain intensity, drop size distribution, drop mass, drop impact velocity, and kinetic energy.  They are evaluated by uniformity coefficient (UC) and distribution uniformity (DU). This research was aimed to study the functional performance of rainfall simulator including determination of the correlation between pressure with rainfall parameters (rain intensity, drop size distribution, and kinetic energy) and rainfall simulator performance evaluation based on uniformity coefficient and distribution uniformity.  The data was analyzed by using linear regression and evaluated by uniformity coefficient and distribution uniformity.The result showed that pressure had linear relationship with rain intensity, diameter drop distribution, drop impact velocity, dropped mass, and kinetic energy.  The coefficient uniformity (CU) of the pressure 2.5 psi-6.5 psi  more than 80% and the distribution uniformity (DU) more than 70%. The rainfall simulator had better performance at the pressure of 2.5 psi than 6.5 psi.Keywords: rainfall, simulator, performance

Abstract

The purpose of this study was to determine the influence of competence and supervision on employee performance. The hypothesis in this study is that there is an influence of competence and supervision either partially or simultaneously on employee performance. The sample used in this study amounted to 36 employees. Data collection techniques include observation, documentation and questionnaires. The data analysis method used a quantitative approach with the help of SPSS version 21.0 statistical tools including the calculation of the validity test, reliability test, linear regression test, t test, F test and coefficient of determination test. The results of testing the hypothesis of the influence of competence on performance partially show that competence has a positive influence on performance with a contribution of 50.6%. Supervision has a positive influence on performance with a contribution of 41.3%. Simultaneous hypothesis testing shows that competence and supervision together have a positive influence on performance

Abstract

Kebijakan fiskal adalah kebijakan yang mempengaruhi anggaran pendapatan danbelanja suatu negara. Anggaran pendapatan dan belanja negara merupakan rencana pendapatan serta pengeluaran yang akan diperoleh dan dibayarkan oleh negara selama setahun, komponen pendapatan negara dalam perekonomian modern dewasa ini dibedakan antara pajak dan bukan pajak. Penerimaan dari pajak terdiri atas pajak langsung dan pajak tidak langsung. Sedangkan penerimaan bukan pajak contohnya adalah bantuan atau sebenarnya lebih tepat dikatakan sebagai utang luar negeri.Dalam Islam kita sudah mempelajari jenis-jenis penerimaan baitul maal yang, antara lain, terdiri atas zakat, infaq, sadaqah, wakaf, fa’i, ghanimah, khums, dan kharaj. Kebijakan fiskal Islami adalah bagaimana pemerintah memaksimalkan penerimaannya dari jenis-jenis penerimaan tersebut, yang dalam bahasa modern disederhanakan dalam bentuk ‘pajak’. Selanjutnya, tugas pemerintah yang Islami-lah bagaimana mengelola pengeluaran dan belanja negara untuk mencapai tujuan-tujuan yang dikehendaki oleh syariah sesuai dengan cara-cara yang dibenarkan oleh Allah  dan Rasulullah Muhammad  Kata Kunci: Zakat, Kebijakan Fiskal
