Abstract

A research on the extraction of lead(II) ion has been done using emulsion liquid membrane technique. This research used a laboratory experiment method by using benzoyl acetone as a carrier, paraffin liquid as the membrane, a solution of nitric acid as an internal phase, Span-80 as surfactant, and a solution of lead(II) as the sample solution. This research was conducted to determine the optimum extraction condition of lead(II) ions in solution which includes a volume ratio of emulsion to external phase and extraction capacity of lead(II) ion by emulsion liquid membrane technique. The volume ratio of emulsion to external phase used was 1:5, 1:6, 1:7, and 1:8. While the variation of concentration of lead(II) used was 220 ppm, 434 ppm, 695 ppm, and 817 ppm. The determination of the concentration of lead(II) ions in external phase is done by using a spectrophotometer SpectroDirect. The results of this research showed that the volume ratio of emulsion to external phase were in the maximum extraction percentage; 1:6 ratio. Moreover, the concentration of lead(II) were in maximum extraction percentage of 220 ppm with extraction percentage of 56.36%.

Abstract

Profitability is one benchmark to show a company operational performance. Various factors influence the amount of profitability. This research aims to analyze the influence of the amount of premium income, total investment, claims expense and operational costs on the profitability gained during the period 2011-2017. This paper conducts multiple linear analysis, namely OLS (Ordinary Least Square) with secondary data in the form of time-series data. The results of the t-test indicate that the claims expense variable has a negative and significant effect. Meanwhile, the operational cost variable has a positive and significant impact. On the contrary, the premium variable and the amount of investment both have a positive but not significant effect. Moreover, the results of the F test show that the variables of premium, investment, claims expense and operating costs have a considerable impact on the profitability of Sinar Mas Islamic Insurance.

Abstract

Konvergensi media merupakan persimpangan media lama dan media baru, yang tidak saja akibat pergeseran teknologi namun juga berdampak pada pergeseran paradigma industri, budaya dan sosial. Karena itu mediamorfosis menjadi pilihan industri media dalam mempertahankan eksistensi dirinya. MoeslimChoice sebagai bagian dari media Islam turut bertransformasi sehingga mengubah strategi bisnisnya melalui situs berita online dan layanan TV streaming. Transformasi media ini menunjukkan apa yang disebut oleh Roger Fidler (1997) sebagai mediamorphosis dan atau konsep konvergensi media dari Nicholas Negroponte.Penelitian ini menggunakan paradigma konstruktivis, pendekatan kualitatif dan studi kasus.  Pengumpulan data dilakukan dengan menggunakan teknik observasi, telaah pustaka dan wawancara mendalam.Temuan penelitian ini menunjukkan MoeslimChoice itelah melakukan mediamorfosis dengan memperluas platformdari media cetak ke digital. Mediamorfosis dilakukan melalui koevolusi, konvergensi dan kompleksitas. Di antara tiga konsep mediamorfosis, konvergensi lah yang menjadi esensi dari perubahan yang dilakukan MoeslimChoice. Pada konvergensi kontinum yang terfokus pada ruang redaksi, MoeslimChoice telah mencakup kelima tahapannya. Meskipun pencapaian ini masih belum sempurna. Sedangkan pada konvergensi jurnalistik yang terfokus pada isi atau konten liputannya, MoeslimChoice dominan menggunakan model konvergensi newsgathering, yang mana kemampuan multitasking seorang jurnalis sangat diutamakan.
