Judul: vAnalisis Efisiensi Bank Syariah di Indonesia Periode 2014-2018 dengan Metode Data Envelopment Analysis
Abstrak: Perkembangan bank syariah terus meningkat dan menimbulkan persaingan ketat antara bank syariah maupun antara bank konvensional di Indonesia. Bank syariah harus meningkatkan kinerjanya agar bank syariah tetap bertahan di industri perbankan dan tetap terus mendapatkan keuntungan maksimal. Untuk mengetahui kinerja bank syariah diperlukan analisis efisiensi. Tujuan penelitian ini adalah menganalisis tingkat efisiensi perbankan syariah dari tahun 2014 hingga 2018. Penelitian ini, termasuk meneliti apakah terdapat perbedaan tingkat efisiensi antara bank umum syariah dengan unit usaha syariah dan antara bank anak perusahaan BUMN dan bank bukan anak perusahaan BUMN. Metode yang digunakan dalam penelitian ini adalah Data Envelopment Analysis (DEA) dengan pendekatan intermediasi. Hasil penelitian menunjukan bahwa terdapat 1 (satu) bank yang terus mengalami efisiensi dari tahun 2014 hingga tahun 2018. Sementara itu, 14 (empat belas) bank lainnya mengalami efisiensi yang fluktuatif disetiap tahunnya. Rata-rata tingkat efisiensi bank syariah dari tahun 2014 hingga 2018 tergolong cukup tinggi. Tidak terdapat perbedaan tingkat efisiensi yang signifikan antara bank umum syariah dan unit usaha syariah begitu juga antara bank syariah anak perusahaan BUMN dan bank syariah bukan anak perusahaan BUMN.

Judul: Efficiency Analysis of Islamic Foreign Exchange Banks and Non Foreign Exchange Islamic Banks in Indonesia for the 2015-2019 Period
Abstrak: Meningkatnya perkembangan bank di Indonesia membuat Bank Indonesia mengizinkan bank umum untuk melakukan kegiatan usahanya dalam valuta asing sebagai upaya memperluas pasar perbankan melalui segi funding dan juga lending. Agar dapat berkompetisi secara global, perbankan dituntut untuk mempunyai kinerja yang baik. Tujuan penelitian ini adalah menganalisis tingkat efisiensi perbankan syariah dari tahun 2015 hingga 2019 dan juga menganalisis signifikansi perbedaan tingkat efisiensi antara bank syariah devisa dengan bank syariah non devisa. Metode yang digunakan dalam penelitian ini adalah Data Envelopment Analysis (DEA) dengan pendekatan produksi dan asumsi Variable Return to Scale (VRS). Hasil penelitian yang berorientasi pada output ini menunjukkan bahwa terdapat satu bank syariah devisa yang terus mengalami inefisiensi dan satu bank syariah non devisa yang mengalami efisiensi fluktuatif dari tahun 2015 hingga 2019. Sementara itu terdapat tujuh bank syariah lainnya mengalami efisiensi optimal di setiap tahunnya. Tidak terdapat perbedaan yang signifikan terhadap tingkat efisiensi bank syariah devisa dan bank syariah non devisa., The increasing development of banks in Indonesia has prompted Bank Indonesia to allow commercial banks to conduct their business activities in foreign currencies as an effort to expand the banking market through funding and lending. In order to compete globally, banks are required to have good performance. The purpose of this study is to analyze the efficiency level of Islamic banking from 2015 to 2019 and also to analyze the significance of the difference in the level of efficiency between foreign exchange Islamic banks and non foreign exchange Islamic banks. The method used in this research is Data Envelopment Analysis (DEA) with a production approach and the assumption of Variable Return to Scale (VRS). The results of this output-oriented research show that there is one foreign exchange Islamic bank that continues to experience inefficiency and one non- foreign exchange Islamic bank that experiences fluctuating efficiency from 2015 to 2019. Meanwhile, there are seven other Islamic banks experiencing optimal efficiency every year. There is no significant difference to the efficiency level of foreign exchange Islamic banks and non foreign exchange Islamic banks.

Judul: Characteristic of chili drying (Capsicum annum L.) as a natural dyeing cosmetic
Abstrak: Chilli (Capsicum sp.) contains carotenoids, which are a group of natural pigments consist of red, orange or yellow color. Carotenoids can be dissolved in lipid so that they can be applied to oil-based cosmetic ingredients. Therefore, chilli is potential to be developed as cosmetic colorants. However, pungency of red chili needs to be removed because it is irritating and it provides stinging sensation to skin. Red chilli was investigated as a potent material for a cosmetic colourant in this research because it has a nice uniform red color and has a pungency level less than cayenne pepper. The purpose of this research was to investigate the influence of blanching on drying characteristics of red chilli using a tray dryer, determine the proper time of chili blanching in sodium bisulfite solution, examine color changes stability of red chili powder as a cosmetic dye, and analyze the effect of oleoresin extraction on color and pungency level of red chili powder. The results showed that blanching could affect the drying characteristics. Blanching the chilli for 9 minutes prior drying could speed up the drying rate of chilli and thus the drying time, therefore, the chilli achieved the desired moisture content fast. Sodium bisulfite solution of 0.2%, used as the blanching media, could maintain the color well. However, longer time of blanching might cause several pigments soluble in the blanching media. Blanching the chilli for 9 minutes was able to maintain red color after the stability tested and after extraction of oleoresin. Therefore, blanching red chilli in a solution of 0.2% sodium bisulfite for 9 minutes prior drying is concluded as the best treatment to retain the color of red chilli powder
