Judul: Pengaruh Pembiayaan Murabahah, Mudharabah dan Musyarakah Terhadap Profitabilitas Pada Bank BNI Syariah Periode 2015-2019
Abstrak: Profitabilitas pada Bank BNI Syariah mengalami penurunan dari 1,44% menjadi sebesar 1,31% pada tahun 2016 sampai 2017 sementara pembiayaan mengalami peningkatan dari 20,49 triliun rupiah menjadi sebesar 23,59 triliun rupiah pada tahun 2016 sampai 2017. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor apa saja yang dapat mempengaruhi profitabilitas pada Bank BNI Syariah dan pengaruh dari pembiayaan murabahah, mudharabah, dan musyarakah terhadap profitabilitas pada Bank BNI Syariah periode tahun 2015 sampai 2019. Penelitian ini menggunakan data sekunder berupa laporan keuangan triwulan Bank BNI Syariah dan metode analisis yang digunakan metode analisis regresi linear berganda. Hasil analisis data menunjukkan bahwa pembiayaan murabahah, mudharabah, musyarakah, Kewajiban Penyediaan Modal Minimum (KPMM), Financing to Deposit Ratio (FDR) dan Non Performing Financing (NPF) berpengaruh signifikan terhadap ROA Bank BNI Syariah secara simultan. Secara parsial, pembiayaan mudharabah, musyarakah, FDR dan NPF berpengaruh positif terhadap ROA sedangkan pembiayaan murabahah dan CAR berpengaruh negatif terhadap ROA. Kata kunci: pembiayaan, profitabilitas, regresi linear berganda ABSTRACT AHMAD RIDHO ANANDA. The Effect of Murabahah, Mudharabah and Musyarakah Financing on Profitability at BNI Syariah Banks for The 2015-2019 Period. Supervised by DENI LUBIS and YEKTI MAHANANI. Profitability at BNI Syariah Banks decreased from 1,44% to 1,31% in 2016 to 2017 while its financing number increased from 20,49 trillion rupiah to 23,59 trillion rupiah in 2016 to 2017. This study aims to identify the factors affect the profitability of BNI Syariah Banks and the influence of murabahah financing, mudharabah, musyarakah on the profitability of BNI Syariah Banks. The data used in this study uses secondary data in the form of quarterly financial statements of BNI Syariah for the period 2015 to 2019 and the method used in this study uses multiple linear regression analysis. The results of data analysis show that murabahah financing, mudharabah, musyarakah, Capital Adequacy Ratio (CAR), Financing to Deposit Ratio (FDR) and Non Performing Financing (NPF) have significant influence on the ROA of BNI Syariah Bank simultaneously. Partially, mudharabah financing, musyarakah, Financing to Deposit Ratio (FDR), and Non Performing Financing (NPF) have a positive effect on ROA of BNI Syariah Banks. Partially, murabahah financing and Capital Adequacy Ratio (CAR) have a negative effect on ROA of BNI Syariah Banks. Keywords: financing, multiple linear regresion, profitability

Judul: Faktor-Faktor Yang Memengaruhi Pendapatan Margin Murabahah Pada Produk KPR Syariah: Studi Kasus Bank Syariah Indonesia
Abstrak: Pembiayaan KPR syariah dengan akad murabahah adalah produk pembiayaan konsumtif unggulan di Bank Syariah Indonesia dan menjadi salah satu penyumbang terbesar dalam pendapatan bank. Penelitian ini dilakukan untuk mengetahui karakteristik margin KPR syariah dan faktor yang memengaruhi pendapatan margin murabahah pada produk KPR syariah. Model yang digunakan adalah regresi linear berganda dengan metode OLS. Hasil penelitian menyimpulkan bahwa volume pembiayaan murabahah dan inflasi tidak berpengaruh signifikan terhadap pendapatan margin murabahah. Non performing financing (NPF) berpengaruh negatif signifikan terhadap pendapatan margin murabahah. Biaya operasional per pendapatan operasional (BOPO), BI rate, growth, dan dummy merger berpengaruh positif signifikan terhadap variabel pendapatan margin murabahah. Bank Syariah Indonesia harus memperhatikan variabel- variabel terkait dengan pendapatan margin murabahah karena merupakan penyumbang pendapatan terbesar., Islamic mortgage financing with a Murabaha contract is the leading consumer financing product at Bank Syariah Indonesia and is one of the largest contributors to bank income. This research was conducted to find out the margin characteristics of Islamic mortgages and the factors that influence the murabaha margin income in the Islamic mortgage product. The model used is multiple linear regression with the OLS method. The result of this research concludes that murabaha's financing volume and inflation have no significant effect on murabaha's margin income. Non-performing financing (NPF) has a significant negative effect on murabaha's margin income. Operational efficiency ratio (BOPO), BI rate, and growth have a significant positive effect on variable income margin murabaha. The findings in this research are the effect of BOPO, NPF, BI Rate, growth, and dummy merger on murabaha margin income. Bank Syariah Indonesia must pay attention to variables related to murabaha margin income because they are the largest contributor.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
