Abstract

This study aims to calculate the level of banking efficiency that needs to be known to be associated with the performance of the banking management macro and micro variable. So banking industry in practice can arrange a program to increase efficiency and to anticipate the influence of anything that can makes banking will be lost .Bank with a good the efficiency in general is able to provide good service for customer. Efficiency of bank usually set pricing with the form of the high interest margin .The variables input used in this research is amount of labor .And the output to calculate efficiency are interest income of the money and the amount of funds which has been distributed. Then, comparing two different principle banking between bank syariah mandiri and bank mandiri. By using the method of measurement efficiency with DEA CCR, in two banks was efficient in some specified time. And then using DEA aggressive appears that the efficiency that tends to look the differences between DMU from both banks. From the, observation bank Syariah mandiri is much better because it can reach effieciency 12nd DMU. If calculating unefficiency that bank syariah mandiri also is better than bank mandiri.

Abstract

This study aims to prove and to use the multiple regression analysis methods can be developed into Poisson regression because the total data follows the assumption of a Poisson distribution. Conditions that occur in poisson regression obtained a global regression coefficient value, which means that each observation point has generalized observation characteristics influenced by the same variables. Based on this problem, a spatial regression is developed where the geographical weighting that called geographically weighted Poisson regression. The results obtained in the geographically weighted poisson regression method allow for variables that have an effect at all observation points. So developed by geographically weighted Poisson regression semiparametric method. This method is implemented in solving the problem of maternal mortality in East Java which is thought to be influenced by the some independent variables. In this study, using East Java data in 2019. The results of mixed geographically weighted poisson regression results, with kernel function used in the analysis is fixed gaussian and the variable number of health facilities was used as a global variable, and obtained 12 groups with local variables that both had a significant effect

Abstract

This research was motivated by an Infrastructure Company which became the focus that several sectors experienced a decline in stock prices, financial performance and economic growth in Indonesia due to the Covid-19 pandemic outbreak. Therefore, to collect empirical data about the impact of investment decisions, leverage, profitability, and activity ratios on price book value in Infrastructure Companies listed on the IDX in 2020, the researchers raised issues and factors that are expected to have an impact on the book price or value. company (PBV). This study use a quantitatives approach and the type of associatiive research. Because the data is secondary, it is obtained from the annual financial reports of infrastructure companies that will be listed on the IDX in 2020 through the IDX's official website. The sample of this study includes 40 annual financial statement data, and multiple regression analysis is used to analyze the data. Leverage is one of the variables which according to the test results have an effect on Price Book Value, while investment decisions, profitability, and activity ratios have no effect on Price Book Value.

Abstract

Munculnya penurunan tingkat FDR BUS bermula pada 2016 hingga 2020 yang ditengarai oleh pengurangan intensitas pembiayaan untuk meminimalisir pembiayaan macet memiliki imbas pada tidak tercapainya fungsi intermediasi bank meskipun likuiditas bank dalam keadaan baik. Demi meminimalisir munculnya risiko likuiditas, maka diperlukan suatu studi mengenai faktor-faktor yang memiliki pengaruh pada FDR yang dapat menghambat bank dalam pemenuhan kewajiban jangka pendeknya. Penelitian pada beberapa indikator keuangan yang dianggap memiliki dampak seperti CAR, DPK, NIM, ROA, NPF, serta inflasi dilakukan guna dapat mengetahui indikator keuangan mana saja yang dapat berpengaruh pada FDR bank. Penelitian ini dilakukan secara kuantitatif asosiatif menggunakan teknik sampling purposive sampling dari data sekunder berupa data laporan keuangan BUS pada tiap-tiap triwulan selama tahun 2016 hingga 2020 yang dianalisis dengan regresi data panel yang dibantu dengan software EViews. Hasil analisis membuktikkan bahwa setidaknya terdapat salah satu variabel di antara CAR, DPK, NIM, ROA, NPF dan Inflasi ini memiliki pengaruh secara serentak. Sementara secara parsial, hanya terdapat dua variabel yakni CAR dan DPK saja yang menghasilkan pengaruh signifikan pada FDR.

Abstract

Kegiatan pengabdian ini didasarkan dengan tingkat pemahaman yang dimiliki oleh mahasiswa program studi akuntansi syariah di UIN Sayyid Ali Rahmatullah Tulungagung mengenai ruang lingkup akuntansi syariah relatif rendah. Di samping itu, pemahaman mahasiswa tentang analisis data statistik juga cenderung rendah. Sehingga hal ini menjadi persoalan khusus ketika mahasiswa melaksanakan penelitian kuantitatif. Maka perlu dilakukan kegiatan ini guna meningkatkan pemahaman mahasiswa secara lebih mendalam. Dalam kegiatan yang diikuti oleh 30 peserta mahasiswa akuntansi syariah tersebut dipaparkan dalam bentuk presentasi secara mendalam mengenai apa saja yang ada dalam ruang lingkup penelitian kuantitatif untuk riset akuntansi syariah serta metodologi penelitian kuantitatif. Tidak hanya itu saja, dalam kegiatan juga dijelaskan secara lebih mendalam mengenai software statistika dan teknik analisis data yang sering digunakan dalam analisis. Dengan demikian, maka akan menjadi bekal yang baik bagi mahasiswa untuk melaksanakan penelitian. Kegiatan tersebut juga terukur pengujian efektifitas berdasarkan nilai pre-test dan post-test. Dengan taraf signfikansi 5%, menunjukkan hasil bahwa kegiatan pengabdian terlaksana secara efektif dimana terdapat peningkatan kemampuan mahasiswa sebelum dan sesudah dilaksanakan kegiatan pengabdian.
