Abstract

Suppose is a special symmetric matrix of order 6×6 with integer powers, where the entries are real number elements. To obtain the general form of the trace of the matrix by determining the general form of the matrix A_n^6 where the rank of the matrix is ​​first sought from the power of two to eleven and the power of negative two to negative eleven. Then guess the general formula for the exponent of the matrix with positive integer powers which is proven by mathematical induction and with the same steps guess the formula for the exponent of the matrix with negative integer powers which will be proven by the matrix inverse rule. So that the result is obtained, namely the general form of the trace of the matrix and is proven by the definition of trace along with examples of applications of the trace matrix.

Abstract

This study aims to analyze the authority of BMT in managing Islamic Social Finance (ISF) based on Indonesian regulations, specifically Law No. 23 of 2011 on Zakat Management and Law No. 41 of 2004 on Waqf. This qualitative research employs a juridical-normative approach and is categorized as field research. Primary data were obtained through field interviews, and data analysis was conducted descriptively. The findings reveal that although BMT has an organizational structure with a māl manager separating the management of baytūl māl and baytūl tamwīl, the prevailing regulations do not grant BMT authority to manage ISF, including zakat and cash waqf. However, in practice, BMT still plays a role in ISF management as a representative of Zakat Management Institutions (LAZ) and nazir for waqf. Zakat management is carried out in collaboration with LAZIZMU and LAZ Timoho Sejahtera, while cash waqf management involves partnerships with Islamic Financial Institutions as Waqf Recipients (LKS-PWU). Supervision of ISF management in BMT is conducted by the Sharia Supervisory Board (DPS), which provides general guidelines based on sharia principles and regulations, and by the Cooperative Office through regular reporting to ensure compliance with laws. These findings highlight the practice of ISF management by BMT despite being restricted by current regulations.

Abstract

Penelitian ini dilakukan di PD. COMBOT KIDS, dengan tujuan untuk menganalisis pengaruh Absensi, Gaji dan Insentif terhadap Omzet penjualan. Penelitian ini menggunakan data sekunder yang bersumber dari laporan keuangan PD. COMBOT KIDS dan menggunakan skala Rasio. Teknik analisis data yang digunakan meliputi Uji Normalitas, analisis regresi linier berganda, uji t, uji F, dan koefisien determinasi dengan bantuan IBM SPSS Statistics versi 25. Hasil penelitian menunjukkan bahwa secara parsial absensi tiak berpengaruh terhadap omzet penjualan, secara parsial gaji berpengaruh positif dan signifikan terhadap omzet penjualan, serta insentif berpengaruh positif dan signifikan terhadap omzet penjualan. Kemudian secara simultan absensi, gaji, dan insentif berpengaruh positif dan signifikan terhadap omzet penjualan. Nilai koefisien determinasi sebesar 54% menunjukkan bahwa omzet penjualan dapat dijelaskan secara kuat oleh ketiga variabel independen dalam penelitian ini.

Abstract

The purpose of this study is to analyze the effect of ROE on company value in the JII group for the 2019-2021 period. Using a quantitative approach to analyze the relationship between ROE and company value as measured by the PER in companies in the JII for the 2019-2021 period. The analysis techniques used include multiple linear regression tests, t-tests, coefficient of determination (R²) tests, and correlation tests to measure the strength of the relationship between variables. The results show that ROE has a significant and positive effect on company value, with most of the PER variability explained by ROE. The results of the analysis show that ROE has a significant and positive effect on company value as measured by PER. Companies with high ROE, such as Unilever Indonesia and Indofood CBP, have high PERs, reflecting investor confidence in the prospect of profit growth. Conversely, companies with lower ROEs such as Vale Indonesia have lower PERs, indicating a more cautious market view. Although ROE has a strong influence, other factors such as macroeconomic conditions, industry prospects, and sharia compliance also affect company value.
