Abstract

Double entry bookkeeping (DEB) and the rules of debit and credit (RDC) are first contained in a mathematical book. Using this basic premise, this study develops a mathematics-based teaching model (MBTM) and examines its impact on instructors’ financial accounting performance. This study employed a quasi-experimental method with 43 accounting instructors as participants. The findings indicate that the implementation of the MBTM resulted in a significant improvement in instructors' performance. Furthermore, the teaching experience had a positive effect on instructor performance, particularly when combined with the MBTM approach. Previous empirical research has aimed to compare traditional (preparer) and innovative (user) teaching approaches for the introductory accounting course. In line with this objective, the present empirical study introduces the MBTM as an innovative teaching model and assesses its effectiveness. This study is the first of its kind to implement the innovative mathematics-based teaching model (MBTM) specifically designed based on the history of accounting. It is worth noting that the study also utilized accounting instructors as research subjects, a less commonly employed approach in previous research endeavors.

Abstract

Background: With the rise in green chemistry, the synthesis of antibiotic compounds through enzymatic processes is a preferred option. Penicillin-G acylase (PGA) is an important enzyme for producing important antibiotics, such as penicillin and its derivatives. Therefore, studies on PGA have been conducted worldwide. In the penicillin biosynthetic pathway, PGA catalyzes the conversion of penicillin G into 6-amino penicillanic acid (6-APA), a precursor for the enzymatic synthesis of penicillin derivatives. Unfortunately, bacteria naturally produce PGA in small quantities. Objective: One strategy for producing this enzyme in large quantities is DNA recombination, which is expressed in Escherichia coli. The formation of inclusion bodies (IBs) is a common obstacle to protein overexpression in Escherichia coli. In this study, we discuss IBs solubilization methods for recombinant PGA derived from E. coli (rPGAEc) expressed in E. coli BL21 (DE3). Recombinant E. coli BL21 (DE3) cells harboring rPGAEc were induced with IPTG for enzyme expression. Induction was performed at 16 °C for 4 h and 24 h. The PGA enzyme expressed in the IBs form was then incubated in two solutions containing 8 M urea and 0.2% sarcosine to obtain a soluble enzyme. Results: Based on protein analysis by SDS-PAGE, a solution containing 8 M urea solubilized PGA more abundantly than 0,2% sarcosine. Conclusion: The solubilization technique of PGA expressed by E. coli proposed in this study is an alternative solution that can be considered for this purpose.

Abstract

For Muslim customers, the halal validity of cosmetics is a major concern. In cosmetics industry, one critical aspect is the contamination of porcine derivatives in halal cosmetic products. This review method discusses the application of real-time PCR (RT-PCR) for the detection of porcine DNA in cosmetic products, including the principle of the method, DNA extraction protocol, primers and probes design, and method application in various types of cosmetic products. DNA extraction from the cosmetic matrix samples requires optimization due to the complexity of the material and the possibility of DNA degradation during the cosmetic production process. The precise primers and probes design is also crucial to ensure specificity towards porcine DNA. The application of the RT-PCR method has been successful in various forms of cosmetics such as creams, lotions, lipsticks, and soaps, although each type of cosmetic product has unique challenges. Performance evaluation of the RT-PCR method showed good repeatability and reproducibility with coefficients of variation (CV) below 10% in numerous studies. The main challenges of the method include extraction of DNA due to the DNA degradation during the cosmetics production process, interference from cosmetic ingredients to RT-PCR analysis, and the need for method standardization. Solutions that have been developed such as the use of short gene targets, PCR additives to overcome inhibitors, and amplification techniques such as digital PCR to improve sensitivity. The recent development has led to the integration of protein-based methods and international standardization to support cosmetic halal certifications.

Abstract

The use of natural products has been widely used as a resource of new bioactive chemical compounds. One of them is the Paku Atai Merah (Angiopteris ferox Copel) tuber which has long been used empirically by the Dayak tribe of East Kalimantan as an anti-cancer. The purpose of this study was to determine the anticancer cytotoxic activity of the extract and fractions of Paku Atai Merah tuber against T47D breast cancer cells in vitro. Extract of Paku Atai Merah tubers was obtained by maceration method using ethanol solvent until obtained the ethanolic extract then fractionated using various solvents to obtain n-hexane, ethyl acetate, and aqueous-ethanol fractions. The cytotoxic effect was carried out based on the MTT assay. Phytochemical screening tests showed positive results for the presence of flavonoid, phenolic, tannin, saponin and steroid compounds. The results of the cytotoxic activity study showed that the ethyl acetate fraction had moderate cytotoxic activity in T47D cancer cells with an IC50 value of 84.8 µg/ml. Ethanol extract (513.06 µg/ml) and n-Hexane frsction (881.97 µg/ ml) were also included in the weak category. This study indicates that ethyl acetate fraction can be developed as a supportive therapy for breast cancer treatment.

Abstract

This study examines the internal audit functions at four universities, both public and private, in the Special Region of Yogyakarta, Indonesia, with a focus on their contribution to governance and their role as the organization's third line of defense, as recommended by The Institute of Internal Auditors. Employing a qualitative research approach, the study utilizes descriptive data analysis to assess the effectiveness of internal audits in these institutions. The findings reveal that while the internal audit functions in both state and private universities receive adequate organizational support, they face resource constraints, particularly in state universities that are not yet legally incorporated and private universities with newly established audit functions. The study also highlights the diversity of audit activities, including review and consultation, with more established internal audit units demonstrating greater variety and depth in their assignments. Moreover, the internal audit function emerges as a strategic partner in risk management, effectively serving as the third line of defense through regular coordination and communication with university management. This research underscores the critical role of internal audits in enhancing governance and managing risks within the higher education sector.
