Abstract

The objective of this research is to construct an optimum investment portfolio of courier services sector stocks during period 2018-2021 using Modern Portfolio Theory model and to analyse risk and return generated by optimal portfolio before and after Covid-19 using R programming. Furthermore, we would also examine the impact of the Covid-19 on stock prices before and after Covid-19 to formulate investment decisions. The sample are 5 biggest courier services stocks (by market capitalization) that are listed consistently and did not stock split or reverse stock and the number of observations in 4825 stocks prices during the period January 2018 to October 2021. Based on the result of optimum investment research, we can observe that the best performing stocks with high tangency is AMZN, in fact way ahead of other sample emitens.  The result will be expected to help investors to bid the best possible portfolio in courier services.

Abstract

In order to prevent money laundering and terrorism financing, it is critical for banks to develop an effective mechanism to detect suspicious transactions. Nowadays, one of the most widely developed methods is machine learning. This article aims to discuss the best algorithm model in machine learning to detect possibilities for Suspicious Financial Transactions in XYZ Bank. The machine learning method used is supervised machine learning, with three models compared: Decision Tree, Gradient Boosting, and Random Forest. The tool used is The Konstanz Information Miner (KNIME). According to the findings of the study, the best model for detecting the possibility of SFT in bank XYZ is random forest with an accuracy rate of 99,98%. Based on this level of accuracy, this study reveals that a machine learning approach using historical company data makes a significant contribution to XYZ bank in detecting Suspicious Financial Transactions.

Abstract

A going concern audit opinion is an opinion given by the auditor stating whether there is doubt about the entity's ability to continue as a going concern. Going concern problems are complex and continue to exist, so factors are needed that are used as benchmarks in determining a company's going concern status. This research aims to examine the influence of the audit committee, company size, audit tenure, and KAP reputation about current audit opinions. The subjects of this research are trading, service, and investment companies listed on the Indonesian stock market. The sampling method used a purposive sampling technique for 183 companies. The data in this research was collected through non-participant observation methods by downloading data from the IDX. The results of hypothesis testing show that the variables company size and KAP reputation do not affect going concern audit opinion, while the variables audit committee and audit tenure have a significant effect on going concern audit opinion.

Abstract

Permasalahan utama dalam pengelolaan hipertensi adalah rendahnya kepatuhan pasien terhadap terapi, terutama pada pasien dengan polifarmasi, yang disebabkan oleh kompleksitas regimen obat, risiko interaksi, efek samping, serta kurangnya pengetahuan dan dukungan sosial yang efektif. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang mempengaruhi kepatuhan pasien hipertensi dalam konteks polifarmasi dan merumuskan strategi intervensi yang efektif untuk meningkatkan kepatuhan dan hasil terapi. Metode narrative review digunakan dengan menganalisis penelitian relevan selama lima tahun terakhir dan dianalisis menggunakan model Miles dan Huberman. Hasil menunjukkan bahwa pengetahuan yang baik, dukungan keluarga, komunikasi efektif dengan tenaga kesehatan, penyederhanaan regimen melalui fixed-dose combination, dan pemanfaatan teknologi seperti aplikasi pengingat obat dapat meningkatkan kepatuhan pasien. Meski polifarmasi menimbulkan hambatan akibat efek samping dan kompleksitas, intervensi edukasi dan monitoring farmasis terbukti mengoptimalkan pengelolaan terapi. Implikasi penelitian ini menegaskan pentingnya pendekatan multidisipliner dan penggunaan teknologi digital serta peran aktif farmasis dan dukungan keluarga untuk meningkatkan efektivitas pengobatan dan kualitas hidup pasien hipertensi dengan polifarmasi.

Abstract

This research aims to analyze the impact of GRIT and Motivation to learn on student achievement in economic subjects and to assess the role of gender as a moderating variable. This study used a survey method with a quantitative approach. The population in this study were grade X students in Purworejo Regency, Cluster random sampling obtained a sample of 142 students data collection techniques using questionnaires and tests. Data were analyzed using the IBM SPSS Version 25 application with hypothesis testing and the Moderated Regression Analysis (MRA) test. The results showed a significant impact of GRIT and learning motivation on learning achievement (â= 0.267, t-count = 2.864, p = 0.005), (â= 0.288, t-count = 3.092, p = 0.002). Furthermore, gender as a moderating variable can moderate and strengthen the impact of GRIT and learning motivation on learning achievement. The novelty of this study was the existence of GRIT variables tested on students (especially economics students), while other studies used Grit on employees and teachers. The results of this research could contribute to shaping the behavior of students with high strength, resilience, and motivation during economics learning to maximize the resulting learning achievement.
