Abstract

This study aims to analyze the role of audit evidence quality in improving the credibility of financial statements based on the perspective of agency theory, assurance theory, and legitimacy theory. This research employs a literature review approach using the Systematic Literature Review (SLR) method, utilizing secondary data sourced from relevant books and journal articles published between 2017 and 2025. The results of the study indicate that the four dimensions of audit evidence quality, relevance, reliability, timeliness, and sufficiency, play a significant role in enhancing the reliability of the audit process and the credibility of financial statements in the eyes of stakeholders. Relevance is influenced by the type of findings and audit objectives, reliability is determined by objectivity and external sources of evidence, timeliness is related to the appropriate reporting period, while sufficiency depends on the level of risk and complexity of the transaction. High quality evidence reflects the auditor's independence, professionalism, and compliance with standards and codes of ethics, thereby strengthening public trust in the integrity of financial information. Thus, the quality of audit evidence is not only technical, but also an important instrument in maintaining the company's legitimacy and credibility in front of stakeholders

Abstract

This study develops a Susceptible–Exposed–Infectious–Recovered (SEIR) mathematical model with two time-dependent optimal control strategies educational campaigns and medical treatment to analyze Ebola transmission. The nonlinear system is examined using Pontryagin’s Minimum Principle, and the optimality system is solved numerically through the Forward–Backward Sweep Method in MATLAB. Simulation results show that combined controls substantially reduce the peak number of infected individuals, decrease cumulative infection cases, and shorten the epidemic duration compared to the uncontrolled scenario. Early implementation of both interventions further improves epidemic suppression and reduces the overall cost functional value. These results demonstrate the effectiveness of integrated control strategies and highlight mathematical modeling as a decision-support tool in public health planning.

Abstract

Abstract; Psychological well-being (PWB) has become a central issue in modern society, which is experiencing an increase in mental disorders due to the absence of values ​​and the loss of traditional life guidance. This study examines the concept of well-being from a Sufi perspective through the thoughts of Haji Abdul Malik Karim Amrullah (Hamka), a renowned Indonesian cleric and intellectual. The research was conducted qualitatively and descriptively, employing a literature study approach, with Hamka's three main works on Sufism serving as primary sources. The analysis was conducted by adopting Carol D. Ryff's Psychological Well-being (PWB) model, which comprises six dimensions: self-acceptance, positive relationships with others, autonomy, environmental mastery, life purpose, and personal growth. The results of the study show that Hamka's Sufi thoughts are not only relevant to the dimensions of modern Positive Well-being (PWB) but also offer a synthesis between Islamic spiritual values and the psychological needs of contemporary humans. These findings emphasise the importance of integrating religious and psychological approaches in building human well-being as a whole, especially in the context of Islam and Indonesia. Keywords: Hamka's Thoughts; Modern Sufism; Psychological Well-Being.   Abstrak; Kesejahteraan psikologis (psychological well-being/PWB) menjadi isu sentral di tengah masyarakat modern yang mengalami peningkatan gangguan mental akibat kekosongan nilai dan hilangnya panduan hidup tradisional. Studi ini menelusuri konsep well-being dalam perspektif tasawuf melalui pemikiran Haji Abdul Malik Karim Amrullah (Hamka), seorang ulama dan intelektual besar Indonesia. Penelitian dilakukan secara kualitatif-deskriptif dengan pendekatan studi pustaka, menggunakan tiga karya utama Hamka tentang tasawuf sebagai sumber primer. Analisis dilakukan dengan mengadopsi model PWB Carol D. Ryff yang meliputi enam dimensi: penerimaan diri, hubungan positif dengan orang lain, otonomi, penguasaan lingkungan, tujuan hidup, dan pertumbuhan pribadi. Hasil penelitian menunjukkan bahwa pemikiran tasawuf Hamka tidak hanya relevan dengan dimensi-dimensi PWB modern, tetapi juga menawarkan sintesis antara nilai-nilai spiritual Islam dan kebutuhan psikologis manusia kontemporer. Temuan ini menegaskan pentingnya integrasi pendekatan religius dan psikologis dalam membangun kesejahteraan manusia secara utuh, khususnya dalam konteks keislaman dan keindonesiaan. Kata Kunci: Pemikiran Hamka; Psycological Well-Being; Tasawuf Modern
