Abstract

The purpose of this study was to analyze the effect of soybean soaking time on the quality of tempeh as a mendoan ingredient, especially in terms of taste and texture. Mendoan tempeh has unique sensory characteristics that are largely determined by the quality of tempeh in the initial stages of processing, so that the soybean soaking process is an important factor that needs to be studied scientifically. The research method/approach used was an experimental method with a completely randomized design, where the treatment was a variation of soybean soaking time for 8 hours, 12 hours, and 16 hours. Data were obtained through organoleptic tests using a hedonic scale on the taste and texture of mendoan tempeh, involving untrained panelists, then analyzed using analysis of variance (ANOVA) with the help of SPSS software. The results of the study showed that variations in soybean soaking time had a significant effect on the quality of taste and texture of tempeh as a mendoan ingredient. The 12-hour soaking time produced the highest preference value for both sensory parameters compared to other treatments. The conclusion of this study confirms that controlling the soaking time of soybeans is a crucial initial stage in producing optimal quality tempeh for processed mendoan, and has the potential to become a technical reference for traditional food business actors in improving product quality.

Abstract

This article discusses the Solow-Romet theory of economic growth, aiming to explain the relationship between household poverty in the Province of Daerah Istimewa Yogyakarta (DIY) through investments in education, quality of life improvement, and health. The study examines various influence variables, including Non-Formal Education (XNF), Educational Scholarships (XBS), Protein Consumption (PK), Disease Prevention Costs (XL), Calorie Consumption (IK)), Health Insurance Variables (XAS ), and Food Security (XT) in assessing the poverty status of households in the Special Region of Yogyakarta in 2021. The estimation model employs a logit mode approach, using data from Susenas (National Socioeconomic) data for the Special Province of Yogyakarta, with a sample size of 4044 households. The findings of this study indicate that investments in non-formal education, school fees, and educational scholarships do not significantly affect family poverty status. However, increased investment in quality of life (such as calorie consumption) and health (including disease prevention and health insurance spending) will affect the poverty status of households in the Special Province of Yogyakarta in 2021.

Abstract

Sharia governance constitutes a fundamental pillar in ensuring the legitimacy, credibility, and sustainability of Islamic financial institutions (IFIs). Unlike conventional governance frameworks, Sharia governance integrates corporate governance principles with Islamic jurisprudence, aiming to ensure that all financial activities comply with Sharia principles. As the global Islamic finance industry continues to expand, particularly in Muslim-majority countries such as Indonesia, Malaysia, and Gulf Cooperation Council (GCC) states, the effectiveness of Sharia governance practices has become a critical concern for regulators, practitioners, and scholars. This study aims to systematically review and synthesize existing literature on Sharia governance practices in Islamic financial institutions using a qualitative systematic literature review and conceptual approach. The review draws on peer-reviewed international and national journal articles, regulatory documents, and institutional reports published over the last two decades. The analysis focuses on key components of Sharia governance, including the role of Sharia Supervisory Boards (SSBs), internal Sharia audit mechanisms, governance disclosure, and regulatory frameworks established by standard-setting bodies such as the Accounting and Auditing Organization for Islamic Financial Institutions (AAOIFI) and the Islamic Financial Services Board (IFSB). The findings indicate that while formal Sharia governance structures have been widely adopted, their implementation varies significantly across jurisdictions due to differences in regulatory enforcement, institutional capacity, and scholarly interpretation of Sharia principles. Empirical evidence from Indonesia demonstrates rapid growth in Islamic financial assets exceeding IDR 1,028 trillion in 2025 yet highlights persistent challenges related to SSB independence, effectiveness, and governance transparency. This study contributes by offering a comprehensive conceptual understanding of Sharia governance practices and identifying key gaps between regulatory expectations and operational realities. The findings are expected to provide insights for policymakers, regulators, and Islamic finance practitioners seeking to strengthen Sharia governance frameworks and enhance institutional accountability.
