Abstract

The efficiency of generators in a power plant decreases as running duration increases. This can also happen to the generator of the PT. Steam Power Plant. The Semen Tonasa Power Plant is also known as the Boiler Turbine Generator (BTG) Power Plant. BTG II has been operating for approximately 8 years and based on generator operation data, there has been a decrease in the power generated by the genera-tor, when viewed from the power input to the current turbine, compared to the initial operation of this plant. The aims of this study are to assess the value of the real generator efficiency and compare it to the efficiency generator based on its specifications. Data loading is required to ascertain the true value of generator efficiency, as the output power created by the generator and the input power is the power gen-erated by the turbine, which is computed using the enthalpy reduction method. According to the research, the average generator efficiency values for generator units C and D are 91.36 percent and 90.34 percent, respectively, with real average loads of 25,56 MW and 25,08 MW. In comparison to the data standards, generator unit C saw a 6.76 percent drop in efficiency, whereas generator unit D experienced a 7.76 per-cent decrease efficiency. Comparison with the data specifications for generator units C experienced a decrease in efficiency of 6,76% while generator unit D experienced a decrease in efficiency of 7,76%. The efficiency of the generator in unit C decreased 0.85% per year, and unit D was 0.97%.

Abstract

Banking companies face challenges in the transparency of financial risk disclosures, which affects investor confidence and the stability of the banking sector. Effective governance mechanisms are required to enhance accountability and risk mitigation. This research examines and provides empirical evidence on risk monitoring committee characteristics and risk disclosure. The sample is selected through purposive sampling on the banking sector detailed on the Indonesia Stock Exchange (IDX) from 2018 to 2022, yielding 205 observations from 44 companies. The research utilizes secondary data sourced from social media platforms, annual reports, and corporate websites. The data analysis employs multiple linear regression. This research found that gender diversity and the frequency of committee meetings positively influence risk disclosure. Meanwhile, the independent committee and the committee qualifications do not significantly affect risk disclosure. These findings provide a basis for improving corporate governance in Indonesian banks especially risk monitoring committees.

Abstract

The study of hadith in the classical tradition often reflects interpretive patterns shaped by patriarchal constructions, thus marginalizing women’s experiences and voices from religious authority. The lack of methodological studies on the application of Amina Wadud’s feminist hermeneutics to a corpus of hadith considered gender-biased indicates a significant academic gap that needs to be addressed to achieve a more just and inclusive discourse on interpretation. This study aims to describe Wadud’s methodological steps in reading hadith; evaluate her strengths and limitations in interpreting gender-problematic texts; and examine their theoretical and practical implications for the development of hadith studies from a gender-justice perspective. The research method employed is qualitative with a critical-hermeneutical analysis approach, through reading gender-problematic hadith. The results show that Wadud positions gender bias as a historical construct born of patriarchal culture during the period of hadith transmission. She emphasizes the distinction between universal normative texts and culturally contextual interpretations. Using the ethical hermeneutic strategy of the Quran, Wadud reinterprets hadiths on leadership and witnessing, emphasizing egalitarian principles that reject the subordination of women. This approach demonstrates the potential for a more participatory and responsive reinterpretation of the text in the pursuit of gender justice. However, its limitations lie in the potential for interpreter subjectivity and resistance from traditionalists. In conclusion, Wadud’s methodology makes a significant contribution to the development of more contextual, critical, and ethical gender-based interpretations of hadith.

Abstract

The rapid expansion of crypto assets since 2020 has generated complex challenges for Islamic economic law, particularly regarding the coherence of legal norms and fatwas across jurisdictions. Although crypto assets offer economic opportunities, regulatory and juristic responses in Muslim majority countries remain fragmented, reflecting the absence of a standardized maqāṣid al sharīʿah based evaluative framework. This study aims to analyze and compare the legal norms and fatwas governing crypto assets in Indonesia, Malaysia, and the United Arab Emirates during 2020 to 2025 from a maqāṣid-oriented perspective. The research employed a normative comparative legal approach supported by an evaluative simulation model, utilizing secondary data from publicly available regulations, fatwas, and official policy documents. The simulation operationalized key maqāṣid dimensions, namely protection of wealth, protection of intellect, and prevention of harm, across three regulatory scenarios consisting of crypto assets as means of payment, commodities or investment instruments, and objects of zakat. The results show that crypto assets receive higher normative acceptance when positioned as commodities or investment instruments, while their treatment as means of payment and zakat objects remains legally contested. Cross-jurisdictional variations reveal how differing institutional priorities and implicit maqāṣid orientations shape regulatory outcomes. These findings contribute theoretically by demonstrating the applicability of maqāṣid al sharīʿah as an operational evaluative tool in digital finance governance and practically by offering a framework to support the harmonization of fatwas and regulatory policies. Overall, the study highlights the importance of a standardized maqāṣid based approach to enhance legal coherence and certainty in regulating crypto assets within Islamic economic systems. Keywords: Maqāṣid Al-Sharīʿah, Crypto Assets, Legal Norms And Fatwas, Islamic Economic Law, Comparative Legal Analysis.
