Abstract

Telah dilakukan penelitian mengenai Konstruksi Dasar Prototipe Elektroda Luas Permukaan Efektif untuk Meningkatkan Produksi Energi Listrik dari Air Lindi Menggunakan Teknologi Microbial Fuel Cell. Modifikasi elektroda dilakukan terhadap elektroda anoda yang terpapar langsung ke substrat (air lindi). Sebagai pembanding juga disiapkan anoda berbentuk pelat. Masing-masing diterapkan pada sel microbial fuel cell (MFC) membentuk dua varian MFC, MFC elektroda GL-GL (anoda pelat) dan MFC elektroda LPE-GL (anoda termodifikasi). Dari hasil pengukuran memperlihatkan kenaikan nilai tegangan listrik pada MFC elektroda LPE-GL lebih fluktuatif dibandingkan dengan MFC elektroda GL-GL. Selain itu MFC elektroda LPE-GL beberapa kali mencapai nilai tegangan maksimum yang lebih tinggi dari MFC elektroda GL-GL. Hal ini menunjukkan bahwa elektroda anoda termodifikasi berpotensi untuk diteliti bagi pengembangan lebih lanjut.

Abstract

This article discusses the tendency of Tafsīr 'Ilmī in Imam Suyuti's interpretation of the plague verses. Interestingly, as a classical commentator, he interprets the plague verses in his commentary books using the traditions of the Prophet (naqli), but he explains about the plague in addition to his commentary books by referring to the interpretation of the plague verses which are supported by scientific data. To analyze the tendency of this interpretation (ittijāh al-tafsīr), the researcher uses the theory of scientific interpretation. This research is qualitative in nature and uses content analysis methods, especially the istiqra (inductive) method. The istiqra method is used to analyze his interpretation of the plague verses that are spread in his commentaries and his books on epidemics and medicine. The purpose of this study is to reveal the indications of the trend of scientific interpretation explored by Imam Suyūt}ī in his books on epidemics and medicine by referring to his interpretations in his commentary books, so this research is urgent to confirm the historical roots and dynamics of Tafsīr 'Ilmī, whose epistemological tendency has emerged in the era of classical scholars. The results of this study are, first, in general, the method of interpretation of Imam Suyūt}ī is bi al-ma'ṣūr. Second, Imam Suyūtī's interpretation of the plague verses in Ṭā'ūn and medical themed books tends to 'Ilmi' Tafsir in terms of a more scientific explanation of the narrations that are in accordance with science, medical and socio-historical. Third, the scientific tendency in Imam Suyūt}ī's interpretation is in historical and medical.

Abstract

This study examines the potential of biogas effluent as a source of electrical energy through microbial fuel cell (MFC) technology. The results showed that the one-room MFC produced a maximum voltage of 1302,2 mV, while the two-room MFC with KMnO4 electrolyte reached 1084,3 mV with an electric current of 0,1 mA. Simultaneously, the two-chamber MFC with K2Cr2O4 produced a maximum voltage of 1675,8 mV and an electric current of 0,99 mA. This potential, with electrical voltage values equivalent to commercial batteries, can improve the efficiency of electrical energy generation from organic waste and open up wider application opportunities in using renewable energy sources. Characterization of the MFC substrate showed a decrease in organic matter of biogas effluent with COD values of 500,96 mg/L and BOD of 300,23 mg/L. MFC bacteria from biogas waste were dominated by Gram-positive rod-shaped and Sarcina, except for one Gram-negative isolate of Spirillum.

Abstract

This research aims to reveal Abdul Karim Soroush's Text Hermeneutics as an epistemological solution to the reliability of classical Ulumul Qur'an which gave birth to the contestation of mura>dullah's claim in interpretation when faced with contemporary reality. The type of this research is a literature study, because it relies on non-numerical data. While the data analysis technique used is the Miles and Huberman model. While the data analysis method used is content analysis and linguistic analysis. This research produces three important points. First, by using the hermeneutic theory of al-Qabd} wa al-Bast} (theory of shrinkage and expansion), Soroush shows that the reliability of classical Ulumul Qur'an is not for all times, but it is shrinking and expanding. Interpretation will never be final and demands a fresher dynamism of Ulumul Qur'an according to the demands of the times. Second, mura>dullah's claim on an interpretation under the pretext of the objectivity of interpretation is impossible, because the text has multiple meanings and that is the true will of Allah. Third, the interpretation that is in accordance with muradullah is an interpretation that is methodological (based on theory) even though it produces different meanings and interpretations (interpretive pluralism).

Abstract

This research discusses the understanding of LDK PP. Muhammadiyah regarding the verses of da'wah using the perspective of Maqâsid al-Qur'ân. According to LDK PP. Muhammadiyah, Da'wah based on the verses of the Koran stands on two functions of the Koran, namely message and grace. The use of the term mercy function in this case is very close to one of the terms Maqâsid al-Qur'ân, namely rahmah. Starting from this research problem, the researchers traced the intersection of the two functions with the theory of Maqâsid al-Qur'ân, then the researchers formulated the structure of the Maqâsid verses of da'wah in the LDK PP version. Muhammadiyah. The data analysis methods used are the istiqrâ’ (inductive method) and the muqâranah (comparative method). The inductive method was used to inventory the understanding of da'wah verses as a typical Maqâsid view in the LDK PP version. Muhammadiyah, while the comparative method is used to compare the understanding of da'wah verses of the LDK PP. Muhammadiyah with the formulation of Maqâsid al-Qur'ân. This research produced two findings. Firstly, by using the perspective of Maqâsid al-Qur'ân, secondly, the function of the Qur'anic verses of da'wah in the LDK PP version. Muhammadiyah is the dynamics of the mufassir maqâs}idi version of the Maqâsid formulation of da'wah verses, in the form of maqs}ad al-rahmah and maqsad al-risâlah with their respective derivatives. Second, the dynamics of understanding LDK PP. Muhammadiyah regarding da'wah verses shows two Maqâsid simultaneously, namely theocentric and anthropocentric Maqâsid with renewal in its applicable context.

Abstract

Copper (Cu) pollution from industrial wastewater has emerged as a critical environmental issue due to its toxicity, bioaccumulation, and persistence in aquatic ecosystems. Conventional methods for heavy metal remediation often fail to address the dual challenge of high costs and environmental sustainability, necessitating alternative approaches. This study explores the use of sand-based biofilms for the biosorption of Cu ions, leveraging the natural ability of biofilms to adsorb and immobilize heavy metals. The research focuses on optimizing biosorption conditions, including contact time, initial Cu concentration, and pH, while evaluating the broader impacts on water quality parameters such as Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Dissolved Solids (TDS). The experimental results demonstrated that biosorption efficiency peaked at a contact time of 1 day, an initial Cu concentration of 100 mg/L, and a pH of 8. At these optimal conditions, the biofilm achieved a biosorption capacity of 39.7 mg/L for Cu ions. Moreover, the treatment significantly improved water quality, reducing COD by 77.06%, BOD by 78.92%, and TDS by 30%. The mechanism of biosorption was influenced by the availability of functional groups within the extracellular polymeric substance (EPS) of the biofilm, which provided binding sites for Cu ions. The influence of pH was particularly notable, as it regulated the ionic interactions between Cu2+ and the biofilm matrix. This study not only confirms the effectiveness of biofilm-based biosorption for heavy metal mitigation but also highlights its dual role in reducing organic and inorganic pollutants in wastewater. The use of sand as a substrate for biofilm growth adds an element of scalability and economic feasibility, making it an attractive solution for industrial applications. The findings underscore the potential of this eco-friendly approach to contribute to sustainable wastewater management, addressing both environmental and public health concerns associated with heavy metal contamination. Future research could explore the application of this method for other heavy metals and its integration into existing wastewater treatment systems.

Abstract

Research on the simultaneous application of microbial fuel cells (MFCs) for electricity generation and contaminant reduction in leachate has been conducted. A leachate sample collected from the Puuwatu Final Disposal Site was used as the substrate in an MFC system. The investigation included measuring the electrical power generated by the MFC and analyzing contaminant levels in the leachate. The MFC was designed in a dual-chamber configuration with two oxidizing agents, KMnO4 and K2Cr2O7. Six MFC cells were prepared for each treatment and evaluated based on the electrical power generated. During the first 3–5 days of incubation, both MFCs using KMnO4 and K2Cr2O7 showed a significant increase in electrical power. The MFC using KMnO4 reached a maximum electrical power of 556.52 μW on day 4, whereas the MFC using K2Cr2O7 reached a maximum of 385.40 μW on day 5. After 50 days of MFC operation, the leachate showed reductions in COD, BOD, C-organic, N-organic, C/N ratio, and TSS, accompanied by an increase in pH. The removal percentages for COD, BOD, C-organic, and N-organic were 51.7%, 93.1%, 69.5%, and 2.0%, respectively. Comparison with the applicable quality standards indicated that, despite a reduction in contaminant levels after MFC treatment, the leachate still required further treatment to meet the standards.
