Abstract:This study examines how a non-diasporic public in the Global South engages with a foreign election in which it holds no vote, no residence, and no direct material stake. Rather than asking how Indonesian netizens represent…
nt Zohran Mamdani, the first Muslim Mayor of New York City, it asks what talking about Mamdani does for these netizens as members of their own polity, and develops the concept of comparative civic imagination: the use of a foreign political figure as a discursive instrument for evaluating, criticising, and re-imagining one’s own democracy. The study applies qualitative Computer-Mediated Discourse Analysis (CMDA) to public Indonesian-language discourse about Mamdani on platform X between 1 November 2025 and 30 June 2026, drawing on a purposively constructed corpus of 213 units—134 citizen-account units as the analytical core and 79 media-account units as contextual triangulation—recoded by comparative function and affective register rather than by stance toward the figure. The findings show that Indonesian netizens engage Mamdani through a comparative architecture organised by the vernacular frame “Mamdani Indonesia” (45% of citizen units) and enacted through three repertoires: analogical personification, institutional benchmarking, and counterfactual transposition. The discourse is animated by civic despair—crystallised in the idiom “Indonesia could never”—which operates as a participatory rather than an apathetic affect, while a domestic value-compatibility filter of doctrinal, sectarian, and purity tests renders the admired model discursively non-transferable, closing a recursive loop theorised here as a digitally networked spectre of comparisons. The article shifts the analysis of transnational digital engagement away from cosmopolitan and diasporic assumptions toward the vicarious engagement of non-diasporic publics, re-theorises despair as a mode of civic engagement, and recovers Benedict Anderson’s spectre of comparisons for platform-era political communication in the Global South.
Abstract:Arabic morphology constitutes a fundamental branch of classical Arabic linguistics, focusing on morphological word transformation (tashrif) and derivational morphology. Despite more than a millennium of development, epistemological…
temological inquiry into ilmu sharaf — concerning its sources of knowledge, methods of rule formation, and scientific validity — remains considerably limited in contemporary academic literature, with existing studies tending toward normative and pedagogical orientations that neglect its fundamental philosophical dimensions. This article aims to examine the epistemology of ilmu sharaf from the philosophy of science perspective, tracing its historical genealogy from the early Islamic codification period through to modern Arabic linguistics, and analyzing its contributions to contemporary Arabic morphology. The research employed a qualitative library research method with historical, epistemological, and comparative-linguistic approaches, utilizing critical analysis of relevant primary and secondary sources. The findings reveal that ilmu sharaf possesses a robust epistemological foundation derived from the Qur'an, hadith, classical Arabic fushah poetry, and qiyas (analogical reasoning), and was developed through the methods of sima' (documentation), istinbath (inference), and ta'lil (rational justification) by linguists of the Bashrahn and Kufahn schools. Ontologically, its subject matter is morphological word transformation that produces semantic change; axiologically, it functions to preserve Arabic linguistic purity and facilitate Qur'anic comprehension. The contributions of ilmu sharaf to modern Arabic linguistics are demonstrably significant, particularly in the development of root-and-pattern morphology theory, derivational semantics, and Arabic natural language processing (NLP). These findings indicate that the classical sharaf tradition is not merely historically relevant but also carries important methodological implications for contemporary Arabic computational linguistics.
Abstract:This study proposes a linear regression-based intelligent calibration approach to improve the accuracy of water turbidity sensor readings in an Arduino microcontroller-based embedded system. The primary objective of this…
research is to develop a mathematical model capable of converting analog values from the Analog-to-Digital Converter (ADC) into a numerical representation that reflects the actual water turbidity level in Nephelometric Turbidity Units (NTU). The calibration process was performed using a standard Hanna Turbidity Meter with water samples ranging from 0.56 NTU to 500 NTU. Measurement results demonstrated a strong linear relationship between the ADC value (495–686) and NTU, with an average system accuracy level above 90%. Comparison of sensor measurements with the standard instrument showed an error margin below 5%, confirming the reliability of the linear regression model in compensating for optical sensor nonlinearities.
Abstract:Nori is a seaweed-based food that is favored by the Indonesian people, but its availability is still limited. Meanwhile, the abundant production of land kale (Ipomoea reptans) as a local vegetable has not been optimally…
utilized, resulting in low economic value and its potential as a food source has not been maximized. One solution to overcome this problem is to use organic land kale as an alternative ingredient for making nori. Organic land kale is known to have good nutritional content and is commonly consumed by the community. This study aims to determine the level of acceptance of analog nori made from organic land kale as a healthy snack through organoleptic tests. The method used was an experiment with a completely randomized design (CRD), consisting of 24 samples, 6 treatments, and 4 repetitions. The treatment given was carrageenan concentration (0%, 0.6%, 0.8%, 1%, 1.2%, and 1.4%) Data were analyzed using the Friedman Test to assess panelists' preferences for taste, color, aroma, and texture parameters. It can be concluded that the results show the addition of carrageenan at 1% produces analog nori with the highest level of acceptance, so it is considered the most optimal formulation.

role of spiritual intuition (kashf), the use of analogy and metaphor, and the influence of Sufi order (tariqa) teachings and practices. The article also highlights figures such as Al-Qushayri, Al-Tirmidhi, Ibn Arabi, Al-Ghazali, Junayd al-Baghdadi, and Abu 'Abd al-Rahman al-Sulami, as well as major Sufi orders like Chishti and Qadiri. Through an analysis of examples of Hadith interpretations, this research demonstrates the significance and unique contribution of Sufi Hadith hermeneutics to the understanding of Islamic spirituality, while also identifying contemporary issues and academic debates related to these methods. The conclusion of this research underscores the richness and complexity of Hadith hermeneutics within the Sufi tradition, as well as its relevance in the broader context of Islamic studies.
Abstract:Signal interference or noise is one of the main problems in data transmission that can reduce information quality in both analog and digital systems. This study aims to visually analyze the effects of noise using audio software.…
oftware. The method used is simulation-based, where a pure signal is used as an initial reference before being subjected to various levels of interference. The analysis results show that in analog signals, noise causes permanent waveform distortion that is difficult to recover. In contrast, digital signals tend to maintain data integrity as long as the interference does not exceed a certain threshold. These differences in signal characteristics can be visually observed through waveform displays in the software. The results indicate that digital systems have advantages in maintaining signal quality in noisy environments and have the potential to be used as educational media for basic telecommunication and signal processing studies.
