Penurunan COD dan TSS pada Limbah Greywater Menggunakan Metode Elektrokoagulasi: Indonesia
No full textDomestic activities at the ITERA TB 2 student dormitory generate greywater containing significant levels of Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS), alongside specific pH levels. The direct discharge of this untreated wastewater poses a severe threat to local ecosystems. To address this issue, this study investigates electrocoagulation—an electrically-driven coagulation process—as an alternative treatment method to mitigate pollutant concentrations. The research evaluated the reduction of COD and TSS (dependent variables) across varying applied voltages (10, 20, and 30 V) and contact times (30, 60, and 90 minutes) as independent variables. The results indicated that the optimum treatment occurred at 30 V with a 90-minute contact time. Under these conditions, COD was successfully reduced from 115 mg/L to 11.5 mg/L, and TSS decreased from 103 mg/L to 9.5 mg/L, accompanied by a pH shift from 7.11 to 9.3. These findings demonstrate the efficacy of the electrocoagulation method in significantly reducing greywater pollutants.Kegiatan domestik mahasiswa yang tinggal di asrama TB 2 ITERA menghasilkan limbah greywater. Limbah greywater mengandung beberapa parameter kualitas air seperti pH, total suspended solid (TSS) dan chemical oxygen demand (COD) sebelum dilakukan pengolahan, sehingga apabila limbah greywater ini dibuang langsung ke lingkungan akan menyebabkan kerusakan pada ekosistem lingkungan. Salah satu metode alternatif yang dapat menurunkan kadar pencemar pada limbah greywater asrama TB 2 yaitu elektrokoagulasi. Elektrokoagulasi merupakan proses koagulasi menggunakan arus listrik. Penelitian ini dilakukan untuk menganalisis penurunan parameter COD dan TSS pada limbah greywater asrama TB 2 ITERA menggunakan dua variabel yaitu chemical oxygen demand (COD) dan total suspended solid (TSS) sebagai variabel terikat dan variasi tegangan sebesar 10, 20 dan 30 volt dan variasi waktu selama 30, 60 dan 90 menit sebagai variabel bebas. Hasil dari proses elektrokoagulasi menunjukkan penurunan terbaik terhadap parameter COD dari 115 mg/l menjadi 11,5 mg/l, parameter TSS dari 103 mg/l menjadi 9,5 mg/l dengan nilai pH dari 7,11 menjadi 9,3 pada tegangan sebesar 30 volt dengan waktu kontak 90 menit. Hal ini dapat membuktikan bahwa metode elektrokoagulasi mampu menurunkan kadar pencemar yang terdapat dalam limbah greywater
Exploring the drivers of firm value in the transportation and logistics industry
No full textThis study explores the drivers of firm value in the transportation and logistics industry by examining the influence of capital structure, institutional ownership, and profitability. The research focuses on companies listed on the Indonesia Stock Exchange during 2021–2023 and applies a quantitative approach using secondary data from annual financial reports. Firm value is measured by Tobin’s Q, capital structure by the Debt to Asset Ratio (DAR), institutional ownership by the proportion of institutional shareholding, and profitability by Return on Equity (ROE). Multiple linear regression is employed as the analytical technique. The findings indicate that capital structure and profitability have a positive effect on firm value, suggesting that well-managed leverage and higher profitability strengthen investor confidence in firm performance. Conversely, institutional ownership does not show a significant effect, implying that a larger proportion of institutional shares does not necessarily enhance firm value. These results emphasize the role of financial management and profitability in shaping firm value within the transportation and logistics industry
The effect of ESG on financial performance of energy sector companies in Indonesia and Malaysia during 2020–2023
No full textThe study seeks to examine how Environmental, Social, and Governance (ESG) disclosure influences financial performance within energy companies in Indonesia and Malaysia from 2020 to 2023. The study utilizes data sourced from annual and sustainability reports of energy firms listed on the Indonesia Stock Exchange and Bursa Malaysia. Multiple linear regression was applied as the analytical technique, with Price to Book Value (PBV) used as the indicator of financial performance. The findings reveal that overall ESG disclosure does not exert a significant impact on financial performance. Nevertheless, when assessed individually, the governance component shows a statistically significant positive effect on PBV. These outcomes offer valuable insights for regulators and companies to strengthen governance practices in ESG reporting to enhance investor appeal and support long-term firm value
Penguatan Literasi Bahaya Zat Adiktif melalui Media Infografis pada Siswa SMA Negeri 2 Banjarbaru: Indonesia
No full textHigh school adolescents are a vulnerable group to exposure to addictive substances due to social and academic pressures, thus requiring literacy-based preventive interventions. This community service program aimed to strengthen students’ literacy regarding the hazards of addictive substances at SMA Negeri 2 Banjarbaru through a chemical literacy-based approach, delivered using educational infographics and participatory learning activities. The program was implemented in a single integrated session consisting of a pre-test, delivery of materials using infographic media accompanied by interactive mini quizzes via Quizizz, a question-and-answer session, and a post-test. A total of 36 students participated in the activity, comprising 12 representatives from each grade level (grades X, XI, and XII). Evaluation results showed an improvement in students’ understanding of addictive substances, as indicated by an increase in the average pre-test score of 66.4 (median 70.0 with score ranged from 30.0 to 100.0) to an average post-test score of 87.5 (median 90.0 with score ranged from 60.0 to 100.0), representing an increase of 21.1 points (31.8%). In addition to quantitative evaluation, brief non-formal interviews with students conducted during and after the activity indicated early signs of changes in students perspectives, particularly in their awareness of adopting healthier and non-addictive coping mechanisms when dealing with academic stress. These findings suggest that infographic-based educational approaches combined with interactive activities are effective in enhancing literacy on the hazards of addictive substances as a foundation for primary prevention among adolescents. To support program sustainability, the educational materials were provided to the school in both printed and digital formats for use in guidance and counseling services as well as school health programs.Remaja usia sekolah menengah atas merupakan kelompok yang rentan terhadap paparan zat adiktif akibat tekanan sosial dan akademik, sehingga memerlukan intervensi preventif berbasis literasi.

Western Colonialism in the Muslim World: A Historical Analysis of the Forms and Mechanisms of Domination: Kolonialisme Barat terhadap Dunia Islam: Analisis Historis atas Bentuk dan Mekanisme Dominasi
No full textThis study examines the historical background as well as the forms and mechanisms of Western colonialism in the Muslim world, emphasizing that the decline of Muslim societies should be understood as a historical and structural phenomenon rather than a consequence of Islamic theological teachings. Following the death of the Prophet Muhammad (peace be upon him), the Muslim world experienced significant political dynamics characterized by internal conflicts, the weakening of the caliphal authority, and the eventual collapse of major political powers such as the Abbasid and Ottoman empires. These conditions created structural vulnerabilities that enabled the penetration of external powers. At the same time, the stagnation of scientific and intellectual development, along with the decline of political support for scholarly traditions, further limited the capacity of Muslim societies to respond to global transformations. Within this context, European expansion into Muslim territories occurred gradually, beginning with the Reconquista in Andalusia, the Crusades, the maritime expansion of Iberian powers, and eventually the emergence of modern colonialism in the nineteenth and twentieth centuries. This research employs a qualitative method with a historical-critical approach based on library research. The findings indicate that Western colonialism was not limited to military and political domination but also operated through administrative and legal control, economic exploitation, educational and cultural restructuring, and the production of ideological and discursive representations of Islam. These processes ultimately formed a complex and long-term system of colonial hegemony that significantly shaped the political, economic, and intellectual structures of Muslim societies.
[Tulisan ini mengkaji latar belakang historis serta bentuk dan mekanisme kolonialisme Barat terhadap dunia Islam dengan menekankan bahwa kemunduran masyarakat Muslim merupakan fenomena historis dan struktural, bukan akibat dari ajaran teologis Islam. Sejak wafatnya Nabi Muhammad SAW, dunia Islam menghadapi berbagai dinamika politik yang ditandai oleh konflik internal, melemahnya institusi kekhalifahan, serta runtuhnya kekuatan politik besar seperti Dinasti Abbasiyah dan Kesultanan Utsmani. Kondisi tersebut menciptakan kerentanan struktural yang membuka peluang bagi penetrasi kekuatan eksternal. Di sisi lain, stagnasi perkembangan ilmu pengetahuan dan melemahnya dukungan politik terhadap tradisi intelektual turut memperlemah kemampuan dunia Islam dalam merespons perubahan global. Dalam konteks tersebut, ekspansi Eropa ke wilayah-wilayah Muslim berlangsung secara bertahap, mulai dari Reconquista di Andalusia, Perang Salib, ekspansi maritim bangsa Iberia, hingga kolonialisme modern pada abad ke-19 dan ke-20. Penelitian ini menggunakan metode kualitatif dengan pendekatan historis-kritis berbasis studi kepustakaan. Hasil penelitian menunjukkan bahwa kolonialisme Barat tidak hanya berlangsung melalui dominasi militer dan politik, tetapi juga melalui kontrol administratif dan hukum, eksploitasi ekonomi, rekayasa pendidikan dan budaya, serta produksi wacana ideologis tentang Islam. Proses tersebut membentuk sistem hegemoni kolonial yang berdampak jangka panjang terhadap struktur politik, ekonomi, dan intelektual masyarakat Muslim.

Strengthening transparency and performance: The role of independent commissioners in enhancing CSR disclosure's impact on firm performance
No full textPurpose – This study examines the effects of corporate social responsibility (CSR) disclosure on firm performance measured by Return on Equity (ROE), while examining the moderating role of independent commissioners in strengthen this relationship.Design/methodology/approach – This research uses data obtained from all publicly listed companies on the Indonesia Stock Exchange, comprising 514 firm-year observations from 2018 to 2022. Employing moderated regression analysis model, the study evaluates the direct and moderating effects within the proposed research framework.Findings – The findings reveal that CSR disclosure is positively and significantly related to the firm performance. In addition, independent commissioners are shown to strengthen the relationship, where more independent and objective supervision increases the effectiveness of CSR and attracts investor confidence.Research limitations/implications – This study aggregates CSR disclosure without differentiating its parts and does not account for the features of independent commissioners, such as knowledge or tenure. Future studies should explore these dimensions and conduct comparative or longitudinal studies to enhance the understanding of CSR's impact on financial performance.Practical implications – This study provides guidance for company management to improve CSR strategies by enhancing the oversight quality of independent commissioners. The findings also suggest that policymakers and professional institutions should focus on strengthening the competence and accountability of board members through evaluation frameworks and training programs, to ensure effective governance in CSR practices and long-term firm performance.Originality/value – This study offers a new perspective by examining the moderating role of independent commissioners in the CSR to financial performance relationship in Indonesia, using a more detailed CSR disclosure measure based on the GRI 2021 framework. It provides practical and academic insights into governance and sustainability in emerging markets
Green Economy Implementation in Indonesia: Legal Frameworks, Policy Challenges, and Implications for Human Rights
No full textThis article examines the implementation of the green economy in Indonesia and analyzes its implications for human rights within the framework of sustainable development. It aims to assess how national green economy policies and initiatives align with human rights principles and to what extent they contribute to inclusive and equitable development. Using a qualitative normative legal research method, the study relies on an analysis of statutory regulations, government policies, international reports, and relevant legal and policy documents, interpreted through a human rights–based approach and sustainable development theory. The findings show that Indonesia has adopted a range of legal and policy instruments supporting the green economy, particularly in the areas of energy transition, carbon pricing, environmental protection, and green investment. These initiatives have the potential to promote key human rights, including the right to a healthy environment, the right to health, the right to development, access to decent work through green jobs, and increased public participation in environmental governance. However, the study also identifies significant challenges in implementation, such as weak law enforcement, limited institutional capacity, insufficient monitoring mechanisms, and uneven inclusion of vulnerable groups, including local communities, women, and indigenous peoples. The analysis suggests that without strong governance, transparency, and accountability, green economy policies risk reproducing social inequalities and undermining human rights objectives. The article concludes that while the green economy offers meaningful opportunities to advance human rights in Indonesia, its success depends on strengthening legal frameworks, ensuring effective implementation, and embedding human rights considerations at every stage of policy design and execution, thereby supporting a just and inclusive transition toward sustainable development
The Supremacy of Peer Inclusion: An AI-Driven Vignette Experiment on Teamwork Dynamics
No full textAbstract: Contemporary teamwork research remains heavily skewed toward leadership styles, often neglecting the horizontal influence of peer behavior. This study challenges the "heroic leader" paradigm by examining the impact of leader behavior (structured vs. open) and member behavior (inclusive vs. exclusive) on individual contributions. We utilized a novel 2 X 2 randomized vignette design, where scenarios were AI-generated to ensure high internal validity and eliminate researcher bias. Analyzing data from 375 participants, the results reveal a critical shift in teamwork theory: individual contributions are significantly driven by peer inclusiveness, whereas leadership styles—and the interaction between variables—yielded no significant effect. These findings suggest that in high-stakes collaborative environments, the "peer climate" overrides formal leadership directives. This research advocates for a paradigm shift in organizational training, moving away from top-down leadership development toward fostering "inclusive followership" as the primary driver of team effectiveness
