Abstract

Penelitian ini bertujuan untuk mengoptimalkan kinerja fotokatalitik ZnO dengan menggabungkan graphene oxide tereduksi (rGO) untuk degradasi metilen biru (MB), pewarna persisten yang umum ditemukan dalam air limbah tekstil. Penelitian ini meliputi sintesis komposit ZnO/rGO, karakterisasi sifat struktural dan optiknya, dan evaluasi efisiensi fotokatalitiknya. Material dikarakterisasi menggunakan XRD, FTIR, spektroskopi Raman, SEM-EDX, dan analisis UV-Vis untuk mengonfirmasi pembentukan komposit dan memeriksa perubahan energi celah pita. Aktivitas fotokatalitik dinilai melalui degradasi MB di bawah iradiasi UV pada dua konsentrasi. Hasilnya menunjukkan bahwa penambahan rGO meningkatkan penyerapan cahaya, meningkatkan transfer elektron, dan mengurangi rekombinasi elektron-lubang dibandingkan dengan ZnO murni. Komposit ZnO/rGO yang mengandung 10% rGO mencapai efisiensi degradasi tertinggi, mencapai 99,1% pada 30 ppm dan 98,9% pada 60 ppm. Temuan ini menunjukkan bahwa rGO secara signifikan meningkatkan sifat struktural dan fotokatalitik ZnO, menjadikan komposit ZnO/Rgo, terutama pada 10% rGO, sebagai material yang menjanjikan dan ramah lingkungan untuk pengolahan air limbah yang terkontaminasi pewarna.

Abstract

This community service program aimed to improve knowledge, perceptions, and behaviors of the Indonesian diaspora at the Sungai Mulia Learning Studio (SBSM) in Kuala Lumpur, Malaysia, regarding the use of traditional spices for health. The program involved counseling, demonstrations, and completion of an evaluation questionnaire using a Likert scale and open-ended questions. Twenty-three participants took part in the activities and evaluations. The results showed high levels of knowledge and positive perceptions, especially in participants’ belief in the health benefits of traditional spices and their understanding of the functions of basic spices such as ginger and turmeric, commonly used as traditional medicines. Although some participants still chose modern medicine as their main option, they demonstrated a positive attitude toward herbal remedies. Behavioral analysis indicated a strong tendency to prepare, consume, and seek information about spices after attending the program. Qualitative findings supported these results; most participants stated that the activities were beneficial, broadened their insight, and encouraged habit changes toward greater use of herbal medicine. All participants also expressed willingness to join follow-up programs. Overall, this program effectively improved spice-based health literacy and has the potential to be scaled up through more intensive practical sessions and provision of guidance materials.

Abstract

Critical thinking skills are crucial for students in the 21st century. Identifying problems, selecting and evaluating them, organizing them, and finding logical solutions are all examples of critical thinking skills. This quantitative descriptive study focused on the Islamic Religious Education Department of the Faculty of Tarbiyah at the Miftahul Huda Institute in Subang. The researchers found that students who took Islamic Religious Education classes had better critical thinking skills. Data were collected using a questionnaire. Problem-based and project-based learning models are two models that can be used to improve students' critical thinking skills. Four indicators of excellent critical thinking were studied, including students' ability to identify and analyze problems, their ability to behave and think critically, and their ability to find creative and logical solutions to real-life problems. Cognitive skills such as critical, creative, and solution-oriented thinking; social skills such as communication, collaboration, and empathy; emotional skills such as self-control, adaptability, and mental resilience; and practical skills such as time management, digital literacy, and entrepreneurship. This curriculum is designed to focus on student performance and incorporate unique courses for each course, as well as life skills. Active learning can be seen in case discussions, projects, and problem-solving. Coaching, mentoring, and collaboration enhance student organization and the campus environment. PAI graduates who develop life skills aligned with Islamic values ​​such as mas'uliyah (responsibility), amar ma'ruf nahi munkar (commanding good and forbidding evil), and istikamah (steadfastness) will be individuals who possess not only academic and spiritual abilities but also flexibility, contribution, and the ability to address contemporary issues.

Abstract

This article discusses the importance of selecting and applying learning models that are relevant to the psychological characteristics and social context of adolescents in the postmodern and digital era. As the internet generation, adolescents require learning approaches that integrate mastery of academic content with character development and critical thinking. Through a conceptual study of the functions, objectives, and principles of national education as mandated by Law Number 20 of 2003, this article emphasizes that the goal of education is to develop Indonesian individuals who are faithful, morally upright, creative, independent, and possess Pancasila-based character. Three learning models—exemplary learning, brain-based learning, and e-learning—are examined within this framework and considered relevant for adolescents. The exemplary learning model positions educators as role models in all aspects of life, not only in the classroom. Brain-based learning emphasizes experiential learning and the optimization of brain function through contextual and meaningful activities. Meanwhile, e-learning offers flexibility and the use of digital technology that aligns with the characteristics of today’s adolescent generation. This study concludes that no single learning model is entirely ideal; therefore, an innovative and collaborative approach that integrates multiple models is necessary to address contemporary challenges and achieve national education goals.

However, conventional chemical and physical synthesis methods often generate toxic environmental impacts and limit clinical applications because of their low biocompatibility. Therefore, green synthesis has emerged as a safer and more sustainable alternative, utilizing biological resources such as plant extracts and microorganisms as natural reducing agents. This article systematically reviews recent advances in the eco-friendly synthesis of AgNPs, with particular emphasis on biosynthetic mechanisms and their biological effects against pathogenic bacteria and various cancer cell lines. Green-synthesized AgNPs have demonstrated significant effectiveness against multidrug-resistant bacteria through reactive oxygen species (ROS) induction and cell membrane disruption, while also exhibiting selective cytotoxic effects on cancer cells via apoptosis pathways. The novelty of this review lies in its comparative analysis of recent green synthesis approaches, including plant-mediated, microbial-mediated, and emerging green technologies, together with a comprehensive evaluation of their antibacterial and anticancer mechanisms and efficacy. In addition, this article discusses current challenges related to process standardization, biosafety, regulatory aspects, and future clinical prospects of green-synthesized AgNPs.
