Abstract

The synthesis of acetins from glycerol is achieved through esterification assisted by a solid acid catalyst and microwave irradiation. Diacetin and triacetin, suitable as biofuel additives, are produced using biogenic silica from bamboo leaves, which is chemically activated with strong acid and calcined. No research has utilized silica catalysts derived from bamboo leaf ash to produce diacetin and triacetin. This study aims to employ bamboo leaf-based heterogeneous catalysts to enhance triacetin selectivity, simplify product purification and separation, and enable catalyst reuse. Furthermore, microwave application can accelerate the reaction time. The best total selectivity for diacetin and triacetin was obtained under operating conditions of 3% catalyst concentration, a 1:6 molar ratio, and 60 minutes of microwave irradiation. The yields of diacetin and triacetin under these conditions were 65.80% and 18.70%, respectively. GC-MS and FTIR analysis confirm the presence of monoacetin, diacetin, and triacetin, with a total selectivity for diacetin and triacetin of 84,50%.

Abstract

This study aims to determine the effect of interactive PowerPoint-based learning media on students’ learning interest in Pancasila education among fourth-grade students at SDN 125 Pekanbaru. The research employed a quantitative approach with a quasi-experimental design, specifically the Pretest–Posttest Control Group Design. The population consisted of all fourth-grade students of SDN 125 Pekanbaru, with a total sample of 42 students 23 students from class IV-A as the experimental group and 21 students from class IV-B as the control group. The data were collected using a learning interest questionnaire based on a Likert scale, which had been tested for validity and reliability. Data analysis included normality, homogeneity, and independent sample t-tests with a significance level of 0.05. The findings revealed that the average learning interest score of the experimental group increased from 67.30 to 86.52, while the control group’s score rose from 66.95 to 74.43. The calculated t-value of 4.827 with a Sig. (2-tailed) value of 0.000 < 0.05 indicates a significant difference between the two groups. The N-Gain score of 0.59 in the experimental class (moderate to high category) demonstrates a greater improvement in learning interest compared to the control class (N-Gain = 0.22). Based on these results, it can be concluded that the use of interactive PowerPoint-based learning media has a significant positive effect on enhancing students’ learning interest in Pancasila education.

Abstract

The utilization of Family Medicinal Plants (TOGA) is a strategic effort to enhance community health self-reliance, reduce dependence on synthetic drugs, and preserve local biodiversity. In Nagari Batu Tanjung, Talawi District, Sawahlunto City, the potential for TOGA is high due to favorable geography and extensive backyard land. However, its use remains limited because of low herbal literacy, minimal organic cultivation skills, and the absence of a properly managed communal garden. This community service program aimed to empower residents through education, direct practice, and guidance in cultivating and processing medicinal plants. Activities included awareness sessions on TOGA’s benefits, land preparation, planting of herbal seeds (ginger, turmeric, cardamom, sungkai, Java turmeric, aloe vera), and the establishment of a model TOGA garden. Based on pre- and post-test results from 40 participants, knowledge and cultivation skills improved significantly—from 40% to 95% of participants understanding proper TOGA cultivation. Active collaboration among residents, village officials, and students ensured the program’s success. Through Q&A sessions and hands-on practice, the community gained practical skills suited to local conditions. The established TOGA garden now serves as a learning medium, a health-supporting initiative, and a foundation for developing herbal products that promote sustainable economic empowerment.

Abstract

The development of science and technology in the era of globalization and the Industrial Revolution 4.0 demands that Islamic education undergo a paradigm shift without losing its Islamic identity. This study aims to analyze the relevance of contemporary Islamic philosophy in the development of Islamic Religious Education (PAI), particularly in responding to the challenges of modernity, globalization, and the digitalization of education. Contemporary Islamic philosophy is understood as a framework of thought that seeks to harmoniously integrate reason, revelation, spiritual values, and social reality. Through a literature review approach, this study examines the thoughts of classical and contemporary Islamic educational philosophy figures, such as Ibn Khaldun, Ibn Sina, and K.H. Ahmad Dahlan, and their implications for curriculum, learning methods, and student character development. The study's findings demonstrate that contemporary Islamic philosophy has significantly contributed to strengthening the holistic, integrative, and contextual orientation of Islamic education. The integration of the values ​​of monotheism, morality, and critical thinking serves as an essential foundation for developing a Muslim character that adapts to changing times without losing its Islamic identity. Therefore, contemporary Islamic philosophy is relevant as a conceptual foundation for the development of Islamic Religious Education in the modern era.

Abstract

Kepuasan pasien adalah hasil penilaian dalam bentuk respon perasaan senang dan puas pada pasien karena terpenuhinya harapan dan keinginannya dalam menggunakan dan mendapatkan pelayanan kesehatan. Berdasarkan hasil survei awal, pasien mengatakan kepuasan pasien masih belum tercapai sepenuhnya dikarenakan pelayanan yang diberikan belum maksimal. Tujuan penelitian ini adalah untuk melihat bagaimana evaluasi penerapan standar mutu pelayanan kesehatan terhadap kepuasan pasien di Puskesmas Babeko tahun 2025. Desain penelitian ini adalah menggunakan metode kualitatif. Informan penelitian ini adalah petugas puskesmas dan pasien yang berkunjung. Jenis data dalam penelitian ini adalah data primer dan data sekunder. Teknik analisis data kualitatif berupa reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa secara umum standar mutu telah diterapkan melalui kebijakan, sumber daya manusia, serta dimensi mutu pelayanan. Meskipun sebagian besar pasien menyatakan puas, ditemukan kekurangan pada aspek ketersediaan sarana prasarana dan keterbatasan tenaga asisten apoteker. Kesimpulan penelitian ini adalah kepuasan pasien di Puskesmas Babeko tergolong baik, namun masih perlu penguatan pada pemenuhan sarana prasarana dan pemerataan sumber daya manusia agar mutu pelayanan dapat lebih optimal.
