Abstract

Fly Ash dikategorikan sebagai limbah berbahaya dan beracun yang dapat membahayakan lingkungan hidup, kesehatan, dan kelangsungan hidup manusia dan makhluk lainnya. Fly Ash ini terdapat dalam jumlah yang cukup besar, sehingga memerlukan pengelolaan agar tidak menimbulkan masalah lingkungan seperti pencemaran udara, atau perairan dan penurunan kualitas ekosistem. Salah satu alternatif untuk mengurangi limbah tersebut yaitu digunakan sebagai campuran pada beton sebagaimana dilakukan pada penelitian ini. penelitian ini adalah untuk mengetahui bagaimana pengaruh fly ash (abu batubara) sebagai bahan reduksi semen pada campuran beton. Persentase Fly Ash yang digunakan pada penelitian ini adalah 5%, 15%, dan 25 % dari berat semen yang digunakan pada campuran beton. Penelitian ini dilakukan di laboratorium Balai Besar Pelaksanaan Jalan Nasional V Palembang, dengan menggunakan benda uji ukuran 15cm x 15cm x 60cm dengan kuat tekan beton rata-rata 25 MPa. Dari hasil uji kuat lentur pada umur 28 hari untuk beton tanpa fly ash, 5% fly ash, 15% fly ash, dan 25% fly ash didapatkan kuat lentur rata-ratanya secara berurutan sebesar 5,48MPa, 7,38MPa, 4,57MPa dan 4,93 MPa. Hasil uji kuat lentur tersebut didapatkan peningkatan koefisien konversi kuat tekan secara berurutan sebesar 0,63, 1,07, 0,42 dan 0,5 terhadap nilai koefisien konversi berdasarkan SNI 2847:2013 pers. 9-10 sebesar 0,62. Bila dilihat dari komposisi campuran dengan menggunakan fly ash didapatkan pengurangan pemakaian jumlah semen dalam campuran 1 m3 beton sebesar 22,55kg (5% fly ash), 67,65 kg (15% fly ash), dan 112,75 kg (25% fly ash). Kata Kunci: kuat lentur, reduksi semen, fly Ash

Abstract

This study examines the phenomenon of creator teachers on TikTok as a form of digital professionalism that represents the integration of ethical values, aesthetics, and educational philosophy. The focus of the research lies in how teachers negotiate moral responsibility and creative expression in the algorithmic culture of social media. The aim of this research is to analyze the philosophical meaning behind teachers' digital representations as well as interpret how moral and aesthetic values are reflected in their pedagogical practices. The method used is digital netnography with four stages: online observation, digital documentation, audience interaction analysis, and researcher reflection. A total of eight teacher accounts were analyzed with a total of 80 videos using a categorization of themes that focused on ethics, aesthetics, and professionalism. The results showed that 62.5% of the content was educational and featured learning innovations, while the other 37.5% contained elements of entertainment and social interaction. High audience interaction shows public appreciation for the creativity and integrity of teachers. Popularity is not solely generated by algorithms, but by the appreciation of moral values and pedagogical beauty in the actions of teachers. Based on the framework of arete and phronesis from Aristotle and the concept of aesthetic experience from Dewey (1934), this study concludes that the digital professionalism of teachers is a form of reflective praxis that combines ethical responsibility and creative expression. This research makes a theoretical contribution by integrating digital netnography and educational philosophy, and shows that teachers in the digital era play the role of moral and creative agents who maintain the dignity of their profession in the algorithmic space.
