Abstract

Radiasi ultraviolet (UV) masih merupakan penyebab utama terjadinya kanker kulit, sehingga dipasaran banyak beredar sediaan krim atau gel yang berisi UV-filter. Oktil-metoksisinamat dan avobenzon adalah contoh zat aktif UV-filter. Berdasarkan Peraturan Kepala Badan Pengawasan Obat dan Kosmetik konsentrasi maksimum oktil metoksisinamat yang diizinkan sebagai sediaan kosmetik tabir surya adalah 10% dan untuk avobenzon sebesar 3%. Penelitian ini bertujuan untuk menetapkan kadar oktil metoksisinamat dan avobenzon dalam sedian gel tabir surya yang beredar di Kota Bandung dan menilai apakah sediaan tersebut memenuhi persyaratan tersebut diatas atau tidak. Penetapan kadar ini dilakukan dengan metode kromatografi cair kinerja tinggi (KCKT). Hasil penelitian menunjukan persamaan regresi linier oktil metoksisinamat y = 1634,7x + 8500,8 dengan R² = 0,9962; dengan nilai BD dan BK, 0,694 bpj dan 2,314 bpj. Persamaan linier untuk avobenzon yaitu y = 4329,9x +9268,5 dengan R2 = 0,9912, dengan nilai BD dan BK, 1,058 bpj dan 3,527 bpj. Validasi metode analisis dengan sampel simulasi meliputi akurasi menunjukkan persen perolehan kembali untuk konsentrasi sampel simulasi 80%; 100% dan 120% masing-masing adalah 102,011%; 112,368%; 108,490% untuk oktil metoksisinamat dan 81,722%; 98,01%; 117,8% untuk avobenzon. Presisi menunjukan keterulangan hasil pengukuran, untuk oktil metoksisinamat dan avobenson diperoleh nilai %RSD sebesar 1,641% dan 1,946%. Berdasarkan data penetapan kadar, maka ketiga sampel gel yang diteliti mengandung oktil metoksisinamat dan avobenzon dalam batas aman. Kata Kunci: Oktil metoksisinamat, avobenzon, tabir surya, UV-filter

Secondly, most students have a perception positive of YouTube Music, it can be seen that students stated that YouTube Music has many benefits as a learning media to improve listening. Thirdly, based on their perceptions, YouTube Music improves students' listening abilities by increasing students' vocabulary knowledge.

Abstract

This community service program aimed to improve the digital competence of elementary school teachers at SD Negeri Waru 01, Parung, Bogor Regency, through training on the utilization of Wordwall and Google Earth as interactive learning media. The background of this study is the gap between the demands of 21st century education and the reality of conventional learning practices still prevalent in elementary schools. The program was implemented over six months through workshops, direct practice (micro-teaching), and intensive mentoring. Results showed significant improvement in teachers' digital literacy, enabling them to independently design interactive learning activities using Wordwall (gamification quizzes, random wheels) and navigate Google Earth features for contextual IPAS learning. Students demonstrated increased motivation, active participation, and improved spatial-visual literacy. The integration of interactive digital media aligns with findings that game-based learning and socio-educational environments are key predictors of eco-digital literacy development. The program also produced a sustainable digital learning repository aligned with the school curriculum, supporting the implementation of the Merdeka Curriculum in elementary education.
