Abstract

Penggunaan teknologi semakin maju sehingga dunia pendidikan harus mengikuti adanya perkembangan tersebut, terutama dalam menunjang keterampilan abad-21 siswa salah satunya keterampilan problem-solving. Penelitian ini bertujuan untuk mendeskripsikan pengaruh WEBIMLAT terhadap keahlian guru fisika membuat media pembelajaran interaktif berorientasi keterampilan problem solving melalui Quizizz-web. Penelitian ini melibatkan total 27 guru fisika dari berbagai provinsi di Indonesia. Kegiatan WEBIMLAT ini terdiri dari beberapa tahap, yaitu Webinar, Pelatihan, Pendampingan dan Bimbingan. Guru-guru fisika sebagai peserta pelatihan menunjukkan bebapa capaian, yaitu: a) peserta mampu merancang media pembelajaran interaktif dengan memanfaatkan platform Quizizz-web untuk melatihkan keterampilan problem-solving siswa, b) peserta mampu membuat media presentasi berorientasi keterampilan problem-solving, dan c) peserta merasa memiliki pengetahuan terkait cara menyusun soal evaluasi yang memuat indikator physics problem-solving. Melalui kegiatan WEBIMLAT ini keahlian guru dalam membuat pembelajaran interaktif untuk melatih keterampilan problem-solving siswa mengalami peningkatan dan sangat berkembang.

Abstract

Excess free radicals trigger oxidative stress that accelerates skin aging and increases the risk of degenerative diseases. Efforts to counter it require safe and effective antioxidants based on natural ingredients. Telang flowers (Clitoria ternatea L.) and asoka leaves (Ixora coccinea L.) are known to be rich in flavonoids and phenolates, but data on the effectiveness of the combination of the two are limited. This study aims to assess the antioxidant activity of the mixture of the extracts of the two plants. Ethanol extracts of telang flowers and asoka leaves are prepared, the yield is determined, then phytochemical screening confirms the presence of alkaloids, flavonoids, saponins, and tannins. Anti-radical activity was tested by the DPPH method at three ratios (25 %:75 %, 50 %:50 %, 75 %:25 %) and compared with quercetin (2–10 ppm) as a positive control. The value of IC₅₀ is calculated through linear regression. The 50%:50% mixture showed the highest potency (IC₅₀ = 2.3237 ppm) and was classified as "very strong", close to quercetin (0.7631 ppm) and much better than each of the single extracts reported in the previous study (IC₅₀ telang flower 32.23 ppm; asoka leaf 150.12 ppm). These results indicate a synergy between the two bioactive compounds in simplicia in neutralizing free radicals. Conclusion: the combination of telogen flower–asoka leaf extract has the potential to be developed as a superior natural antioxidant for pharmaceutical or cosmetic products. Further research is recommended to focus on the fractionation of dominant compounds, formulation stability tests, and pre-clinical safety evaluation to in vivo applications.

Abstract

Technology at this time is something that is really needed to help make it easier to access everything efficiently, so an information system design has been developed which aims to make it easier for the public, especially in ordering travel tickets. So a design was built with the name GOTralis (GO Travel Bengkalis) as a means to help the public in ordering travel tickets. In this research, the author used the SDLC method, namely conducting a literature review regarding information systems, the web, SDLC, and application development tools. So this research can create a design that can make it easier for travel passengers to order travel tickets easily.
