Microalgae are photoautotrophic microorganisms that synthesize bioactive compounds, including antioxidant compounds. Exploratory research on microalgae with strong antioxidant capacity as free radical scavengers is interesting and important to do. This study aims to identify and evaluate the antioxidant capacity of microalgae. Water samples were diluted with multilevel dilution. Microalgae were isolated using the streak plate method, and four microalgae isolates were successfully cultivated in vitro. Identification was carried out by phylogenetic analysis based on 18S rRNA marker gene sequences, namely Chlorella vulgaris, Desmodesmus armatus, Dictyosphaerium ehrenbergianum, and Vitreochlamys incisa. Antioxidant capacity was evaluated using three methods, namely DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonate)), and FRAP (Ferric Reducing Antioxidant Power). IC50 as the concentration required to inhibit 50% of free radicals showed that methanol extract of C. vulgaris had a strong antioxidant capacity in the ABTS test with IC50 of 81.693 ppm and the highest in the DPPH test with IC50 of 297.451 ppm. In the FRAP test, the highest antioxidant capacity was in ethanol extract of D. ehrenbergianum isolate of 74.45 mg AAE/g. The D. armatus isolate had the lowest antioxidant capacity in the ABTS, DPPH, and FRAP tests.

This research was conducted to look at team components starting from the strengths and weaknesses of the team so that it can be used as evaluation material to make better improvements to the team to face the next match. This research also aims to confirm the findings of video analysis in the final match of the East Java Floorball men's team at the 2024 Aceh-Sumut PON XXI exhibition. This research methodology uses quantitative descriptive, which uses match video analysis data to paint a picture or reveal information about the facts. facts about the final field for the men's floorball team in East Java. The sample from this research was the East Java Floorball men's team who were the core players or who only played in the final round. The researcher's data sheet on video match analysis served as a tool. The quantitative descriptive data analysis method was applied using figures obtained from video study findings and evaluation results. From the results of video analysis of the final match of the East Java Floorball men's team, when compared with other strategies, it was found that the tactics of passing and controlling the ball gave the best results. Players gain an advantage when the opposing team has the ball as a result of frequently using this method and developing their game. The East Java Floorball men's team has better ball control than its opponents because their passing technique and ball control are superior.

Penelitian ini bertujuan untuk mengevaluasi efektivitas metode Talqin dan Tasmi' dalam meningkatkan keterampilan menghafal Al-Qur'an dan Hadits. Al-Qur'an sebagai petunjuk utama dalam Islam, serta Hadits sebagai sumber hukum kedua, memerlukan pendekatan pembelajaran yang efektif untuk mencapai pemahaman dan penghafalan yang baik. Metode penelitian yang digunakan adalah kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Data dianalisis secara deskriptif kualitatif untuk menginterpretasikan hasil wawancara dan observasi terkait penerapan metode Talqin dan Tasmi'. Hasil penelitian menunjukkan bahwa penerapan metode Talqin dan Tasmi' dilakukan dalam tiga tahapan: perencanaan dengan penyusunan RPP, pelaksanaan yang melibatkan pembagian kelompok dan pengoreksian bacaan, serta evaluasi melalui tes lisan individu dan observasi. Temuan menunjukkan peningkatan signifikan dalam keterampilan menghafal, yang tercermin dari peningkatan rata-rata nilai kelas dari 70 menjadi 85. Selain itu, metode ini juga memperbaiki kualitas pembelajaran dengan mendorong pemahaman materi, menciptakan suasana belajar interaktif, serta memperkuat hafalan dan kualitas bacaan Al-Qur'an. Faktor pendukung penerapan metode ini meliputi komitmen sekolah, kualifikasi guru, lingkungan belajar, dukungan orang tua, kedisiplinan guru, dan adanya budaya kompetisi. Sebaliknya, faktor penghambat termasuk perbedaan kemampuan siswa, keterbatasan waktu, kelelahan, gangguan eksternal, keterbatasan sumber daya, dan penggunaan gadget. Penelitian ini menyimpulkan bahwa metode Talqin dan Tasmi' efektif dalam meningkatkan keterampilan menghafal Al-Qur'an dan Hadits, dengan implikasi penting untuk pembelajaran yang lebih baik dan peningkatan kualitas pendidikan agama Islam.
