Abstract

Background: Karya ilmiah dan literasi remaja merupakan keterampilan yang penting untuk dimiliki oleh generasi abad 21. Metode: Mitra dalam kegiatan pengabdian ini adalah siswa dan pengasuh Panti Asuhan Putri ‘aisiah Riverside yang keseluruhan berjumlah 15 orang. Metode pengabdian yang dilakukan adalah dengan Focus Group Discussion (FGD), pembentukan kelompok KIR, serta pembuatan KIR. Pengumpulan data dilakukan dengan menggunakan instrumen pre-test serta rubrik penilaian artikel karya ilmiah remaja. Hasil: Hasil program pengabdian menunjukkan bahwa pemahaman awal siswa tentang KIR tergolong. Selanjutnya perolehan skor awal KIR yang dihasilkan oleh dua kelompok siswa yang terpilih untuk lomba karya tulis ilmiah (LKTI) remaja nasional hanya mencapai 36 dan 53. Namun, setelah pendampingan yang dilakukan oleh tim pengabdian masyarakat, skornya meningkat signifikan mencapai 70 dan 95 sehingga salah satu dari dua kelompok tersebut memenangkan LKTI nasional sebagai juara ketiga. Kesimpulan: Pendampingan untuk memperkuat keterampilan remaja dalam membuat karya ilmiah dan literasi sangat disarankan selama pandemi COVID-19.

Abstract

Koi fish coloration is genetically significant, but environmental factors and color quality can lead to degradation. Some individuals use synthetic dyes to enhance their appearance, which harms the environment. This study explored the effects of microencapsulated Rose sp. flower anthocyanin (MRFA) as a natural alternative dye to enhance the color of Sanke and Kohaku koi fish. Sanke exhibits orange-black hues, while Kohaku shows orange-white hues, allowing for comparative analysis. Before the experiment, MRFA was analyzed using FESEM and XRD to assess the particle size distribution and shape of the anthocyanin microcapsules. A Randomized Complete Design (CRD) with four treatments (T0, 150 mg (T1), 300 mg (T2), and 450 mg (T3)) and five replications were used. Data was analyzed with SPSS. Results showed that MRFA particles were distributed, though not entirely homogeneous (14 m to 170 m), with XRD spectra indicating interactions between maltodextrin and Rose sp. anthocyanin. Results showed that MRFA significantly improved certain color parameters in Sanke, particularly at moderate doses (T1 and T2), but the control group (T0) outperformed MRFA in some cases. In Kohaku, no significant improvement was observed compared to the control, suggesting that MRFA was less effective in enhancing whiteorange pigmentation. Overall, our findings indicate that MRFA supported koi growth but showed limited, strain-specific effects on coloration. Further studies with longer trials and larger populations are needed to confirm its potential as a natural feed additive.Keywords:Herbal extractCyprinus carpioKohakuPigmentSanke
