Abstract

The use of non-food dyes is a problem in food safety. One of the efforts to solve this problem is the making of natural coloring products from purple sweet potato anthocyanin pigments. Anthocyanins are sensitive to oxidative damage, so encapsulation techniques need to be used to preserve bioactive compounds. Encapsulation with the coacervation method involves coating anthocyanins as the active ingredient with pectin and alginate as gel matrices, based on the principle of ionic gel formation. This study aimed to determine the optimal alginate concentration for the formation of anthocyanin encapsulates and to identify the color characteristics and interactions of the encapsulated anthocyanins from purple sweet potato. This study used various concentrations of alginate (0%, 0.5%, 1%, and 1.5%). The research parameters used were total anthocyanin and antioxidant activity (IC50). The findings indicated that the optimal concentration of alginate for preserving the solubility and stability of anthocyanin, derived from the bioactive compounds in purple sweet potatoes, was 1% alginate. This concentration resulted in a total anthocyanin content of 20.77 mg/L and an antioxidant activity (IC50) of 4049.73 ppm. A higher alginate concentration results in stronger gel formation; however, it simultaneously weakens the ability of alginate to bind anthocyanin as an active ingredient. This is attributed to the increase in viscosity, making the incorporation of the anthocyanin matrix into the encapsulates more difficult. Despite the very weak antioxidant activity, these anthocyanin encapsulates hold potential as natural food colorants for safe applications in acidic food products like beverages.

Abstract

The purpose of this study is to ascertain how the Discovery Learning learning paradigm, with Kahoot's assistance, affects the mathematical critical thinking abilities of SMAN 1 Utan class X pupils throughout the 2024/2025 academic year. This type of research is a quasi-experimental with a Post-test Only Control Group Design, involving two classes, namely the experimental class (X-6) and the control class (X-5). While the control class employs a traditional learning model, the experimental class uses the Discovery Learning learning paradigm with Kahoot's help. Post-test questions on critical thinking abilities and observation sheets for learning implementation serve as the research tools. According to the findings, the experimental class's average post-test score was 78.27, which was higher than the control class's average score of 64.89. A statistically significant difference between the two classes was revealed by the Mann-Whitney U test. With an effectiveness of 78.93%, the effect size (Cohen's d) of 0.80407 suggests a moderate effect. The experimental class is primarily in the very high category on the interpretation and evaluation indicators, while the control class is primarily in the high category on the analysis indicator and low on the inference indicator, according to the distribution of critical thinking ability categories by indicator. These results indicate that the use of Kahoot-assisted Discovery Learning can influence students' critical thinking abilities overall.

Abstract

Penelitian ini mengkaji dan menganalisis pengaruh Sistem Informasi Pemerintah Daerah (SIPD) terhadap kepuasan pengguna. Penelitian ini dilatarbelakangi oleh masih rendahnya kualitas implementasi SIPD pada berbagai pemerintah daerah, seperti keterbatasan sinkronisasi data, kendala stabilitas sistem, dan perbedaan kompetensi pengguna. Kondisi tersebut menuntut evaluasi berbasis persepsi pengguna dengan pendekatan End User Computing Satisfaction (EUCS). Penelitian ini menggunakan metode kualitatif deskriptif dengan pengumpulan data melalui kuesioner terstruktur yang dirancang untuk menggali persepsi, pengalaman, serta tingkat kepuasan pengguna SIPD. Data diperoleh dari 80 pejabat penatausahaan keuangan dan selanjutnya dianalisis menggunakan pendekatan Partial Least Squares (PLS) melalui aplikasi SmartPLS versi 0.4. Penelitian ini juga menguji peran infrastruktur teknologi informasi sebagai variabel moderasi dalam hubungan antara SIPD dan kepuasan pengguna. Hasil penelitian menunjukkan bahwa infrastruktur TI tidak berpengaruh signifikan dalam memoderasi hubungan antara SIPD dan kepuasan pengguna. Dengan kata lain, kesiapan atau ketersediaan infrastruktur TI tidak memperkuat maupun memperlemah pengaruh SIPD terhadap kepuasan pengguna. Temuan ini dapat dijelaskan oleh karakteristik SIPD yang bersifat terpusat (cloud-based), sehingga kinerja sistem lebih bergantung pada server pusat dibandingkan dengan infrastruktur teknologi di masing-masing pemerintah daerah.
