Abstract

This study aims to evaluate the validity and reliability of a science literacy instrument based on the Rasch Model in measuring students' abilities on socio-scientific issues. The analysis was conducted on 20 items using the Winsteps software. The results indicate that the instrument demonstrated good reliability, with an item reliability value of 0.96 and a person reliability value of 0.65. The Wright Map revealed that most items were well-aligned with the respondents’ abilities, although some items fell outside the majority's ability range. The analysis of item difficulty showed adequate variation, with the most difficult item at logit 2.09 and the easiest at logit -2.49. However, the DIF analysis identified bias in item 20M, which exhibited significant differences between male and female groups. These findings highlight the importance of revising specific items to enhance fairness in measurement. This study provides significant contributions to the development of educational assessment instruments based on the Rasch Model, ensuring validity, reliability, and fairness in evaluation. The instrument is expected to serve as an effective tool to support science literacy-based learning across various educational levels.

Abstract

The rapid expansion of decentralized exchanges (DEXs) has reshaped cryptocurrency trading, yet comparative cross-chain evaluations remain scarce, particularly in transaction efficiency, liquidity sustainability, and economic viability. This study conducts an on-chain comparative analysis of Uniswap (Ethereum), Raydium (Solana), and PancakeSwap (BSC) by examining transaction count, trade volume, protocol revenue, and total value locked (TVL). Using real-time blockchain data from DefiLlama, Dune Analytics, Artemis, Token Terminal, and Arkham, this research applies quantitative cross-chain modeling to assess the performance of each ecosystem. Findings reveal that Ethereum leads in trade volume and liquidity depth, driven by institutional adoption despite high transaction costs. Solana exhibits superior transaction efficiency, attracting high-frequency traders, though its lower TVL suggests liquidity retention challenges. BSC, once a major DeFi player, now faces stagnation, with declining trade volume and fragmented liquidity. Unlike prior studies focusing solely on transaction metrics, this research integrates protocol revenue as a sustainability indicator, offering a broader understanding of DEX viability. The results underscore the need for cross-chain liquidity bridges and Layer-2 scaling solutions to mitigate liquidity fragmentation and enhance DeFi efficiency. This study contributes to both academia and industry by providing empirical insights for blockchain developers, investors, and policymakers, emphasizing the importance of scalability, liquidity incentives, and revenue optimization. The findings support future research on multi-chain liquidity integration, AI-driven market-making, and governance frameworks, guiding the next evolution of decentralized financial ecosystems.

Abstract

Penelitian ini bertujuan untuk mengkaji efektivitas penerapan model Brain Based Learning yang dipadukan dengan laboratorium virtual (Olabs) terhadap kemampuan creative problem solving siswa. Jenis penelitian adalah Quasi-Eksperimen dengan desain non-equivalen control group design. Populasi penelitian meliputi seluruh siswa kelas X SMA Gajah Mada Bandar Lampung yang berjumlah 196 siswa, penentuan sample menggunakan teknik purposive sampling, dengan kelas X4 sebagai kelompok eksperimen dan kelas X6 sebagai kelompok kontrol, dengan masing-masing berjumlah 34 siswa dan 33 siswa. Instrumen penelitian terdiri dari tes berbentuk esai untuk mengukur kemampuan creative problem solving serta lembar observasi keterlaksanaan model pembelajaran. Analisis data dilakukan menggunakan uji independent sample t-test guna mengetahui peningkatan kemampuan setelah diberikan perlakuan. Hasil uji hipotesis menunjukkan nilai signifikansi sebesar 0.008 (p-value < 0.05), sehigga H0 ditolak dan Ha diterima. Berdasarkan hasil uji N-Gain nilai rata-rata kemampuan creative problem solving siswa pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Dengan demikian, model Brain Based Learning berbantuan laboratorium virtual (OLabs) berpengaruh signifikan terhadap kemampuan creative problem solving siswa.
