C-Reactive Protein (CRP) adalah protein fase akut yang meningkat saat terjadi peradangan dan dapat menjadi indikator inflamasi pada penderita asam urat. Pemeriksaan CRP dapat memberikan gambaran adanya inflamasi, terutama pada pasien dengan komorbiditas seperti hipertensi dan diabetes mellitus (DM). Tujuan: Mengetahui gambaran kadar CRP pada penderita asam urat di RSUD Siti Fatimah Az-Zahra Provinsi Sumatera Selatan. Metode: Penelitian ini menggunakan pendekatan deskriptif observasional dengan pendekatan cross sectional. Sampel sebanyak 30 penderita asam urat dipilih menggunakan teknik accidental sampling. Pemeriksaan laboratorium CRP dengan metode aglutinasi. Hasil: Sebanyak 30% responden memiliki kadar CRP tidak normal, sementara 70% normal. Pada responden dengan riwayat penyakit, kadar CRP tinggi ditemukan pada 36,4% kasus. Sementara pada responden tanpa riwayat penyakit tersebut, kadar CRP tinggi hanya sebesar 10,5%. Kesimpulan: Mayoritas penderita asam urat memiliki kadar CRP normal. Namun, kadar CRP lebih tinggi pada pasien dengan riwayat penyakit DM, yang menunjukkan peran komorbiditas dalam meningkatkan risiko inflamasi. Saran: Kepada para klinisi seyogyanya melakukan pemeriksaan asam urat untuk melihat tingkat inflamasi pada penderita asam urat, terutama bagi yang memiliki riwayat penyakit hipertensi atau diabetes melitus. Kata Kunci: Hiperurisemia, CRP, hipertensi, DM, inflamasi

Abstract

Ribonucleic acid (RNA) is a crucial molecule in gene expression analysis, yet its isolation from solid tissues, such as endometriotic lesions, poses significant challenges due to complex tissue structure and high RNase activity. TRIzol is a widely utilized reagent for RNA extraction, known for its efficacy in lysing cells and stabilizing RNA. This study aimed to compare the quality of RNA extracts from endometriotic lesion tissue samples using TRIzol-based and non-TRIzol-based methods. A quasi-experimental design was employed, involving a control group and an experimental group, with non-randomized sample allocation. A total of 28 samples were analyzed in both the control and treatment groups. The results demonstrated that TRIzol treatment significantly increased the median RNA concentration from endometriotic lesion tissues, yielding 288.6 ng/μL compared to 118.2 ng/μL in the non-TRIzol group (p=0.001). Furthermore, there was a significant difference between TRIzol and non-TRIzol groups in RNA purity based on the Å260/280 ratio (median: 2.00; p-value:0.024). However, there wasn’t a significant difference in the Å260/230 ratio (median: 2.11; p-value: 0.247). In conclusion, these findings indicate that while TRIzol extraction provides higher RNA yield, the non‑TRIzol method ensures slightly superior sample purity, supporting its reliability for downstream transcriptomic analyses.

Abstract

This study investigates the implementation of Digital Game-Based Learning (DGBL) as a creative solution to reduce learning boredom at Yos Sudarso Metro High School. It explored the impact of game-based tools on student engagement, motivation, and understanding during the learning process. This research employed a qualitative method, with data collected through classroom observations and Google Forms questionnaires. The data were analyzed using Qualitative Thematic Analysis to identify recurring patterns in students’ experiences. The findings indicated three main themes, namely increased student engagement, perceived effectiveness of digital game platforms, and challenges in implementation. Platforms such as Quizizz and Wordwall encourage interactive and enjoyable learning, leading to improved comprehension, particularly in English subjects. This qualitative study involved 32 eleventh-grade students selected through purposive sampling, with data collected through classroom observations and a structured questionnaire.  However, limitations such as unequal access to technology and inconsistency in tool effectiveness remain obstacles. The study concludes that DGBL is a promising approach to minimize learning boredom and fostering a more dynamic, student-centered learning environment. These results suggest that integrating game-based tools into classroom instruction can enhance participation and learning outcomes, provided that implementation challenges are addressed with proper planning and resources

Abstract

Religious commitment, particularly within Islamic contexts, is often viewed as a guiding framework for promoting values such as tolerance, respect, and social harmony; however, differing interpretations and personal expressions of religiosity can sometimes challenge these ideals, necessitating deeper exploration of how religiosity influences social interactions. The study investigates the relationship between religious commitment and respect for others regarding the levels of tolerance behavior among university students. The study employed a descriptive quantitative cross-sectional survey from June 16 to August 16, 2023, with a sample of 334 enrolled in the College of Sharia at Yarmouk University in Jordan. The survey consists of three main scales: religious commitment, respect for others, and tolerance. Students’ demographic data, including gender, nationality, age group, academic department, and the year of study, were also collected via the questionnaire. The findings highlight significant gender differences in religious commitment, with males demonstrating higher levels than females. While no significant age differences were observed in religious commitment, tolerance varied notably, particularly among the 24-26 age group. The study participants represented a diverse range of countries of origin. A country-wise analysis revealed that students from Thailand have the highest religious commitment, underscoring the influence of cultural contexts. Departmental comparisons showed no significant differences, although the findings highlight that respect for others impacts tolerance, religious commitment and demography have almost no effect as predicted. The findings emphasize the primary role of respect in fostering social harmony, suggesting that future interventions should focus on promoting respect as a fundamental value in Islamic culture to enhance tolerance.

Abstract

The mechanical behavior of materials at the nanoscale level has attracted significant attention in materials science research. This study investigated the impact of deformation on the strain energy of ultrafine-grained (UFG) copper produced by equal channel angular pressing (ECAP). X-ray and neutron diffraction techniques were employed to analyze the changes in strain energy of the copper samples subjected to varying levels of deformation. The results of the study indicate that the strain energy of the UFG copper increased with increasing levels of deformation due to the formation of dislocations with high density in the copper crystal structure. The study also found that the increase in strain energy was more significant in the initial stages of deformation and then reached a plateau as deformation progressed. This study provides valuable insight into the mechanical behavior of UFG copper and the role of deformation in altering its strain energy. The results can contribute to developing new materials with improved mechanical properties for various aerospace, automotive, and biomedical applications. The study highlights the importance of using advanced techniques such as X-ray and neutron diffraction to accurately investigate the nanoscale mechanical behavior of materials.

Abstract

Background: Indonesia’s expanding digital legal-service ecosystem has brought generative AI into public-facing legal assistance, yet its authority is increasingly produced through platform discourse before its professional, ethical, and regulatory boundaries are fully settled. Objective: This study aims to examine how generative AI is represented in Indonesian digital legal services and how such representation shifts AI from a tool of legal assistance toward a form of automated authority. Method: Using critical discourse analysis, this study analyses 27 publicly accessible documents consisting of platform pages, app descriptions, professional media articles, legal-policy documents, and regulatory-context materials. Results: Findings show that AI authority is constructed through professional research vocabulary, efficiency claims, innovation narratives, access-to-justice language, and references to regulatory accountability. Findings also indicate that users are positioned as self-service legal actors whose access to law is mediated by platform interfaces, automated summaries, guided consultation, and document-generation tools. Implication: Findings further reveal that accountability is unevenly articulated, with legal responsibility often dispersed across professionals, users, ethical soft regulation, data-protection discourse, and platform claims. Novelty: The novelty of this study lies in shifting Indonesian AI-law scholarship from adoption and regulation debates toward the discursive production of automated legal authority.
