Abstract

To improve the quality of learning, learning evaluation has an important role. One of the learning evaluations that is often carried out is daily assessments to see the achievement of particular material. The aim of this research is to describe the quality of mathematics questions in statistics material for junior high school students. The method used in this research is quantitative descriptive research assisted by the AnBuSo program and R studio software. The data collection technique used documentation techniques, with data sources in the form of mathematics questions on statistics material. Question items analysis is applied to prove validity, estimate reliability, level of difficulty, discrimination, as well as analyzing the factors that cause the question items to be difficult and have poor discrimination. The respondents in this research were 200 students taken from three junior high schools in DIY. Meanwhile, qualitative data analysis is used to explain the difficulty index and discrimination of the test items. The results of this research show that the Aiken value is valid, and the reliability estimates are quite good. The results of analysis based on the CTT and IRT approaches obtained a good mean index of difficulty and discrimination. These findings imply that the validated and reliable question items can be used as a reference for developing higher-quality assessments to improve student learning outcomes.

Abstract

Wood submerged in brackish and marine environments is highly susceptible to degradation by marine borers, which can compromise its structural integrity over time. Resak wood (Vatica sp.), widely used in boat construction, is frequently exposed to seawater, making it vulnerable to such bio-deterioration. This study aimed to assess the intensity of marine borer attacks on resak wood at different immersion depths (5 cm, 25 cm, and 50 cm) over three months in the estuary of Mempawah River, Mempawah Regency. Test samples (2 cm × 5 cm × 30 cm) were deployed, and data were analyzed using a Completely Randomized Design (CRD) with five replications, totaling 15 samples. The results revealed that resak wood exhibits high natural durability and is classified as durability class I, indicating strong resistance to marine borer infestations. The recorded weight loss percentages were 1.48% at 5 cm depth, 1.81% at 25 cm depth, and 2.69% at 50 cm depth, with statistical analysis confirming a significant effect of immersion depth on weight loss. This suggests that while resak wood is highly resistant, degradation intensifies with increasing submersion depth. Four marine borer species were identified in the estuarine waters of the Mempawah River: Limnoria sp., Balanus sp., Nereis sp., and Teredo sp. Their presence highlights the potential threat to submerged wooden structures in the region. Despite its durability, prolonged exposure and greater immersion depth may gradually reduce the structural performance of resak wood. Further long-term studies are recommended to evaluate its resistance under diverse environmental conditions and to explore protective treatments that could enhance its durability in marine applications.

Abstract

Penelitian ini dilatarbelakangi oleh pesatnya transformasi digital yang mendorong perubahan perilaku ekonomi masyarakat, khususnya di kalangan anak muda Indonesia yang menjadi pengguna utama sistem pembayaran digital berbasis QRIS. Fenomena ini menimbulkan kebutuhan mendesak akan peningkatan literasi keuangan agar penggunaan teknologi finansial berlangsung secara bijak dan berkelanjutan. Tujuan penelitian ini adalah untuk menganalisis pengaruh literasi keuangan dan gaya hidup digital terhadap penggunaan QRIS di kalangan anak muda Indonesia pada periode 2024–2025. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei daring melalui kuesioner yang disebarkan kepada 72 responden berusia 18–30 tahun yang aktif menggunakan media sosial dan transaksi digital. Data dianalisis menggunakan regresi linier berganda dengan uji validitas, reliabilitas, serta asumsi klasik untuk memastikan kelayakan model. Hasil penelitian menunjukkan bahwa literasi keuangan dan gaya hidup digital berpengaruh positif dan signifikan terhadap penggunaan QRIS, dengan nilai koefisien determinasi sebesar 63,7%, yang berarti kedua variabel mampu menjelaskan sebagian besar variasi perilaku penggunaan QRIS. Temuan ini menegaskan bahwa tingkat pemahaman keuangan yang baik serta gaya hidup digital yang kuat mendorong individu untuk lebih aktif, efisien, dan aman dalam menggunakan pembayaran non-tunai. Penelitian ini berkontribusi pada pengembangan literatur fintech dan perilaku keuangan generasi muda, serta memberikan implikasi praktis bagi lembaga keuangan dan regulator dalam merancang strategi edukasi literasi keuangan digital menuju masyarakat tanpa uang tunai yang inklusif dan berkelanjutan.
