Abstract

The primary component of aggregate demand, which represents both the stability of the local economy and the degree of community wellbeing, is household consumption. The purpose of this study is to examine how household spending in North Sumatra Province was affected by the Economic Growth Rate (LPE), inflation, and unemployment between 2001 and 2021. To assess both short-term and long-term correlations between variables, secondary data is analyzed using the Error Correction Model (ECM). According to the study's findings, long-term household consumption is positively and significantly impacted by LPE, indicating that economic expansion can raise people's purchasing power. In the meanwhile, both in the short and long term, unemployment and inflation have a detrimental but insignificant impact. A robust adjustment mechanism to the long-term balance is indicated by the significant correction coefficient of −0.969383. Therefore, it can be said that household spending in North Sumatra is mostly influenced by economic growth, with inflation and unemployment having comparatively little effect. The results of this research have implications for the importance of inclusive economic growth policies to strengthen household consumption, in line with achieving the Sustainable Development Goals (SDGs), especially Goal 1 (No Poverty) and Goal 8 (Decent Work and Economic Growth).

Abstract

The effect of Nb addition on the corrosion behavior of U–6Zr alloys within an aerated, demineralized water (DW) environment (pH 5.61) and its correlation of this addition with the mechanical and microstructural properties of the alloys were investigated. The U–6Zr–xNb alloys (x = 1, 4, and 7 wt.%) were synthesized by arc-melting U, Zr, and Nb. Additionally, the samples were mounted and polished, after which they were subjected to electrochemical corrosion analysis using a potentiostat. This evaluation was conducted in a DW medium (pH 5.6), representing an aerated atmosphere, at room temperature (27°C) and a potentiodynamic scan rate of 1 mV/cm2. The results demonstrate that Nb addition to the U–6Zr alloy, which yielded a U–6Zr–xNb (x = 1.4 and 7 wt.%) alloy, influenced the corrosion behavior in media, exhibiting a slightly acidic pH (5.61). Nb additions of up to 4 wt.% caused a continuous increase in the open-circuit potential, corrosion-current density, and corrosion rate (CR); however, these values decreased with the continuous increase in Nb concentrations to 7 wt.%. Furthermore, microstructural analysis via scanning electron microscopy and energy-dispersive X-ray spectroscopy revealed that the corrosion products across almost all U–6Zr–xNb test samples (x = 0, 1, 4, and 7 wt.%) were primarily stable uranium dioxide, which formed a protective layer, followed by oxynitride and zirconium(IV) oxide.Overall, the findings indicated that the varying Nb contents (1, 4, and 7 wt.%) dictated the CR, mechanical properties, and microstructure of the alloys. Ultimately, this study demonstrates the synthesis of U–6Zr–xNb alloys (x = 0, 1, 4, and 7 wt.%) with enhanced performance characteristics.

Abstract

Keterlibatan mahasiswa merupakan salah satu indikator penting dalam menentukan kualitas proses dan hasil pembelajaran di pendidikan tinggi. Namun, pembelajaran yang masih berpusat pada dosen sering kali membatasi partisipasi aktif mahasiswa, terutama pada materi yang menuntut kemampuan analitis dan pemecahan masalah. Penelitian ini bertujuan menganalisis pengaruh penerapan Problem Based Learning (PBL) berbantuan Google Sites dalam kerangka Outcome-Based Education (OBE) terhadap keterlibatan mahasiswa pada pembelajaran kinerja pembangunan daerah. Penelitian menggunakan pendekatan kuantitatif dengan desain survei eksplanatori. Sampel penelitian berjumlah 40 mahasiswa Program Studi Pendidikan Ekonomi yang dipilih melalui teknik purposive sampling. Data dikumpulkan menggunakan kuesioner yang telah melalui uji validitas dan reliabilitas, kemudian dianalisis menggunakan regresi linear sederhana dengan bantuan IBM SPSS Statistics 25. Hasil penelitian menunjukkan bahwa implementasi PBL berbantuan Google Sites dalam kerangka OBE berpengaruh positif dan signifikan terhadap keterlibatan mahasiswa dengan nilai signifikansi 0,002 (p < 0,05). Nilai koefisien determinasi sebesar 0,225 menunjukkan bahwa model pembelajaran yang diterapkan mampu menjelaskan 22,5% variasi keterlibatan mahasiswa. Temuan ini menunjukkan bahwa integrasi pembelajaran berbasis masalah, teknologi digital, dan pendekatan berbasis capaian dapat menciptakan pengalaman belajar yang lebih aktif, partisipatif, dan bermakna. Penelitian ini berkontribusi pada pengembangan strategi pembelajaran di perguruan tinggi melalui integrasi model pembelajaran, teknologi digital, dan orientasi capaian pembelajaran dalam meningkatkan keterlibatan mahasiswa.
