Abstract

Abstract: Higher education institutions face increasing demands to enhance educational quality, accountability, and global competitiveness. However, quality assurance initiatives often fail to foster a strong quality culture and are therefore frequently perceived as merely administrative procedures. This study aims to identify strategies recommended in the literature to strengthen quality culture through internal quality assurance (IQA) systems in higher education institutions. The method employed is a Systematic Literature Review (SLR), involving a comprehensive search of articles across reputable databases using Boolean strings related to quality culture, higher education, and internal quality assurance. This process is followed by screening based on inclusion–exclusion criteria and thematic analysis of the selected studies. Out of an initial 149 articles, only 5 met the eligibility criteria and were included in the final analysis to synthesize the findings. The results reveal four key strategies for strengthening quality culture: (1) reinforcing quality-oriented leadership, (2) establishing systematic governance of IQA, (3) fostering stakeholder engagement, and (4) developing human resource competencies through innovation and continuous improvement. Therefore, a sustainable quality culture can be established when IQA is not merely positioned as a compliance mechanism, but rather as a framework for organizational transformation that is implemented collaboratively and consistently across all levels of higher education institutions. Keywords: Internal Quality Assurance; Higher Education; Quality System; Continuous Improvement; Stakeholder Engagement   Abstrak: Perguruan tinggi menghadapi tuntutan peningkatan mutu pendidikan, akuntabilitas, dan daya saing global, namun upaya penjaminan mutu sering kali belum berhasil menumbuhkan budaya mutu yang kuat sehingga hanya dipandang sebagai prosedur administratif semata. Penelitian ini bertujuan mengidentifikasi strategi yang direkomendasikan dalam literatur untuk memperkuat budaya mutu melalui sistem penjaminan mutu internal di perguruan tinggi. Metode yang digunakan adalah Systematic Literature Review (SLR) dengan pencarian artikel pada berbagai database bereputasi menggunakan Boolean string terkait quality culture, higher education, dan internal quality assurance, dilanjutkan dengan proses screening berbasis kriteria inklusi–eksklusi, serta analisis tematik terhadap artikel yang lolos seleksi . Dari 149 artikel awal, hanya 5 artikel yang memenuhi kriteria dan dianalisis sebagai dasar penyusunan sintesis temuan. Hasil menunjukkan empat strategi utama dalam penguatan budaya mutu, yaitu penguatan kepemimpinan mutu, tata kelola SPMI yang sistematis, keterlibatan pemangku kepentingan, dan pengembangan kompetensi SDM melalui inovasi serta continuous improvement. Dengan demikian, budaya mutu akan terbangun ketika IQA tidak hanya menjadi alat kepatuhan, tetapi menjadi kerangka transformasi organisasi yang dijalankan secara kolaboratif dan konsisten di seluruh level perguruan tinggi.

Abstract: The transformation toward a sustainable economy has become a strategic necessity amid the growing pressures of climate crisis, environmental degradation, and social inequality. Technological innovation is widely regarded as a key driver in balancing economic growth with environmental preservation and social inclusivity. This study aims to identify key technologies that support the sustainable economy, analyze their implementation strategies across major sectors in Indonesia, and evaluate their impact on the economic, environmental, and social dimensions (triple bottom line). This research employs a qualitative-descriptive approach through literature review and case analysis in the energy, agriculture, manufacturing, and MSME sectors. The findings indicate that artificial intelligence (AI), Internet of Things (IoT), big data, blockchain, renewable energy, and green fintech significantly contribute to improving resource efficiency, reducing emissions, enhancing supply chain transparency, and expanding access to green financing. However, several challenges remain, including infrastructure readiness, high initial investment costs, limited digital literacy, non-adaptive regulatory frameworks, and unequal access to technology. This study recommends strengthening incentive-based policies, developing cross-sector innovation ecosystems, and enhancing green-digital human resource capacities to accelerate the growth of a sustainable economy in Indonesia.

Metode analisis yang digunakan adalah regresi linear berganda dengan uji t secara parsial, uji F secara simultan, dan koefisien determinasi (R²) dengan tingkat signifikansi 5%. Hasil penelitian menunjukkan bahwa secara simultan ROA, CR, dan DER berpengaruh signifikan terhadap pertumbuhan laba, dibuktikan dengan nilai Fhitung sebesar 3,705 > Ftabel 2,833 dengan signifikansi 0,019 < 0,05. Secara parsial, ROA tidak berpengaruh terhadap pertumbuhan laba dengan nilai thitung 0,928 < ttabel 2,01808 dan signifikansi 0,359 > 0,05. Variabel CR juga tidak berpengaruh terhadap pertumbuhan laba dengan nilai thitung 0,317 < ttabel 2,01808  dan signifikansi 0,753 > 0,05. Sedangkan variabel DER berpengaruh signifikan negatif terhadap pertumbuhan laba dengan nilai thitung -2,893 < -ttabel 2,01808 dan signifikansi 0,006 < 0,05. Koefisien determinasi (R²) sebesar 0,156 yang menunjukkan bahwa variabel ROA, CR, dan DER mampu menjelaskan pertumbuhan laba sebesar 15,6%, sedangkan sisanya 84,4% dipengaruhi oleh variabel lain di luar penelitian ini. Kata Kunci: Profitabilitas (ROA), Likuiditas (CR), Solvabilitas (DER), dan Pertumbuhan Laba
