Abstract

Penambangan dapat dilakukan dengan tambang tertutup dan terbuka, sistem penambangan terbuka membutuhkan analisis lereng yang efektif untuk diterapkan. Metode yang dapat dipakai yaitu dengan metode geomekanika dan analisis tingkat kestabilan sebuah lereng. Metode geomekanika ini meliputi data Rock Mass Rating (RMR) dan Slope Mass Rating (SMR) yang bisa ditentukan dengan perhitungan data pemboran dan juga dari uji laboratorium. Penelitian ini berguna pada saat mendeskripsikan kondisi, klasifikasi dan kestabilan lereng. Berdasarkan hasil perhitungan RMR yang dilakukan yaitu lereng 1 dengan bobot RMR yaitu 62 poin kelas II. Pada lereng 2 dengan bobot RMR yaitu 72 poin, kelas II. Pada lereng 3 didapatkan nilai bobot total dari RMR yaitu 73 poin kelas II. Lereng 1, 2 dan 3 sama dengan deskripsi batuan baik, nilai kohesi dari kelas massa batuannya yaitu berada pada interval 300-400 kPa, dan sudut geser dalam interval 35⁰-45⁰. Berdasarkan hasil perhitungan SMR yang dilakukan yaitu pada lereng 1 nilai SMR yaitu 55,7 poin, kelas III dengan deskripsi normal, masih tergolong stabil sebagian, longsoran potensialnya baji dan kekar, kemudian stabilisasi secara sistematis. Pada lereng 2 nilai SMR yaitu 65,7 poin, kelas II dengan deskripsi baik, masih tergolong stabil, longsoran potensialnya blok batuan, dan stabilisasi secara okasional. Pada lereng 3 didapatkan nilai SMR yaitu 73,9 poin, kelas II deskripsi sama dengan lereng sebelumnya.

Abstract

Entrepreneurship education should be understood not only as a means of building a business, but also as a transformative educational process. Therefore, this systematic review aims to examine entrepreneurship education in Indonesia: What is currently known? A systematic literature review of trends, research focuses, and research agendas. This paper adopts a systematic literature review in the ScienceDirect and Semantic Scholar databases from 2021 to 2026, using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). Based on predetermined inclusion criteria, a total of 16 articles published between 2021 and 2026 were analyzed in-depth and systematically. This is because only 16 articles from that period aligned with the scope of this study on entrepreneurship education. The review’s findings indicate that entrepreneurship education plays a central role in shaping entrepreneurial competencies, intentions, and behaviors among students at various educational levels. The research findings confirm that experience-based pedagogical approaches, institutional support, and the integration of digital technology are key factors in enhancing the effectiveness of entrepreneurship education. This study is expected to contribute to fostering entrepreneurial intentions in developing competencies, innovative mindsets, and creating economic value in entrepreneurship education in Indonesia in the long term.

Abstract

Trust is a crucial factor in online business because it facilitates the transaction process by making buyers willing to accept and not doubt the actions of online sellers. Therefore, this systematic literature review aims to comprehensively examine how consumer trust influences purchasing behavior on marketplaces. A literature review from databases ScienceDirect, focusing on peer-reviewed articles and empirical studies from 2020 to 2026 was conducted from Q1 and Q2 indexed journals. The PRISMA flow diagram guided the process to ensure that the research process includes structured data, from identification to the presentation of results and supported bibliometric analysis using VOSviewer. A defined search criteria after thorough analysis, only 15 were suitable for synthesis and reporting. The Mendeley referencing tool and Microsoft Excel were instrumental in facilitating the analysis. The findings from the literature review indicate that customer trust is a multidimensional construct at the core of digital market sustainability, linking technological innovation, ethical considerations, regulatory frameworks, and business strategies. This literature review also indicates that trust has strong associations with blockchain, transparency, privacy, risk, and sustainability, reflecting its role as both a psychological and structural factor in legitimizing online transactions and fostering long-term relationships with consumers. Furthermore, this literature highlights trust as a mediator in repurchase intent and consumer engagement. This study affirms trust as a strategic foundation for the success of online markets and calls for interdisciplinary research to strengthen consumer trust in increasingly modern digital marketing.
