EFEK DIGITALISASI TERHADAP PERTUMBUHAN EKONOMI DI INDONESIA
No full textThis study examines the impact of digitalization on Indonesia\u27s economic growth from 2000 to 2022 using the Ordinary Least Squares (OLS) method. The research includes variables such as the digitalization index, labor force participation, foreign direct investment (FDI), domestic investment (DI), and education (mean years of schooling). The findings reveal that digitalization and FDI significantly and positively affect Indonesia\u27s GDP, indicating the pivotal role of technology adoption and international capital flows in economic expansion. Conversely, education exhibits a significant negative effect, suggesting possibly indicating a mismatch between educational output and labor market needs. Meanwhile, labor force participation and domestic investment show no significant effect on growth. These results highlight the need for strategic improvements in digital infrastructure, educational quality, and investment policy to enhance the inclusiveness and sustainability of economic development in the digital era. The study concludes that while digitalization and FDI are key drivers of growth, optimizing their benefits requires coordinated policy support, particularly in workforce development and local investment ecosystems
PERSONAL DATA PROTECTION ON INTERNATIONAL DIGITAL TRADE: HARMONIZING STATE REGULATIONS THROUGH A COMMON STANDARD
No full textThe advancement of digital trade has brought considerable benefits, yet it also presents significant challenges, particularly in protecting users’ personal data. Digital trade platforms commonly require users to share personal information, raising concerns over data security and accountability. Current regulations governing personal data protection are primarily limited to national or regional legal systems, resulting in a lack of harmonization that impedes the seamless flow of international trade. This paper explores the pressing need for a standardized global framework for personal data protection within the digital trade landscape. Using a normative juridical approach, the study examines various regional legal regimes and assesses the relevance of international trade principles in addressing data protection issues. The analysis highlights the absence of a globally recognized standard for personal data protection in digital trade and finds that existing international instruments are inadequate for meeting current challenges. Given UNCITRAL’s role in shaping international trade law, the development of a new legal framework, such as a Model Law, should be pursued. As a form of soft law, a Model Law offers a practical and adaptable tool for harmonizing legal standards across jurisdictions. Its adoption would enhance legal certainty and ensure the protection of personal data in international digital trade transactions, thereby upholding the rights of all parties involved

Hot asphalt mixtures require aggregate as the constituent material. In this study, the potential for glass waste to be used as an aggregate substitute is examined. For this reason, a mixture design was determined to obtain the Optimum Asphalt Content of the Asphalt Concrete-Binder Course mixtures using glass waste as a substitute for fine aggregate. The glass waste used is glass waste that passes through sieve No. 50 and retained on sieve No.100. The proportion of glass waste substitution is 0%, 25%, 50%, 75%, and 100% to the amount of fine aggregate in the mixture. The asphalt mixture in this study was made using the Marshall mixture design method. From this design, the Optimum Asphalt Content is obtained at 5.9% (0% glass waste), 5.4% (25% glass waste), 5.2% (50% glass waste), 5.1% (75% glass waste), and 4.9% (100% glass waste). Next, test spe-cimens were made for Indirect Tensile Strength testing, and carried out for testing in dry and wet conditions, and the Tensile Strength Ratio of the test specimens was determined. The Tensile Strength Ratio of the asphalt mixture decreases with increasing proportion of glass waste and decreasing asphalt content. Overall, this research shows that glass waste can be used as a substitute for fine aggregate. Keywords: hot mix asphalt; aggregate; glass waste; Marshall Method; Tensile Strength Ratio
