Abstract

This research aims to examine the contribution of natural resources (NR) to Indonesia’s national economy. The study employs a descriptive qualitative method with Indonesia as a case study, using secondary data obtained from official government publications, the Central Bureau of Statistics (BPS), the Ministry of Energy and Mineral Resources, as well as relevant academic literature. The findings indicate that natural resources play a significant role in supporting gross domestic product (GDP), exports, state fiscal revenues, and employment, both directly and indirectly, through multiplier effects on the transportation, logistics, and financial services sectors. Overall, the study concludes that natural resources remain a key driver of national development; however, they must be managed with principles of sustainability, equitable distribution of benefits, and technological advancement.

Abstract

Indonesian plays a vital role as the nation's unifying language and official means of communication. This study aims to examine the role of Indonesian language proficiency in supporting social and economic development, particularly in education, community participation, and national competitiveness. The method used is qualitative through literature study, document review, interviews, and observation. The results show that Indonesian language proficiency directly impacts the quality of education because it supports the learning process and produces superior human resources. Indonesian also strengthens social cohesion, increases community participation, and opens wider access to employment. In the economic sector, good language skills improve workforce competence and the effectiveness of business communication between regions. However, challenges remain, such as disparities in the quality of language education, low interest among the younger generation, and the influence of foreign languages. Therefore, improving Indonesian language proficiency needs to be a national strategic agenda to strengthen national identity, expand access to development, and enhance global competitiveness.

Abstract

This study aims to examine how conglomerate mergers can be used as a strategy to strengthen market power through the implementation of product differentiation. Using a qualitative approach and case study method on several national and international companies such as the Disney-Fox merger and Indosat Ooredoo Tri, this study focuses on understanding post-merger product differentiation strategies in strengthening the company's competitive position in the market. The analysis results show that conglomerate mergers have two main functions: first, as an instrument for market expansion and increasing company value through innovation, bundling strategies, and strengthening brand image; second, as a means to create barriers to entry and increase switching costs for consumers. The Disney-Fox case study emphasizes the importance of intellectual property ownership and exclusive content as strategic advantages in maintaining customer loyalty. Meanwhile, the Indosat Tri merger emphasizes infrastructure integration and digital service development as a form of service-based differentiation. Although conglomerate mergers can increase efficiency and strengthen a company's competitive position, potential risks such as increased market concentration and reduced consumer choice still need to be monitored. Therefore, the role of supervisory institutions such as the KPPU is crucial in ensuring that the implementation of mergers remains in accordance with the principles of fair competition and maintains a balance between the interests of business actors and consumer protection.

Abstract

Penelitian ini bertujuan untuk menganalisis dampak inflasi dan tingkat pengangguran terbuka terhadap investasi langsung asing (FDI) di Provinsi Sumatera Utara. Penelitian ini menggunakan metodologi kuantitatif dengan teknik deskriptif-verifikasi. Data yang dianalisis terdiri dari data deret waktu sekunder yang bersumber dari Badan Pusat Statistik (BPS) dan Badan Koordinasi Penanaman Modal (BKPM) periode 2001–2023. Penilaian dilakukan menggunakan model regresi linier berganda melalui perangkat lunak EViews, beserta uji asumsi tradisional untuk menjamin validitas model penelitian. Hasil analisis menunjukkan bahwa inflasi tidak terlalu berpengaruh terhadap FDI, sedangkan tingkat pengangguran terbuka memiliki dampak negatif yang signifikan. Hal ini menunjukkan bahwa kenaikan tingkat pengangguran dapat menurunkan minat investor asing untuk berinvestasi. Di saat yang sama, baik inflasi maupun tingkat pengangguran terbuka telah menunjukkan dampak yang cukup besar terhadap FDI. Model regresi yang diterapkan dalam penelitian ini dapat memperhitungkan sekitar 46,7% variasi perubahan FDI di Provinsi Sumatera Utara.

Abstract

This study aims to examine how digitalization impacts the quality of public services and the delivery of public goods in Indonesia, while identifying the factors that facilitate and hinder them. The approach used is descriptive qualitative, using a case study within a government agency such as the Medan Population Service. Data collection involved analyzing the policy document Presidential Regulation No. 95 of 2018, impact matrix tables, and process flow diagrams, using the Miles and Huberman analytical framework, which includes data reduction, presentation, and formulation of conclusions. The results show that digitalization significantly improves efficiency: service time is reduced from several days to 30 minutes, operational costs decrease by 40 percent due to transparent e-procurement, data accuracy reaches 98 percent, and public satisfaction increases by 82 percent due to the convenience provided by the SPBE and INA Digital applications. Transparency is increased with a 60 percent reduction in problematic procurement cases through real-time audits; However, issues such as inadequate internet infrastructure (20-30 percent effectiveness in rural areas), low digital literacy among the elderly, and concerns about data security continue to hamper the accessibility of public goods such as telemedicine and targeted social assistance.
