Kebudayaan Maritim, Perdagangan, dan Sistem Ekonomi Barter di Kampung Nelayan Hamadi Papua
Get PDFPapua is rich in local wisdom, reflected in its traditional economic systems, social structures, and maritime culture. One area demonstrates this richness is the Hamadi Fishing Village in Jayapura, inhabited by coastal communities such as the Tobati-Enggros and Nafri peoples. This study aims to examine three main aspects of life in the Hamadi Fishing Village—namely the barter system, the role of ethnic groups in trade, and maritime culture—in order to understand how local wisdom contributes to strengthening economic resilience, cultural identity, and adaptability to changing times. This research employs a descriptive qualitative approach, using data collection methods such as semi-structured interviews with community leaders and online literature review. The findings indicate that the barter system still exists, particularly in contexts where access to cash is limited, and as a means of fostering strong social relations between communities. Furthermore, the role of ethnic groups in trade—especially in cross-border activities with Papua New Guinea—reveals a distribution system based on kinship ties and customary norms that emphasize fairness and mutual benefit. The strong maritime culture of the Hamadi community is also a defining feature, where the sea is regarded as a sacred living space and primary source of livelihood
Ketatanegaraan dan Politik Luar Negeri Indonesia pada Masa Kabinet Djuanda
Get PDFThis article explores the political structure and foreign relations of Indonesia during the tenure of the Djuanda Cabinet (1957–1959), the last cabinet under the parliamentary system within the era of Liberal Democracy. Employing a qualitative descriptive approach and drawing on literature review, the study investigates the political instability, regional dissent, and institutional frameworks that shaped this period. The Djuanda Cabinet confronted serious issues such as regional uprisings (notably PRRI and Permesta), the introduction of President Sukarno’s concept of Guided Democracy, and internal party disputes. One of its most significant contributions was the 1957 Djuanda Declaration, which asserted Indonesia’s maritime boundaries as 12 nautical miles from the outermost islands, thus transforming the archipelago into a unified national territory. Despite facing resistance from Western powers, this declaration became the legal basis for Indonesia’s maritime claims and was later legitimized through the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Ultimately, the Djuanda Cabinet was instrumental in redefining Indonesia’s national borders and asserting its sovereignty at sea, while also signaling the close of the nation’s experiment with parliamentary democracy

OPTIMIZING FACILITIES AND INFRASTRUCTURE IN SCIENCE LEARNING: CHALLENGES, OPPORTUNITIES, AND SOLUTIONS THROUGH EBOOKS, LEARNING VIDEOS, LABORATORIES, AND TEACHING AIDS
Get PDFThis study presents a literature-based analysis focusing on the procurement and optimization of educational facilities and infrastructure, particularly in the context of science education. To improve the efficiency and efficacy of the teaching and learning process, the research attempts to identify important issues and offer workable solutions pertaining to the use of eBooks, instructional videos, labs, and teaching aids. Even though infrastructure and facilities are essential to a quality education, science courses are not making the most of them due to issues like inadequate digital resources, subpar lab equipment, and a lack of instructional media. The results demonstrate that maximizing the infrastructure for science education necessitates a multipronged strategy that includes the incorporation of suitable educational technologies, the supply of practical teaching tools, and ongoing professional development for teachers. Furthermore, to guarantee fair access and the long-term viability of educational resources, government participation through encouraging policies and consistent investment is essential. By tackling these issues, science instruction can become more dynamic, captivating, and capable of generating students who are competent and scientifically literate
