Abstract

This article reports on a community service program conducted by students of UIN Raden Intan Lampung in Kubu Perahu Village, Balik Bukit District, aimed at addressing plastic waste issues through the utilization of ecobrick technology. The program included awareness-raising about the impacts of plastic waste, training in ecobrick paving block production, and the implementation of ecobrick products in village infrastructure development. The results indicate an increased awareness among the community regarding plastic waste management and new skills in ecobrick production. A total of 1,500 ecobrick paving blocks were produced and used to improve footpaths and public areas within the village. This program not only reduced the volume of plastic waste but also enhanced the environmental and infrastructural quality of the village. The success of this program demonstrates that community-based approaches and eco-friendly technologies can effectively address plastic waste issues and provide sustainable benefits to the community

Abstract

This study examines the competitive dynamics in Southeast Asia under the frameworks of the Belt and Road Initiative (BRI) and the Free and Open Indo-Pacific (FOIP), two key strategies reshaping the region’s geopolitical and economic landscape. Using a qualitative approach supported by extensive literature review, the research applies Kenneth Waltz's Power Balance Theory to analyze this rivalry. The BRI has accelerated infrastructure development and regional connectivity, strengthening economic ties between China and Southeast Asian nations. However, it raises concerns over economic dependence and the potential for China to exert undue political influence. On the other hand, the FOIP seeks to counterbalance China’s influence by enhancing alliances and security partnerships led by the United States and its allies. This rivalry creates a complex scenario for Southeast Asian countries, requiring them to navigate economic opportunities while addressing geopolitical risks. The study highlights how these initiatives influence foreign policy strategies across the region and their broader implications for stability and security. By exploring the interplay of economic and strategic factors, the research deepens understanding of Southeast Asia’s evolving power dynamics and provides insights into managing the challenges posed by these competing frameworks. This analysis enriches the discourse on the region’s critical role in a contested global order.

Abstract

Harmful Algal Bloom (HAB) is an ecological phenomenon that has been increasingly occurring in the Java Sea and has the potential to significantly affect marine productivity. However, studies that integrate multiple HAB triggering factors and their impacts on marine productivity in the Java Sea remain limited and largely fragmented. This study aims to analyze the influence of HAB on marine productivity in the Java Sea through a literature review approach. A total of 20 scientific articles published between 2015 and 2025 were analyzed, consisting of 6 primary articles and 14 supporting articles, with the main focus on coastal areas of the Java Sea. The review results indicate that the primary drivers of HAB occurrence in the Java Sea include increased nutrient concentrations (nitrate and phosphate), changes in oceanographic conditions (temperature, salinity, and current dynamics), and anthropogenic pressures in coastal regions. Dominant HAB-forming phytoplankton species were reported from the Dinoflagellata and Bacillariophyceae groups, which under certain conditions may quantitatively enhance marine productivity; however, this increase is considered pseudo-productivity due to subsequent declines in dissolved oxygen, disruption of food web structures, and elevated risks of toxicity to aquatic organisms. The novelty of this study lies in the integrated synthesis of the relationship between HAB drivers and their implications for marine productivity within the Java Sea. These findings emphasize that increased water fertility does not necessarily correspond to enhanced marine productivity, highlighting the importance of nutrient and coastal activity management to ensure the sustainability of the Java Sea ecosystem.
