The Indonesian Green Technology Journal (IGTJ) is an international journal that publishes recent developments and emerging issues in both conceptual and experimental aspects of green and renewable technology. The Indonesian Green Technology Journal (IGTJ) publishes research results in the theoretical and experimental aspects of green science, engineering, technology, and medicine. Studies published in this journal include; Biomaterials, Green water management, Green energy development and management, Sustainable waste management, Green biotechnology, Green building and architecture, Clean production technology, Global warming technology, and Green building and architecture. This journal also emphasises the significance of green technology development, implementation, challenge, opportunity, and acceptance from an Indonesian perspective. IGTJ is publicly open for publication of review papers, short communication, and research papers. Since 2024, this journal has become an international journal and uses English for every paper that will be published.

Abstract

Water quality degradation remains a critical challenge in small-scale aquaculture, particularly due to the accumulation of suspended solids and ammonia from feed waste and metabolic excretion. This study aimed to evaluate the efficiency of a simple, eco-friendly filtration system using natural materials—sand, zeolite, pumice, and coconut fiber—in removing Total Suspended Solids (TSS) and ammonia (NH?–N). Four treatments were tested over a five-day period: P1 (sand and zeolite), P2 (pumice and coconut fiber), P3 (all four materials), and a control (no filter media). Each unit was constructed using low-cost containers and operated under continuous flow conditions. Results showed that P3 consistently achieved the highest removal efficiency, reducing TSS by 82.5% and ammonia by 83.3%. ANOVA and Tukey HSD tests confirmed significant differences (p < 0.05) among treatments. The combination of mechanical, chemical, and bioactive media in P3 enhanced both physical filtration and nitrogen removal. These findings support the application of natural-based filter media as a sustainable, low-cost solution for improving water quality in decentralized aquaculture systems, especially in resource-limited settings

Abstract

The derived motives of people in the drylands while performing woodfuel production are primarily to support their livelihoods and source of energy in dryland areas. Besides to its significant roles, it has also undoubted multiple negative effects. However, there is little information documented that would help policy and development interventionists to mitigate those effects. Therefore, this study assesses the deforestation and environmental implications of woodfuel production activity. The result shows that dependence on woodfuel (charcoal and firewood) income increases markedly from farming to pastoral groups, becoming the dominant income source for both agro-pastoral and pastoral households. This pattern underscores the critical role of woodfuel in rural livelihoods, especially where agricultural productivity is low. Poverty, unemployment, and the requirement for energy are main reasons of woodfuel dependency. However, woodfuel producers do not create their own plantations for the extraction of woodfuel. They merely rely on the forest resources to meet their requirements. Deforestation, soil loss, and loss of biodiversity were some of the environmental problems that arose from woodfuel production. The study result recommended a policy direction to support the adoption of sustainable woodfuel production practices such as plantations, assisting natural regeneration based on the local context of dryland areas
