Abstract

One solution to urban farming is hydroponic cultivation. Currently, the development of the world of agriculture, especially in the field of hydroponics, is increasingly rapid. When compared to conventional farming, hydroponics has advantages that conventional farming does not have. One plant that is often cultivated hydroponically is the cherry tomato plant. The growth and production of tomatoes with a good hydroponic system requires the right concentration and volume of nutrients. This research used a non-factorial randomized block design (CRD) with Nutrient concentration (N) treatment, consisting of 5 levels, namely: N1 = 800 ppm, N2 = 900 ppm, N3 = 1000 ppm, N4 = 1100 ppm and N5 = 1200 ppm. The results showed that nutrient concentration had an effect on the generative growth phase, but had no significant effect on the vegetative growth phase of cherry tomato plants. Nutrient concentration influences the morphology and physiology of cherry tomato plants. Nutrient concentration had a significant effect on the production of cherry tomato plants hydroponically with the heaviest fruit weight per plant found in the AB Mix nutrient concentration of 1000 ppm (N3) of 97.89 g.

Abstract

The pace of global environmental change and the intensification of human activities have put significant pressure on marine ecosystems, threatening the sustainability of many species that are important both for ecosystems and the economies of coastal communities. In this context, this study aims to evaluate the application of genetic technologies in the conservation of endangered marine species, focusing on environmental DNA (eDNA) monitoring, CRISPR genetic engineering techniques and population genetic analysis. The method used was a literature review that examined current academic sources related to genetic technologies and their implementation in conservation. Findings show that eDNA is a highly effective tool in species and habitat monitoring, and has been successful in specific cases such as Napoleon fish and green turtles in Raja Ampat. In contrast, CRISPR techniques offer the potential to improve the genetic resilience of species, despite significant regulatory and ethical challenges. The implications of this study emphasize the need for strong policy support and international collaboration to address these challenges and optimize the use of genetic technologies in more effective conservation strategies in the future.

Abstract

Crisis aquatic biodiversity is a critical environmental issue, triggered by human activities such as overfishing, pollution, and climate change, which have serious impacts on the stability of ecosystems and the climate change, which has serious impacts on the stability of ecosystems and the livelihoods of coastal communities. livelihoods of coastal communities. This research aims to examine community-based solutions in restoring degraded aquatic ecosystems, with a focus on the integration of sustainable aquaculture technologies and aquaponic systems. The methodology used was a comprehensive literature analysis of scientific articles, journals and relevant publications. The research findings show that sustainable fisheries management, habitat restoration, environmental education and awareness, implementation of environmentally education and environmental awareness, the application of environmentally friendly technologies, and the development of supportive policies are the main strategies for sustainable fisheries management. development of supportive policies are key strategies in improve conservation effectiveness. The implications of this research show that a community-based approach is not only effective for the conservation of aquatic biodiversity, but also provides practical guidance for policymakers and non-governmental organizations in designing and implementing community-based policy makers and non-governmental organizations in designing and implementing more holistic and effective ecosystem restoration programs that are more holistic and sustainable.
