Abstract

Climate change is a global problem characterized by increasing temperatures and environmental instability due to human activities, such as the use of fossil fuels and deforestation. This study aims to analyze the impact of climate change on tropical forests and provide scientific insights for effective mitigation. Qualitative descriptive methods were used with literature studies from journals, books, and other academic references. The results showed a significant increase in temperature in the tropical forests of East Kalimantan, reaching 0.95°C per decade, which disrupts the ecosystem, increases the risk of fire, and changes rainfall patterns. These changes, triggered by greenhouse gas emissions and decreased forest cover, exacerbate global warming and biodiversity loss. Mitigation efforts include reforestation, sustainable forest management, and international collaboration through the REDD+ program. These results emphasize the importance of forest conservation as a primary strategy for climate action.

Abstract

Global phenomena such as global warming and climate change have broad impacts, including the rapid development of invasive species that disrupt the balance of the ecosystem. One of the invasive species is Tempuyung (Sonchus arvensis). Although known as a weed, this plant has the potential as an anti-diabetic agent. This study aims to identify bioactive compounds in Sonchus arvensis that can inhibit the amylase enzyme in silico. The methods used include collecting data on the structure of the amylase enzyme and bioactive compounds, docking with PyRx, and residue analysis using BIOVIA Discovery Studio. The results showed that the Rhamnetin compound had the best binding affinity value (-8.6 kcal/mol), ideal RMSD (<2.0 Å), and the highest percentage of Binding Site Similarity (BSS) (100%). In addition, Luteolin-7-O-Glucoside also showed high inhibition potential. The conclusion of this study is that Rhamnetin and Luteolin-7-O-Glucoside in Sonchus arvensis have the ability to inhibit the amylase enzyme, making it a potential candidate as an anti-diabetic agent.

Abstract

The purpose of this study was to test and determine the concentration of Liquid Organic Fertilizer (LOF) from cow urine that is most effective for the growth of Lettuce (Lactuca sativa L.) plants. This type of research is experimental research. The research approach used is quantitative and qualitative. The research design used is Completely Randomized Design (CRD). The population in this study were all lettuce seedlings that had been sown. The sample used in this study was lettuce plants totaling 30 seedlings. The parameters observed were plant height and number of leaves of Lettuce (Lactuca sativa L.) plants. Furthermore, the data analysis used was one way ANOVA with the SPSS 21 for Windows program. The results of the study showed that the best dose of Liquid Organic Fertilizer (LOF) from cow urine was in the treatment of P2: 200 ml of POC from cow urine + 800 ml of water, which was to produce the highest plant height of 7.59 cm, and the treatment of P1: 100 ml of POC from cow urine + 900 ml of water produced the highest number of leaves, which was 5.30 strands.

Abstract

This study aims to examine effective coastal conservation strategies in preventing coral reef habitat loss in Indonesian waters. Coral reefs play a very important role in maintaining the balance of marine ecosystems, but they face serious threats, such as climate change, pollution, destructive fishing, and unsustainable exploitation of natural resources. Through this literature review, various conservation approaches that have been implemented in Indonesia, both community-based, government policies, and international initiatives, are analyzed to determine their effectiveness in protecting coral reefs. In addition, this study also explores the challenges faced in implementing conservation strategies and opportunities to strengthen collaboration between the government, communities, and the private sector. The results of this study are expected to provide useful recommendations in the development of more holistic conservation policies and strategies to protect and restore coral reef ecosystems in Indonesia.

Abstract

This research aims to analyze the dominance of starfish species in the Pantai Awang area, Central Lombok Regency. The type of this research is exploratory descriptive research. This study uses purposive sampling method with 3 stations, 5 transects, and 4 plots. The data collection techniques used were observation and documentation. The data analysis technique used is the dominance index. The results of the research conducted show that the highest dominance is found in the species Protoreaster nodosus, with a dominance index value of 0.857, categorized as moderate dominance, meaning there is light dominance where the development of species is quite balanced. Meanwhile, Archaster typichus and Linckia laevigata have dominance index values of 0.114 and 0.028, categorized as low dominance, meaning there is no dominance with balanced species development. Thus, it can be concluded that in the studied ecosystem, Protoreaster nodosus tends to be more dominant compared to Archaster typichus and Linckia laevigata, but there is no species that is so dominant as to disturb the balance of the ecosystem.
