Abstract

Climate change is one of the biggest challenges faced by ecosystems and biodiversity worldwide. This research examines climate change's impact on biodiversity through a comprehensive literature review. By collecting and analyzing various previous studies, this research identifies patterns of change in flora and fauna species in response to changing climate variables, such as temperature, rainfall, and the frequency of extreme weather events. Literature results show that many species experience changes in distribution, behavior and reproductive timing, which have the potential to disrupt ecosystem interactions and damage ecological balance. This research also discusses the impact of climate change on natural habitats and the conservation efforts needed to protect biodiversity. These findings highlight the urgency of taking effective mitigation and adaptation measures to maintain biodiversity amidst the increasing challenges of climate change.

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.

Abstract

This scoping review explores the roles of interleukin 1β, fibroblast growth factor, fibroblasts, keratinocytes, granulation tissue, and collagen density in the wound healing process, focusing on inflammation, proliferation, and remodeling phases. A systematic literature search identified studies investigating molecular and cellular mechanisms involved in wound repair. Findings reveal that fibroblast-derived exosomes carrying miR-93-5p inhibit autophagy, delaying diabetic wound healing. Controlled growth factor delivery enhances angiogenesis, fibroblast proliferation, and collagen deposition, accelerating tissue regeneration. SPRR1B+ keratinocytes facilitate rapid re-epithelialization, while granulation tissue provides essential scaffolding for cell migration and neovascularization. Elevated IL-1β impairs healing by increasing matrix metalloproteinases, degrading collagen. Natural compounds like red fruit oil and Binahong leaf extract promote angiogenesis and collagen synthesis. Genetic variations in inflammatory cytokines influence healing outcomes, indicating potential for personalized therapies. This review consolidates current evidence, providing insights into cellular and molecular interactions critical for effective wound repair and guiding future regenerative medicine strategies.

Abstract

Tilapia (Oreochromis niloticus) is one of the most widely cultivated freshwater fish in Indonesia, due to its high consumption rate and ease of maintenance. However, ectoparasite infection is a serious threat to fish health and productivity. This study aims to identify the presence and types of ectoparasites in Tilapia at the Fish Seed Center (BBI) of Aik Bukak Village, North Batukliang District, Central Lombok Regency. A total of 20 Tilapia samples from five parent ponds were examined using native scraping and biopsy techniques. The results of the analysis at the Histology and Pathology Laboratory, Faculty of Veterinary Medicine, Mandalika Education University, showed that 18 of the 20 samples were infected with ectoparasites. Morphological identification showed two types of parasites, namely Gyrodactylus sp. (Monogenea) and Trichodina sp. (Protozoa), which were found on the gills, mucus, and scales of the fish. These results indicate that ectoparasites are still a major problem in Tilapia cultivation at the research location.
