Abstract

Mycorrhizal fungi play a crucial role in forest ecosystems, facilitating nutrient uptake and enhancing plant health. These symbiotic relationships are vital for the resilience and productivity of forests, yet their contributions to ecosystem health remain underexplored. This study aims to investigate the specific roles of mycorrhizal fungi in promoting forest ecosystem health by assessing their impact on nutrient cycling, soil structure, and plant diversity. A combination of field surveys and laboratory analyses was employed, focusing on various forest types with differing mycorrhizal associations. Data were collected on soil properties, fungal biodiversity, and plant growth metrics. The results indicate that forests with diverse mycorrhizal communities exhibit improved soil health, characterized by higher nutrient levels and better moisture retention. Additionally, these forests support greater plant diversity and demonstrate enhanced resilience to environmental stressors. The findings underscore the importance of mycorrhizal fungi in maintaining forest ecosystem health and highlight the need for conservation strategies that protect these critical organisms. In conclusion, mycorrhizal fungi are essential for nutrient cycling and overall forest vitality, suggesting that their preservation should be a key component of forest management practices.

Abstract

Air pollution remains a critical global issue, largely due to emissions from vehicles. Catalytic converters play a vital role in reducing harmful pollutants, but their efficiency can be improved through innovative materials. Nanomaterials have emerged as promising candidates for enhancing catalytic converter performance. This study aims to investigate the application of nanomaterials in catalytic converters to improve their efficiency in reducing harmful emissions. The research focuses on identifying specific nanomaterials that can enhance catalytic activity and longevity. A comprehensive review of existing literature on nanomaterials used in catalytic converters was conducted. Laboratory experiments were performed to evaluate the catalytic performance of various nanomaterials, including metal nanoparticles and nanocomposites, in simulated exhaust conditions. Emission measurements were analyzed to assess effectiveness. Findings indicate that the incorporation of nanomaterials significantly enhances the catalytic activity of converters. Metal nanoparticles demonstrated improved oxidation and reduction reactions, resulting in higher conversion rates of NOx, CO, and unburned hydrocarbons. The study also identified optimal concentrations and combinations of nanomaterials for maximum efficiency. This research highlights the potential of nanomaterials to transform catalytic converters and improve air quality.

Abstract

The rapid development of Internet of Things (IoT) technology offers significant opportunities for improving livestock management, especially in dairy farming systems in developing countries like Indonesia. Traditional methods of monitoring dairy cow health, behavior, and estrus cycles rely on manual observation, which can be time-consuming, subjective, and inaccurate. These limitations lead to delayed disease detection, suboptimal reproductive performance, and reduced milk productivity. This study aims to design and evaluate an IoT-based wearable sensor system for continuous monitoring of dairy cow health, rumination patterns, and estrus cycles in Indonesian dairy farms. A research and development approach combined with field testing was employed. The system integrates wearable sensors attached to cows, collecting data on movement, body temperature, and rumination activity. Data is transmitted in real-time via IoT networks to a cloud platform for processing and visualization. System performance was assessed through accuracy testing, reliability analysis, and farmer feedback. The results show that the system effectively detects changes in rumination behavior, identifies early health issues, and predicts estrus cycles with high consistency compared to traditional methods. Farmers reported improved decision-making efficiency and reduced labor intensity. The IoT-based wearable sensor system demonstrates potential as an innovative solution for enhancing dairy cow health monitoring and reproductive management in Indonesia, supporting sustainable dairy farming practices.
