<![CDATA[The increase in the agricultural sector is supported by the use of pesticides to kill pests and diseases in plants. However, the continuous use of pesticides in excessive amounts can have a detrimental impact on the environment, especially the waters around agricultural land. Therefore, efforts are needed to degrade pesticide residues containing triadimefon compounds that pollute the environment such as sonolysis, ozonolysis, and sonozoisis methods. These three methods are organic compound degradation methods that utilize OH radicals to degrade organic compounds. Based on the data obtained, the sonolysis method with the addition of TiO2-anatase catalyst produced a degradation percentage of 76.25% after degradation for 150 minutes. While in a much shorter time, namely 15 minutes, using the ozonolysis method without the use of a catalyst, triadimefon can be degraded by 69.10%, and 71.87% with the sonolysis method. Since only a small amount of triadimefon is degraded by the sonozolysis method, it is more effective to use the ozonolysis method to degrade this triadimefon compound.]]>

<![CDATA[Indonesia is a country with a large area of water, with enormous potential for marine biodiversity which is useful as food, pharmaceuticals and cosmetics. There are several marine biota that produce secondary metabolites that are beneficial to humans, including microorganisms, blue green algae, green algae, brown algae, red algae, sponges, coelenterates, bryozoans, molluscs and sea cucumbers (echinoderms). Sea cucumbers are marine animals classified in the phylum Echinodermata, class Holothuroidea. This animal lives on sandy substrates or can be found in coral ecosystems. Sea cucumbers have complete and quite high nutritional content, but the existence of sea cucumbers with a high population in East Flores Regency has not been utilized properly. This study aims to identify and analyze the nutritional content of Sand Sea Cucumber (Holothuria Scabra) and Black Sea Cucumber (Holothuria Edulis). Identification is based on morphology and body color and spicules of the dorsal integument tissue, while the analysis of nutritional value includes water content and ash content using the gravimetric method, protein content using the Kjeldahl method, fat content using the Soxhlet method and carbohydrate content using the by difference method. The results of the study showed that the nutritional content of Sand Sea Cucumber (Holothuria Scabra) was 5.472% water content, 51.056% ash content, 27.072% protein content, 1.449% fat content and 20.424% carbohydrate content, while the nutritional content of Black Sea Cucumber (Holothuria Edulis) was 6.214% water content, 18.864% ash content, 51.636% protein content, 0.659% fat content and 28.841% carbohydrate content.]]>

<![CDATA[In urban and industrial regions, noise pollution is becoming a bigger environmental issue, particularly around airports. Excessive noise can have a number of detrimental effects on people's physical and mental well-being. The World Health Organization (WHO) states that extended exposure to noise can raise blood pressure, cause sleep disruptions, cause hearing loss, and increase the risk of cardiovascular disease. The fast expansion of air travel and heightened airport operations in Indonesia have made the noise issue worse. A lot of study has been done on how to lessen airport noise. More environmentally friendly natural solutions, such as the use of plants as noise barriers, have attracted attention as effective and sustainable alternatives. It is hoped that this research can provide practical and effective solutions that not only reduce noise but also support environmental sustainability. Thus, the results of this research will provide long-term benefits for the community around the airport and educational institutions such as the Indonesian Aviation Academy Banyuwangi. With an average noise reduction percentage of 46.79%, the study's results demonstrate the most notable decrease in noise levels. With a noise reduction of 29.54%, Tunas Merah comes in second. With a noise reduction of 23.94%, the TFan spruce comes in third. Noise is only decreased by 17.77% in the absence of barrier plants.]]>

<![CDATA[Tuberculosis is a highly prevalent disease among individuals. The bacteria may enter the human body with inhaled air, after which they will be taken into the lungs, and then might disseminate from the lungs into the other parts of the body via the circulatory system, lymphatic system, respiratory tract-bronchi, or by direct passage to other areas. The most affected organs with tuberculosis are the lungs, but it may also affect other organs, including the meninges, bones, superficial glands, and other organs. They include: India, 26%; Indonesia, 8.5%; China, 8.4%; the Philippines, 6%; Pakistan, 5.7%; Nigeria, 4.4%; Bangladesh, 3.6%; and South Africa, 3.6%. These eight countries account for two-thirds of the global cases put together. 8.2% of tuberculosis cases are co-infected with HIV. Targeted by the national tuberculosis control program is the elimination of tuberculosis by 2035 and attainment of a tuberculosis-free status by 2050. Methods: This study is based on a review of general clinical practice guidelines, research publications, websites, and textbooks on pulmonary tuberculosis. Findings and Analysis: There are various research writings about the clinical presentations of the condition, confirmatory investigations for Mycobacterium tuberculosis, the epidemiology of the patients, and risk conditions that predispose a patient to getting infected by the bacteria. Therapeutic interventions and pharmacological adverse effects. Conclusion Pulmonary tuberculosis is a communicable disease, and Indonesia still has a population that carries this infection. Thus, prevention of the disease should be done by every single individual in society by understanding and knowing the character of the disease.]]>

<![CDATA[This study investigated the effectiveness of three types of urban plants Pucuk Merah, Cemara Kifan, and Furing as noise barriers around airports. Using a 2-inch diameter sound tunnel along 6 meters with 3 mm PVC material, noise measurements were made at several points along the tunnel. The results showed that Furing plants had the most significant decrease in noise levels with an average noise reduction percentage of 46.79%. Pucuk Merah and Cemara TFan showed noise reductions of 29.54% and 23.94% respectively. Without the plant barrier, noise was only reduced by 17.77%. The characteristics of thick and dense leaves, as well as the complex structure of the plant, make Furing the most effective noise barrier. These results suggest that the use of plants, particularly furing, as a natural barrier around airports can significantly reduce the negative impact of noise and create a more comfortable environment.]]>

<![CDATA[Environmental microbiology is a critical field that explores the intricate relationships between microorganisms and their environments. This study investigates the roles of microorganisms in various environmental contexts, focusing on their diversity, abundance, and ecological functions. Samples were collected from agricultural soils, freshwater bodies, industrial wastewater, and urban air, and analyzed using culture-based and molecular techniques. The results revealed significant variations in microbial abundance and diversity across the sampled environments. Agricultural soils exhibited the highest microbial abundance and diversity, with nitrogen-fixing bacteria playing a crucial role in nutrient cycling. In contrast, freshwater bodies showed moderate diversity, while industrial wastewater had the highest abundance but lower diversity, with a high prevalence of hydrocarbon-degrading microorganisms. Urban air samples had the lowest abundance but relatively high diversity. The biochemical capabilities of the isolates further emphasized the ecological roles of these microorganisms, particularly in bioremediation and soil fertility. The findings underscore the importance of preserving microbial diversity for maintaining ecosystem health and resilience. This research highlights the need for integrating microbiological insights into environmental management policies and suggests future research directions to explore microbial interactions and their potential applications in biotechnology and environmental remediation.]]>
