Abstract

This study examines changes in the Normalised Difference Vegetation Index (NDVI) for Serang City between 2019 and 2023 to quantify vegetation density and health in the face of urbanization. Using Sentinel-2 satellite data and GIS analysis, it investigates how urban development, climate change, and land use influence plant cover. The findings indicate a substantial decrease in high vegetation from 13,089.791 hectares in 2019 to 12,296.742 hectares in 2023, accompanied by increases in tiny vegetation and aquatic zones. Statistical experiments show that urban expansion is a significant cause of vegetation loss, with climate changes impacting sparsely vegetated areas. This study emphasizes the dynamic interplay between urban expansion and climate conditions in generating vegetation trends, providing essential information for urban planners and politicians. The results demonstrate the necessity for focused reforestation and sustainable urban development to save green places, enhance environmental quality, and alleviate the adverse effects of urbanization. Immediate urban planning initiatives are recommended to combat vegetation loss, promote sustainable development, and increase resistance to environmental change.

Abstract

Arbuscular mycorrhizal fungi (AMF) form mutualistic interactions with plants, including Cynometra cauliflora (Namnam), a tropical indigenous species from the Fabaceae family. This study explores the educational potential of this biological relationship to enrich high school biology education under the Kurikulum Merdeka framework. Field research was conducted at PT Chandra Asri’s Biodiversity Park in Cilegon, Banten Province, Indonesia, an area with rich local biodiversity and a tropical rainforest climate.  The study used a qualitative content analysis approach following an exploratory-descriptive model. Nine naturally growing C. cauliflora individuals were selected for morphological observations and root sampling. Morphological characteristics were documented following standard botanical protocols, while AMF colonization was assessed through root clearing, Phillips and Hayman staining method, and microscopic observation. The percentage of AMF colonization was calculated using the gridline intersect method. Habitat characterization to understand the ecological context. Curriculum analysis reviewed Indonesian biology standards, textbooks, and scientific literature to map potential integrations. Key concepts such as mutualism, nutrient cycling, biodiversity conservation, and plant physiology were identified for curriculum enrichment. The findings suggest that studying C. cauliflora and its AMF association can effectively support Capaian Pembelajaran (Learning Achievement Targets), fostering student skills in scientific methods, environmental awareness, and critical thinking. Incorporating local examples promotes contextual and inquiry-based learning, aligning with the spirit of the Kurikulum Merdeka and strengthening students’ ecological literacy. In conclusion, the mutualistic relationship between C. cauliflora and AMF offers a valuable, locally relevant scientific model for enhancing biology education. It bridges scientific knowledge, cultural understanding, and sustainability, preparing students for real-world ecological challenges.

Abstract

Understanding the characteristics of domestic wastewater is crucial for designing effective wastewater treatment facilities that comply with regulatory standards. This study examined key parameters, including pH, BOD, COD, TSS, oil and grease, ammonia nitrogen, and total coliform, outlined by Indonesia’s Ministry of Environment and Forestry (MoEF) under their regulation. Samples were collected monthly over a 12-month period from three types of facilities: shopping centers, office buildings, and hospitals. The results indicated significant variability among the sites. The shopping center recorded the highest concentrations of BOD and TSS, with values of 231 mg/L and 366 mg/L, respectively, while the hospital showed elevated COD levels, reaching 725 mg/L. Its processing requires a wastewater treatment plant that aims to reduce various parameters that exceed the threshold based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.68 /Menlhk/Setjen/Kum I/8/2016 on Domestic Waste Quality Standards. These findings underscore the need for tailored wastewater treatment approaches based on facility type to mitigate environmental impacts and maintain water quality standards.

Abstract

Vaname shrimp (Litopenaeus vannamei) aquaculture plays a crucial role in the fishery commodities to enhance the economy in Indonesia. The development of Vaname shrimp culture in Bengkunat Coastal Lampung has a strong potential due to its extensive coastline. To support the high demand of vaname shrimp, the intensive shrimp method can address this solution. However, intensive culture has a high distribution of shrimp requires large amounts of feed, that contributes to organic pollution in the water. Therefore, this study aims to determine the characteristics of shrimp farming residual water based on variations in shrimp ages to develop wastewater management strategies. This study was conducted from January 16 to March 12, 2024 at Lumintu shrimp pond in Bengkunat. This research is an exploratory descriptive study with a qualitative approach to assess the total of ammonia, nitrite, total organic matter (TOM), total bacterial abundance (TBC), and total vibrio bacteria (TVC). In conclusion, the study indicates that ammonia, nitrite, total bacterial count (TBC), and total Vibrio count (TVC) are within acceptable ranges. However, total organic matter (TOM) surpasses safe levels for shrimp ponds.

Abstract

This study examines the variation of Particulate Matter levels in eight work areas and evaluates the correlation between Particulate Matter levels and measurement time. The observed areas include starch warehouse, starch damping, coal storage, finished goods, load out, maintenance workshop, chemical warehouse, and bagging house. Data collection was conducted periodically over six quarters from 2021 to 2022. The analysis results showed significant variations in Particulate Matter levels between work areas. A strong positive correlation was found in the ‘load out’ area (r=0.791), but it was not statistically significant (p=0.061). In contrast, the ‘starch warehouse’ area showed a strong negative correlation (r=-0.662), but was also not significant (p=0.152). The use of ChatGPT Plus in this study facilitated data analysis and prediction of Particulate Matter levels. This Artificial Intelligence technology is able to process historical data, perform exploratory analyses, and develop prediction models such as AutoRegressive Integrated Moving Average and linear regression. Further research with long-term data is needed to understand the dynamics of air pollution in industrial environments. This research contributes to the understanding of the impact of air quality on workers' health and demonstrates the potential use of AI technology in environmental data analysis and air pollution prediction.

Abstract

This study aims to examine the indications of a new currency project which is planned to be announced at the BRICS Summit in South Africa2023. The BRICS countries now account for 40% of the global population and a quarter of global GDP. PUse of Yuan has increased over recent years, accounting for 7% of global foreign exchange trading. While the US dollar continues to play a large role in the international financial system, including serving as the leading global reserve currency. US dominance is increasingly facing challenges from oil-producing countries, including Iran, andalsoWashington's longtime ally Saudi Arabia which announced that it would consider selling oil in currencies other than Dollar. The research uses the theory of International Monetary System and Counter Hegemony in understanding the problems that occur. This research uses a qualitative approach to explain a phenomenon in depth and examines more to the substance of the meaning of the phenomenon.The findings of this research are on the attitude of each BRICS member country, that although BRICS has a discourse for the global financial system, but no country seems to seriously intend to de-dollarize or make a real effort to find an alternative currency to replace the US dollar. The goal that is in the common interest of BRICS is not to replace, find an alternative to the dollar, or even for the purpose of lowering the value of the US dollar. The common goal is to control hegemony so that the US cannot arbitrarily exercise its political power for unilateral economic and military interests.
