Abstract

Climate change has become a crucial environmental issue in various sectors, including educational institutions. This study aims to analyze total carbon emissions from campus activities based on Scope 1 data, which includes generator set data and campus bus operations (2023). Scope 2 consists of electricity bill data (January-December 2023) obtained from the institution. The study uses a quantitative approach with emission calculations based on secondary energy consumption data and transportation activities, as well as carbon absorption estimates based on vegetation tree species and age identification. The results show that the total carbon emissions from campus activities in 2023 can reach 969,217.03 KgCO₂/year. Meanwhile, the emission absorption capacity of existing vegetation only reaches 774,546.11 KgCO₂ per year. Thus, there are residual emissions of 194,670.92 KgCO₂ per year that are not absorbed. The carbon tax calculation of IDR 30.00 per kg of CO₂, according to the prevailing regulations in Indonesia, provides an economic picture of IDR 5,840,127.6 per year for campuses. This finding indicates that campus vegetation has not fully offset the resulting carbon footprint and serves as an important basis for developing emission mitigation strategies towards a more sustainable campus.

Abstract

Background: Microplastics are the smallest particles of plastic measuring about 4.8 milliliters and are dangerous to the body due to the chemicals they contain, such as PCBs (Polychlorinated Biphenyls). Microplastics have been identified in various studies, both in aquatic and terrestrial environments, raising concerns about contamination in seafood, beverages (like beer), and more recently, bottled mineral water. Methods: This publication compiles and discusses currently available literature data on microplastic particles found in bottled mineral water. Findings: The discovery of microplastics in bottled mineral water highlights the widespread contamination of microplastics in consumable products, emphasizing the importance of water intake for supporting body metabolism. Conclusion: The identification of microplastics in bottled mineral water underscores the need for greater awareness of the dangers of microplastic contamination and its potential health risks. Novelty/Originality of this article: This article uniquely highlights the underexplored presence of microplastics in bottled mineral water, emphasizing the health risks associated with chemical contaminants like PCBs, and calls for increased awareness and regulatory measures to protect consumer safety.
