Boosting Winter Green Travel: Prioritizing Built Environment Enhancements for Shared Bike Users Accessing Public Transit in the First/Last Mile Using Machine Learning and Grounded Theory
Authors: Du Yu , Ji Xian , Dou Chenxi , Wang Rui
Published: November 2024

Shared bikes are widely used in Chinese cities as a green and healthy solution to address the First/Last Mile issue in public transit access. However, usage declines in cold regions during winter due to harsh weather conditions. While climate factors cannot be changed, enhancing the built environment can promote green travel even in winter. This study uses data from Shenyang, China, to investigate how built environment attributes impact the travel satisfaction of shared bike users who utilize bikes as a First/Last Mile solution to access public transit in winter cities. By employing machine learning algorithms combined with Asymmetric Impact-Performance Analysis (AIPA) and grounded theory, we systematically identify the key attributes and rank them based on their asymmetric impact and urgency of improvement. The analysis revealed 19 key attributes, 17 of which are related to the built environment, underscoring its profound influence on travel satisfaction. Notably, factors such as the profile design of cycling paths and safety facilities along routes were identified as high priorities for improvement due to their significant potential to enhance satisfaction. Meanwhile, features like barrier-free access along paths and street greenery offer substantial opportunities for improvement with more modest efforts. Our research provides critical insights into the nuanced relationship between built environment features and travel satisfaction for First/Last Mile shared bike users. By highlighting priority improvements, we offer urban planners and policymakers a framework for creating livable, sustainable environments that support green travel even in harsh winter conditions.

Published: November 2024

This article presents the results of laboratory tests conducted to identify the granulometric stabilization and chemical improvement techniques used in an experimental segment of the unpaved BR-030 highway in the Maraú Peninsula, Bahia. The segment was designed to evaluate the performance of primary coating sections stabilized with sand, clayey gravel, reclaimed asphalt pavement (RAP), and simple graded crushed stone (GCS), as well as chemically improved with Portland cement and hydrated lime. The laboratory campaign focused on mechanical resistance, resilient modulus, and permanent deformation tests. In this research, chemical improvement with the addition of 2% Portland cement presented the most promising results for potential application in the section of the BR-030 highway intended to remain unpaved. Additionally, a life cycle assessment (LCA) revealed that mechanical stabilization of the primary coating has the lowest environmental impacts, making it a suitable and sustainable option among stabilization methods.

Published: November 2024

This study presents a sustainable solution for the removal of the emerging contaminant chloroquine from aqueous solutions, utilizing biochar synthesized from cassava waste through a rapid, single-step microwave activation process. By repurposing cassava waste, a prevalent agricultural by-product, this method aligns with circular economy principles, promoting the sustainable reuse of waste materials. Characterization of the biochar demonstrated a highly porous, crystalline structure optimized for adsorption applications. Adsorption studies demonstrated optimal performance at 45 °C, with a maximum adsorption capacity of 39 mg g−1 in the Langmuir model. Thermodynamic analysis confirmed that the process was spontaneous, endothermic, and consistent with physisorption. Kinetic experiments revealed that 200 rpm agitation provided the most favorable conditions. Notably, the biochar demonstrated substantial reusability, maintaining up to 70% of its adsorption capacity over five desorption cycles. This sustainable adsorbent stands out as a practical, eco-friendly option for removing pharmaceutical contaminants while also corroborating with the beneficial reuse of agricultural by-products.

Published: November 2024

A better understanding of climate change impact on dry/wet conditions is crucial for agricultural planning and the use of renewable energy, in terms of sustainable development and preservation of natural resources for future generations. The objective of this study was to investigate the impact of climate change on temporal fluctuations of dry/wet conditions in Serbia on multiple temporal scales through multifractal analysis of the standardized precipitation evapotranspiration index (SPEI). We used the well-known method of multifractal detrended fluctuation analysis (MFDFA), which is suitable for the analysis of scaling properties of nonstationary temporal series. The complexity of the underlying stochastic process was evaluated through the parameters of the multifractal spectrum: position of maximum α0 (persistence), spectrum width W (degree of multifractality) and skew parameter r dominance of large/small fluctuations). MFDFA was applied on SPEI time series for the accumulation time scale of 1, 3, 6 and 12 months that were calculated using the high-resolution meteorological gridded dataset E-OBS for the period from 1961 to 2020. The impact of climate change was investigated by comparing two standard climatic periods (1961–1990 and 1991–2020). We found that all the SPEI series show multifractal properties with the dominant contribution of small fluctuations. The short and medium dry/wet conditions described by SPEI-1, SPEI-3, and SPEI-6 are persistent (0.5<α0<1); stronger persistence is found at higher accumulation time scales, while the SPEI-12 time series is antipersistent (0<α0−1<0.5). The degree of multifractality increases from SPEI-1 to SPEI-6 and decreases for SPEI-12. In the second period, the SPEI-1, SPEI-3, and SPEI-6 series become more persistent with weaker multifractality, indicating that short and medium dry/wet conditions (which are related to soil moisture and crop stress) become easier to predict, while SPEI-12 changed toward a more random regime and stronger multifractality in the eastern and central parts of the country, indicating that long-term dry/wet conditions (related to streamflow, reservoir levels, and groundwater levels) become more difficult for modeling and prediction. These results indicate that the complexity of dry/wet conditions, in this case described by the multifractal properties of the SPEI temporal series, is affected by climate change.
Rethinking the Smart Green City Project in South Korea: A Critical Juncture Approach
Authors: Kim Myunghee
Published: November 2024

Over the past 10 years, the Korean government has declared its intention to achieve carbon neutrality to the international community and strived to create smart cities and green cities as a practice to achieve carbon neutrality. In the same context, the Smart Green City project, which began in earnest at the end of 2020, initially attracted national attention due to the strong will of the administration. However, limitations in its performance were revealed. This study aimed to identify the policy mechanisms that led the Korean government to pursue the Smart Green City project using a critical juncture approach and to derive useful implications for policy selection. A critical juncture framework was applied for in-depth analysis, and a descriptive case study based on critical thinking was conducted. The results confirmed that endogenous and exogenous environmental changes surrounding the government at critical junctures were mechanisms for establishing the Smart Green City project. In addition, the government’s attempt to differentiate itself from the policies of previous governments was confirmed to be a constraint that actually hindered the project’s progress. This study concludes that if a government facing a complex crisis makes hasty policy decisions, it is likely to repeat the policy pattern or institutional path of previous governments. It also argued that in this situation, policy choices that aim to cut a new path may cause the government to choose a wrong path, which may have irreversible consequences.
Analyzing the Relationship Between User Feedback and Traffic Accidents Through Crowdsourced Data
Authors: Kim Jinguk , Jeon Woohoon , Kim Seoungbum
Published: November 2024

Identifying road segments with a high crash incidence is essential for improving road safety. Conventional methods for detecting these segments rely on historical data from various sensors, which may inadequately capture rapidly changing road conditions and emerging hazards. To address these limitations, this study proposes leveraging crowdsourced data alongside historical traffic accident records to identify areas prone to crashes. By integrating real-time public observations and user feedback, the research hypothesizes that traffic accidents are more likely to occur in areas with frequent user-reported feedback. To evaluate this hypothesis, spatial autocorrelation and clustering analyses are conducted on both crowdsourced data and accident records. After defining hotspot areas based on user feedback and fatal accident records, a density analysis is performed on such hotspots. The results indicate that integrating crowdsourced data can complement traditional methods, providing a more dynamic and adaptive framework for identifying and mitigating road-related risks. Furthermore, this study demonstrates that crowdsourced data can serve as a strategic and sustainable resource for enhancing road safety and informing more effective road management practices.

Authors: Wan Kai , Yu Xiaolin , Zou Kaiti
Published: November 2024

The spatial distribution and trend of carbon emissions in the Yellow River Basin—an important ecological barrier and economic belt in China—directly affect the stability of the ecosystem and the sustainable development of the regional economy. Based on the data for carbon emissions in China’s counties from 1997 to 2017, this paper utilizes standard deviation ellipses, Theil index nested decomposition, and geographic detector models to make a comprehensive description of the spatial and temporal distribution and dynamic evolution characteristics of carbon emissions in the Yellow River Basin. Factors influencing carbon emissions are also analyzed from multiple dimensions. According to the findings, (1) carbon emissions at the county level show a clear upward trend without reaching a peak, exhibiting a spatial distribution of higher emissions in the east and lower in the west and higher in the south and lower in the north, with the mid-lower reaches being the center. The junction of the Shandong, Shaanxi, and Gansu provinces further exhibits a significant expansion, forming two core areas of carbon emissions. (2) Carbon emissions at the county level in the Yellow River Basin are influenced by both economic and geographic factors, exhibiting a significant high carbon spillover effect and a low carbon lock-in effect. The gravity center of the distribution has shifted towards the mid-lower reaches, with the upper reaches displaying dispersion tendencies. (3) Intra-regional disparities are the main source of the overall spatial differences in carbon emissions, with the largest disparities being observed in the upper reaches, followed by the middle reaches, and the smallest disparities being observed in the lower reaches. Further analysis shows that the level of economic development is the primary factor influencing the spatial variation of carbon emissions, and the combined effects of population size and industrial agglomeration are the key drivers of the annual growth in carbon emissions.
Potential Reduction in Carbon Emissions in the Transport of Aggregates by Switching from Road-Only Transport to an Intermodal Rail/Road System
Authors: López-Acevedo Francisco Javier , Herrero María Josefa , Escavy Fernández José Ignacio , González Bravo José
Published: November 2024

Aggregates are the second-most consumed product in the world after water. This geological resource is used as building and construction material, and its production in quarries and delivery to customers generates several environmental problems. Their transport from quarries to consumption points, almost entirely done by truck, also generates impacts such as an increase in traffic and noise and the emission of greenhouse gases and other pollutants. Transportation and storage of goods account for 15% of greenhouse gas emissions in Europe and will increase significantly by 2050. To mitigate this, the European Union suggested shifting 30% of long-distance road freight to cleaner alternatives, such as rail or waterborne transport. This approach neglects the enormous volume of short-distance freight movement and its impact on achieving the goal of reducing greenhouse gas emissions. In this study, the hypothesis to test is whether the use of an intermodal rail/road transport mode, instead of just roads, for the transport of some products can help reduce global CO2 emissions even for short distances. To test this, this study investigates the carbon emissions (and transport cost reduction) generated by rail/road intermodal aggregate transport for short distances in the Madrid region (Spain), rather than the currently used direct truck transport. An analysis of variables, such as aggregate supply, demand locations and amounts, and road and rail networks, using a geographical information system provides the associated carbon emissions of the different transport alternatives. To obtain a reduction in CO2 emissions, this study proposes the establishment of intermodal transfer facilities near consumption centers, where materials are primarily transported by rail, with road transport limited to the final delivery to consumption areas. The results anticipate a notable decrease in carbon emissions in aggregate transport and allow the establishment of more efficient and environmentally friendly rail/road intermodal transport that would help to meet the goals of reducing climate change while making the use of aggregates more environmentally friendly.
The Competition Between Taxi Services and On-Demand Ride-Sharing Services: A Service Quality Perspective
Authors: Yang Jie , Wang Zeyu , Xu Chunming , Wang Di
Published: November 2024

On-demand ride-sharing services change our travel behavior, which threatens the survival of taxi services. Motivated by this, this paper examines the impact of on-demand ride-sharing services on taxi services and how to achieve the coexistence of two services from a service quality perspective. This paper analyzes the coexistence condition of two services considering the network effect. First, the profit target for taxi drivers is nonnegative. A Stackelberg model is built in which the taxi service is the leader and the on-demand ride-sharing service is the follower. Then, the reference dependency theory is introduced to modify the profit target of taxi drivers. And the new coexistence condition is compared with the benchmark status. The results find that the coexistence of the two services depends on the type of riders and the quality difference in both cases. When two services and riders are highly heterogenous, two services are more likely to coexist. Services with different qualities could better satisfy the diverse preferences of riders. Considering taxi profit without competition as the profit reference point, the requirement of service quality difference and the diversity of rider composition is increased. In terms of the network effect, the negative network effect is more beneficial to the coexistence of two services.
Medical and Engineering Applications for Estimation and Prediction of a New Competing Risks Model: A Bayesian Approach
Authors: Mohammad Hebatalla H. , Salem Heba N. , EL-Helbawy Abeer A. , Alamri Faten S.
Published: November 2024

The Bayesian approach offers a flexible, interpretable and powerful framework for statistical analysis, making it a valuable tool to help in making optimal decisions under uncertainty. It incorporates prior knowledge or beliefs about the parameters, which can lead to more accurate and informative results. Also, it offers credible intervals as a measure of uncertainty, which are often more interpretable than confidence intervals. Hence, the Bayesian approach is utilized to estimate the parameters, reliability function, hazard rate function and reversed hazard rate function of a new competing risks model. A squared error loss function as a symmetric loss function and a linear exponential loss function as an asymmetric loss function are employed to derive the Bayesian estimators. Credible intervals of the parameters, reliability function, hazard rate function and reversed hazard rate function are obtained. Predicting future observations is important in many fields, from finance and weather forecasting to healthcare and engineering. Thus, two-sample prediction (as a special case of the multi-sample prediction) for future observation is considered. An adaptive Metropolis algorithm is applied to conduct a simulation study to evaluate the performance of the Bayes estimates and predictors. Moreover, two applications of medical and engineering data sets are used to test and validate the theoretical results, ensuring that they are accurate, applicable to real-world scenarios and contribute to the understanding of the world and inform decision-making.

Published: November 2024

Convolutional Neural Networks (CNNs) are a class of deep neural networks that have proven highly effective in areas such as image and video recognition. CNNs typically include several types of layers, such as convolutional layers, activation layers, pooling layers, and fully connected layers, all of which contribute to the network’s ability to recognize patterns and features. The pooling layer, which often follows the convolutional layer, is crucial for reducing computational complexity by performing down-sampling while maintaining essential features. This layer’s role in balancing the symmetry of information across the network is vital for optimal performance. However, the choice of pooling method is often based on intuition, which can lead to less accurate or efficient results. This research compares various standard pooling methods (MAX and AVERAGE pooling) on standard datasets (MNIST, CIFAR-10, and CIFAR-100) to determine the most effective approach in preserving detail, performance, and overall computational efficiency while maintaining the symmetry necessary for robust CNN performance.

Equid herpesvirus type 8 (EqHV-8) is known to cause respiratory disease and miscarriage in horses and donkeys, which is a major problem for the equine farming industry. However, there are currently limited vaccines or drugs available to effectively treat EqHV-8 infection. Therefore, it is crucial to develop new antiviral approaches to prevent potential pandemics caused by EqHV-8. This study evaluates the antiviral and antioxidant effects of cepharanthine against EqHV-8 by employing both in vitro assays and in vivo mouse models to assess its therapeutic efficacy. To assess the effectiveness of cepharanthine against EqHV-8, we conducted experiments using NBL-6 and RK-13 cells. Additionally, we developed a mouse model to validate cepharanthine’s effectiveness against EqHV-8. In our in vitro experiments, we assessed the cepharanthine’s ability to inhibit infection caused by EqHV-8 in NBL-6 and RK-13 cells. Our results demonstrated that cepharanthine has a dose-dependent inhibitory effect, indicating that it possesses anti-EqHV-8 properties at the cellular level. Moreover, we investigated the mechanism through which cepharanthine exerts its protective effects. It was observed that cepharanthine effectively reduces the oxidative stress induced by EqHV-8 by activating the AMPK and Nrf2/HO-1 signaling pathways. Furthermore, when administered to EqHV-8 infected mice, cepharanthine significantly improved lung tissue pathology and reduced oxidative stress. The findings presented herein collectively highlight cepharanthine as a promising candidate for combating EqHV-8 infections.

Among crucial factors that control flooding events are extreme climate, urban growth, and mismanagement. Islands in the Nile River have experienced successive cycles of flooding and drying due to recent rainy years in the Nile Basin countries. This paper focuses on the impact of floods on the amounts of ammonium-N released, total concentrations of heavy metals, enzyme activities, and microbial biomass (C and N) in flood soils of 11 Nile River islands. Field moist soils and their airdried counterparts were collected from the outskirts of the island and incubated for 15 days at 30 °C to be analyzed. Results reflected that the amounts of released NH4-N were higher in airdried than in wet soils. The average hydrolysis rates of the studied six enzyme substrates were correlated significantly with organic C, organic N, microbial bio-mass C and N in the field moist soils. The highest correlation coefficients (r) were with rates of hydrolysis of substrates of asparaginase, amidase, and β-glycosaminidase. A significant intercorrelation between rates of hydrolysis of the six studied enzyme substrates and r values which range from 0.81 to 0.98. At 10 mmol kg−1 soil, Co+2, Cd+2, Pb+2, Cu+2, Cr+3, and Ni+2 inhibited the release of NH4-N. Arginine hydrolysis was inhibited by the six heavy metals at 5 mmol kg−1 soil; the most effective inhibitors were Pb+2, Ni+2, and Cr+3. Due to the complex soil enzymatic and organic nitrogen hydrolase activities that occur during floods, fertile fields on the Nile River islands should not be fertilized before the summer flood seasons, which will prevent contamination of the Nile River water and loss of its island soil fertility.

Authors: Xiao Guanhong , Lu Haifeng
Published: November 2024

Geological conditions or human activities will affect the hydrochemical characteristics and formation mechanism of mine groundwater to varying degrees. The northern part of the Beiyi mining area of Gubei Coal Mine is taken as the research area in this study. Based on the data of 52 groups of limestone water (Taihui water) samples in the primary environment, in the mining stage and after grouting, the spatial and temporal variation trend of the chemical characteristics of Taihui water was studied by means of constant index mathematical statistics, a Piper diagram, total ionic salinity, correlation analysis, the ion ratio method and the saturation index. The purpose of this study is to analyze the influence of special geological structures, mining activities and grouting treatment on the formation process of the chemical characteristics of Taihui water, and to provide a basis for the identification of water inrush sources and the resource utilization of deep mine water in this area. The results show that in the three stages, the order of cation concentration is Na+ + K+ > Ca2+ > Mg2+, and the order of anion concentration is changed from Cl− > SO42− > HCO3− to Cl− > HCO3− > SO42−. The hydrochemical type is the most abundant in the mining stage, and tends to be unified after grouting. The dissolution of carbonate minerals, gypsum, rock salt and silicate minerals; cation exchange; pyrite oxidation; and the mixing of grouting precipitation liquid mainly occur in the limestone water. These effects are enhanced or weakened due to the influence of pumping and drainage and grouting precipitation liquid. The results of this study may be beneficial to the sustainable utilization of deep groundwater resources in other similar mines, and promote the establishment of data management and identification mechanisms of water inrush sources in deep coal seams.

Authors: Lemmouchi Zineb , Farhat Mahiddine
Published: November 2024

This study is part of a body of research that seeks to understand an individual's social and cultural identity through their intensive use of social media and membership of virtual communities. It explores the impact of this engagement on their religious, moral and social values. The researcher drew on a variety of specialist references to uncover this social phenomenon. It was found that virtual communities represent a parallel social life to real society, serving as an alternative space. Individuals have begun to replace their real communities with virtual ones, where they find fulfilment of their desires and achievement of their social aspirations, often neglecting their social values. This shift leads to the globalisation of their ideas and beliefs, resulting in the formation of a new identity with unclear characteristics.

Capitalismo pandémico y pandemia de la uberización del trabajo
Authors:   Universidad de Campinas, Brasil, Antunes Ricardo
Published: November 2024

Ubicada en la base de la pirámide social, la clase trabajadora ha sido afectada por la crisis económica y la pandemia del coronavirus (covid-19) a escala mundial. Además de las elevadas tasas de mortalidad, empobrecimiento y miseria, grandes porciones de trabajadores están desempleado y en la informalidad. En este escenario social de devastación, el mundo del trabajo entró en una «segunda ola» de coronavirus: la pandemia de uberización a través de la difusión del trabajo en plataformas digitales operadas por grandes corporaciones globales. Se trata de un fenómeno destructivo de la clase trabajadora y sus derechos en varios sectores de producción, con mayor propagación en los servicios. La situación es desesperante en países del sur, como los casos de India y Brasil, pero también en varios países del norte, aunque con otros menores grados de intensidad. En una fase de profunda crisis estructural, el sistema de metabolismo social del capital encontró una trágica confluencia con la explosión del coronavirus, haciendo más visible al capitalismo pandémico o viral. En este momento tan trágico para la humanidad, ¿la clase trabajadora será capaz de impedir la destrucción en curso y comenzar a demoler el edificio del capital?

Military-medical missions and learning outcomes in health sciences share a structure that facilitates the acquisition of skills in the military medical scenario. The military environment promotes leadership and decision-making under pressure, while in the academic field, learning outcomes guide the development of professional competencies. This essay suggests that clarity in the definition of objectives is crucial in both contexts, suggesting that Bloom and Marzano's Taxonomy can be applied to formulate clear and measurable objectives, promoting a comprehensive development of complex skills. Strategic planning in both areas must be precise and based on a matrix that considers key elements such as the objective, means and context.

Las empresas en Colombia son un componente importante en la dinámica económica de los municipios, y son las cámaras de comercio las encargadas de llevar un registro de su actividad; algunas publican esta información en los anuarios estadísticos para conocimiento general de los interesados, lo que es útil especialmente para la planeación económica.La importancia del sector empresarial en la economía de un municipio radica fundamentalmente en la generación de ingresos, el empleo, la creación de capital, la competitividad local, la creación y el desarrollo de unidades productivas en campos dinámicos que también son relevantes para los gobiernos municipales y grupos de interés.
La experiencia de leer y escribir en la era de las tecnologías intelectuales digitales
Authors:   Universidad Santiago de Cali, Hernández Díaz John Fredy
Published: November 2024

En este texto se aborda el tema de la tecnologización de la experiencia de leer y escribir; el objetivo es emprender una aproximación reflexiva, conducente a establecer la nueva configuración que adquieren la experiencia de escribir y leer con las actuales tecnologías intelectuales digitales y su influencia en el pensamiento abstracto. Ello desde la perspectiva de la filosofía y las neurociencias, particularmente con los aportes de Erik Kandel, Friedrich Nietzsche, Jaron Lanier, Marshall McLuhan, Nicholas Carr, Sigmund Freud y Stanislas Dehaene. En esta reflexión se intenta dejar por sentado que las nuevas tecnologías intelectuales se sirven de la explotación de la debilidad psíquica de los sujetos, para provocar reacciones orgánicas ante los estímulos visuales que emiten y así obtener patrones de conductas o acciones repetitivas adictivas, modalidad empleada por la industria del entretenimiento para sus objetivos económicos. La afectación de estos procesos intelectuales por parte de las tecnologías digitales fomenta un pensamiento instantáneo acorde con la propia lógica de la producción funcional del lenguaje que emplea la tecnología, modificando el tejido neuronal del cerebro, malogrando la lectura sostenida y reflexiva, situando la experiencia de leer y escribir a la sombra. La metodología que se emplea consiste en una selección pertinente de los estudios, basada en una selección lógico-inductiva de fragmentos o citas, los cuales permiten analizar el objeto de estudio.

Background and Objectives: Acute skin wounds present significant challenges, necessitating effective therapeutic strategies. This study investigates the potential of extra­cellular vesicles (EVs) in combination with hydrogel matrices for improving wound healing outcomes.

Materials and Methods: A literature review was conduc­ted following PRISMA guidelines to identify relevant studies. Inclusion criteria comprised prospective in-vivo trials utilizing standardized acute skin wounds on healthy subjects. Key treatments involved topical application of EVs incorporated into hydrogel matrices. Electronic literature searches were conducted in PubMed, Science Direct, and Cochrane Library using specific keywords.

Results: Among 541 initially identified publications, 37 studies met inclusion criteria. After full-text analysis, six studies were included in the review. Findings revealed significant advancements in wound healing outcomes when EVs were combined with hydrogel matrices. These combinations demonstrated accelerated wound closure, enhanced tissue regeneration, and increased collagen deposition compared to controls.

Conclusions: The integration of EVs with hydrogel matri­ces represents a promising approach for improving acute skin wound healing. Synergistic effects observed in the reviewed studies underscore the potential of this com­bination therapy. However, further research is needed to standardize protocols, optimize dosage and delivery mechanisms, and evaluate long-term safety and efficacy. Overall, this study highlights the potential of EVs and hydrogel matrices in addressing the unmet clinical needs associated with novel acute skin wound management.

The disposal of sugarcane bagasse waste, often done through open dumping without further treatment, poses environmental pollution and unpleasant odors. Consequently, the implementation of technology is essential to address this issue, specifically by employing a solid waste recycling technology to produce bio-oil, which holds significant value. Utilizing sugarcane bagasse waste to create bio-oil presents an alternative to minimize aesthetic pollution. This research, sourced from sugarcane bagasse waste obtained from sugarcane beverage vendors in Banyuwangi Regency, explores the conversion of bagasse into bio-oil through the pyrolysis process. Bio-oil is an inorganic compound produced during the pyrolysis process. The aim of this study is to generate bio-oil from underutilized sugarcane bagasse, providing a functional and economically valuable alternative energy source that is both high-quality and environmentally friendly. Additionally, the research aims to determine the concentration and composition of bio-oil resulting from the pyrolysis of sugarcane bagasse. The analysis reveals that the high lignocellulosic content in sugarcane bagasse has the potential to be utilized for bio-oil production.

Perkembangan infrastruktur kota dan pusat industri, serta peningkatan dalam sektor transportasi, menunjukkan pertumbuhan yang pesat. Adanya perubahan dalam kualitas udara disebabkan oleh peningkatan pencemaran udara, yang diakibatkan oleh parameter konsentrasi udara yang melampaui standar baku mutu. Salah satu parameter yang perlu diperhatikan adalah O3. Ozon berfungsi sebagai perlindungan alam terhadap radiasi sinar ultraviolet yang berlebihan. Jika lapisan ozon mengalami kerusakan, hal ini dapat menyebabkan dampak serius seperti kanker kulit pada manusia dan peningkatan suhu global. NOx, yang merupakan salah satu polutan udara, terdiri dari NO dan NO2. NOx banyak berasal dari proses pembakaran, baik dari kendaraan maupun kegiatan industri. Pembentukan NOx juga dapat terjadi pada suhu dan tekanan tinggi, seperti pada mesin kendaraan bermotor atau boiler. NOx memberikan kontribusi pada berbagai masalah lingkungan dan kesehatan. Oleh karena itu, pengelolaan kualitas udara menjadi penting dengan pemasangan sistem pemantauan udara. Studi ini melibatkan penggunaan sistem pemantauan untuk mendapatkan data yang akurat.
