Performance Analysis of the 1 MW Rooftop Solar Power Generation System at the Karawang

Electric energy is crucial for development, with Indonesia's projected electricity demand reaching 120 GW by 2025. The National Energy Policy emphasizes the development of renewable energy, particularly Solar Power Plants (PLTS), which have rapidly advanced with increased efficiency and reduced production costs. PLTS has become an attractive option, especially in areas with high solar intensity, for applications such as home lighting and vaccine storage. The target PLTS capacity is 400 MW by 2024. Despite growing popularity, challenges such as high initial costs and efficiency in unstable weather conditions remain. Research shows that environmental factors and shading can affect PLTS performance. This study analyzes the performance of a 1 MW PLTS system at a ceramic factory in Karawang using Global Solar Atlas and PVsyst for simulation and comparison with field data. Simulation results indicate optimal power production >90% with a performance ratio between 81.90% and 84.70%. The built PLTS shows a stable performance ratio above 79%, with power production differing by <10% compared to PVsyst simulation, demonstrating system reliability in actual operational conditions. This research underscores the importance of environmental factors in PLTS design and operation to achieve maximum efficiency.

Analysis of External Environmental Design Factors on Mosquito Breeding in Sikka Regency, East Nusa Tenggara

Factors such as environmental temperature, rainfall, location of waste disposal sites, sunlight exposure, water flow, as well as chemical, biological, and socio-cultural conditions play a crucial role in the development of malaria cases. This study specifically aims to analyze the influence of environmental elements on the number of malaria and dengue fever (DF) cases in Sikka Regency, as well as to evaluate the physical design elements of the area that can reduce DF cases in the region. The research was conducted in several locations within Sikka Regency, taking into account the differences in location and the distance between buildings in relation to thermal characteristics. The results indicate that areas located more than 500 meters above sea level did not experience malaria or DF cases, which is also influenced by the outdoor environmental design, such as building density and vegetation size, affecting light intensity. Lower light intensity increases humidity, which accelerates mosquito breeding.

Form Equals Function: Influence of Coacervate Architecture on Drug Delivery Applications.

Complex coacervates, formed through electrostatic interactions between oppositely charged polymers, present a versatile platform for drug delivery, providing rapid assembly, selective encapsulation, and responsiveness to environmental stimuli. The architecture and properties of coacervates can be tuned by controlling structural and environmental design factors, which significantly impact the stability and delivery efficiency of the drugs. While environmental design factors such as salt, pH, and temperature play a crucial role in coacervate formation, structural design factors such as polymer concentration, polymer structure, mixing ratio, and chain length serve as the core framework that shapes coacervate architecture. These elements modulate the phase behavior and material properties of coacervates, allowing for a highly tunable system. In this review, we primarily analyze how these structural design factors contribute to the formation of diverse coacervate architecture, ranging from bulk coacervates to polyion complex micelles, vesicles, and cross-linked gels, though environmental design factors are considered. We then examine the effectiveness of these architectures in enhancing the delivery and efficacy of drugs across various administration routes, such as noninvasive (e.g., oral and transdermal) and invasive delivery. This review aims to provide foundational insights into the design of advanced drug delivery systems by examining how the origin and chemical structure of polymers influence coacervate architecture, which in turn defines their material properties. We then explore how the architecture can be tailored to optimize drug delivery for specific administration routes. This approach leverages the intrinsic properties derived from the coacervate architecture to enable targeted, controlled, and efficient drug release, ultimately enhancing therapeutic outcomes in precision medicine.

Investigating library users’ perceived indoor environmental quality: SEM-Logit analysis study in a university library

This study aims to identify the key factors that influence library users’ satisfaction with the indoor environmental quality (IEQ) in a contemporary university library, focusing on both perceived IEQ and individual user characteristics. Through a thorough literature review, it pinpoints indoor environment quality (IEQ) and individual users characteristics as critical influences of satisfaction. Data were collected from 404 users within four specific study areas of a selected university library. The study employs structural equation modeling (SEM) and generalized ordered logistic regression (GOLRM), to examine the relationships between perceived IEQ factors and user satisfaction. The SEM showed a good fit and highlighted significant impacts of acoustic quality (coefficient = 0.24, p < 0.01) and interior design (coefficient = 0.65, p < 0.001) on satisfaction. GOLRM analysis revealed that factors such as “age” (odds ratio = 0.810, p = 0.039), “feeling” (odds ratio = 1.420, p = 0.017), and “location (6th floor group-based study area)” (odds ratio = 2.844, p = 0.004) significantly enhance satisfaction, though advancing from medium to higher satisfaction levels poses challenges. These insights suggest that customizing library spaces to meet diverse user needs can markedly improve satisfaction. The study underscores the importance of integrating environmental and personal factors in library design and showcases the effectiveness of SEM and GOLRM in exploring complex interactions within built environments. This approach offers a valuable framework for designers and facility managers to align library spaces with user expectations, making a substantial contribution to the field of built environmental design research.

Toward Healthy Underground Spaces: A Review of Underground Environmental Design Factors and Their Impacts on Users' Physiological and Psychological Health.

This study aims to review and synthesize what design factors are associated with the physiological and psychological health of occupants in underground spaces. The development of underground spaces offers options to global challenges, such as traffic congestion, urban overcrowding, the revitalization of dormant underground areas, disaster mitigation, and adaptation to extreme environments. Despite these advantages, concerns persist about potential adverse effects on human health in these environments. This situation underlines the necessity of systematically identifying concerns and perceptions related to health in underground spaces. A narrative literature review was conducted to examine the relationship between design factors and health factors across 21 empirical studies. Based on the review of the identified literature, a relationship diagram was developed to depict the interconnections between the identified design and health factors. The analysis identified design factors related to the air, sound, light, nature, transport, and spatial context of underground spaces, each of which exerted relationships with occupants' physiological and psychological health factors. The relationship diagram indicated that the psychological factor "feeling of confinement" was mentioned most frequently, suggesting that it is one of the most extensively researched factors in this context. The relationship diagram aims to bridge the existing knowledge gap and set the stage for future research endeavors. The ultimate goal is to refine urban living standards by leveraging the potential of underground spaces while ensuring health and well-being.

Simulations of low impact development designs using the storm water management model

This study assessed the U.S. Environmental Protection Agency's Storm Water Management Model (SWMM) for urban water management challenges. This study conducted a sensitivity analysis to identify the most influential factors in the SWMM. Moreover, the performance of SWMM was evaluated with the HYDRUS-1D module in simulating infiltration rates. The sensitivity results showed field capacity as the most significant factor, highlighting the need for advanced modeling techniques to consider factors like field capacity. The SWMM was evaluated by the HYDRUS-1D that SWMM consistently underestimated peak infiltration rates and commenced infiltration calculations only when soil moisture exceeded field capacity. It reveals its limitations in handling unsaturated soil conditions and highlights the consideration of the matric head of the soil during the infiltration calculation in soil media. Moreover, the evaluation of bioretention areas showed larger areas resulting in more substantial flow reductions but with significant variability under different rainfall conditions. Accordingly, this result emphasizes the importance of careful consideration for environmental factors in bioretention design. This study contributes by enhancing understanding of SWMM's limitations in simulating urban water management challenges. Thus, this research will offer technical assistance to stakeholders focused on challenges such as runoff, hydrologic cycle, and urban flooding in urban areas.

Blue-Green Horizons: Redefining Alginate Bioplastics with Spirulina Dyes

AbstractThis study introduces a novel, eco-friendly approach for the extraction and application of Spirulina (Sp.) pigments in alginate bioplastics, representing a significant advancement over traditional dyeing methods. The research explores a zero waste model process in a Fab Lab setting, involving three stages, liquid dye preparation, fibre dyeing, and bioplastic dyeing, with a focus on utilizing all by-products sustainably. In the liquid dye preparation phase, vibrant blue-green pigments were successfully extracted from Spirulina powder. The colour depth depended on the Spirulina concentration and the precipitation method used, with pH playing a critical role in achieving a range of green–blue hues. The fibre dyeing phase tested Spirulina dyes on various natural fibres, examining the impact of alum mordant pre-treatment on colour absorption and stability. Optimal dyeing results were obtained with a 1:1 ratio of Spirulina-filtered powder suspension to alum acid precipitation solution at a pH of 4. The techniques optimized were then applied to alginate bioplastics, including bio-yarns and bio-films, yielding a wide spectrum from green to blue. Bio-yarns showed better colour retention compared to bio-films, possibly due to residual alum. However, challenges in long-term colour stability and structural integrity against environmental factors like oxidation and humidity were observed. The study contributes valuable insights into the application of natural dyes in bioplastics, particularly in achieving blue and green shades with a Spirulina zero waste model. This work is significant for future sustainable material science research and emphasizes the importance of balancing aesthetic, functional, and environmental factors in circular design.

The impact of light properties on ocular growth and myopia development.

The objective of this article is to comprehensively review the effect of environmental lighting on ocular growth and refractive status in both animal and clinical studies, with an emphasis on the underlying mechanisms. This review was performed by searching research articles and reviews utilizing the terms "myopia," "light therapy," "axial length," "refractive error," and "emmetropization" in PubMed datasets. The review was finalized in December 2023. In the animal studies, high lighting brightness, illumination periods aligning with circadian rhythm, and color contrast signals including multiple wavelengths all help regulate ocular growth against myopia. Long wavelengths have been found to induce myopia in chicks, mice, fish, and guinea pigs, whereas shorter wavelengths lead to hyperopia. In contrast, red light has been observed to have a protective effect against myopia in tree shrews and rhesus monkeys. Apart from wavelength, flicker status also showed inconsistent effects on ocular growth, which could be attributed to differences in ocular refractive status, evolutionary disparities in retinal cone cells across species, and the selection of myopia induction models in experiments. In the clinical studies, current evidence suggests a control effect with red light therapy. Although the lighting conditions diverge from those in animal experiments, further reports are needed to assess the long-term effects. In conclusion, this review encompasses research related to the impact of light exposure on myopia and further explores the retinoscleral signaling pathway in refractive development. The aim is to establish a theoretical foundation for optimizing environmental factors in lighting design to address the epidemic of childhood myopia.

A comprehensive analysis and multi-objective optimization of a sustainable production system based on renewable energies

The adoption and promotion of clean and sustainable energy sources bring about significant benefits to the environment, economy, and society, both in the present and for future generations. This study introduces a pioneering solar-wind biomass multi-generation system, aimed at facilitating the sustainable production of electricity, fresh water, hydrogen, and heating. This system provides a comprehensive evaluation of the influence of environmental conditions and design factors on system efficiency, taking into account the crucial aspects of energy, exergy, economy, and environment (4E). Additionally, a meticulous sensitivity analysis is conducted to identify and prioritize key decision variables that exert the most significant impact on the overall system. Ultimately, the multi-objective optimization is conducted by taking into account various priorities in four distinct scenarios. This approach enables the simultaneous or individual optimization of the system's useful objective functions in relation to the total cost rate. Subsequently, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method is employed to determine the ideal point that best fulfills the optimization criteria. By employing TOPSIS, this study aims to provide a robust and systematic decision-making framework for scenario selection in various domains. By evaluating the optimal points across various scenarios, the first scenario yields the most favorable outcomes in terms of the system's useful outputs. These include an exergy efficiency of 19.63 %, hydrogen production of 11.07 kg/h, fresh water production of 34.16 kg/s, and a total cost rate amounting to 213.80 $/h. Additionally, a considerable decrease of 22.65 % in the total cost rate is noted at the optimal point.

Investigating the impact of extreme environments on the interlaminar performance of nanoparticle-reinforced carbon fiber composites

This study investigates the influence of extreme environmental conditions on the fracture toughness of halloysite nanotube (HNT)-reinforced carbon fiber-reinforced polymer (CFRP) composites. The focus is on the impact of exposure to high humidity and its effects on the mechanical properties of the composites. The study reveals that exposure to high humidity enhances the fracture toughness of HNT-modified CFRP composites, attributed to the entrapped moisture between HNTs and the polymer matrix. This phenomenon enhances crack bridging and contributes to improved mechanical properties. Furthermore, the HNT-modified composites exhibit superior environmental degradation resistance compared to unmodified composites, demonstrating the potential of HNTs as reinforcement for advanced composite materials. The investigation underscores the significance of considering environmental factors in nanoparticle-reinforced composite design and applications, paving the way for the development of durable, high-performance materials capable of withstanding extreme conditions. The findings emphasize the need for continued research to enhance the durability and reliability of such composites, thereby offering sustainable solutions across a range of applications. This study contributes valuable insights towards the design and optimization of fracture-resistant composite materials for demanding environments.

Integrating in situ conservation of plant genetic resources with ex situ conservation management: Involving custodian farmers, benefits and their willingness to accept compensation

Compensation for custodian farmers to provide agrobiodiversity-conservation services in their farms (in situ) is an emerging global approach because it can generate public benefits when it comes to important plant genetic resources (PGRs) for food and agriculture. This review focused on: i) the integration of in situ conservation to the PGR management involving custodian farmers in a systematic conservation approach; ii) the private benefits obtained by custodian farmers to increase their willingness to actively participate in the conservation service; and iii) the willingness to accept (WTA) compensation of the farmers in providing conservation service relative to opportunity costs. The most recent approaches suggest the integration of in situ conservation with ex situ conservation management for efficient conservation programmes, especially in relation to governance of local agrobiodiversity. Involving custodian farmers in the comprehensive genetic-improvement system appears to be an activity that increases their willingness to participate in agrobiodiversity conservation schemes. Farmers receive private benefits, which are simultaneously reflected in the provision of public benefits. Therefore, WTA compensation, which employs mechanisms in the design of payments for better agro-environmental conservation services, controls the opportunity costs. Overall, farmers seem willing to participate in any type of compensation scheme that is proposed in the different countries. Furthermore, it is possible to capture the WTA, therefore significant progress requires more studies of primary schemes, indepth analysis to capture farmers' preferences on economic, socio-cultural, and environmental factors in scheme design, and the implementation of incentive policies designed with pragmatic tools.

USING LIKELIHOOD RATIO TABLE AND NAÏVE BAYES CLASSIFIER METHOD TO HOLISTICALLY ASSESS CODESIGN PROGRAMMES AND METHODS

AbstractThe concept of inclusivity involved an understanding of people, programmes and places, embedded with complex issues. 21 student designers took part in a first-of-its-kind five-day codesign programme to develop solutions for inclusive and engaged communities with residents. This quasi-experimental study aimed to develop a value-based approach using likelihood ratio table and a Naïve Bayes classifier method to assess the success of a codesign programme, in comparison to past programmes with different design challenges. Methodology proposed a systematic investigation to evaluate this programme holistically. Students discussed with stakeholders to uncover the complexities of human and environmental factors in design at early stage of ideation, and semi-structured participants’ observation tasks were considered instead of researcher's observations in the method of assessment. Selected teams were introduced to two new design methods to empathise better with seniors, i.e., Care Circle and See and Shoot. Findings revealed that these teams showed greater levels of critical inquiry when overcoming three key challenges, i.e., (1) identifying key personas, (2) examining potential use environment, and (3) access to market.

An integrated decision-making methodology for green supplier selection based on the improved IVIF-CPT-MABAC method

Green supply chain management attaches great importance to the coordinated development of social economy and ecological environment, and requires enterprises to consider environmental protection factors in product design, packaging, procurement, production, sales, logistics, waste and recycling. Suppliers are the “source” of the entire supply chain, and the choice of green suppliers is the basis of green supply chain management, and their quality will directly affect the environmental performance of enterprises. The green supplier selection is a classical multiple attribute group decision making (MAGDM) problems. Interval-valued intuitionistic fuzzy sets (IVIFSs) are the extension of intuitionistic fuzzy sets (IFSs), and are utilized to depict the complex and changeable circumstance. To better adapt to complex environment, the purpose of this paper is to construct a new method to solve the MAGDM problems for green supplier selection. Taking the fuzzy and uncertain character of the IVIFSs and the psychological preference into consideration, the original MABAC method based on the cumulative prospect theory (CPT) is extended into IVIFSs (IVIF-CPT-MABAC) method for MAGDM issues. Meanwhile, the method to evaluate the attribute weighting vector is calculated by CRITIC method. Finally, a numerical example for green supplier selection has been given and some comparisons is used to illustrate advantages of IVIF-CPT-MABAC method and some comparison analysis and sensitivity analysis are applied to prove this new method’s effectiveness and stability.

Evaluation of Multisensory Interactions Between the Healing Built Environment and Nurses in Healthcare Nursing Stations: Case Study of Tehran Hospitals.

Nursing stations are important features of medical centers that are constantly in use. As nursing is an inherently stressful occupation, nursing stations should be designed to minimize stress on those who must spend time there. This study evaluated the effect of environmental design factors on mitigating the stress levels on nurses in nursing stations by determining the environmental factors that most influence the perceptual senses that affect physical and psychological comfort. A quantitative approach was used to evaluate the parameters that affect the sensory perceptions of nurses in nursing stations at four hospitals in Tehran. A survey was conducted to identify environmental design parameters that affect the visual, auditory, tactile, kinesthetic, and olfactory senses. The results revealed that the olfactory category scored highest, followed by the auditory, visual and tactile categories, which had similar scores, and kinesthetic was ranked last. A connection was revealed between the educational level of the nurses and environmental factors affecting their sensory perception in terms of materials, aesthetics and the appropriate number of windows as a visual sense, and ergonomics as a kinesthetic sense. Significantly, the gender variable differed in the Furniture variable based on comfort of seating with respect structure. Based on the results of this study, a combination of olfactory, visual, and auditory factors should be required at the nursing stations to decrease the stress level of nurses.

Enhanced Pavement Design and Analysis Framework to Improve the Resiliency of Flexible Airfield Pavements

Changes in climatic conditions can directly affect pavement performance. However, accounting for environmental factors in airport pavement design remains a challenge since design methods such as FAA rigid and flexible iterative elastic layered design (FAARFIELD) do not consider moisture and temperature variation as input. Therefore, to address this research gap and improve the resilience of airport pavements, this research proposes a new methodology for the structural design of flexible airport pavements. The proposed methodology in this research was applied to a case study of an international airport in Canada, using actual field data. Five scenarios were evaluated including the current climate, temperature increase, lower matric suction, and two flooding events. The results of the proposed design method showed that the traditional FAARFIELD analysis can possibly overestimate fatigue damage, and underestimate rutting damage. The outcomes showed that climate change can increase pavement damage and shorten the service life from 7 to 14 years in the scenarios evaluated. It was also concluded that the lowering of the matric suction can result in the highest damage levels. Considering the implications of climate change on transportation infrastructure, the proposed methodology can contribute to designing more resilient airport pavements in the future, since it accounts for climate variations, temperature, and moisture changes, as well as extreme events such as flooding over the design life of flexible airport pavements.

How the Built Environment Moderates Gender Gap in Active Commuting to Schools.

This study investigates the influences of built environmental (BE) factors, network design, and sociodemographic factors on active school travel (AST). Although numerous studies have explored these relationships, this study is trying to assess this issue with a focus on gender differences. Data from a cross-sectional sample of children from first to sixth grades from 16 public primary schools exclusive for girls and boys (N = 1260) in Shiraz collected in November 2019 was used. The analysis of the data revealed that, on average, boys are more willing to walk than girls, but that the boys' tendency to walk is less elastic with respect to distance. Moreover, it is shown that street connectivity for all distance thresholds has a positive relationship with walking level, but the street network choice parameter decreases the chance of walking within an 800 metre threshold. It is demonstrated the need to take gender differences into account in local planning policies to promote AST in a developing country context.

Comprehensive modeling and parametric analysis of Multi-Mission Radioisotope Thermoelectric Generator

Radioisotope thermoelectric generators (RTGs) have been widely used as a promising power source for space mission, in which the Multi-Mission RTG (MMRTG) is the state of the art type. However, due to the scarcity of the 238 P u fuel and associated cost concerns, there exists an imperative need to increase the efficiency of RTGs. This requires intuitive, detailed and accurate system property predictions of the RTG system. In this work, a comprehensive finite element model of the MMRTG has been developed, by using a commercial software, COMSOL Multiphysics, including a full-size three-dimensional geometry model, temperature dependent materials and the thermoelectric and radiation heat transfer multiphysics fields involved. The calculation results agree well with reported experimental and simulated values. Through the obtained detailed temperature and voltage distribution, thermal and power properties of the MMRTG are characterized and the effects of non-uniform distributions of temperature and power generated in each TE couple are revealed. At last, the parametric analyses of operation conditions, thermal environment and key design factors are performed and several salient findings have been obtained. Through the analysis results, the design parameters and working mechanisms of the MMRTG are clarified, which can help the design and optimization of the future hundred-watt RTG. • The comprehensive FEM method is first implemented in the MMRTG modeling and analysis. • The non-uniform distributions of temperature and power in TE modules are revealed. • Suitable load and sufficient thermal inventory ensure adequate power output. • The insensitivity of performance to ambient temperature expands MMRTG’s application.

EEG-based spatial elements optimisation design method

In the field of digital design, a recent hot topic is the study of the interaction between spatial environment design and human factors. Electroencephalogram (EEG) and eye tracking can be used as quantitative analysis methods for architectural space evaluation; however, conclusions from existing studies on improving the quality of spatial environments based on human factors tend to remain qualitative. In order to realise the quantitative optimisation design of spatial elements from human physiological data, this research used the digital space optimisation method and perceptual evaluation research. In this way, it established an optimisation method for built space elements in real-time using human psychological indicators. Firstly, this method used the specific indicators of the Meditation value and Attention value in the human EEG signal, taking the ThinkGear AM (TGAM) module as the optimisation objective, the architectural space colour and the window size as the optimisation object, and the multi-objective genetic algorithm as the optimisation tool. Secondly, this research combined virtual reality scenarios and parametric linkage models to realise this optimisation method to establish a tool platform and workflow. Thirdly, this study took the optimisation of a typical living space as an example and recruited 50 volunteers to participate in an optimisation experiment. The results indicated that with the iterative optimisation of the multi-objective genetic algorithm, the specific EEG index decreases significantly and the standard deviation of the in-dex fluctuates and decreases during the iterative process, which further indicates that the optimisation method established in this study with the specific EEG index as the optimisation objective is effective and feasible. In addition, this study laid the foundation for more EEG indicators and more complex spatial element opti-misation research in the future.

The Role of Healthcare Facility Design on the Mental Health of Healthcare Professionals: A Literature Review.

This study aims to review and synthesize the empirical evidence about the connection between healthcare facility design and the mental health of healthcare professionals by reviewing the relevant literature. Mental exhaustion of healthcare professionals is becoming a critical issue in healthcare, especially during the pandemic. The physical design of healthcare facilities has significant potential to reduce and prevent the mental exhaustion of healthcare professionals by removing environmental stressors and providing restorative experiences. However, the built environment is not fully utilized as an intervention to support healthcare professionals. Relevant articles were identified from the Medline, PsycINFO, PubMed, and Web of Science databases using a combination of search terms representing environmental design factors and health outcomes. Identified articles were reviewed by their titles, abstracts, and full texts using the inclusion and exclusion criteria. The search yielded 27 empirical articles investigating the relationships between environmental design factors and staff mental health outcomes, including stress, fatigue, job satisfaction, burnout, and well-being. Healthcare design aspects that were investigated in the identified articles include overall facility and perception (e.g., aesthetic appeal and impression, belonging to the surroundings, safety), specific spaces (e.g., patient area, staff workspace), intangible elements (e.g., exterior view, light, sound), and interior space and ergonomics (e.g., material finishes, furniture). Through the synthesis of the current literature regarding the relationships between healthcare facility design and the mental health of healthcare professionals, this study provides implications for supporting healthcare professionals through the design of the healthcare facility.
