The current research, entitled entrepreneurship and innovation and the productive processes developed by students of Industrial Arts at UNE, had the objective of showing the link between the dimensions of entrepreneurship and innovation and the productive processes developed by students of Industrial Arts. In the present study, which is quantitative and used tests related to the descriptive variables previously, we propose the probability that there is a nexus relationship between two variables studied. Regarding the methodology, the applied study was used in a correlative cross-sectional design with an intentional sample of 64 student populations, yielding a result of 28 students. Likewise, a questionnaire was used to collect information, demonstrating the reliability of the Cronbach's alpha coefficient of each instrument (0.826 and 0.814) and its effectiveness by the specialists. We conclude that entrepreneurship and innovation are highly associated with the productive processes developed by Industrial Arts students and are highly positively correlated (p < 0.05 and Spearman rho = 0.655).

El presente estudio titulado Inteligencia emocional y resiliencia de los estudiantes del cuarto ciclo de Educación Primaria de la Universidad Nacional de Educación 2023, tuvo como finalidad determinar la relación que existe entre las variables Inteligencia emocional y Resiliencia. La investigación fue cuantitativa, de tipo básica, diseño no experimental, correlacional transeccional. La muestra fue de 70 participantes, a los cuales se le aplicó el Inventario de Inteligencia emocional de BarOn y el cuestionario de Wagnild y Youngque.Los resultados mostraron la existencia de una relación negativa muy baja (rs= -,149) y no significativa (p=,218; p>,05) entre las variables de estudio, además los niveles de la inteligencia emocional son moderados a diferencia de los niveles de la resiliencia que son altos. Concluyéndose que la variable inteligencia emocional y la variable resiliencia tiene una relación negativa baja en los estudiantes universitarios del cuarto ciclo de educación primaria de la Universidad Nacional de Educación; esto podría indicar que los individuos con mayor inteligencia emocional tienden a necesitar menos resiliencia en términos de recuperación de dificultades, es decir, a medida que aumenta el nivel de inteligencia emocional en los participantes, tiende a disminuir el nivel de resiliencia, o viceversa.

PORTFOLIO OPTIMIZATION UNDER THE MEAN-SEMIVARIANCE BEHAVIORAL HYPOTHESIS. EMPIRICAL EVIDENCE OF THE DEPENDENCE BETWEEN OPTIMAL PORTFOLIO STRUCTURE AND ESG RISK SCORES
Authors:   Lucian Blaga University of Sibiu, Romania, BRĂTIAN Vasile
Published: January 2025

This paper aims to perform a portfolio optimization under the Mean-Semivariance Behavioral Hypothesis and measures whether there is dependence between the optimal portfolio structures thus obtained and ESG Risk Scores. The investigation of such an issue may be justified by the fact that ESG reporting is intended to become a stable evolutionary strategy (in the sense of Smith & Price), and portfolio optimization under such a behavioral hypothesis is in line with behavioral finances, where investors are considered to be twice as sensitive to losses as to gains (in the sense of Kahneman & Tversky). Following such an approach expressed methodologically and empirically, the result we reach, on the data we analyzed, is that: optimal portfolio structures are dependent on ESG Risk Scores and even if this statistical dependence is considered to be of low intensity we observe a pattern. The dependence is in the opposite direction up to the portfolio tangent to the Sharpe Efficient Frontier (the portfolio with the maximum Sortino ratio), after which, the dependence is in the same direction. We also observe other patterns in the analysis.
CHALLENGES AND PERSPECTIVES OF AI IN SUSTAINABLE TOURISM
Authors:   Lucian Blaga University of Sibiu, Romania, CRISTIAN Mihai Gabriel , Tileagă Cosmin ,   Lucian Blaga University of Sibiu, Romania
Published: January 2025

The tourism industry is progressively integrating artificial intelligence (AI) to enhance sustainability and optimize operations. By leveraging big data, AI can provide real-time information, advanced analytics, and decision-making capabilities, supporting tourism stakeholders in implementing sustainable practices. However, the application of AI in this context faces significant challenges, such as issues of governance, ethics, data privacy, and regulatory compliance. In particular, AI’s ability to predict tourism demand and manage energy and waste systems in tourist destinations makes it a valuable tool for sustainable tourism initiatives. Nevertheless, concerns about job displacement and the depersonalization of tourism experiences highlight the need for a balanced approach to AI integration. The future of sustainable tourism will depend on addressing these challenges while fostering innovative AI applications that promote environmental conservation, economic development, and social equity.
THE SUSTAINABILITY REPORTS ISSUED – AN INFLUENTIAL FACTOR FOR THE STOCKS QUOTATIONS?
Authors:   Lucian Blaga University of Sibiu, Romania, MOROȘAN Adrian
Published: January 2025

The integration of sustainability in economics is essential for achieving long-term economic stability and environmental preservation. As climate change, resource depletion, and social inequities intensify, adopting sustainable practices within economic frameworks is crucial. This article delves into the relationship between sustainability and economics, highlighting the impact of non-financial factors, such as sustainability reports, on financial outcomes like stock prices. By analysing the Romanian BET index, we examine the correlation between sustainability practices and market value. Our findings indicate that the visibility of sustainability reports on company websites does not significantly affect stock prices. However, the general upward trend in stock quotations suggests that other factors might play a more substantial role. This study underscores the importance of regulatory frameworks in promoting transparent sustainability practices. Future research will expand this analysis to global markets, aiming to develop a comprehensive company score that incorporates various financial and non-financial factors.
A NEW CONCEPTUAL FRAMEWORK FOR ASSESSING CORPORATE FINANCIAL PERFORMANCE. A SUSTAINABLE APPROACH
Authors:   Lucian Blaga University of Sibiu, Romania, RUSU Radu , OPREAN-STAN Camelia ,   Lucian Blaga University of Sibiu, Romania
Published: January 2025

This study sets out to establish a new definition for the concept of corporate financial performance, mostly associated with the concept of corporate economic growth, highlighting the prevalence of the types of capital such as those specific to natural, human and social. These types of capital comprise resources such as: renewable and non-renewable natural resources (forests, oil deposits), the individual’s health, well-being and knowledge, respectively social relationships based on mutual trust. The method of definition used comprises the sufficiency predicates and implies the development and transformation of four such predicates. Lastly, mathematic relationships are proposed in order to better evaluate the company’s conceptual corporate financial performance, with regard to its consumption of resources specific to those of natural, human and social capital. Nevertheless, the mathematic models imply the existence of some so-called artificial realities, which represent conditions that are not fully reflected in the actual socioeconomic environment.

DIVERGENCE REGARDING ESG. A BIBLIOMETRIC ANALYSIS
Authors:   Lucian Blaga University of Sibiu, Romania, VASIU Diana Elena
Published: January 2025

ESG criteria serve as a cornerstone for sustainable business practices, but the growing emphasis on sustainability has led to a surge in ESG rating providers, introducing significant challenges. ESG ratings are inherently complex and often differ across agencies, due to a lack of standardized parameters, risks of green-washing, and the perceived trade-off between profitability and sustainability. Inconsistent methodologies and fragmented regulatory frameworks hinder meaningful comparisons, resulting in limited confidence among investors and companies regarding the reliability of these ratings. Nevertheless, ESG advocates view these ratings as drivers of long-term financial and societal benefits. Consequently, researchers are increasingly focused on understanding the extent of ESG rating divergence, identifying its underlying causes, evaluating its impact on company performance, and exploring strategies to mitigate the negative effects of these inconsistencies. This paper provides an overview of the topic of “ESG ratings divergence,” a subject that has seen exponential growth in the past three years. Using a bibliometric approach, it examines the academic literature published and indexed in the Scopus database with the help of VOSviewer.

Published: January 2025

This study aims to determine and understand the motivators for sharing on social media. This is why the following research questions delve into these crucial topic areas for content creators and marketers. Why do users share content on social media platforms? If anything, does the nature of content influence sharing on social networking sites? Does the behavior of social media users affect how they share content? We use social media for personal bonding as well, and to ensure that our immediate friend circle appreciates us, we share meme posts only because memes are worth sharing, or just want them to know about something important that happened in the past hour-to-hour. For a project to encourage the spread, it must be of great value/line up perfectly with what motivations will lead them to share that content in their networks. A survey was conducted on Facebook, and data were analyzed using smartPLS(n=300). Various outcomes were driven. The connection between content types and encouraging users to share is strong, resulting in minimal barriers to encouraging sharing. The second subjective norm, the power of social connections, was strongly linked to users’ motivation to share. Across Facebook users, the sharing behavior appears to be dissimilar.

Published: January 2025

The -sh2, bt2, su1, and se- genes in sweet corn cause faster seed deterioration and a lower germination rate. A potential solution to this issue is seed priming. Priming agents and the solution uptake method are key factors that affect the achievement of seed priming. This study aims to compare the influence of solution uptake methods in sweet corn seed priming as well as investigate the effect of KNO3 on the germination and early development of sweet corn plants. The research was conducted in the Seed processing lab of the Department of Agricultural Production, Politeknik Negeri Jember. The seeds used in this study were sweet corn seeds var. Enno 1401. The study was designed with a completely randomized design (CRD). Seven treatments, namely non-primed, KNO3 spraying, KNO3 soaking, KNO3 aeration, RO water spraying, RO water soaking, and RO water aeration, were observed. Data were analyzed using one-way ANOVA, followed by means analysis using Fisher’s LSD (least significant difference) test at P<0.05. The result showed that aeration priming performed better than spraying and soaking in terms of germination percentage, MGT, and GRI of sweet corn seeds. However, aeration priming with KNO3 gave lower results than RO water in terms of MGT and GRI. On the other hand, aeration priming with KNO3 aeration gave the highest result in dry weight.

Published: January 2025

Cookie is a popular and well-liked food but is high in calories and low in fiber. Replacing sugar by artificial sweeteners in cookies is expected to reduce the calorific value of cookies. This study aimed to evaluate the effect of adding artificial sweeteners on the physical, sensory, microbiological characteristics, and functional benefits of cookies. A completely randomized design with sweeteners (stevia and erythritol) and concentrations (0.2%, 0.4%, and 0.5%) was used. The results showed that stevia and erythritol had significantly affected all test parameters, except in the mold/yeast parameters of cookies. The adding of stevia and erythritol significantly decreased L*, a*, b*, hedonic scores, caloric values, dietary fiber contents, total microbial values but significantly increased hardness and antioxidant capacities (IC50) of final cookies. All sensory ratings of the sucrose and formulated cookies were >3 points, which demonstrated that stevia and erythritol can be sugar replacers that can reduce calorie cookies. The findings can guide in the reformulation of low-calorie, high-fiber, and non-gluten cookies.

Published: January 2025

Coconut water kefir is a processed food product, derived from young coconut water. On this product, chemical and sensory properties are maintained through proper post-harvest handling. Therefore, this study aimed to determine the optimal temperature and storage time for coconut water kefir to produce the best sensory properties acceptable to the panelists. The effect of temperature and storage time treatments on chemical parameters was assessed through measurements of pH, °Brix, and alcohol content. Sensory analysis included both hedonic and hedonic quality testing. Furthermore, the experimental treatments applied were variations in storage temperature, both in the freezer (-25℃) and refrigerator (3℃), and storage time of 0, 1, 7, 14, and 21 days. The results showed that the interaction between temperature and storage time had no significant effect on the pH value and °Brix of coconut water kefir. All samples had low alcohol content, with values below 1%. The optimum sensory properties, as perceived by the panelists, were observed in the sample stored at a refrigerated temperature for 1 day. Further statistical analysis using the Kruskall-Wallis Test showed that refrigerator storage had a significant effect on hedonic and hedonic quality testing. Conversely, freezer storage had a significant effect on only the hedonic quality test.

Meanwhile, wild passion fruit (Passiflora foetida L.) interacts with bacteria that have potential to control SBR disease. Therefore, this research aimed to examine potential of endophytic bacteria from wild passion fruit to control SBR disease in pepper plant and the role as growth promoters. A total of 12 endophytic bacteria isolates were tested for potential to promote growth and biocontrol, focusing on the ability to produce the phytohormone IAA, dissolve phosphate, fix nitrogen, as well as produce cellulase and protease enzymes. The three best isolates were then tested on pepper cuttings (Var. Malonan I). The results showed that the highest disease severity was found in control at 40.74% (moderately susceptible), followed by isolate KSA 01 at 37.03%, and SIB 01 at 33.33% (resistant). Disease severity in isolate KPA 03 was significantly lower at 7.41% (very resistant). The highest disease incidence occurred in control and KSA 03 at 44.44%, while the lowest occurred in KPA 03 and SIB 02 at 33.33%. Isolate KPA 03 produced the highest plant height increase (39.87 cm) and the highest number of leaves (5.78), although it was not significantly different from isolate SIB 02. This research showed that endophytic bacteria from wild passion fruit could effectively control SBR disease and improve pepper plant growth.

Patchouli (Pogostemon cablin Benth.) is among the top 20 essential oil-producing plants traded in the global market. This plant shows narrow genetic diversity due to non-flowering and seed production, increasing the challenges in obtaining new varieties through crossbreeding. Therefore, this research aimed to apply mutation method using ultraviolet-C irradiation combined with tissue culture to broaden the genetic diversity of patchouli. The potential of UV-C irradiation and the morphological changes occurring in the plant were explored from October to December 2023 at the Tissue Culture Laboratory, Andalas University, Padang. In addition, the experiment was arranged in a Randomized Complete Block Design (RCBD) with 10 treatment levels and 3 groups. The treatments included UV-C irradiation doses of 0 (wild type), 30, 60, 90, 120, 150, 180, 210, 240, and 270 minutes at a distance of 30 cm. Data for each patchouli plant per observation variable were presented as mean values, variance, and standard deviation and analyzed using an unpaired t-test. The results showed that exposure to ultraviolet-C radiation impacted several morphological characteristics, such as chlorosis, delayed bud development, increased bud and leaf count, as well as faster bud growth. This phenomenon shows the potential of ultraviolet-C radiation as a physical mutagenic agent.

Kombucha is a fermented beverage product often produced by adding kombucha culture into sweetened tea, juices, coffee, and herb extracts. Coffee is a refreshing ingredient commonly served as a beverage prepared from roasted coffee beans. Therefore, this study aimed to investigate the chemical and microbiological characteristics of kombucha beverage produced from robusta and arabica coffee through natural methods with light, medium, and dark roasting profiles. Ground-roasted robusta and arabica coffee were dissolved into a sucrose solution, then the kombucha culture was added to these treatments and fermented for 14 days at ambient temperature. Subsequently, each kombucha beverage was analyzed for Total Soluble Solid (TSS), pH, Total Titrated Acid (TTA), Soluble Vitamin C, Caffeine Content, and Total Lactic Acid Bacteria (LAB). The results showed that TSS decreased on the 14th day due to sucrose degradation by microbes. TTA increased at the end of the processing, followed by a lower pH (2.87–3.49), signifying a safe value for human consumption. The soluble Vitamin C increased on the seventh day and decreased on the 14th day, which was related to the oxidation process during fermentation. The monoanion of ascorbic acid became oxidized by oxygen molecules and formed other unstable compounds. The total LAB and caffeine content elevated along with fermentation time due to the caffeine solubility which increased in low pH solution.

Chemical insecticides are often used to control palm oil pests due to their effectiveness and rapid effects. However, these insecticides leave residues in palm oil, leading to the presence of harmful chemicals that damage the agricultural environment. This has led to the use of various alternatives, such as mechanical control (trap), which is cost-effective and nature-friendly. Therefore, this study aims to determine the potential of trap with different heights and various amounts of pineapple to control horned beetles in palm oil plant. The study procedures were carried out using a factorial random group design and a factorial scheme with 2 treatment factors and 3 repetitions. The first factor was the height of trap mounted with 3 treatments, namely P1 = 100 cm, P2 = 200 cm, and P3 = 250 cm. Meanwhile, the second factor was N1 = 50 grams per trap, N2 = 100 grams per trap, and N3 = 150 grams per trap. Data obtained were then analyzed using Analysis of Variance. When the results differed, analysis was continued with Duncan's Multiple Range Test at the 5% level. The parameters observed were the number of horn beetles trapped, sex ratio, and the species of horn beetles. The results showed that in height treatment, trap had a significant influence on the number of horn beetles over 3 and 9 days. Meanwhile, in pineapple treatment, weight had no significant effect on the number of horn beetles trapped and sex ratio. The results also showed that the interaction between both treatments had no significant impact.

Published: January 2025

Knobweed (Hyptis capitata) is a member of the genus Hyptis and the medicinal properties remain underexplored in scientific research. In this context, the use of Hyptis capitata essential oil as a medicinal plant depends on phytochemical content. Hyptis capitata is easily found in rice fields or agricultural areas such as Banyuwangi. Therefore, this research aimed to describe phytochemical compounds, antioxidants, and antibacterial activity of essential oil Hyptis capitata in Banyuwangi using Solvent-Free Microwave Extraction (SFME) method. Essential oil from leaves and inflorescence of the species was obtained with a yield of 0.273% and 0.282%, respectively. The results of Gas Chromatography-Mass Spectrometry (GC-MS) analysis showed that inflorescence and leaves of Hyptis capitata consisted of diterpenes, triterpenes, sesquiterpenes, esters, alcohols, ketones, and other groups of compounds. SFME method for the extraction affected both essential oil yield and phytochemical composition. Meanwhile, there were variations in phytochemical compounds of the plant parts used and from several previous research. The optimum % DPPH inhibition value of leaves extract and inflorescence were 19.187±0,06% and 18.784±0,06%, respectively. Antibacterial activity against Staphylococcus aureus and Eschericia coli reported no inhibition of plant extract. Phytochemical analysis showed several compounds with antibacterial potential, suggesting the need for further research of antibacterial activity against other pathogenic bacteria and exploration of additional biological activities.

Zoysia matrella is a type of highly valued grass, but the seedling time is very long due to the slow growth rate. Several studies have been conducted using artificial light as a light source to accelerate indoor plant production. However, this technology is yet to be widely used for seed production. Therefore, this study aimed to obtain optimal light intensity from artificial light in accelerating Zoysia matrella seedling time. The treatment in the form of Light Emitting Diode (LED) illumination given to increase the growth of Zoysia seedlings consisted of 5 levels, namely 20, 40, 60, 80, and 100 (μmol/m2/s). The parameters studied were germination percentage, germination rate, and vegetative measurement in the form of seedling height in Zoysia nursery chamber equipped with artificial light. The results showed that the artificial illumination technology in the nursery chamber increased the speed of seedling time in the germination and growth phases of Zoysia seeds.

The objective of the study is to examine the impact of employer branding, person-job fit, and psychological empowerment on turnover intention among Generation Y and Z employees in private banks in Indonesia. This study focuses on analyzing indicators for each variable to describe the characteristics of Generation Y and Generation Z employees. The findings will aid in formulating effective management strategies to reduce turnover intention. This quantitative study employs the Structural Equation Model (SEM) with data collected through online questionnaires from 243 respondents in JABODETABEK areas from May 11 to May 23, 2024. Purposive sampling criteria included Generation Y and Z employees with at least one year of work experience in a private bank and a minimum diploma education. The findings reveal that employer branding, especially regarding compensation and benefits, significantly affects turnover intention, aligning with prior research. Both person-job fit and psychological empowerment negatively impact turnover intention, emphasizing the importance of role alignment and workplace empowerment in reducing employee departures. Generational differences between Generations Y and Z do not significantly moderate these relationships. This research aids organizations in developing effective retention strategies to retain top talent and enhance performance.
