The emergence of Large-Format Printing (LFP) technology has transformed global visual communication by enabling the production of large-scale, high-quality printed materials, significantly influencing Nigeria’s graphic design industry. This study aims to examine the impact of LFP on graphic design practice (GDP) in 21st-century Nigeria and propose strategies for sustainable development while addressing emerging challenges. A mixed-method approach was employed, with a primary qualitative focus through interviews and participant observation, supported by quantitative data collected using a Likert-scale questionnaire to assess designers’ perceptions of LFP’s influence. The findings reveal a dual impact. On the positive side, LFP has enhanced design scale, print quality, creative flexibility, and production efficiency, effectively overcoming the limitations of earlier methods such as letterpress printing, manual clamp offset printing, and hand-painted signboards. However, several challenges persist, including the oversaturation of practitioners, increased design piracy, and issues of color inconsistency, which undermine quality outcomes. These challenges highlight gaps in professional standards and regulation within the industry. The study concludes that while LFP has driven innovation and growth in Nigeria’s graphic design sector, its optimal benefits are constrained by the proliferation of unaccredited freelance designers. Therefore, the study recommends the implementation of targeted training programs and stricter professional accreditation systems through relevant regulatory bodies to ensure sustainable development and maximize the transformative potential of LFP technology.

Congestive heart failure (CHF) is a cardiovascular disease that frequently causes shortness of breath (dyspnea) and negatively impacts patients’ quality of life. The management of dyspnea involves not only pharmacological approaches but also nonpharmacological interventions, one of which is handheld fan therapy, which works by stimulating sensory receptors in the facial area. This study aims to describe the effect of handheld fan therapy on reducing shortness of breath in patients with CHF. This study employed a descriptive design using a case report method on a single 63-year-old female patient diagnosed with CHF. The intervention was conducted over four days, involving the use of a handheld fan for 10 minutes, held at a distance of 15–30 cm from the face and directed toward the nose and mouth. Measurements were taken before and after the intervention using respiratory rate and oxygen saturation as parameters. The results showed a gradual decrease in respiratory rate from 24 breaths/minute to 18 breaths/minute, as well as an increase in oxygen saturation from 91% to 96% during the intervention period. These findings indicate an improvement in breathing patterns and increased respiratory efficiency in the patient. Handheld fan therapy is effective as a nonpharmacological intervention for reducing shortness of breath and improving oxygenation in patients with CHF. This intervention is safe, easy to use, and can be implemented as a complementary therapy in nursing practice.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in Indonesia's economy but face significant challenges in maintaining consistent and sustainable performance amidst changing market dynamics. This study aims to explore how self-efficacy and entrepreneurial motivation influence MSME performance in Malang City using an exploratory phenomenological qualitative approach. Twelve informants with at least two years of business experience and active operations were selected through purposive sampling. Data were collected through semi-structured interviews, analyzed using an inductive approach, and processed until data saturation was reached. The study found that MSME actors' self-efficacy is shaped by accumulated real experiences, including both successes and failures, which contribute to meaningful learning. Entrepreneurial motivation rooted in personal values was found to be stronger and more enduring than extrinsic motivation. The study identified a cyclical interaction between self-efficacy and motivation, reinforcing each other in fostering adaptive entrepreneurial behavior. Additionally, external factors such as family support, entrepreneurial communities, and government programs play a significant role in sustaining these psychological factors. This research contributes to entrepreneurship literature and offers practical recommendations for stakeholders to design more holistic MSME empowerment programs with tangible impact.

Soil strength characteristics are strongly influenced by its physical and mechanical properties, one of which is shear strength. Soil shear strength is affected by cohesion (c), internal friction angle (ϕ), and soil moisture conditions. In open-pit mining conditions, soil moisture content is greatly influenced by rainfall and water seepage, which can increase the degree of saturation within the soil mass. An increase in the degree of saturation generally leads to a rise in pore water pressure, thereby reducing the effective normal stress and resulting in a decrease in soil shear strength. This study aims to determine the effect of the degree of saturation on soil shear strength. This research employs a quantitative method to analyze the influence of the degree of saturation under three conditions (natural, dry, and saturated) on soil shear strength through laboratory testing using the direct shear test. The tests conducted include soil physical properties testing in accordance with SNI 1965-2008, specific gravity testing based on SNI 1964-2008, and soil shear strength testing following SNI 3420-2016. The results indicate that the average degree of saturation under natural conditions is 64.63% with a cohesion value of 7.4 kN/m², under dry conditions is 33.18% with a cohesion value of 8.2 kN/m², and under saturated conditions is 83.08% with a cohesion value of 3 kN/m². It can be concluded that a higher degree of saturation or more saturated soil samples result in lower cohesion values, whereas a lower degree of saturation or drier soil samples lead to higher cohesion values.

This article proposes Marketing 0.0 as a fundamental conceptual repositioning of marketing theory rooted in the Trust Economy framework. Unlike mainstream marketing theory, which positions trust as an outcome of communication, persuasion, or brand reputation, cross-disciplinary studies in economics, sociology, and neuroscience suggest that trust functions as a pre-decisional condition that precedes market exchange. This research employs a conceptual-theoretical methodology, synthesizing transaction cost theory, social capital, neuroeconomics, and contemporary trust literature. The article's primary contribution is formalizing the shift in trust's position from a dependent variable to an ontological gateway in marketing decision-making. Marketing 0.0 is positioned not as a stage in marketing evolution, but rather as a conceptual ground zero that enables continuous tactical adaptation without reliance on pseudo-novelty. The article concludes with theoretical and practical implications for the development of marketing science in an era of uncertainty and information saturation.

Traffic performance on urban road segments is strongly affected by vehicle volume and travel time, particularly during peak periods. This study analyzes the relationship between travel duration and the total number of vehicles passing along Otto Iskandar Road as an illustration of urban traffic conditions. Data were collected through field surveys, focusing on two main variables: average vehicle travel time and total traffic volume. Statistical analysis was performed using IBM SPSS Statistics, including normality testing and the Wilcoxon Signed Rank Test to identify potential differences between the observed variables. The results show a difference in average values between travel duration and vehicle volume; however, this difference is not statistically significant at the 95% confidence level (p = 0.180). These findings indicate that increases in traffic volume do not always lead to proportional increases in travel time, although they can still influence the stability and efficiency of traffic flow. The results are consistent with previous studies, such as Halim (2021), who reported that U-turn movements affect speed and traffic performance, and Handayani et al. (2024), who found that parking activities and vehicle maneuvers reduce road capacity. Other studies also highlight the impact of side friction and traffic flow variations on speed and saturation levels. Overall, this study emphasizes the importance of managing vehicle flow and monitoring travel time in urban transportation planning and traffic management.

Reservoir heterogeneity has long been recognized as a critical factor influencing the efficiency of enhanced oil recovery (EOR) methods. Among the techniques applied, cyclic waterflooding is considered one of the promising approaches due to its relatively simple operational design and potential to improve sweep efficiency. This method involves alternating water injection in specific cycles to mobilize trapped oil and redistribute reservoir pressure. However, the variation in geological properties such as porosity, permeability, and fluid saturation creates challenges in achieving uniform displacement, especially in reservoirs with high heterogeneity. Understanding the role of heterogeneity is therefore crucial for optimizing cyclic waterflooding applications. This study applies a literature review approach by synthesizing findings from previous experimental and field studies that evaluated cyclic waterflooding under different reservoir conditions. The analysis compares the performance of cyclic water injection periods across reservoirs characterized by varying levels of heterogeneity. Parameters such as injection rate, water breakthrough time, and oil recovery factor were considered in evaluating the effectiveness of this method. The results highlight that reservoirs with high heterogeneity often experience uneven fluid distribution, leading to early water breakthrough and reduced oil recovery. In contrast, reservoirs with relatively low heterogeneity tend to respond better to cyclic waterflooding, resulting in improved sweep efficiency and higher incremental recovery. Moreover, the optimization of cycle timing and water injection intervals appears to significantly mitigate the negative effects of heterogeneity. In conclusion, the study emphasizes that reservoir heterogeneity plays a decisive role in determining the success of cyclic waterflooding. Tailoring injection strategies based on geological variability is essential to maximize recovery efficiency. Future research should focus on integrating advanced reservoir characterization techniques with adaptive cyclic flooding models to further enhance oil production outcomes.

Digital image processing is a rapidly developing branch of computer science and has many applications in everyday life. One of the fields that most often utilizes this technique is object detection and color identification in images and videos. This study specifically aims to implement the thresholding method in the HSV (Hue, Saturation, Value) color space to detect three basic colors, namely red, green, and blue, in digital images. The research process begins with uploading images using the Google Colab platform, a cloud-based computing environment that makes it easy for users to run Python programs without requiring additional software installation. After the image is uploaded, the next step is to convert it from the RGB (Red, Green, Blue) color space to the HSV color space. This conversion is important because the HSV color space is more suitable for use in the color segmentation process. The Hue value represents the type of color, Saturation shows the level of saturation, while Value describes the level of brightness. Once the image is in the HSV color space, the next step is to determine the HSV value range for each basic color. This range is determined based on experimental results and references from related literature. Using this range, masking is performed to extract the appropriate pixels so that only the red, green, or blue portions of the image are visible, while the other colors are reduced. The results show that the thresholding method in the HSV color space is capable of detecting primary colors with a good level of visual accuracy, especially in simple images with contrasting backgrounds. The implementation of this program is relatively lightweight, easy to run directly in Google Colab, and does not require high-spec hardware. Therefore, this method is very suitable for use as basic learning material for digital image processing, both for students and novice researchers.

The rapid increase in Ro-Ro (Roll-On/Roll-Off) vessel and vehicle traffic at Tanjung Perak Port, Surabaya, has exposed critical inefficiencies in port operations, particularly at key berths such as Jamrud Utara and Jamrud Selatan. These inefficiencies manifest as prolonged queuing times for Ro-Ro vessels and land-based vehicle congestion, leading to delays in cargo handling and increased operational costs. This study aims to evaluate the operational performance of Ro-Ro terminals based on queue time indicators for both Ro-Ro vessels and vehicles. Employing a quantitative descriptive approach, the research integrates the M/M/c queuing model and Fishbone Diagram analysis to identify systemic causes of operational delays and overcapacity. The study reveals that berth utilization rates exceed 75%, indicating saturation, while limited buffer zones and disorganized traffic flow exacerbate vehicle queues. As a case study, the findings offer data-driven insights and practical recommendations, including schedule optimization, dedicated traffic lanes, and infrastructural upgrades to mitigate congestion. The proposed framework not only enhances service efficiency at the port but also contributes to broader logistics performance in Eastern Indonesia. By combining classical queuing theory with root cause analysis, this research introduces a methodological synergy that can be replicated across other Ro-Ro terminals facing similar challenges. The findings underscore the urgent need for integrated port traffic management and infrastructural adaptability in response to growing maritime logistics demands.

Unsignalized intersections are a major point of concern due to the increasing number of vehicles. Bima City is a city located on the eastern part of Sumbawa Island, West Nusa Tenggara Province. As a developing city, congestion and busy traffic often occur on roads or intersections of Mongosidi and Anggrek roads. Therefore, this study was conducted to determine the performance and level of service of unsignalized intersections at Mongosidi Street and Anggrek Street. The method used refers to the Indonesian Road Capacity Manual (MKJI) 1997. This study aims to determine the indicators of traffic behavior at unsignalized intersections. The results of the calculation obtained a total flow of 3147 smp / hour, a capacity value (C) of 4234 smp / hour and a degree of saturation (DS) of 0.74, Traffic Delay (DT) of 8.07 sec / smp, intersection delay (D) of 11.73 sec / smp and upper and lower limit queuing opportunities of 44.46% and 17.74% respectively. This condition occurs on Monday, March 17, 2025 at the peak hour of 06.45-07.45 WITA. For the level of service of the intersection pattern, the conditions on Monday, March 17, 2025 at the peak hour of 06.45-07.45 WITA are also categorized as type C, namely stable flow, but the speed and movement of vehicles are controlled.Drivers are limited in choosing speed, with saturation density (Ds) around 0.45 - 0.74.

Employee performance is a measure of organizational progress and development, and is the key to the success of human resource management practices. This study aims to empirically test and prove the mediating role of work engagement on the relationship between meaningfulness of work and ethical climate on employee performance. This study involved the use of Partial Least Square to analyse data collected from 51 employee of Dinas Sosial Kabupaten Gresik. The sampling technique used in this research was saturation sampling method. The results of this study indicate that meaningfulness of work and ethical climate have a significant positive effect on work engagement, meaningfulness of work does not have a significant effect on employee performance, ethical climate and work engagement have a significant positive effect on employee performance. The analysis reveals that work engagement fully mediates the relationship between meaningfulness of work and employee performance, and partially mediates the relationship between ethical climate and employee performance. A good understanding of the meaningfulness of work and a positive ethical climate in the organization encourages work engagement among employees. However, the mismatch between skills and employee job descriptions, lack of employee comfort in working and lack of employee experience in the work they do means that employees cannot provide optimal performance. Ethical climate can also encourage employees to act in the best way at work, meanwhile, work engagement can encourage employee spirit.

Congestive Heart Failure (CHF) is a chronic condition that causes impaired heart function in pumping blood, which can reduce oxygen levels in the body. The increasing incidence of CHF in Indonesia requires appropriate treatment to improve patient health status. One of the evidence-based practice (EBP) interventions that can be applied is the provision of a semi-Fowler position to increase oxygen saturation in CHF patients. This study aims to determine the effectiveness of providing a semi-Fowler position in increasing oxygen saturation in CHF patients undergoing treatment in the inpatient room of Siti Fatimah Hospital, South Sumatra Province. This study uses a qualitative approach with a descriptive case study method on three CHF patients who meet the inclusion and exclusion criteria. Data were collected through interviews, observations, and oxygen saturation measurements using an oximeter before and after the semi-Fowler position intervention for three days. The results showed an increase in oxygen saturation after the application of the semi-Fowler position in all respondents. In Mr. M, there was an increase in average oxygen saturation of 6%, in Mr. N by 3.3%, and in Mrs. N by 4.7%.

Preterm infants have suction and swallowing reflexes that are not well coordinated so that they are prone to aspiration which is characterized by a decrease in oxygen saturation during breastfeeding. Breastfeeding can be given using OGT until the baby has the full ability to switch to Direct Breastfeeding and Cup Feeding. This study used quantitative approach method with quasi experimental research design with two-group pre-test post-test control group design. Data collection was done by direct observation. The research sample amounted to 22 respondents with 11 babies in each group using consecutive sampling. Data were tested using Paired t-test and the test of differences between groups using Unpaired t-test. The results showed a significant effect between direct breastfeeding and cup feeding in premature infants (p value = 0.018; p value = 0.034). And there is no significant difference between breastfeeding through the two methods on oxygen saturation in premature babies (p value = 0.590). In conclusion, this study found that direct breastfeeding is more recommended because it has a higher impact on the oxygen saturation value of preterm infants than cup feeding. Although both have a positive effect on infant oral motor skills in preterm infants

Congestion in Pontianak City significantly impacts traffic flow, affecting both efficiency and comfort of road transit. The city's unsignalized intersections, crucial for managing vehicle flow from multiple directions, are under scrutiny for their performance. A study using the Indonesian Road Capacity Guidelines (IRCG) has assessed intersections, that the degree of saturation often exceeds acceptable limits, leading to congestion and increased delays. The research highlights that the current capacity of these intersections is insufficient to handle the growing traffic demand. For instance, under maximum traffic flow conditions, one intersection recorded a total traffic flow of 2,978.20 pcu/hour against a capacity of 2,716.40 pcu/hour, resulting in a degree of saturation of 1.096. This indicates a need for interventions like installing traffic signals or modifying road geometry to enhance flow efficiency. Despite these findings, the analysis of existing conditions specific unsignalized intersections showed a level of service value of E and F, suggesting that these intersections currently require immediate improvements. However, to further improve intersection performance, recommendations include reducing side obstacles, enhancing road geometry, and installing two-phase traffic signals, which offer the highest capacity with minimal delay. These measures aim to ensure that Pontianak City's transportation infrastructure can effectively.
