Concrete volume calculation is a crucial factor in preventing cost overruns when preparing the Budget Plan (RAB) for construction projects. In arch bridge projects, the complex structural geometry often makes conventional volume calculation methods complicated and prone to errors, particularly due to the geometric complexity of the arch beams. This study aims to analyze the comparison of concrete volume calculation results between the conventional method and the Building Information Modeling (BIM) method using Autodesk Revit in terms of cost-effectiveness. The case study was conducted on the Short Span II Pulau Balang Bridge Duplication Project in the Nusantara Capital City (IKN), Penajam Paser Utara Regency, East Kalimantan. The research objects include substructures (bore piles, pile caps, abutments, piers, and wing walls) and superstructures in the form of arch beams. The research method employs a quantitative approach by calculating concrete volumes conventionally using AutoCAD and Microsoft Excel, as well as calculating with BIM Autodesk Revit through three-dimensional modeling and Quantity Take-Off (QTO) exports. The results indicate that the BIM Autodesk Revit method generates a larger concrete volume compared to the conventional method, resulting in a higher total cost based on the BIM volume. The total cost for the conventional method amounted to IDR 142,613,245,996.12, while the BIM Autodesk Revit method amounted to IDR 143,127,208,186.60. These differences are influenced by the level of calculation detail, the simplification of shapes in the conventional method, and the precision of modeling in Autodesk Revit.

This research aims to analyze and compare traditional Islamic education systems in Indonesia, Malaysia, and Thailand, focusing on institutional aspects, education systems, learning methods, and curricula. Using a literature study method with a descriptive qualitative approach, this research examines various relevant literature regarding the dynamics of Islamic education in Southeast Asia. The results show that the three countries share fundamental similarities in educational forms, such as pesantren or pondok, which focus on Islamic sciences and moral cultivation. However, significant differences exist in management patterns and the level of integration with government policies. Indonesia maintains a variety of salaf and modern pesantren, Malaysia exhibits a more structured system integrated with the state, while Thailand specifically in the Patani region tends to be adaptive in response to its Muslim minority status. This comparison concludes that the development of traditional Islamic education systems in each country is heavily influenced by the respective social and political contexts.

Python programming has become a fundamental competence in the digital era, yet students often struggle to transform algorithmic logic into functional code. This gap between conceptual understanding and practical implementation skills requires a thorough investigation into learning challenges within the Industrial Informatics Engineering Technology (TRIN) program at Politeknik Manufaktur Bandung. Grounded in Bloom's Revised Taxonomy and Cognitive Load Theory, this descriptive quantitative study utilized a Likert-scale questionnaire and an objective comprehension test administered to 87 third-year students. Data were analyzed using descriptive statistics to map performance across three aspects: conceptual understanding, syntactic comprehension, and implementation ability. Results indicate the conceptual aspect achieved the highest average of 4.15, followed by syntax at 3.56 and implementation at 3.54, with objective test accuracy rates of 76.09%, 65.52%, and 67.36%, respectively. Major obstacles identified include difficulties with looping, debugging, and comparison operators. Therefore, enhanced structured practice and Project-Based Learning approaches are recommended to strengthen students' implementation competencies.

The term "breach of contract" in contract law refers to a breach of promise. Discussions of breach of contract, both in doctrine and jurisprudence, are usually associated with a statement of negligence by the debtor, where the debtor has failed to properly fulfill their contractual obligations, and the debtor is at fault. It must be acknowledged that a breach of contract, or breach of promise, already involves bad faith on the part of the party failing to fulfill their promise. The meaning of "breach of contract" in banking law relates to the occurrence of problem loans at banks, which cause the loan to become non-performing. This is usually due to the debtor or customer not paying by the previously agreed payment date. The existence of a breach of contract is inseparable from the existence of a credit agreement. Whether a debtor is in default cannot be determined simply because there are efforts to rescue loans that have entered a problematic stage. The beginning of a violation of an agreement or default due to someone not being paid, in meeting the credit rescue standards at the bank, usually efforts are made such as Rescheduling, Reconditioning, Restructuring, through this rescue, the debtor is given the opportunity to lose his business, so the concept of default in BW and the Banking Law must be measured through the performance given, in both regulations, then from there the concept of problem credit can be classified. This banking regulation can be said to be a default, the comparison of this concept is the discussion in this thesis.

Rapid population growth in Sidoarjo Regency has triggered massive land-use changes, resulting in increased surface runoff and reduced performance of the drainage system. This study aims to evaluate the hydraulic capacity of drainage channels in the Pondok Sidokare Indah Housing area against design flood discharges with return periods of 2, 5, and 10 years. The method used is a descriptive quantitative approach, involving hydrological analysis using maximum daily rainfall data from 2015–2025 and hydraulic modeling of the existing channel along 350 meters. The frequency analysis results indicate that the Log Pearson Type III distribution is the most suitable method based on statistical parameters and the Smirnov-Kolmogorov goodness-of-fit test. The calculation of design flood discharge using the rational method yields values of 0.749 m³/s (2-year), 1.003 m³/s (5-year), and 1.164 m³/s (10-year). Meanwhile, the maximum capacity of the existing channel ranges only between 0.534 m³/s and 0.733 m³/s. The comparison between hydrological load and channel capacity shows that all observation points (Sta 0+000 to Sta 0+350) are in overflow condition, even for the lowest return period flood discharge. This condition confirms that the current channel dimensions are no longer adequate and require normalization to mitigate annual flooding in the area.

Iron deficiency anemia (IDA) is a condition of insufficient iron that lowers hemoglobin levels and disrupts erythrocyte formation. This condition commonly occurs in children and can weaken the immune system, thereby increasing the risk of recurrent respiratory tract infections such as bronchiolitis, pneumonia, and Acute Respiratory Tract Infections (ARTI). Children with IDA are also at risk of worsening clinical conditions. This study employed a literature review method with a descriptive-analytical approach. A total of 10 journals (2020–2026) from Google Scholar, PubMed, ResearchGate, Elsevier, and the National Center for Biotechnology Information (NCBI) were analyzed using the Population, Intervention, Comparison, Outcome, Study Design (PICOS) framework and synthesized narratively. The results of the review indicate that iron deficiency anemia is significantly associated with an increased risk of recurrent respiratory tract infections in children. Children with IDA have a 2–5 times higher risk of developing bronchiolitis and pneumonia, and up to 10 times greater susceptibility to recurrent ARTI. This condition is also associated with increased disease severity, characterized by low hemoglobin levels, mean corpuscular volume (MCV), and serum iron, as well as elevated total iron-binding capacity (TIBC). Iron supplementation has been proven effective in reducing the incidence of recurrent infections. In conclusion, iron deficiency anemia is associated with an increased risk and severity of recurrent respiratory tract infections in children. Early detection and iron supplementation are essential to reduce morbidity and prevent infection recurrence.

Abstract: Detecting chili leaf diseases remains challenging due to the non-uniform manifestation of symptoms, local discoloration, small lesion regions, and visual similarity between disease patterns and natural leaf background variations. Although YOLO-based detectors provide favorable computational efficiency, lightweight variants often struggle to distinguish subtle lesion characteristics, while conventional attention mechanisms such as CBAM primarily rely on global feature aggregation and may overlook regional activation variability. To address these limitations, this study proposes a YOLOv9s-based detection framework integrated with a Region-Dispersion Channel Spatial Attention (RDCSA) module. The proposed module incorporates regional dispersion statistics, namely mean, standard deviation, and range, as channel descriptors to capture inter-region feature variability before applying spatial attention refinement. Experiments were conducted on the COLD dataset containing 532 original images from five chili leaf condition categories using a split-before-augmentation protocol to ensure objective evaluation. RDCSA was integrated at the P5 feature level and evaluated through attention placement analysis, component-wise ablation, sensitivity analysis, stability assessment, and comparison with modern attention mechanisms. The proposed YOLOv9s + RDCSA model achieved an mAP@50 of 0.894, mAP@50–95 of 0.773, precision of 0.858, recall of 0.861, and an F1-score of 0.859 with only a marginal increase in model parameters. The results suggest that regional dispersion-based attention improves feature discrimination while preserving computational efficiency, particularly for disease symptoms characterized by heterogeneous spatial patterns. Nevertheless, performance remains influenced by visually ambiguous symptom categories, indicating that further validation across multiple datasets and field conditions is required. Overall, the proposed RDCSA module enhances detection capability without substantially increasing computational overhead, making it a promising attention mechanism for lightweight plant disease detection systems.

This study aims to analyze the comparison of financial distress levels measured using the Current Ratio (CR) and the Altman Z-Score model and their relationship with stock returns in PT Charoen Pokphand Indonesia Tbk and PT Japfa Comfeed Indonesia Tbk during the period 2020–2025. The research method used is a quantitative approach with a comparative design, and the sampling technique applied is purposive sampling. Data analysis was conducted using descriptive statistics and multiple linear regression.The results indicate that there is no statistically significant difference between the two companies in terms of hal Likuidity (Current Ratio) dan Financial Distress (Altman Z-Score). Descriptively, CPIN has an average Current Ratio of 1.959 and a Z-Score of 3.700, while JPFA shows slightly lower values but remains within the safe zone. Furthermore, regression results reveal that liquidity and financial distress do not have a significant effect on stock returns. Both companies are classified in the safe zone, indicating a healthy financial condition and low risk of financial distress, while stock returns tend to be volatile and influenced by external factors.The study recommends that companies maintain a balance between liquidity, profitability, and capital structure to sustain financial stability. Investors are advised to consider not only financial ratios but also external factors in decision-making. Future researchers are encouraged to expand the sample size and include additional variables to obtain more comprehensive results.

This study aims to analyze a comparison of coal stockpile volumes using the DJI Mavic 3 Pro Unmanned Aerial Vehicle (UAV) method versus the truck count method at PT. Mitra Barito. Data collection was conducted through aerial photography using a UAV at altitudes of 60 meters and 70 meters, as well as Ground Control Point (GCP) measurements using GPS. The aerial imagery data was processed using photogrammetry software to generate orthophotos and a Digital Elevation Model (DEM), followed by a geometric accuracy test based on the Geospatial Information Agency Regulation No. 6 of 2018, using the Circular Error 90% (CE90) and Linear Error 90% (LE90) parameters. The research results show that high-quality processing at an altitude of 60 meters yields a CE90 value of 2.1619 meters and an LE90 value of 4.3656 meters, thereby meeting the accuracy standards for RBI maps at a scale of 1:5,000, Class 3 for horizontal accuracy, and a scale of 1:10,000, Class 3 for vertical accuracy. Volume calculations of the stockpile using UAVs yielded a result of 22,750.900 m³, while the truck count method produced a volume of 23,503.300 m³. The volume difference between the two methods was 753.400 m³, with a deviation percentage of 3.2%. Based on the research results, the UAV method is considered capable of providing relatively accurate calculations of coal stockpile volume.

The development of the digital economy has driven increased customer interaction through online chat services, making customer satisfaction a key factor in business success. Response speed and chat service quality are two important aspects in shaping the customer experience, but previous research has tended to examine them separately. This study aims to analyze the influence of online chat services and response speed on customer satisfaction partially and simultaneously. The method used is a qualitative approach with a literature review of 12 scientific articles from 2020–2025 obtained from academic databases such as Google Scholar and SINTA. The analysis technique used is descriptive-critical through the identification, comparison, and synthesis of previous research findings. The results show that online chat services have a positive effect on customer satisfaction, primarily through interaction quality such as information accuracy, ease of use, and problem-solving ability. Response speed has also proven to be an important determinant, where a fast response significantly increases customer satisfaction. However, speed without quality has the potential to decrease satisfaction. The discussion shows that the two variables have a complementary and inseparable relationship. Online chat services function as a medium for interaction, while response speed is a quality attribute that determines the effectiveness of the service. Therefore, the integration of both in one model is the main contribution of this research in filling the literature gap, especially in the context of e-commerce in Indonesia.

This study aims to examine the effectiveness of assertive communication techniques in cross-cultural counseling for reducing avoidance behavior among students experiencing interpersonal friendship conflicts. Cultural differences between counselors and clients may influence communication patterns, emotional expression, and conflict resolution processes during counseling sessions. Friendship conflicts among university students commonly arise from jealousy, misunderstanding, social comparison, and ineffective interpersonal communication. These conditions often encourage students to avoid direct interaction to prevent further conflict. This study employed an experimental method using a One Group Pretest-Posttest Design. The participants were students who experienced friendship conflicts and demonstrated avoidance behavior tendencies. Data were collected through counseling individual. The intervention was delivered through counseling sessions that used assertive communication techniques and combined behavioral and humanistic approaches in a cross-cultural counseling setting. The findings revealed that assertive communication techniques were effective in reducing students’ avoidance behavior. After receiving the intervention, participants demonstrated greater confidence in expressing opinions, improved emotional regulation, increased openness in communication, and healthier interpersonal relationships. The study indicates that assertive communication in cross-cultural counseling can serve as an effective counseling strategy to help students manage interpersonal conflicts and improve social adjustment in higher education environments.

This study aims to analyze the use of digital learning media in improving learning outcomes and to examine the impact of social media on adolescents’ behavior in daily life in the digital era. The method used is a qualitative approach with a literature study (library research) design, conducted through the collection, review, and analysis of various relevant scholarly sources. The findings indicate that digital learning media play an important role in enhancing students’ motivation, engagement, and learning outcomes, as they are able to present material in an interactive, engaging, and easily understandable manner. On the other hand, social media has a dual impact on adolescents’ behavior. Its positive effects include ease of communication, access to information, and the development of creativity, while its negative effects include addiction, decreased learning focus, social comparison that lowers self-esteem, exposure to negative content, and the emergence of the Fear of Missing Out (FOMO) phenomenon, which can affect mental health.  Therefore, the wise use of digital media and proper supervision are necessary to support the improvement of educational quality while also fostering positive character development in adolescents.

This Community Service (PKM) activity is motivated by the low capacity of MSME actors and start-up business people in utilizing social media and Artificial Intelligence (AI) technology as a means of digital promotion. These limitations include low digital literacy, limited capabilities for visual content production, weak marketing communication strategies, and inconsistent business social media management. This study aims to improve participants' understanding and skills in optimizing social media and utilizing AI to support business promotion. The approach used is a qualitative descriptive approach, with observation, interviews, documentation, direct practice, discussion, mentoring, and training evaluation. The activity was held in Petukangan, Pesanggrahan District, South Jakarta, with participants consisting of MSME actors, students, and the general public. The results showed that 85% of participants experienced an increase in understanding of digital marketing strategies.In comparison, 78% were able to create promotional content independently with the help of AI, especially through Bing Image Creator and ChatGPT. These findings show that integrating social media and AI can increase creativity, improve content production efficiency, and enhance the visual appeal of MSME promotion. The novelty of this activity lies in integrating AI-based visual design training with strengthening the digital entrepreneurship mindset. Thus, this training model can be an applicable, adaptive, and relevant MSME empowerment strategy for digital economy transformation.

The optimal therapeutic impact of local vaginal drug delivery systems is strongly influenced by the physical characteristics balance of Solid Vaginal Suppositories. A comprehensive review regarding the comparison of mechanical profiles, specifically melting time and crushing strength parameters, from various base classifications constitutes the primary objective of this literature research. The implementation of a Literature Review study design was executed through the extraction of empirical data from twelve experimental journals published within the last ten years. Excessively rapid phase transformation characteristics at physiological basal temperatures and low compression resistance were consistently demonstrated by lipophilic bases such as Oleum Cacao. The risk of structural deformation during the distribution process is highly susceptible to unmodified lipid preparations. High surface elasticity accompanied by a delay in molecular hydration duration reaching 120 minutes was recorded in the utilization of Glycerinated Gelatin Base. Structural rigidity exceeding 4 kgF and disintegration time efficiency under 60 minutes were optimally demonstrated by Polyethylene Glycol (PEG) Base. An enhancement in mechanical resistance against external shocks during the storage period is offered by the thorough modification of the synthetic polymer ratios. Therefore, the determination of the PEG base as the most optimal material is recommended to maintain the quality stability of pharmaceutical products. Compendial regulation standards regarding the physical strength testing of pharmaceutical preparations must be obeyed by every institution to ensure long-term treatment effectiveness. Thus, the alignment between active substance release duration and physical preparation endurance can be realized for absolute patient comfort.

This study aims to analyze the phenomenon of flexing on social media as a representation of social status in digital society through the perspectives of Jean Baudrillard’s simulacra theory and Erving Goffman’s self-presentation theory. The research employs a qualitative method using content analysis of social media posts, particularly on Instagram and TikTok, that display flexing practices. The research data consist of photos and videos containing symbols of luxury, such as branded goods, luxury vehicles, exclusive locations, and consumptive lifestyles. The findings reveal that flexing is not merely an act of showing off, but also a conscious self-representation strategy used to construct a particular social image. The luxury symbols displayed often do not fully reflect reality, but rather represent identity constructions that have been selectively curated and manipulated according to the desired image. From the perspective of simulacra, these representations have replaced reality itself, causing the boundary between reality and representation to become increasingly blurred. Furthermore, the phenomenon of flexing is closely related to consumer culture, the need for social recognition, and personal branding strategies in the digital era. Exposure to flexing content also encourages social comparison, which may lead to psychological pressure among audiences. Therefore, flexing can be understood as a multidimensional phenomenon reflecting changes in how individuals construct identity, perceive reality, and gain social legitimacy within digital society.

This study conducts a systematic review of literature concerning the role of Management Information Systems (MIS) in managing Umrah pilgrim data across Indonesia. Employing a Systematic Literature Review (SLR) guided by the PRISMA protocol, the study examined and synthesized 24 peer-reviewed articles published between 2019 and 2026, drawn from Google Scholar, SINTA, and nationally accredited journal portals. Findings indicate that MIS adoption has yielded notable improvements in operational efficiency, data reliability, service transparency, and the overall quality of managerial decision-making within Umrah travel organizations. Web-based MIS remains the predominant technological approach, offering integrated modules for pilgrim registration, document handling, financial tracking, and departure scheduling. At the national level, government-initiated platforms such as SISKOHAT and SISKOPATUH have demonstrated tangible contributions to the administration of Hajj and Umrah services. Nevertheless, persistent obstacles continue to hinder full-scale adoption, including inadequate digital infrastructure in certain regions, inconsistent internet connectivity, and gaps in human resource competencies for operating digital systems. The study argues that embracing MIS is no longer optional for Umrah travel operators; rather, it constitutes a strategic necessity. Future research is encouraged to investigate long-term implementation outcomes, cross-system comparisons, and data security considerations within the broader digital landscape of pilgrimage service management.

Background: The prevalence of Chronic Energy Deficiency (SEZ) of pregnant women nationally is still 16.9%, and anemia reaches 27.7%, so the development of local food-based Supplementary Feeding (PMT) is needed. Brownies with the substitution of red spinach as a source of iron and purple sweet potato flour as an energy source have the potential to be developed as an alternative to PMT. This study aims to determine the acceptability and nutritional content of red spinach brownies with the addition of purple sweet potato flour as an interlude food for pregnant women. Method: Design using the Complete Random Design (RAL) method. The formulation of making brownies consists of three treatments with a comparison between (red spinach pureee and purple sweet potato flour) as follows: F1 (50:50), F2 (60:40), and F3 (40:60). The acceptance test was conducted using a hedonic test of color, aroma, taste, and texture on 30 semi-trained panelists. Analysis of nutritional content includes moisture content (thermogravimetry), ash content (dry ashing), protein (Kjeldahl), fat (Soxhlet), carbohydrates (by difference), and Fe (Atomic Absorption Spectrophotometry). The data were analyzed using the Kruskal-Wallis test. Research Results: The acceptability test showed that there was no significant difference between the formulations. The F3 formulation with a ratio of 40% red spinach pureee and 60% purple sweet potato flour obtained the highest preference value and was determined as the best formulation. The nutritional content of the F3 formulation includes protein 10.447%, fat 8.047%, carbohydrates 1.5579%, Fe 0.0005%, moisture content 20.68%, and ash content 1.4875%. Conclusion: There was no significant effect of each formulation on the acceptability of Brownis Suggestion: It is hoped that the next researcher can improve product formulation and processing processes to maintain and increase iron (Fe) levels in brownies.

The development of social media has brought significant changes in how individuals perceive themselves, especially among female university students who are in the stage of identity formation. Social media is not only used as a communication tool but also as a space that presents homogeneous beauty standards which can influence self-perception. This study aims to analyze the construction of beauty standards on social media and their impact on female students’ self-perception. The research uses a qualitative approach with a literature review method by analyzing 20  relevant academic articles published between 2020 and 2025. Data analysis was conducted using descriptive qualitative techniques, including data reduction, data presentation, and conclusion drawing. The results show that beauty standards on social media are constructed through repeated visual representations and reinforced by algorithmic systems, creating an idealized image of beauty. This condition encourages female students to engage in social comparison, leading to self-dissatisfaction and decreased self-confidence. However, these effects vary depending on individuals’ ability to filter and interpret information. This study highlights the importance of developing critical awareness in social media use to avoid being influenced by unrealistic beauty standards.

Unemployment remains a serious challenge in Aceh, with an Open Unemployment Rate (OUR) of 8.24% (2025) in Lhokseumawe City and 6.54% (2025) in Banda Aceh City. This study compares the implementation and effectiveness of unemployment alleviation policies in the two cities using Van Meter and Van Horn's policy implementation framework with four effectiveness indicators: training absorption, job placement rate, corporate compliance, and community participation. A descriptive qualitative method with a literature study approach was employed, utilizing secondary data from journals, theses, and official documents. The findings show that Banda Aceh focuses on competency-based training through the Job Training Center (BLK) with certification and third-party partnerships. Lhokseumawe prioritizes Qanun Number 1 of 2020 on local labor priority (minimum 40%). Based on the indicators, Banda Aceh is more effective (55% of graduates employed) compared to Lhokseumawe, where local labor priority implementation is weak due to the absence of sanctions and non-existent coordination with PT. PAG. The novelty of this study lies in its systematic comparison of two Acehnese cities using a policy implementation model that integrates demographic bonus and local context. Specific recommendations: Banda Aceh needs to expand BLK capacity, extend training duration (9–12 months with internships), and mandate graduate absorption reports. Lhokseumawe needs to revise the qanun by adding administrative sanctions, recruit permanent instructors, establish a tripartite supervisory team, and establish an energy-sector BLK in the Arun area in collaboration with PT PAG.

This study aims to analyze the comparison of personal branding strategies implemented by Amry Sophia MUA and Lia Makeup through social media portfolios. The research used a qualitative approach with a comparative case study design. Data were collected through semi-structured interviews, digital observations on Instagram and TikTok accounts, and documentation of both participants’ portfolio content. Data analysis was conducted through verbatim transcription, thematic analysis, and triangulation between interview results and digital observation findings. The results show that Amry Sophia MUA builds personal branding through a consistent visual identity characterized by a modern glam look and Thailand makeup style that appears soft, flawless, and elegant. The target market is more focused on wedding makeup and young adult brides-to-be. Meanwhile, Lia Makeup presents a flawless natural look that is more flexible and suitable for a wider audience. Lia Makeup is also supported by a media team, making the content management more structured and consistent. Both MUAs use Instagram as a visual portfolio platform and TikTok as a medium to show makeup processes, tutorials, and audience interaction. In addition, quick responses, customer testimonials, and authenticity are important factors in building trust and a professional image on social media. Therefore, this study indicates that strong personal branding can be developed through visual consistency, appropriate content strategies, audience segmentation, and effective communication with potential clients.
