In demographic studies, population growth refers to changes in the number of inhabitants over a given period, measured by calculating numerical differences in population size and expressing them within specific time units to illustrate patterns of increase or decline. Based on data from Tembalang District in Figures 2025, the population growth rate in Kedungmundu Village rose by 0.51% between 2016 and 2025, with most residents relying on clean water services provided by PDAM Tirta Moedal as their primary source of drinking water. This study aims to estimate clean water demand based on projected population growth and to design a pipeline network system capable of meeting future needs. The analysis of water demand applies population projection methods, including arithmetic, geometric, and least square approaches, to compare their levels of accuracy, while the clean water distribution network is modeled using EPANET 2.0. One of the main challenges faced by PDAM is that service coverage has not yet been fully optimized. The ten-year projection results indicate that the arithmetic method provides a correlation value closest to 1, estimating a future population of 14,904 people with a total clean water requirement of 3.48 liters per second. To support this projected demand, the proposed network design utilizes High Density Polyethylene (HDPE) pipes with diameters of 12, 10, and 8 inches to ensure efficient and sustainable water distribution.

The development of bioinformatics has led to the availability of large amounts of genetic data through public databases such as NCBI Gene, OMIM, and Ensembl. However, the complexity of data presentation and the dominance of English language hinder students, novice researchers, and the general public in understanding the relationship between genes and disease. This research aims to develop a simple web-based information system to identify disease-causing genes with concise, Indonesian-language, and user-friendly information presentation. The method used is Research and Development (R&D), which includes literature study, needs analysis, system design, implementation, testing, and evaluation. The system was developed using a MySQL relational database with a web interface that displays basic gene information, chromosome location, biological function, and gene-disease relationships, complete with simple visualizations. Black Box testing results indicate that all main functions run according to user requirements. This system is expected to improve bioinformatics literacy and become an effective learning medium.

This research presents the development of a transaction data protection mechanism for a bouquet sales application by utilizing the Advanced Encryption Standard (AES) algorithm. The rapid growth of digital commerce has led to an increase in online transactions, which in turn raises serious concerns regarding the security of sensitive transaction data. Information such as customer identities, order details, delivery addresses, and payment data are vulnerable to unauthorized access, data leakage, and manipulation if not properly secured. To address these issues, this study applies the AES-128 encryption algorithm using a 128-bit secret key to secure transaction data before it is stored in the system database. The encryption process follows the standard AES workflow, including key expansion, initial transformation, multiple encryption rounds, and a final transformation stage. Decryption is restricted exclusively to authorized users who possess the correct encryption key. The research methodology includes system analysis, AES integration into the application, and functional testing of the encryption and decryption processes. Data integrity is validated by comparing the original plaintext with the decrypted output, while system performance is evaluated based on processing time and decryption accuracy. Experimental results indicate that the average encryption and decryption time remains under 10 milliseconds per transaction, without affecting system performance. The findings confirm that AES-128 effectively enhances transaction data confidentiality and integrity in the bouquet sales application

The development of information technology has significantly improved the efficiency of application-based delivery services, including Shopee Partner Driver couriers. However, several issues such as delays in information updates, system errors, and inaccurate delivery data still affect courier performance. This study aims to analyze the effect of Information Quality and System Quality on the Performance of Shopee Partner Driver Couriers in Medan City. This research used a quantitative method with a questionnaire survey distributed to 100 active couriers. The instrument applied a fivepoint Likert scale, and data were analyzed using validity and reliability tests, descriptive statistics, and multiple linear regression analysis with SPSS software.

This PKM examines the transformation of traditional burial practices in Terusan Village, Ketapang Regency, West Kalimantan, in light of 1 Timothy 6:7. The local community has a tradition of accompanying and placing all the personal belongings of the deceased on the grave as a form of respect and the belief that the deceased's spirit needs these items to prevent them from returning angry. This belief is reinforced by the community's past spiritual experiences, including the testimony of traditional leaders about dreams in which the deceased's spirit asks for their belongings. Using a theological and anthropological approach, this PKM assesses this tradition in relation to the biblical teaching that humans bring nothing into or out of the world. Using theories from theologians and anthropologists, this PKM formulates a dialogical, inculturative, and transformative spiritual development strategy, so that local culture can be guided without experiencing rejection. This PKM concludes that changes in burial practices must be carried out with a pastoral approach that emphasizes the value of spiritual wealth, the hope of resurrection, and an understanding of death in Christ. Thus, local traditions are not erased, but are guided toward new meanings that align with God's Word, leading the community from cultural heritage to genuine spiritual transformation.

The results indicated that both exercises significantly improved athletes’ agility, with shuttle run showing a slightly greater improvement than zig-zag run. These findings reinforce the concept that agility can be enhanced through structured training emphasizing directional changes and speed, and provide practical implications for coaches to integrate shuttle run and zig-zag run exercises in training programs to optimize athletes’ performance.

The 50 meter freestyle is a sprint event that requires explosive strength, efficient technique, and optimal body stability. Arm muscle strength contributes directly to propulsion, while core muscle strength supports stability and force transfer. This study aimed to analyze the influence of arm and abdominal muscle strength on 50-meter freestyle swimming performance among athletes of the Science Swimming Team (SST) Sidoarjo. A quantitative correlational design was employed with a sample of 10 athletes aged 10–12 years (5 males, 5 females). Arm muscle strength was measured using the pull-up test, abdominal strength with a 30-second sit-up test, and swimming performance with the best time in a 50-meter freestyle trial. Data were analyzed using Spearman correlation and multiple linear regression with a 0.05 significance level. Results indicated a significant correlation between arm strength and swimming performance (r = 0.773; p = 0.009), while abdominal strength showed a positive but non-significant correlation (r = 0.609; p = 0.062). Regression analysis revealed that both variables together explained 57.7% of the variance in swimming speed. It is concluded that arm muscle strength has a dominant influence on freestyle sprint performance, whereas core muscles serve as supporting factors for stability and efficiency. These findings highlight the importance of integrated training programs combining arm and core strengthening to optimize sprint performance in young swimmers.

This study addresses the problem of how the implementation of HOTS-based Android gamification influences the higher-order thinking skills of students with ADHD, a group that often faces challenges in traditional learning environments. A quantitative experimental research design was applied, involving 26 students with ADHD from four special needs schools (SLBs) in West Kalimantan. The intervention included HOTS-oriented Android gamified learning, and students' performance was measured using pre-tests and post-tests based on HOTS-level questions. The average pre-test score was 23.72, while the post-test score increased to 53.21. A paired sample t-test showed a significant improvement (t = 8.688 > t_table = 1.708, at a 5% significance level). However, only 57.69% of students met the minimum mastery criteria (KKM = 67), indicating that 15 out of 26 students achieved the expected learning standard. The implementation of HOTS-based Android gamification significantly improved the higher-order thinking skills of students with ADHD. Nonetheless, the overall results, based on average scores and classical completeness, indicate that many students still did not reach the expected level of mastery. Further enhancements in instructional design may be necessary to optimize outcomes for this group of learners.

Rainfall is a crucial factor in the stability of the Earth's ecosystem and has a significant impact on agriculture, forestry, energy, and water management. However, increasingly unstable climate change makes rainfall patterns difficult to predict accurately using traditional methods. The city of Medan, the capital of North Sumatra Province, has a tropical rainforest climate with an average annual rainfall of approximately ±2200 mm and an average temperature of 27°C. Significant weather fluctuations in this area can trigger flooding when rainfall increases and cause water shortages when rainfall decreases (BMKG, 2021). Therefore, a prediction approach that can manage non-linear and dynamic data is needed. Artificial Neural Networks (ANN) are one of the reliable machine learning methods for detecting data patterns. By using the backpropagation algorithm, the model can gradually reduce prediction errors, making it widely used in weather forecasting applications. In this regard, this study uses ANN with the backpropagation method to forecast monthly rainfall in Medan City by utilizing data from 2022–2024 as training and testing data.

Male infertility represents a major global health concern, with oxidative stress playing a central role in the deterioration of sperm quality. In recent years, growing attention has been directed toward herbal medicine as a potential alternative or complementary therapy due to its antioxidant and multi-target properties. However, a comprehensive long-term overview of the global research landscape in this field remains limited. A bibliometric and visualized analysis was conducted using publications indexed in the Scopus database from 2005 to 2025. Eligible peer-reviewed articles were retrieved following PRISMA guidelines. Bibliometric indicators were analyzed using Biblioshiny (R-Bibliometrix) to assess publication trends, leading contributors, and thematic evolution, while VOSviewer was employed to visualize international collaboration networks, co-citation patterns, and keyword co-occurrence clusters. A total of 562 articles were included, revealing a strong upward trend in scientific output, particularly after 2016, with an annual growth rate of 15.78% and a peak in 2025. Iran, China, and Nigeria emerged as the most productive countries, while the Faculty of Veterinary Medicine and several universities in Africa, the Middle East, and Asia were identified as leading institutions. Keyword analysis highlighted three dominant research fronts: semen quality assessment, testicular histopathology, and oxidative stress–related molecular mechanisms. The collaboration network indicated increasing global and South–South research synergy. The field of herbal medicine for male infertility has evolved into a mature and multidisciplinary research domain, increasingly grounded in mechanistic and experimental evidence. These findings provide a strategic overview of research hotspots and emerging trends, offering valuable guidance for future experimental and clinical investigations.

RS at Kemayoran continues to experience low conversion of antenatal care (ANC) patients to delivery services, with a conversion rate of 6.9% in 2024. The maternity ward Bed Occupancy Rate (BOR) also remains below national standards. Preliminary assessments indicate dissatisfaction with the hospital’s healthscape, low mimetic desire reflected in limited recommendations, and suboptimal perceived value. This study examines the effects of healthscape and mimetic desire on childbirth location decisions, with perceived value tested as a mediating variable.Methods: A quantitative cross-sectional study was conducted using Structural Equation Modeling (SEM). Data were collected from 210 ANC patients at RSUD Kemayoran through structured questionnaires. Variables included healthscape, mimetic desire, perceived value, and delivery location decision. All instruments met validity and reliability criteria.Results: Healthscape and mimetic desire significantly influenced the decision to choose RSUD Kemayoran for childbirth. Healthscape did not significantly affect perceived value, whereas mimetic desire showed a significant effect. Perceived value had a significant direct effect on delivery decisions but did not mediate the relationships between healthscape or mimetic desire and delivery choice. Healthscape emerged as the most influential determinant.Conclusion: Physical healthcare environments play a critical role in childbirth location decisions. Improving healthscape quality and strengthening professional and social recommendations may enhance ANC-to-delivery conversion rates in public hospitals.

The implementation of the Health Workload Analysis (ABK Kes) method reveals both strengths and weaknesses, particularly regarding the suboptimal execution of core tasks such as filing and distributing medical records. This study aims to compare the workload of health human resources (SDMK) between primary and advanced healthcare facilities—specifically Banyudono 1 Public Health Center and Indriati Boyolali Hospital—both of which have implemented hybrid medical record systems. Using primary data collected through interviews and observations and analyzed via the ABK Kes method, the results indicate a need for 10 additional staff members in the Casemix Unit at Indriati Boyolali Hospital and 2 additional medical record practitioners at Banyudono 1 Public Health Center. The Available Working Time (WKT) at the Public Health Center was set at 75,000 based on the Minister of PAN-RB Regulation No. 1 of 2020, whereas the Hospital used real-time calculations. While the Public Health Center aligns its policies with Ministry of Health Regulation No. 19 of 2020, the Hospital adjusts its staffing needs based on the ABK Kes results. Given that this method focuses primarily on quantity, future research and development (R&D) should integrate Lean Thinking for process analysis, ABK Kes for capacity, Queueing Theory for dynamic analysis, and NASA-TLX for psychological evaluation to provide a more holistic assessment of staffing needs.
