Background: Adolescence is often characterized as a period of puberty. Early menarche is associated with increased mortality and morbidity risks in later life among girls who experience menarche at an early age. Menarche is the first menstrual event in girls, marked by the shedding of the uterine lining and vaginal bleeding. The tendency to consume unhealthy foods, particularly fast food, as well as sugar-sweetened beverages (SSBs), may have adverse effects on health and potentially influence the timing of menarche. Objective: This study aimed to analyze the relationship between healthy food selection, sugar-sweetened beverage consumption, and the incidence of early menarche. Methods: This study employed a cross-sectional design. The sample consisted of 30 female students. Data were analyzed using the Spearman Rank correlation test. Results: The results showed that healthy food selection was significantly associated with the incidence of early menarche (p = 0.005) with a moderate correlation strength (ρ = 0.449). Similarly, sugar-sweetened beverage consumption was significantly associated with the incidence of menarche (p = 0.000) and demonstrated a very strong correlation (ρ = 0.841). Conclusion: There was a significant relationship between healthy food selection and sugar-sweetened beverage consumption with the incidence of menarche. Sugar-sweetened beverage consumption showed a stronger relationship with menarche incidence compared to healthy food selection.

The shift in the structure of modern society's economy from an agrarian base to a service- and expertise-based one has given rise to new forms of income, namely salaries, wages, and professional honorariums, which are not explicitly regulated in classical zakat fiqh. This phenomenon has generated the discourse on professional zakat (zakat profesi) as one of the central issues in contemporary fiqh muamalah. This article aims to analyze the legal basis, the methods for determining nisab and haul, and the map of scholarly disagreement (ikhtilaf) regarding professional zakat, while also examining its relevance to the objective of social justice in Islam. This study employs a qualitative method with a normative-juridical approach through library research, examining the Qur'an, hadith, legal maxims (qawa'id fiqhiyyah), fatwas of religious institutions, and journal articles published within the last five years. The findings show that the majority of contemporary scholars, including Yusuf al-Qardhawi, obligate professional zakat based on the general implication of zakat verses and the method of analogical reasoning (qiyas), likening it to the zakat on gold and silver in terms of nisab (equivalent to 85 grams of gold, at a rate of 2.5%) or to agricultural zakat in terms of the timing of payment. However, some scholars, particularly those adhering to the principle of tauqifiyyah in worship, reject the obligation of professional zakat as a distinct category because it lacks explicit textual basis. This disagreement reflects the methodological tension between textual and contextual approaches in legal reasoning (istinbath al-ahkam), while also demonstrating the flexibility of Islamic fiqh in responding to socio-economic dynamics without abandoning the fundamental principles of sharia. Keywords: Professional Zakat, Contemporary Fiqh, Qiyas, Nisab And Haul, Scholarly Disagreement.

The gap between state financial losses adjudicated and assets actually recovered in corruption cases is commonly attributed to institutional weaknesses or the absence of an Asset Forfeiture Act, while the temporal dimension of seizure is rarely examined. This article argues that the timing of seizure is the key operational determinant of state financial loss recovery. Two research questions are addressed: the normative construction of seizure across the stages of investigation, prosecution, and execution, and how seizure timing affects recovery effectiveness when analysed through Economic Analysis of Law, together with a reconstruction of relevant provisions. Using a juridical-normative method, the research combines comparative approaches, with Jiwasraya as the primary case study and Asabri, alongside comparisons with Singapore, South Korea, and Italy. The analysis identifies the investigation stage as the golden time for seizure because it offers the opportunity to preserve and recover assets, whereas the execution stage yields the lowest marginal benefit. The widening asset recovery gap between these stages can be interpreted as a social cost that may be reduced without changing the prevailing conviction-based system. Furthermore, the 2025 Criminal Procedure Code, the institutional consolidation of the Asset Recovery Agency, and Attorney General Guideline No. 7 of 2025 strengthen the role of the Public Prosecution Service as dominus litis in the asset recovery cycle. Five reconstruction proposals are formulated, most of which can be implemented within the existing legal framework.

The acceptance sampling test of coffee cherries is an important quality control stage in Arabica coffee processing, yet operational evidence at the estate level remains limited. This study aimed to analyze the implementation of acceptance sampling for coffee cherries and to identify the proportions of normal and defective cherries as a basis for improving harvest quality. The research was conducted at an Arabica coffee estate in Situbondo by observing monthly harvest samples from April to August 2024 to classify cherry color (red, partially ripe, green, and black) and fruit density after soaking (partially empty, empty, single bean, and double bean). The results showed that the cherry composition consisted of 93.63% red, 3.54% partially ripe, 0.09% green, and 2.84% black cherries. The density test results indicated 4.30% partially empty cherries, 0.79% empty cherries, 10.27% single-bean cherries, 84.58% double-bean cherries, and 4.00% coffee berry borer-infested cherries. These findings indicate that acceptance sampling is useful for identifying harvest lots that do not meet quality standards and can serve as a basis for improving red cherry picking practices, harvest timing, and field supervision.

This study aims to analyze the effectiveness of the e-SIDAK application as a tool for recording and evaluating the performance of civil servants at BKPSDM Belitung Regency. The research employs a descriptive qualitative approach with 12 purposively selected informants, including managers, administrators, and application users. Data were collected through semi-structured interviews, observations, and documentation, and analyzed thematically using NVivo 12 Pro based on the digital service effectiveness indicators proposed by Pedrosa et al., namely ease of use, simplicity, understandability, consistency, trustworthiness, availability, speed, and usefulness. The findings indicate that the e-SIDAK application fulfills most effectiveness indicators, particularly in terms of ease of use, process simplicity, clarity of information, interface consistency, and service usefulness. The application facilitates systematic work activity recording, simplifies reporting, improves employee discipline, and supports performance monitoring integrated with the employee performance allowance system. However, its effectiveness remains limited in terms of system reliability, service availability, and access speed due to server capacity constraints, network conditions, and the accumulation of data input at the end of reporting periods. In addition, the point-based evaluation system has not fully reflected task duration, complexity, and workload. This study recommends strengthening system infrastructure, developing user guidelines, regulating input timing, and improving the point-based evaluation system to enhance digital service effectiveness in local government institutions.

Population growth and socio-economic activities increase traffic volume, affecting the performance of the Raden Kusno – A. Djaelani – Sujarwo signalized intersection. This study aims to analyze the intersection’s current performance, estimate its condition over the next five years, and formulate alternative treatment strategies. The research data include geometric characteristics, signal timing, vehicle speed, and traffic volume obtained from CCTV recording over a three-day observation period from moning to evening, as well as population and vehicle data for projection. The intersection performance was analyzed using the PKJI 2023 approach and VISSIM simulation. Under current conditions, the intersection operates at LOS E with delays of 45,12 seconds (PKJI 2023) dan 60,56 seconds (VISSIM). In the five-year projection, delays increase to 48,97 seconds with LOS E (PKJI 2023) and 131,29 seconds with LOS F (VISSIM). Modifying the signal from four to three phases with a 70-second cycle improves the current condition to LOS C, with delays of 24,50 seconds (PKJI 2023) and 29,43 seconds (VISSIM). For the five-year projection, adding a continuous left-turn lane results in LOS D with 27,04 seconds (PKJI 2023) and LOS C with 32,01 seconds (VISSIM).

This study investigates the use of oral corrective feedback (OCF) in English as a Foreign Language (EFL) classrooms among Indonesian university students, with a particular focus on lecturers’ preferences and students’ perceptions. The research addresses three main aspects: the types of errors that are corrected, the strategies of OCF employed, and the timing of feedback delivery. A qualitative case study design was adopted, involving classroom observations, semi-structured interviews with lecturers, and open-ended questionnaires distributed to students. Data from these instruments were analyzed separately and then triangulated to ensure credibility and validity. The findings reveal that lecturers mainly prioritize correcting phonological and grammatical errors, as these are perceived to directly influence students’ communicative competence and overall speaking performance. Among the six OCF types proposed by Lyster and Ranta (1997), recast and repetition emerged as the most frequently used strategies. These approaches were favored by lecturers as they corrected learners subtly while minimizing the risk of embarrassment and maintaining the flow of communication. Furthermore, lecturers applied both immediate and delayed feedback depending on the classroom context and learning objectives. From the students’ perspective, OCF was generally viewed positively, as it contributed to raising awareness of errors and fostering speaking improvement. Students particularly appreciated feedback strategies that respected their confidence and speaking flow. Overall, the study underscores the importance of aligning teacher practices with student preferences to maximize the effectiveness of oral corrective feedback in EFL learning contexts.

This study aims to comprehensively examine the concept of intention and the recitation of Surah Al-Fatihah in prayer from the perspective of the four imams of the schools of jurisprudence: Hanafi, Maliki, Shafi’i, and Hanbali. The background of this study is based on the existence of differing opinions among scholars, which often cause confusion among the public regarding the correct practice of prayer. The method used is qualitative research in the form of a literature review (library research), through data collection from classical fiqh texts, scientific journals, and other relevant literature. The data analysis technique employs a descriptive-comparative approach to identify the similarities and differences in the views of each school of thought. The results of the study indicate that all schools of thought agree that intention is an act of the heart that constitutes a valid condition for prayer, yet they differ regarding the timing of its performance and its verbalization. Regarding the recitation of Surah Al-Fatihah, the Shafi’i school mandates it as a pillar in every rak’ah, whereas the Hanafi school does not consider it a pillar. The Maliki and Hanbali schools adopt a moderate stance by granting leniency under certain conditions. These differences reflect the richness of Islamic jurisprudence, which is dynamic and flexible. This study is expected to provide a more comprehensive understanding and foster an attitude of tolerance in addressing differences in worship practices.

Medication adherence among the elderly is an important factor in achieving successful therapy, particularly during the month of Ramadan when changes occur in meal patterns and medication schedules. Elderly patients with chronic diseases often experience difficulties in adjusting their medication timing, which may lead to poor adherence. This study aimed to implement a smart pill boxwith educational labels to improve knowledge and medication adherence among elderly individuals during fasting. The study involved 40 elderly respondents in a social care institution. The intervention consisted of training on the use of the smart pill box, educational labeling, and evaluation through observation, interviews, and checklist forms. The results showed that most respondents took medication twice daily (42.5%) and adjusted their medication schedules to sahur and iftar (45%). Before the intervention, 57.5% of respondents had not received information about medication use during fasting. The implementation of the smart pill boxwith educational labels improved the elderly’s understanding of medication use and supported better medication adherence during Ramadan.

The rapid development of digital technology has led to an increased adoption of digital payment methods in online transaction-based businesses. However, in practice, failures and limitations in the implementation of digital payment systems still occur, potentially disrupting transaction processes and reducing customer convenience. Payment related obstacles may result in transaction cancellations and increase the risk of customer churn. This study aims to analyze the impact of failures and limitations in digital payment methods on customer churn using a classification-based approach. The data used in this research are secondary e-commerce customer data obtained from the Kaggle platform, including transaction information, payment methods, customer behavior, and historical transaction records. The research methodology consists of data preprocessing, time-based feature engineering, and classification modeling using logistic regression, decision tree, and random forest algorithms. Model performance is evaluated using accuracy, precision, recall, F1-score, and confusion matrix metrics. The results indicate that the decision tree model demonstrates superior capability in identifying churn customers compared to the other models, although it does not always achieve the highest accuracy. In addition to digital payment methods, other factors such as purchase value, transaction frequency, purchase timing patterns, and product return rates also influence customer churn. The findings highlight the importance of optimizing digital payment systems as part of customer experience enhancement strategies and customer retention efforts in online transaction–based businesses.

The rapid growth of e-commerce has intensified the need to understand transaction patterns and customer purchasing behavior as a foundation for strategic decision-making. This study aims to analyze e-commerce transaction patterns and customer purchasing behavior based on demographic characteristics and transaction timing. By utilizing e-commerce transaction data, this research seeks to provide a more comprehensive understanding of customers’ purchasing tendencies and the factors influencing their behavior. This study employs Exploratory Data Analysis (EDA) as the primary method to descriptively explore data characteristics through various statistical visualizations, including histograms, bar charts, line graphs, and boxplots. The analysis conducted to identify transaction trends, the distribution of purchase values, and behavioral differences across demographic groups and specific time periods. The results indicate that e-commerce transaction patterns tend to increase during certain periods, particularly in the latter part of the observation timeframe, suggesting the influence of seasonal factors and promotional strategies. The distribution of transaction values is asymmetric, with most transactions occurring in the low to medium value range, while high-value transactions are conducted by a relatively small proportion of customers. Furthermore, variations in purchasing behavior are observed across demographic groups in terms of transaction frequency and value, despite relatively balanced transaction volumes. The findings confirm that e-commerce customer purchasing behavior is influenced by a combination of temporal factors and demographic characteristics. These results are expected to serve as a basis for e-commerce practitioners in developing more targeted marketing strategies and as a reference for future research in the field of e-commerce data analytics.

Oral and dental health problems among elementary school children remain relatively high, particularly dental caries, which is influenced by low levels of knowledge and inadequate toothbrushing skills. Children aged 6–12 years are in the mixed dentition phase and therefore require special attention in maintaining oral hygiene. This community service activity aimed to improve the knowledge and toothbrushing skills of elementary school students through a demonstration method using a dental phantom model. The activity was conducted at SD Inpres Maccini Sombala I in January 2026 and involved elementary school students as participants. The methods applied included oral health education, demonstration of proper toothbrushing techniques using a dental phantom, mass toothbrushing practice, and evaluation through pre-test and post-test as well as direct observation. The results showed an improvement in students’ understanding of the correct timing, frequency, and technique of toothbrushing, namely brushing twice a day after breakfast and before bedtime. In addition, students were able to practice proper toothbrushing techniques more effectively after the demonstration. The use of a dental phantom as an educational medium proved to be effective in increasing students’ interest, understanding, and toothbrushing skills. This activity is expected to help establish good toothbrushing habits from an early age and support promotive and preventive efforts to reduce the prevalence of dental caries among elementary school children.

Postoperative pain is a common clinical condition experienced by patients after surgical procedures and may hinder the recovery process if not properly managed. In addition to pharmacological therapy, safe and effective non-pharmacological interventions are needed, one of which is early mobilization. This study aimed to analyze the effect of early mobilization on pain reduction in postoperative surgical patients. A scoping review method was conducted based on the Arksey and O’Malley framework. Literature searches were performed using ScienceDirect, PubMed, and Google Scholar databases with a PICO strategy, including articles published within the last five years. From a total of 167,948 identified articles, 10 studies met the inclusion criteria and were included in the analysis. The results showed that early mobilization performed gradually and according to patients’ clinical conditions had a significant effect on reducing postoperative pain intensity. In addition, early mobilization was associated with improved comfort, enhanced functional recovery, and faster postoperative rehabilitation without increasing the risk of complications. Although variations were found in the timing and type of mobilization across studies, overall evidence supports that early mobilization is safe and effective. In conclusion, early mobilization can be recommended as an evidence-based nursing intervention for postoperative pain management.

Chronic liver disease is a significant health problem and places a significant burden on healthcare services. Deaths from complications of chronic liver disease (cirrhosis and cancer) account for approximately 3.5% of all deaths worldwide each year. Hepatocellular carcinoma (HCC) is a primary liver tumor, accounting for 90% of all liver tumors. Due to limitations in liver transplantation, liver resection is considered the treatment of choice for HCC patients with a single tumor and sufficient liver function reserve. Liver resection and transplantation are the only curative treatment options available for HCC patients. Surgical procedures require anesthesia. General anesthesia is the preferred method for liver tumor resection. There are five main classes of anesthetic agents: intravenous (IV) anesthetics, inhalational anesthetics, IV sedatives, synthetic opioids, and neuromuscular blocking agents. Estimated health risks depend on the extent or severity of liver disease, the nature and timing of surgery, the type of anesthesia, and other comorbidities.

This study investigates the relationship between design patterns, modular architecture, and the maintainability of distributed real time systems developed using agile practices. Distributed real time systems are critical in various sectors, including telecommunications, healthcare, and automotive, where strict timing constraints and reliability are essential. Agile methodologies, known for their flexibility and iterative development, have been widely applied to software engineering, but their impact on long-term system maintainability, especially in complex real time environments, has been insufficiently explored. This research employs an empirical analysis, combining both quantitative and qualitative data from multiple real time system projects using agile methods. The analysis focuses on the application of design patterns, such as Singleton, Observer, and Factory, and evaluates the effectiveness of modular architectures in enhancing system scalability, flexibility, and long-term sustainability. The study also explores how agile practices contribute to system performance and maintainability, despite challenges related to frequent updates and coordination among distributed teams. Key findings show a positive correlation between the consistent use of design patterns and modularity, which significantly improves the maintainability and adaptability of distributed real time systems. This research also highlights the challenges faced by agile methods in maintaining architectural consistency and managing non-functional requirements, particularly in distributed environments. The results contribute valuable insights into adapting agile practices to meet the specific demands of distributed real time systems, offering recommendations for developers and project managers to incorporate modular architecture and design patterns to enhance long-term system sustainability. Further research is suggested to explore new design patterns and investigate the broader impact of agile methodologies on system quality beyond maintainability.

This qualitative inquiry examines the deliberate operational timing adopted by street vendors selling martabak, a popular Indonesian snack, exploring why nocturnal hours are strategically favored over daytime. The research methodology combined in-depth interviews with ten vendors operating in urban centers like Jakarta and Bandung with a consumer survey of one hundred respondents. Analysis of the collected data identifies a dual strategic foundation. From a demand perspective, night-time aligns with consumer psychology, fostering a leisurely atmosphere conducive to social snacking and impulsive purchases. On the supply side, vendors benefit from diminished direct competition, reduced operational overheads, and tapping into peak demand for evening treats. This synergy effectively cements martabak’s market identity as a beloved night-time culinary ritual linked to socialization. Consequently, the study posits that this chrono-marketing approach represents a savvy adaptation to local socio-economic rhythms. The insights derived provide a framework for micro-entrepreneurs to optimize service timing, aligning business operations with ingrained cultural consumption cycles to enhance sustainability and customer loyalty.  

This community service activity was conducted at Grind Now Coffee Bar, an MSME in Batam City’s food and beverage sector, to address challenges in managing raw material inventory, which often led to inaccurate stock records, shortages, and overstocking, affecting daily operations and efficiency.

These findings confirm that the integration of deep learning-based tolerance values contributes significantly to the effectiveness of classroom management and the strengthening of the social character of elementary school students.

Student selection for the National Student Sports Olympiad (O2SN), particularly in the karate category, is still largely conducted manually, which may lead to subjectivity and inconsistency in the assessment process. This study aims to design and develop a web-based Decision Support System (DSS) to assist schools in selecting the best students for the O2SN karate competition by applying the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method at SMA Negeri 2 Muaro Jambi. The system was developed using the waterfall model, which consists of requirement analysis, system design, implementation, and testing stages. The student evaluation process is based on criteria referring to the official O2SN karate standards, including stance accuracy, techniques, movement transitions, timing and harmony, breathing control, focus (kime), conformity (consistency with ryu-ha/style), strength, speed, and balance. The developed system processes assessment data to generate preference values and student rankings, which are separated by male and female categories. The results indicate that the application of the TOPSIS method is able to support more objective decision-making and improve transparency and efficiency in the O2SN student selection process within the school environment.
