Recent Internet of Things (IoT) intrusion detection studies have reported near-perfect benchmark performance for Distributed Denial of Service (DDoS) detection, yet limited attention has been given to understanding how different traffic representations contribute to the detection process under highly imbalanced traffic conditions. This study presents an ablation-driven analysis to investigate the contribution of statistical and temporal representations for large-scale IoT DDoS detection using the CICIoT2023 dataset. Three experimental scenarios are evaluated, including statistical representation, temporal sequence representation, and hybrid statistical–temporal representation. Temporal representations are learned using a one-dimensional Convolutional Neural Network (1D-CNN) with lag-based traffic sequences, while ensemble tree-based classifiers are employed for final classification and representation analysis. In addition, multiple ablation configurations are designed to evaluate the impact of temporal dependency modeling and feature engineering strategies on detection performance. Experimental results show that statistical traffic representations remain highly effective for DDoS detection on CICIoT2023, achieving 99.36% accuracy and 99.31% weighted F1-score in the statistical representation scenario. Feature importance analysis further indicates that engineered statistical features contribute substantially more to the classification process than CNN-based temporal representations. Although temporal modeling captures sequential traffic behavior, its contribution is relatively limited and mainly acts as a complementary representation. Furthermore, the hybrid configuration produces only marginal improvements over the statistical representation alone. These findings highlight the importance of representation-level analysis for understanding the actual contribution of statistical and temporal modeling in modern IoT intrusion detection systems beyond relying solely on benchmark accuracy.

Vegetable stall businesses represent a common form of micro-enterprise that meets consumers' daily needs, including in the Depok District. However, most business owners have yet to adopt proper and adequate financial record-keeping practices, relying instead on manual methods. This makes it difficult to control and evaluate business financial management. This community engagement initiative aimed to provide guidance on digitizing accounting records for vegetable stall MSMEs using the BukuWarung application and to enhance the digital financial literacy of business owners regarding digital financial management. A quantitative descriptive approach was employed, involving observation, interviews, documentation, and direct assistance provided to vegetable stall owners in the Depok District. Observations revealed that business owners gained a better understanding of and improved skills in using the BukuWarung application, becoming capable of independently recording income, expenses, and business receivables and payables. The initiative demonstrated that implementing a guidance program for digitizing accounting records via the BukuWarung application significantly contributed to improving the financial management capabilities of vegetable-trading MSMEs. These findings suggest the potential for applying similar guidance models to MSMEs in other regions to foster broader digital financial literacy.

Job analysis is a key component of human resource management that plays a role in determining the tasks, responsibilities, and competencies required for a particular job. In various organizations, job analysis serves as the foundation for HR planning, recruitment, selection, employee placement, and performance evaluation. However, research on job analysis remains scattered across various studies focused on specific organizational contexts, necessitating a literature synthesis to gain a more comprehensive understanding of research developments in this field. Therefore, this study aims to analyze the development of research on job analysis and identify its role and contributions to human resource management. This study employed a literature review method by searching for scientific articles in the Google Scholar database using the Publish or Perish (PoP) application with the keyword “job analysis.” The initial search yielded 30 scientific articles, which were then screened based on topic relevance, open access, and publication years ranging from 2020-2026, resulting in 16 articles selected for further analysis. The findings indicate that the literature on job analysis can be grouped into three main themes: the role of job analysis in human resource management, its contribution to improving employee performance and productivity, and its implementation in employee placement and organizational governance. Overall, job analysis has proven to be a strategic tool for enhancing the effectiveness of human resource management. Further research is recommended to examine the implementation of job analysis in greater depth across various organizational contexts to enrich the development of human resource management theory and practice.

This study aims to examine the traces of acculturation between Islam and local culture in Margorejo Village, Kerek District, Tuban Regency. The research is based on the understanding that the spread of Islam in Indonesia occurred peacefully, persuasively, and adaptively, allowing Islamic teachings to interact harmoniously with local traditions without eliminating existing cultural identities. This process produced forms of religious culture that combine Islamic values with local customs and continue to be preserved by the community. The study employed a qualitative descriptive approach. Data were collected through observation, interviews with religious leaders, community leaders, and local residents, as well as documentation of religious and social traditions. Data analysis was conducted through data reduction, presentation, and conclusion drawing. The findings show that acculturation is reflected in the tradition of pilgrimage to the tomb of Sheikh Ahmad Subaqir or Mbah Mboja, who is regarded as an important figure in spreading Islam in the region. The pilgrimage serves not only as a spiritual activity but also as a means of strengthening social solidarity. Another form of acculturation appears in the “sedekah bumi” or “manganan” tradition, which expresses gratitude for agricultural harvests and community welfare. The study concludes that Islam and local culture in Margorejo coexist harmoniously and contribute to strengthening religiosity, social solidarity, and cultural preservation.

Drowning is one of the leading causes of accidental death worldwide and remains a major challenge in forensic investigations due to the complexity of determining the exact cause and mechanism of death. This study aimed to analyze forensic investigation methods used to determine the cause of death in drowning cases. The research employed a qualitative descriptive literature review approach by analyzing scientific articles, forensic journals, and medical references related to drowning investigations. Data were collected through literature searches from Google Scholar, PubMed, and Portal Garuda using keywords related to forensic drowning investigations. The findings indicate that forensic investigation in drowning cases requires a comprehensive approach involving external examination, autopsy, laboratory examination, histopathology, diatom analysis, toxicology, and crime scene investigation. Typical forensic findings include foam cone, washerwoman’s hands, cutis anserina, emphysema aquosum, and the presence of foreign materials in the respiratory and digestive tracts. Diatom examination and histopathological analysis also play important roles in strengthening the diagnosis of drowning. The study concludes that an integrated forensic investigation based on scientific evidence is essential to accurately determine the cause and manner of death in drowning cases and to support medicolegal processes in Indonesia.

Health issues among the elderly are often related to declining bodily functions, digestive disorders, and specific nutritional needs for easily digestible foods. The 60-and-older age group is at high risk for gastrointestinal disorders due to low fiber intake. Therefore, alternative foods are needed that are soft in texture, neutral in taste, safe, and nutritious. One potential solution is the development of food products based on tempeh gembus with the addition of banana hearts, which are rich in fiber, soft in texture, and readily available. This study employed an experimental method using a Completely Randomized Design (CRD) to test three formulation variations (F1, F2, F3). The nutritional content of formulation F1 includes energy 111.575 kcal, carbohydrates 20.185 g, protein 6.91 g, fat 0.355 g, and fiber 6.67 g. Formula F2 contains 88.225 kcal of energy, 14.095 g of carbohydrates, 7.72 g of protein, 0.205 g of fat, 7.3 g of fiber, and 0.0015% flavonoids. Formula F3 has 107.015 kcal of energy, 7.995 g of protein, 0.295 g of fat, 6.88 g of fiber, and 0.0021% flavonoids. In conclusion, the best tempeh with added banana hearts is Formula F2, with its nutritional content, fiber, flavonoids, and BAL >10⁸ CFU/g, which has the potential to serve as a functional food and probiotic source to help improve digestive health in the elderly. Further testing is recommended directly on elderly groups, along with product shelf-life testing.

This research investigates the effect of the amount of MSMEs, the number of buildings, and GRDP on regional tax revenue in selected cities and regencies in South Sulawesi, driven by the inconsistency between the growth of economic potential and the realization of tax revenue, where increases in MSMEs, buildings, and GRDP are not always followed by higher tax receipts. The study aims to analyze the effect of these variables and identify the most significant factors contributing to regional fiscal capacity. A quantitative approach is employed using panel data that combine time series and cross-sectional data from 2015-2024, analyzed through panel data regression with model selection based on Chow, Hausman, and Lagrange Multiplier test. The results show that partially, MSMEs and the number of buildings do not have a significant effect on tax revenue, while GRDP has a positive significant impact; however, simultaneously, all variables significantly influence tax revenue, as indicated by a high Adjusted R-squared value. These findings suggest that economic growth, as proxied by GRDP, plays a more dominant role in increasing tax revenue compared to the mere increase in the number of MSMEs and buildings, implying that optimizing tax revenue requires not only expanding economic potential but also enhancing tax compliance, administrative efficiency, and the quality of economic growth.

Effective communication is essential for teamwork effectiveness in healthcare, particularly in inpatient units where patient care requires coordination among multiple professionals. Internal data from Hospital X showed that more than 50% of medical incidents in the last two years were related to miscommunication among healthcare workers.

This study aimed to examine the influence of effective communication on teamwork effectiveness with interprofessional collaboration as an intervening variable at Hospital X.This study used a quantitative cross-sectional design involving 226 healthcare workers, including doctors, nurses, and medical support staff. Data were analyzed using the Three-Box Method and PLS-SEM. The findings revealed that effective communication significantly influenced teamwork effectiveness both directly and indirectly through interprofessional collaboration. Interprofessional collaboration also acted as a significant mediating variable between communication and teamwork effectiveness. These results indicate that communication is a key foundation for strengthening collaboration and improving teamwork in hospitals. Therefore, hospitals should enhance communication training and interprofessional collaboration programs to improve healthcare quality and patient safety

The academic transition phase among tenth-grade students represents an important period that requires the ability to adjust to changes in the environment, academic demands, and increasingly complex social dynamics. This study aims to analyze psychosocial dynamics in the student adaptation process during the academic transition phase through a literature review approach. The method employed was a library research study by examining various relevant scientific sources related to adolescent psychosocial development, adaptation processes, psychosocial impacts, and strategies for addressing students’ adaptation problems. The results of the review indicate that the adaptation process is influenced by both internal and external factors. Internal factors include emotional condition, coping ability, and self-control, while external factors include support from family, peers, teachers, and the school environment. Students’ inability to adapt may lead to anxiety, low self-confidence, academic difficulties, and obstacles in social interaction. Efforts to support students’ adaptation process can be carried out through strengthening social support, optimizing guidance and counseling services, and implementing self-management techniques to enhance students’ self-regulation abilities. With appropriate support and intervention strategies, students are expected to navigate the academic transition phase more effectively and develop optimally in psychological, social, and academic aspects.

Gestational hypertension is one of the leading causes of maternal mortality in Indonesia. Non-pharmacological interventions such as lavender aromatherapy have gained attention as complementary therapies due to their natural properties and minimal side effects. This study aims to evaluate the effect of lavender aromatherapy on blood pressure among pregnant women with gestational hypertension. The research employed a quasi-experimental design using a one-group pretest-posttest approach. A total of 15 participants meeting the inclusion criteria received an intervention consisting of lavender aromatherapy inhalation for 10–15 minutes. The results showed a decrease in mean systolic blood pressure from 141.53 mmHg before the intervention to 139.27 mmHg after the intervention. However, the mean diastolic blood pressure slightly increased from 90.20 mmHg to 90.27 mmHg. The reduction in systolic pressure indicates a potential relaxation effect of lavender, likely mediated through parasympathetic nervous system stimulation. Although the change in diastolic pressure was minimal and not clinically significant, these findings support the use of lavender aromatherapy as a supportive approach in managing blood pressure in pregnant women with gestational hypertension. This complementary therapy is expected to enhance maternal healthcare, particularly in improving comfort and reducing stress during pregnancy.

This study employed a pre- experimental design with a one-group pretest–posttest approach involving 30 respondents. Knowledge levels were measured using a questionnaire before and after the health education intervention and analyzed using the Paired Sample T-Test. The results indicated a statistically significant difference in mothers’knowledge levels before and after the health education intervention (p = 0.029). In addition, the proportion of respondents with good knowledge increased from 76.7% in the pre-test to 93.3% in the post-test. These findings demonstrate that health education has a significant effect on improving mothers’ knowledge and can serve as an effective promotive intervention to support the success of community-level immunization programs.

This study aims to analyze the role of the Regional Disaster Management Agency (BPBD) of East Flores Regency in managing the eruption disaster of Mount Lewotobi Laki-Laki during the pre-disaster, emergency response, and post-disaster phases. The study employed a descriptive qualitative method involving 18 informants from BPBD and affected communities in Wulanggitang and Ile Bura Sub-districts. Data were collected through observation, interviews, and documentation. The findings show that during the pre-disaster phase, BPBD implemented preparedness measures through disaster-prone area mapping, the establishment of Disaster Preparedness Teams and Disaster-Resilient Villages, public outreach, and the use of local wisdom. However, outdated contingency plans, limited early warning systems, weak relocation efforts, and low public awareness contributed to panic and casualties during the eruption. In the emergency response phase, BPBD successfully coordinated evacuation efforts, established emergency posts, and distributed logistics effectively. Nevertheless, displaced communities experienced discomfort due to prolonged emergency conditions and limited fulfillment of basic needs in temporary shelters. In the post-disaster phase, BPBD conducted rehabilitation and reconstruction through transportation recovery, trauma healing programs, and permanent housing development based on the Rehabilitation and Reconstruction Plan (R3P). However, limited funding and delays in reconstruction processes remained major challenges. Therefore, improving coordination, institutional capacity, disaster communication, and community participation is essential for effective disaster management.

Embroidery learning in fashion design education requires technical mastery, creativity, perseverance, collaboration, and the ability to produce aesthetically valuable products. However, student motivation often decreases when practical learning is dominated by lecturer explanation and imitation of examples. This study aims to determine the effect of Team-based Projects in embroidery learning on student learning motivation. A quantitative approach was employed using a quasi-experimental pretest-posttest control group design. The sample consisted of 60 students divided into an experimental class and a control class. The experimental class received team-based project learning, while the control class followed conventional individual practice. Data were collected using a learning motivation questionnaire based on intrinsic motivation, extrinsic motivation, and amotivation. The data were analyzed through normality tests, homogeneity tests, paired sample t-tests, independent sample t-tests, and simple linear regression. The findings showed that the experimental class’s motivation score increased from 67.83 to 82.37 after the treatment. The independent sample t-test revealed a significant difference between the experimental and control classes, with a p-value < 0.001. Regression analysis also confirmed that Team-based Projects positively affected student learning motivation. These results indicate that team based embroidery projects create more meaningful, collaborative, and challenging learning experiences.

Tourism in Bali, as the backbone of the regional economy, absorbs more than 50% of the workforce and gives rise to complex labor dynamics. Although Law No. 13 of 2003 on Manpower and Law No. 21 of 2000 on Trade Unions guarantee worker protection and freedom of association, the reality on the ground is still marked by the misuse of fixed-term employment contracts (PKWT), violations of outsourcing regulations, and both structural and cultural barriers to union formation. This article employs a normative juridical approach, using statute, conceptual, and case-based methods to analyze the regulatory framework and the responses of workers, employers, and government actors in addressing industrial relations disputes within Bali’s tourism sector. The findings reveal a significant gap between written legal norms and actual practice: repeated extensions of PKWT, outsourcing of core tasks such animal caretaking, union-busting through dismissal of union members, and weak law enforcement at regional level. Trade unions play a role in mediation and advocacy, but their performance is hindered by employer intimidation, low legal literacy among workers, and limited institutional support. Bridging this gap requires strict oversight, legal education for workers, as well as the strengthening of union capacity and the authority of local governments.

This study aims to describe the implementation of the Problem-Based Learning Strategy (PBLS) in Arabic language learning for eighth-grade students at MTs Negeri 4 East Tanjung Jabung, as well as identify supporting factors, inhibiting factors, and efforts to overcome those obstacles. This research employed a descriptive qualitative approach using observation, interviews, and documentation techniques. The research subjects included the principal, Arabic language teacher, and eighth-grade students. The findings revealed that PBLS was implemented through stages of problem presentation, information identification, group discussion, presentation, and evaluation. This strategy improved students’ active participation, critical thinking skills, communication abilities, and understanding of Arabic learning materials. Supporting factors included teacher professionalism, adequate facilities and infrastructure, and support from the school environment. Inhibiting factors included students’ low reading interest, limited instructional time, and differences in students’ characteristics and abilities. Efforts to overcome these obstacles involved providing motivation, forming heterogeneous groups, effective time management, and utilizing simple and engaging learning media. Therefore, PBLS is considered effective in Arabic language learning because it enhances both the learning process and student learning outcomes.

This study was motivated by the fact that students still experience difficulties in understanding Nahwu and Shorof despite studying both sciences in Islamic boarding schools. The purpose of this research was to examine the perspectives of Arabic language, Nahwu, and Shorof teachers regarding the importance of Nahwu and Shorof in Arabic language learning, their understanding of the concepts and applications, and the effectiveness of learning implementation at Madrasah Aliyah Al-Hidayah East Tanjung Jabung. This research employed a descriptive qualitative approach using interviews, observations, and documentation as data collection techniques. Data analysis was conducted through data reduction, data presentation, and conclusion drawing, while data validity was ensured through source and technique triangulation. The findings revealed that teachers considered Nahwu and Shorof as the fundamental basis of Arabic language learning because these sciences regulate sentence structures, word transformations, and meanings in Arabic texts. Teachers believed that mastery of Nahwu and Shorof is essential for understanding the Qur’an, hadith, and classical Islamic books. The learning process was considered fairly effective since many students already had prior knowledge from pesantren education and showed progress during the learning process. However, the effectiveness of learning still faced several obstacles, including low student motivation, differences in students’ basic abilities, limited learning time, and the complexity of the material. This study concludes that improving the quality of Nahwu and Shorof learning requires more varied teaching methods, continuous motivation, regular material reinforcement, and stronger institutional support.
