Government procurement plays a strategic role in supporting effective, efficient, transparent, and accountable public administration. To promote procurement reform, the government has implemented an electronic procurement system through the Electronic Procurement Service (LPSE). The implementation of the Electronic Procurement System (SPSE) in Pematang Siantar City aims to improve procurement quality, reduce irregularities, and accelerate the delivery of goods and services. However, several challenges persist, including limited human resources capable of operating the system, technical disruptions, lack of outreach to local vendors, and weak coordination between the Procurement Unit (UKPBJ) and related agencies. This study aims to analyze the effectiveness of SPSE implementation in Pematang Siantar City. The research uses a descriptive qualitative approach. Data were collected through interviews with UKPBJ officials and procurement officers from several local government units, direct observation of procurement activities via SPSE, and documentation review. Data analysis employed Duncan’s effectiveness indicators: goal attainment, integration, and adaptation. The results show that SPSE implementation has not been fully effective. In terms of goal attainment, procurement processes follow established procedures, but delays still occur due to system disruptions and limited user competence. In terms of integration, coordination between UKPBJ and technical units remains suboptimal, affecting communication and oversight. Regarding adaptation, although the information technology infrastructure is adequate, human resource capacity is still limited. Therefore, improving human resources, strengthening coordination, and enhancing system reliability are necessary to achieve optimal effectiveness.

These findings suggest that Dakpin media is appropriate and effective as a learning tool to support students’ understanding of GCF and LCM concepts in elementary mathematics learning.

This study aims to examine how nepotism can manifest through the role of informal institutions and its influence on administrative integrity within the bureaucracy. The method used is literature analysis by examining various related scientific references, such as books, journal articles, and research, which are then analyzed descriptively and analytically through identification, classification, and data integration. The research findings indicate that nepotism does not only arise from weaknesses in the official system, but is also strongly influenced by the existence of informal institutions such as personal networks, social norms, and organizational culture. This practice tends to persist within a system because it gains social recognition, making it difficult to overcome solely with regulations. The consequences include a decline in employee professionalism, weak accountability, and erosion of administrative integrity, which impacts on reduced public trust in government institutions. The implications of this study indicate that a comprehensive approach is crucial in bureaucratic reform, through strengthening the official system and changing organizational cultural values ​​to produce transparent, accountable, and dignified government management.

The rapid growth of digital technology and social media has reshaped communication practices, consumer behavior, and marketing approaches, particularly among Generation Z, who are widely recognized as digital natives. For this generation, social media serves as a major channel for obtaining information and exploring product references before making purchase decisions. In this environment, influencer marketing has emerged as a prominent promotional approach because it can foster audience interaction, emotional connection, and trust more effectively than conventional advertising. This study examines the role of influencer marketing in shaping the digital behavior of Generation Z in Indonesia. A qualitative literature review method was employed by analyzing secondary sources drawn from academic journals, books, and related publications. The findings indicate that influencer marketing has a meaningful influence on information-seeking behavior, decision-making processes, and the level of digital engagement among Generation Z. Influencers are commonly viewed as more credible, relatable, and authentic sources of information. Furthermore, the effectiveness of influencer marketing is determined more by credibility, authenticity, and the quality of interaction than by follower count alone. These findings suggest that companies should adopt digital marketing strategies that are more interactive, personalized, and relationship-oriented in order to engage Generation Z more effectively.

Therefore, hospitals should enhance communication training and interprofessional collaboration programs to improve healthcare quality and patient safety

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.

World Health Organization (WHO) reports that immunization is able to prevent approximately 3–5 million deaths each year; however, a number of children still do not receive optimal immunization coverage due to insufficient parental knowledge. This study aimed to analyze the effect of health education on improving mothers’ knowledge regarding early childhood immunization in RW 04, Kertamaya Subdistrict, Bogor City, in 2026. 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.

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.

This study aims to analyze the skills gap in the era of the Industrial Revolution 4.0 and the factors influencing it. The research employed a descriptive-analytical approach based on literature studies and the author’s analysis of the dynamics of formal education curricula and the development of industrial needs. The findings indicate that formal education curricula that are less adaptive to technological developments are the main factor causing the skills gap. In addition, the slow adaptation to technology in educational and industrial environments, as well as the unequal distribution of skills development across various regions in Indonesia, further widen the gap between graduates’ competencies and labor market demands. This condition affects the low readiness of the workforce in facing digital transformation and global competition. The study concludes that the skills gap is a strategic issue requiring serious attention from the government, educational institutions, and the industrial sector. Curriculum reform that is responsive to technological advancements, strengthening digital literacy, and ensuring equal access to training and skills development are essential steps to improve the competitiveness of Indonesian human resources. These efforts are expected to support poverty reduction, reduce social inequality, and achieve the long-term national development goals toward Indonesia Golden Vision 2045.

This study employed a pretest–posttest design with health counseling provided to 25 pregnant women and Women of Reproductive Age in RW 05, Kertamaya Subdistrict, Bogor City. Data were collected using knowledge and attitude questionnaires before and after the counseling and analyzed using the Paired Sample T-test. The results showed a significant increase in participants’ average knowledge and attitude scores after the educational intervention (p < 0.05). Based on the Paired T-test, the intervention yielded a p-value of 0.000, indicating a statistically significant improvement in both knowledge and attitudes. These findings demonstrate that health education is effective in increasing knowledge and fostering positive attitudes regarding hypertension among pregnant women and Women of Reproductive Age.

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.

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.

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.
