h directly and indirectly. The research employed a quantitative approach with a cluster sampling technique across three regions Jambi City, Tanjung Jabung Timur Regency, and Merangin Regencywith a total of 132 respondents, 97 of whom were included in the analytical sample. Data were processed using SmartPLS 3.0 through structural model testing (inner model) to examine causal relationships among variables.The results indicate that leadership style does not have a significant direct effect on work motivation, whereas organizational culture shows a strong and significant direct effect on the work motivation of library staff. Additionally, leadership style and organizational culture jointly have a significant impact on work motivation. Regarding organizational commitment, the findings reveal that leadership style, organizational culture, and work motivation each have a positive and significant direct effect. Further results show that both leadership style and organizational culture exert significant indirect effects on organizational commitment through work motivation, suggesting that work motivation functions as a mediating variable in these relationships.
Overall, this study concludes that organizational culture is the most dominant factor influencing both work motivation and organizational commitment, while work motivation strengthens the relationship between leadership and cultural factors and the commitment of library staff. Therefore, efforts to enhance organizational commitment among library personnel in public senior high schools in Jambi Province should focus on cultivating a positive organizational culture, improving effective leadership practices, and providing continuous motivational support.

aging and relevant teaching materials. However, teachers still face challenges related to limitations in time, energy, technological understanding, and the accuracy of AI-generated content. Findings from the analysis show that AI has a significant capability to support teachers in designing learning materials relevant to student needs, as well as testing the accuracy of AI-generated content related to the learning material. Using a non-participant observation method, data was collected through social media, unstructured interviews with lecturers, teachers, and the general public, as well as testing the content of AI platforms such as ChatGPT, Gemini, and Meta AI. This research uses a descriptive qualitative approach to analyze the data. The study's findings reveal that artificial intelligence has a significant capacity to support educators in designing learning materials, while also optimizing time productivity and teaching innovation. However, the accuracy of AI content, although quite high for basic concepts, often does not include specific sources or references, thus requiring manual verification by teachers. The main challenges include a lack of training and technological understanding. It is recommended that teachers undergo AI training and always verify AI content with trusted sources.
Abstract:This study aims to analyze the influence of Transformational Leadership, Work Climate, and Skill Variety on the effectiveness of teacher work teams at Integrated Islamic Junior High Schools in the Riau Islands Province.…
The research uses a quantitative approach with a survey method. The sample consists of 120 teachers selected through proportional stratified random sampling. The research instrument is a Likert-scale questionnaire that has been tested for validity and reliability. Data analysis was carried out using Spearman correlation tests and non-parametric regression with the aid of SPSS version 29.00. The results show that all independent variables are positively and significantly related to teacher work team effectiveness (Transformational Leadership: ρ = 0.757; Work Climate: ρ = 0.795; Skill Variety: ρ = 0.767; p < 0.05). Non-parametric regression testing indicates a significant simultaneous effect (ρ = 0.000). Partially, Transformational Leadership (p = 0.253; p = 0.000), Work Climate (ρ = 0.355; p = 0.000), and Skill Variety (ρ = 0.282; p = 0.000) significantly influence teacher work team effectiveness. Work climate is proven to be the dominant factor affecting team effectiveness. The implications of this study affirm that improving teacher work team effectiveness must be carried out holistically through strengthening school principals’ transformational leadership, creating a conducive work climate, and developing teachers’ skill variety.
Abstract:Urine alcohol testing plays a vital role in detecting alcohol consumption for clinical and forensic purposes, yet its results may be influenced by pre-analytical factors such as the delay between sample collection and laboratory…
boratory analysis. This study aimed to evaluate the effect of delay time before urine examination on alcohol concentration. An experimental One-Shot Case Study design was conducted involving 44 participants in Denpasar who had consumed alcohol. Alcohol concentration was measured immediately, after a 2-hour delay, and after a 4-hour delay using the Alcohol Urine Rapid Test Dipstick Allchek, and the data were analyzed using the Kruskal-Wallis test. The findings showed that average urine alcohol levels increased numerically after a 2- and 4-hour delay compared to immediate testing; however, this change was not statistically significant (p=0.131). These results confirm that delaying urine alcohol examination up to 4 hours does not significantly alter detectable alcohol concentrations, although prompt testing is still recommended to ensure result accuracy and minimize the risk of false positives. This study provides important insights for the development of standard operating procedures regarding urine alcohol analysis in laboratory practice.

Therefore, the null hypothesis (H₀) is rejected, and the alternative hypothesis (H₁) is accepted, meaning there is a significant difference in students’ speaking skills before and after being taught using hand puppet media.
Abstract:The intensive use of synthetic chemical pesticides in agriculture has led to various negative impacts on the environment and human health, as well as increased pest resistance. As an alternative, plant-based pesticides (botanical…
botanical insecticides) have shown potential due to their eco-friendly and sustainable nature. This study aims to review the effectiveness of soursop (Annona muricata) leaf extract as a botanical pesticide against the gray caterpillar (Spodoptera litura) on mustard plants (Brassica juncea), using a literature review method. Data were collected through a systematic search of accredited national and international scientific journals, then analyzed descriptively and comparatively. The findings indicate that soursop leaves contain bioactive compounds such as acetogenins, flavonoids, and saponins, which act as stomach poisons, antifeedants, and repellents to S. litura. Several studies reported that extracts from Annona spp. leaves and seeds effectively inhibit larval growth, reduce feeding activity, damage digestive tissues, and lead to larval death. This effectiveness highlights the potential of soursop leaves as a safe and efficient candidate for botanical pesticide development. The study also identifies a research gap regarding field-scale testing on mustard plants, suggesting the need for further agronomic validation.
Abstract:Dengue Hemorrhagic Fever (DHF) is a viral infection marked by a significant decrease in platelet count. Accurate platelet count testing is crucial for diagnosing and monitoring DHF patients. The pre-analytical phase is a…
critical stage in laboratory testing, where errors can significantly impact test outcomes. Anticoagulants, such as K3EDTA and 3.2% sodium citrate, are commonly used in routine hematology tests to prevent blood clotting by binding calcium ions and inhibiting clotting factor activation. This study aimed to evaluate the difference in platelet counts between blood samples collected with K3EDTA and 3.2% sodium citrate anticoagulants in DHF patients. An analytical observational study with a cross-sectional design was conducted involving 50 purposively sampled DHF patients. Statistical analysis yielded a p-value of 0.615 (p > 0.05), indicating no significant difference in platelet counts between the two anticoagulants. It can be concluded that the use of K3EDTA and 3.2% sodium citrate does not significantly affect platelet count results in DHF patients. Future studies are recommended to involve larger sample sizes and consider microscopic examination methods, such as peripheral blood smears, to assess platelet aggregation visually.

utilized, resulting in low economic value and its potential as a food source has not been maximized. One solution to overcome this problem is to use organic land kale as an alternative ingredient for making nori. Organic land kale is known to have good nutritional content and is commonly consumed by the community. This study aims to determine the level of acceptance of analog nori made from organic land kale as a healthy snack through organoleptic tests. The method used was an experiment with a completely randomized design (CRD), consisting of 24 samples, 6 treatments, and 4 repetitions. The treatment given was carrageenan concentration (0%, 0.6%, 0.8%, 1%, 1.2%, and 1.4%) Data were analyzed using the Friedman Test to assess panelists' preferences for taste, color, aroma, and texture parameters. It can be concluded that the results show the addition of carrageenan at 1% produces analog nori with the highest level of acceptance, so it is considered the most optimal formulation.
Abstract:Cardiovascular disease remains a leading cause of death both globally and nationally, with Low Density Lipoprotein(LDL) levels serving as a key biochemical indicator in the screening and management of heart disease. Accurate…
rate LDL testing requires adherence to pre-analytical procedures, particularly fasting for 10-12 hours. This study aimed to describe LDL levels and fasting compliance among outpatient cardiac patients at RSU Prima Medika Denpasar. A descriptive cross-sectional design was used with purposive sampling, involving 35 cardiac outpatients from February to March 2025. Data were collected through interviews and laboratory examinations using the Furuno CA-270 device. Results showed that 71% of respondents had LDL levels >100 mg/dL, indicating high levels, while 29% hadnormal levels (<100 mg/dL). All respondents (100%) complied with the fasting requirement. These findings indicate that high LDL levels are still commonly found among outpatient cardiac patients, particularly in productive-age males. The high level of fasting compliance reflects the effectiveness of pre-analytical patient education. This study emphasizes the importance of routine lipid screening and continuous education to enhance laboratory diagnostic accuracy and prevent cardiovascular complications.
