This study aims to analyze the influence of the Problem Based Learning (PBL) model in science education on students’ environmental literacy and science communication skills at SMK Negeri 3 Pekanbaru, focusing on the topic of disaster mitigation. The research employed a causal comparative approach with a post-test only design, comparing two student groups: an experimental class using the PBL model and a control class using conventional teaching. The results revealed a significant difference in environmental literacy, with the experimental class achieving a higher average score (81.86) compared to the control class (62.05). This indicates that the PBL model is effective in enhancing students' understanding, awareness, and environmentally responsible behavior. The PBL approach encourages active student engagement and the application of knowledge to real-world scenarios, which is particularly beneficial in the context of environmental issues and disaster mitigation. By working through problems related to environmental challenges, students are likely to gain a deeper understanding of the topic, which fosters a sense of responsibility towards environmental sustainability. In terms of science communication, although the experimental class showed a higher average score (75.78) than the control class (72.92), the difference was not statistically significant. This may be due to a lack of intensive training in scientific discussions and presentations. While PBL encourages collaborative problem-solving and idea-sharing, students may still require more structured practice in presenting and communicating their findings clearly and persuasively. The integration of more structured activities focusing on science communication skills could further enhance the effectiveness of the PBL model. Overall, the PBL model demonstrates positive potential in improving both environmental literacy and science communication. However, to achieve its full impact, its implementation must be consistent, with a focus on providing students with additional opportunities to develop their communication skills.

Feed is a key component in catfish (Pangasius hypophthalmus) cultivation because it directly affects the growth rate, health, and productivity of the fish. Among the various nutrients contained in feed, protein plays a crucial role, particularly in the formation and repair of fish body tissues. Adequate protein content supports optimal growth, while protein deficiency can reduce productivity. Therefore, analyzing protein levels in feed is essential to ensure its quality. This study aimed to analyze protein levels in catfish feed using the Kjeldahl method. The analysis was conducted at the Pekanbaru Center for Standardization and Industrial Services (BSPJI). The Kjeldahl method was chosen because it is known to have a high level of accuracy and reliability. The procedure involves three main stages: destruction, distillation, and titration. The working principle of this method is to convert organic nitrogen in the sample into ammonia, which is then captured and measured to determine nitrogen levels, which are then converted to protein levels. In this study, five feed samples with codes U-139 to U-142 were used. The test results showed that the protein content of the samples ranged from 20.44% to 23.09%. Furthermore, a Relative Percent Difference (RPD) value of 0.0013% was obtained, indicating a very high level of measurement precision. The analysis results were then compared with the fish feed quality standards based on SNI 2534:2006, and it was found that all samples met the minimum protein content requirements. Thus, this study confirms the effective and accurate use of the Kjeldahl method in analyzing protein content in catfish feed. These results also provide important information for farmers and feed producers in ensuring the quality of feed used to support catfish farming productivity.

Bullying is a persistent social issue frequently found in school settings and remains a concern in many countries. This study was initiated based on observations at SMPN 17 Pekanbaru, where numerous students were found to have experienced bullying. The purpose of this community service program was to introduce and promote a digital reporting platform for junior high school students, designed to be safe, interactive, and evidence-based, thereby enabling victims or witnesses to report incidents more easily. The methods applied included socialization, practical demonstration, and evaluation, involving 40 students as participants in the program. The intervention introduced the “BeSafe” website, which aims to provide a secure and user-friendly channel for reporting bullying anonymously and independently. The findings indicate that the website achieved a usability score of 82.2%, categorizing it as highly feasible and appropriate for use among adolescents. Furthermore, BeSafe was able to offer comfort, security, and accessibility for students in addressing bullying cases. An evaluation carried out one month after the program revealed that 20 bullying complaints had been successfully submitted through the platform, showing its effectiveness in encouraging students to speak up and utilize digital solutions without fear of exposure. In conclusion, the BeSafe platform is proven to be suitable as a medium for reporting bullying cases and holds significant potential to support preventive measures in schools. Beyond serving as a reporting tool, it can also act as an educational and protective medium that fosters a safer, more inclusive, and supportive school environment, ultimately contributing to the broader efforts of reducing bullying and enhancing students’ psychological well-being.

This study aims to analyze the sentiment of customer reviews of the Grand Jatra Hotel Pekanbaru on the Google Review platform using the Naïve Bayes algorithm. Social media and online review platforms are increasingly becoming the primary source of information for potential customers in making purchasing decisions, particularly in the hospitality sector. Therefore, sentiment analysis of customer reviews is crucial for understanding consumer perceptions and providing strategic input for hotels in improving service quality. The research data was collected using web scraping techniques to obtain publicly available customer reviews. The obtained data was then processed through text preprocessing stages including case folding, tokenizing, normalization, stopword removal, and stemming. The Term Frequency-Inverse Document Frequency (TF-IDF) method was then used to weight each word, so that more relevant words have a greater influence in the classification process. The sentiment classification process was carried out into two main categories, namely positive and negative. The Naïve Bayes model was trained using training data and then tested with test data to measure the algorithm's performance in classifying sentiment. The evaluation results show that the model built is able to achieve an accuracy level of 98%, with a precision value of 97% and a recall of 100% in the positive class, and 92% in the negative class. These findings confirm that the Naïve Bayes algorithm can be effectively used in analyzing customer sentiment towards hotel services and facilities. Practically, the results of this study are expected to provide insight for the management of Grand Jatra Hotel Pekanbaru in understanding customer perceptions, identifying service strengths and weaknesses, and formulating more targeted marketing strategies. In addition, this study can also be a reference for the development of similar studies in the hotel industry and other service sectors.

Clean and Healthy Living Behavior (PHBS) is an important component in creating healthy living habits, especially in elementary school children. Education about PHBS needs to be instilled from an early age to form a sustainable healthy lifestyle. This study aims to determine the effect of interactive education on improving the understanding of second-grade students at Dharma Loka Elementary School Pekanbaru regarding PHBS. In this study, 50 students were involved using a pre-experimental design through the One Group Pretest-Posttest Design method. The educational intervention was carried out using interactive instructional games such as snakes and ladders, animated films, and PowerPoint presentations. The results showed an increase in students' understanding of PHBS after the intervention. The average score of students in the initial test was 93.2, while after the intervention, the average score increased to 100, with an increase of 6.8 points. This indicates that interactive learning has a positive impact on students' understanding of PHBS. Learning that involves teaching aids and games is proven to be more interesting for elementary school students, making them more active in the learning process. Interactive education not only improves students' understanding but also encourages them to apply PHBS more in their daily lives. The use of media such as games, animated films, and PowerPoint presentations facilitates a more comprehensive and enjoyable understanding. Therefore, this approach can be an effective strategy for teaching children healthy lifestyles, while providing a fun and rewarding learning experience. This interactive education also provides students with the opportunity to learn in a more enjoyable and less boring way. Through the snakes and ladders game, students can learn the concept of healthy living (PHBS) directly in a lighter and more entertaining way. Animated films and PowerPoint presentations add variety to the learning method, making the information conveyed more easily by students.

This study was conducted at Family Pharmacy in Pekanbaru City with the objective of examining the relationship between emotional intelligence and work stress, as well as their combined effect on employee performance. The research population consisted of all 150 employees in the production department. Using the Slovin formula, a sample of 60 respondents was selected through accidental sampling. Data collection was carried out via an online questionnaire distributed through Google Forms. The analytical methods employed were correlation analysis to assess the relationship between variables and multiple linear regression to measure their simultaneous influence on performance. The results indicated a negative relationship between emotional intelligence and work stress, meaning that employees with higher emotional intelligence tended to experience lower levels of work stress. Furthermore, when examined together, emotional intelligence and work stress had a significant impact on employee performance. Specifically, these two variables contributed 47.4% to the variance in performance, while the remaining 52.6% was influenced by other factors not addressed in this study.

This study emphasizes the importance of implementing systematic risk management for small and medium businesses in order to be able to compete sustainably and maintain customer trust.

The school uniform policy is part of the broader education policy aimed at instilling the values of nationalism, social equality, discipline, and fostering a spirit of unity among students. However, in its implementation in Pekanbaru City various issues are still found, such as the financial burden placed on parents for purchasing uniforms, lack of transparency from schools, and suboptimal parental involvement and supervision by the education office. This study employs a qualitative method with a descriptive phenomenology approach. The research refers to the policy implementation theory of Yulianto Kadji, namely the MSN Approach (Mentality-Approach, System-Approach, and Networking-Approach). Data were collected through in-depth interviews, direct observation, and documentation. Informants included representatives from the Pekanbaru City Education Office, school principals, and parents. The results of the study indicate that the implementation of the school uniform policy in Pekanbaru City has not been optimal. From the mentality approach, there are still objections from parents regarding the cost of uniforms and limited understanding of the policy regulations. From the systems perspective, regulations are not consistently enforced by schools, including a lack of prioritization for underprivileged students and the absence of strict sanctions for policy violations. Meanwhile, from the networking approach, parental involvement and the role of school committees in decision-making remain weak, resulting in the lack of effective strategic partnerships between schools, parents, and the education office.

Slum areas in Pekanbaru City are being addressed by the local government, including the Meranti Pandak Sub-district. This study aims to assess the effectiveness of the Meranti Pandak Sub-district government in maintaining environmental cleanliness in slum areas and to identify the inhibiting factors affecting its effectiveness (Case Study: Slum Area in Meranti Pandak Sub-district, Pekanbaru City). Environmental issues in this area are of major concern due to their impact on public health and quality of life. The study applies Duncan’s theory (as cited in Nurmalasari & Supriyadi, 2021), which highlights three indicators: goal achievement, integration, and adaptation. Data collection methods include observation, interviews, and documentation. The findings reveal that the sub-district government's efforts have not been fully effective. This is evident from poorly targeted programs, unequal service distribution among residents, low community participation, and weak monitoring and evaluation by the local authorities. Additional obstacles include unresolved waste management issues, limited budget, and non-permanent building structures. To improve effectiveness, the study recommends more focused program planning, sustainable community empowerment, and enhanced cross-sectoral coordination.
