The rapid growth of e-commerce in Indonesia, particularly the Shopee platform, has generated a large volume of user reviews on the Google Play Store, which can be analyzed to understand consumer sentiment. This study aims to compare the performance of the Support Vector Machine (SVM) and Random Forest (RF) algorithms in binary sentiment classification (positive and negative) on Shopee reviews, as well as to statistically test the significance of their differences using One-Way ANOVA. A total of 400,498 reviews were collected via web scraping, preprocessed through text normalization, tokenization, and Indonesian language stemming, and then feature-extracted using TF-IDF and Count Vectorizer. Evaluation results show that SVM achieved an accuracy of 91.77%, precision of 91.49%, recall of 91.77%, and F1-Score of 91.56%, while RF achieved an accuracy of 90.07%, precision of 91.68%, recall of 90.07%, and F1-Score of 90.55%. ANOVA confirmed that the performance difference between the two algorithms is statistically significant (p-value = 0.0007) with a large effect size (η² = 0.1815). Therefore, SVM is recommended as a more optimal and consistent algorithm for automated sentiment analysis of Indonesian e-commerce reviews, while also providing a replicable methodological framework for similar future research.

In the Independent Curriculum implemented in schools starting the 2024/2025 academic year, there are Learning Outcomes (CP) that read "Students are able to modify/deconstruct literary works for creative economic purposes" and "Students are able to translate one text into another for creative economic purposes". In reality, in schools, there are still few teachers who connect literary works with economic issues, many teachers are still unfamiliar with the concept of translation, not many teachers have participated in translation training, and there is no guidebook for translating literary texts into non-literary texts or vice versa. This also applies to high school Indonesian Language teachers in Rembang Regency. Combining these two Learning Outcomes and connecting them to conditions in society, this community service conducted training on translating literary works into advertising texts for high school Indonesian Language teachers in Rembang Regency. The training was carried out with the first stage providing material on translation and advertising and the second stage providing mentoring to teachers to practice translating literary works into advertising.

The evaluation of Indonesian language instruction at the junior secondary level remains predominantly oriented toward lower-order thinking skills, thereby constraining the advancement of students’Higher Order Thinking Skills (HOTS). This situation necessitates the development of comprehensive assessment tools that are coherently aligned with the Merdeka Curriculum. The present study introduces a model for constructing HOTS-oriented assessment instruments targeting procedural text writing in Phase D. The development process was systematically organized through several stages: translating learning outcomes into measurable indicators, preparing assessment blueprints, creating item cards, formulating scoring rubrics for attitudes, knowledge, and skills, and finally analyzing and interpreting the assessment data. These instruments were specifically designed to capture students’ analytical, evaluative, and creative abilities in producing procedural texts that are logical, coherent, and effective. Findings demonstrate that the instruments provide an objective and holistic representation of students’ competency attainment. In summary, the proposed HOTS-based assessment model for procedural text writing is practical, methodical, and contextually relevant, serving as a valuable framework for evaluating Indonesian language learning in accordance with the Merdeka Curriculum principles.

The development of social media platforms like TikTok has created new spaces for digital economic activities, including the practive of thrifting, which has now become a trend among the public. However, government policies that block these activities have sparked various public reactions. This study aims to analyze public sentiment regarding the issue of thrifting bans on the TikTok platform using the Bidirectional Long Short-Term Memory (Bi-LSTM) method. This method was chosen because it can understand text context from both directions, allowing it to capture deeper semantic meaning. The dataset consist of 4,000 TikTok user comments collected through a crawling process. The research stages include data preprocessing, sentiment labeling, splitting training and test data, training the Bi-LSTM model, and evaluating performance using accuracy, precision, recall, and F1-score metrics. The research results show that the Bi-LSTM model achieved an accuracy of 86.15%, with stable classification performance and minimal error rate. These findings indicate that Bi-LSTM is effective for sentiment analysis of public opinions on Indonesian language social media, particularly on context specific policy issues. Further development can be carried out by adding pre-trained embeddings or attention mechanisms to improve the model’s performance.

This research was conducted to assess the effectiveness of using the Problem Based Learning (PBL) approach in teaching poetry writing in Indonesian language classes. This method was applied to assess the extent of students' mastery of the material and their response to problem-based learning. Based on the results of the questionnaire distributed, it was found that materials such as procedural texts, expository texts, negotiation texts, poetry, drama, and novels are materials that often use the PBL model. The results show that around 75%–80% of students understand learning with the PBL approach and show active and enthusiastic responses during the learning process. However, the implementation of PBL faces a number of obstacles, including limited time allocation and the level of readiness of students in digesting complex problems. Thus, periodic assessment and adaptation of the learning approach are key to optimising the effectiveness of this method.

Learning Indonesian language and literature in elementary schools plays an important role in shaping students' character through the integration of literary works based on local culture.

The research method used is a literature review by analyzing references in the form of scientific articles, textbooks, Lampung poetry texts, and previous research results related to character education, regional literature, and local wisdom-based learning. The results of the study indicate that Lampung poetry is effective as a literary learning medium to instill character values, especially those in line with the dimensions of the Pancasila Student Profile, namely faith and piety, mutual cooperation, creativity, and global diversity. Practical implementation can be done through literary appreciation activities, reflective discussions on cultural values, and assignments to write poetry based on students' local experiences. The conclusion of this study confirms that systematically integrating Lampung poetry into Indonesian language learning has significant potential to strengthen students' character education while preserving local culture amidst the challenges of globalization.  

This study aims to describe strategies for Indonesian language development through the use of Instagram, particularly the Story feature, as a medium for introducing Indonesian lexical equivalents. The study is grounded in the increasing use of foreign terms and code-mixing on social media, highlighting the need for language cultivation efforts that align with digital communication habits. A descriptive qualitative method was employed, with data collected from polls, question box responses, and user interaction metrics from the Instagram account @katasetara_. The findings indicate that respondents’ understanding of Indonesian lexical equivalents remains relatively low, as shown by the high percentage of incorrect answers for terms such as caption (57%), typo (56%), and headset (52%). By providing explanations in feed posts, the @katasetara_ account serves as an informative and engaging medium for language cultivation. This study concludes that Instagram holds strong potential as an effective platform for linguistic education when combined with interactive strategies and adherence to standard Indonesian language norms.

This study aims to explain the level of student interest and various aspects that influence their interest in reading poetry among students of the Department of Indonesian Language and Literature Education, Lambung Mangkurat University (ULM) class of 2024. The research focuses on how students interpret poetry, factors that encourage and inhibit reading interest, and the role of the academic environment in shaping literary appreciation, especially poetry. This study uses a descriptive qualitative approach through interviews and documentation to gain an in-depth understanding of students' experiences, views, and habits in reading poetry. The results show that students' interest in poetry is in the moderate category. Some students consider poetry to be beautiful and meaningful works, thus helping them to reflect on themselves and increase their interest in reading. However, others find it difficult to understand the implied meaning in poetry and consider poetry a complicated and less interesting genre. Factors that encourage interest in reading poetry include the active role of lecturers in presenting interesting poetry material, campus literary activities such as poetry readings and competitions, and the existence of student communities that focus on writing and literary appreciation. Meanwhile, obstacles found include limited literacy facilities such as reading rooms and poetry book collections, low student personal motivation, and the dominance of digital media which is more practical and entertaining than printed literary works. This research emphasizes the importance of creative learning strategies and support for campus activities to revitalize the culture of reading poetry so that literary appreciation can develop more optimally.

The Indonesian language holds a strategic role as a unifying national language as well as the medium of instruction in education. However, this role has not been fully internalized within indigenous communities such as the Baduy Dalam tribe, which is known for its strong adherence to tradition and the use of the Baduy dialect of Sundanese in daily life. This study aims to reveal the role of the Indonesian language in communication and education within the Baduy Dalam community and to analyze how the national language is adopted amidst the strong local culture. This research employs a qualitative method with data collection techniques including in-depth interviews, participatory observation, and document studies conducted within the Baduy Dalam community in Lebak Regency, Banten. The results indicate that the Indonesian language is beginning to be used in educational contexts, especially in formal schools around the Baduy area, although its use remains limited in everyday interactions among community members. Proficiency and understanding of Indonesian are more dominant among the younger generation who receive formal education. The social implications of these findings include the opening of access to broader information and knowledge for the Baduy Dalam people, but also present challenges in preserving local language and cultural values. This study recommends educational approaches based on local wisdom to ensure that the role of the Indonesian language progresses in harmony with the preservation of the Baduy Dalam cultural identity.

This study aims to analyze the use of Instagram as a medium for language development in the correct use of the preposition "di" according to the guidelines of Ejaan yang Disempurnakan (EYD) edition V. Although the Indonesian language has clear writing rules, inaccuracies in the use of the preposition "di" are still frequently found in both print and digital media. One of the contributing factors is the low level of public understanding of these rules. Therefore, language development through Instagram is considered an effective way to raise awareness and improve understanding among the public. This research employs a descriptive qualitative approach, collecting data through Instagram’s polling feature, which allows the researcher to measure audience understanding of the correct usage of "di". The results show an increase in audience comprehension after receiving explanations regarding the correct usage, although many respondents still showed inaccuracies in the use of "di". Therefore, a broader and more sustained language development effort via social media is needed to enhance public awareness of correct prepositional writing. This research is expected to serve as a foundation for the development of more interactive and practical language development strategies, especially in the context of social media. Keywords:

Student learning outcomes in cycle I reached an average value of 70% with incomplete criteria, but increased in cycle II to 92% with complete criteria. In addition to improving learning abilities, students also feel more enthusiastic and active in participating in learning by implementing the Cooperative Integrated Reading and Composition model. It can be concluded that the implementation of the Cooperative Integrated Reading and Composition (CIRC) model can improve the reading comprehension skills of fourth-grade elementary school students.

One of the factors that determine the success of a character-based language learning process is the interaction between teachers and students. Polite language from students can show that they have the expected character, in addition to showing that teachers have helped students behave with polite language. Classes often do not meet expectations. Many students are still unable to pronounce good words. In the last two decades, there has been a significant decline in the implementation of polite language originating from Brebes Regency. Children believe that using impolite language is acceptable to their friends and following trends in their environment because of the abundance of impolite language in society. This causes people to use Indonesian less. The purpose of this study is to determine the politeness of Indonesian language students in interacting with teachers in grade IV SDN 1 Karangdempel. This study uses a qualitative research type. The approach used in this study is qualitative research with a descriptive approach. The location of this research is SDN 1 Karangdempel, Losari District, Brebes Regency, Central Java, Indonesia 52212. Based on research that has been done on the analysis of the form of politeness in Indonesian language in interacting with teachers in the learning process is polite. Because, in the implementation of the learning process can include several maxims including: Maxim of wisdom/wisdom, maxim of generosity, maxim of praise/appreciation, maxim of humility/simplicity, maxim of agreement/agreement, and maxim of sympathy. From several existing maxims it can be concluded that the maxim of humility/simplicity is the one most frequently found in the data of politeness in Indonesian language in class IV SDN 1 Karangdempel, Brebes Regency, because that maxim is the one that occurs most often in learning activities.
