This study aims to optimize Indonesian language development, especially in correcting language errors in seventh-grade students through French fries as an interactive learning tool. This classroom action research was conducted in one cycle on 30 students of grade VII-E of SMP Negeri 12 Tasikmalaya in the 2025/2026 academic year. A qualitative approach with data collection techniques in the form of observation, sentence correction tests, interviews, and documentation was used in this study. The results showed that the use of French fries media with incorrect sentences in it can improve students' ability to identify and correct errors in spelling, grammar, and word choice. The percentage of completeness of sentence correction skills increased from 33.33% (pre-action) to 86.67% after the implementation of the action. This media can also increase student motivation and involvement in learning. It can be concluded that this French fries media is effective to be used as an aid in Indonesian language development that is fun and highly contextual.  

Indonesian Sign Language (BISINDO) serves as a primary communication medium for the deaf community; however, limited public understanding often creates barriers during daily interactions. This study aims to develop a real-time BISINDO word-level translation system using hand landmark extraction and temporal modeling with Long Short-Term Memory (LSTM). The system employs MediaPipe Hands to detect 21 hand landmarks per frame, which are then processed as sequential motion patterns to classify five BISINDO words: saya, terima kasih, maaf, nama, and kamu. A total of 250 gesture samples were recorded under controlled lighting conditions as the primary dataset. The processed sequences were used to train the LSTM model, which was subsequently integrated with an ESP32 microcontroller and a DFPlayer Mini module to produce direct audio output. Experimental results show that the model achieved an average accuracy of 86%, with precision and recall values ranging from 0.81 to 0.94. The confusion matrix analysis indicates that most gestures were correctly classified, although some errors occurred in gestures with similar initial motion trajectories. Integration testing demonstrated an average system latency of 3.8 seconds and an audio output success rate of 85%. These findings indicate that the proposed system is capable of translating BISINDO word-level gestures accurately, responsively, and consistently in real-time conditions. This study provides a strong foundation for the broader development of sign language translation systems, with potential enhancements in vocabulary expansion, multi-user datasets, and hardware optimization for deployment in real-world environments.

This study aims to describe the implementation of Indonesian grammar coaching through language quizzes and examine its effectiveness in improving the language skills of fifth-grade students at SDN Nyantong. The background of this study is based on the low ability of students to understand and use standard words, spelling, and punctuation in accordance with the applicable rules of Indonesian language. This condition requires more interesting, creative, and interactive learning innovations so that students are more motivated to learn grammar. The research method used is descriptive qualitative with data collection techniques through direct observation, interviews with teachers and students, and documentation of learning activities carried out in the classroom. The results showed that coaching activities through language quizzes increased students' activity, motivation, and interest in learning Indonesian. Through these activities, the learning process became more enjoyable and interactive, encouraging students to participate actively and express their opinions. Students showed a significant improvement in the correct use of standard words, spelling, and punctuation in both written and spoken contexts. However, there were still obstacles in the form of difficulties in distinguishing between standard and non-standard words and errors in the use of prepositions due to the influence of everyday language habits. Overall, language quizzes have proven to be an effective and relevant innovative learning strategy for improving Indonesian grammar skills in elementary schools.

This article analyzes language errors in essays written by high school students and published on the Mojok.co website in the March 2025 edition. It employs a descriptive qualitative approach with purposive sampling. Five essays were selected based on topic relevance and language difficulty levels appropriate for high school students. The analysis reveals language errors in four main categories: spelling, grammar, diction, and punctuation. Spelling errors are the most frequent, involving incorrect word forms that deviate from standard Indonesian spelling conventions, such as improper capitalization and the use of numerals where they are inappropriate. Grammar errors include issues in sentence structure, particularly in the incorrect placement of subjects and predicates. Diction errors often involve the use of inaccurate or informal vocabulary, while punctuation errors are evident in the misuse or misplacement of commas and periods. These findings suggest that students’ language proficiency in essay writing still requires improvement. To enhance their skills, the following recommendations are proposed: increasing students’ understanding of spelling, grammar, diction, and punctuation based on the General Guidelines for Indonesian Spelling; providing structured and continuous writing practice; incorporating technology such as spell checkers and grammar tools; and fostering an understanding of language variations, especially the differences between spoken and written language. Improving students’ writing skills is essential, as language errors can impede effective communication and undermine a writer’s credibility. This article aims to serve as a reference for both teachers and students in recognizing common writing errors and enhancing the overall quality of student essays.

The purpose of this study is to describe spelling errors in descriptive texts of grade XI students of SMA Negeri 3 Lhokseumawe. This research method is descriptive qualitative. Data were collected using documentation and note-taking techniques. Data analysis techniques were carried out through several stages, namely collecting data samples and identifying errors, classifying data based on the type of spelling errors, and describing the forms of errors found. The results of the study indicate that many students still make spelling errors, such as errors in capitalization, writing basic words, redundant words, pronouns, prepositions, abbreviations and acronyms, period errors, and comma errors. These errors are caused by students' lack of accuracy and understanding in implementing Indonesian Spelling when writing. In this case, students must be given a better understanding of Indonesian Spelling. To overcome this problem, teachers have an important role in providing more intensive learning related to the implementation of Indonesian Spelling. One effort that can be done is to provide structured writing exercises, accompanied by direct feedback on spelling errors made by students. Furthermore, the use of digital learning media, such as spelling correction apps or interactive writing platforms, can help students improve their writing skills more effectively. With the right learning strategies, it is hoped that students will be able to understand spelling rules in depth and apply them correctly in every writing activity. Furthermore, students' writing skills also need to be honed through more varied activities, such as writing competitions, daily journals, or creative writing projects that require consistent application of spelling rules. Teachers can also implement a peer review method, where students correct each other's writing, thus creating collaborative learning that can increase language awareness.

This corpus-based study explores the acquisition patterns of English modal verbs by Indonesian EFL (English as a Foreign Language) learners through a comprehensive analysis of learner language data. The study utilizes a specialized learner corpus consisting of 2.5 million words drawn from both written and spoken productions of 450 Indonesian learners, covering various proficiency levels. The research focuses on examining the frequency patterns, semantic distributions, and error types associated with modal verb usage across the learner corpus. The study employs a combination of quantitative corpus linguistic methods and qualitative error analysis to uncover developmental trends and persistent difficulties in acquiring English modals. The findings highlight a significant underuse of epistemic modality, which expresses degrees of certainty, and an overreliance on core modals like "can," "will," and "must." Additionally, learners systematically avoid more complex modal constructions that are semantically nuanced and less frequent in their linguistic output. The analysis also reveals notable cross-linguistic influences from Indonesian, particularly in the areas of politeness marking and the expression of certainty. These interference patterns suggest that Indonesian learners may transfer modal expressions from their native language, leading to specific errors in the usage of English modals. Based on the findings, the study proposes a usage-based pedagogical framework that integrates corpus-informed instruction with explicit semantic mapping of modal meanings. This framework encourages teachers to address modal verb acquisition by emphasizing frequency-based approaches, contrastive semantic analysis, and corpus-driven awareness-raising activities. The research suggests that by focusing on the form-meaning-function relationships of modals in authentic contexts, learners can better understand and produce English modals accurately and appropriately. The findings have significant implications for enhancing modal verb instruction in EFL classrooms, especially for Indonesian learners.

This study aims to identify the phonological differences shown by two three-year-old boys, namely Galfin Yasasi Habbika and Muhammad Arkhan Al Hafiz with different family backgrounds in Pangalengan, Bandung, and it analyzed the environmental factors and parental roles that contribute to variations in their phonological acquisition. This Study uses descriptive qualitative method with the data were conducted through video documentation of natural interactions and interviews with the parents of both children. The data collected were 18 utterances from each child which were then analyzed based on phonological aspects to identify error patterns, compensation strategies, and articulation skills. The findings showed that the two children has different phonological development patterns with Galfin showing more conservative phonological strategy by maintaining the original word structure, and people interaction environment from digital medias showing good phonological awarenees in Indonesian language development. While Arkhan showed more active phonological reconstruction by transforming difficult words into more easly produced form with a family environment that often made direct correction to Arkhan’s phonological errors which more stable and consistent phonological structure. Their phonological development was also successfully achieve through a variety of consistent support strategies that were responsive to the child’s emotional state and learning style. The result of this study support Chomsky’s Language Acquisition Device theory, in which both children demonstrated an innate capacity for language learning while showing how environmental triggers activated and shaped this biological predisposition because the children's ability to produce complex phonological structures without explicit instruction supports the nativist perspective on language acquisition.          

This study analyzes the use of non-standard words in a thesis entitled "Effectiveness of Waste Management Based on Reduce, Reuse, Recycle (TPS 3R) Waste Disposal Sites at TPS Jokotole, Barurambat Timur Village, Pademawu District, Pamekasan Regency". The use of language is an essential thing in communicating, both orally and in writing to convey messages and information so that they are conveyed effectively. However, language errors are often found, especially the use of non-standard words, even by someone who has a deep understanding of Indonesian language rules.
