Abstract

This study aims to describe the forms and functions of directive speech acts used by tutors and students in the learning process of the Package C Equivalency Program at the Learning Activity Center (SKB) in Sigi Regency. This study uses a qualitative descriptive method with a pragmatic approach. Data were obtained through observations of learning activities, interviews, and recordings of tutors' and students' utterances. The results show that the directive speech acts used include commands, requests, invitations, suggestions, persuasion, and motivation. Tutors predominantly use directive speech acts in the form of commands and invitations to direct and motivate students during learning. Meanwhile, students tend to use directive speech acts in the form of requests and suggestions, which reflect reciprocal interaction. The use of these directive speech acts serves to direct the learning process while building participatory and conducive communication in the context of non-formal education. AbstrakPenelitian ini bertujuan untuk mendeskripsikan bentuk dan fungsi tindak tutur direktif yang digunakan oleh tutor dan peserta didik dalam proses pembelajaran Program Kesetaraan Paket C di Sanggar Kegiatan Belajar (SKB) Kabupaten Sigi. Penelitian ini menggunakan metode deskriptif kualitatif dengan pendekatan pragmatik. Data diperoleh melalui observasi kegiatan pembelajaran, wawancara, serta perekaman tuturan tutor dan peserta didik. Hasil penelitian menunjukkan bahwa tindak tutur direktif yang digunakan meliputi perintah, permintaan, ajakan, saran, bujukan, dan motivasi. Tutor lebih dominan menggunakan tindak tutur direktif berupa perintah dan ajakan untuk mengarahkan dan memotivasi peserta didik selama pembelajaran. Sementara itu, peserta didik cenderung menggunakan tindak tutur direktif dalam bentuk permintaan dan saran, yang mencerminkan adanya interaksi timbal balik. Penggunaan tindak tutur direktif tersebut berfungsi untuk mengarahkan proses pembelajaran sekaligus membangun komunikasi yang partisipatif dan kondusif dalam konteks pendidikan nonformal.

Abstract

This study aims to describe the level of marine vocabulary survival of Bajo language students at SMPN 7 Menui Satap, Morowali Regency, using the Project Based Learning (PBL) method and to identify the ecological and sociolinguistic factors that influence it. This study uses an ecolinguistic approach with a descriptive quantitative design. Data were collected through a vocabulary questionnaire involving 50 students with 100 marine vocabulary items, supported by interviews and documentation. Data analysis was conducted using percentage techniques and interpretive qualitative analysis. The results show that the level of marine vocabulary survival of Bajo language reached 80.72% and is in the category of still surviving. Vocabulary directly related to daily maritime activities shows a high level of survival, while rarely used traditional vocabulary is starting to weaken and is at risk of being lost. Vocabulary survival is influenced by natural factors, such as the condition of the marine environment and the geography of coastal areas, as well as social factors, such as the livelihood of fishermen and language use within the family. Conversely, the dominance of Indonesian in schools, the influence of social media, and the weakening of intergenerational transmission are the main factors in the decline of vocabulary survival. AbstrakPenelitian ini bertujuan mendeskripsikan tingkat kebertahanan kosakata bahasa Bajo dalam bidang kelautan pada siswa SMPN 7 Menui Satap Kabupaten Morowali melalui metode Project Based Learning (PBL) serta mengidentifikasi faktor-faktor ekologis dan sosiolinguistik yang memengaruhinya. Penelitian ini menggunakan pendekatan ekolinguistik dengan desain kuantitatif deskriptif. Data dikumpulkan melalui angket kosakata yang melibatkan 50 siswa dengan 100 kosakata kelautan, didukung wawancara dan dokumentasi. Analisis data dilakukan dengan teknik persentase dan analisis kualitatif interpretatif. Hasil penelitian menunjukkan bahwa tingkat kebertahanan kosakata bahasa Bajo bidang kelautan mencapai 80,72% dan berada pada kategori masih bertahan. Kosakata yang berkaitan langsung dengan aktivitas maritim sehari-hari menunjukkan tingkat kebertahanan tinggi, sementara kosakata tradisional yang jarang digunakan mulai mengalami pelemahan dan berpotensi hilang. Kebertahanan kosakata dipengaruhi oleh faktor alam, seperti kondisi lingkungan laut dan geografis wilayah pesisir, serta faktor sosial, seperti mata pencaharian nelayan dan penggunaan bahasa dalam keluarga. Sebaliknya, dominasi bahasa Indonesia di sekolah, pengaruh media sosial, dan melemahnya transmisi antargenerasi menjadi faktor utama penurunan kebertahanan kosakata.

Abstract

This study aims to describe: (1) the level of academic stress among students, (2) the level of peer social support, and (3) to test the significance of the relationship between peer social support and academic stress experienced by students. This research employs a quantitative method with a descriptive correlational research design. The population of this study consists of 421 students from SMPN 1 Kotanopan who were registered during the July-December semester of the 2025 academic year, with a sample of 241 students selected using Stratified Random Sampling. The instruments used were the "Peer Social Support Checklist" and the "Academic Stress Checklist." Data were analyzed using descriptive techniques and Pearson's Product Moment correlation. The results of the study indicate that (1) the peer social support for students at SMPN 1 Kotanopan is at a high level, (2) academic stress among students at SMPN 1 Kotanopan is at a low level, and (3) there is a significant negative relationship between peer social support and academic stress. This study indicates that when the level of peer social support is high, academic stress among students is low.

Abstract

This study investigates the effectiveness of two Finite Impulse Response (FIR) filter designs based on the Hanning and Blackman-Harris windows for preprocessing electroencephalography (EEG) signals collected from both neurotypical individuals and those diagnosed with Autism Spectrum Disorder (ASD). EEG signals were recorded using a 16-channel setup and band-pass filtered between 0.5 and 40 Hz to isolate relevant neural activity. Subsequently, the signals were processed independently using each FIR filter type. Performance evaluation was conducted using four quantitative metrics: Mean Absolute Error (MAE), Mean Squared Error (MSE), Signal-to-Noise Ratio (SNR), and Power Spectral Density (PSD). The Hanning window filter showed MAE values ranging from 0.079 to 0.325, MSE from 0.026 to 0.177, SNR between 7.56 and 15.86 dB, and PSD values from 5.3 to 9.08 × 10⁻³. These results demonstrate good noise attenuation while preserving signal morphology. In contrast, the Blackman-Harris window produced higher MAE (0.061–0.318) and MSE (0.019–0.172) but achieved significantly greater SNR improvements (7.77–17.4 dB) and tighter control over PSD (4.904 – 8.442 × 10⁻³), indicating superior noise suppression and reduced spectral leakage. A paired t-test confirmed that differences in all four performance metrics were statistically significant (p < 0.05) across both neurotypical and ASD subject groups. Despite the Hanning filter's computational simplicity, the Blackman-Harris filter demonstrated more robust performance, making it a more suitable choice for high-fidelity EEG signal analysis in clinical diagnostics and neuroscience research.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesadaran ekologis, kemampuan literasi kreatif, dan literasi digital remaja di Desa Tambu, Kecamatan Balaesang, Kabupaten Donggala melalui pelatihan penulisan puisi ekologi yang dikemas secara menarik dengan memanfaatkan platform media sosial TikTok. Permasalahan yang mendasari kegiatan ini adalah rendahnya minat remaja terhadap isu lingkungan serta terbatasnya media ekspresi yang sesuai dengan gaya hidup digital mereka. Metode kegiatan terdiri atas tiga tahapan utama, yaitu: (1) Tahap Persiapan, yang meliputi koordinasi internal dan eksternal, penyusunan instrumen pelatihan, serta kesiapan teknis; (2) Tahap Pelaksanaan, yang mencakup sosialisasi isu ekologi, pelatihan penulisan puisi bertema lingkungan dengan pendekatan kreatif, pelatihan produksi video puisi berbasis TikTok, serta pendampingan intensif dalam produksi konten digital; dan (3) Tahap Evaluasi, dilakukan melalui pretest dan posttest, observasi, serta refleksi partisipatif. Hasil kegiatan menunjukkan peningkatan signifikan dalam tiga aspek utama. Rata-rata skor peserta meningkat dari 52,3 menjadi 82,7 dalam pemahaman isu ekologi dan sastra; dari 49,8 menjadi 85,1 dalam kemampuan menulis puisi tematik; dan dari 44,2 menjadi 84,6 dalam kemampuan memanfaatkan TikTok sebagai media edukasi. Secara kualitatif, peserta menunjukkan perubahan sikap, rasa percaya diri, serta keberanian mengekspresikan kepedulian terhadap lingkungan melalui media digital. Peserta juga berhasil menghasilkan video puisi yang dikemas kreatif dan memperoleh respon positif dari audiens di media sosial. Kegiatan ini membuktikan bahwa pendekatan berbasis sastra dan media digital mampu menjadi strategi efektif dalam meningkatkan literasi ekologis dan digital remaja. Model ini dapat direplikasi sebagai upaya edukatif berbasis komunitas yang relevan dengan kebutuhan generasi muda masa kini.

Abstract

This study aims to describe the patterns and effectiveness of directive speech acts used by students of the Visual Communication Design (DKV) Department under the Merdeka Curriculum at SMKN 2 Palu, particularly in the context of promoting their design products. The study combines qualitative analysis of directive forms (inviting, requesting, suggesting, commanding) with quantitative measurement of communication effectiveness using a Likert scale. The findings reveal that students predominantly use inviting and suggesting speech acts, while requesting and commanding occur less frequently. Based on Berlo’s SMCR model, the suggesting directive emerges as the most effective form due to its combination of politeness, clarity of intention, and persuasive power, whereas requesting shows the lowest effectiveness. Social factors such as gender, age, local dialect use, and learning environment influence students’ communication patterns. The Chi-Square test indicates a significant relationship between types of directive speech acts and their levels of effectiveness (p < 0.05). These findings highlight the need to strengthen students’ professional communication competence within the DKV learning framework, particularly in the context of the Merdeka Curriculum and Teaching Factory, to enable students to promote their design works more persuasively and in alignment with industry standards
