Abstract

Persepsi masyarakat terhadap obat kimia dan tradisional di Indonesia memiliki pengaruh signifikan terhadap pilihan pengobatan serta tingkat kepatuhan pasien dalam menjalani terapi. Kedua jenis obat ini, meskipun digunakan secara luas, kerap kali dipandang berbeda oleh masyarakat berdasarkan berbagai faktor seperti budaya, nilai-nilai kepercayaan, dan pengalaman personal dalam penggunaannya. Dalam konteks modern yang ditandai dengan berkembangnya teknologi digital, media sosial telah menjadi ruang publik yang penting bagi masyarakat untuk mengekspresikan opini, berbagi pengalaman, dan membentuk narasi kolektif tentang obat-obatan. Artikel ini bertujuan untuk menganalisis persepsi masyarakat Indonesia terhadap obat kimia dan obat tradisional melalui pendekatan interdisipliner yang menggabungkan analisis linguistik dan pemrosesan bahasa alami (Natural Language Processing/NLP). Data dikumpulkan dari platform media sosial seperti Twitter serta forum-forum kesehatan daring selama periode Januari hingga Maret 2024, menghasilkan lebih dari 50.000 unggahan dan komentar. Proses analisis mencakup pra-pemrosesan teks, analisis sentimen menggunakan model IndoBERT, topic modeling dengan BERTopic, dan analisis linguistik untuk menggali kedalaman makna bahasa yang digunakan masyarakat. Hasil penelitian menunjukkan bahwa obat tradisional lebih sering diasosiasikan dengan persepsi positif, terutama terkait sifatnya yang dianggap alami dan aman. Sebaliknya, obat kimia sering dipandang negatif, terutama karena isu efek samping dan ketergantungan. Temuan ini memberikan wawasan penting dalam menyusun strategi komunikasi kesehatan dan edukasi masyarakat yang lebih adaptif terhadap persepsi dan pola bahasa publik di Indonesia.

Abstract

Reinforcement bars, or rebar, face length limitations, prompting the need for connection methods in construction. Techniques like overlapping splicing, welding, and mechanical clamping address this. This research investigates flexural performance in reinforced concrete beams, focusing on tensile reinforcement splice methods—overlapping and mechanical clamping with a clamp connection. Key aspects such as flexural moment, deflection, and crack patterns are evaluated through laboratory testing using a two-point loading method. Findings show that beams with overlapping splices outperform those with mechanical clamping, with nominal moments of 33.5 kNm and 32.31 kNm, and deflections of 69.37 mm and 49.02 mm, respectively. Crack patterns in both samples indicate failure at one-third of the beam span due to reinforcement splices at the midpoint, enhancing cross-sectional area. In conclusion, this research underscores the superior performance of overlapping splices in terms of nominal moment and deflection, offering valuable insights for optimizing reinforced concrete element performance in structural engineering.

Abstract

Sastra dan sejarah di Kabupaten Gowa merupakan dua entitas yang saling berkelindan dalam membentuk konstruksi identitas budaya masyarakat. Berbagai bentuk teks tradisional seperti lontaraq, kelong, tuturan lisan, hingga legenda-lagenda lokal tidak hanya menjadi ekspresi artistik, tetapi juga arsip historis yang merekam perkembangan sosial, politik, dan budaya Gowa dari masa kejayaan Kerajaan Gowa–Tallo hingga era modern. Penelitian ini bertujuan mendeskripsikan bagaimana identitas, nilai budaya, dan dinamika sosial masyarakat Gowa direpresentasikan melalui karya-karya sastra dan catatan sejarahnya. Metode yang digunakan adalah deskriptif kualitatif melalui analisis tekstual pada sumber sastra tradisional, dokumen lontaraq, serta literatur sejarah. Hasil penelitian menunjukkan bahwa sastra berfungsi sebagai mekanisme penguatan identitas kolektif, penjaga nilai budaya siri’, pacce, lempu, dan getteng, sekaligus menjadi refleksi perubahan sosial akibat modernisasi dan pergeseran budaya. Dengan demikian, sastra Gowa memainkan peran strategis dalam memahami rekam jejak sejarah dan dinamika sosial masyarakat setempat. Literature and history in Gowa Regency are two interrelated entities that collectively shape the cultural identity of its society. Various forms of traditional texts, such as lontaraq, kelong, oral narratives, and local legends, function not only as artistic expressions but also as historical archives documenting the social, political, and cultural development of Gowa from the era of the Gowa–Tallo Kingdom to the modern period. This study aims to describe how identity, cultural values, and social dynamics of Gowa’s society are represented through its literary works and historical records. The research employs a descriptive qualitative method through textual analysis of traditional literary sources, lontaraq manuscripts, and historical literature. The findings reveal that literature serves as a mechanism for strengthening collective identity, preserving cultural values such as siri’, pacce, lempu, and getteng, as well as reflecting social changes influenced by modernization and cultural shifts. Thus, Gowa’s literary tradition plays a strategic role in understanding the historical traces and social dynamics of the local community.

Abstract

This study aims to examine the relationship between literature, ecology, and Indonesian culture through an ecocritical approach. Literature is understood not only as an aesthetic work but also as a representation of the relationship between humans, nature, and their social environment. The ecological approach to literature views literary texts as reflections of ecological awareness and cultural values that shape how humans perceive and treat nature. This research employs a qualitative descriptive method using a literature review technique. The data were obtained from Indonesian literary works with ecological themes, such as Orang-Orang Proyek by Ahmad Tohari and Nyanyian Rimba by Triyanto Triwikromo, as well as relevant references on literary ecology and Indonesian cultural studies. The analysis focuses on identifying the representation of ecological values in the literary texts, emphasizing the interconnections among humans, culture, and the environment. The results indicate that Indonesian literary works convey ecological values such as harmony between humans and nature, local wisdom, mutual cooperation (gotong royong), simplicity, and environmental responsibility. Literature functions as a cultural archive that records the ecological worldview of traditional communities while also serving as a medium for reflection and critique of environmental crises caused by modernization. Furthermore, literature holds significant potential in fostering ecological awareness and sustainability ethics through the promotion of cultural values. Thus, literary ecology plays a vital role in understanding and revitalizing cultural practices to be more in harmony with nature and in strengthening the function of literature as a medium for cultivating ecological consciousness among students at MA Arifah Gowa.

Abstract

This research focuses on the development of speech recognition technology for the Mandar language, a regional language in Indonesia with limited digital resources. The main challenge lies in the lack of local datasets and the minimal representation of the Mandar language in existing multilingual speech recognition models. This study aims to enhance the performance of Automatic Speech Recognition (ASR) systems by fine-tuning the Whisper model using a Mandar-specific dataset. The dataset consists of 1,000 audio recordings with various dialects and recording qualities, which underwent preprocessing steps such as segmentation, normalization, and data augmentation. Fine-tuning was conducted using supervised learning methods with hyperparameter optimization, resulting in a reduction of Word Error Rate (WER) from 73.7% in the pretrained model to 37.4% after fine-tuning, and an increase in accuracy from 26.3% to 62.6%. The optimized model was also compared with other ASR models, such as DeepSpeech and wav2vec 2.0, demonstrating superior performance in terms of accuracy and time efficiency. Further analysis revealed that recording quality and dialect variations significantly impacted model performance, with high-quality recordings and standard dialects yielding the best results. The model was implemented as a web application prototype, enabling efficient and near real-time transcription of Mandar speech. This research not only contributes to the development of ASR technology for low-resource languages but also opens new opportunities for preserving and utilizing the Mandar language through digital technology. For future improvements, larger datasets, more advanced augmentation techniques, and the exploration of additional language model integration are recommended.

Kesimpulan penelitian ini menegaskan bahwa pembelajaran sejarah berbasis kearifan lokal merupakan strategi pedagogis yang efektif untuk mengembangkan kesadaran sejarah, karakter, dan identitas budaya siswa, sekaligus memperkaya praktik pembelajaran sejarah di sekolah. History learning in schools still tends to focus on the memorization of facts, which limits its ability to foster historical awareness and students’ connection to their surrounding socio-cultural realities. This study aims to analyze the effectiveness of innovative history learning based on local wisdom in enhancing students’ historical awareness. The research employed a qualitative approach with a case study design, involving students and history teachers in secondary schools in South Sulawesi. Data were collected through observations, in-depth interviews, documentation, and student reflections, and analyzed using data reduction, data display, and thematic conclusion drawing. The findings indicate that the integration of local wisdom into history learning improves students’ historical understanding, encourages active participation in learning, and strengthens students’ emotional connection to history and local cultural identity. Learning becomes more contextual, meaningful, and relevant to students’ lived experiences. This study concludes that local wisdom–based history learning is an effective pedagogical strategy for developing students’ historical awareness, character, and cultural identity, while also enriching history teaching practices in schools.

Abstract

Numeracy literacy is an essential competency that needs to be developed starting at the primary school level through instruction and assessment capable of measuring reasoning skills and the ability to solve contextual problems. However, teachers still face challenges in designing numeracy literacy assessments that are integrated with thematic learning. This community service activity aimed to enhance teachers' knowledge and skills in developing numeracy literacy assessments aligned with the characteristics of thematic learning. The activity was conducted at UPT SD Negeri 20 Bangkala Barat, Jeneponto Regency, involving 11 teachers as participants. A participatory training method was employed, comprising four stages: preparation, training implementation, workshops and mentoring, and evaluation and reflection. Evaluation was carried out using pre-tests and post-tests, assessments of the assessment products created by participants, and participant response questionnaires. The results showed an increase in the participants' average score from 61.82 in the pre-test to 87.36 in the post-test. The resulting assessment products achieved an average score of 3.60 (categorized as "very good"), while participant response to the activity implementation averaged 96.9% (also categorized as "very good"). In addition to improving conceptual understanding, this activity produced examples of numeracy literacy assessment tools ready for classroom implementation. The program demonstrates that training combined with workshops and mentoring is effective in enhancing teachers' competence in designing numeracy literacy assessments. Similar activities should be conducted sustainably and expanded to more schools to generate a broader impact on improving the quality of learning in primary schools.
