Abstract

Aksi demonstrasi atau unjuk rasa merupakan salah satu fenomena di dunia nyata yang sering terjadi dan melibatkan berbagai kalangan, baik mahasiswa, buruh, maupun anggota suatu organisasi. Khususnya di Sumatera Barat, pada tanggal 23 dan 25 September 2019 telah terjadi demonstrasi polemik RUU di gedung DPRD Sumatera Barat yang melibatkan ribuan mahasiswa, aparat kepolisian, dan anggota DPRD Tingkat I.Pada penelitian ini dibahas model matematika aksi demonstrasi mahasiswa. Model ini merujuk pada model Richardson. Model dianalisis kestabilannya melalui analisis kestabilan titik ekuilibrium. Kestabilan titik ekuilibrium ditentukan dari nilai eigen matriks koefisien yang diperoleh. Hasil analitik dikonfirmasi dengan hasil numerik. Parameter model yang digunakan pada simulasi numerik diperoleh dari data yang diolah berdasarkan kuisioner yang diambil dari responden. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa aksi demonstrasi yang terjadi berlangsung anarkis. Hal ini sesuai dengan kenyataan yang terjadi di lapangan bahwa aksi demonstrasi yang terjadi pada kasus demonstrasi polemik RUU di gedung DPRD Sumatera Barat tanggal 25 September 2019 merupakan demonstrasi anarkis.

Abstract

Stunting remains a serious public health problem in Indonesia, especially in rural areas. Simasom Village, Padangsidimpuan Angkola Julu District, is an area vulnerable to stunting due to limited knowledge about maternal nutrition during pregnancy, economic constraints, and strong local myths that restrict nutritious food intake. This community service activity employed a health promotion approach through direct nutrition counseling for pregnant women at an integrated health post (Posyandu). The method included pre-test and post-test assessments using questionnaires to measure knowledge levels, direct counseling using leaflets, and anthropometric measurements (weight, height, Mid-Upper Arm Circumference). The activity involved nine pregnant women. The activity showed a significant increase in participants' knowledge. Pre-test results indicated 68.8% of pregnant women had poor knowledge about nutrition and stunting prevention. After the counseling, the post-test results showed a decrease to only 12.5% with poor knowledge, while 87.5% achieved a good knowledge level, indicating a 56.3% improvement. Anthropometric data revealed that most participants had normal nutritional status, although two pregnant women required further nutritional intervention based on their Mid-Upper Arm Circumference measurements. Direct nutrition counseling using leaflets is effective in significantly increasing the knowledge of pregnant women about balanced nutrition and stunting prevention. Continuous and routine educational activities at Posyandu are essential to maintain and improve maternal understanding, which is expected to lead to positive behavioral changes and contribute to stunting reduction efforts in Simasom Village.

Abstract

Online learning has become a common way to deliver instruction, particularly in hybrid educational models. However, teaching speaking skills presents unique challenges because it requires real-time interaction, pronunciation practice, and fluency development. This study investigates the challenges senior high school English teachers face when teaching speaking online, the strategies they employ, and the support they require. Using a qualitative approach, data were collected from 20 teachers through questionnaires and in-depth interviews with four of them. Thematic analysis revealed four main challenges: low student engagement, time constraints that hindered feedback on pronunciation and accuracy, limited resources for authentic speaking tasks, and technical difficulties that disrupted fluency and real-time communication. To address these issues, teachers implemented various strategies. Group discussions encouraged interaction and confidence; presentations supported fluency, vocabulary, and idea organization; role-plays helped reduce anxiety and provided opportunities to practice pronunciation in contextual settings; and debates enhanced fluency, reasoning, and spontaneous speaking. The teachers also emphasized the need for engaging teaching materials, technology training, and collaborative professional development. The study concludes that although online speaking instruction presents significant challenges, strategies combined with institutional support can foster students’ fluency, accuracy, pronunciation, vocabulary, intonation, and comprehension. It is recommended that schools provide engaging digital materials, targeted teacher training, and reliable infrastructure to enhance the effectiveness of online speaking instruction.
