Abstract

Students often have difficulty in understanding chemistry lessons, especially Colligative Properties. Teachers should have systematic learning plans so that students understand the content of learning well. Hypothetical Learning Trajectory (HLT) is effective to be used in the learning process because it becomes an idea in designing detailed learning paths. Besides that, learning outcomes can be achieved well and optimally. This study uses qualitative and quantitative approaches. Data processing is carried out based on four assessment criteria. First, student responses that appear based on response predictions, second, student ability test scores, third, analysis of learning activities, and finally science process skills (SPS). The results showed that the didactic presented by the teacher as a student learning path was good enough. Only 12% of student responses are beyond predictions. Furthermore, student SPS through the use of HLT shows that classification and communication skills have a high value, respectively 82% and 81%. Meanwhile, based on Piaget's approach, students' conceptual abilities are better (56%), compared to other abilities. Therefore, the application of HLT to the material of colligative properties towards students is very good.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi jenis ektoparasit dan menghitung prevalensi serta intensitas infeksi pada udang vaname (Litopenaeus vannamei) di tambak Desa Alue Naga dan Desa Deah Raya, Banda Aceh. Sampel diambil dari dua lokasi dengan total 28 ekor udang yang diperiksa. Zoothamnium sp., Vorticella sp., dan Epistylis sp. adalah ektoparasit yang ditemukan dengan prevalensi tertinggi sebesar 100% untuk Vorticella sp. dan Epistylis sp. di Desa Alue Naga. Intensitas infeksi tertinggi tercatat pada Vorticella sp. di bagian ekor dengan rata-rata 443 individu per ekor. Kualitas air, termasuk suhu, pH, dan salinitas, berada dalam batas normal dengan suhu 32°C, pH 6,25-6,86, dan salinitas 22-42 ppt, mendukung kondisi budidaya udang vaname. Hasil penelitian ini menunjukkan perlunya pengelolaan penyakit yang efektif dalam budidaya udang vaname.

Abstract

One aspect of process science skills that learners need to have is the ability to interpret. The ability to interpret graphs in students is currently considered difficult and still belongs to the very low category. This study aims to analyze the relationship between mathematical understanding and the learning styles of students in terms of their ability to interpret graphs. This type of research is descriptive-quantitative. The research sample consisted of class XI students at SMA Negeri 4 Takengon, which amounted to 67 students. The research data was collected using learning style-type questionnaires, multiple-choice questions on linear program material, and reaction rate material. The ability to interpret the graphs of students at SMA Negeri 4 Takengon is on the "medium" criterion, while the students' mathematical understanding is on the "very high" criterion. Students with visual learning style types are more dominant and have an average score of mathematical understanding and the ability to interpret graphs higher than students with auditorial and kinesthetic learning styles. The result of the correlation coefficient r = 0.912 shows a significant positive relationship between mathematical understanding and the ability to interpret graphs with a "high" and unidirectional interpretation

Abstract

Hand hygiene is a simple thing that is often overlooked, especially in schools located in coastal areas with limited sanitation facilities. This community service activity aims to introduce innovations in the production of liquid hand soap and sea salt-based paper soap as an effort to improve health and empower the local economy. The implementation methods include education, demonstrations of production, and direct training for community partners. This service was carried out at Banda Aceh State Elementary School 61 from July to September 2025. The training produced 30 L of liquid soap and 1000 sheets of paper soap; by the end of the session, 75% of participants completed all production steps correctly (checklist). Entrepreneurial outputs included a student–teacher sanitation team and two product mock-ups with basic costing (estimated unit cost Rp 12.000 per 500 mL vs market price Rp 18.000). These results indicate technical feasibility and school-based micro-enterprise potential. For sustainability, the school committed to monthly in-house production led by the sanitation team and integrating the activity into UKS to secure continuous supply and ongoing skill transfer.

Abstract

Abstract: Marine macroalgae are known for their rich bioactive compounds, offering various pharmacological benefits. This research was conducted to analyze the phytochemical composition and metabolite profiles of Ulva lactuca, a marine macroalgae, along the coastal region of Banda Aceh, Indonesia. The research methodology encompassed three primary phases: assessment of antioxidant scavenging activity, determination of phytochemical composition, and in vivo metabolite profiling. The extract exhibited notable antioxidant activity, evidenced by its 47.22% inhibition rate. Spectral analysis via FTIR revealed prominent peaks at 1019 cm−1, 1654 cm−1, and 3352 cm−1, indicative of the presence of ethers, carbonyls, and hydroxyl groups, respectively. GC-MS analysis, coupled with a literature review, identified a total of 30 phytochemical compounds within Ulva lactuca, several of which possess significant bioactive properties with potential applications as antibacterial agents in both human and animal contexts. Consequently, Ulva lactuca demonstrates promising prospects as a source of antibacterial agents. The implications of this study suggest that Ulva lactuca could be developed as a natural alternative for antibacterial treatments, potentially reducing dependence on synthetic antibiotics in both healthcare and aquaculture industries. Abstrak: Makroalga dikenal karena kandungan senyawa bioaktifnya yang kaya, yang menawarkan berbagai manfaat farmakologis. Penelitian ini dilakukan untuk menganalisis komposisi fitokimia dan profil metabolit dari Ulva lactuca di sepanjang wilayah pesisir Banda Aceh, Indonesia. Metodologi penelitian mencakup tiga fase utama: penilaian aktivitas antioksidan, penentuan komposisi fitokimia, dan profil metabolit in vivo. Ekstrak menunjukkan aktivitas antioksidan yang signifikan, dibuktikan dengan tingkat inhibisi sebesar 47,22%. Analisis spektral menggunakan FTIR mengungkapkan puncak pada 1019 cm−1, 1654 cm−1, dan 3352 cm−1, yang menunjukkan adanya gugus eter, karbonil, dan hidroksi. Analisis GC-MS, yang dipadukan dengan tinjauan literatur, mengidentifikasi total 30 senyawa fitokimia dalam Ulva lactuca, beberapa di antaranya memiliki sifat bioaktif signifikan dengan potensi aplikasi sebagai agen antibakteri dalam konteks manusia dan hewan. Dengan demikian, Ulva lactuca menunjukkan prospek yang menjanjikan sebagai sumber agen antibakteri. Implikasi dari penelitian ini menunjukkan bahwa Ulva lactuca dapat dikembangkan sebagai alternatif alami untuk pengobatan antibakteri, yang berpotensi mengurangi ketergantungan pada antibiotik sintetis dalam industri kesehatan dan akuakultur.
