Abstract

Motivation for healthy living is an effort to achieve optimal physical and mental health levels. One of the factors of healthy living behavior is the existence of healthy living motivation in a person. Students who have been equipped or have healthy living motivation will consistently carry out a healthy lifestyle. This condition is because the student is already motivated to maintain their health. However, if the student is not motivated to implement a healthy lifestyle, it will not be easy to maintain a healthy lifestyle consistently. The research method used in this study was an online search or literature study, which obtained information and data by analyzing valid research articles from both national and international sources. The study results showed that five articles examined the influence of motivation and healthy living behavior. Thus, motivation and healthy living behavior have a significant influence. As explained, the tendency to act is based on the motive to achieve a high degree of healthy living, and that person must have high motivation. The results of this study are expected to provide insight for other researchers to conduct similar research.

Abstract

Kesehatan reproduksi bagi wanita merupakan hal penting untuk dipelajari. Oleh sebab itu, penting sekali bagi orang tua untuk memainkan perannya dalam memberikan pengetahuan dasar mengenai kesehatan reproduksi bagi mereka. Setelah di berikan pengetahuan dasar mengenai kesehatan reproduksi oleh orang tua, pada dasar nya para remaja yang masih duduk di bangku sekolah juga diberikan bekal dalam menjaga kesehatan reproduksi nya melalui pembelajaran, khususnya dalam pembelajaran biologi di sekolah. Tingkat pemahaman peserta didik yang didapatkan dari sekolah merupakan aspek penting dalam memengaruhi tindakan peserta didik untuk menjaga kesehatan reproduksinya. Metode penelitian yang digunakan dalam penelitian ini dengan pencarian daring atau studi literatur. Berdasarkan hasil literatur review dapat disimpulkan bahwat tingkat pengetahuan dan sikap peserta didik megenai sistem reproduksi tergolong baik. Tingkat pengetahuan berpengaruh positif terhadap kesehatan reproduksi. Peserta didik yang memilki pengetahuan yang tinggi akan memiliki sejumlah persiapan untuk menjaga kesehatan reproduksinya. Pengetahuan yang tinggi membuat peserta didik mengetahui hal-hal apa saja yang penting untuk dijaga dan dirawat.

Abstract

Penelitian ini bertujuan untuk mengetahui informasi tentang profil keterampilan komunikasi dan kolaborasi peserta didik dalam pembelajaran IPA pada materi pengenalan sel di kelas VIII SMP Negeri 8 Medan berdasarkan indikator dari keterampilan komunikasi dan kolaborasi, serta hasil observasi dalam pembelajaran dan hasil wawancara peserta didik. Penelitian ini dilaksanakan pada bulan April-Agustus 2024 di SMP Negeri 8 Medan. Penelitian ini termasuk ke dalam penelitian kualitatif. Penentuan subjek menggunakan teknik pusposive sampling. Subjek terdiri atas 1 orang guru IPA kelas VIII dan 4 orang peserta didik kelas VIII. Data dikumpulkan melalui wawancara mendalam kepada subjek penelitian dan juga observasi langsung terkait keterampilan komunikasi dan kolaborasi peserta didik dalam pembelajaran. Hasil penelitian menunjukkan bahwa, keterampilan komunikasi dan kolaborasi peserta didik pada materi pengenalan sel menunjukkan kemampuan yang beragam. Pada tahap observasi menunjukkan bahwa hanya sebagian siswa yang aktif dalam menyampaikan pendapat saat diskusi kelas, yaitu dari 30 peserta didik hanya sebanyak 12 orang siswa atau sebesar 40% yang aktif memberikan pendapat, sementara sebagian lainnya hanya diam tidak memberikan pendapat dan belum mampu menjelaskan materi dengan baik. Meskipun antusiasme siswa tinggi, hanya sedikit yang mampu mendiskusikan kembali materi secara efektif. Namun, mereka menunjukkan komunikasi yang baik dengan bertanya dan menjawab pertanyaan dari guru dan teman sekelas. Selain itu, keterampilan kolaborasi siswa terlihat dari partisipasi aktif dalam diskusi dan kerja kelompok, dimana mereka dapat bekerja sama menyelesaikan tugas dengan tepat waktu dan bertanggung jawab.

Abstract

This study aimed to investigate the effect of problem-based learning on students' science literacy skills in the excretory system material for grade 11 science students at Madrasah Aliyah Negeri Binjai. This research was a quasi-experimental study using a pretest-posttest nonequivalent control group design. The population of this study was all grade 11 science students at Madrasah Aliyah Negeri Binjai in the 2023/2024 academic year. Cluster sampling was used to obtain two classes as samples, namely the experimental class (XI MIA 2) and the control class (XI MIA 5). Data was collected using a science literacy test instrument consisting of 20 multiple-choice questions, developed based on the Programme for International Student Assessment (PISA) framework, which measures three science literacy competencies: explaining phenomena scientifically, evaluating and designing scientific investigations, and interpreting data and evidence scientifically. The results showed that the average post-test score of the experimental class (using PBL) was higher (81.67) compared to the control class (61.06). The Independent Sample T-test showed a significant difference between the two groups, so the null hypothesis was rejected and the alternative hypothesis was accepted. Based on these results, it can be concluded that PBL has a positive effect on improving students' science literacy skills in the excretory system material.

Abstract

This research employed the experimental method with descriptive data analysis. It aimed to isolate and identify sponge symbiont bacteria with antibacterial potential against Multi-Drug Resistance Organisms (MDRO) with the 16S rRNA gene marker. Based on the study results, two sponges were obtained, namely Clathrina sp and Agelas sp, each having 11 and 7 isolates of symbiont bacteria, respectively. Based on the antibacterial activity test results, out of 18 isolates of symbiont bacteria, only 4 had antibacterial potential against MDRO (Klebsiella pneumoniae ESBL, Pseudomonas aeruginosa ESBL, or Staphylococcus lugdunensis MRSA) with inhibition zones of 9.3 mm, 8.3 mm, and 8.1 mm, respectively. The results of bacterial identification using the 16S rRNA gene sequence isolate S1I3, S1I9, and A1I3 belong to the Bacillus cereus and Bacillus paramycoides types. This research is expected to provide important information about sponge symbiont bacteria with antibacterial potential against MDRO.
