Abstract

PVA/EDK (Kirinyuh/Eupatorium odoratum Leaves) composite hydrogel has been successfully developed using the freeze-thaw method. The precursor solution was prepared by dissolving PVA with a concentration of 12 wt% in water. Kirinyuh leaf extract solution (10 wt%) was then added to the precursor with a ratio of 10:0, 10:1, 10:2, and 10:3. The composite hydrogel was then fabricated using the freeze-thaw method and then the characteristics of the swelling degree and density were investigated. The purpose of this study was to explore the swelling degree of the Polyvinyl Alcohol (PVA) Composite hydrogel loaded with Kirinyuh Leaf Extract (Eupatorium odoratum). The research method used in this paper is a quantitative approach. The results showed that the density of the resulting hydrogel decreased with the addition of EDK mass, while the swelling degree increased with the increase in EDK mass. PVA hydrogel has an expansion degree of (187.05±7.36) %, while the expansion degree of composite hydrogel for PVA:EDK ratio (10:1), (10:2), and (10:3) is (209.60±30.90) %, (219.73±13.72) %, and (231.11±15.03) %. These results indicate that the degree of expansion of the PVA/EDK hydrogel produced has met the requirements for use as a wound dressing. However, for further development, further tests are needed such as tensile tests, porosity tests, morphology tests and antibacterial tests of the hydrogel for further applications.

Abstract

The current implementation of the Merdeka Curriculum is significantly different from previous curricula. The goal of the Merdeka Curriculum is to focus learning more on achieving understanding of knowledge. Regardless of how frequently learning occurs, the essence is that students must grasp physical and mathematical concepts. Therefore, this study aims to describe students' misconceptions about Newton's Laws. Newton's Laws are foundational concepts in studying dynamics of motion in Phase F. The sample for this study consists of 10 Phase F students from a private school in East Nusa Tenggara, who were given a three-tier diagnostic test. The method used is a survey method. The results indicate that overall, for all Newton's Laws concepts, all students exhibited misconceptions. Many students had misconceptions about Newton's first law as well as concepts of deceleration and friction, with a prevalence of 40%.

Abstract

Karya tulis ilmiah merupakan salah satu aspek penting dalam dunia pendidikan terlebih dalam penentuan kelulusan di tingkat sekolah menengah. Akan tetapi pemahaman siswa akan karya tulis ilimiah masih sangat rendah. Tujuan kegiatan pengabdian ini adalah untuk dapat menjadi solusi dalam meningkatkan pemahaman siswa terkait karya tulis ilmiah dan pelatihan tentang cara menentukan permasalahan dari suatu topik dan menuliskannya dalam bentuk suatu karya ilmiah dengan menggunakan sistematika penulisan yang benar. Metode yang digunakan dalam pengabdian ini adalah Participatory Rural Appraisal (PRA), yang melibatkan peserta secara aktif dalam mengumpulkan dan menganalisis informasi. Pelatihan diberikan melalui ceramah, diskusi, dan tanya jawab yang disampaikan oleh tim pengabdian dari Prodi Pendidikan Fisika Unipa pada bulan Maret - April 2024 dengan diikuti oleh 25 siswa. Hasil pengabdian ini menunjukkan bahwa secara keseluruhan pelaksanaan kegiatan pengabdian masyarakat ini berjalan sesuai dengan yang diharapkan. Hal ini dapat dilihat dari antusisme dan peningkatan pemahaman tentang penulisan karya ilmiah yang lebih baik dari sebelumnya.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya literasi digital peserta didik. Penelitian ini bertujuan untuk menganalisis kemampuan literasi digital peserta didik menggunakan E Modul berbasis Heyzine Flitbooks dalam materi pengukuran. Metode penelitian ini menggunakan kuantitatif dengan jenis penelitian Pre-experimen menggunakan desain one-group Pretest-Postest. Subjek penelitian ini adalah peserta didik kelas XA SMAS St. Petrus Kewapante yang berjumlah 8 orang. Peserta didik sebelum pembelajaran diberikan Pretest dan diakhiri pembelajaran diberikan Postest dengan materi dan bentuk soal yang sama. Dari hasil penelitian diketahui bahwa Data hasil nilai Pretest dan Postest kemudian dianalisis menggunakan uji Validitas, uji Reabilitas, uji Normalitas, uji t-berpasangan, dan perhitungan n gain dengan IBM SPSS Statistik 22. Penelitian ini menunjukkan terdapat peningkatan yang signifikan setelah diberikan pembelajaran fisika dengan e-modul berbantuan Heyzine Flipbooks. Pembelajaran dengan e-modul berbantuan Heyzine Flipbooks ini efektif meningkatkan kemampuan literasi digital peserta didik. Hal ini dibuktikan dengan perolehan nilai signifikan pada uji t berpasangan dan uji n gain berturut-turut adalah 0,02 dan 0,71. Dengan ini, pembelajaran dengan e-modul berbantuan Heyzine Flipbooks dapat dijadikan acuan atau bahan pertimbangan bagi guru untuk meningkatkan kemampuan literasi digital peserta didik.

Abstract

Problem-solving is one of the most essential skills in 21st-century learning which prepares students to face the increasingly complex problems of human life. The phenomenon of global warming remains a big problem that the world is facing. For this reason, students are expected to be able to practice their problem-solving skills in analyzing global warming issues through learning physics. This research aims to determine the extent of students' problem-solving skills related to the global warming phenomenon. The research used a descriptive method with a quantitative approach. This one-shot case study involved 22 phase E students of SMAS Katolik St. Gabriel Maumere. The data collection instrument included 8 question items containing four indicators of problem-solving abilities on global warming. Previously, students had to learn about the topic with the help of a problem-based electronic module. The results showed that the highest level of problem-solving skills was the indicator of implementing strategies with 87%, and the lowest percentage was in the evaluation category with 64%. The overall score of problem-solving skills was 72.25% in the high category, meaning that the application of the problem-based e-module provides positive results for students to transfer their knowledge in analyzing problems that occur in real life.
