Abstract

The application of problem-based learning model teaches students how to deal with problems and find solutions by expressing opinions and providing logical justification for real problems, so it is expected to improve students' argumentation skills. This study aims to determine the effect of problem-based learning model on students' argumentation skills on salt hydolysis material. This study was carried out in the even semester of the 2022/2023 academic year at MAN 2 Kampar, class XI IPA.Pretest-posttest Non-Equivalent Control Grub Design was the experimental design for this study, which used quasi-experimental methods. The sample consisted of XI IPA1 students as the experimental class and XI IPA2 as the control class. Data collected to measure students argumentation skills through tests and observations and analyzed using t-test and coefficient of determination test in SPSS 24. In the t-test, the Sig (2-tailed) = 0.000 outcome is more modest than 0.05, and that implies H0 is dismissed and Ha is accepted. For the determination test, the value (r2) = 0.284 is obtained, it can be concluded that the problem-based learning model affects students argumentation skills on salt hydrolysis material by 28.4%.

Abstract

The implementation of Merdeka curriculum has not long been established as the national curriculum, so many schools still lack teaching materials with limited textbooks.  This research aimed at developing STREAM (Science, Technology, Religion, Engineering, Art, and Mathematics) based Pancasila student profile strengthening project module on Chemical Bond lesson, and it was conducted with validity test by media and material experts, teacher practicality test, and student response test.  Research and Development (RnD) method was used in this research with Design and Development Research (DDR).  This research was conducted at State Senior High Schools 14 and 1 Pekanbaru.  The research findings showed that the validity scores were 82.6% by media experts with very valid category and 87.45% by material experts with very valid category.  The result of teacher practicality test showed that the mean was 93.84%, and it was on very practical category.  The last test was student response test, the result was 83.58%, and it was on very valid category.  The research findings showed that STREAM-based P5 teaching module developed was very valid, practical, and interesting for students.

Abstract

Sustainable Development Goals (SDGs) need to be implemented to create environmentally friendly chemistry learning. This can be done in an acid-base titration experiment using natural indicators of butterfly pea flowers. This research aims to produce a practicum guide for acid-base titrations using natural indicators of butterfly pea flowers that are valid and practicum. The research design uses the ADDIE research design, namely Analysis, Design, Development, Implementation, and Evaluation. The research results showed that butterfly pea flowers can be used as a natural indicator for acid-base titrations with color changes from pink (acidic condition) to blue (basic condition). The resulting learning media is a practicum guide which has a validity of 92% (very valid) and a practicality level of 88.75% (very practical). This data was analyzed using qualitative and quantitative analysis. The practicum guide developed is valid and practical to use as a practicum learning media in schools.

Abstract

Hasil belajar kimia siswa masih rendah, terlihat dari nilai ulangan yang belum tuntas atau tidak mencapai KKM yang telah ditetapkan. Hasil belajar yang rendah menunjukkan bahwa siswa mengalami kesulitan belajar. Penelitian ini bertujuan untuk mengetahui (1) pemahaman siswa terhadap materi hukum dasar kimia dan (2) faktor penyebab kesulitan belajar kimia siswa kelas X pada materi hukum dasar kimia. Metode penelitian yang digunakan adalah mixed method. Subjek pada penelitian ini adalah siswa kelas X Sekolah Menengah Atas Negeri 1 Minas. Adapun teknik pengumpulan data dalam penelitian ini adalah berupa tes, angket, observasi dan wawancara. Hasil analisis menunjukkan bahwa siswa mempunyai tingkat pemahaman materi yang rendah sebesar 37,81%. Hal ini disebabkan karena siswa kurang memahami konsep hukum dasar kimia dan tingkat numerik siswa yang masih rendah. Hasil analisis data menunjukkan bahwa faktor yang paling berpengaruh adalah faktor internal sebesar 58,62% sedangkan faktor eksternal sebesar 51,21%.

Abstract

Karya tulis ilmiah memiliki peran strategis dalam upaya pengembangan profesi guru. Sebagaimana diketahui bahwa karya tulis ilmiah merupakan salah satu butir penting bagi guru dalam meraih kenaikan pangkat. Namun pada saat ini, masih banyak guru-guru yang belum mampu mempublikasikan karya ilmiahnya pada jurnal ilmiah. Hal ini bisa terjadi karena kurangnya pengetahuan guru tentang tata cara penerbitan yang saat ini dilakukan secara online dengan sitem Open Journal System (OJS). Oleh karena itu, Program pengabdian kepada masyarakat pelatihan publikasi artikel ilmiah dengan menggunakan sistem OJS untuk guru MGMP Kimia Kota Pekanbaru yang bertujuan  untuk meningkatkan profesionalitas guru melalui peningkatan publikasi artikel ilmiah. Metodologi pengabdian yang digunakan adalah metode participatory action research. Kegiatan ini dilakukan dengan teknik penyuluhan secara langsung (direct), yaitu tim PPkM mengadakan pertemuan dengan guru Kimia SMA yang tergabung dalam MGMP. Kegiatan PkM dilakukan dengan 3 tahapan yaitu, Tahap perencanaan, Tahap pelaksanaan dan tahap Evaluasi. Kegiatan pengabdian kepada masyarakat yang dilakukan dalam bentuk Pelatihan Publikasi Artikel Ilmiah dengan Menggunakan Sistem OJS Untuk Guru MGMP Kimia SMA Pekanbaru telah berhasil  dilakukan dengan baik dan sesuai jadwa. Kegiatan pelatihan ini mampu memfasilitasi guru MGMP kimia SMA Pekanbaru untuk meningkatkan pengetahuan dalam melakukan publikasi artikel ilmiah dengan menggunakan system OJS dan Kegiatan pelatihan ini mampu memotivasi guru untuk melakukan peningkatan publikasi karya ilmiah.

Abstract

The aim of this community service program was to improve science teachers’ knowledge and skills regarding the identification of plant secondary metabolites and phytochemical screening. The program employed a Participatory Action Research (PAR) approach. The participants were 12 science teachers from Madrasah Cendekia Bangsa in Pekanbaru. Data were collected through training sessions, laboratory practice, observations, and questionnaires. The results showed an increase in teachers’ knowledge of plant secondary metabolite identification and phytochemical screening, with an n-gain score of 0.8. Teachers’ skills in conducting phytochemical screening tests of plant secondary metabolites were categorized as very good. In addition, the teachers were able to develop a teaching module on plant secondary metabolite testing using a rapid test phytochemical screening kit. The teachers’ positive responses indicated the perceived importance of understanding plant secondary metabolites for research in the pharmaceutical field. This community service activity specifically addressed teachers’ difficulties in understanding plant secondary metabolites and the limitations of practical equipment in school laboratories.
