Abstract

Chemistry is one of the fields of science that involves many concepts and is prone to misconceptions. This is because books, information from other people and the internet, misinterpreted experiences, and other sources provide inaccurate or incomplete information. Teachers are responsible for transferring knowledge or information and ensuring that the knowledge or information is understood correctly so that the teacher's ability to detect students' conception profiles becomes one of the competencies that teachers must have. Chemistry teachers in Mojokerto Regency and City need to map students' conceptions related to chemical concepts not only considering aspects of students' thinking skills. This is the basis for the community service team who have the initiative to provide training on Student Concept Mapping on Chemistry Material in Mojokerto Regency and City. The results obtained were that teachers' understanding of the development of diagnostic tests improved, from 57.14% to 88.09% and was proven by the preparation of diagnostic tests developed by teachers on acid-base, chemical bonds, and hydrocarbon materials.

Abstract

Telah ditemukan fakta bahwa guru-guru di Sekolah Indonesia Kuala Lumpur (SIKL) belum terlatih dalam mengembangkan LKPD berbasis proyek dan belum mendapatkan pelatihan pengembangan LKPD berbasis proyek. Pembelajaran berbasis proyek merupakan salah satu program yang diwajibkan dalam implementasi kurikulum merdeka. Oleh karena itu dirasa sangat penting untuk melakukan pelatihan pengembangan LKPD berbasis proyek untuk guru-guru di SIKL. Tujuan kegiatan PKM ini adalah untuk melatih guru-guru dan relawan dibawah naungan SIKL dalam pengembangan LKPD berbasis proyek dan menerapkan LKPD tersebut dalam pembelajaran di SIKL serta mengetahui respon peserta terhadap kegiatan PKM. Kegiatan dilakukan mulai dari koordinasi awal dengan pihak SIKL, persiapan, pelatihan dan monitoring evaluasi. Hasil kegiatan menunjukkan bahwa guru SIKL telah memahami tentang pembuatan LKPD dan melaksanakan pembelajaran berbasis proyek. Hasil respon peserta menunjukkan bahwa semua peserta menyatakan setuju dengan kegiatan pelatihan ini dan mengharapkan kegiatan yang sama di lain waktu. Selanjutnya diharapkan guru-guru di SIKL terus melanjutkan pengembangan dan pengimplementasian pembelajaran berbasis proyek sebagai bentuk pengembangan kreatifitas siswa Indonesia yang ada di Kuala Lumpur.

Abstract

This study was conducted to analyze the feasibility of PBL-based LAPD in developing critical thinking skills in Phase F of buffer solution material. The feasibility of LAPD was evaluated based on the aspects of validity, practicality, and effectiveness. The research design applied was Research and Development (R&D) with the 4D Thiagarajan development model, which includes definition, design, and development. Limited-scale testing was applied to grade XI students at Widya Darma High School in Surabaya. The feasibility analysis of LAPD in terms of content validity, construct validity, and graphic validity showed a mode score of 5, which is classified as very good. The practicality of the LAPD was proven by a student response rate of 90% and an activity observation result of 93.30%, thus classified as very practical. The effectiveness aspect was determined based on the pretest and posttest critical thinking scores. Testing with the paired t-test method obtained a right-hand p-value of 0.000 (<0.05), so the alternative hypothesis H1 was accepted and H0 was rejected. This improvement was supported by a critical thinking N-gain value of 0.77 in the high category, as well as student learning outcomes of 87.5, which had reached mastery. The analysis results indicate that PBL-oriented LAPD is feasible to be applied to train critical thinking on buffer solution material.

Abstract

Miskonsepsi kimia adalah kesalahan dalam memahami konsep-konsep dasar seperti struktur atom, ikatan kimia, dan reaksi kimia. Miskonsepsi dipengaruhi oleh strategi pengajaran yang kurang menekankan pada rekonstruksi konseptual peserta didik. Upaya yang dapat dilakukan untuk mengatasi miskonsepsi adalah melalui pembelajaran remedial Conceptual Change. Pembelajaran remedial mudah dilaksanakan melalui Penelitian Tindakan Kelas (PTK). Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mendampingi guru kimia di Kota dan Kabupaten Mojokerto dalam mengimplementasikan PTK sebagai upaya mengatasi miskonsepsi peserta didik. Pendekatan yang digunakan adalah pendampingan berkelanjutan melalui pelatihan, praktik penyusunan perangkat pembelajaran, serta implementasi PTK berbasis Conceptual Change. Kegiatan dilaksanakan sejak April hingga November 2025 dan melibatkan guru kimia anggota MGMP Kota dan Kabupaten Mojokerto. Tahapan kegiatan meliputi persiapan perangkat pelatihan, pendampingan penyusunan proposal PTK dan Lembar Kegiatan Peserta Didik berbasis Conceptual Change, pendampingan pelaksanaan PTK hingga dua siklus, serta evaluasi dan refleksi hasil kegiatan. Data dikumpulkan melalui tes diagnostik konsepsi, angket, observasi, dan analisis laporan PTK peserta. Hasil kegiatan menunjukkan peningkatan pemahaman guru terhadap miskonsepsi peserta didik, pemahaman mendalam dan penguasaan teknik PTK, mulai dari karakteristik, siklus pelaksanaan, hingga kemampuan merancang proposal PTK yang secara spesifik berfokus pada upaya reduksi miskonsepsi, dan respon positif dari guru sebagai peserta pelatihan. Berdasarkan hasil tersebut, dapat disimpulkan bahwa kegiatan PkM telah mencapai tujuan yang ditetapkan. Saran untuk pelaksanaan PkM tahun berikutnya adalah pelatihan penulisan artikel ilmiah sebagai hasil PTK untuk mereduksi miskonsepsi kimia peserta didik.

Abstract

The purpose of this study is to develop student worksheets based on the NHT cooperative learning model to train students’ communication skills regarding reaction rates. This Research and Development project employs the 4-D model (Define, Design, Develop), omitting the Disseminate. A limited pilot test was conducted with twelve students from Class XI-1 at Ngoro State Senior High School, Jombang in the second semester of the 2025/2026 academic year using One Shot Case Study design. The feasibility of the worksheets was assessed in terms of validity, practicality, and effectiveness. Data were collected using validation sheets, student response questionnaires, activity and oral communication observation sheets, and cognitive learning outcome tests. Validation results showed that the worksheet met valid and highly valid criteria with mode values of 3 and 4 for content and construct validity. Practicality was demonstrated by 85,71% of student response questionnaire items categorized as very positive, and 92,35% of student activities observed as very good. Effectiveness was reflected in improvements in oral communication skills; the quantity of opinion-giving increased from 50% to 58,3% and question-asking from 33,3% to 41,6%, both in the fairly good criterion. The quality of oral communication also improved, with opinion quality rising from 41,67% to 44% and question quality from 36,1% to 41,6%, both categorized as fairly good. Written communication quality across all groups reached ≥66,67%, categorized as good. All students achieved cognitive learning mastery with scores of ≥75. Thus, the developed NHT-based worksheets are suitable for training students’ communication skills on reaction rate material.
