Pembelajaran dikelas dapat berjalan dengan baik jika proses pembelajaran juga berjalan dengan baik. Penelitian ini bertujuan untuk mengetahui aktivitas siswa terhadap penerapan media Word Square dalam pembelajaran kimia pada materi struktur atom, mengetahui hasil belajar siswa dengan menggunakan media Word Square pada materi struktur atom dan mengetahui respon siswa terhadap penerapan media Word Square dalam pembelajaran kimia pada materi struktur atom. Teknik pengumpulan data yang digunakan pada penelitian ini adalah lembar observasi, tes berupa pre-test dan post-test dan angket respon. Hasil penelitian menunjukkan bahwa 1) Aktivitas belajar siswa terhadap penggunaan media pembelajaran word square pada materi struktur atom sangat baik, berturut-turut sebesar 79,17 dan 83,00. (2) Hasil belajar siswa terhadap penggunaan media pembelajaran word square pada materi struktur atom yaitu sebesar 92,59. (3) Respon siswa terhadap penggunaan media pembelajaran word square pada materi struktur atom sangat positif, yaitu sebesar 91,66 dan respon negatif yaitu sebesar 8,33.

This Community Service activity aims to explain the use and benefits of the Mendeley application to prospective teachers. This activity was carried out for two days from 5-6 June 2023. The stages of this activity consisted of the preparation stage, the implementation stage and the evaluation stage. The community service activities that have been carried out have succeeded in increasing the knowledge and understanding of participants in using and utilizing the Mendeley application for writing scientific papers.

Community service activities have been carried out at SD Negeri 9 Dewantara. This service program aims to introduce basic measuring tools to improve and support student science learning which starts from grade IV of Elementary School. The basic measuring tool introduced is the measuring tool for length. The material presented includes names, functions and how to use ruler measuring instruments, calipers, and screw micrometers. The introduction of measuring instruments with the inquiry method or direct practice is proven to improve students' science process skills. This is because students are actively involved in every learning process.

Practical guide is a learning resource that can minimize the role of lecturers, making students more active and have creative thinking and skills so that it is easier to carry out activities in the laboratory. This research was aimed to obtain Biochemistry practicum guides integrated discovery learning (DL) in the study program of Agrotechnology and to determine the feasibility of Biochemical practicum guides integrated discovery learning according to the national standards of higher education. The research design used the Research and Development (R & D) method with model of ADDIE (analysis, design, development, implementation, and evaluation). This research is only done in the development stages of the practical guides. The feasibility of the Biochemical practicum guide was assessed descriptively based on assessment scores from expert validators as many as four chemistry lecturers. The results showed that Biochemical practicum guides integrated discovery learning in the study program of Agrotechnology in accordance with national standards of higher education with an average value from expert validators for feasibility of content 3.83, feasibility of language 3.81, feasibility of presentation 3.91 and feasibility of graphic 3.91.
