PPenelitian ini bertujuan untuk 1) mengetahui pengaruh kesiapan laboratorium terhadap pemanfaatan laboratorium pada pelaksanaan praktikum kimia, 2) mendeskripsikan kendala yang dihadapi dalam memanfaatkan laboratorium pada pelaksanaan praktikum kimia di SMA se kota Langsa. Metode penelitian yang digunakan adalah deskriptif korelatif. Jenis penelitian ini adalah penelitian survei. Teknik pengumpulan data menggunakan instrumen observasi, angket dan wawancara. Data hasil penelitian dianalisis menggunakan rumus regresi linear sederhana. Hasil penelitian menunjukkan korelasi kesiapan laboratorium terhadap pemanfaatan laboratorium pada pelaksanaan praktikum kimia adalah 0,44 atau 44%. Pengaruh kesiapan laboratorium terhadap pemanfaatan laboratorium pada pelaksanaan praktikum kimia dapat diketahui melalui persamaan regresi: Y = 0,4176 (X) + 52,839. Kendala utama yang dihadapi guru dalam memanfaatkan laboratorium pada pelaksanaan praktikum kimia di SMA se kota Langsa adalah ketersediaan bahan kimia dan waktu mempersiapkan alat dan bahan praktikum. Selain itu, guru bidang studi membutuhkan pelatihan mengenai pengelolaan dan manajemen laboratorium yang baik sehingga meningkatkan motivasi pemanfaatannya.

Indonesia is one of the positive countries for the corona virus (Covid-19). Experts cite several reasons for the increasing number of cases, one of which is the attitude of the public who careless about minimizing contact between people, the lack of sanctions for violations of self-quarantine, and the lack of location information that the community must avoid. The attitude of caring society, especially education actors, is certainly one of the important things that needs attention. Environmental care and responsibility are character values that need to be developed. Students can get character education through the learning process and learning resources, one of which is textbooks. The purpose of this study was to determine whether there is an integration of character values and what is the percentage of integration of character values in high school chemistry textbooks that have been used by teachers in learning, especially the character of environmental care and responsibility. This research is a quantitative descriptive study using the questionnaire and observation sheet instruments. The sample in this study is the class X chemistry textbook that is most often used in teaching and learning activities at SMA Negeri 2 and SMA Negeri 4 Langsa City. The results showed that there was an integration of the character values of environmental care and responsibility in the X grade chemistry textbooks used by teachers of SMA Negeri 2 and SMA Negeri 4 Kota Langsa. The integration of environmental care character values is 38%, while the responsibility character values is 63%. The integration of the character values of environmental care and responsibility in the class X chemistry textbook appears in the column project activities, student activities, content content, and evaluation.

The values ​​of character in the classroom can be applied through practical activities. Therefore, the learning needs to be applied using lab modules that foster student character values. The purpose of this study was to describe the value of independent character, Environmental Awareness, and curiosity of students on the application of the lab module for the use of secondary metabolites. The research was a descriptive study. It was conducted at Samudra University, Langsa City. The research subjects were students of chemical education at FKIP Samudra university. Data in this study were obtained through interviews and questionnaires. The questionnaire analysis technique was performed using a percentage formula and interpreted to determine the student character value categories. The results showed the average student character values ​​in the use of the lab module secondary metabolite utilization are 84% in the excellent category. Based on the statistical tests, sig. 0.00 showed that the character values ​​of students in the use of lab modules were on average above 50. The results of this study are expected to be information for researchers to develop integrated lab modules for character values.

Perkembangan teknologi informasi dalam bidang pendidikan seperti modul elektronik dapat membantu dalam proses pengajaran. Penelitian ini bertujuan untuk mengetahui kelayakan serta kemenarikan media yang dihasilkan dengan menggunakan aplikasi exe-learning. Dengan menggunakan model ADDIE, penelitian ini termasuk dalam penelitian dan pengembangan atau Research and Development (R&D). Penelitian ini baru sampai pada tahap pengembangan modul elektronik interaktif. Subjek penelitian ini adalah ahli materi, ahli media, guru kimia dan peserta didik. Teknik pengumpulan data yang digunakan adalah lembar validasi ahli media, ahli materi, angket respon guru dan angket respon peserta didik untuk memperoleh data kuantitatif sebagai data mentah dan data kualitatif sebagai saran dan masukan untuk perbaikan media pembelajaran modul elektronik interaktif. Data kuantitatif yang diperoleh kemudian diubah menjadi data kualitatif dengan menggunakan kriteria penilaian. Hasil penelitian berupa media pembelajaran kimia e-modul interaktif  kelas X semester I dengan menggunakan aplikasi exe-learning. Adapun hasil penilaian yang diperoleh berupa kelayakan materi sebesar 92% dengan kriteria sangat layak, kelayakan media sebesar 91% dengan kriteria sangat layak, hasil angket respon 5 guru kimia di SMA Negeri Langsa sebesar 95% dengan kriteria sangat menarik dan hasil angket respon 15 peserta didik sebesar 98% dengan kriteria sangat menarik. Berdasarkan hasil penilaian diatas dapat disimpulkan bahwa media pembelajaran kimia e-modul interaktif kelas X semester I dengan menggunakan aplikasi exe-learning yang dikembangkan layak digunakan dalam proses pembelajaran.
