Penelitian inii bertujuan untuk mengetahui pengaruh pembelajaran PISI dalam meningkatkan hasil belajar kimia siswa kelas XI semester 2 SMA Muhammadiyah 3 Yogyakarta tahun ajaran 2014/2015. Penelitian merupakan eksperimen semu yang terdiri terdiri dari variabel bebas berupa model pembelajaran dan variabel terikat berupa hasil belajar. Populasi penelitian ini adalah 143 siswa kelas XI SMA Muhammadiyah 3 Yogyakarta pada semester kedua Tahun ajaran 2014/2015. Sampel penelitian ditentukan dengan teknik purposive sampling yang terdiri dari dua kelas. Kelas eksperimen menggunakan model pembelajaran PISI dan kelas kontrol menggunakan model pembelajaran 5M dalam materi larutan penyangga. Teknik pengumpulan data melalui teknik tes dan teknik dokumentasi. Teknik analisis data yang digunakan adalah uji-t beda subjek dengan taraf signifikansi 0,05. Hasil penelitian menunjukkan bahwa terdapat pengaruh pembelajaran PISI dalam meningkatkan hasil belajar kimia siswa kelas XI semester 2 SMA Muhammadiyah 3 Yogyakarta tahun ajaran 2014/2015.

Siswa masih mengalami kesulitan dalam memahami konsep larutan penyangga, sehingga penelitian ini bertujuan untuk mengetahui peningkatan pemahaman konsep larutan penyangga dengan menerapkan model pembelajaran POGIL (Process Oriented Guided Inquiry Learning). Penelitian ini dilakukan di SMA Negeri 5 Kota Serang kelas XI tahun ajaran 2017/2018. Metode yang digunakan dalam penelitian ini adalah metode quasi eksperimen dengan desain penelitian two group pre test post test design. Sampel penelitian ini terdiri dari 59 siswa yang terbagi menjadi 2 kelas, yaitu 29 siswa kelas eksperimen dan 30 siswa kelas kontrol yang diperoleh dengan menggunakan teknik purposive sampling. Pengumpulan data pemahaman konsep siswa diperoleh dengan menggunakan instrumen tes. Hasil penelitian mengungkapkan pemahaman konsep larutan penyangga yang diajarkan dengan menggunakan model pembelajaran POGIL mengalami peningkatan yang signifikan yang ditunjukan dengan nilai rata-rata gain sebesar 0,44 yang berada pada kategori sedang.

This research is a research and development (R&D) research that aims to find out the development procedures while producing products and the quality of the Selvo E-module application as a learning medium on the topic of voltaic cells. Research and development is carried out by adapting and modifying the Borg & Gall development model trough preliminary study and development stages with limited trials involving the validation of five media experts. Analysis of the data used during development is descriptive analysis and percentage techniques. The sample in this research were students of class XI MIPA Academic Year 2018/2019. The results showed that the development of chemistry e-module has “very good” qualifications for the material aspect with a percentage of 92% and media with a percentage of 97% according to experts. Based on the responses given by students as an assessment sample, the quality of the Selvo E-module application is included in the excellent category with a percentage of 85.24%.

Learning chemistry requires practicum which functions to enrich understanding of chemical materials. Practical practice should ideally be carried out in a laboratory as a representative place to produce accurate and precise data using validated practical instructions. This study aims to create a chemistry practicum guide that is designed to be carried out at home with facilities around the house so that it can function to train student independence. This research is a product development research in the form of using model Analyze, Design, Develop, Implement, and Evaluate (ADDIE). The resulting product was validated by 6 material and media expert validators and then tested limited to 15 chemistry teacher candidate students. The results showed that the practicum instructions obtained an Aikens score of 0.9 from the validator, which means they are valid and feasible to try out. Then after conducting trials and student responses, a response of 86% was obtained in the very good category. Based on the values from the validator and limited trials, these practical instructions can be used by prospective Chemistry teachers in teaching in the classroom and at home.
