Penelitian ini dilaksanakan untuk mengembangkan modul kimia yang mengaitkan kimia dalam kehidupan sehari-hari khususnya dalam bidang kewirausahaan. Tujuan dari penelitian pengembangan ini yaitu menguji kualitas dan keterlaksanaan dalam proses pembelajaran dengan menggunakan modul kimia berbasis inkuiri terbimbing berorientasi Chemo-Entrepreneurship pada materi sifat koligatif larutan. Pengembangan ini menggunakan model 4-D (tanpa disseminate) yang terdiri dari 4 tahap yaitu define, design, development, dan disseminate. Penilaian kualitas produk dilakukan oleh ahli materi, ahli media, 3 Peer Review, 3 guru kimia, dan 10 peserta. Uji keterlaksanaan diamati oleh 3 observer dan direspon oleh 30 peserta didik. Proses pengambilan data kualitas modul dengan menggunakan angket dan uji keterlaksanaan dengan menggunakan lembar observasi yang telah divalidasi oleh dosen ahli instrumen. Data yang diperoleh dianalisis guna mengetahui kualitas modul kimia dan keterlaksanaan proses pembelajaran dengan menggunakan modul yang dikembangkan. Hasil penelitian menunjukkan bahwa persentase penilaian kualitas yang diperoleh dari ahli media 86,84% dengan kategori Sangat Baik (SB), ahli materi 82,14% kategori Sangat Baik (SB), guru kimia 83,33% kategori Sangat Baik (SB), dan peserta didik 87,5% kategori Sangat Baik (SB). Uji keterlaksanaan memperoleh persentase rata-rata 90,3% dengan kategori Sangat Baik (SB) dan direspon positif oleh peserta didik dengan perolehan persentase sebesar 91,25%.

The study aimed to determine the level of Senior High school students’ problem-solving skills and to identify students’ problem-solving skills based on gender. This study was a descriptive study by using survey method. The population of this study was all of the eleventh-grade students from mathematics and natural science class in SMA N 1 Temanggung, SMA N 3 Temanggung, and SMA N 1 Pringsurat, with 191 students as the sample. The sampling technique was cluster sampling. Data collection was conducted by providing a question in the form of problem-solving essays. The score category level to analyze student’s problem-solving skills level and inferential statistics with independent sample t-test to analyze problem-solving skills based on gender. The result of the study showed that (1) the problem-solving skills level of Senior High school students in Temanggung mostly in the moderate category, (2) there is a significant difference of problem-solving skills in students based on gender. Female students have higher problem-solving skills than male students.

This study aims to determine the difference between Higher Order Thinking Skills (HOTS) and Students Self Regulated Learning (SRL) before and after using e-module based on the 7E (elicit, engage, explore, explain, elaborate, evaluate, and extend) learning cycle on the buffer solution material, and to determine the percentage of its effectiveness. The research use a quasi experiment with one-group pretest-posttest design. The subjects of this research were students of natural science 11th grade in one of senior high schools in Yogyakarta. The instrument used were test in the form of HOTS pretest-posttest description question and non-test in the form of self-regulated learning questionnaire. The data analysis technique used is Hotteling's T2 test. The results showed that the significance value was 0.000 < = 0.05, then H0 was rejected. There were differences in students' HOTS and SRL before and after using e-module based on the 7E learning cycle. The effectiveness of using e-module show by HOTS and SRL simultaneously (36.8%), HOTS (25.2%), and SRL (20.5%).
