Abstract

Penelitian ini bertujuan mendeskripsikan kelayakan LKPD berorientasi induktif untuk melatihkan keterampilan berpikir kritis peserta didik pada materi termokimia. Maksud dari analisis ini adalah untuk memaparkan kelayakan LKPD yang dikembangkan diperiksa dari validitas, kepraktisan, dan keefektifan. Metode analisis menggunakan rancangan research and development (R&D) melalui tahapan pengembangan dan validasi LKPD. Uji coba dilakukan secara terbatas untuk mendapatkan data empiris kepraktisan dilakukan di salah satu SMAN di Surabaya dengan One-Group Pretest-Posttest Design pada 7 peserta didik kelas XI MIA yang dipilih secara acak. Instrumen penelitian yang dipakai yaitu lembar telaah, lembar kevalidan, lembar tes, lembar pengamatan aktivitas siswa, dan angket respon siswa. Berdasarkan hasil penelitian dan analisis data, dapat disimpulkan bahwa pengembangan LKPD materi termokimia berorientasi model induktif untuk melatih keterampilan berpikir kritis yang memadai serta dipakai dengan memenuhi kategori valid dengan persentase 82,1275%, efektif dengan N-Gain yang diperoleh antara 0,7-1,0, dan kepraktisan dengan persentase ? 61% mendapatkan respon positif.

Abstract

Interviews with Chemistry teachers at SMA Negeri 3 Surabaya showed several problems, including low student motivation and teachers' lack of understanding of Chemistry concepts. The experimental study used a quantitative approach with a quasi-nonequivalent pretest-posttest control group experimental design. The Lab Rotation type Blended Learning model significantly improves students' problem-solving abilities in reaction rate chemicals. The results of statistical analysis showed P Alpha of 0.014 < 0.05, and t count (t Stat) 2.53 > t table (t Critical two-tail) 2.00. In conclusion, there is a positive influence of the blended learning model on the problem-solving ability of students in Chemistry material at SMA Negeri 3 Surabaya.

Abstract

The increasing influence of smartphones on young children has raised concerns about the delayed development of gross motor skills, particularly in early childhood. This issue is significant in Indonesia, which ranks fifth in ASEAN for birth rates, resulting in a large population of children at risk. Excessive smartphone use by children leads to decreased physical activity, potentially causing health problems such as obesity and reduced physical fitness. The objective of this study is to design and develop a portable system, called the "Mini Pump It Up," based on a mini-computer (Raspberry Pi 5), that encourages children to engage in more physical activities. This device is intended to divert children from excessive smartphone usage, thereby stimulating their gross motor skills development. Additionally, the system is designed to be used anywhere without requiring an external power source. The research concludes that the system successfully operates in portable mode without the need for a power supply, sustaining functionality for 3 hours, 10 minutes, and 15 seconds. Furthermore, the system effectively captures the interest of children, as evidenced by 84.21% of the 19 children participants choosing to interact with the product instead of engaging with smartphones.
