Abstract

This study aims to determine and analyze the need for the development of microcontroller-based physics bullet motion tools to stimulate students' concept understanding on the subject of parabolic motion. This type of research is Research and Development (R&D) using the 4D research method (define, design, develop, disseminate) focused on the define stage. At the define stage, a needs analysis (need assessment) was conducted. This research is a quantitative descriptive research. Data collection techniques in this study were observation and questionnaire to analyze the needs of physics teachers and students of class XI MIA MAN 2 Deli Serdang. Based on the results of the research conducted, it can be concluded that 1) Teachers need learning media in the form of teaching aids that can help stimulate understanding of concepts on the subject of parabolic motion 77.5% with the category agree. 2) Students have an interest in the implementation of learning by conducting experiments and using learning media in the form of teaching aids by 100% with a strongly agreed category. 3) There is no use of learning media in the form of microcontroller-based props that can help stimulate understanding of physics concepts on the subject of parabolic motion by 100% with a strongly agreed category

Abstract

Disaat sumber energi lain mulai menipis dan memberikan dampak negatif, maka air menjadi sumber yang sangat penting karena dapat dijadikan sumber energi pembangkit listrik yang murah dan tidak menimbulkan polusi. Pembangkit tenaga listrik Picohidro pada dasarnya memanfaatkan beda ketinggian serta jumlah debit air per detik yang ada pada aliran air irigasi, sungai atau air terjun. Kemudian energi ini dihubungkan dengan generator listrik yang nantinya akan menghasilkan energi listrik. Menurut Robert, keunggulan teknologi PLTPH adalah cocok digunakan di daerah terpencil. Piko Hidro hanya butuh ketinggian air 1-3 meter dan debit 30 liter per detik. Jadi cocok digunakan di daerah terpencil. Selain itu biaya investasinya pun tergolong murah sekitar Rp 30 juta per unit dengan biaya pemeliharaan yang minimum dan tidak memerlukan biaya bahan bakar. Piko Hidro ini pun mudah dirakit dan dioperasikan serta bisa beroperasi selama 24 jam sesuai dengan debit air. Teknologi ini membuatnya cocok untuk diterapkan di daerah terpencil yang memiliki debit air yang sesuai.
