Abstract

The purpose of this study was to analyze the level of validity of the HOTS-based two-tier multiple choice e-instrument with the theme let's be prepared for disasters to train students' critical thinking skills in class VII. The method used in this study is Research and Development (R&D) with research and development steps according to Sugiyono (2014) which are limited according to the needs of researchers including potentials and problems, data collection, product design, product validation, product revision. The research instruments used were media expert questionnaire sheets, evaluation experts and science teacher experts to measure the validity level of the e-instrument. The results showed that the e-instrument expert validation carried out by the media expert validator obtained an assessment percentage of 80.68% in the "valid" category, the evaluation expert validation obtained a rating percentage of 97.80% in the "very valid" category, and expert validation science teachers get an assessment percentage of 97.77% in the "very valid" category. So if the average percentage value of the experts is calculated at 92.08% so that the validity level of developing a two-tier multiple choice e-instrument based on HOTS with the theme let's be prepared for disasters to train critical thinking skills for class VII students falls into the "very valid" category.

Abstract

Siswa yang mempunyai pemahaman konsep yang baik dapat memanfaatkan pengetahuan tersebut untuk menyelesaikan berbagai permasalahan terkait. Penelitian ini bertujuan untuk menilai tingkat pemahaman mahasiswa Pendidikan Biologi terhadap mata kuliah biologi sel. Dengan menggunakan metode kualitatif dan pendekatan deskriptif, hasil analisis menunjukkan bahwa rata-rata pemahaman konsep siswa berada pada kategori rendah. Indikator pemahaman tertinggi terdapat pada konsep cell juction dengan persentase sebesar 70%, sedangkan indikator terendah terdapat pada pemahaman struktur perlekatan sel dengan persentase hanya sebesar 5% pada kelas sampel. Beberapa faktor yang menyebabkan rendahnya pemahaman konsep ini antara lain kesulitan dalam memahami soal-soal yang diberikan, perbedaan kemampuan akademik, rumitnya materi mengenai komunikasi antar sel, lemahnya daya ingat, dan kurang optimalnya proses pembelajaran.

Abstract

The problem in this research is to foster a community culture of the importance of a clean and healthy environment through waste management in their respective households. In this way, every member of the community is encouraged to care about the environment so that the environment remains clean and healthy because the waste problem absolutely must be handled optimally. The aim of this research is how to manage waste and the correlation between education level, family income level, behavior towards environmental cleanliness, knowledge about waste regulations. This research uses an observational analytical design. The relationship between the independent variable and the dependent variable is studied by taking momentary measurements and then conducting a correlation test. Household waste management in the Aek Parombunan sub-district has not been implemented optimally. Level of education, family income level, behavior towards environmental cleanliness, knowledge of waste regulations and willingness to pay levies waste is positively correlated with the way household waste is managed. The type of planning that can be applied in managing household waste in Aek Parombunan sub-district is transactive or social learning. Starting with fulfilling operational technical needs, namely household containerization and composting, communal waste sorting, village waste collection points for recycling, and sub-district TPS. Then increase community participation through empowerment and assistance by waste managers and other related agencies.

Abstract

There is a lack of learning media in teaching physics material, one of which is static electricity, so students feel bored because what is taught is only theory and ordinary explanations. So the aim of this research is to develop media using Canva Design on static electricity material. Research and development methods (Research and Development) using the Borg and Gall model. This research has only reached the initial field trial stage due to time constraints. The instrument is a material expert validation sheet consisting of 10 statements that assess the appropriateness aspects of the material as well as linguistic aspects as well as the media expert's validity of 7 statements, namely appearance and technical aspects. The validity value using a Likert scale of 1 to 4 shows the value for the appropriateness aspect of the material is 87.5% and the linguistic aspect is 83.3%, the appearance aspect is 82.5% and the technical aspect is 96.97%.
