Pandemic Coronavirus Disease (COVID-19) is a non-natural disaster that occurs globally. Disaster mitigation efforts need to be made when entering a new normal life after the physical distancing policy is relaxed. The purpose of this study was to describe the knowledge and participation of students in disaster mitigation activities during the new normal period. The research method used descriptive, data collection techniques through Google Form with a sample of 54 students. The results showed that learning of disaster mitigation education is not maximally taught at the university level with a percentage of 57.4% for students, who did not receive disaster mitigation education. However, as many as 51.9% of students had attended training in disaster education. Disaster mitigation education was important to do when a new normal period. That is because students are one component that has a role to convey various information about the disaster, especially COVID-19. This study concludes that knowledge and student participation in disaster education still needs to be improved. The suggestion from this research was necessary to develop innovative learning tools for disaster mitigation education in the new normal era of COVID-19.

Learning in the 21st century requires a learning innovation, especially in science and environmental learning. That's because solving various environmental problems requires students' abilities, one of which is Higher Order Thinking Skills (HOTS). The purpose of this research was to develop a learning model called ITA (Identify problems, Think and Write, Analysis and Argumentation). This research was conducted in March 2020. The method used in this research was research and development. Validation was carried out for 11 validators via Google form (online media), consisting of 5 learning experts and 6 science teachers. The results of the study showed that the ITA learning model was categorized as very valid with an average score of 3.52 which could be interpreted as an ITA learning model suitable for use in science and environmental learning. Other innovations to support the implementation of the ITA learning model can be developed to strengthen the use of the ITA learning model. This study concludes that the ITA learning model is suitable for use in science and environmental learning.

Natural science and environmental learning in the 21st century require Higher order thinking skills (HOTS). The purpose of this study was to develop an ILMIZI learning model. The method used is research and development carried out in June-July 2019. The results of the study showed that the ILMIZI model syntax consists of 6 stages, start from Identify problem, Limitation problem, Make mind map, Interpret result, Analyze result, Interaction and evaluate. The six stages are the results of development which are expected to have an impact on the rise of HOTS. Validation results from various learning experts and teachers showed a score of 3.74 with a percentage of 93.50% and a very valid category which means that the ILMIZI model is suitable for use in natural science learning (biology, physics, chemistry) and environmental learning at all levels of education. The conclusion is that the ILMIZI learning model was suitable for learning and expected to have an impact on HOTS students

Environmental learning in schools should be based on Higher Order Thinking Skills (HOTS) and based on environmental problems, one of which is Green Consumerism (GC). The problem is the absence of student HOTS profiles based on GC. The purpose of this study was to measure students HOTS based on GC concepts and present them descriptively in the form of profiles. The study was conducted in November-December 2018 at State Junior High School 1 in South Tambun, Bekasi, West Java, Indonesia. The research method used is descriptive research. The sample used was 128 students in grade 8th, consisting of 42 male students and 86 female students. The results showed that GC-based HOTS scores were still relatively low. Students overall got an average score of 31.55. The aspect with the highest score was obtained in the analyze (C4) aspect with a score of 3.81, while the aspect with the lowest score was on the create aspect (C6) with a score of 2.57. This is because the information about GC is still not obtained by many students. The conclusion is that students' HOTS scores are low and need to be improved.

Environmental learning at the school and university levels, often still uses conventional learning. This is a problem, considering the ability of students' Higher Order Thinking Skills (HOTS) is very necessary for the 21st century. The purpose of this study is to do need assessment on learning media, teaching materials, learning materials, worksheets, and learning evaluations used in the learning environment in schools and universities. The study was conducted from November 2017 - January 2019 at several schools in Bekasi and one university in Jakarta. The research method used is descriptive method with data collection techniques using observation and interviews. The results showed that media learning, teaching materials, learning materials, students worksheets, and learning evaluations at various levels were not all based on HOTS. HOTS-based learning has been applied at the university level and senior high school but is still rarely used. This is due to the lack of development in environmental learning. The conclusion of this study is that environmental learning is not all HOTS-based.
