Disasters threaten the safety of vulnerable groups such the eldery, children and women. Based on the case of natural disasters that occurred in Indonesia, the need for a pragmatic strategy in forming the Indonesian people are aware of the dangers of natural disasters. One strategic step that taken is through the education sector. This research aims to create a disaster mitigation curriculum that has been formulated to produce disaster responsive learners. This research uses R&D (research and development method) by Borg and Gall (2003), in the stages of research and information, planning and initial product development. While for curriculum development used the Tyler model with the infusion method and block method. Data collection techniques used namely interviews, observation, and documentation. The findings of this research are based curriculum products to the stages of disaster mitigation include, 1) the concept of disaster mitigation curriculum, 2) The concept of the learning process (Intrakurikuler), 3) The concept of training process (Extracurricular, and 4) The concept of the assessment process (Evaluation). These results indicate curriculum products are made to increase disaster response capabilities of students through intracurricular and extracurricular activities as well as minimizing the impact of the disaster victims and improve disaster response capabilities for students in Indonesia. Keywords: Curriculum, Disaster Mitigation, Tyler's Model.
AbstrakTelah dibuat nanopartikel karbon dot dari daun teh olahan dan daun pepaya dengan menggunakan teknik microwave. Tujuan dari penelitian ini adalah mempelajari perubahan sifat optik pendaran nanopartikel karbon dot dengan uji fotoluminesensi. Untuk membuat karbon dot, daun teh olahan dan daun pepaya diekstrak menggunakan blender dan aquades, kemudian diletakkan dalam oven microwave 5, 10, 20 dan 40 menit. Penyaringan lanjutan dilakukan untuk mendapatkan nanopartikel karbon dot yang homogen. Pengujian fotoluminesensi dilakukan dengan mengeksitasi koloid karbon dot dengan laser dioda pada panjang gelombang 405 nm. Pendaran cahaya karbon dot direkam spektrometer. Pada umumnya pendaran cahaya karbon dot menghasilkan warna biru kehijauan. Hasil pengujian fotoluminesensi menunjukkan bahwa kurva pendaran karbon dot dari daun teh berbeda dengan daun pepaya. Waktu pemanasan sampel dalam microwave juga berpengaruh pada kurva pendaran karbon dot. Perubahan kurva pendaran menunjukkan struktur pita energi pada karbon dot tersebut. Dari penelitian ini dapat disimpulkan bahwa karbon dot dari bahan alam dapat mudah dibuat dengan teknik microwave dan sifat optiknya dapat diuji dengan teknik fotoluminesensi.Kata-kata kunci: karbon dot, fotoluminesensi, daun teh, daun pepaya. AbstractCarbon dot nanoparticles from processed tea leaves and papaya leaves produced using microwave technique have been made. The purpose of this research was to study the change of optical properties of carbon dot nanoparticles luminescence with photoluminescence test. To make carbon dots, processed tea leaves and papaya leaves were extracted using blender and distilled water, then were put in microwave oven for 5, 10, 20 and 40 minutes. Filtering was done for getting homogeneous carbon dot nanoparticles. Photoluminescence test was performed by exciting the colloidal carbon dot with a diode laser at a wavelength of 405 nm. Luminescent light of carbon dot was recorded by spectrometer. In general, luminescent light of carbon dots was cyan. The results of photoluminescence test showed that the luminescence curves of tea leaves and of papaya leaves were different. The sample heating time in microwave also affected the carbon dot luminescence curves. The change in the luminescence curve showed the structure of energy band on the carbon dot. From this study it can be concluded that carbon dot from natural materials can be easily made by microwave technique and photoluminescence technique can analyze the optical properties.
After the COVID-19 pandemic passed, the Indonesian government issued regulations encouraging the recovery of the education sector, such as guidelines for implementing the curriculum in the context of learning recovery. However, this is the problem, and teachers need help adjusting and developing learning plans due to the changes in the curriculum used. Based on these problems, this study aims to develop a digital-based learning design that simultaneously develops and utilizes virtual reality learning media on solar system material. This development research (R&D) type uses the ASSURE model involving media experts, material experts, and instructional design experts as research subjects. The data collection technique used was the provision of a closed questionnaire instrument. Data analysis technique using a percentage quantitative descriptive analysis approach. The results of the data analysis showed that three media experts gave an average score of 3.42, 3 material experts gave an average score of 3.61, and 3 instructional design experts gave a score of 3.31. It was concluded that the learning design and virtual reality media were declared valid and feasible. Learning designs and virtual reality media can be used for Class X SMA in Geography learning.
Sustainable development era has provided the government to increase foreign exchange earnings from non-oil and gas. Nganjuk Regency is one of the regions in East Java that has a number of tourism potential. However, lack of efforts from local governments and tourism managers in the delivery of tourist information, make tourists less aware of the beauty and uniqueness of tourism in Nganjuk Regency. Purpose of this study are designing Nganjuk.Hitz, a 360 o Tourism Web and Explain the results of its implementation. Employing Research and Development (R&D) method that uses the ADDIE model, data collection uses observation, documentation, and questionnaires using purposive sampling method and uses descriptive data analysis. Results of the study, after testing through web browsers, the tourism information system based on Nganjuk.Hitz 360 o Tourism Web is successfully stated. Usability test results state that respondents feel this tourism information system is interesting, easy to understand, complying the needs, easy and convenient to use, and in turn, are interested to visit the tourism destination.
