Need Analysis to Develop a Physics Module Integrated Natural Disaster and Mitigation

Physics is the study of phenomena, symptoms and interactions of objects that occur in nature. One of the phenomena that often occurs is natural disasters. Natural disasters are a series of events that occur naturally or non-naturally that can harm humans and anything in nature. Natural disasters can be prevented or reduced by doing mitigation. Mitigation is an effort carried out before a natural disaster occurs which aims to reduce or prevent the occurrence of natural disasters. In learning physics, natural disasters can be analyzed in physics concepts so that a teacher can make natural disaster phenomena a phenomenon that can increase students' knowledge in studying physics. Therefore, teachers need teaching materials that are integrated with natural disasters and mitigation to support learning to convey and analyze the role of physics in natural disaster phenomena and mitigation. The purpose of this study was to describe the teacher's need for the development of an integrated physics module for natural disasters and mitigation as teaching materials in physics learning. This research is qualitative research with the subject of research is physics teacher from several schools in Riau. Data collection was carried out using a non-test method by providing a questionnaire in the form of a google form. The results of the questionnaire show that most teachers need physics teaching materials in the form of an integrated physics module for natural disasters and mitigation.Physics is the study of phenomena, symptoms and interactions of objects that occur in nature.

Rancang Bangun Wastafel Otomatis Dengan Menggunakan Sensor Fotodioda

Covid-19 is a virus that causes mild and dangerous respiratory tract infections. To predict the spread and increase in the number of infected people, people are advised to adopt a healthy lifestyle by washing their hands. Currently, the faucets used mainly in the sink system are manual faucets. To open or close the faucet, the user must touch the faucet directly. So we need an innovation in this sink system. The innovation made is in the form of an automatic faucet with a photodiode sensor where the use of this sensor can later help make hand washing activities easier and more practical. By placing your hands in a certain position, water and liquid soap will come out automatically. The method used is the experimental method. The procedure of this research includes designing, assembling, and testing tools. The results of the experiment showed that when the hand accesses the sensor in the sink, the sink water automatically comes out, and when the hand is released no water comes out, this indicates that a person no longer needs to turn the water faucet to turn on the water.Covid-19 adalah virus yang menyebabkan infeksi saluran pernapasan ringan dan berbahaya. Untuk memprediksi penyebaran dan peningkatan jumlah orang yang terinfeksi, masyarakat disarankan untuk menerapkan pola hidup sehat dan mencuci tangan. Saat ini, kran yang digunakan terutama di sistem wastafel adalah kran manual. Untuk membuka atau menutup kran, pengguna harus menyentuh kran secara langsung. Maka diperlukan sebuah inovasi pada system wastafel ini. Inovasi yang dilakukan berupa kran otomatis dengan sensor Fotodioda dimana dengan penggunaan sensor ini nantinya dapat membantu kegiatan mencuci tangan agar lebih mudah dan lebih praktis. Dengan cara menempatkan tangan pada posisi tertentu, air dan sabun cair akan keluar secara otomatis. Metode yang digunakan adalah metode eksperimen. Prosedur penelitian ini meliputi perancangan, perakitan, dan pengujian alat. Hasil percobaan yang dilakukan menunjukkan bahwa saat tangan mengakses sensor di wastafel, air wastafel otomatis keluar, dan saat tangan dilepas tidak ada air yang keluar, hal ini menunjukkan bahwa seseorang tidak perlu lagi memutar kran air untuk menghidupkan Air tersebut
