The Covid-19 pandemic is one of the great catalysts that spurs transformation in the world of education. This encourages the importance of understanding teacher digital literacy in responding to educational transformation during the Covid-19 pandemic. The purpose of this Community Service (PkM) is to provide information and increase teacher knowledge of digital literacy during learning during the Covid-19 pandemic. The PkM targets are teachers in the provinces of West Java, Central Java, East Java, and DIY. The activity carried out was to provide education about the importance of digital literacy in responding to the transformation of education during the Covid-19 pandemic. The stages of this activity consist of 1) planning stage; 2) preparation stage, 3) implementation stage, and 4) evaluation stage. Before and after the activity, the PkM team provided a digital literacy questionnaire. The results of the PkM activity showed a significant increase in understanding of digital literacy, which was 21.3%.

Blended learning is the integration traditional classroom, e-learning, and selflearning methods using ICT based learning. One of them is through Edmodo supported by sufficient internet facilities. The aim of the research was to know the design of learning methods and the utilization of ICT based of blended learning in order to improve the understanding of the concepts in the 2nd Electromagnetic course. The reaserch was a descriptive class action by using qualitative and quantitative approach. All students of Physics Education in FKIP UST who take the 2nd Electromagnetic course were the subject of research. The sample was 28 students as respondents. The sample taking technique in the research used total sampling technique. The results showed that the utilization of Edmodo as the elearning tools in blended learning method was still at a moderate level. It was beacuse for students who took 2nd Electromagnetic course in 2015/2016 academic year were the first experience were not accustomed to active. Furthermore, it was beacuse of the limited internet connection facility. ICT-based of blended learning method as an appropriate educational technology effectively enough to help the learning process so that the lecturers and students could communicate interactively without place restrictions in anytime and anywhere.Keywords : Blended learning, Edmodo

Tanah longsor merupakan bencana yang disebabkan oleh beberapa faktor antara lain kondisi lapisan sedimen permukaan yang lunak, adanya getaran dan kodisi topografi (kemiringan lereng). Pada penelitian ini potensi gerakan tanah pada lerang yang dipicu gempabumi diidentifikasikan menggunakan pendekatan nilai ground shear strain dan pergerakan partikel yang diperoleh dari hasil analisis mikrotremor. Lokasi penelitian berada di Samigaluh, Kulon Progo yang merupakan daerah yang memiliki kerawanan tinggi mengalami tanah longsor. Data pengukuran mikrotremor sebanyak 15 titik diolah menggunakan software Geopsy. Hasil nilai ground shear strain bernilai antara 0,00045-0,00167 sehingga daerah penelitian rawan mengalami tanah longsor dengan potensi pergerakan tanah pada arah timur laut-barat daya.
