Railway travel safety is an important component in rail transportation. The reliability of the railroad infrastructure is one of the points to support the safety of railroad operations. Lintas Bandung - Cikampek is a cross that has varied geographical contours where right-left rail roads have hills and slopes so that the area between Purwakarta Station - Ciganea Station is a landslide-prone area. As happened in the field there was an avalanche at KM 107 + 100 - KM 107 + 300 which caused disruption to train travel. In addition, improper handling of landslides will cause other potential dangers. The handling of the landslide slope in KM 107 + 100 - KM 107 + 300 uses steel tape from the used rails because the landslide is considered to be less than optimal and is looking for other ways to handle landslides. looking for comparisons compared to using the shotcret method. In this study, we tested the landslide handlers that have been carried out by comparing the handling carried out in accordance with the existing provisions between the steel plaster method of the rail used with the shotcrete method. The cause of landslides is due to a steep angle of 65⁰ with a peak height of 15 meters. The impact on crossing is applied to taspat 5 km / hour to anticipate sudden landslides. From the results of the analysis, it was found that the shotcrete method was considered capable of handling landslide-prone areas in KM 107 + 100 - KM 107 + 300. However, for the handling that had been carried out using steel plaster from used rails. However, this handling is considered not optimal because of the limited number of rails around vulnerable areas, resulting in plaster walls that can still make material exit to the railroad tracks.

The role of Science and Technology (IPTEK) in the development of the times has a significant contribution. In the midst of the development of educational technology, the education curriculum is also involved in the development of culture that is integrated in school learning with the aim that students can become a generation with character and able to maintain and preserve culture as the foundation of national character. The education curriculum is required to always develop in accordance with the progress of the times as well as cultural involvement in learning in schools in order for students to be able to recognize the culture of the ancestors who have character and able to maintain and preserve culture as the foundation of the nation's educational character. Cultural practice allows for the inculcation of mathematical concepts into reality. More specifically in the learning of mathematics there are factors that affect the learning achievement of learners. These factors are attached to the ability of learners in learning mathematics. The role of ethnomatics is able to evoke the understanding of learners in the process of learning mathematics is certainly related to the cultural treasures that are inherent in the society where learners and schools are located. Ethnomathematics brings out cultural wisdom so that it is able to motivate students in learning mathematics. The description of the study in this article includes the exploration of ethnomathematics from various areas that show the relationship between ethnomathematics and the basic concepts of mathematics learning

Learning during the pandemic is carried out online (in a network) by paying attention to the situation and conditions when the Covid-19 outbreak hit the whole world. Online learning began in 2020 to be precise in March so that up to this research it had been exactly one year. However, in its implementation, there are many discrepancies, this is indicated by several problems that occur in the field. From the research results, it was found that the online learning models that were widely used were WAG (Whatsapp Group), Google For Education (Google Form, Google Classroom, Google Drive), Youtube, Zoom Meeting. The obstacles experienced were unstable communication signals, exhausted internet quota, parents' cellphones brought to work, students accompanied by their parents working on assignments at night. Meanwhile, the advantages of online learning are flexible, complete reference sources, and adaptive to technology. Of the student activity level, only 50% are fully active in online learning, 32% are active and the remaining 28% are inactive
