Abstract

Lombok is an area with the highest geomagnetic anomaly in Indonesia (Zubaidah et al., 2014). From the end of July to the end of August 2018, Lombok experienced a series of fairly large earthquakes. Identification of geomagnetic signals, especially in the Ultra Low Frequency (ULF) spectrum, can be used as earthquake precursors (Saroso, 2010). Intermagnet IAGA (International Aeronomy Geomagnetic Association) is a network of international geomagnetic observatory stations that have large world geomagnetic data. Big data analysis is very important because very large information is needed in disaster mitigation. This study uses geomagnetic data per second for 24 hours from 28 August to 30 November 2018 taken from Kakadu (KDU) Australia and Nurul Bayan Station (NRB) Lombok. The analytical method used is Differentiation by calculating the F value (total magnetic field) for KDU and NRB, then look for the difference and analyze the pattern. The results found that there was an anomaly phenomenon of the Earth's magnetic field in Nurul Bayan Lombok which was detected for 17 days during October 2018.

Abstract

Background: Users or recipients of SMK graduates are focused on the field of Network and Computer Engineering providing input so that graduates are ready to use. Training to improve the quality of graduates really needs to be held in a community service program. The training was carried out at the Integrated Vocational School of the Gema Cendikiawan Muslim Foundation (YGCM) in Central Lombok, which is very closely related to improving the learning curriculum in the field of Computer and Network Engineering. This increase is related to the very rapid development of technology accompanied by the need for uptake of graduates who can work according to the abilities obtained at the SMK bench. Purpose: The activities carried out are to motivate enthusiasm to be raised by teaching and learning process activities for teachers and students given an overview of current conditions and the future, so that future technology is still used according to the basic competencies given to students by improving the curriculum according to market share needs. Method: Motivation is carried out before designing the curriculum so that in the process of determining curriculum outcomes, minimum requirements are obtained to suit users of SMK graduates, discussions with surfing the internet continue to be carried out as an effort to produce graduates as optimally as possible. Results: Teachers and students are very enthusiastic about participating in the program, it was found one important thing in this program is the importance of knowledge of healthy Internet use, especially IoT in the future, the curriculum obtained from this activity adopts market demand of around 76% Conclusion: This training should continue to be implemented so that the curriculum continues to be updated according to the needs of the market share.
