The program that was implemented at Nurul Wathan (NW) was the result of research at the Rembitan Observatory to measure the earth's magnetism using a device called Proton. The international unit for measuring the earth's magnetism is the Tesla, specifically the nTesla earth magnet (Nano Tesla). The stages of implementing the solution are adjusted to the characteristics of the stages of the disaster cycle. During a disaster, full of activities in an emergency situation, post-disaster, reduce the complexity of the problems in reconstruction and rehabilitation. Pre-disaster requires thorough planning. Communities that are exposed to disasters are very diverse. For those who have been educated or those who have not received formal education, they need to understand the importance of disaster risk reduction (DRR).

Since the magnitude 7 magnitude earthquake occurred in August 2018, Lombok Island, especially North Lombok Regency, has been severely affected by infrastructure damage. From the data available, there are very few sources of clean water and are scarce. For this reason, in March 2019 the University of Mataram Community Service Team was represented by PUI Geomagnetic together with the largest water pump company in the world, Xylem Inc. installed a water pump at SDN 3 Teluk Nara Pemenang. The result of pumping water is clean water ready to drink.

The condition of the situation in Sade Village is a hill, slope and mountainous area with and has a marble of more than 20 degrees, a thick layer of soil above the hillside, there is a poor water and land use system, resulting in flooding and landslides. The incident occurred in early 2021. This was carried out by a community service program to anticipate the possibility of floods and landslides due to extreme weather. This service was carried out by the Research Group on Electro Magnetic Technology and Environmental Conservation for Humanity. One of the missions related to the village community is towards Tangguh Bencara Village (DESTANA).

Selong Belanak Village is part of the 9 buffer villages of the Mandalika Circuit. The condition of the village, which is known as a village that is often affected by floods, landslides and earthquakes every year, requires the Disaster Response Village Program (DESTANA). Program implementation is focused on having independent capabilities to have the ability to recognize threats in their area and be able to organize community resources to reduce vulnerability while increasing capacity to reduce disaster risk, prevent and anticipate disasters caused by human actions, respond to disasters to natural phenomena, adapt and face potential natural disasters, if after the disaster in order to be able to minimize the impact of the disaster. The method is carried out by carrying out the following activities: socialization about potential disasters, tree replanting activities (reforestation), cleaning beaches and houses of worship, and installing disaster signs. Community Service Efforts need ongoing training to improve the ability of DESTANA volunteers to improve their skills and abilities about DESTANA when dealing with natural disasters. The preparedness of DESTANA reminds us that we must continue to be alert to disasters

In the covid-19 condition, lectures at the Department of Electrical Engineering, Mataram University changed from a face-to-face process to via the Internet. T here will be a very sharp increase in demand. The use of data initially provided by the University of Mataram using a free hotspot network turned into a burden on lecturers and students. This research was conducted by sampling, general compulsory subjects, compulsory electrical courses, and compulsory expertise subjects. The distribution of variations of students domiciled in the City of Mataram and the other place coverage Lombok Island, within NTB and outside NTB. The results obtained are as follows: students who still survive in Mataram City are 17% (10.5 GB), Lombok Island 48% (8.1 GB), outside Lonbok Island 27% (4.8 GB), and outside NTB 8% (15 GB).
