Padang city is one of the areas prone to earthquakes and tsunamis. With this fact, the city government of Padang created a number of gathering points or shelters equipped with evacuation routes for residents of Padang city. Likewise in West Padang District which is the area closest to the beach and has a high population. From the results of the data collected, then the authors use the Research and Development method. From the results of this study, an Android-based Geographical Information System (GIS) was designed, information can be conveyed in a visual form in which there is information related to tsunami evacuation routes and education in dealing with the Potential Mentawai Megathrust disaster. In addition, the application developed has been able to produce information on the location of the disaster, route information to the evacuation point, and safety guidance when a disaster occurs. So that people can easily find out the evacuation route to a safe place and reduce the risk impact of future natural disasters.

The Internet of Things (IoT) has made our surroundings more innovative and responsive, which has improved our lives. This research aims to provide a comprehensive overview by describing the descriptive parameters of publications, visualizing co-authorship and citation patterns, extracting the authors' keywords, and determining the impact and research performance of the IoT in education. Subsequently, this paper provides an orientation for researchers to understand better the main progress and gaps in this scientific publication. From 2006 to 2021, a comprehensive inspection of 2503 documents in the Scopus database was accomplished. Based on the findings, the number of publications increased steadily, with a hike in publication numbers in 2020. Scholars from China contributed approximately 467 of the total global publications among 103 other countries. In addition, of the other 160 outlets, Advances in Intelligent Systems and Computing was the most prolific source title. Generally, there is sustained interest and increased research in this field, apart from establishing novel methods and directions. Accordingly, an in-depth examination of the IoT in education research may assist researchers and practitioners in advancing prospective knowledge in this subject by identifying gaps.

The internet has offered marketers a new way to be more creative, resulting in more openness and transparency in marketing. The proliferation of digital media platforms and the commercial use of the internet have changed the business landscape. This study uses ScientoPy to analyze the global evolution of digital marketing research. It is grounded in the eminent Scopus and Web of Science databases. The parameters examined in this study were the number of publications, the most productive author, the analysis of the author's keywords, popular sources, and institutional information. This study discovered a rising trend in digital marketing research in both the Scopus and WoS databases. "Machine Learning" has exploded in popularity during 2019 and 2020. "Digital Marketing" is inextricably linked to "Social Media", "Big Data", "Marketing Communication", "Machine Learning", and "Sentiment Analysis", all of which gained traction in 2018 and beyond. Bucharest University of Economic Studies in Romania has become the most prolific research institution on digital marketing. The findings of this study enabled readers and future researchers to identify the primary research areas, keywords, related studies, and the most notable institutions and researchers. Besides, this study provides readers and future researchers with a global perspective on hot topics in digital marketing. It offers various analyzes for well-organized information utilization. This study also illustrates recent digital marketing research trends to inform practitioners, future researchers, and policymakers about developing digital marketing research theories and practices that merit scrutiny.

The presence of large peatland in Riau, Indonesia, could cause air pollution due to peatland fires which causes the presence of thick smoke every year in Riau, disrupting human activities. In order to monitor the air quality, in this paper, the main advantage of the Internet of Things (IoT) is the ability to transfer data over the network without requiring human-to-human or human interaction to the computer used. In this paper, we propose an air quality monitor that can display web-based information to show the temperature and air humidity, and detects CO, CO2 gases, and alcohol in real time with the help of DHT11 and MQ135 sensors, Arduino Uno and Raspberry Pie. The results show our proposed system can successfully show each parameter of the air quality on the website and make suggestions about the overall air quality level. With our proposed system, we hope the government can respond faster to mitigate the bad air quality level and give information to public about the air quality level in a faster and more accurate way.
