Knowing Indonesia's unique geographical conditions, various disaster risks have been discovered that will occur. This disaster risk is found in areas that have special conditions, one of which is the Pancer Beach area. Where conditions are close to the beach, various disaster risks definitely arise. That's why preparedness is needed for the surrounding community which is built on an understanding of early warning. Social media representation also plays an important role in the effectiveness of Early Warning System deployment. So research was conducted which aimed to analyze the effectiveness of social media representations used in increasing citizen readiness based on an early warning system. This research method uses a qualitative approach with data collection techniques in the form of in-depth interviews, observation and analysis of documents related to early warning systems. The research results show that the effectiveness of using the media to convey information to citizens is still lacking. This research also found several challenges in the implementation process. Residents who live on the coast and in remote parts of the village have different access to the internet or social media they use. Based on the final analysis, this research recommends strategies related to media collaboration with in-depth representation regarding the dissemination of information and overall participation. So it can increase effectiveness in the process.  

. This research aims to analyze the dynamics of religious spread in the urban areas of Semarang through a spatial analysis approach using Geographic Information System (GIS). By utilizing both secondary and recent primary data, this study delineates the patterns of religious spread across various neighborhoods and districts in Semarang. Through the application of GIS, the research produces thematic maps that vividly visualize the distribution of religions in a spatial context. The analysis results reveal diverse patterns of religious spread, with some areas exhibiting a high concentration of a particular religion while others demonstrate significant religious diversity. The importance of environmental factors in shaping the patterns of religious spread is also discussed in this study. The correlation analysis between the presence of places of worship, religious educational institutions, and other environmental variables provides additional insights into the factors influencing the distribution of religions in Semarang. The conclusions drawn from this research contribute to a deeper understanding of religious diversity in urban Semarang. The implications include the potential formulation of more effective development policies, strengthening tolerance among religious communities, and creating an inclusive environment amid the complexities of social and cultural diversity in the city. This research is expected to serve as a foundation for further studies and aid sustainable decision-making at the local level.

The Map is a picture of the earth's surface that is displayed on a flat plane with a certain scale and the depiction of the earth's surface is reduced to a certain scale in the form of symbols that are selective in a certain projection system that is represented in two dimensions from a three-dimensional space. Various types of data can be described and explained in maps and provide information on the correlation of data to the geographical conditions (geospatial information) of an area which can then be used as a tool in policy formulation, in this case the customary area of ​​the Ayapo village in the East Sentani District. This research was conducted using a mapping method using spatial data based on satellite imagery from Google Earth Pro and community participation through field surveys through interviews. The data was then processed using ESRI ArcGIS software. The research was conducted in the Ayapo traditional village, Jayapura Regency, Papua Province. From the results of the information depiction carried out, it was obtained a map of the Ayapo village, a mapping of the distribution of indigenous peoples which included traditional leaders and tribal chiefs as well as a map of the structure of the customary space. Mapping also obtained the development of the ayapo village for 3 years, namely 2002, 2014, and 2021 which showed the growth of the village spread out along the coast of Lake Sentani in a linear form.

The search is often used to search for the shortest route, the Hill Climbing Method is a part of the test that uses heuristic functions. The problem that is often encountered is in the form of miscalculations in calculating the distance so that it requires long distances, costs a lot and takes a very long time. To solve this case, it can be solved by making a structure graph by looking at the city points from the two sides of the point to be passed. Using an algorithm can help make it easier to find a location and save time and travel costs that will be passed. This advantage is that all points will be obtained and checked from the right and left sides one by one so as to obtain effective and maximum results. The Hill Climbing method that will be used has the concept of a geographic information system as a guide and is used as a system for decision making. The heuristic search method is one of the methods commonly used in finding a way

Remote sensing is the science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigations Remote sensing data is of such nature and volume as to require it to be compatible with processing and outputing by computers. They are the easiest, fastest, and most efficient way to produce images, extract data sets, and assist in decision making. One special function is to assist in manipulating other kinds of data about the spatial or locational aspects of areas in the world that are the subjects of interpretation and decision making. The bulk of the data in such systems have in common a geographical significance, that is, they are tied to definite locations on the Earth. In this sense, they are similar to or actually make up what has become a powerful tool in decision making and management. The Image-Based Information System (IBIS) was developed in 1975 at the Jet Propulsion Laboratory, and is designed to be a comprehensive geographic information system that performs operations on raster image, tabular, and graphics format data, using the Video Image Communication And Retrieval (VICAR) image processing system. This was accomplished by the creation of a new VICAR-based file format for tabulating raster format geographic information over multiple data planes.
