Abstract Data aggregation is the process of efficiently collecting and transferring sensing data to a destination; it aids in the methodical and cautious utilization of sensor network resources. In the same way, when opening aggregated data that is free of noise and errors, the accuracy and efficiency of the data received improve. For this to happen, the data must flow to the destination in the most precise manner and in the shortest possible time by understanding the area's circumstances and addressing the immediate demands of the site where the sensors are positioned. This necessitates precise algorithms that eliminate errors and noise in the sense of data before aggregating it. The network used the ACNM technique – accurate data aggregation created by neural networks and data classification processed through machine learning in wireless sensor networks. We employ machine learning as part of artificial intelligence that learns from data. Following that, it can detect errors and noise in that Data in stages, reduce them, process them in a neural network model, and finally aggregate them to deliver the most accurate data to the destination. When data was provided using this ACNM protocol, the results showed that it arrived at its destination with the least delay.

Indonesia is a country located in the equator, which has beautiful natural. It has a mountainous constellation, beaches and wider oceans than land, so that Indonesia has extraordinary natural beauty assets compared to other countries. Behind the beauty of natural it turns out that it has many potential natural disasters in almost all provinces in Indonesia, in the form of landslides, earthquakes, tsunamis, Mount Meletus and others. The problem is that the government must have accurate data to deal with disasters throughout the province, where disaster data can be in categories or groups of regions into very vulnerable, medium, and low disaster areas. It is often found when a disaster occurs, many found that the distribution of long-term assistance because the stock for disaster-prone areas is not well available. In the study, it will be proposed to group disaster-prone areas throughout the province in Indonesia using the k-means algorithm. The expected results can group all regions that are very prone to disasters. Thus, the results can be Province West java, central java very vulnerable categories, provinces Aceh, North Sumatera, West Sumatera, east Java and North Sulawesi in the medium category, provinces Bengkulu, Lampung, Riau Island, Babel, DIY, Bali, West Kalimantan, North Kalimantan, Central Sulawesi, West Sulawesi, Maluku, North Maluku, Papua, west Papua including of rare categories. With the results obtained in this study, the government can map disaster-prone areas as well as prepare emergency response assistance quickly. In order to reduce the death toll and it is important to improve the services of disaster victims. With accurate data can provide prompt and appropriate assistance for victims of natural disasters.
