Police have a very important role in society. The main task and function of the police in protecting the community is the main thing to do in order to create order in society. The traffic police currently acts as a service that takes care of making a driving license (SIM). So far, SIM registration is still done manually by police officers. Therefore, the applicant must go directly to the Deli Serdang Police Traffic Unit to register and fill out the form, then the officer will enter the applicant's data individually. So it must require higher accuracy for officers when entering applicant data, then it can result in long queues for applicants and can take longer. To assist officers in managing applicant data and avoid long queues. So a website-based driving license registration information system was built. With the creation of this system, it is hoped that it can be the best alternative for the Deli Serdang Police Traffic Unit officers in improving performance, especially in terms of services for managing a driving license (SIM). So that there are no longer queues that are so long and applicant files that accumulate in the archive warehouse.

Firmware is software that resembles an operating system and embedded in the hardware. On Internet of Things (IoT) devices, the already installed firmware will not be updated for the specified time or will not even be updated at all. This is because the firmware is considered a system whose needs and functions do not need to be changed. However, in reality the firmware that is already installed and is being run definitely needs a change. The update process generally also uses conventional methods, namely by connecting devices on a computer using a cable. This method is of course not effective and efficient to do, especially if you have many devices installed and running. Therefore, in this study, an update system was created to update devices using the internet network. The update system built on this study using Over The Air (OTA) techniques and Hypertext Transfer Protocol (HTTP). In testing the update process with 3 IoT devices simultaneously, the average time needed by device 1, device 2 and device 3 is 43 seconds, 44 seconds and 45 seconds. In the QoS analysis carried out, the results obtained throughput of 100% (very good), packet loss of 0% (very good), average delay of 93,931ms (very good) and jitter of 98,948ms (medium) on the network used for updating

Precipitation is one of the most important climatic variables in many aspects of our daily lives. High rainfall intensity can cause floods, landslides, and other natural disasters. Therefore, rainfall prediction is important for predicting natural disasters, assisting farmers in production decisions, and crop harvesting. In this research, a system is built to create a rainfall prediction map using a machine learning approach and spatial interpolation algorithms in Java, Indonesia. In the field of weather prediction, the artificial neural network approach is a popular machine learning method. The artificial neural network (ANN) method is a method that has the advantage of studying connections in the previously unknown hidden layer between input data and output data through training procedures. By using the ANN method, historical weather and climate data can be applied to create a classification model and predict rainfall classes. The classification of data is determined based on the attributes of historical weather and climate data, namely temperature, humidity, air pressure, evaporation, sunlight, and the level of rainfall in the time range per day and month. From the results of the ANN modeling, it was found that the 5C month model with an accuracy value of 89% as the best monthly ANN model, and the 6C day model with an accuracy value of 81% as the best daily ANN model. After going through ANN modeling, there is a spatial interpolation algorithm that is often used to estimate rainfall, namely Ordinary Kriging. The Ordinary Kriging approach is used to reduce the estimated variance and estimate the rainfall value in the case study area. After going through Ordinary Kriging modeling, a rainfall prediction map for the next six months and seven days is made based on the coordinates as a result of the research. The results of this research are rainfall prediction maps for the next six months and the next seven days on Java Island.

Indonesia is one of the largest countries in Asia, with a very dense population. According to data from The World Bank, the human population indicator in Indonesia in 2019 increased by 270,625.57 people. It shows that population density in Indonesia is related to world problems related to household waste. The household sector contributes as the top waste producer in Indonesia. Adipura data in 2019 stated that at least household waste contributed 36%. This figure is higher than the heap of waste generated from the traditional market, which reaches 24%. The accumulation of waste that occurs without any sorting of waste makes the waste more difficult to decompose and difficult to recycle. Apart from that, the current landfill causes air pollution. Therefore, it is necessary to increase public awareness regarding waste sorting and processing to overcome these problems. We propose to make a device that can help sort organic and inorganic waste with Artificial Intelligence technology based on Computer Vision using the Eigenface method and the Internet of Things. Eigenface is a method that has the working principle of using an XML file to perform face recognition. 1. Implementation of a Computer Vision-Based Garbage Counting System Using the Eigenface Method can run well, where when the system detects an organic object, the door of the counting machine can be opened, and vice versa if it detects inorganic, the machine door is closed. Accuracy results for organic are 70% and for inorganic 75%. It is due to the lack of variation in the dataset and changes in the object's physical condition.
