<![CDATA[Undoubtly that social media has been used to exchange idea easier and faster. That increasingly widespread exchange of data on social media boosts the data growth and generates various structures of data. University can benefit this large of data by gaining knowledge related to topics discussed by social media users. By gaining this knowledge, university can define which information must be disseminated by analyzing the topic that most of users discussed on social media. However, the diversity of data structures spread on social media complicates the process of obtaining this knowledge. This can be overcome by analyzing social media data using the Natural Language Processing method. This study suggests a framework for text classification using topics in the form of Indonesia language that is spread on social media. The data analyzed in this research are social media data on Facebook and Twitter at the XYZ University. This analysis was carried out by conducting experiments using applications from previous research]]>

<![CDATA[The process control of the parking cross which is manually still has weaknesses. This weakness can be exemplified by the obligation to place someone to guard the bar so that it can be opened and closed when guests come in and out. And on the other hand the guards cannot memorize the faces of the guests who are allowed to enter through the bar. A well-structured parking system that is able to offer a variety of solutions to existing parking problems is the most needed parking system today. RFID (Radio Frequency Identification) can be the answer to build this system. In this research, a parking barrier lock system design automatically uses RFID. RFID is a technology to identify an object automatically (Automatic Identification System). The process of transferring data on RFID can occur without having to touch (contactless) between devices. RFID consists of 2 main components, namely a tag and a reader. The RFID Reader is used to read the ID numbers on the RFID card, and the Arduino Uno is the controller. With the development of a parking system using RFID, changing the manual parking system to a computerized system that provides a lot of facilities and controls that are more effective and efficient.]]>

<![CDATA[Parking problems such as effectiveness, parking efficiency are parking problems that have occurred in manual parking systems. Therefore, it is necessary to have a well-structured parking system capable of offering various solutions to existing parking problems. One solution to building this system is to create a parking monitoring system based on IoT. The Parking System Design aims to design an IOT-based microcontroller that can inform and direct car drivers to an empty parking area and to determine the availability of parking slots, especially in large and multi-storey parking lots.. This design has several common parts that are used, namely NodeMCU ESP8266, IR Obstacle Sensor, LM2596, Servo Motor, Smartphone, Adapter. In this design, the distance on the sensor is less than 5cm, indicating that the parking slot is filled, while the servo motor will control the entrance and exit bars of each vehicle that wants to enter with a delay of 2 seconds. The smartphone will receive data from the sensor to display the number of filled vehicles and empty slots.]]>

<![CDATA[Travel from one place or location to place others taking into account the path or route the shortest one to go through in the case of traveling can be solved by the ant algorithm method. With the limited number of sales and efficiency in the medical equipment sales job, it is not uncommon for workers to do this experiencing various problems in the visited clients at the hospital, one of them the simple problem that is experienced is a problem time and cost efficiency in traveling. Not to mention the added limitations of the company's budget and time. and workers wish to visit multiple locations all at once. These time and cost efficiency issues are frequent happens because you don't know which path to go they traveled by selecting the best route by sales employees can at least minimize costs expenses for transportation and time wasted on Street. And the number of places you want to visit at various locations with different mileage make a decision which location want to go to. Ants algorithm find the most optimal path of all probability of the path the ant has taken with leaving pheromones in excess a lot. compared to paths that are not optimal. Result research shows that the optimal pathway with most pheromones are location route paths the shortest and optimum hospital.]]>

<![CDATA[Data mining is the process of finding patterns from large data sets using description, estimation, prediction, classification, clustering and association techniques. One of the mininng data techniques used to group is the Agglomerative Hierarchical Clustering algorithm. The process of grouping data using Agglomerative Hierarchical Clustering aims to group objects based on the distance between the two clusters. There are several methods on Agglomerative Hierarchical Clustering algorithm namely Single Linkage, Average Linkage and Complete Linkage. In this study, the authors used the Average Linkage method. By using average linkage the author is interested to conduct research on infant immunization data in Kotajuang Health Center and Gandapura Health Center in Bireuen Regency. Immunization is the process to make a person immune or immune to a disease. This process is carried out by administering a vaccine that stimulates the immune system to be immune to the disease. The purpose of this study was to look at the grouping of infant immunizations based on 3 data variables namely gender, address and type of immunization. From the results of the study, the results were obtained for one of the groups consisting of 3 villages, namely Pante Sikumbang Village, Palohme Village and Ie Rhop Village. It has a male infant immunization rate of 54% and a female infant immunization rate of 77%. The information shown is that awareness of immunizations for baby boys and baby girls in this group "has started well".]]>

<![CDATA[Disasters such as earthquakes, tsunamis, floods and others always cause losses in the form of material, psychological can also cause casualties. To avoid the occurrence of greater losses, an early disaster warning and information system is needed to provide opportunities for self-rescue so that losses can be minimized. The basic concept of the Internet of Things (IoT) "wherever, whenever and however" and connected to the internet is very suitable when applied to detect and early warning of natural disasters. This tool will monitor the water level using a water level float sensor and detect vibrations with the SW-420 vibration sensor module. when the water exceeds the height of the water level sensor, the data will be processed by the Arduino programmed using the Arduino IDE then the data is sent to the NodeMCU 8266-12E to send data notifications to the user. The reading results can be seen on the Telegram smartphone application.]]>
