Control and monitoring systems that use the Internet-of-Things (IoT) can be found in everyday life, for example, in smart home applications, smart transportation, and smart cities. IoT-based monitoring of environmental conditions both indoors and outdoors is generally carried out to reduce the risk of unwanted events. One example of an unwanted event is a fire. Fires can occur in houses, office buildings, rice fields, or forests. In order to help provide early warning of a flame that can cause a fire, this study aims to design and implement an IoT-based fire detection and warning system using the NodeMCU ESP8266 and a flame sensor. The sensor used is an infrared sensor that will detect infrared light radiation coming from a fire. The test results show that the system successfully detects the presence of fire up to 50 cm from the fire sensor and can be monitored via thinger.io. Additionally, notifications from thinger.io via e-mail and Telegram to users were successfully executed.

Currently we cannot escape the influence of information technology. Because like it or not, the development of science and the application of technology is experiencing an increasingly rapid increase, especially in every work environment such as business practitioners.Computer/information technology is the technology that is most widely used in various agencies, both government and private. The rapid development of technology over time means that human work can generally be completed quickly. Technology is a tool that is often used in human activities. The role of technology today makes information processing easier because processing is necessary so that the resulting information can be useful for its users. Competition in the business world requires developers to find a pattern that can increase sales and marketing of goods, one of which is by utilizing transaction data. The availability of abundant data, the need for information to support decision making to create business solutions, and infrastructure support in the field of information technology are the reasons for the birth of data mining technology. Problems that occur at UD. Martua is lacking in reviewing the products being sold, what products consumers need and less effective data storage. With data mining, it is intended to provide real solutions to UD. Martua can find out which items are selling well and which items are not selling well, then can compare sales from year to year to become an effective medium for developing sales at UD.Martua. In grouping sales data, the fields used are item name, quantity purchased, quantity sold for 1 week, then the data will be processed with the k-means clustering algorithm. The final result with 20 grouping data samples was the final result with 2 clusters, namely, cluster 1 (C1) with 10 best-selling items, cluster 2 (C2) with 10 non-selling items. With data mining using the K-Means algorithm, losses for UD.Martua..speeding up decision making to restock goods that are selling well so that consumers who want to buy don't have to wait long. Providing information from sales data to find out what causes profits or losses at UD.Martua. Providing convenience for UD.Martua in determining which products are selling and which are not selling so that there is no accumulation of goods that are not selling and resulting in losses for UD.Martua.

Background: A traffic accident is an unexpected and unwanted road traffic event which is difficult to predict when and where it will occur, involving at least one vehicle with other road users or due to negligence in driving a vehicle, be it a car or motorcycle which can cause death, disability, serious injury or minor injury. Within the territory of Indonesia itself, every hour has an average of at least three people who die as a result of the accident with many causal factors such as the human factor itself, which is around 61%, then the vehicle factor is 9% and environmental factors and infrastructure contribute as much as 30%. Case Description : We report a case of a traffic accident with multiple trauma. This traffic accident involved 2 motorbike riders who were traveling at maximum speed so that they collided with a truck that was stopped at a red light in Makassar City, South Sulawesi, on Thursday 15 June 2022 at around 01.00 WITA and caused the two motorbike riders to die. The motorbike that was traveling at high speed suddenly stopped and hit the back of the truck, as a result the body moving at the speed of the vehicle suddenly experienced a deceleration, causing multiple trauma to several regions or organs of the body. The effects on the victim's corpse varied in the form of head injuries, open wounds, and fractures to several bones. Conclusion : Forensic examination is very useful to determine the cause of death, mechanism of death, and nature of death. In the medical report of a traffic accident, the forensic doctor can explain his findings in the form of a post mortem et repertum.

Education is the main foundation in community development and human resource development. In the context of higher education, the quality of the learning process and lecture management greatly affects student success. One aspect that has a significant impact on the learning process is student attendance management. Traditionally, recording student attendance is done manually by using a physical attendance list that must be filled in by students and signed by lecturers. Although it has been used for a long time, this method has a number of limitations that need to be overcome. In the rapidly evolving digital era, we have access to technology that can simplify and improve student attendance management. The use of information technology can provide a more efficient, accurate, and practical solution in recording student attendance. The app was developed using MIT App Inventor, a platform that makes it easy for users to create Android apps without in-depth programming knowledge.  

Every motorized vehicle driver must comply with traffic rules and regulations. This aims to ensure the safety of motorized vehicle drivers and other road users. But because of the increase in the number of motorized vehicles, the accident rate continues to increase every year and the number of victims continues to increase, which is one of the bad factors in the increase in the number of motorized vehicles in Indonesia. This factor occurs due to the driver's human negligence, starting from lack of sleep, fatigue, carelessness, and low rider discipline. The police enforced it with fines but it was still frequently violated by motorists. Therefore, the existence of electronic tickets (E-TLE) using CCTV surveillance cameras, is expected to help reduce violations and reduce the level of road accidents.
