Indonesia is a country with a population of 270.20 million people recorded at the Central Statistics Agency in September 2020. Based on the International Telecommunication Union (ITU) reported, the United Nations (UN) body, the number of world internet users in 2018 was 3.9 billion, exceeding half the world's population. Today the position of the internet continues to be significant in social, economic, and political life in a globalized world. Every year the internet continues to influence human life. Therefore we need research on forecasting the number of broadband users in the future to find out the number of users will increase or decrease as well as planning for Indonesian broadband. This forecasting research uses, using a comparison, namely the double exponential smoothing method with two different alphas and two betas, then the single exponential smoothing method with two different alphas. The double exponential smoothing method with alpha 0.2 betas 0.4 with the result that the MAD, MSE, MAPE values are smaller than single exponential smoothing with the first part alpha 0.8 and the second part alpha 0.5 and smaller than the double method exponential smoothing with alpha 0.6 betas 0.2. After getting the best value from the double exponential smoothing forecasting method, the prediction process is continued using the decision tree method, namely the ID3 algorithm for decision making every year from 2000 to 2024 to expand bandwidth or by not expanding bandwidth with the result that there are 19 years to expand bandwidth and there are 6 years for the decision not to expand the bandwidth.

In the current era of globalization, the industrial world is developing very rapidly both the service industry and the product industry in this case time is very important especially for service providers, so the company must be able to maintain its existence by limiting service time so that companies can meet targets many services to the customer. Queues can be found in several public service facilities where the community or goods will experience a queuing process from the arrival process, entering the queue and waiting, until the service process lasts until the end of service. The purpose of queuing analysis is to minimize customer waiting and service capacity cost. The model is a representation of a simplified real system. the model is a very useful tool for analyzing and designing systems. Simulation is a methodology for carrying out experiments using models from a real system by creating a simulation model of a system so it is expected to be easier to do the analysis. Promodel stands for Production Modeler is an application issued by Promodel company. This application serves to simulate or model various types of manufacturing and service systems. These manufacturing systems such as shops, conveyors, assemblies, just-in-time systems, flexible manufacturing systems can all be modeled with promodels. The time used in this case is quite good, namely at counter 1 of 49.67, counter 2 of 40.57 and counter 3 of 33.24. Because time is very important, especially for service providers, companies must be able to maintain their existence by limiting service time so that companies can meet the target number of services to customers.

Attendance is a mandatory requirement for employee attendance. There are still many who use the manual system. Of course it is not efficient, so an attendance attendance system is needed that can run to facilitate attendance tasks and activities. Attendance management is one of the systems that is currently very much needed along with the large number of human populations that must be recorded. However, most of the attendance systems currently used are still using conventional methods such as signatures to fill attendance in this way, so there are lots of loopholes for fraud that often occur. By utilizing a tool using a microcontroller. This system uses RFID RC 522 as a tool and programming language for PHP and SQL server for database management. This system uses the blackbox testing method to find out the website designed to function correctly employee attendance information technology with employee ID card documents as a website-based system there are facilities such as employee data management, room data management, attendance data management, and monthly attendance processing using cards. employee identity. It can be concluded that by using this website, the attendance process will be more efficient and can be easily monitored by leaders and the center.

It is undeniable that wireless communication technology is developing very rapidly, especially in an emergency. For example in the laboratory. The laboratory is a place to carry out practical or research activities that are supported by complete laboratory equipment and infrastructure. Therefore, it is not impossible that the complete laboratory equipment becomes an excuse for people with the aim of committing crimes. The most frequent crime in the laboratory is theft, the thieves usually take advantage of the moment when the laboratory personnel are not in the room and they can take valuables in the room without being noticed by the officers freely. Therefore our goal in this research is to improve security for laboratories with wireless communication technology methods. This technology uses a communication system named Lora equipped with ALOHA protocol based on Android to be able to monitor remotely. The test was carried out at a height of 80 cm and this study resulted in the largest RSSI value of -130 dB at a maximum distance of 600 m with a delay of 29 seconds. Packet loss is affected by distance, so packet loss or data loss will be higher at longer distances.

One of the causes of traffic accidents is the vehicle factor caused by the brake system that is not functioning properly. Brakes are a very important component in a vehicle, its function is to reduce the kinetic energy of the vehicle where the safety of the driver is very dependent on this component. Materials are very important role in the design of disc brakes, the main factor in the braking process is friction, and each material has its own friction coefficient. In the automotive industry there are many types of disc brake materials, so it is necessary to conduct a more indepth study on the effect of the disc brake material to determine the deformation, stress and strain that happen during the braking process. The method we used is to design a disc brake on solidworks and simulate it in ansys 19.2 software to find the structural transient values of gray cast iron, aluminum alloy, stainless steel, and titanium alloy materials. The result of this research is a data on the transient structural disc brake of the Vario 125 CBS motorcycle with the highest maximum total deformation happens in the gray cast iron material of 8.4965 mm. For the maximum value of equivalent elastic strain, the highest happens in aluminum alloy material at 0.012275 mm/mm. For the highest maximum equivalent stress value happens in stainless steel material at 1494.3 Mpa.
