The development of information and communication technology is increasingly sophisticated, especially in the field of networks. This development is closely related to the internet which is one of the most popular information providers today. The increasing need for information will demand fast access to get the latest information, one of which is the most dominant influencing the speed of access to a particular website is the service provider. Therefore it takes a server that has good quality and performance or has many servers so that it is not burdened on one server. Application load balancing is one of the right solutions to overcome this problem. The load balancing application will share the network load and avoid overloading one of the servers. The load balancing application method used is round robin with stickiness. When one server crashes, the load balancing application will automatically redirect requests to another server that is still functioning, so that the website can be accessed..

In the development of increasingly advanced technology, the security of a data is something that must be considered in maintaining the confidentiality of information. The data contained in the file contain information that can only be known by certain parties. In general, files are stored or shared into a storage that can be accessed using the internet or known as cloud storage. There are ways to secure information on a file so that it cannot be hacked or read to unauthorized parties, namely by using cryptographic methods. Cryptography is a technique to improve the security aspect of information. Cryptography is used to convert information that can be read into unreadable and return an information that was previously unreadable to be legible. In this study cryptography uses the Advanced Encryption Standard (AES) algorithm and Google Drive cloud storage services.

The risk assessment of air pollution is an essential matter in the area of air quality computing. It provides useful information supporting air quality (AQ) measurement and pollution control. The outcomes of the evaluation have societal and technical influences on people and decision-makers. The existing air pollution risk assessment employs different qualitative and quantitative methods. This study aims to develop an AQ-risk model based on the Nested Monte Carlo Simulation (NMCS) and concentrations of several air pollutant parameters for forecasting daily AQ in the atmosphere. The main idea of NMCS lies in two main parts, which are the Outer and Inner parts. The Outer part interacts with the data sources and extracts a proper sampling from vast data. It then generates a scenario based on the data samples. On the other hand, the Inner part handles the assessment of the processed risk from each scenario and estimates future risk. The AQ-risk model is tested and evaluated using real data sources representing crucial pollution. The data is collected from an Italian city over a period of one year. The performance of the proposed model is evaluated based on statistical indices, coefficient of determination (R2), and mean square error (MSE). R2 measures the prediction ability in the testing stage for both parameters, resulting in 0.9462 and 0.9073 prediction accuracy. Meanwhile, MSE produced average results of 9.7 and 10.3, denoting that the AQ-risk model provides a considerably high prediction accuracy.
