Abstract

Gytech Indosantara Mandiri Ltd. in the last few years experienced many Cybercrime attacks on the Web Server which caused many moral and material losses. Therefore, it is necessary to consider ways to fight and prevent attacks on the webserver. One way to fight and prevent attacks is to use the Attack Signatures method by using ModSecurity and fail2ban as a Web Application Firewall (WAF). ModSecurity is used to detect and prevent the occurrence of Cyber Crime in the Http and https services. Whereas Fail2ban is used to prevent Bruteforce attacks on ssh, FTP and telnet services. Modesecurity, which acts as a Web Application Firewall (WAF) will send logs to Fail2ban when exploits occur on the Web Server. Meanwhile, Fail2ban will block the Attacker's IP address so that both can be used as a Web Application Firewall or can be used as layer 7 network security.

Abstract

In the industrial 4.0 era, there have been many developments in daily equipment that have been transformed into more sophisticated tools both in terms of how they are used, the efficiency of their work and the quality of the results obtained due to the digitization process that is easily accessed by many people. Therefore, As the early step, the paper discusses the computational modeling in the automatic cooking methods, namely the smart roaster system. The cooking method in the form of granules by using a roasting process, which generally utilizes heated sand, is interesting to learn since there are two mechanisms of heat propagation from the pan to the food object, namely the mechanism of heat propagation by conduction and radiation, but in this study, the heat propagation due to temporary convection was ignored. The first mechanism is accommodated by Fourier's Law, while the second is by Stefan-Boltzmann's Law. For simplification, the system is discussed in one dimension with the same grain size, but the object can have a different size. The composition of the pan walls, grains of sand, empty space, and food objects can be randomized so that various configurations can be created. Discussed how the process of heat propagation can occur in the roasting process and also radiation to the surrounding space on the top of the sand surface. The numerical analysis method is used with the finite difference method and the Matlab programming language for simulation.

Abstract

Health monitoring reports against COVID-19 suspect must be presented every day at 7 o’clock in the morning and 7 o’clock at night. In this report, every patient vital signs must be monitored in order to prevent a potential decline in the level of health from the patient. One of the symptoms observed in this monitoring is a change in body temperature. This monitoring should be carried out without touching the patient’s skin to reduce potential risks of droplets that contain the virus from spreading. This work proposes an idea related to non-contact temperature monitoring which is suitable to use in this pandemic condition. This idea realization process by building a data storage terminal for body temperature scans that is mobile, cheap and has a large storage capacity. This mobile terminal is an integration of the MLX90614 a temperature sensor series, Arduino UNO and Telegram apps. In addition, the communication process between the sensor and the Telegram apps utilizes the GPRS cellular network services. Before arriving at the Telegram apps, this data will pass through gateway site which acts as a collector and relay. In the process of sending the temperature data is then converted into two body temperature categories, normal temperature and abnormal temperature. Based on the trial results that have been carried out, this system consumes 2A of current and 5V of voltage. The communication time duration between the temperature data acquisition system and the collector site is 28 seconds. While the length of time for sending the data from the collector site to the Telegram apps is 8 seconds

Abstract

Abstract Technology implementation in the marketplace world has attracted the attention of researchers to analyze the reviews from customers. The Klik Indomaret application page on GooglePlay is one application that can be used to get information on review data collection. However, getting information on consumer’s opinion or review is not an easy task and need a specific method in categorizing or grouping these reviews into certain groups, i.e. positive or negative reviews. The sentiment analysis study of a review application in GooglePlay is still rare. Therefore, this paper analysis the customer’s sentiment from klikindomaret app using Naive Bayes Classifier (NB) algorithm that is compared to Support Vector Machine (SVM) as well as optimizing the Feature Selection (FS) using the Particle Swarm Optimization method. The results for NB without using FS optimization were 69.74% for accuracy and 0.518 for Area Under Curve (AUC) and for SVM without using FS optimization were 81.21% for accuracy and 0.896 for AUC. While the results of cross-validation NB with FS are 75.21% for accuracy and 0.598 for AUC and cross-validation of SVM with FS is 81.84% for accuracy and 0.898 for AUC, while there is an increase when using the Feature Selection (FS) Particle Swarm Optimization and also the modeling algorithm SVM has a higher value compared to NB for the dataset used in this study.
