Impact Analysis of Malware Based on Call Network API with Heuristic Detection Method
Malware is a program that has a negative influence on computer systems that don\u27t have user permissions. The purpose of making malware by hackers is to get profits in an illegal way. Therefore, we need a malware analysis. Malware analysis aims to determine the specifics of malware so that security can be built to protect computer devices. One method for analyzing malware is heuristic detection. Heuristic detection is an analytical method that allows finding new types of malware in a file or application. Many malwares are made to attack through the internet because of technological advancements. Based on these conditions, the malware analysis is carried out using the API call network with the heuristic detection method. This aims to identify the behavior of malware that attacks the network. The results of the analysis carried out are that most malware is spyware, which is lurking user activity and retrieving user data without the user\u27s knowledge. In addition, there is also malware that is adware, which displays advertisements through pop-up windows on computer devices that interfaces with user activity. So that with these results, it can also be identified actions that can be taken by the user to protect his computer device, such as by installing antivirus or antimalware, not downloading unauthorized applications and not accessing unsafe websites.
 
On the flips for a synchronized system
It is shown that if an infinite synchronized system has a flip, then it has
infinitely many non-conjugate flips, and that the result cannot be extended to
the class of coded systems
ISOLASI DAN UJI AKTIVITAS ANTIBAKTERI EKSTRAK DAUN TUMBUHAN GARCINIA LATERIFLORA BLUME
ABSTRAKSenyawa alkaloida yang diduga adalah alkaloida turunan fenilalanin telah diisolasi dari daun Garcinia lateriflora Bl. Isolasi dilakukan menggunakan kromatografi kolom dengan pelarut diklorometana 100%. Analisis senyawa hasil isolasi dilakukan secara fitokimia dan KG-SM. Hasil uji hayati menunjukkan bahwa ekstrak etil asetat memiliki aktivitas antibakteri terhadap bakteri Escherechia coli dan Staphylococcus aureus pada konsentrasi 20% dengan diameter zona hambat yang dihasilkan masing-masing adalah 10 mm dan 7,75 mm.Kata Kunci: Garcinia lateriflora Bl., Antibakteri, Escherichia coli, Staphylococcus aureusABSTRACTAlkaloid coumpound proposed phenylalanine derivative alkaloids have been isolated from the leaves of Garcinia lateriflora Bl. Isolation was performed using coloum chromatography with 100% dichloromethane solvent. Analisis of isolated compounds carried out phytochemical and GC-MS. The results of antibacterial activity showed that the ethyl acetate extract has antibacterial activity againtst bacteria Escherechia coli and Staphylococcus aureus at a concentration of 20% with a diameter of inhibition zone producted amount 10 mm and 7,75 mm.Keywords: Garcinia lateriflora Bl., Antibacterial, Escherichia coli, Staphylococcus aureu
