Abstract:
Information technology's hardware and software are constantly evolving. The rise in cybercrime cases is consistent with this trend. While operating systems can be hacked, personal data can be stolen and encrypted, making it impossible for users to access the information. Cybercriminals are using social media data to target personal information currently. Users' usernames, passwords, and other personal information can be stored in a device's memory, as well as browser cookies. Pre-analysis, analysis, and post-analysis are the three stages of the research process. "Live Memory Acquisition" is the proper method for obtaining data from a device's memory. There is digital evidence in the form of an email address, a password, Facebook, and PayPal accounts as well as a link URL discovered in the analysis of the results of the acquisition of artifact one. The results of the artifact 2 acquisition did not reveal any passwords. There was no evidence of email or Facebook passwords in the analysis of artifact 3 acquisition results, but the overall data test results showed that the total number of test results on artifact 1 was 100%, 57.14% on artifact 2, and 71.42% on artifact 3.

Abstract:
Based on data on the results of oil palm production in PTPN IV Marihat displays several locations with fruit yields that vary in number. For this reason, grouping of potential fruit-producing locations is needed to know which locations produce large or small numbers of palm fruit. The production sharing is usually done based on the location or block of harvesting oil palm fruit. Therefore, a method is needed to facilitate the grouping of fruit producing locations. With the K-Means clustering approach, the division of location groups can be done based on harvested area (Ha), production realization (kg) and harvest year. In this research, clustering of potential fruit-producing areas was carried out using the K-Means algorithm. By using K-Means aims to facilitate the grouping of a block with a lot of fruit production, and low. The result of this research is that C1 (highest) is 14 Harvest Block data, and C2 (lowest) is 11 Harvest Block data.

Abstract:
With the development of advances in computer technology today, most companies and organizations need a decision support system based on information systems, where the information is generally stored in the form of documents / text that is not structured. In this regard, a system for text management that is integrated with the decision support system is needed. One of them is the use of text data classification for anthropometric case studies of several samples. Anthropometry is a measurement of a person's body dimensions. The object of research is gender, first name, and height of a person. The research aims to determine the ratio of the number and height probability level of the number of men and women based on the input into an application using the Naïve Bayes Classifier method. The implementation design uses the Python programming language. The results showed that the height classification data frequency of women was more than the height classification data for men. And the number of height probability of a woman's body is greater than the number of height probability of a man's body.
