Abstract

This study uses a classification system in managing its data. In classification there are several methods provided, one of which is the decision tree method with the C4.5 algorithm this method means a decision tree where the structure is the same as a flowchart where each node signifies an attribute test, each branch presents the test results and the leaf node represents the class or class distribution. The data used is the data of Lake Poso Tourism visitors from 2009 to 2020, then the method used in this study is divided into several stages, namely the data being studied, analyzing the data, transforming data and designing a decision tree with the C4.5 algorithm. The results achieved from this study are that the number of visitors more than 28,984 has a description of "Much" which is dominated by local tourists, while the value with the name "Less" is in foreign tourists. This is one of the important points in determining the right strategy for developing tourism in Lake Poso.

Abstract

Disk encryption technology is something very useful in securing data. On the other hand, disk encryption can be used by criminals to hide the digital evidence. The information in the disk will be very useful for the investigation, but if the disk on the computer evidence encrypted then it will hamper the investigation process. The conditions will certainly be a challenge for investigator cybercrime to be able to find the disk encryption key, especially if the perpetrator did not cooperate in the investigation process. The analysis of the image memory to get the encryption key will be helpful in the investigation. In the overall memory activity on the computer evidence will be recorded, using a live image memory dump on the computer evidence, the decryption keys can be recovered. This paper will discuss about forensic analysis to getting the disk encryption key on the dm-crypt is used to encrypt the disk on Linux operating system and prove that through forensic image memory on a live memory dump, key dm-crypt disk encryption can be found with a success percentage of 80%. On this paper the research will be focused on the Linux operating system with dm-crypt function to full disk encryption.

Abstract

In today's online-based era, the use of websites in carrying out patient registration procedures is very useful. Dental Clinic Dentika is one of the dental clinics located in the Tangerang area and has quite a number of patients. In the procedure for registering patients for examination, they still use a manual system, where patients come directly and wait in line for the examination. This is deemed ineffective because long lines can occur at a certain time. This web-based online patient registration is to make it easier for patients to register themselves when they are going to take medication or dental care without having to come to the clinic first. Another advantage is that it makes it easier for clinical administrative staff to serve patient registration, increases time efficiency in terms of patient care and facilitates patient data management. The User Centered Design (UCD) method is one of the right methods to solve the problem of patient registration at the Dentika Dental Clinic. This method looks at the needs of the user or users in designing an information system. The result of this study is a website that can be accessed by patients to register for the examination

Abstract

Fuel oil is the main requirement when people want to drive, one of the vehicles is an automatic motorbike which is widely used by the community. There are many fuels at the gas station, namely premium, pertalite and pertamax. In choosing community fuels, there are still many things to consider, both in terms of quality, price, fuel efficiency, and others. From these various considerations, people must be confused about which one is suitable for their needs. For this reason, there is a DSS (Decision Support System) for selecting motorcycle fuel to assist in finding the appropriate fuel. This system was created using the MADM (Multiple Attribute Decision Making) method to find alternatives to various criteria, including the SAW (Simple Additive Weighting) method to find a rating for each weighted criterion. In the SAW method, the largest rating is the result of alternative choices. The calculation result of the method is if the selected alternative meets the predetermined criteria. In this study, the results of the calculation simulation obtained through the survey are pertalite fuel with the final rating of 0.718, while Pertamax is 0.716 and premium is 0.665
