Abstract

This study discusses the methods of encoding and decoding the base64 cryptographic algorithm. The term encoding means a process of converting plaintext into ciphertext. While decoding is a term that means the process of turning ciphertext back into plaintext. In general, classical cryptography has been abandoned because of its logic which can be easily solved, so now it has switched to modern cryptography which operates in bit-binary mode which is formed from ASCII code. The base64 algorithm is a form of modern cryptography which is included in the modern type of block cipher cryptography. This study aims to obtain a comparison between 3 types of tools in carrying out a cryptographic encode and decode process on the base64 algorithm. The 3 types of tools include the Base64 Python Program, Bash Base64 Kali Linux, and CyberChef which are online tools. This type of research method uses qualitative methods because it tends to use analysis in research. Where the results of the first comparison are used to make it easier to see the accuracy of the encoding and decoding processes and the results of the second comparison are used to compare in terms of time efficiency when encoding the three tools using 1,000 words which will continue to be added by 4,000 words, up to a total of 9,000 words . These words are taken using dummy text (lorem ipsum).

Abstract

Along with current technological developments, security for data information residing on websites is very vulnerable to crimes in the internet world such as attacks on security holes in the database layer or often known as SQL Injection. SQL Injection attack is a method to insert SQL commands as input through an application, namely Kali Linux, in order to gain access to the database. This attack can find out usernames, passwords, and other data that is in the database. So that the SQL Injection attack is one of the most popular attacks and is often used to take advantage of security holes in the system because of how easy it is to use it. This study aims to test the level of effectiveness of SQL Injection attacks using the tools in it against a website. Testing the effectiveness is done by doing a comparison between the three tools that are in SQL Injection. The results of the research on the effectiveness of the tools in SQL Injection are the accuracy of database search times and the accuracy of information from the database.

Abstract

The fact that social media is so unreliable does not prevent Twitter users from using the service. Twitter is one of a few social media platforms that allows users to engage in conversation, share information, or even reveal their true identities, such as when discussing a movie's plot. A tweet or comment about a movie that is posted on Twitter may be viewed as a tool to improve the quality of movie production. To understand this, one can use sentimen analysis to categorize as either negative or positive by comparing the Naive Bayes and k-Nearest Neighbors algorithms to determine which one is the most accurate. The results of the two algorithms' comparative testing reveal that the Nave Bayes algorithm has a higher rata-rata accuracy of 99.63% with an AUC of around 1.000, while the K-NN algorithm has a higher rata-rata accuracy of 99.25% with an AUC of 1.000.

Abstract

Myers-Briggs Personality Type (MBTI) is a popular personality metric that uses four dichotomies as indicators of personality traits. This study uses a public dataset from Kaggle, namely the Myers-Briggs Personality Type Dataset, the model tested is several machine learning classification models with the help of imlearn under-over sampling techniques for classifying MBTI personality types. This study aims to classify the Myers-Briggs Type Indicator (MBTI) personality type based on text from user posts on the social media platform Reddit. The dataset used in this study consists of around 8,000 posts collected from the MBTI subreddit. Several text processing methods such as tokenization, punctuation removal, and stemming are used to process the raw data before it is entered into the model. The experimental results show that the LSTM model using Adam's optimizer and a learning rate of 0.01 produces good performance with an accuracy of 80.73 compared to other machine learning models. In addition to the LSTM model, XG Boost is also a classification model with the highest accuracy based on 16 personality types producing an accuracy of 60.09 and Logistic Regression with the NS dimension as the best accuracy value of 87.21%.

Abstract

In general, at the puskesmas there are many activities such as treatment of diseases, health checks, laboratory tests, immunization of toddlers, and others. The large number of patients causes much problems in archiving data on patient visits for treatment, as well as patient medical records. Meanwhile, the drug data collection is made manually, by conducting a stock of names every month, to check how many drugs have been used by the Puskesmas. After that, at the end of each month, the person in charge of the pharmacy does a recapitulation but there is a discrepancy between the checking results and the remaining stock. To overcome this manual process, a desktop-based application was created to build a system to simplify all the necessary processes, such as the patient visit archiving process which functions to report patient visit data, process medical records directly on the system to make it easier to store data, the process of calculating drug stock. available and do not need stock of name manually. This health service application is made using Microsoft Visual Basic 2010 which stores patient data, medical records, medical personnel, and available drugs so that it can make it easier for medical personnel to record, search, report patient visit data, medical records and facilitate stock calculations drugs in accordance with applicable health service operational standards.

Abstract

The recording and processing of population data is the responsibility of the district/city government, where the implementation begins with the sub-district as the spearhead of population registration. These services need to be done quickly and precisely to get information. But in reality, data processing at the Department of Population and Civil Registry is still done in the form of books or archives, so errors often occur and even data archives are lost or damaged because there are too many records. Therefore, a web-based information system is researched and analyzed which is expected to be able to dynamically store population data and be able to process and create population reports anytime and anywhere without having to take a long time and effort. The result of the research is the success of creating a website that functions as a Population Information System at the Department of Population and Civil Registry, with this website it will be able to assist in managing population data and make it easier to search data and also make population reports. Making a Population Information System at the Population and Civil Registry Office is web-based and is made using the PHP and MySQL programming languages so that the system can be accessed anywhere and anytime.

Abstract

Clustering is a data mining method that is widely used to group data based on similarity. This clustering process can be used to streamline data so as to facilitate the data ranking process. The purpose of this study was to make comparisons of distance measurements on the K-Means and TOPSIS methods to select students who would take part in industrial visit activities. The method used in this study is the K-Means Algorithm to carry out the clustering process whose results will be processed using the TOPSIS method, both of which use Euclidean, Manhattan and Minkowsky Distance. Based on the clustering process, there were 21 respondents who were eligible to be included, then with TOPSIS a ranking process was carried out. Of the three distance measurements used based on the Pearson Euclidean distance correlation test, the highest results were 0.992, Manhattan 0.982 and Minkowsky 0.980, with ratings one, two and three respectively. For the Spearman correlation, Eculidean is 0.972, Manhattan is 0.982 and Minkowski is 0.955. Thus, Euclidean distance gives the best correlation results, while for alternatives, Manhattan distance or Minkoesky distance can be used.
