Risa Naili Fitriana — 2022-12-31

The development of technology is followed by a large amount of data. Not all of the data is presented to the general public, some data are strictly kept confidential because of certain interests. This study aims to test the encryption and decryption of text data (with *.txt format) to maintain confidentiality and compare the performance of the AES algorithm with RC4. This study uses the AES and RC4 algorithms with a key length of 256 bits using CrypTool 2 for encryption and decryption processes. The result of the first trial is that the encryption and decryption test of the AES algorithm on text data results in a different ciphertext size from the original text data. While the second trial was carried out by encryption and decryption of the RC4 algorithm on text data, resulting in the same ciphertext size before the simulation process was carried out. So from this research, the RC4 algorithm produces a smaller ciphertext size than using the AES algorithm.

Online learning methods can indeed be an alternative solution to the pandemic situation, but that doesn't mean it's without risks. Cyber risks can vary widely, ranging from cyberbullying, victimization, game addiction, privacy concerns, harmful content, and also eye health problems. These risks can cause serious problems, especially for children aged 5 to 12 years. One of the guidelines for the parental involvement model to assist the healthy use of information technology is ABC's. ABC is an acronym for Age-Appropriate Access, Balance, and Content Restricted. In the ABC's model, specific recommendations and examples are given on how to set boundaries so that the use of technology remains healthy and useful. On the other hand, the Digital Quotient (DQ) Institute provides a micro-certification system called the DQ Micro-Badge (DQ MB) which is listed in the IEEE 3527.1-2020 standard. DQ MB is used to assist in the assessment of a person's digital skills according to the Global Standards. This study measures the relationship between ABC's parenting method and the achievement of DQ MB Balanced Use of Technology. Respondents used are parents who have children aged kindergarten - elementary school in the city of Surabaya. From 379 respondents' data, it was analyzed and obtained the fact that parenting using ABC's approach is proven to affect the level of digital intelligence based on the DQ MB Balanced

Bayu Nugroho — 2022-12-31

Word embedding is a technique to represent sentences in vector space. The representation itself is carried-out to build a model that would suffice in representing a particular task related to the use of the sentence itself, for example, a model of similarity among sentences/words, a model of Twitter user connectivity, and demographics of tweets model. The use of word embedding is a handful to the sentiment analysis research because it helps build a mathematical-friendly model from sentences. The model then will be suitable as feeds for the other computational process.
