<![CDATA[Data security is still a major issue regarding the need for data confidentiality. The encryption process using the RSA algorithm is still the most popular method used in securing data because the complexity of the mathematical equations used in this algorithm makes it difficult to hack. However, the complexity of the RSA algorithm is still a major problem that hinders its application in a more complex application. Optimization is needed in the processing of this RSA algorithm, one of which is by running it on a distributed system. In this paper, we propose an approach with a FIFO process scheduling algorithm that runs on a single board computer cluster. The test results show that the allocation of resources in a system that uses a FIFO process scheduling algorithm is more efficient and shows a decrease in the overall processing time of RSA encryption]]>

<![CDATA[Perkembangan informasi telah berkembang begitu pesat. Pesan, data, atau informasi yang begitu mudah diakses oleh setiap orang saat ini dan kebutuhan akan pengiriman informasi lewat media internet menimbulkan sebuah permasalahan baru yaitu aspek keamanan dari data itu sendiri. Sehingga muncullah sebuah metode pengamanan data yang di kenal dengan istilah steganografi. Steganografi adalah salah satu solusi untuk melindungi pesan yang bersifat rahasia yang disampaikan melalui internet dengan cara menyembunyikan pesan sehingga pesan dari proses steganografi ini tidak akan terlihat dan tidak akan menimbulkan kecurigaan. Spread Spectrum merupakan salah satu metode yang dapat digunakan dalam teknik steganografi pada media berkas audio digital dalam domain transform.Kata Kunci- Steganografi, Spread Spectrum, Audio Digital, WAV.]]>

<![CDATA[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.]]>

<![CDATA[Electrical energy is one of the necessities of human life, especially in modern society in urban areas. With a monitoring device for electrical energy consumption using IoT technology, the results of the development show that the monitoring system works well, but the results show that current and voltage measurements are still less accurate. Therefore, in this study, an Electrical Energy Analysis and Monitoring System was developed using the IoT-Based Prophet Algorithm. Data collection was obtained from electrical energy using the PZEM-004T module sensor device used at home and the energy data obtained were stored in a MySQL database. This PZEM data retrieval will appear in real-time on the Monitoring Website. The dataset was processed by implementing the Prophet Algorithm, evaluating the model and visualizing the prediction results on the analysis website. Testing using Mean Absolute Percentage Error (MAPE). For design, this system uses energy data and data retrieval time as parameters in the monitoring system for the use of electrical energy at home. Analysis of data taken from electrical energy monitoring was predicted by the model created by the Prophet Algorithm and tested with MAPE to see how accurate the predicted value is in the Prophet Algorithm model. Predictions in this study get an error value of less than 10%, namely 6.87%, which means it is very accurate in predicting the prophet algorithm at home.]]>

<![CDATA[Inside any e-commerce platform, search features are a key factor in an online business. In order to look for the desired item name, users need to type a pattern into the search feature. Inside the typing process users may make some mistypes. Based on the problem, the writer tried to create a search box as the search feature inside an e-commerce system with a capability to look for item names, even if there are some accidental mistypes inside the user's typing process. The main purpose is to reduce the possibility of empty results after a searching process due to the user’s accidental mistypes. This research utilizes Rabin Karp Algorithm in order to look for the item names. Result of this research is that the Rabin Karp Algorithm can be implemented in a website-based e-commerce, but this method is slower than SQL as a method to search item names inside the same system. It happens because Rabin Karp requires a longer process than SQL to get the similarity percentage from each comparison. This research shows that k-gram value inside the algorithm affects the overall results with a condition where greater the value.]]>

<![CDATA[General elections are a procedure for selecting leaders in a democratic country. However, during the General Election, the vulnerability to vote manipulation is one of the growing issues. Currently, e-voting systems allow hackers to control the system and tamper with election results. In addition, an election process system that is not transparent is difficult to supervise jointly. In this article, a prototype of a general election application is proposed in the voting phase, collecting vote results at each polling station and vote recapitulation. This research uses the blockchain concept with the Ethereum platform. The e-voting system applies smart contracts on the public Ethereum blockchain network. The aim is to maintain the security of election results data and maintain voter confidentiality by using an Ethereum address that represents one voter. In addition, by using the Ethereum public blockchain network, the election process can be monitored jointly. The results obtained in the research conducted in this paper show how the application of blockchain can maintain data integrity by showing the value of the data]]>
