Abstract

Transposition has a very important role in the translation because the structure of the source language is often different from that the target language. By applying the transposition, then the translator can customize the translation in the target language with a more flexible and easier to read and understand. Without applying the transposition, a translation will be stiff and could even have no meaning because the structure is not adapted to the target language, and it may be very confusing for readers. This study aims at 1) describe the types of transposition that occur in a book translation Bilingual Science Biology for Junior High School Grade IX.

Abstract

Employee performance appraisal is a way of evaluating employee work performance with a set of objective benchmarks that are directly related to one's duties and are carried out regularly. Employee performance appraisal is carried out by the Pontianak City Office of Communication and Information with conventional techniques so that the presentation of employee performance reports is not timely, inaccurate and less than optimal. The author intends to conduct research to solve the problems experienced by the Office of Communication and Information Pontianak by designing employee performance appraisal information systems using UML (Unified Modeling Language) modeling consisting of diagrams use cases, class diagrams and sequence diagrams. Data collection techniques are done using descriptive methods to collect data, analyze and interpret it. As well as having a user (actor) who acts as access to manage the information system that will be used, the user (actor) consists of Employees, Section Heads (KASI) and Heads of Offices. Employees can fill in the attendance list every working day. Section Head can process employee data, work target data, integrity and quality data as well as work performance data. The Head of Service can process user data and access employee performance reports.

Abstract

Cancer is something big in the world. Cancer is a malignant disease that is difficult to cure if the spread is too wide. However, detecting cancer cells as early as possible can reduce the risk of death. This study aims to predict the level of early detection of disasters in European countries using 5 classification algorithms, namely: Desecion Tree, Naïve Bayes, k-Nearset Neighbor, Random Forest and Neural Network of which algorithm is the best for this study. Tests carried out with several stages of research include: dataset (data contains), initial data processing, proposed method, credit method using 10 times cross validation, test results and t-test different tests. The alpha value is 0.05. if the probability is> 0.05 then H0 is accepted. If the probability is <0.05 then Ho is rejected. The results of the research that obtained performance with an accuracy value of 98.35% were the Neural Network algorithm. Whereas, the results of the research using the algirtic t-test with the best models are: Random Forest algorithm and Neural Network, the relatively good Naïve Bayes algorithm, the Desecion Tree algorithm is quite good and the poor algorithm is the K-Nearset Neighbor (K-NN) algorithm.

Abstract

Triple DES (Triple Data Encryption Standard) is one of the symmetrical algorithms on cryptography that is used to secure data in the form of text messages by encoding text messages. The process carried out in encoding the data, namely the encryption process and the decryption process. The triple DES algorithm is an algorithm for the development of the DES (Data Encryption Standard) algorithm. The difference between DES and triple DES lies in the length of the key used. In DES it uses one key that is 56-bit long, while triple DES uses three keys that are 168-bits in length (each of which is 56 bits long). In triple DES, the three keys used can be mutually independent (K1, K2 and K3) or only two keys are mutually independent and one other key is the same as the first key (K1, K2 and K3 = K1). Because the level of confidentiality of the DES algorithm lies in the length of the key used, the use of the triple DES algorithm is considered safer than the DES algorithm. To facilitate the use of the triple DES algorithm, a triple DES algorithm program was created with computer software tools, namely Microsoft Visual Studio 2008 which can encrypt and decrypt text messages.

Abstract

Learning is the process of interaction of students with educators and learning resources in a learning environment. Learning is assistance provided by educators so that an agreed process of knowledge and knowledge can occur, mastery of proficiency and character, and formation of attitudes and beliefs in students. In other words, learning is a process to help students learn well. Cryptography is a study of mathematical techniques related to aspects of information security, such as confidentiality data, validity data, integrity data, and authentication data. All information about information security can be regulated by cryptography. Cryptography can be interpreted as a science or senior for securing messages. Computer Assisted Instruction (CAI) is a system for delivering microprocessor-based subject matter that is designed and programmed into the system. Computer Assisted Instruction (CAI) defines as the use of computers in completing agreed materials with students actively and allows feedback

Abstract

Quick progress also occurs in the field of cellular communication networks with the concept of open systems, making it easier for someone to enter into the network. This can cause the process of sending data to be unsafe because it can be used by other parties who are not responsible for taking data and information in the middle of the road. To achieve the goal of maintaining confidentiality, various kinds of security techniques have been developed. To protect and maintain the confidentiality of data to avoid people who are not entitled to obtain this information, namely using cryptographic methods. In terms of data security techniques, many cryptographic methods can be used. Cryptographic methods have their own techniques and methods. One of the cryptographic methods that can be used is the Reverse Cipher method. But if you only use the Reverse Cipher method, text data security is very weak. So to achieve a higher level of security this method is combined with the RSA method which uses a public key and has high security because the difficulty of factoring large numbers becomes prime factors in the RSA algorithm.

Abstract

The development of technology makes the birth of a tool that is the forerunner to the formation of Short Messaging Service (SMS), namely pagers. However, with the community's need to send messages quickly, accurately and safely make technology experts create a device that is a cellphone. Cellphone or mobile was first created already equipped with SMS feature. When a message or data becomes important and is privacy, it is necessary to protect the data. Therefore experts created an algorithm method to secure data. This method is called the encryption and decryption method to secure highly confidential messages or information from irresponsible and unauthorized people. There are various kinds of encryption algorithms with each characteristic that can be used, one of which is the DES (Data Enryption Standard) algorithm. DES is a symmetric encryption algorithm, where the process of encrypting and decrypting messages uses the same key. So even though a cryptografe understands the algorithm used to encode the message, but if you don't know the key used, it won't be able to decrypt the message so that the SMS message is really safe.
