Abstract

This article describe results of research about development of library employees by the head master of state high school in Kabupaten Lima Puluh Kota. Populationis 35 people and be population research. The research instrument uses a Likert Scale. The result showed that: 1) Development of Organization Spirit (Corps) hasa good category (4.06), 2) Development of Capability Technical Services hasan enoughcategory (3.48), 3) Development of Capabilities Reader Services hasagood category ( 3.64), 4) Development of Moral Work hasan enoughcategory (3.39),and 5) Development of Job Performance hasa good category (3.77). So, total results show development of library employees by the Head master of State senior high school inKabupaten Lima Puluh Kota has a good (3.67). Keyword :library, development, library employe

Abstract

It is intuitively clear that the security of RSA cryptosystem depends on the hardness of factoring a very large integer into its two prime factors. Numerous studies about integer factorization in the field of number theory have been carried out, and as a result, lots of exact factorization algorithms, such as Fermat’s factorization algorithm, quadratic sieve method, and Pollard’s rho algorithm have been found. The factorization problem is in the class of NP (non-deterministic polynomial time). Tabu search is a metaheuristic in the field of artificial intelligence which is often used to solve NP and NP-hard problems; the result of this method is expected to be close-to-optimal (suboptimal). This study aims to factorize the RSA modulus into its two prime factors using tabu search by conducting experiments in Python programming language and to compare its time performance with an exact factorization algorithm, i.e. Pollard’s algorithm. The primality test is done with Lehmann’s algorithm.

Abstract

Petukaran data yang terjadi secara offline maupunonline sangat rentan dengan ancaman pencurian data. KombinasiCaesar dan Affine Cipher diharapkan mampu untuk menanganiisu keamanan data. Caesar Cipher bekerja denganmemanfaatkan pergeseran atau dikenal dengan shift ciphersementara Affine Cipher bekerja dengan menggunakan kunci duabuah bilangan integer. Kombinasi dua buah algoritma ini mampumengamankan data dan mengembalikan kembali ke bentukaslinya (plainteks), sehingga tidak menyebabkan integritasdatanya hilang.Kata Kunci—plainteks, cipherteks, Caesar cipher, Affinecipher.
