Abstract

The problem formulation in this research are a) what is the level of students' ability in mastering the concept of Survey and mapping ?, and b) what difficulties do students experience in mastering the concept of Survey and Mapping?. The research approach uses both quantitative and qualitative approaches. The research procedure goes through several stages, namely a) preparation stage, b) problem formulation stage, c) data collection stage, d) data analysis stage, and e) research results. The population in this study is students of the Industrial Engineering Study Program of South Aceh Polytechnic, while samples are students of semester II of the Academic Year 2020/2021 Industrial Engineering Study Program as many as 1 (one) class. Research is conducted at South Aceh Polytechnic. The instruments in this research are test questions and interview guidelines. Data collection techniques in this study used tests and interviews. Hypothesis testing of students' ability level in understanding survey and mapping subjects (tests) using right-hand t-test at a significance level of 0.05 with acceptance criteria H0 if t t(1-α) and H0 declined for t other values. Interview data were analyzed with the following stages 1) reducing the data, 2) presenting the data, and 3) concluding the data. External must be in the form of an accredited national journal ranked 1- 6 which is published in the Journal of Innovation and Engineering Technology with the information accepted/published. Technology Readiness Level (TKT) is 3. The results of data analysis performed at a significant level α = 0,05 gained and = 1,73, so or 2,51 > 1,73. Thus, it can be concluded that students of the Industrial Engineering Study Program of South Aceh Polytechnic are able to master the concept of survey and mapping courses

Abstract

Making this application aims to create an application that can accommodate historical stories in South Aceh in the form of a reading application that is easily accessible. The making of this application is made with a programming language that is processed into an application that contains historical stories obtained from various sources as well as from narrators or historical storybooks in South Aceh. From the development of this application, a lot of knowledge was gained from historical stories in South Aceh. Making this application produces an application that includes useful and historical stories so that all historical stories in South Aceh are not lost and forgotten and can also be accessed easily by anyone.

Abstract

Information security related to computer use cannot be separated from cryptography. Hill cipher is an application of modulo arithmetic in cryptography. This cryptography technique uses a square matrix as the key used to carry out encryption and decryption. This cryptographic technique was created with the intention of being able to create ciphers (codes) that cannot be broken using frequency analysis techniques. Hill Cipher does not replace each of the same letters in the plaintext with other letters that are the same in the ciphertext because it uses matrix multiplication as a basis for encryption and decryption. Hill Cipher cryptography is a type of classic cryptography that uses a substitution method by providing random keys and the number is the same as the plaintext. The use of encryption and decryption using the Hill cipher algorithm is to help secure data so that it is not easily falsified or accessed by irresponsible people by changing the original image into a different form where the image is not easy to recognize. The encryption and decryption process was designed using the Java programming language using NetBeans 8.2 and the Hill Cipher algorithm to encrypt RGB digital images
