Abstract

Perkembangan teknologi perangkat bergerak mulai mengarah ke dimensi yang lebih kecil serta pembuatan aplikasi yang cepat, terkoneksi dan efisien. Dengan mengecilnya dimensi, efisiensi energi aplikasi perangkat bergerak menjadi sangat penting. Aplikasi ponsel berkembang sangat cepat, seluruhnya terhubung pada aplikasi seperti sosial media, hal ini menjadi kebutuhan sehari-hari. Baterai memasok kekuatan daya yang terbatas pada perangkat komunikasi bergerak, social media harus meminimalisir sinyal untuk mempertahankan konsumsi daya serendah mungkin. Rangkaian eksperimental dikembangkan dengan menggunakan mikrokontroller yang dapat mengukur konsumsi energy pada perangkat smartphone android pada jaringan 802.11. Hasil eksperimen menunjukkan bahwa whatsapp mengkonsumsi daya lebih kecil dari aplikasi lainnya pada proses standby dan chat, yang kedua aplikasi Instagram dan skype mengkonsumsi daya tinggi. Untuk proses keseluruhan youtube dan tik tok mengkonsumi paling tinggi.

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

Abstract

Adolescents are currently growing up in the digital era with the increase and development of internet technology which not only brings benefits, but also harms, one of which is exposure to sexual content, namely pornography. The increase of information and technology development constructs adolescents that are susceptible to the possibility of pornography exposure through accessibility such as social media and online games. Pornography is one of the negative impacts that can affect adolescent behavior, so it requires supervision. The role of parents is really needed by adolescents in providing sexual knowledge information and safe internet use, as well as support as an effort to prevent pornography exposure. This study aims to examine the relationship between family support and pornography exposure in adolescents. This descriptive correlative design used a cross sectional study. The population was all students in one of the State Junior high Schools in South Aceh Regency with a sample of 94 students. Data collection was carried out using questionnaires as a research instrument. Chi Square test was used in analyzing the data. The Results indicated that 66% of adolescents were exposed to pornography. The results of the analysis showed that there was a significant relationship of p=0.0001 (p<0.05) between family support and pornography exposure. Family support has a significant relationship with pornography exposure. It is expected that families and schools can increase support in monitoring and preventing adolescents from accessing pornography.
