Abstract

Smart Home is one of the tools that is developed for ease of automation of smart home management from the start of address, security, comfort, savings, through automation with Android. In designing a micro home security system controller using raspberry pi 3 and Android smartphones that can reduce the number of criminal acts of burglary door. This tool consists of an electro magnetic door lock called a solenoid door lock.This solenoid key is placed on the door of the house for security. The design of this home door security system utilizes Raspberyy pi b + as a control device from near and far by utilizing the wifi network and sms gateway to control opening and closing the home door lock that is controlled via an android mobile. Through web bootstrap that will display the results captured by the camera to provide a home situation every time someone enters.This house door security system that has been successfully built and tested with the working principle if there is someone who forces or breaks the house door in a closed condition, the system will activate a warning or alarm by sounding the buzzer¸ because there is an LDR sensor connected to one switch connected to the solenoid key that results, if the key is opened with a security system then the LDR sensor will turn off and there will be no alarm, but if it is forced to break the LDR sensor will activate and read the movement of the door so that the reaction occurs and the buzzer alarm will sound. This security system is a solution to increase the level of home security ¸ besides this sophisticated system is very easy to use and integrated with android smartphones

Abstract

Keamanan dokumen digital menjadi aspek penting dalam menjaga kerahasiaan informasi, khususnya pada dokumen berbasis PDF. Penelitian ini bertujuan untuk menganalisis dan membandingkan performa algoritma kriptografi AES, Blowfish dan metode hybrid yang merupakan gabungan antara AES dan Blowfish dalam mengamankan dokumen yang ada di lingkungan pengadilan agama. Pada penelitan ini, menggunakan 6 dokumen dengan kisaran ukuran 261 KB - 1,7 MB serta proses enkripsi dan dekripsi dilakukan sebanyak 5 kali iterasi untuk memperoleh hasil yang konsisten. Adapun parameter evaluasi yang digunakan meliputi waktu eksekusi enkripsi dan dekripsi, entropi dan avalanche effect. Hasil penelitian menunjukkan bahwa AES memiliki performa terbaik dalam segi kecepatan dengan rata-rata waktu enkripsi selama 0,078 ms dan dekripsi selama 0,052 ms, yang merupakan nilai terendah dibandingkan Blowfish dan hybrid yang rata-rata waktu enkripsinya mencapai 0,554 ms. Sedangkan dari segi keamanan ketiga pendekatan tersebut menghasilkan nilai entropi yang tinggi dan relatif sama. Namun, pada hasil avalanche effect, hybrid menghasilkan nilai tertinggi mencapai 0,153, lebih unggul dibandingkan AES dan Blowfish. Dengan demikian, AES lebih unggul dalam efisiensi waktu, sedangkan hybrid lebih unggul dalam aspek keamanan.

Abstract

Refractive errors are a major cause of visual impairment among medical students and require appropriate knowledge, attitudes, and practices for effective management. This study aims to compare the knowledge, attitudes, and practices of medical students from the 2022 and 2023 cohorts at the Faculty of Medicine, Hang Tuah University, Surabaya, regarding refractive error correction. This analytic observational study employed a cross-sectional design. A total of 140 active medical students from the 2022 and 2023 cohorts were recruited using quota sampling. Data were collected through a validated self-administered online questionnaire distributed via Google Forms. Comparative analysis was performed using the Mann–Whitney U test with a significance level of α < 0.05. The results demonstrated a statistically significant difference in knowledge levels between the two cohorts (p < 0.001), with students from the 2022 cohort exhibiting higher knowledge scores. However, no significant differences were observed in attitudes (p = 0.086) or practices (p = 0.891) between the two groups. Although the majority of students exhibited positive attitudes toward refractive error correction, preventive and corrective practices in both cohorts remained suboptimal.
