Abstract

This study aims to examine the influence of Simplified Data Encryption System (SDES) simulation on student learning outcomes in Cryptography lessons. The research employed a quasi-experiment. Data analysis to test the SDES simulation model was performed using ANOVA 2x2. The U-Mann Whitney Test was chosen to examine differences in student learning outcomes of treatment groups and control groups, while the effectiveness of the media is determined by differences in student learning outcomes between the pre-test and post-test results in the two groups. The test results show that: (1) There is a difference between the treatment group and control group, indicated by the U-Mann Whitney Test result (Ucount = 15 Utable = 23; α = 0.05), which means there is a difference of student learning outcome between students given learning by DES simulation media and those by PowerPoints Media. (2) There is a difference in the cryptography learning outcomes for the students with the high initial ability between the treatment group and the control group. The test result is Ucount = 0.5 Utable = 2; at α = 0.05. (3) There is no difference in student learning outcomes for low initial ability student groups using the DES simulation media, with high ability students group using PowerPoints Media; the statistical test results show Ucount = 11 Utable = 2; at α = 0.05. This study concludes that using U-Mann Whitney, it can prove that the SDES simulation model developed is effective for improving student learning outcomes in Cryptography lessons.

Abstract

The field of metrology is mainly legal metrology; seals are closely related to the guarantee or validity of a measuring instrument. Seals are designed so that it is not easy for other parties to open the seal. Seal damage must be identified as soon as possible. The application of the Internet of Things (IoT) is needed in the process of sending data in real-time. IoT technology can be applied to electronic seals to know and record the condition of the measuring device. Broken seals caused by irresponsible parties can cause losses to consumers and owners of measuring instruments. Electronic seals are expected to be able to detect seal damage caused by abuse of authority or fraud. The broken seal will send data to the server as well as SMS (Short Message Service) to the related party. Electronic seals can send damage data via SMS within 20 seconds with a success rate of 92% and sending data through the ThingSpeak web server within 40 seconds with a success rate of 82%.

Abstract

The main objective in this thesis is to facilitate people who often lose keys and also to monitor the door without the commute. Methods for designing experimental tools, starting with the concept of the system being designed, so that it can be seen how the instruments work tools and tool design has been tailored to the needs. In this system, the central lock is used to lock the door and controlled using a relay that is connected to the microcontroller ATmega 16. Making Home Door Lock Control System, using Bluetooth Connection Technology Based Android , has been through some process that has been carried out, including the manufacture of electronic circuits and manufacture of mechanical parts in the appliance. From the experimental results, it can be concluded that the tool has been working in accordance with the expected job description Tujuan utama dalam tugas akhir ini adalah untuk memfasilitasi orang-orang yang sering kehilangan kunci dan juga untuk memantau keadaan pintu tanpa harus bolak-balik. Metode dalam merancang alat percobaan ini yang dimulai dengan konsep sistem yang akan dibuat, maka mengetahui bagaimana kerja instrumen alat dan alat desain yang telah disesuaikan dengan kebutuhan. Pembuatan Sistem Pengendali Kunci Pintu Rumah Menggunakan Koneksi Bluetooth Berbasis Teknologi Android telah melalui beberapa proses yang telah dilakukan, termasuk pembuatan sirkuit elektronik dan pembuatan bagian-bagian mekanik pada alat. Dari hasil percobaan dapat disimpulkan bahwa alat ini telah bekerja sesuai dengan job description yang diharapkan.
