Abstract

Abstrak Kriptografi adalah ilmu yang mempelajari teknik-teknik matematika yang berhubungan dengan aspek keamanan informasi seperti kerahasiaan, integritas data, serta otentikasi. Algoritma RSA dan Triple DES adalah dua metode yang digunakan untuk proses enkripsidan dekripsi pada tugas akhir ini. Proses enkripsi dan dekripsi dengan ke dua algoritma tersebut digunakan pada enkripsi dan dekripsi file teks. Pada dasarnya ke dua algoritma ini berbeda berdasarkan kesamaan kuncinya. Pada algoritma RSA, menggunakan kunci yang berbeda untuk proses enkripsi dan dekripsinya. Sedangkan Triple DES setiap proses enkripsi maupun dekripsi data secara keseluruhan digunakan kunci yang sama. Pada tugas akhir ini dibuat perangkat lunak yang menggunakan bahasa pemrograman Visual Basic 6.0 untuk membandingkan ke dua algoritma tersebut. Perbandingan dilakukan dalam hal lama proses dekripsi antara algoritma RSA dan Triple DES. Kunci : Kriptografi, Algoritma RSA, Triple DES

Abstract

Examination is a process carried out to measure the achievement of student competencies on an ongoing basis in the learning process, to monitor progress, make learning improvements, and determine student learning success. In 2019, SMK Negeri 6 Bekasi City began to use the E-Exam Application for the implementation of exams, both the Mid-Semester Examination or better known as UTS, Semester Final Examination or better known as UAS and School Examination or better known as US. Approaching 2 years of use, the E-Exam Application of SMK Negeri 6 Bekasi City has not been analyzed for software. The results of the evaluation of the quality of the E-Exam software at SMK Negeri 6 Bekasi City are expected to be a reference for developing and fulfilling the wishes of every citizen of SMK Negeri 6 Bekasi City, to be able to carry out online exams well. ISO 25010 testing is a standard that is widely used to evaluate, measure and test the quality of software. The ISO used for this research is version 25010, this version is a continuation of ISO/IEC 9126 with the addition of several structures and parts of the quality model standard. In this study, we will discuss the analysis of application quality using the ISO 25010 standard.

Abstract

This research aims to analyze how the influence of digital comment factors affects the level of product sales on Shopee e-commerce. We use a quantitative-qualitative approach, utilizing primary data from digital product sales, opinions, and consumer assessments in e-commerce, along with secondary data from sources like product-related literature. The study population includes all products available through e-commerce. The sampling technique uses a combination of probability sampling and non-probability sampling. The research results show that the digital comment variable has a significant influence on the level of product sales in e-commerce. Research demonstrates that positive opinions significantly boost product sales, aligning with the widely held belief that positive feedback can bolster consumer interest and confidence in the product. On the other hand, negative opinions also show a significant positive influence, indicating that transparency and honesty in consumer reviews can have a beneficial impact on product sales. This highlights the importance of not only focusing on positive feedback but also managing negative reviews well as part of an effective marketing strategy in digital environments such as e-commerce. Digital consumer assessments do not show a significant influence on product sales. This suggests that consumers tend to trust first-hand experiences from other consumers' reviews rather than relying solely on numerical ratings in isolation.

Abstract

The rapid growth of urbanization in Palembang, South Sumatra Province, poses challenges in the management of energy resources and the environment. This study aims to evaluate the application of Internet of Things (IoT) in the E-Cleanness City Information and Management System program as a solution in improving energy efficiency and smart city operations. Mixed research methods were used, combining quantitative and qualitative analysis to obtain a comprehensive picture of the impact of IoT implementation. The results showed a 10% decrease in energy consumption and a 15% increase in operational efficiency after IoT implementation. The main factors contributing to the efficiency improvement include optimization of waste collection routes, reduction in the number of operational vehicles, and improved response times. In addition, user and system manager satisfaction surveys indicated high levels of satisfaction, indicating positive acceptance of the technology. The social and economic benefits include reduced operational costs, improved quality of life, creation of new jobs, and increased environmental awareness. However, challenges such as limited technological infrastructure, the need for further training, complex system integration, and data security and privacy issues need to be addressed to optimize IoT implementation. This research recommends infrastructure development, intensive training programs, and implementation of strong data security protocols as strategic steps to support the sustainability of smart city management in Palembang. The findings are expected to serve as a reference for the development of similar policies in other cities in Indonesia in an effort to achieve energy efficiency and environmental sustainability through IoT technology.
