Abstract

Abstrak— Aplikasi pengelolaan laboratorium komputer dirancang dan diterapkan sebagai studi kasus pengukuran evaluasi tingkat kegunaan, dengan tujuan akhir sebagai peningkatan layanan dari laboratorium. Aplikasi dirancang untuk dapat mengakomodasi tiga tingkatan pengguna dengan memiliki empat fitur utama, yaitu: chatting, internet connection, service request serta information. Hasil rancangan dan implementasi aplikasi telah dievaluasi dengan menggunakan standar ISO 9241-11 untuk mengukur tingkat kegunaan (usability) terhadap pengguna, tiga faktor yang terlibat dalam pengukuran adalah efektivitas, efisiensi, serta kepuasan. Pengukuran tingkat kegunaan penting untuk menentukan tingkat penerimaan pengguna terhadap aplikasi dan sekaligus sebagai sarana pengumpulan masukan untuk penyempurnaan aplikasi bagi pengembang. Hasil evaluasi untuk tingkat efektivitas menunjukkan angka keberhasilan yang tinggi terhadap penggunaan aplikasi, yaitu 90-100%. Sedangkan hasil pengukuran efisiensi menunjukkan waktu penggunaan fitur yang masih belum merata, ada sebagian fitur yang masih belum intuitif sehingga membutuhkan waktu yang cukup panjang bagi pengguna untuk mengoperasikan sebuah fitur, dengan waktu terlama 20 detik. Sejalan dengan hasil evaluasi efektivitas yang tinggi, pengukuran tingkat kepuasan pengguna juga menghasilkan contribution score yang signifikan di angka 88,75, sehingga dapat ditarik simpulan bahwa pengguna hanya memiliki sedikit ketidaknyamanan pada aplikasi dan relatif memberikan penilaian positif pada implementasi aplikasi.Kata Kunci—Evaluasi usability, Perancangan Perangkat Lunak, Standar ISO 9241-11, User ExperienceAbstract— A laboratory management application has been designed and implemented as a case study for usability evaluation of the application, with the final aim is to increase the service level of the laboratory. The application is designed to accommodate three different users with their own specific roles and also has four main features, that are: chatting, internet connection, service request, and information. The result of the application’s design and implementation have been evaluated using ISO 9241-11 standard to measure the effectivity, efficiency, and satisfaction. The measurement of usability level is important for determining the users’ acceptance level of application and also as a feedback mechanism for the benefit of application improvement by the developer. Evaluation results for effectivity level show a high success rate of the application usage, as big as 90-100%. While the efficiency measurement results show the time of use of application’s features that are still not evenly distributed, there are several features that are not quite intuitive and require a long time for users to accomplish some particular tasks, with the longest time is 20 seconds. In line with the high result of effectivity, measurement of users satisfaction also show a significant contribution score at 88,75, so it can be concluded that users only have minor inconvenience against the application and tend to have a positive rating to the application.Keywords— ISO 9241-11 Standard, Software Design, Usability Evaluation, User Experience

Abstract

Cryptography is one of the security techniques that secure information confidentiality and information integrity while electronic transaction processing. There are three kinds of cryptograpy protocols, Symmetric Algorithms, Asymmetric (Public Key) Algorithms, and Cryptographic Protocols. Elliptic Curve Cryptography (ECC) is one of the public key encryption. ECC requires high computation for solving arithmetic operations.Finite field has important role in ECC implementation, which curve operations requires finite field. Finite field has several arithmetic operations, add, multiplication, squaring, and invers. There are many method or algorithm for each arithmetic operation. Finite field can be representation in prime field GF(p) and binary field GF(2m). There are two representation in binary field, polynomial basis and normal basis. This research presents implementation of arithmetic operation algorithms for adding, multiplication, squaring, and invers on polynomial basis with maximum key 299 bits. Besides that, this research presents the measurement of algorithm performance based on processing time and memory usage. Keywords — cryptography, elliptic curve, finite field, polynomial basis, binary field
