Abstract

Seiring dengan perkembangan informasi yang terus meningkat salah satunya penggunaan komputerisasi dalam berbagai bidang. Hal ini erat kaitannya dengan penggunaan password dalam area komputerisasi. Rawannya manupulasi password dinilai sebagai hal yang perlu dicegah menggunakan data hiding. Salah satu teknik dalam data hiding yaitu Kriptografi. Dalam kriptografi terdapat banyak algoritma, salah satnya yang memiliki kehandalan yaitu algoritma blowfish. Sampai saat ini algoritma Blowfish belum ditemukan kelemahan yang berarti hanya adanya weak key dimana dua entri dari S-box mempunyai nilai yang sama. Belum ada cara untuk mengecek weak key sebelum melakukan key expansion, tetapi hal ini tidak berpengaruh terhadap hasil enkripsi. Hasil enkripsi dengan algoritma Blowfish sangat tidak mungkin dan tidak praktis untuk di terjemahkan tanpa bantuan kunci. Sampai kini belum ada Cryptanalysis yang dapat membongkar pesan tanpa kunci yang enkripsi oleh Blowfish. Hasil pengujian menunjukkan bahwa aplikasi bisa menjalankan fungsi-fungsi untuk melakukan proses enkripsi dan dekripsi data dengan baik. Waktu proses untuk enkripsi dan dekripsi untuk masing-masing file mempunyai sedikit perbedaan dikarenakan ukuran antara plainteks dan cipherteks juga berbeda, sedangkan waktu yang diperlukan juga lebih lama. Penelitian ini telah menghasilkan aplikasi enkripsi password yang telah diuji coba dan algoritma blowfish terbukti handal dalam mengamankan password.

Abstract

In this digital era, using learning applications is an alternative way to master programming. Conventional methods are considered less efficient, so a programming learning application is needed that can be adapted to user needs and provide a satisfactory user experience. Usability is an important factor in determining effectiveness and user comfort level. To meet success, a system or application must meet user expectations and produce a positive user experience. The data collected is primary data of a qualitative nature. To evaluate the system, the system usability scale method is used. The research results show that on average 23 respondents, the system usability scale score is 40 (worst imaginable). This score is still below the average, namely 68, so a redesign is needed to improve the user experience of the system.

Abstract

As we know, Bali is one of the world destinations and can develop its tourism well. Apart from being famous for its natural beauty nature, culture and friendly people, Bali also offers a variety of culinary delights for tourists that can be ordered at restaurants, tourist objects or at hotels there. Many recommendations for places or restaurants/eating places with various mainstay menus are needed to make it easier for tourists to find the food menus they want and meet their budget. In this research expected to be solved by combining the Methodology technique with a semantic ontology model. Designing an ontology model for restaurant/dining recommendations in Bali using the protégé application, the ontology model was developed into a structure for students with classes, attributes, and other elements arranged hierarchically. To get the right answers, the ontology assessment procedure using SPARQL queries is employed. Keywords: Restaurant in Bali, Ontologi, Methontology, SPARQL, Protégé

Abstract

In this study, the main objective was to calculate the range of physical values contained in mammography X-ray images and determine the physical quantities that are significant in differentiating between the histopathological types of ILC (Invasive Lobular Carcinoma) and IDC (Invasive Ductal Carcinoma). The research method involved collecting data from 152 mammograms consisting of 7 ILCs and 145 IDCs from doctor Sutomo Surabaya's radiology database. The range of physical values such as entropy, contrast, second angular moment, differential invest moment, mean, deviation, entropy of Hdiff, angular moment of Hdiff, and mean of Hdiff are calculated and compared between ILC and IDC using the Anova statistical test. The results showed that there were differences in the range of physical quantity values between ILC and IDC. Significant parameters in differentiating the two types of histopathology are mean1, mean2, mean3, and mean4. In conclusion, IDC has a higher peak than ILC, and the range of ILC physical quantities is higher than IDC. Keywords: X-ray, IDC, ILC, Mammografi, Anova

Abstract

This research applies the K-Nearest Neighbors (KNN) algorithm to classify medicine types based on patient symptoms using a dataset from Kaggle with 200 rows and 6 columns. After preprocessing steps such as handling missing values, encoding categorical variables, and splitting data into training and testing sets, exploratory data analysis (EDA) was performed to understand the dataset's structure. The KNN model was evaluated with k values of 1, 2, and 3, finding the optimal k to be 3, achieving an accuracy of 77.50% with average precision of 0.76, recall of 0.69, and f1-score of 0.66. Lower accuracy was observed for k=2 (65.00%) and k=1 (67.50%), indicating that k=3 is the most effective for this dataset. These results suggest that while KNN is a viable method for classifying medicine types based on symptoms, larger datasets are recommended for improved accuracy.

Abstract

Internet Service Provider (ISP) is a company that provides internet services. Technological developments and changes in human behavior require ISPs to develop their services effectively and efficiently to face competition. The internet network infrastructure that is currently being used is felt to be not adaptive enough in responding to solutions to technological changes appropriately. In this study, using the research object at Biznet and assisted by the TOGAF research method. The Open Group Architecture Framework (TOGAF) is an enterprise architecture framework that provides a comprehensive approach to the design, planning, implementation and governance of corporate information architectures. This architecture is usually modeled by four levels or domains, namely business, applications, data and technology. In this study, it proven that TOGAF is the right method in making a better internet network infrastructure development strategic plan. The research process has several phases, namely Preliminary Phase, Architecture Vision, Business Architecture, Information Systems Architectures, Technology Architecture, Opportunities and Solutions, Migration Planning, Implementation Governance, and Change Management. This research testing method is the result of a Forum Group Discussion (FGD) which produces a business process design, information system and network topology that can be used as a reference for the development of internet network infrastructure at Biznet
