Abstract

Clickstream analysis is the process of collecting, analyzing, and reporting data of visited pages by visitor at the time of mouse clicks. Clickstream data are generally stored on a web server in the access.log file including IP Address data, reference pages, and access time. This study aims to analyze clickstream data by converting into the form of a comma sparated value (csv) so that the string inside of it could be grouped and stored in a database. The important information in the database was processed and retrieved by using one of the techniques in web mining called apriori algorithm analysis. Apriori algorithm implementation was done at the time of reading the database and table query analysis on the software developed. Results of this study were the statistics describing the level of access to web pages that were very helpful for web developers to develop web sites.

Abstract

Saat ini teknik kriptografi Hill Cipher telah diimplementasikan untuk beberapa aplikasi. Dalam implementasinya ada saja kesalahan atau kecerobohan seperti kunci matriks yang digunakan pada proses enkripsi hilang karena tidak disimpan atau bahkan lupa. Oleh sebab itu diperlukan teknik kriptanalisis untuk mendapatkan kembali kunci yang hilang tersebut. Teknik kriptanalisis pada kriptografi Hill Cipher yang telah diketahui adalah dengan menggunakan persamaan linier dan menggunakan perkalian matriks. Pada persamaan linier, nilai dari masing-masing variabel matriks kunci dapat diketahui, namun proses pencarian nilai pada tiap variabel tersebut tidak dapat dilakukan dalam waktu yang singkat. Sedangkan pada perkalian matriks, proses pencarian variabel matriks kunci hanya dapat dilakukan jika matriks yang merepresentasikan plaintext memiliki invers atau nilai determinannya sama dengan satu. Nilai determinan yang didapatkan dari suatu matriks dapat dioperasikan untuk mencari nilai suatu variabel dari operasi aljabar linear yang telah direpresentasikan kedalam bentuk matriks. Masing-masing variabel tersebut dapat melakukan proses pencarian determinan secara bersamaan. Dalam penelitian ini penulis akan mengembangkan suatu sistem untuk mencari nilai pada variabel matriks kunci berdasarkan perhitungan determinan matriks yang dikembangkan menggunakan paradigma System Development Life Cycle (SDLC) Waterfall dan diimplementasikan pada sistem operasi berbasis Android.

Abstract

Cattle are the livestock of the Bovinae family and subfamily Bovidae. They have been raised for beef and dairy products. Nowadays, beef production does not meet national needs. This is influenced by several factors. One of them is the farming pattern. However, knowledge about cattle farming is still scattered and unstructured. Knowledge Management System (KMS) offers a knowledge system that can be used to create, collect, store, maintain and disseminate knowledge. In this study, KMS for cattle farming has been implemented using the Knowledge Management System Life Cycle (KMSLC) method. The research results are web-based applications regarding cattle farming management that have been tested by experts and users, with the average test results declared good. The features possessed by this KMS application are knowledge capture, knowledge sharing, and knowledge application systems so that they can share knowledge between one user and another. In addition, this application is equipped with a discussion forum that can serve as a place to interact with fellow users or with experts.

Abstract

Geographic information system is a geospatial information system development of diverse data sources and heterogeneous includes news, events, routes and tourist attractions. The system provides information about the geographic location with integrated global positioning system (GPS). GPS is a system to determine the location on the earth's surface with the aid of the alignment of the satellite signal. GPS coordinates deci-sive point will be more complete if coupled with the use dijkstra algorithm to determine the shortest path to get to the tourist sites. Many tourist sites and have a short distance away from tourist spots and the other one is a problem because these sights are not known by the tourists who recently visited. In a case like this is necessary to travel guides which can provide information about the location - nearby tourist sites and pathways that can be bypassed by tourists. A cross between GPS and dijktra algorithms can be developed into a geographic information system based on Android that is interesting and informative in the field of tourism as a guide for tourists.

Abstract

AbstrakKriptografi merupakan suatu teknik  menyembunyian pesan dimana pesan tersebut hanya dapat diketahui oleh orang tertentu dimana pesan itu sering disebut dengan enkripsi.saat ini enkripsi sudah banyak dikembangkan salah satunya adalah metode Rivest Shamir Adleman (RSA) yang menggunakan dua kunci yaitu kunci publik dan kunci pribadi, dimana kunci tersebut dapat diatur dimana semakin panjang bit pembentukan kunci maka semakin sukar untuk dipecahkan karena sulitnya memfaktorkan dua bilangan yang sangat besar dan itu dianggap aman meskipun tidak pernah dibuktikan aman  tidaknya, maka dari itu dalam penelitian ini akan dibuat keamanan yang lebih baik lagi dengan memadukannya dengan metode playfair chiper dimana pada kunci publik yang diatur diubah terlebih dahulu atau di enkripsi dengan playfair chiper baru bisa dipecahkan kembali dengan algoritma Rivest Shamir Adleman (RSA).
