<![CDATA[Research is a process to solve problems. To solve existing problems, researchers must process data related to the problem to be solved. Data processing can be done using the SPSS application program, but the results obtained are still in the form of numerical values that must be concluded with sentences. To speed up data processing and determine conclusions, it is necessary to build an application for evaluating the influence of research variables and their impacts to help researchers, especially in the social field, to speed up in determining conclusions on evaluating the influence of research variables and their effects using the Pearson product moment method and simple linear regression. With the application that was built, the correlation coefficient of monthly money on student GPA is 0.0603 and the regression equation Y= 3.1319 + 0.0084 X , where there is an effect of student monthly money on student GPA of one hundred thousand rupiah, then the student's IP will increase by 0.0084]]>

<![CDATA[Manusia untuk bisa berkomunikasi dengan diri sendiri dan orang lain dituntut memiliki kemampuan membaca. Minat baca akan tumbuh bila didukung dengan bahan-bahan bacaan yang memadai dan diminati oleh pembacanya, sebab dari bahan bacaan itulah seseorang akan menjumpai berbagai hal yang belum pernah diketahui sebelumnya. Metode SMART merupakan metode dalam pengambilan keputusan multi atribut. Teknik pengambilan keputusan multi kriteria ini didasarkan pada teori bahwa setiap alternatif terdiri dari sejumlah kriteria yang memiliki nilai-nilai dan setiap kriteria memiliki bobot yang menggambarkan seberapa penting dibandingkan dengan kriteria lain. Pembobotan ini digunakan untuk menilai setiap alternatif agar diperoleh alternatif terbaik. Untuk itu penulis mencoba membuat suatu Sistem Pendukung Keputusan Menentukan Minat Baca siswa Dalam Peminjaman Buku. Dalam pembuatan Sistem Pendukung Keputusan ini penulis menggunakan MS. Visual Basic 2010 untuk mengolah data. Dengan demikian dapat dibedakan proses kerja yang manual menggunakan metode SMART. Dari hasil perhitungan dari 20 data yang telah dilakukan, diperoleh hasil perangkingan dengan nilai tertinggi yaitu Fahira Rambe (A7) dengan nilai 0,83 yang artiya memiliki minat baca tertinggi di antara murid lain.]]>

Multimedia Development Life Cycle (MDLC), adalah teknologi dengan konsep menggabungkan dimensi dunia nyata dengan dimensi dunia maya yang di tampilkan secara realtime. MDLC tidak seperti realitas maya yang yang sepenuhnya menggantikan apa yang ada di dunia nyata, namun hanya sekedar menambahkan atau melengkapi. Hal ini dilakukan dengan cara 'menggambar' objek tiga dimensi pada marker, yakni sebuah 'pola' yang bersifat unik dan dapat dikenali oleh aplikasinya. Smartphone memungkinkan pengembangan aplikasi Augmented Reality dengan murah serta dapat diakses oleh banyak pengguna. MDLC dapat dimanfaatkan dalam berbagai bidang salah satunya adalah sebagai sarana untuk pengembangan kebudayaan yang ada disetiap provinsi. MDLC dapat digunakan untuk menciptakan sebuah lingkungan pengenalan yang lebih interaktif dimana pengguna dapat berinteraksi langsung dengan obyek dunia maya sehingga pengguna pun dapat sambil belajar. Penulis mengembangkan sebuah aplikasi yang ditujukan kepada para seluruh pengguna aplikasi. Aplikasi ini akan berjalan pada platform mobile android untuk memudahkan pengguna untuk mengaksesnya.

<![CDATA[Masalah Keamanan merupakan salah satu aspek penting dari sistem informasi. Begitu pentingnya nilai informasi menyebabkan seringkali informasi diinginkan oleh orang tertentu kemudian dapat memodifikasi informasi tersebut. Untuk dapat mengesahkan informasi yang didapatkan, maka harus dilakukan authentication pada informasi sehingga diketahui keaslian informasi. Dalam penelitian ini diimplementasikan suatu metode secure hash algorithm, sehingga penerima informasi dapat mengetahui adanya perubahan terhadap data penting yang diterima dari pihak lain. Metode ini mampu membangkitkan nilai hash dari sebuah string atau file. Dengan perubahan sekecil apapun pada informasi yang diterima, dapat diketahui keasliannya. Secure Hash Algorithm adalah fungsi hash yang bekerja satu arah, ini berarti pesan yang sudah diubah menjadi message digest tidak dapat dikembalikan menjadi pesan semula. Dua pesan yang berbeda akan selalu menghasilkan nilai hash yang berbeda pula. Hasil rancangan perangkat lunak ini dengan input panjang string yang berbeda akan menghasilkan output dengan panjang string tetap yaitu 160 bit.]]>

<![CDATA[Tobacco is cultivated through a series of special processes, which is a very important crop in industry due to its significant impact on the economy. Making seeds, soil preparation, planting, care, up to the harvest phase, and post-harvest processing are all tasks included in this stage. These plants often show various signs of disease during their life cycle, which can seriously worsen if not treated quickly. In situations like these, effective solutions are needed to find and nip the problem in the bud. An expert system application has been developed in recent research to overcome this problem. This system relies on the backward chaining method, a clever technique for diagnosing diseases in tobacco plants. With this method, the application tries to search and find facts that match the current data to set the right diagnostic goals. This research not only allows users to better diagnose diseases in tobacco plants, but also helps develop prevention strategies so that similar diseases do not appear again in the future.]]>
