Abstract

Pemasaran yang dilakukan oleh pengrajin handycraft di Desa Lopait Kecamatan Tuntang Kabupaten Semarang, menggunakan pemodelan pemasaran tradisional, yang hanya bergantung kepada tempat pengrajin memamerkan produk mereka. Keterbatasan pemasaran yang bergantung hanya kepada tempat produksi atau lokasi sekitar tempat produksi menyebabkan rendahnya tingkat penjualan.             Perkembangan Teknologi Informasi yang semakin pesat membuat pola pemasaran mengalami perubahan, pemanfaatan internet menjadi salah satu alternatif yang banyak dipakai perusahaan untuk memasarkan produknya. Dengan adanya situs online maka kesempatan pengembangan pemasarana akan semakin besar karena jumlah pengunjung tidak hanya berasal dari kota sekitar atau daerah sekitar akan tetapi seluruh pengguna internet. Informasi produk baru hingga perubahan harga dapat dilihat secara langsung dari situs pengrajin. Dengan adanya situs online diharapkan masyarakat dunia akan mengetahui adanya produk-produk dari desa Lopit. Sebagai alternatif memecahkan masalah akan dikembangkan model pemasaran secara online, yang tidak mengenal batasan dan waktu dalam pemasarannya. Model pengembangan sistem yang dipakai dalam membuat web ini adalah System Develop Life Cycle (SDLC)

Abstract

Grafika  Komputer atau  computer graphics  adalah  bagian  dari ilmu  komputer yang  berkaitan  dengan pembuatan  dan  manipulasi gambar  (visual)  secara  digital.  Bentuk sederhana  dari grafika  komputer adalah grafika  komputer 2D yang  kemudian  berkembang  menjadi grafika  komputer 3D.  Pola  penggambaran  yang paling sederhana adalah dengan menggunakan titik pada teknologi garis. Algoritma Line Equation merupakan salah satu metode untuk menentukan lokasi koordinat titik pada teknologi garis dalam grafika komputer dengan cara menentukan nilai gradien garis serta garis yang berpotongan dengan sumbu Y, sehingga bisa mengetahui pixel yang akan menyala pada screen coordinate

Abstract

Faculty of Information and  Communication Technology (FTIK) USM is one of the faculty are experiencing rapid development both of the number of students  and the amount of infrastructure. FTIK occupying the building M and Q as lectures and laboratory building for student. FTIK is growth oriented faculty of Information Technology, of the entire student FTIK and academic staff need internet access to support existing teaching and learning process. When the researchers were in building M and Q,  Our will compete for free internet access is provided USM because the bandwidth is allocated evenly to rent USM. The fact that there are today, when researchers were on the 2nd floor of building A, as home base for the Faculty of Agricultural Technology, researchers gain access  internet very easily. This is contrary to the conditions in the building M and Q, whereas the number of students in the Faculty of Agricultural Technology , not as much  as in FTIK.Based on the above problems, reserchers are interested to observe, analyze the access bandwidth at USM that occured during the period of active classes and the end of the course by means of internet access at USM monitoring using NDLC (Network Development Life Cycle) and will appear in the display MRTG.Objectives to be achieved by theresearcher is output obtained from a study that is able to provide inout to the wisdom of allocating bandwidth has been hired can be used optimally by the entire academic community USM.

Abstract

Pada lingkungan air bawah laut, faktor cahaya sangat mempengaruhi hasil kualitas citra yang didapatkan. Dengan semakin dalamnya pengambilan gambar bawah laut, maka hasil yang didapatkan nantinya akan semakin gelap kualitas citra bawah air laut tersebut. Dengan hasil kualitas citra air bawah laut yang buruk ini nantinya akan mempengaruhi hasil pencocokan pasangan gambar air bawah laut dengan metode algoritma SIFT. Dalam peneilitian ini, kami bertujuan untuk menggunakan metode baru preprocessing untuk meningkatakan kualitas citra bawah laut dengan menggunakan Koreksi Gamma. Hasil menunjukkan bahwa setelah menerapkan Koreksi Gamma pada algoritmas SIFT, keberhasilan dalam mendapatkan titik pencocokan pasangan gambar atau citra bawah laut meningkat 11,22% dibandingkan dengan keberhasilan algoritma SIFT tanpa peningkatan kualitas citra. Dari hasil uji t-test berpasangan menunjukkan bahwa hipotesa null ditolak dan menyimpulkan adanya perbedaan yang signifikan antara hasil SIFT tanpa peningkatan kualitas citra dengan SIFT yang menggunakan preprocessing Koreksi Gamma

Abstract

Dominant indicator of the use of multimedia in learning needs to be studied using the Confirmatory Factor Analysis. This study aims to determine the most dominant factor affecting the use of multimedia in learning, this study uses the Technology Acceptance Modelling theory. This study uses the technique of Judgment Sampling Area or a sampling technique that is based on the determination of the research area. Determination of the study area are four private universities in Semarang, namely USM, Udinus, STMIK Provisi and Unisbank, so the overall number of respondents as many as 200 students. This study shows that: 1-the greatest contribution value of the Perceived Usefulness latent variable that is multimedia learning increase the effectiveness of learning in the classroom, 2-the greatest contribution value of the Confirmation latent variable, that is Lecturer Services using multimedia learning is preferred, 3-the greatest contribution value of the Perceived Ease of Use latent variable that is teaching materials using multimedia learning is something that is easy for students to understand. This study also shows that : 4-the greatest contribution value of the Satisfaction latent variable that is multimedia learning used by Lecturer in teaching and learning in the classroom is able to provide information in accordance with the information that students need, and 5-the greatest contribution value of the Continued IT Usage Intention latent variable that is students interested in understanding the material, which is taught by Lecturer, if Lecturer teaching using multimedia based than conventional models
