Sebuah Website memiliki peran yang cukup penting dalam membantu menyebarkan informasi bagi suatu kelompok atau masyarakat luas. Website yang bermanfaat adalah yang mampu memberikan sesuatu apa yang dibutuhkan oleh pengguna, selain itu mampu memberikan kemanfaatan bagi berlangsungnya proses bisnis yang terjadi dalam organisasi itu sendiri. Semakin banyak yang mengakses website suatu organisasi maka semakin dikenal. Demikian juga dengan STMIK Widya Pratama Pekalongan yang ingin memberikan pelayanan terbaiknya kepada masyarakat secara umum khususnya bagi mahasiswa dan seluruh karyawan dalam memenuhi permintaan informasi yang up to date melalui websitenya. Yang menjadikan pertanyaan adalah apakah website yang dimiliki oleh STMIK Widya pratama itu sebuah produk layanan yang dapat digunakan oleh pengguna serta memenuhi tanggung jawabnya dalam menyajikan antarmuka yang mudah untuk digunakan? Oleh sebab itulah pentingnya pengukuran kualitas website dengan metode usability testing dengan ditambah atribut baru berupa Comfortability bertujuan untuk lebih memaksimalkan ketergunaan(usability) dari interface yang ada dalam website tersebut. Setelah dilakukan pengujian usability dan uji selisih mutlak dapat disimpulkan 74,4% memiliki hubungan yang kuat antara usability dengan variabel bebas dan 55,4% usability dipengaruhi secara simultan oleh atribut Learnability, Efficiency, Memorability, Errors, Satifaction dan Comfortability, ini menunjukkan bahwa dengan penambahan atribut Comfortability dapat menguatkan/memaksimalkan usability dari website STMIK Widya Pratama.

<em>The Articulating of H-Rotor is a development of the turbine from H-Darrieus which has a straight blade tilted with the aim of correcting poor self-starting due to the dominance of lift force. How likely is the influence of straight blade slope on turbine performance and it is important to be examined. The aim of this study was to find out the effect of the straight blade slope of the Articulating H-Rotor turbine to increase the self-starting ability. Hydrokinetic turbine experimental test method was carried out in a water channel (flume) using 3 NACA 0018 profile blades with varying inclination angles of 0^o (vertical blade), 30^o (inflated blade) and -30^o (cupped blade). The result indicated that the Articulating H-Rotor hydrokinetic turbine with a blade slope of 0^o had a larger RPM value and it was more dominant in working with lift force. The Articulating H-Rotor hydrokinetic turbine with a blade tilted of 30^o provides higher torque and increases drag, increasing self-starting for rotation. The shape of the turbine frontal area with a blade slope of 30^o was better able to respond the kinetic energy that raised from the flow velocity distribution profile of the water flow. The results of this study can contribute to the design of the tilted blade H-Darrieus turbine.</em>
