KRS-Online system is a web-based information system to assist the process of preparing the KRS of every student in University of Muhammadiyah Malang. In this research, the level of usability of the system will be measured and the relationship between the independent variables (usefulness, ease of use, and ease of learning) and dependent variable (satisfaction), either simultaneously or partially, will be analyzed. Usability measurement adopted in this study is USE questionnaire that contains usefulness, ease of use, ease of learning, and satisfaction variables. This research involves 100 respondents from the KRS-Online system users. The result shows that measuring usability produces feasibility of 73.312%, which means usability of KRS-Online system is "acceptable". On the other hand, this study proves that there is a significant influence between usefulness, ease of use, and ease of learning variables with the satisfaction variable simultaneously. In addition, usefulness and ease of use variables significantly affect the satisfaction variable partially, while the ease of learning variable does not significantly affect the satisfaction variable. Intisari-Sistem KRS-Online merupakan sebuah sistem informasi berbasis web yang berguna untuk membantu proses penyusunan KRS setiap mahasiswa Universitas Muhammadiyah Malang. Dalam makalah ini akan diukur tingkat usability system dan dinalisis hubungan antara variabel bebas, yaitu usefulness (kebergunaan), ease of use (kemudahan penggunaan), dan ease of learning (kemudahan mempelajari) terhadap variabel terikat, yaitu satisfaction (kepuasan) secara simultan maupun parsial. Pengukuran usability dalam makalah ini mengadopsi kuesioner USE yang memuat variabel usefulness, ease of use, ease of learning, dan satisfaction. Pengambilan data melibatkan 100 responden dari pengguna sistem KRS-Online. Hasil analisis menunjukkan bahwa pengukuran usability menghasilkan nilai persentase kelayakan sebesar 73,312 yang berarti usability sistem KRS-Online memiliki nilai "layak". Di sisi lain, dibuktikan bahwa terdapat pengaruh yang signifikan antara variabel usefulness, ease of use, dan ease of learning terhadap variabel satisfaction secara simultan. Selain itu, secara parsial variabel usefulness dan ease of use berpengaruh secara signifikan terhadap variabel satisfaction, sedangkan variabel ease of learning tidak berpengaruh secara signifikan terhadap variabel satisfaction.

Software development projects require experience and knowledge of the developer or clients related to the system which will be developed. Unclear clients' needs potentially emerge many changes of needs during the process of development which can not be resolved by using conventional software development methodology. The implementation of the less significant requirements either from the clients or the other stakeholders causes the project development becomes longer. Therefore, a technique is needed to arrange the priority of software requirements. In this paper, we combine personal extreme programming (PXP) methodology with Moscow technique to overcome those problems. PXP is suitable to use in small to medium-sized projects if the clients do not know in detail about the needs in the development of applications, applications needed in relatively quick time, and the development phase is adjusted to use by a single programmer. Moscow technique was used for prioritizing requirements elicited in PXP methodology. Moscow is a method to determine priority needs based on cost, risk, and business value. This technique was applied during the planning phase of PXP to develop library application, thereby it reduced the time of project completion. The result was a library application suited the needs of clients to support business processes at Batu State Attorney's library.

AbstrakKasus bencana alam atau kecelakaan yang sering terjadi di Indonesia menimbulkan banyaknya nyawa korban yang melayang, hal ini dikarenakan keterlambatan dalam hal pertolongan utama, selain itu banyak dari masyarakat yang tidak tahu informasi mengenai instansi atau nomor telepon darurat yang harus dihubungi ketika dalam keadaan darurat. Kecanggihan teknologi yang semakin berkembang pesat mampu memberikan inovasi terbaru sehingga menciptakan telepon pintar (Smartphone). Salah satu bentuk pemanfaatan teknologi yang ada adalah dengan cara menciptakan sebuah aplikasi darurat untuk menangani berbagai macam kasus seperti bencana alam, kriminal, kecelakaan, dan kebakaran. Tujuan dari penelitian ini adalah menghasilkan rancangan sistem aplikasi darurat dengan metode User Centered Design (UCD) untuk menganalisa kebutuhan sistem dan desain terdiri dari fitur, tata letak, huruf, ukuran huruf, dan warna, lalu menggunakan metode Waterfall untuk implementasi sistemnya. Penelitian ini menghasilkan sebuah aplikasi darurat yang sesuai dengan kebutuhan pengguna terdiri dari fitur kondisi, panggil, berita, petunjuk arah, share facebook, login, daftar, dan edit profile, lalu untuk desain sistem pengguna memilih huruf Times New Roman, ukuran huruf sedang, serta warna biru tua, biru muda, dan putih.Abstract Due to the delay of giving the first aid, the case of natural disasters and accidents that frequently happened in Indonesia cause the rise of fatalities. Besides, there are a lot of people who lack information about where and who to contact when they are in an emergency situation. Indeed, nowadays, technology is rapidly growing that it is able to provide innovations. The latest innovation that is created is the smartphone. Creating an application−that helps to handle various cases such as natural disaster, crime, accident, as well as fire−in a smartphone is one of the existing uses of technology.  As for the main purpose of this research is to generate the design of the emergency application system with User-Centered Design (USD) method to analyze system needs. The design itself consists of the feature, layout, font, size of the font, and color. In addition, for system implementation, Waterfall method is used. As a final product, this research produces a useful emergency application that suits the users’ needs. The application comes with many features: conditions, calls, news, directions, share to Facebook, log in, sign up, and edit profile. On the system design, the users can choose Times New Roman font, medium font size, and colors in dark blue, light blue, and white.

<p class="Abstrak">Kualitas merupakan faktor utama kesuksesan sebuah website. Salah satu karakteristik kualitas perangkat lunak menurut ISO 9126 adalah usabilitas. Pengukuran usabilitas sebuah website adalah hal yang penting mengingat sangat besarnya jumlah website saat ini. Salah satu metode yang dapat digunakan untuk mengevaluasi usabilitas website adalah <em>framework</em> Sirius. Sirius dapat menghasilkan nilai usabilitas global dan daftar elemen antarmuka sistem yang perlu diperbaiki. Namun, elemen-elemen ini belum diatur berdasarkan prioritas pengembang sistem dan hanya mempertimbangkan nilai peningkatan yaitu prosentasi perbaikan nilai usabilitas global jika elemen tersebut diperbaiki. Untuk itu dibutuhkan sebuah teknik untuk memprioritaskan elemen-elemen tersebut berdasarkan sudut pandang pengembang sistem sehingga sesuai dengan sumber daya yang dimiliki oleh pihak pengembang. Salah satu teknik yang dapat digunakan adalah Moscow. Moscow dapat mengelompokkan seluruh kebutuhan ke dalam 4 (empat) kelas berdasarkan tingkat prioritasnya. Penelitian ini melakukan modifikasi terhadap <em>framework</em> Sirius dengan menambahkan tahap perangkingan menggunakan teknik Moscow.  Berdasarkan hasil pengujian, penambahan tahap pengaturan prioritas dengan Teknik Moscow memberikan urutan kriteria usability yang lebih baik dalam hal nilai bisnis, resiko, dan biaya pembangunan website. Setiap tim pengembang website yang dianalisis memberikan hasil pengaturan prioritas Moscow yang berbeda-beda. Bagi tim website Lective, kriteria <em>usability</em> paling penting adalah berkaitan dengan aspek <em>labelling</em>, sedangkan bagi pengembang website Seminar Indonesia, aspek paling penting adalah kelompok <em>comprehensibility and ease of interaction</em>. Adapun pengembang website Simkesmas lebih menekankan pada aspek <em>control and feedback.</em></p><p class="Abstrak"> </p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Abstract"><em>Quality became the key element for website deployment. Based on the ISO 9126, one of the quality characteristics in software engineering is usability. The usability measurement on a website is an essential topic nowadays along with the incremental growth of it. One of the evaluation methods that can be used for analysing website usability is Sirius Framework. This method can produce global usability values and the list of a user interface element that should be modified. However, those elements have not been adjusted based on developer priority system which only considers the increased value of each element - the percentage of modified global usability value. Therefore, A technique called MoSCoW was introduced for prioritizing those elements from a developer point of views which corresponds to its available resource. MoSCoW can categorize all of the requirements into 4 distinct classes based on priority. This paper was performed for extending the Sirius Framework for implementing the ranking system by using MoSCoW. The experiment results showed that the MoSCoW method for priority adjustment process could produce better usability criteria on business, risk, and cost value during website development.</em></p><p class="Abstrak"><em><strong><br /></strong></em></p>
