The Importance Of End-User Analysis In New Information System Adapters: Lessons Learned From Practice

The implementation of Information System (IS) in new-IS adapters can remain unused even when they developed properly. The previous research shows that the unsuccessful IS utilization problem primarily related to behavioral issues rather than technical issues. The behavioral issues should be addressed in the stakeholder analysis, an activity in the inception phase of requirement engineering. End-users of an IS are one of the focuses in stakeholder analysis. We studied the correlation of the end-user analysis in new-IS adapters with the successfulness of IS utilization. We conducted a qualitative studied on 20 IS development projects. The findings show strong correlation of the end-user behavior and the IS adoption. We suggest the end-user analysis is necessary for the IS development project in new-IS adapters. We concluded that it is recommended to formally get the end-user commitment before starting the IS development process.

Case Study on Testing of Web-Based Application: Del's Students Information System

Software Testing is an important process to assure the quality of software including web-based application. The aim of testing is to detect all failures to ensure that the software is built in accordance with its specifications. There are two methods of testing, such as the white box and the black box testing. White box testing is done with the approach to the program code, while black box testing is done without referring to the source code, but to the output of the resulting program. User interface testing is the type of testing that is usually conducted on a web-based application. In this research, functional and user interface testing were conducted into Del’s Student Information System. Testing techniques used in this research was a Simple Functional Acceptance Test (FAST). This technique was done by testing each function and checking each component of the user interface. Selenium IDE was used to execute test cases resulting in the implementation. From all steps carried out in this research, it can be concluded that the functional testing can be carried out in line with the testing of the user interface. A testing scenario for web-based application has been proposed and experimentally applied into an application under testing

Penerapan Ontology Web Language pada Domain Ulos Batak Toba

Indonesia adalah salah satu negara di dunia yang kaya akan keanekaragaman budaya. Keanekaragaman budaya ini diakibatkan banyaknya suku di Indonesia. Setiap suku memiliki kekhasan masing-masing termasuk kekhasan dalam kain tradisional. Salah satunya adalah ulos, kain tradisional suku Batak Toba. Ulos merupakan simbol sakral dalam adat istiadat suku Batak Toba. Ulos terdiri dari berbagai macam jenis, motif, warna, makna hingga fungsi. Namun sangat disayangkan bahwa informasi mengenai ulos belum terdokumentasi dengan baik. Informasi didapatkan secara turun temurun dari satu generasi ke generasi lain yang memungkinkan informasi tersebut hilang. Selain itu, beberapa sumber yang ada juga menyajikan informasi yang berbeda. Oleh karena itu, ontologi bisa menjadi salah satu solusi untuk membantu mengelola informasi yang sudah ada supaya lebih terorganisir. Ontologi membantu memformalkan semua vocabulary pada domain ulos. Vocabulary itu kemudian dalam ontologi disebut sebagai konsep. Konsep tersebut akan saling berkaitan satu sama lain sehingga dapat dilihat sebagai suatu bentuk kesatuan (linked data) yang membentuk pola yang terstruktur. Kondisi ini yang kemudian mendukung pencarian dengan hasil yang bernilai semantik karena pola data yang disediakan saling berkaitan satu sama lain. Ontologi tersebut dapat direprentasikan menggunakan Web Ontology Language (OWL) yang merupakan vocabulary extension dari Resource Descriptive Framework (RDF). Kemudian untuk proses retrieving data akan menggunakan SPARQL.   Abstract Indonesia is a very rich country in cultural diversity. Most of the ethnic groups have their own uniqueness including the peculiarities in traditional textiles. One of them is Ulos, traditional cloth of Batak Toba. Ulos is a sacred symbol in the Batak traditions. Ulos consists of various types, motifs, colors, meanings and functions. However, it is unfortunate that information of Ulos has not been well documented. This cultural heritage is well-transferred from generation to generation. The existing sources sometime provide different information. Therefore, ontology can be one solution to help manage existing information to be more well-organized. Ontology helps formalize all vocabularies on the Ulos domain. The vocabulary in the ontology is called as a concept. The concepts are related to each other so that it can be seen as a linked data that form a structured pattern. This feature supports information searching with semantic value. The ontology of Ulos Batak Toba has been developed by using Web Ontology Language (OWL), which is a vocabulary extension of the Resource Descriptive Framework (RDF). Then for the data retrieving process we use SPARQ

The Implementation of Caching Database to Reduce Query’s Response Time

Performance is an imperative aspect of a web-based application. Response time is one of the most important performance parameters. Most of web-based applications are driven by database system. Reducing response time of its database system will improve the performance of a web-based application. Caching is one of techniques that can be implemented to reduce response time. The implementation of caching can be conducted in the application or database side. Caching is a technique to keep the executed query and hence the query will not be executed when called in the later execution. The result of an executed query will be stored in the cache therefore when that query is called, the database will retrieve the stored result without re-executing query. This mechanism will reduce the time to re-execute queries. However, this technique may be not suitable for all queries. This research is intended to investigate the effect of the implementation of caching into performance of a database. A series of experiments have been conducted by applying query cache. The response time of the application of query cache is compared with the response time of database without query. The results show that the implementation of query cache reduces response time significantly. However, this technique is more suitable for large database with many frequently asked queries. The number of clients accessing the database is found to be influencing the performance of caching. The more clients access the database, the more improvement is provided by query cache

Evaluasi Usability Website di Tenun

Suatu aplikasi harus memiliki sisi usability yang baik agar dapat dengan nyaman digunakan oleh pengguna. Website DiTenun adalah salah satu aplikasi berbasis web yang dapat membuat motif tenun baru dan sebagai media komersial untuk membeli dan menjual produk tenun. Website DiTenun belum pernah dilakukan evaluasi usability sebelumnya. Oleh karena itu, pada penelitian ini dilakukan evaluasi dan pengidentifikasian masalah usability dengan metode Heuristic Evaluation (HE) dan Usability Testing terhadap website Di Tenun untuk meningkatkan aspek usabilitynya. Hasil penerapan metode tersebut akan dibuat ke dalam bentuk prototipe interaktif website DiTenun sesuai perbaikan masalah usability yang ditemukan. Heuristic Evaluation merupakan evaluasi usability dengan melakukan tinjauan atau inspeksi suatu produk dari sisi ahli atau evaluator. HE pada penelitian ini mengacu kepada sepuluh prinsip evaluasi heuristik yang dikemukakan oleh Jakob Nielsen. Sedangkan usability testing merupakan evaluasi usability dengan aktivitas pengujian yang berfokus kepada pengguna. Sehingga evaluasi usability yang dilakukan terhadap website DiTenun akan dilihat dari dua sisi yaitu sis ahli/evaluator dan sisi pengguna. Untuk menyingkirkan masalah yang mungkin mengganggu pengguna sebelum usability testing, maka pertama sekali dilakukan heuristic evaluation. Setelah itu dilakukan pembuatan prototipe awal sesuai hasil dan rekomendasi HE untuk kemudian dilakukan usability testing terhadap partisipan sebagai penggua. Temuan permasalahan usability melalui hasil usability testing selanjutnya dianalisis dan diterapkan perbaikannya pada prototipe akhir. Hasil jumlah temuan permasalahan usability pada heuristic evaluation menunjukkan lebih banyak temuan dari hasil permasalahan usability pada usability testing, di mana pada hasil HE terdapat total 52 temuan sedangkan pada hasil usability testing terdapat total 37 temuan. Dari hasil tersebut menunjukkan bahwa implementasi HE di awal dapat mengurangi permasalah usability yang muncul bagi pengalaman pengguna pada saat usability testing. Kedua metode tersebut juga saling melengkapi untuk mengidentifikasi permasalahan usability dari sisi ahli dan sisi pengguna dalam menerapkan perbaikan permasalahan usability pada prototipe akhir website Di Tenun
