Abstract

High-performance academic information systems and high availability services are requirement in every university. One of many reasons is for anticipation damage and fail server disrupting server network performance. Failover computer cluster method is applied to two servers: primary server as main server and secondary server as backup server. Four stages will be carried out: First: Installation and support software configuration. Second: installation and failover cluster configuration. Third: installation and Distributed Replicated Block Devices (DRBD) configuration. Forth: server testing with siege and nettool.This research conducted by doing server test before and after high availability. As if the main server has a system failure, it will automatically backup the main server to backup server to minimize user accessed data failures. System uses Ubuntu 16.04 LTS operating system. Based on the test data, it is acquired two data: packet data and data response time (ms). Data packets acquired from this research are: 233.3 average data sent; 228.3 average data received; 2.3 average data lost; while 59.7 average response time (ms) is showed; 2.7 minimum average; 633.8 maximum average. Data sent is 120B per data.

Abstract

Hijaiyah letters are letters used in the writing of the Holy Qur'an. In learning hijaiyah letters, many children still have difficulties so alternative learning methods are needed to make children more interested in recognizing hijaiyah letters. Interactive hijaiyah learning using electronic media is also still rare. Of the several hijaiyah letter recognition applications which are available, it is also limited in the use of certain operating systems. This research uses the waterfall method. The technology used to build web-based games in this study is HTML5 because HTML5 has the advantage of the flexibility to run on various platforms through a browser. In addition, this application does not require an installation process like other applications, but simply by accessing the web page, the application can be used. The results of this study are Hijaiyah Match games that can be run on various operating systems through a browser. The test results show that this application can help children learn hijaiyah letters.

Abstract

The design of adding a single sign on feature to one-door login authentication is a system design that allows library users to do the authentication process once to access various library applications such as OPAC, circulation, and visits. This design aims to improve user convenience, efficiency, security, integration, and identity management in the context of application use at XYZ Library. In the design of adding single sign on feature to this one-stop login authentication, library users will start the login process by entering their authentication credentials into the authentication system. The authentication system will verify the credentials and provide a secure authentication token to the user. This token will be used to access library applications linked to the authentication system without the need to log in repeatedly. The main advantage of the design of adding single sign on feature to this one-stop login authentication is the convenience for users as they only need to authenticate once to access various library applications. This increases user efficiency and productivity, reduces the risk of leakage or misuse of user credentials, eases integration with existing library applications, and enables centralized identity management. In conclusion, the design of adding single sign on feature to the one-stop login authentication at XYZ Library provides significant benefits in terms of user convenience, efficiency, security, integration, and identity management. It enhances the library's user experience and facilitates access to available services and resources.Keywords: Authentication, Design, features, Single sign on

Abstract

The development of software must consider usability as one of its key success indicators. Relatively few studies discuss the factors influencing usability, including users' backgrounds. The purpose of this research was to investigate the impact of user background, specifically gender, class (year of college admission), and frequency of use on the rating of usability.  This research utilized a descriptive quantitative method with instruments: the usability matrix of the Computer System Usability Questionnaire (CSUQ), the System Usability Scale (SUS), the Usability Metric for User Experience (UMUX), and the Net Promoter Score (NPS). The research object was the Learning Management System (LMS) of two state universities in Yogyakarta. Two sets of questionnaire responses were obtained: 305 men and 442 women answered the first time, and 280 men and 584 women answered the second time. Our result shows that the mean value of usability level from CSUQ, SUS, UMUX, and NPS is mostly higher in female than male respondents, in junior to more senior students, and in respondents who use the system more frequently than those who use it less.  This trend was consistent, even though the sequence of questionnaire choice order was reversed between the first and second data collection at the two universities. This research hence concluded that, based on gender, women tend to offer a higher rating of usability than men; based on class, the younger generation tends to provide higher ratings of usability than the older generation, and users who use the system more frequently tend to give higher usability rating than those who less use it.

Abstract

Software defect prediction is a practical approach to improving the quality and efficiency of software testing processes. However, establishing robust and trustworthy models for software defect prediction is quite challenging due to the limitation of historical datasets that most developers are capable of collecting. The inherently imbalanced nature of most software defect datasets also posed another problem. Therefore, an insight into how to properly construct software defect prediction models on a small, yet imbalanced, dataset is required. The objective of this study is therefore to provide the required insight by way of investigating and comparing a number of resampling techniques, classification algorithms, and evaluation measurements (metrics) for building software defect prediction models on CM1 NASA PROMISE data as the representation of a small yet unbalanced dataset. This study is comparative descriptive research. It follows a positivist (quantitative) approach. Data were collected through observation towards experiments on four categories of resampling techniques (oversampling, under sampling, ensemble, and combine) combined with three categories of machine learning classification algorithms (traditional, ensemble, and neural network) to predict defective software modules on CM1 NASA PROMISE dataset. Training processes were carried out twice, each of which used the 5-fold cross-validation and the 70% training and 30% testing data splitting (holdout) method. Our result shows that the combined and oversampling techniques provide a positive effect on the performance of the models. In the context of classification models, ensemble-based algorithms, which extend the decision tree classification mechanism such as Random Forest and eXtreme Gradient Boosting, achieved sufficiently good performance for predicting defective software modules. Regarding the evaluation measurements, the combined and rank-based performance metrics yielded modest variance values, which is deemed suitable for evaluating the performance of the models in this context.
