Abstract

The goals of this research are to analyze factors affecting buying interest of e-commerce customers residing in the areas of Jakarta, Bogor, Depok, Tangerang, and Bekasi in Indonesia. A questionnaire is developed as the data acquisition instrument and is pretested by 30 respondents. The pretest is intended to evaluate the validity and reliability of the instrument. For the research, the data are collected from a random sample of 200 respondents. The research variables are ease of use, enjoyment, shopping experience, trust, promotion/advertising, and price. A structural equation model is established to assess the relations between the interested variables. As the results, the analysis shows that the factors of ease of use, promotion/advertising, and price significantly influence the buying interest. Meanwhile, the enjoyment, shopping experience, and trust do not affect the buying interest.

Abstract

IEEE 802.11ah is a new task group on the IEEE 802.11 standard designed to work on the 900 MHz. It is with a range of communication coverage up to 1kilometer, lower energy consumption, and up to 8191 stations. There are two types of STAs in 802.11ah: sensor type to support sensor service and non-sensor type for offload service. In this research, it only focuses on non-sensor STA. For non-sensor STA, maximizing throughput is more important than power consumption. This research aims to see the performance of IEEE 802.1 1ah with Enhanced Distributed Channel Access (EDCA). To achieve that purpose, a mechanism is needed to provide guarantees various services required by theSTA. EDCA is an access mechanism used to set the Quality of Service (QoS) for the IEEE 802.11 standard through modifications in MAC layer. In this research,it focuses on one of the EDCA parameters, Arbitration Inter-Frame Space (AIFS). In addition, this research also focuses on the 802.11ah feature is Restricted Access Window (RAW) by changing the number of the RAW groups. From the results of the research, it is found that the improvement scheme with Arbitration Inter-Frame Space Number (AIFSN) value AC BK = 2, AC BE = 1, AC VI = 1, AC VO = 1 has better performance compared to the default scheme with AIFSN value AC BK = 7, AC BE = 3, AC VI = 2, AC VO = 2) with an average throughput of 1.504598 Mbps, average overall delay of 0.066242 second and average PDR of 62%. In addition, changes in the number of RAW groups and RAW slots affect network performance. This feature can improve the value of throughput, average delay, and Packet Delivery Ratio. The goals of this research is to know the effect of AIFSN value changes on AIFSN parameters, variation of RAW group and RAW slot number to throughput,average delay and packet delivery ratio.

Abstract

Rapid growth in information technology forces various industries and business owners to think strategically to reach public attention. This condition also brings the logical consequence of using online medium as their primary marketing tools. Various online medium or usually called as social media such as Twitter, Path, and Facebook have been used by numerous industries as tools to communicate their ideas, brands, and promotion to the public. Along with this condition, industries need to think strategically to develop contemporary marketing communication strategy. This research is a case analysis focusing on examining marketing communication strategy of a brand. One brand identified is Pocari Sweat, Japanese isotonic drink brand. This brand is selected due to the availability of our computer devices to track the tweets. From this study, we have concluded that in this disruption era, marketing communication strategy can be known and identified by others only by tracking their digital footprint.

Abstract

This paper proposes the comparison of using K-Means and Fuzzy C-Means (FCM) to optimize the premise parameters on Adaptive Neuro-Fuzzy Inference System (ANFIS) for weather forecasting. The ANFIS architecture groups each of the feature inputs in the first layer into three clusters, and uses three rules for the second layer. The comparison is performed based on the RMSE value and the number of iteration. The testing is done on the percentage of 40%, 50%, and 60% of the total data. In addition, the testing is done by grouping the data based on season called rainy and dry seasons. The testing results show that both K-Means and FCM havealmost the same RMSE, except for rainy season where K-Means has better RMSE. However, K-Means requires relatively more iterations to achieve convergence. The use of FCM, in general, gives better results than K-Means. It is also shown that ANFIS provides the best performance for data onto the dry season.

Abstract

This study aims to develop a video game for toilet training materials as a medium for self-help learning for children with autism. Toileting skill is one of the basic self-help skills that children should master. In fact, teaching new things to children with autism is challenging. It requires a proper method to deliver the materials to these children. One of the effective learning media to teach self-help is to use visual media like video games. By using video games, children are expected to play and learn self-help skills, particularly about toileting. In addition, the video game is developed by applying certain design principles that fit with the needs of children with autism. The software is tested for its functionalities. Moreover, an implementation test is done by using observation communication analysis. Based on the results, the researchers conclude that the developed video game has implemented the proper design and materials related to toileting in accordance with the needs of children with autism. The respondents show positive results for using the video game.

Abstract

Although studies of the benefits of Enterprise Resource Planning (ERP) have been done before, the analysis of accountant satisfaction models in using ERP systems has not been explored specifically from the perceptions of accounting benefits, operational benefits, individual productivity, and managerial benefits. There has been significant growth in the use of ERP systems in Indonesia. Therefore, this study proposes a model of the accountant satisfaction in using the ERP systems. The population of this study is the accountants working in Jakarta. The data are collected from ERP users in several companies in Jakarta by using a questionnaire with snowball sampling method. As much as 282 respondents return the questionnaire. The analysis of the proposed model is done by Partial Least Square (PLS). The results of the analysis provide support to the proposed model that accounting benefits, operational benefits, individual productivity, and managerial benefits are indicators that measure user satisfaction of ERP systems. The expected theoretical contribution of the results of this study is to provide insight into the system user satisfaction model, apart from the practical contribution for ERP provider companies for paying attention to the factors affecting ERP user satisfaction.

Abstract

Network documentation and legal information website is a form of e-government applications such as Jaringan Dokumentasi dan Informasi Hukum (JDIH). JDIH website must be designed to be an effective and efficient information system. This study aims to determine the success factors of the implementation of JDIH website. The DeLone and McLean model and the Unified Theory Acceptance and Use of Technology (UTAUT) are the models used in this study. The case study is conducted in the Riau legal and human rights office. Data are obtained through questionnaires from 252 respondents in the Riau provincial government and some communities. The analysis uses Structural Equation Modeling (SEM) and Analysis of Moment Structure (AMOS). The results of this study show that nine hypotheses have positive effects. Meanwhile, four hypotheses have no positive effects on the success and use of JDIH website. The findings of this research will be used as a reference inthe development of JDIH website in the future.
