Selecting different spatial weight matrix for the same analysis method will eventually generate different results. The commonly used scenarios to create spatial weight matrix are contiguity based and distance based. However, these scenarios have their own problems. Contiguity based scenario like Queen and Rook has disadvantages of forming unconnected neighbours especially for sparse region like islands. Meanwhile, distance based scenario needs specific input parameters, which often requires exhausted trials or expert judgement to specify the parameters. For distance based k-Nearest Neighbours, the result will be asymmetric weight matrix that cannot be used for two-way interaction analysis. To overcome these problems, we propose a Dynamic Nearest Neighbours (DNN) algorithm. It uses different types of distance, which are coordinate distance and attributed distance. In the evaluation, DNN algorithm outperforms other techniques of Rook, Queen, and Α-Nearest Neighbours since it can be applied to both contiguous and sparse regions and produce two-way relations.","PeriodicalId":267924,"journal":{"name":"2016 International Conference on Advanced Computer Science and Information Systems (ICACSIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are cheaper and more solid controller which is button-based remote control, however it has enormous buttons that are confusing. This paper proposes a development of button-based remote control which is equipped with simple LCD screen. The LCD screen is accessorised in the remote control to reduce number of buttons and give visual feedback to users. The remote control is utilized for simple on-off operation and dedicated for Indonesian users. Its design method apply Interaction Design Method as guidance to maximize its usability. The method consists of following steps: (1) What is wanted, (2) Analysis (3) Design (4) Prototype, (5) Implementation and Deployment. The prototype was build using Arduino Nano as microcontroller, small LCD screen and push button switches. The remote control was first tested in functionality for design verification and it shows good performance to comply every given tasks. Afterward, user-participation test was conducted with 30 respondents. Based on the observation of user performing 8 tasks of swithcing on and off four smart home devices (gate, lamp, sprinkle and electronic devices) using the developed remote-control for the first time, average excecution time for each task is 9.2 seconds. Furthermore, USE quistionnaire given to users after experiencing the remote-control showed that its usability in terms of usefullness, satisfaction, ease of use and ease of learning achieved mode of grade 4 in 1–5 Likert scale.","PeriodicalId":267924,"journal":{"name":"2016 International Conference on Advanced Computer Science and Information Systems (ICACSIS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125938121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are around 5 million SMEs in Indonesia, but only about 75 thousand are already using e-commerce which means that the adoption of e-commerce by SMEs is still relatively low. Hence, this research aims to investigate what are the supporting and inhibiting factors for sellers (SMEs) in adopting e-commerce. The initial list of factors from the literature review are validated by 11 experts which resulted 25 supporting and 17 inhibiting factors grouped by using a combination of TOE framework and UTAUT model, namely I-TOE framework. Then, we distributed questionnaires on the basis of Fuzzy-AHP to rank the factors. The results show the top supporting factors are “Perceived ease of use”, “Technology infrastructure available”, “Customer communication improved”, and “Encouragement from environment culture” while the top inhibiting factors are “Perceived no benefit gain”, “Supporting infrastructure unavailable”, “Lack of business compatibility”, and “Vendor less friendly to customer”.","PeriodicalId":267924,"journal":{"name":"2016 International Conference on Advanced Computer Science and Information Systems (ICACSIS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125817621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This process takes time and costly. Hence, automatic essay scoring is needed. Since the scoring system will be integrated to the e-learning, we need a computationally lightweight method that still does not rule out the accuracy of the assessment. In this paper, we propose an automatic scoring system for essay examination using unsupervised approaches. We compare and analyze two similarity measure methods, cosine similarity and latent semantic analysis. The parameters that was used to measure the performance of the methods are the computational complexity — measured by the amount of CPU and memory usage, and page load time — and accuracy — measured by Pearson Correlation and Mean Absolute Error. The results showed that both algorithm consumed same amount of memory. For CPU usage, LSA consumption is 0.13% and cosine's is 0.06%. For page load time, cosine similarity is faster than LSA which is 0.2 second and 0.5 second consecutively. Based on the correlation measure with Pearson, LSA is more superior to the cosine similarity by 0.59 to 0.49. LSA also has less MAE than cosine similarity which is 5.69 compared to 5.33. From that result, LSA and Cosine Similarity has a very competitive result in accuracy. However, Cosine has a better server performance so that preferred to be implemented in e-learning automatic essay scoring system.","PeriodicalId":267924,"journal":{"name":"2016 International Conference on Advanced Computer Science and Information Systems (ICACSIS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128263528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
