Event logs can be valuable information with a technique called mining process. With this technique, cheating on the business processes of an enterprise can be detected early on. Thus, the company can commit further examination of business processes, especially the business process of procurement of goods and services to achieve business process is expected.[8] In this study, management data of event log obtained from log data at each event transaction procurement and services. The event log data is then analyzed using a heuristic miner algorithm. Heuristics miner algorithm chosen because it has advantages that are not owned by Alpha++ algorithm that this algorithm can calculate the frequency relation between activities in the log to determine the causal dependency. Heuristic Miner can be used to determine the predominant process of thousands of logs and detect behaviors that are not common in a process.[11] This study aims to detect anomalies on business processes that occur during the process of procurement of goods and services by calculating the fitness value of the event log into the system.

Early detection of the disease is required in order to be able to prepare preventive measures against dengue fever. Previous research has shown that certain query search related to communicable disease on Google Trends are highly correlated with number of communicable disease cases in South Korea. Based on previous research, Google Trends search index shows potential to be included as external variable in a multivariate quantitative forecasting model. Using time series model, the role of Google Trends on epidemiology of dengue fever transmissions in Surabaya will be analyzed. This research uses several data (1) Number of dengue fever cases obtained from general local hospital of Dr. Soetomo (2) Google Trends search index of certain queries related to dengue fever. All of the data spans from December 2010 – August 2015. Interpolation and extrapolation techniques are used to handle the missing data. ARIMA and ARIMAX model with Google Trends data are implemented in order to forecast the number of dengue fever cases. The research shows that the addition of Google Trends into ARIMAX model improves forecasting performance. The best ARIMAX with Google Trends model improves MAPE value by 3%.","PeriodicalId":177275,"journal":{"name":"2016 International Conference on Information & Communication Technology and Systems (ICTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130625094","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}

Exudates segmentation is ordinarily examined from retinal fundus images by various image processing techniques. Instead of carefully picking up the specific exudates features on the retinal images as has been done by the other works, our scheme is to observe global information of the retinal images. The global information, as well as spatial information, is extracted by maximum entropy-based thresholding. The proposed algorithm determines a reasonable threshold value for separating exudates areas, which are usually sparse and brighter, from the rest of images. This approach also ensures and minimizes the illumination variance effects of different images since it takes into account the global information. In addition to the proposed algorithm, luminance channel of the retinal images is exploited for pre-processing stage. After the optical disc which has similar characteristic to the exudates is separated, the pathological areas are subsequently acquired. Evaluations on the E-OPHTHA-EX retinal fundus images database show the advantages of the proposed approach, with the accuracy 99.4 percent, specificity 99.6 percent, and sensitivity 16.9 percent.","PeriodicalId":177275,"journal":{"name":"2016 International Conference on Information & Communication Technology and Systems (ICTS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125406616","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}

Actually, since 2003, passenger terminal capacity already exceeded two times capacity allowed. To solve this problem, this research proposed new modeling-simulation-dynamic-system, that combine between GDP, population, terminal capacity and regulation from minister of transport to forecast passenger demand and time to expansion the airport. Simulation model utilized historical data in 2005–2015 to generate forecasting for 2016–2050. There were three scenarios used as consideration in determining policy, such as pessimistic, most likely, and optimistic scenario. In the pessimistic scenario models, the ideal for development is before 2031. In the most likely scenario models, the ideal time for development is before 2025.

This websites also give information to the citizen about response of government toward the proposals which are uploaded by citizen. However, the status of the proposals cannot be monitored by citizen using the website. Therefore, a web application Monitoring dan Visualisasi Musrenbang or called Monvis-Musrenbang is developed to facilitate a citizen in terms of monitoring and tracking their proposals. The more citizen participate in giving feedback, the more accurate the information are. The web application should increase and maintain the citizen activity in giving the feedback. Thus, a gamification is implemented over the web application. The gamification system is designed based on User-centered approach. A user earn points after doing an activity or completing an event. The activity and event are formulated clearly in this paper. A group of people are asked to do set of activities before and after the gamification implementation. The evaluation results reveal that the gamification design can stimulate a citizen to do an activity without changing his motivation.","PeriodicalId":177275,"journal":{"name":"2016 International Conference on Information & Communication Technology and Systems (ICTS)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124571789","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}
