An existing control method, robust linear quadratic regulator (RLQR), was applied to control the inventory level by generating the optimal purchasing product volume so that the product stock follows a reference trajectory with minimal cost. The result of the performed numerical experiments showed that the optimal purchasing product volume was determined for every time period and the product stock was closed to the given trajectory level desired by the decision maker.","PeriodicalId":438473,"journal":{"name":"2018 2nd International Conference on Informatics and Computational Sciences (ICICoS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126406572","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}

In this paper, we are interested to build a new procedure using rough-regression model in determining the dominant criteria from each factor based on generalization of dependency attribute. Based on result, the proposed procedure is capable to investigate the dominant criteria and factors affecting student achievement, such as, language spoken with dominant criteria is “many-many”, FB friend with dominant criteria is “many” and fast food with dominant criteria is “never”. This proposed procedure is very appropriate to implement for handling categorical data.","PeriodicalId":438473,"journal":{"name":"2018 2nd International Conference on Informatics and Computational Sciences (ICICoS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132696725","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}

The organization places IT as a matter that can support the achievement of the company's strategic plan to achieve the goals of the company's vision or mission and goals, as well as the Faculty of Science and Mathematics of the Diponegoro University (FSM UNDIP). FSM UNDIP has a vision to become a superior faculty based on research in the fields of science and mathematics and the development of its application. And one of the missions to achieve this vision is Enhancing governance efficient, accountable, transparent, fair, and integrated between sectors (good governance). IT governance in an organization aims to align IT strategy with the organization's business strategy. Without good and right governance, IT will cause problems and threats to the organization. This research aims to assess the capabilities of the IT governance process at FSM UNDIP. The framework used to assess IT governance that focuses on web-based services in FSM is this study using COBIT 5 on EDM03 and EDM04 domains, with the Self Assessment method. The results showed that the capability level of the IT governance process at FSM UNDIP in the EDM03 process was at Level 2 (Managed Process), which is an organization in carrying out IT, at this stage it has been successful and governance has been done well. Management of the planning, evaluation and adjustment processes is directed to better direction. While the EDM04 process is at level 1, the organization has successfully implemented IT processes and the goal of the IT process has been successfully achieved. The results provided are documents containing the governance of Risk Optimization and Resource Optimization management as a basis for risk and resource management references on the FSM UNDIP website.

The problem is getting harder when the dataset has multiclass target and the number of samples in each class is not well distributed (which is called imbalance data distribution). In this research, two different approaches to handle imbalance data distribution are studied, they are SMOTE (based on data approach) and weighted ELM (based on algorithmic approach). To evaluate the performance of the proposed method, two public imbalanced multiclass microarray dataset are used, GCM (Global Cancer Map) and Subtypes-Leukemia dataset. The results of experiment show that the implementation of SMOTE and weighted ELM on GCM dataset have no significant effect in the classification performance. Different with the Subtypes-Leukemia dataset, the implementation of SMOTE and weighted ELM has improved the classification performance compared to the previous research. Generally, the results show that weighted ELM perform slightly better compared to SMOTE to increase the accuracy of the minority class.","PeriodicalId":438473,"journal":{"name":"2018 2nd International Conference on Informatics and Computational Sciences (ICICoS)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128751577","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}

The variations created by each person in writing the characters affect the character recognition result. Many studies have been performed to increase the performance of Javanese character recognition. The efforts are to extract the best feature for classification or to get the best classifier for classification. In this study, HOG feature and Zoning Based Feature will be used to classify Javanese Characters. The performance of both features will be compared for classifying Javanese character by using SVM classifier. Two types of inputs will be used for each feature extractor, binary and skeleton of the character image. The experiment showed that HOG feature is able to show higher accuracy as compared to the simple zone based feature (88.45%). The best accuracy for HOG is achieved by using binary input. On the other hand, despite its simplicity zone based feature is able to achive 81.98% accuracy by using skeleton input. Considering that the zone based feature used in this research is simply the pixel count in each zone, future research may be performed to extract more statistical properties on each zone. Future works may also focus on rotation free feature extraction for Javanese character classification.","PeriodicalId":438473,"journal":{"name":"2018 2nd International Conference on Informatics and Computational Sciences (ICICoS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117127548","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}

With the help of image processing and artificial neural network, recognition of 13 commonly used hand signals is implemented. The significance of this study is with regards to the extension of the capabilities of a machine to interpret commands or meanings of signals. This adds to the probability of assurance of safety of divers especially when their voice equipment fails. The aim is to show the conformity and effectivity of relating underwater communications, image processing utilizing Hu-Moments as feature extraction method, and neural network. The results are shown through graphical representations of correlation coefficients, errors and success rates of pattern recognition.
