It becomes a concern of the government because aside from personal health, this disease also has social and economic impacts since it causes a decrease in productivity. One complication of this disease to the patient is impaired vision is diabetic retinopathy (DR). In order to prevent further development of DR, early detection needs to be performed with routine check on patient's eyes. Clinical features on eye retina that can be used for detection of DR include microaneurysms, hard and soft exudates, haemorrhages, neovazcularisation and macular edema. Segmentation of optic disc (OD) is a very important step to detect these features. This study used red channel from original image based on dispersive phase stretch transform (PST) to detect OD. Final result of segmented optic disc is validated by measuring positive predictive value (PPV). The result shows that PPV for optic disc detection by comparing detected optic disc in ground truth image is 97.74%. This result indicates that the proposed approach successfully detect optic disc and is able to assist the ophthalmologists in analysing retinal fundus image to diagnose glaucoma and diabetic retinopathy.","PeriodicalId":101856,"journal":{"name":"2016 6th International Annual Engineering Seminar (InAES)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128354763","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}

Unequal voltage ratio and short circuit impedance difference between multiple Inter Bus Transformers (IBT) in parallel operation will generate serious problem. Therefore, an evaluation should be conducted before performing parallel operation. This study proposed a brief evaluation of transformer parallel operation using circulating current and load division calculation which was validated by simulation of 3 non identical IBT. Based on the simulation, circulating current flows from IBT with higher secondary voltage to the IBT with lower secondary voltage during load zero crossing and creates phase shift between each IBT's load current toward total loading current. The presence of circulating current will influence IBT's loading current by vector relationship. Unequal short circuit impedance leads to unbalanced load sharing which exceed the tolerance stated in standard. The short circuit current of 3 IBT in parallel operation is very close to the short circuit rating of the installed equipment. Therefore, equal voltage ratio, appropriate short circuit impedance and the short circuit rating of the equipments should be confirmed first before operating 3 IBT in parallel.","PeriodicalId":101856,"journal":{"name":"2016 6th International Annual Engineering Seminar (InAES)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126536438","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}

However, without supervision on temporal patterns of passenger's behavior in Trans Jogja on supply and demand, it will result in the decreases of the number of BRT users and the increasing number of private vehicle users, so that traffic jams remain difficult to avoid. Smart Card Automated Fare Collection System (SCAFCS) which is currently used as e-ticketing in Trans Jogja public transport can be used to analyze passengers pattern with data mining approaches. This paper applied SCAFCS data preprocessing with data warehouse mechanism and implemented Hadoop Platform as distributed computing to improve K-Means++ clustering performance on large datasets scalability; in this case, SCAFCS Trans Jogja has a large dataset (volume) and rapid growth data (velocity). Scalable K-Means++ algorithm generates five clusters with characteristics in number of clusters, namely: Very Low, Low, Average, High, Very High. The clusters were used to analyze passengers pattern based on the dimensions of time (temporal), segmentation of passengers (structure) to determine the variability of passengers based on the card they used and transaction peak on boarding location (spatio). Experimental and testing setup was performed by comparing Sum of Square Error (SSE) which is the total squared error of k cluster at the centroid on three algorithms, simple K-Means, K-Means++ and K-Means++ implementation using Hadoop Platform as parallel and distributed computing. K-Means++ with Hadoop Platform implementation generates smaller SSE value than simple K-Means and K-Means++ algorithms; that shows it has good SSE value.","PeriodicalId":101856,"journal":{"name":"2016 6th International Annual Engineering Seminar (InAES)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124658852","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}

Profit organisations in developed countries have been comprehensively mature in adapting environmental and social sustainability in response to the consciousness of the society with regard to sustainable business. Since production-sites have been shifted to developing countries in the last three decades, nowadays enterprises in developing countries urge to implement planet and people sustainability indicators into their business operations. This research aims to instigate sustainability practices with respect to environmental, social, and economic aspects which are initially employed in the business performance of enterprises from developed nations in order to underline the opportunities for their implementation in developing countries. Empirical evidences is used to unveil people, planet, and profit sustainability criteria linked to supply chain management with a view to compare and contrast such criteria in business practice implementation.

Nevertheless, it is possible that some of enthusiastic users attempt to receive it in mobile environment. Therefore, formulating a technique for improving the reception quality is necessary, and exploring the received signal properties will be useful to do it. This paper presents quantitative-relationships in the received signal explored from field-observation result. The result informs that pairwise relationships between recovered picture and signal describing quantities, as well as among these quantities themselves, are more appropriate expressed probabilistically than mathematically. These quantities include CNR (carrier-to-noise ratio), pre-LDPC (low density parity check) decoding BER (bit-error-rate), and post-LDPC decoding BER. As numerical examples: (1) CNR border between successful and failed receptions is as high as about 14 dB, and (2) for probability of reception-success is as high as about 0.5, the border of these three quantities are about 18 dB, 4.5 × 10−2, and 10−5, respectively.","PeriodicalId":101856,"journal":{"name":"2016 6th International Annual Engineering Seminar (InAES)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125834148","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}
