Of the 250 million population, there are only 1160 opthalmologist with uneven distribution. Cataract is one of disease such as macula degeneration, diabetes retinopatty. In this paper, classification of cataracts is divided into 4 normal retina, mild cataract, medium and severe. the classifier-making procedure includes four parts: pre-processing, segmentation, feature extraction, and classification. pre-processing using HSV to search for the highest level of light intensity, GLCM is used on feature extraction to obtain features that will be used to classify using Network Backpropagation that has great potential to improve the diagnostic efficiency diagnostic accuracy. In this research use image processing in detecting cataract characteristic in fundus image based on opacity level of optic disc. The data used were 60 retinal fundus images consisting of 15 normal retinal images, 15 light cataract images, 15 medium cataract images and 15 severe cataract images. The result of simulation test using MATLAB R2014a software obtained the normal retinal grade accuracy value of 95.71% with 95.7% sensitivity and 96.15% specificity, mild cataract 69.97% with sensitivity 69.97% and specificity 89.47%. Accuracy of medium cataract class is 75.69% with sensitivity 75.69% and specificity 92.75%. The accuracy of severe cataract class is 87.13% with sensitivity 87.13% and specificity 98.56%. The average accuracy value of the cataract classification system was 82.14%.","PeriodicalId":127106,"journal":{"name":"2020 2nd International Conference on Industrial Electrical and Electronics (ICIEE)","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128488429","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}

Meanwhile, if it is exorbitant, it will cause over-investment and incriminate investment cost. Existing method of sector load is simplified and easy to implement. However, the accuracy tends to bias over one area of which data is limited and dynamic service area. Besides, the results of its forecast is macro-based, which means it is unable to show load centers in micro grids and failed to locate the distribution station. Therefore, we need micro-spatial load forecasting. By using micro-spatial load forecast, the extrapolated areas are grouped into grids. Clustering analysis is used for grouping the grids. It generates similarity matrix of similar data group. Clustering involves factors causing load growth at each grid; geography, demography, socio- economic, and electricity load per sector. Results of every cluster consist of different regional characteristics, which later the load growth is projected as to obtain more accurate forecast.","PeriodicalId":127106,"journal":{"name":"2020 2nd International Conference on Industrial Electrical and Electronics (ICIEE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126024781","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}

To overcome these problems, Photovoltaic (PV) technology has been developed. But, the characteristics of the PV output power depending on the intensity of the existing sunlight, so it can cause instability in the system. This instability can be minimized by combining a PV system with a battery. This study aims to conduct transient stability analysis on the Baubau power system when a 10 MWac hybrid PV-battery power plant is added. In this study, the power flow and stability analysis of the Baubau system was simulated using ETAP software and the energy mix from power plants was simulated using Homer Pro software. From the simulation result can be concluded that installation of 10 MWac PV + 4 MWh batteries in the Baubau System did not harm the overall system stability. The hybrid system can increase the power capacity and installed power of the system.","PeriodicalId":127106,"journal":{"name":"2020 2nd International Conference on Industrial Electrical and Electronics (ICIEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129540158","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 use of PV technology is not only limited to ground mounted with utility scale but also PV rooftop for resident especially in urban areas. However, factors like near shadings could reduce the performance of this system by producing irradiance loss. Dense buildings like in many urban areas may trigger this kind of loss. This paper evaluates the performance of a PV rooftop system due to such shading with a case study 1.5 kWp installed in Jakarta, Indonesia. System simulation theoretically calculates the energy variation produced in a year. As a result, The energy loss is about 2.3% - 2.6% caused by near shadings at STC.","PeriodicalId":127106,"journal":{"name":"2020 2nd International Conference on Industrial Electrical and Electronics (ICIEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128957227","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}

Besides, most of the old diesel power plants in Indonesia is still use High-Speed Diesel (HSD). In order to decide if the old diesel power plant is still feasible from the technical and economical point of view, a detailed analysis should be done. This paper proposes a model management tools to determine its techno-economic feasibility analysis from some factor such as cost, reliability, availability and economic life. This paper also propose the modeling calculation of Cost of Electricity (COE), Life Cycle Cost (LCC) and Equivalent Uniform Annual Cost (EUAC) methods to determine in techno-economic. A simple case study is discussed. The result recommends for asset retirement without abandonment for the old diesel power plant and replacement with the new Power Plant using a dual fuel engine (Gas Fuel and Marine Fuel Oil (MFO)). From the new power plant, it also can be estimated the replacement should be carried out in 14th year for the future. Finally, model management tools can be used to facilitate decision making in similar cases in the diesel power plant.","PeriodicalId":127106,"journal":{"name":"2020 2nd International Conference on Industrial Electrical and Electronics (ICIEE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128826336","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}
