Power flow analysis is needed in the feasibility study of the PV system installation. In this study 300 kW solar power capacity was selected in the simulation of power flow analysis to evaluate the best system states. The results of the study using four cases show that the best voltage profile is obtained in conditions where the PV system is placed on the bus which have lowest voltage and on the load bus which farthest from the source. All load bus voltages have increase above 0.9 p.u in this case and and the lowest voltage within SPLN standard. The lowest level of losses of 55.429 kW is obtained in case three where PV is placed only on buses with the lowest voltage value. Power losses are obtained far below 10% as the losses permitted according to the PLN standard. Therefore, The integration of PV system into an Unand distribution network can improve the voltage profile and reduce total system losses.","PeriodicalId":131994,"journal":{"name":"2019 3rd International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126773432","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 company uses a flow shop system and the demand type is make to order. In the scheduling system the company currently uses First Come First Served (FCFS). The company still finds an improper quantity schedules, which results in a large amount of makespan and causes inaccurate product delivery schedules for consumers. The study was conducted to find the optimal sequence of scheduling with makespan minimization criteria by the genetic algorithm method and FCFS method comparison. The FCFS method used by the company produces makespan of 55,970 hours when the Genetic Algorithm method produces makespan of 46,637 hours. The recommendation method has a better performance level compared to the company shown in efficiency index (EI). The EI value of the Genetic Algorithm method is 1,20 (EI> 1) which shows that the Genetic Algorithm has good performance compared to the FCFS method. The calculation of the value of Relative Error (RE) shows that the saving of makespan obtained by the Genetic Algorithm method with the FCFS method is 20,13%. The conclusion is that the Genetic Algorithm method produces the minimum makespan value with a reduction of makespan of 9,33 hours. The schedule obtained using the Genetic Algorithm method is Job 2 - Job 3 - Job 1-Job 5 and Job 4. Job on the floor based on products section that produces in this industry.

The method used is a combination of Local Binary Pattern (LBP) and Convolutional Neural Network (CNN) methods which can later be used as sensors or vision for skin diseases automatically. The results of this study can help in the early identification of skin diseases, helping parties who want to know the image value of skin diseases by using LBP and classifying it based on the type of disease using CNN. This study shows the level of accuracy of combining LBP with CNN is quite high with an average value of 92%.

The optimal design was obtained by analyzing the changed of feed line position and truncated corner size of the patch. The initial design was performed theoretically, then simulated using the AWR simulator and measured experimentally. Measurement results using a vector network analyzer show that the antenna design achieves the return loss of −26.04 dB and VSWR of 1.1 at frequency of 1575 MHz.

The clouds cumulonimbus shows some irregular and undefined phenomena called chaos. However, in order to make sure that a chaos phenomenon will lead to the occurance of tornadoes, some criteria and characteristics should be fulfilled. One of such criteria is an extreme heat that is caused by the formation of clouds cumulonimbus. On the gray color edge of the cumulonimbus clouds there are some conditions that characterize the image such as wavelength, frequency and the intensity of the colors in clouds cumulonimbus images, as well as the different levels of the brightness and darkness. In addition, color of the image could be used also as a basis to define the parameters related to the start condition of the tornado. In this research, edge detection algorithm is used to get the gray edge boundary, with mean to extract the intensification of irregular patterns on cumulonimbus clouds in order to automatically predict the occurrence of tornadoes.
