Based on data from the Central Bureau of Statistics (BPS) of Riau Province, the annual production of oil palm plantations, especially smallholder plantations in Riau province has always increased. So is the demand for world CPO. But sometimes the selling price of oil palm fresh fruit bunches (FFB) for smallholder plantations always changes due to many influential factors. With the Artificial Neural Network approach, the Backpropagation algorithm we conduct training and testing of the time series variables that affect the data, namely data on the area of oil palm plantations in Riau Province; Total palm oil production in Riau Province; Palm Oil Productivity in Riau Province; Palm Oil Exports in Riau Province and Average World CPO Prices. Then price predictions will be made in the future. Based on the results of the training and testing, the best Artificial Neural Network (ANN) architecture model was obtained with 9 input layers, 5 hidden layers and 1 output layer. The output of RMSE 0000699 error value and accuracy percentage is 99.97% so that it can make price predictions according to the given target value.","PeriodicalId":417247,"journal":{"name":"IJISTECH (International Journal of Information System & Technology)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134040636","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}

An original creation that have been changed for certain purposes will definitely eliminate proof of ownership of the creation. A hash function is one method used to test the authenticity of data, while steganography is one method used to maintain the security of confidential data from outside parties. In this study, the Hash MD5 method will be combined with the Least Significant Bit method to test the authenticity of an image. The purpose of testing the authenticity is to find out the truth of ownership of a creation, in this case, we are testing the image. The results of this test are the status of an image that will be declared valid or invalid. Measurement of validity depends on whether there is a similarity between the value of the Hash that has been implanted and the value of the Hash obtained during the test. If the tested image has the same Hash value, then the image will be declared valid, but instead ai image is declared invalid if the image has been modified or ownership status has been changed. From the result of testing the authenticity with several images, it can prove that the combination of the Hash MD5 method with LSB has a good level of security and suitable to authenticity testing.","PeriodicalId":417247,"journal":{"name":"IJISTECH (International Journal of Information System & Technology)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129812448","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}

Data processing that has been used so far is the Excel application. This, causing data processing requires not a little time and quite a long time. With a system that has long data storage is not safe, especially in the long term. To overcome the problems related to population data, it is designed an application to process the data more easily and safely. The purpose of this study was to determine the effectiveness of the previously designed application of population data in Kresek Village. The study was conducted in Kresek Village, Wungu Sub-District, Madiun Regency. Respondents of this study were 2 Kresek Village officers as users. The analytical method used is descriptive analysis using data from interviews with respondents. Evaluation analysis is carried out to explain the new system that has been implemented. Based on the results of the study, it can be concluded that the application that has been designed is in accordance with the wishes of the Kresek village office. This application is able to ease the workload of village officials so that population data processing is more effective and efficient.","PeriodicalId":417247,"journal":{"name":"IJISTECH (International Journal of Information System & Technology)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129674199","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}

Management is defined as a typical process consisting of planning, organizing, implementing and monitoring carried out to determine and attempt to achieve goals by utilizing human resources and other resources. In the work process of Victory Sorong University, the General Administration Bureau (ADUM) carries out administrative management processes still manually, this can be seen from the survey results that the data management process is carried out in manual books. This is a major issue that needs attention. Manual conditions can support data loss due to several factors.

Harrisma Globaltechnologies Jakarta has not been applied based on virtualization. The problem with cloud storage services in general is that the server is not able to serve a high number of requests as a result the cloud storage server fails. One of these problems is caused by inadequate server resources and less than optimal storage server management. These problems can be solved effectively and efficiently with server virtualization. Where server virtualization is managed by Proxmox. Proxmox is an open-source virtualization platform supported by KVM and OpenVZ hypervisors and can be managed with web-based graphics. Server virtualization collaboration can save server resources by duplicating server services virtually. The research methodology used is clustering by applying the concept of high-availability where there is a secondary server as a backup-server for the primary-server. The results of this study include three parameters, namely Throughput, Response Time, and CPU Usage. The results show that cloud storage servers that implement virtualization than those that do not apply with a difference in the value of the Throughput parameter of 1896.6 Kbps, the difference in the value of the Response Time parameter of 10.6 requests/second, and the difference in the value of the CPU Usage criteria of 11.91%","PeriodicalId":417247,"journal":{"name":"IJISTECH (International Journal of Information System & Technology)","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":"123904546","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}
