Good IT governance can help support the organization's success in achieving its goals. To find out the extent to which IT governance is implemented, IT governance needs to be audited. In its development, IT has been applied in various places, one of which is the University. IT implemented in the University is a concept that answers the needs of the organization to guarantee the return of invested IT. Without IT governance, it can be a waste of IT investment done. XYZ University is one of several universities that have implemented IT to support data services and management. The implementation of IT at XYZ university has never been audited. The purpose of this study was to conduct an audit of the IT governance that was implemented. IT governance audit is carried out based on the COBIT 5 framework. This research uses a descriptive method. Based on the results obtained from the analysis carried out, IT governance at XYZ university is still at the level of capability level 0 - Incomplete Process with the acquisition of capability values averaging 0.5. Researchers provide advice for the University to improve IT governance that has been implemented so that in the future it can achieve a higher level of capability.","PeriodicalId":280589,"journal":{"name":"2020 2nd International Conference on Cybernetics and Intelligent System (ICORIS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133696210","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}

This assessment and comparison is carried out to determine the extent of the effectiveness of advertising promotions and to find out which social media has the highest level of effectiveness in advertising services. Using random sampling, it was found that 60 research samples looked at Micro Small Medium Enterprises (MSMEs) promotional advertising services on Youtube, Facebook, and Instagram. The research stages started from testing the reliability and validity of the questionnaire, determining the scale range of the study in assessing the effectiveness, tabulating the data by looking for the average value of each dimension in the empathy, persuasion, interest, and communication (EPIC) model, then calculating the EPIC rate to determine the effectiveness value of advertisements promoted on social media. The result is that advertisements on the three social media are very effective, seen from the EPIC rate which is on a very effective scale range. EPIC rate for Instagram is 3.3, Facebook is 3.26, and Youtube is 3.28. The highest EPIC rate of 3.3 on Instagram means that Instagram is more effective than Youtube, which is in second place, and the last is Facebook. MSMEs in Palembang are right to choose these three social media as promotional media.","PeriodicalId":280589,"journal":{"name":"2020 2nd International Conference on Cybernetics and Intelligent System (ICORIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129006648","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}

One day the existence of conventional vehicles will be replaced by EV. EV gets electricity supply from batteries. When using EV, one day the electrical energy in the batteries will run out. To recharge batteries, important components such as the Electrical Vehicle Charger (EVC) are needed. EVC provides the impact of voltage drop on the electric power system bus during the charging process. This voltage drop caused by the power supply from generators cannot meet the needs of loads, including chargers and batteries. To maintain the voltage so it remains at its safe operating voltage, the same bus with EVC is interconnected with renewable energy sources. Renewable energy sources used in this study are four types of wind turbine power plants. Safe range of operating voltage in this research from 95% to 105%. This paper analyzes the change in voltage in the electric power system when the wind power plant fills EVC. The research methods section uses several scenarios. The aim is to determine the effect of each type of wind power plant on the bus voltage and EVC. Simulation results show that scenario 3 has the best results than the other scenarios. In scenario 3, voltage in bus 12 is 98,08%, voltage in bus 13 is 98,66%, and voltage in bus 14 is 98,42%. All three buses in safe limits of the operating voltage.","PeriodicalId":280589,"journal":{"name":"2020 2nd International Conference on Cybernetics and Intelligent System (ICORIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133551735","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 the international world, it has been agreed that English is recognized as an international language for people who have different mother tongues, where English is used when communicating in business, political and educational matters between different countries. English is one of the subjects taught at various levels of schools in Indonesia, especially at the junior high school level.

One solves the problem of sound signals disturbed by noise, which can be facilitated by digital filters. The Gaussian method is the best method for eliminating noise in the image developed so that the gaussian method needs to be done to improve the noise in the sound to issue a clean sound signal from noise and increase the noise that has been eliminated. This study uses the Gaussian filter method to filter noise in the sound record. The implementation is divided into two (2) steps to filter on the frequency consisting of images and the second to do with voice recording, in carrying out the filtering on the frequency of the sound that is considered noise. In filtering the Gaussian method to eliminate the noise of the sound record, the current process is combined with obtaining a dynamic range, and peak factor with parameters attack time = 0.01, release time = 0.01, hold time = 0.05, lower limit = 0.0005, and threshold of silence = 0.25.
