Automobile companies are one of the many industries that exist in various countries. This is because automobiles are transportation products that are widely used both for the purpose of transporting people and goods. Poor production machine performance will disrupt internal productivity to the point that it will affect the stability of industrial profits. One of the factors causing poor engine performance is due to predictive maintenance analysis activities that are still not optimal. SCADA system development will focus on monitoring equipment before it becomes abnormal (predictive maintenance) in real time. The monitoring and control method is carried out automatically by using sensors for data retrieval and a programmable logic controller as a remote terminal unit. Then, data will be sent to the server via CC-Link IE Field Communication and later be recorded and analyzed through the SCADA display. The results of research optimizing engine performance using the SCADA system are effective, with an increase in engine performance of 96.2% for downtime and 97.0% for frequency trouble.","PeriodicalId":166066,"journal":{"name":"ENERGI & KELISTRIKAN","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129346420","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}

Energy conservation is the obligation of all parties, including from the side of energy users in buildings, including one of them is the ITERA Public Lecture Building which is used mostly for classrooms, but there is no data on the quality of the lighting system. Therefore, this study aims to analyze the lighting system (energy consumption and lighting level) on the 3rd Floor of the ITERA General Lecture Building using the energy audit method. From the results of the study, it was found that the total energy consumption in the artificial lighting system (lamps) was 798.72 kWh/month, and the lighting level met the minimum limits of SNI 6197-2020, but out of 11 classrooms there were 7 rooms that were too much larger than SNI 6197-2020. So that the saving opportunity that can be done is to change the awareness of room energy users by reducing the length of time the lamp is used and prioritizing the use of natural light in the morning and afternoon so that it can save energy use by up to 34%.","PeriodicalId":166066,"journal":{"name":"ENERGI & KELISTRIKAN","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133891336","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}

PLN Indonesia Power Priok is used as a heat exchanger to reduce the temperature of the lubricant that has passed through the system so that it can return through the system at a lower temperature. CCPP Block 1-2 often experience Start-Shutdown units due to requests from the PLN load regulator, therefore the lube oil cooler fan often continues to operate even though the lubricant temperature is low during the Shutdown (RS). The lube oil cooler fan optimization program is an activity to turn off one fan during the reverse shutdown unit and turn off all the fans manually by the operator when the lubricant temperature is below 42oC and then recorded for documentation. This activity is contained in the Standard Operating Procedure regarding energy saving during RS Gas Turbines. With the existence of an optimization program for operating patterns by turning off the lube oil cooler fan, it is hoped that it will be able to reduce power, with the target of reducing electric power consumption by 40,000 KWh per year. This program can save 165,454.34 kWh of power in 2020, or the equivalent of 595.64 GJ, and in 2021 it can save 101,468.40 kWh of energy, or the equivalent of 365.29 GJ.","PeriodicalId":166066,"journal":{"name":"ENERGI & KELISTRIKAN","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114080086","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}

There are seven step output voltage levels that are close to a sinusoidal shape, but still contain high levels of harmonics.

To optimize the function and operation of the Motorized LBS, it is necessary to integrate the SCADA system so that it can be operated remotely. In this integration process, one of the important components needed is the Remote Terminal Unit (RTU) which functions as a device that provides information about the equipment and carries out orders (teleinformation), but to achieve this we are constrained by the very expensive price of the RTU. For this reason, an alternative remote terminal unit is needed as a substitute for the RTU which represents the function of the RTU on the scada system itself.
