Starting in 2016 Karimunjawa Island is supplied by 2 units of Legon Bajak Diesel Power Plant (PLTD) with a capacity of 2x2.2 MW. Based on the peak electricity demand on Karimunjawa Island, each month from January 2017 to December 2018 increased by about 3.9% with an hourly peak load of 1,146 kWh. The average consumption of PLTD Legon Bajak every month in 2018 is 194,877 liters / month. The higher the kWh production of a PLTD, the higher the operational costs for fuel. In addition to the high price of fuel, combustion results from PLTD operations also cause air pollution. Based on these problems in this study will analyze the optimization of the kWh Legon Bajak PLTD using a wind turbine generator model b.ventus 250 kW of 3 units with an assumption of 50% of the peak load, because on Karimunjawa Island has a high enough wind energy potential. The average wind speed from 2004 to 2015 in several areas of Karimunjawa Island was 5.7 m / s. In this study will calculate technical analysis and economic analysis. In the technical analysis the wind turbine generator power output is calculated using the weibull method based on wind speed and power curve b.ventus 250 kW while the economic analysis calculates the cost of fuel savings that can be achieved after optimization calculations. Calculation results show wind turbine power output of 990,981 kWh / year. Based on the specific value of fuel consumption (SFC) of 0.432 liters / kWh fuel consumption during 2017 amounted to 1,605,453.9 liters / year while for 2018 it was 2,338,528.1 liters / year. From the 3 wind turbine electricity supply of 2,972,943 kWh / year, it will reduce fuel consumption by 1,284,311.4 liters / year with a saving cost of Rp.15,989,291,338.00. The amount of optimization of the kWh PLTD after the supply of 3 units of b.ventus 250 kW wind turbine model in 2017 was 80% while in 2018 it was 54.9%.","PeriodicalId":31717,"journal":{"name":"Simetris Jurnal Teknik Mesin Elektro dan Ilmu Komputer","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77849353","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 current conventional outlet, although it has been standardized by the Indonesian national standard, is a fact in the field that there are still many incidents of electric shock, because the voltage continues to flow through the copper terminals inside the plastic frame protector. This incident can occur because the terminal is plugged into a conducting object such as a fork, spoon, iron rod, or held directly with a finger. For this reason, in this study, a safety system is made that uses the main component of the Relay as an intermediary for DC voltage and AC voltage. Trials carried out 50 times on each socket box resulted in solving the problem by conditioning the plug that had not been plugged into the terminal so that there was no voltage flowing into the outlet, this certainly distinguishes safety from using an ELCB which must have contact with the human body first.","PeriodicalId":31717,"journal":{"name":"Simetris Jurnal Teknik Mesin Elektro dan Ilmu Komputer","volume":"7 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72387214","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 campus, which was founded in 2016, is now getting busier, both because of the increasing number of students from year to year, as well as the number of employees working there. This raises problems, one of which is related to the reservation (borrowing) of several rooms that can be used freely, both for lectures and meetings. Previously, recording room reservations was still done manually using paper. In addition, recording reservations is also not flexible because someone must to go to an authorized employee to record reservations. To adapt to the challenges of the digital era and the green economy, it is necessary to reduce the use of paper (paperless) by building a website-based room reservation system where users can make reservations that can be accessed in real-time anytime and anywhere. The research method used will apply the principle of object oriented programming. The system was built using the PHPRad framework with system implementation carried out at the Shanti Bhuana Institute.

The use of the internet in the computer network of SMAN 47 Jakarta is a very large number of students and teachers. Computer networks in schools are provided not only to support the teaching and learning process but also to support the very high mobility of the learning community. Of the many teachers, staff and students at SMAN 47 Jakarta who are active internet users, some users download (using the Download manager), and some use it for browsing, running YouTube, Twitter, Instagram applications, and so on. . With limited bandwidth and no regulation of bandwidth usage, causing unfair and equitable distribution of bandwidth, bandwidth management is carried out using the simple queue method, as well as to make it easier for network administrators to configure. The success of bandwidth management is carried out through Quality of Services (QOS) with indicators: throughput, jitter, packet loss and delay. The value used as a barometer of QOS success is the THIPON index. From the test results of the proposed system made by the author, a case study in the Lab room, that the implementation of bandwidth management with the simple queue method resulted in a score of 4 THIPON indexes on all measured QoS indicators. Through this bandwidth management, network administrators can provide guarantees to users on the availability and fairness of bandwidth usage according to the user's priorities and needs. It is necessary to make a Standard Operational Procedure (SOP) regarding the bandwidth management mechanism so that bandwidth management can be carried out in accordance with the standards and carried out by whoever is the network administrator. ","PeriodicalId":31717,"journal":{"name":"Simetris Jurnal Teknik Mesin Elektro dan Ilmu Komputer","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79445168","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}
