Temporary Tower is used as a tool in reconductoring work and tower replacement. The study by calculating the Budget Plan Cost (RAB) and schedule analysis using Microsoft Project Application to determine the comparative duration of time required to complete the reconductoring work and tower replacement between using temporary tower and without temporary tower. From the time schedule created, it will be known which work method uses a shorter duration of time so that it can save or speed up the outage time. This study will produce what kind or type of conductor is appropriate in the context of replacing conductors or reconductoring SUTT 150 kV A - C, resulting in a reconductoring and tower replacement work schedule that is 15 days faster when using a temporary tower and reduces the outage time by about 132 days or about -89%. However, it requires an additional cost of Rp 1,872,217,454, which is still much smaller than the loss due to outages if the work is not done with a temporary tower.","PeriodicalId":33739,"journal":{"name":"Rekayasa","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135183029","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 alternative that can be used to determine the condition of ocean currents is to use hydrodynamic modeling. The purpose of the study was to analyze the distribution pattern and characteristics of surface ocean currents. This research was conducted by conducting 2-dimensional hydrodynamic modeling simulating ocean currents for 1 (one) year in December 2020-November 2021 using MIKE 21 software by sampling in 6 (six) different conditions, namely at the highest tide, lowest tide, high tide. towards the ebb and flow of the full moon, the ebb towards the negligible tide, the tide towards the ebb tide and the ebb towards the negligible tide. The model results were validated by the RMSE formula with a value of 2%, the model results were very good, so that they could be used as a reference in providing an overview of the real conditions of the pattern and current distribution at the research location. The movement of ocean currents at the time of the full moon and negligible dominant currents move towards the south of the waters, while at the time of the full tide and negligible the dominant currents move towards the north of the waters. In the north season, the current velocity ranges from 0.00006 m/s-0.125 m/s with the dominant movement towards the north. East monsoon currents move predominantly north and south with speeds ranging from 0.0000003 m/s-0.129 m/s. In the south monsoon the dominant current moves to the north and south at a speed of 0.0000007 m/s-0.13 m/s. in the west season, the dominant current moves to the north and south at a speed of 0.00001 m/s-0.12 m/s. The speed of the dominant ocean currents is greater at high tide compared to low tide, this is due to differences in sea level elevation in the opposite direction of motion.","PeriodicalId":33739,"journal":{"name":"Rekayasa","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135354374","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 challenge of agriculture today is to meet the increasing need for food with limited land and uncertain plant microenvironmental conditions, one solution to this problem is planting using a plant factory system. Fuzzy logic has an effective method for controlling plant factory control systems, due to its flexibility and simple calculations. The purpose of this research is to find the PWM value in the plant factory control system that suits the optimal needs of pak choy vegetable cultivation. There are 4 stages in the research, namely the primary data input of the LED plant factory, Fuzzyfication, Fuzzy Interface System and Defuzzification. Data was taken using a lux meter and there were a total of 56 fuzzy rules and 4 fuzzy rules that did not have a value of 0.

The strain values resulting from the BISAAR 3.0 program analysis in the form of asphalt mix horizontal tensile strain (ε t ) and subgrade vertical strain (ε z ) are used to calculate the life of flexible pavements. The results of the analysis show that when using fatigue crack damage criteria, a temperature increase of 5.8% will cause a decrease in the life of flexible pavement by 0.7% (critical condition) or 0.6% (failed condition).
