Abstract

The development of electric vehicles is growing rapidly, including electric motorcycles as a solution to overcome the energy crisis and reduce air pollution that occurs. One important aspect is when braking and speeding which can affect the current and voltage in the vehicle's electrical system. This study aims to determine how much influence is produced when braking and speed on current and voltage. This research uses a simple regression analysis method using statistical modelling through SPSS. The results showed that there was an influence of braking and speed on the value of current and voltage produced. When braking with EBS variations of 4%, 8%, and 12% the R Square value is 96.40%, 99.80%, and 99.30% of the current. As for the voltage, the R Square value is 93.70%, 72.30%, 87.70%. The braking results of 4%, 8%, and 12% EBS variations at a speed of 10 km/h produce a current of 0.1 A, 0.5 A, 0.8 A and produce a voltage of 77.33 V, 78.47 V, 78.46 V. At the time of speed, the R Square value is 99% of the current and the R Square value is 96.20% of the voltage. Results with a speed of 10 km/h require a current of 13.5 A and produce a voltage of 77.86 V.  This study shows the influence between braking conditions and speed on current and voltage in electric motor vehicles.

Abstract

At PT PLN (Persero) UP3 Palembang, especially the Kenten area in the feeder distribution system, there has been a drop voltage and is almost close to the applicable standard threshold. So preventive efforts are needed so that the drop voltage situation does not worsen. It was recorded that there had been  the highest drop voltage in the Beo feeder by 3.05%, in the Kacer feeder by 2.6%, the Pipit feeder by 2.35%, the Merak feeder by 2.3%, and the Foil feeder by 2.3%. This is a problem that should be able to be improved. In this study, a simulation  of drop voltage  repair will be carried out with the help of  ETAP 12.6 software, which will describe a single line diagram with the results  of load flow analysis in the form  of drops that occur, with the authenticity of the data obtained as the simulation results show the real state of the field. In the simulation of repairing the drop voltage using  the Conductor Uprating  method for the repair of the drop that occurred in the feeder, after the repair was made, the drop voltage that occurred decreased in the Beo feeder by 1.705%, in the Kacer feeder by 1.69%, the Pipit feeder by 1.48%, the Merak feeder by 1.315%, and the Foil feeder by 1.24%.

Abstract

This research investigates the reliability of Kediri Subsystem 3,4, focusing on the impact of a Manisrejo-Nganjuk Transmission Line trip on Manisrejo-Caruban Transmission Line under normal and N-1 contingency conditions. Using Digsilent 15.1, load simulations were conducted revealing that under normal conditions, Manisrejo-Caruban Transmission Line operates at 88.92% capacity. A trip on Manisrejo-Nganjuk line could potentially overload Manisrejo-Caruban line, failing N-1 contingency requirements. To address this, Overload Shedding (OLS) was implemented on the Manisrejo-Caruban Transmission Line. Simulation results post-OLS implementation showed a reduction in line load to 64.99%, necessitating an OLS setting addition of 435.6 A. A two-stage OLS strategy was adopted: the first stage targeted OLS release at Nganjuk Substation Transformer 1, followed by the second stage at Caruban Substation Transformer 1. This effectively reduced the Manisrejo-Caruban Transmission Line load to 58.1% of its capacity. Economically, PT. PLN (Persero) benefited significantly from this implementation, saving Rp. 42,170,793 in costs. These findings underscore the efficacy of OLS strategies in enhancing system reliability and mitigating overloads, thereby optimizing operational efficiencies and cost savings for power utilities.

Abstract

Clean water is one of the targets in the Sustainable Development Goals (SDG's), specifically ensuring the availability and sustainability of water management. Continued use of groundwater results in land subsidence. The high level of rainfall in Jakarta requires rainwater to be utilized to reduce surface water runoff, especially by rainwater harvesting. PLN Institute of Technology has a total of more than 3.000 employees and students. Based on the use of non-domestic water needs in universities per day for universities of 10 liters/student/day. The volume of rainwater generated by the roof area of PLN Institute of Technology with an area of 1.024 m2 and the mainstay rainfall from 2012 to 2022 was obtained a total of 2.159,18 m3 per year. The storage tanks are made the size of each storage tank that can accommodate a volume of water of 300 m3 with a length of 15 meters, a width of 10 meters and a depth of 2 meters. By using the rainwater harvesting system at PLN Institute of Technology based on the calculation of the potential for meeting water needs, there is an excess of harvested rainwater of 1,202.78 m3 when the number of users is 10% and as much as 248.78 m3 when the number of users is 20% that can be accommodated for use.

Abstract

The increasing demand for concrete in the construction industry continues to progress every year. Various concrete innovations have been developed to meet the needs of projects that require fast turnaround times and high efficiency but have a negative impact on the environment. Concrete waste as a solution to reduce construction waste, silica fume as a substitute for cement, so that it can reduce the use of natural materials and increase the resistance of concrete to cracks and corrosion, and superplasticizer increases the strength and flow ability of concrete. This research focuses on the use of silica fume and concrete waste as a partial substitution for concrete materials, as well as the use of superplasticizers to increase the compressive strength of concrete. Silica fume is used as a cement substitution with variants of 0%, 5%, 10%, and 15%, concrete waste is used as a substitute for coarse aggregate by 25%, and superplasticizer by 1%. In normal concrete and variants 1 to 4, the compressive strength value at the age of 28 consecutive days is 25,370 MPa; 26,125 MPa; 26,597 MPa; 27,634 MPa; and 29,520 MPa. The tensile strength is 2,025 MPa, 2,122 MPa, 2,146 MPa, 2,334 MPa and 2,594 MPa, respectively. Through this study, the right composition was obtained to make concrete with high initial compressive strength, the percentage increase in high initial compressive strength value at the age of 3 days was 47.110%.
